Identifying a fish

Australasian Fishes is closing in on its 50,000th observation. Of those, more than 95% have been identified to species by more than 1400 people. This is an extraordinary effort; thank you all!
Why, you might ask, aren’t they all identified to species? There are a number of answers to that question, more than one of which may apply to a single observation.
Let’s start with a couple of obvious reasons, image quality and size of the fish in the image. If the photo is poor, or the fish only occupies a tiny part of the image, it may be difficult to see the diagnostic features. In addition, the angle at which the photo is taken sometimes results in diagnostic features not being visible.
For some observations, the shape and colour pattern of the fish may not be enough to identify it. In the case of beach washups, the colour pattern of the fish may be lost entirely. Sometimes, the photo may be fine but closeups are required. In other cