Snake Predation in Taiwan - Observation of the Week, 10/10/23

Our Observation of the Week is this predation event: a Brown Spotted Pitviper (Protobothrops mucrosquamatus, 龜殼花 in Chinese (traditional)) eating a Taiwanese Gray Shrew (Crocidura tanakae, 台灣灰麝鼩 in Chinese (traditional))! Seen in Taiwan by @r_cj!

“When I was young, I was very interested in the flora and fauna that surrounded me. At first, I just observed the plants, birds, and insects in my elementary school campus. Observing ants alone could occupy my entire afternoon,” says Chen Jin, a student at National Taiwan University (NTU). 

After joining NTU’s conservation club, she started becoming involved in night observations, and she also met Janus Olajuan Boediman (@janusolajuanboediman), a senior at the university, who taught her about finding snakes at night.

And Chen Jin was doing that exact thing this June when she came across the snake you see above. She first encountered it was it was lying beside the trail, waiting for prey. 

Unexpectedly, on the way back, I was fortunate enough to see it just after catching its prey. At first, it held the prey by the neck, seemingly retreating to avoid the approaching ants. Once it got away from the disturbance of the ants, it quickly adjusted the position of the prey and began to swallow it from the head. From the moment I saw it to its swallowing the last part of the tail of the prey, the whole process lasted about four minutes. After completing its meal, it stayed in place for three minutes, then slowly moved toward the location where I had first seen it on my way out and disappeared from my sight.

Brown spotted pitvipers range throughout much of Asia, from India to southeast Asia and Taiwan, and like all vipers evenomates its prey using hinged fangs which move forward when a bit is delivered. They generally grow to a length of 112 cm (44 in). 

And while shrews are sometimes confused with rodents, they actually belong to a completely separate family: Soricidae. While rodents have two pairs of ever-growing incisors, shrew teeth are sharp and pointy, and some are even venomous!

Speaking of mammals, Chen Jin (above with a Pareas atayal snake) has also started monitoring and research the monitoring and researching the masked palm civet “in urban areas such as Taipei and around NTU campus, as I’m concerned for the wild animals that are trying to survive in the constantly expanding city and avoiding the threat of free-ranging urban dogs.”

She’s been on iNat since 2019, and says that

at first, I used iNaturalist to assist me in identifying species, combined with the Seek app, which made me more curious about the surrounding flora and fauna. I often opened the app to try to learn the organisms around me, increasing my curiosity about biology. Starting this year, after beginning night observations and buying a camera, I started using iNaturalist as a platform for recording observations of species and also helping identify observation records uploaded by others, while practicing my own species identification skills.

Update on Taxon Frameworks

iNaturalist works best as a tool for helping people collaborate around species identification when there is clarity about the taxonomy everyone is referring to. This also makes it easier for iNaturalist curators to maintain the iNaturalist taxonomy when it's clear what direction they should be curating in. Five years ago we introduced Taxon Frameworks as a tool to help provide this clarity by explicitly referencing taxa on iNaturalist to external taxonomic references.

Since then, the number of Taxon Frameworks with external references has increased. The World Registry of Marine Species is now being used for nearly all Animal Phyla outside of Arthropods and Chordates. All Chordate taxa are linked to references such as the Reptile Database and Catalog of Fishes. Plants of the World Online is the reference for Vascular Plants. We still have no taxonomic references for Kingdoms such as Fungi and Chromista.

For Arthropoda, the vast majority of groups lack references. But most of the few arthropod groups we did have references for such as Mantids and Phasmids were referencing the Species File Group. This month, the Species File Group migrated to a new system known as Taxon Works. As a result, we were able to rewire these taxon frameworks up to their new home and add a few more branches on Taxon Works such as Harvestmen, Grasshoppers, and True Hoppers.

The pie chart below shows these taxonomic groups by percent of observations. 68% of these observations (colored areas) now have taxonomic references. This is thanks in part to complete coverage of Vascular Plants (green - 39%) and Chordates (blue - 20%). Of the other large group, Arthropods (24%), only 23% have references. The 3 large insect orders Lepidoptera, Coleoptera, and Hymenoptera account for most of these Arthropod gaps. At 6%, Fungi is the other large gap in taxonomic coverage.

We’re very excited that Taxon Works is providing a platform that makes it easier for taxonomic providers like the Species File Group to maintain and share their taxonomies. We hope these tools will facilitate progress filling gaps like Lepidoptera and Fungi in the coming years. iNaturalist derives huge benefit from access to well maintained global taxonomies. Our sincere thanks go to those maintaining the taxonomies the Taxon Frameworks depend on such as:

Chordates

Arthropods

Other Animals

Vascular Plants

*Managed in an instance of TaxonWorks

A Fungus Root is Not a Fungus - Observation of the Week, 10/17/23

Our Observation of the Week is this Fungus Root plant (Balanophora fungosa), seen in Australia by @donalddavesne!

“I stumbled on this strange Balanophora plant while on a hike in Far Northern Queensland, where I was traveling for a scientific conference,” says Donald Davesne, who’s currently working as an evolutionary biologist with the Museum für Naturkunde in Berlin and the Muséum national d'Histoire naturelle in Paris. 

My first thought was that it was a mushroom, but looking more closely I quickly realized the presence of flower parts and leaves. The thing lacks any green, which explains why it could be hard to recognize it as a flowering plant. I deduced this is because this plant functions the same way as the broomrapes (Orobanchaceae) that I knew from my home continent. It is a parasite that feeds on other plants and lost the ability to produce its own energy through photosynthesis.

As an evolutionary biologist, I was thrilled!

If you take a close look at fungus root plants (and yes, they do parasitize other plants), you’ll see that there are two types of flowers. The rounded top part is covered in tiny, tiny female flowers, and the larger male flowers grow near the base. The flowers emit a “mousy” smell which seems to attract all sorts of pollinators, from insects to rats. Several insects use parts of the plant as breeding chambers.

Donald (above), who’s studying the evolution of teleost fishes, says he’s always been interested in nature but his experience as a field naturalist is somewhat limited and mostly came via the Timarcha Association when he was a student in Paris. That’s changing, however. 

I started using iNaturalist right after the first COVID lockdowns in 2020, though, and haven't stopped since. Using my camera to document everything I see, and putting observations on the website made me learn so much, not only on the organisms I am most familiar with (vertebrates) but also on other stuff like plants.

We’re now modeling over 80,000 taxa! A conversation with Alex Shepard

We released a new computer vision model today. It has 80,962 taxa, up from 79,797. This new model (v2.8) was trained on data exported on September 17th. We’re celebrating crossing this 80,000 taxa milestone with a conversation with iNaturalist machine learning lead Alex Shepard.

Alex, you’ve been with iNaturalist since 2014. How did you first get interested in computers?

I have an undergraduate degree in history and a masters degree in fine art, but I come from a family that worked for Apple. So as a kid, I always had access to computers. I taught myself how to program as a kid not because I wanted a career as an engineer but because I’ve always been around and love computers. I’ve always found this stuff to be fascinating.

How did you first get iNaturalist involved with machine learning and computer vision?

I was excited for a long time about some kind of statistic or tool to help the community make identifications. We had a tool called the Identotron that let you choose species based on things like color and location - a sort of primitive trait based matching. I was looking for ways to improve that and was coming up with pretty dumb approaches. For example, I was looking into clustering the kinds of species people were seeing to try to predict what they might find next. Around 2016, there were these breakthroughs in computer vision that caught my attention. Before that, there were models that could do things like recognizing hand-drawn digits - very simple recognition tasks like that - or could recognize the same face from the exact same pose, but they couldn’t recognize that face from other angles. Deep Convolutional Nets were the first kinds of models that could do that.

How did you go from those explorations to iNaturalist releasing its first computer vision model?

There were a lot of things that fell into place at the right time. People were just coming out with open source tools to help build on these Deep Convolutional Nets that I had access to experiment with. At the same time, NVIDIA very generously donated a GPU that we could use to train models beyond the experimental proof of concept phase. We also met Grant Van Horn and colleagues at Visipedia who brought a huge wealth of formal background in machine learning and statistics. Beyond the fact that we trained our early models on their code, their help and all the things they were able to teach us was invaluable - ranging from how to train out full models to training models with performance and at scale, to how to pick the right photos, to how to know when we’re done training, all those things.

How have these machine learning tools integrated into the iNaturalist community and platform?

We really started with the goal of easing the burden on the community identifying all these photographs. As a tool, computer vision gives the identifier a great starting place that’s a good ballpark. On the other hand, the model often makes predictions that aren’t correct. It’s just meant to be suggestions, but it does enter the whole conversation about things like data quality. This is an ongoing challenge for us. I think iNaturalist data quality continues to be really good on the whole, but we have to be vigilant about data quality and how the Computer Vision Model feeds into that.

What are we not currently doing that you’re excited about?

There’s a bunch of technical things that I’m excited about and want to get to but we haven’t yet. For example, I think bounding boxes could really help improve accuracy and there’s interesting roles for the community to help us do that well. I’m really interested in model explainability. For example, can a model not just suggest what’s in the photo but tell you why? And I’m always interested in finding ways to help improve accuracy of our models and improve the speed at which we train. Our dataset size is growing rapidly so we have to keep finding ways to increase our capacity to train, ranging from tweaking what we have and exploring entirely different kinds of training architectures. I’m interested in how the Computer Vision Model and the Geomodel can better work together to offer suggestions. Likewise, can we model other parts of iNaturalist in ways that help us better understand iNaturalist or help us understand species in ways that make the platform more engaging? Lastly, I’m interested in these models teaching us new things, so we’re not just using the model to represent or synthesize human knowledge already in the community but using these models to actually teach us something new about the natural world.

The model released today has over 80,000 taxa, how has the model grown over time?

Our first model was released in 2017 and had about 13,000 species in it. In 2019, we had a Microsoft AI for Earth grant to make improvements to how we made predictions up and down the taxonomy. This is the model that we used when we released the Seek in-camera suggestions. In 2021, we got an Amazon Machine Learning Research Award and used this opportunity to figure out how to speed up training time to reduce turnaround time to get new information from the community reflected in the model. The first model using this approach in 2022 (1.0) had 55 thousand taxa. Since then in monthly model releases we’ve been adding 1 to 2 thousand species each time leading up to today's model with over 80 thousand taxa. We’ve been training all of these models off of donated NVIDIA GPUs. Thank you NVIDIA!

Is this sustainable?

Good question. If you think about the model as a dice where there’s some probability associated with each side, we now have an 80 thousand sided dice. Every time we add a side it’s slightly harder to get the right answer just because there’s more choices. I’m really proud of the fact that we’ve been able to keep accuracy high despite adding so many new choices. I think this has a lot to do with the high quality of the iNaturalist data we’re training on. But we don’t know if there are limits we will hit down the road. We’re constantly working to squeeze a bit of accuracy out of the model or shave some time off of training runs. We’re definitely reaching the limits of our current set of hardware. There’s always work to do.

Final thoughts?

Sometimes we talk about adding taxa to the model as adding rarer and rarer species, but I like to think of this as adding common species from increasingly overlooked parts of the globe. This makes me happy because I know as the model grows we’re making iNaturalist more useful and available to more and more people from around the world.

On that note, here is a sample of new species added to v2.8!

A "Giant" Springtail - Observation of the Week, 10/24/23

Our Observation of the Week is this Holacanthella paucispinosa springtail, seen in New Zealand (Aotearoa) by @frankashwood!

“I became interested in nature as a young child – some of my earliest memories are turning over rocks in the garden and my mum explaining to me what all the different invertebrates were,” recalls Frank Ashwood. 

So, it’s a childhood dream come true that I now work as a professional soil ecologist and hobbyist macrophotographer, spending my days researching and photographing all those same animals that once fascinated me as a child. Fortunately for me, I recently moved to New Zealand, where there’s some of the most spectacular soil invertebrates in the world – particularly the giant springtails!

A few weeks ago, Frank participated in an event organized by the University of Canterbury, held at the Cass Mountain Research Area.

I knew H. paucispinosa was in the general area thanks to a colleague previously finding one nearby (shoutout to @fuligogirl on iNaturalist), so I was on high alert for it while turning over deadwood for invertebrates. However, a whole morning passed without finding one, and just as I was about to give up hope, I turned over the right log and found a pair of them huddled together! This is one of the five species of Holacanthella endemic to New Zealand, and they’re not only incredible creatures to look at, but are also important decomposers of decaying wood in native beech forests.

While they do have six legs, springtails are not considered insects. They instead belong to a separate subclass of hexapods, and lack the external mouthparts which insects have. Most springtails have a furcula, an abdominal appendage which can be released with great force, propelling the animal into the air when it needs to escape a predator. Most springtails are shorter than 6mm in length, but members of Holacanthella can be 17mm long - truly enormous (relatively).

"I only started using iNaturalist a couple of months ago, when I moved to New Zealand from the UK," says Frank (above). 

It’s very popular with the naturalist community here, so I decided to give it a try. I’ve found the app’s community-based approach to identification has helped me learn native species ID much faster than if I’d had to start from scratch. It’s also given me greater confidence in recording organisms outside of my usual areas of expertise, as I don’t have to know the exact species to still make a useful biological observation.

Identifier Profile: @ajott

This is the twentieth entry in an ongoing monthly (or almost monthly!) series profiling the amazing identifiers of iNaturalist.

“I was always fascinated by how things work and wanted to get to the bottom of things,” Dr. Anja Junghanns recalls when describing her childhood in Germany. 

When I was maybe 5 or 6 I was sure I was the first person to realize where mosquitoes come from. I had found some small wiggly critters in the rain barrel in our backyard and decided I needed to take a closer look, so I put them in jars and other translucent containers to observe them. I soon realized that they would change at some point into what my childish imagination termed “waterponies” (pupae) and was rather surprised to find mosquitoes later on in those closed containers. When I at some point was able to observe how one of those “waterponies” released a mosquito to the world I was in total awe (and maybe a bit disappointed to later find out that this was already common knowledge).

She’d also smash rocks with hammers to get at what was inside them (with protective goggles on, of course), consume nature documentaries, and was especially fascinated with arthropods and herps. “I was always especially interested in the parts of nature I had the least information about,” she explains.

Since joining iNaturalist a few years ago, Anja has identified over 76k spider observations, but says that “As an arachnophobic, diving into the spider world was actually a last resort for me.” She resided in a cool garden shed, but the downside is that it attracted “masses of large and hairy spiders each autumn and spring.” Feeling like she might have to move out due to the arachnids, she photographed these two spiders in 2010 and tried to identify them.

I still recall how disgusted I was by it and at the same time fascinated. It was also the moment I realized that it was easier for me to deal with spiders looking through the viewfinder of a camera.

I learned that the hunting spider in this observation (Scotophaeus) was actually my friend and would hunt down those huge hairy ones that I so despised. So I tried to learn to tolerate them. And it was all a slippery slope from there. I found more and more species in my tiny house and learned about their amazing hunting skills (Ero spiders, which while tiny are also spider hunters), their somehow lovely maternal behaviors (a lot of spider moms will protect their breed until death) and their impressive senses and other curiosities (like many spider males being basically mating machines only, often losing interest in basic surviving mechanisms like feeding).

So in 2012 she decided to study spiders for her thesis and ended up researching matriphagy in Stegodyphus spiders, along with some Danish and Israeli specialists. 

Matriphagy means that a spider mom will be eaten by her young before they disperse from their nest - a rather extreme and deadly behavior for the spider mom to secure their babies survival .. and which is connected to the extremely rare and therefore especially interesting case of social evolution in spiders (only about 25 spider species of about 55,000 known species today can be termed “social”). During my PhD I dug deeper and deeper into this topic which culminated into my thesis on “Evolution of Sociality: mechanisms and dynamics of social behavior in spiders”. To this day I am still in love with Stegodyphus spiders.

Anja and her partner have, for several years now, been living in different parts of the world and that included Ecuador in 2020, which is when she joined iNat because she wanted to learn about the unfamiliar wildlife she was encountering there. She initially started identifying observations here as a way of giving back to the community.

Websites like this do not function well if everybody just wants to get something out of it but not give back. It is basically how I learned to use and participate on the internet very early on…So the first months and years on iNat I tried to at least do 3 identifications for every observation I put on here. My interest in identifying spiked significantly since last year, as living in Bogotá does not allow me to take my camera out every day and observe a lot (for safety reasons and also as the capital itself is surprisingly low on insects unfortunately.). So identifying increasingly became an outlet to stay connected to nature. And I quickly started to fall in love with the dedicated, helpful and interactive spider identifier community here. Now identifying is a means for me to relax, connect and learn.

Having such a mobile lifestyle means that Anja doesn’t have a lot of physical references, so she generally uses online ones. 

For European spiders and their distribution there are some great websites I use to get species lists first (e.g. https://wiki.arages.de/ and https://araneae.nmbe.ch). The best source of spider information for worldwide endeavors is the World Spider Catalog. However, one needs to already have at least a bit of a clue about what genus one is interested in and can check distribution of individual species and scientific source material from there. When diving into a new taxa I will always try to go back to the scientific papers published on the taxa from there and will often through references in said papers dive deeper and deeper until I get a good understanding about how to distinguish a certain taxa or what other similar species to be aware of.

When I identify I will check my “usual suspects” (Stegodyphus, Argiope worldwide, Pisaurids in Europe and North America) first to keep up with them. If I still have more drive to ID after that, I decide what I am most interested in that day. Sometimes I pick a certain species in a certain place and will work through the “Needs ID” observations. Other times I feel like I want to push some of my own “needs ID” observations further and will dig into the topic of a certain taxon.. usually also ending up IDing for others, when I find out more about them. Sometimes I will quick and dirty go through Araneae worldwide and will often just be able to put it to family, sometimes genus. I enjoy how those “mental trips around the world” show me the amazing variety of our eight-legged friends.


Anja’s advice for taking spider photos:

Observing spiders can often be a bit disappointing, as it is often hard or impossible to ID them to species with typical observation photos. Many species (especially in many non-web building spiders) have sister species with near identical characteristics and can only be distinguished by observing the genital features as well - which is often impractical or impossible in the field. However, for cobweb builders I would always try to get a good shot from the ventral and dorsal side if possible. If you are lucky, the ventral shot is good enough to examine important features of the epigyne (the female genital region). Sometimes being able to clearly see certain hairs and bristles on the legs and palps of the spiders can make the difference between being able to go to species or having to stick with genus or complex. Habitat can also be an important information in some species. So taking some time to either take a photo that includes the habitat or give a description of it might make a difference (e.g. moist or try, forest or meadow, wilderness or around the house...)

Generally, I would advocate for a more relaxed approach to spider IDs.. it is fine to stick with genus sometimes and a lot of my own spider observation will never go to species ID as well.


Aaand some of Anja’s favorite spider taxa and observations:


- the first identifier profile was of @naufalurfi, another spider identifier!

- iNat was recently mentioned a few times in this article about the importance of documenting spiders, and how doing so can help people appreciate and like them more.

iNaturalist October News Highlights

We are embracing the Halloween spirit with a spider theme woven through these iNaturalist impact highlights from October 2023! If you missed last month's highlights you can find them here.

Invasive Species Science


@ashleytwahlberg’s new study in the Journal of Arachnology used iNaturalist data to assess the invasion of the Brown Widow Spider across the Americas. Similarly, @dcoyle and colleagues at Clemson Extension are using iNaturalist to track the invasive Joro spider in the southeastern United States.

Not to be outdone, October is also Spotted Lanternfly season. You can read here about @tanya_campbell’s observation documenting lanternflies creeping into Canada and iNaturalist help tracking this invasion from Maryland to New York. This story highlights @drcrayfish’s help identifying invasive crayfish in Canada, while this story highlights iNaturalists use in understanding the Chinese Mitten Crab invasion in the United Kingdom.


Climate Change Science


Leaving our spider theme for a moment, our favorite climate change story was about @sgorta and colleagues using iNaturalist data to understand biodiversity responses to recent Australian megafires.

Check out this study using iNaturalist to understand the climate change impact of methane emissions from termites, and this story about @clairegoodwin_hmsc’s work using iNaturalist to document out-of-place species in marine ecosystems driven by climate change.


Science Discoveries


Our favorite science discovery from October was this story about @louwclaassens use of iNaturalist to discover a new species of pipehorse. The effort leveraged the iSeahorse project on iNaturalist which turned 10 years old this month.

There were many examples about range extensions like this story about @nedster and @nicolem42’s discovery of Lemon Cuckoo Bumble Bee in Illinois, @silviatav’s study on the discovery of stalked jellyfish in Portugal, a worm lizard range extension in Brazil, new millipedes reported from the Canary Islands, and hybrid buntings reported in Russia.


Conservation and Monitoring


Back to our spider theme, this great article makes a compelling argument for how observing spiders can help us understand why they are declining with iNaturalist anecdotes from @mira_l_b and @bnm50.

In other news, Newsweek and CapetownEtc told the story of @eugene_hahndiek’s thought to be extinct flower posted from South Africa that Custodians of Rare and Endangered Wildflowers (CREW) identified. Read more about CREW’s use of iNaturalist in this recent Biodiversity and Conservation article. We loved @elia_van_tongeren and colleague’s paper on how iNaturalist helped understand butterfly extinction patterns in Italy and stories about monitoring declining Christmas beetles and bandicoots in Australia.



Don’t miss ScienceFriday’s excellent piece on @akilee and colleagues monitoring the spread of Beech Leaf Disease. This article described @scott654’s study assessing potentially at risk Illinois hoverflies, while other studies used iNaturalist to assess West Atlantic marine taxa, butterflies in Ecuador, and cactus biogeography.

Lastly, we couldn’t resist this photo from @rony_alberto_garcia_anleu of @seyner and Wildlife Conservation Society colleagues using iNaturalist to monitor species in Guatemala’s Maya Biosphere Reserve.


Roadkill and Landscape Connectivity


No spiders here, but equally ghoulish, this article highlighted the value of roadkill observations @damonyeh and colleagues’ Tahoe Basin Connectivity Study. In Australia, this story described @katyw’s use of roadkills on iNaturalist to find wombat road crossing hotspots as part of her rescue work. Roadkill observations helped @raul_pommer and colleagues study the distribution of Crab eating fox in Brazil while this story links reporting roadkills to iNaturalist with snake conservation in Vancouver.


iNaturalist Impact on AI Research


Yesterday, New Scientist described mind-blowing research by @carlosemunoz using iNaturalist images to train a Neural Network to show how insects like @tshahan’s moth pictured here mimic spiders to avoid predation.

iNaturalist images contain a tremendous amount of information that help scientists study everything from how monarch caterpillars and woodsorrell are changing color to adapt to climate change, to helping morphologically delineate Chilean geckos, to public health science around exposure to poison ivy, to @marinejanine’s sea dragon behavior research.



iNaturalist images and AI tools are supercharging this Phenotypic Revolution by allowing scientists to more easily detect and measure phenotypic patterns. Two articles on image analysis with iNaturalist appeared in this month’s special issue of Applications in Plant Sciences. One offered new tools for extracting color patterns from iNaturalist images while the other outlined new techniques for improving the usefulness of iNaturalist photos for image analysis.

Meanwhile, the iNaturalist dataset has become a standard benchmark dataset for the Computer Vision community as evidence by its use in papers this month by Jinglun Li et al., Panos et al., Lianbao Jin et al., Zikai Xiao et al., and Anonymous authors. Caltech incorporated an iNaturalist scavenger-hunt into an AI event on campus this month which highlights this virtuous cycle between iNaturalist and the AI research community.


iNaturalist for Land Stewardship


This role of iNaturalist in bridging native species, bioregionalism, and stewardship was highlighted by author Jenny Odell in a talk from earlier this month. We were inspired by @thenectarbar’s quote: “if every single person would make a 10-foot by four-foot space and dedicate it with native plants then we are doing our part to put the diversity back” from this story about Texas gardeners using iNaturalist to identify native plants. @robdv’s excellent article describes using iNaturalist to attract native insects while this article highlights using Seek to help rear and restore butterflies. Beyond planting and attracting native species, @andreakautz explains in this article how iNaturalist can be used to identify and remove invasives from gardens.

This article details the excellent work of @vmacphail and other Pollination Guelph volunteers who used iNaturalist to log hundreds of species at restored sites that were just bare sod a few years ago. Other events that incorporated iNaturalist into restoration themed events included this story on Rosemont Preserve Restoration Day, this story on the upcoming Armour Hill Clean-up, and this story on the Wall Street Journal’s Giveback Day 2023. Lastly, this story highlights @luisfssantos and colleague’s use of iNaturalist to document a rare plant as part of efforts to purchase and preserve a Portuguese wetland.


October iNaturalist Events


Coverage of spider themed October events included the North Carolina Spider Search and Aracnoctubre. Keeping with the Halloween theme, we loved the coverage of the Life in Our Cemeteries iNaturalist event in Australia.

Student led bioblitzes were highlighted in this article about the North Carolina Campus Nature Challenge, and this article about the CASS Minibioblitz in New Zealand. Lastly, this video features a Wisconsin Tyke Hike by the Delafield Public Library in Wisconsin.


iNaturalist’s Human Health Impact


This article profile’s @scarlett_smout’s research on healthy bodies and minds and her use of iNaturalist. Likewise, this Guardian article endorses iNaturalist and Seek as great apps for connecting to nature. But how do people connect to nature if they can’t get over their fear of creepy crawly things like spiders? Backpacker editor and spider enthusiast Adam Roy describes how and the role of iNaturalist in this excellent podcast.

Several stories mentioned using iNaturalist in seasonal nature activities to help people connect to nature such as enjoying fall foliage in Central park with @carey_russell. Many stories focused on mushroom hunting ranging from this story on @allthingsfungi’s efforts to get people overcome their fear of fungi, to @mycology_mike leading mushroom hunts around Oberlin College, to @nschwab’s Mycoblitz Europe project, to this story about @bdthomas mushroom foraging in Rhode Island. This article describes using iNaturalist to get started with foraging. Please remember to forage responsibly!


iNaturalist’s Education Impact

This study details @ulfi_faizah's experience incorporating iNaturalist into a University biology course in Indonesia, while two separate Brazilian studies assessed iNaturalist’s use as a remote learning tool for teachers here and here. This article on @biolily’s work at Autonomous University of Nuevo León high schools in Mexico exemplifies how great teachers are using iNaturalist in the classroom. Also check out this article on @craig_williams work using iNaturalist to build curricula around mosquito monitoring in Australia and this article on @ptimmldne use of iNaturalist with students in Nebraska.

iNatters in the News

This month, we featured spider researcher @ajott in an identifier profile. We loved this profile on ecology professor and bird photographer @phylogenomics. Check out this article on scientist and prolific iNaturalist identifier @cehmoth’s work to catalog moths in Montana. This profile highlights Native Bee Society of BC's Bee Tracker creator @beespeaker’s work helping pollinators. This article highlights @jlmason’s work conserving the Ontario Carp Barrens, and this article summarizes a talk by @danbachalis about surveying species in Hammonton, New Jersey.

Thank you to everyone who participated in iNaturalist this October! Your support makes it all possible.
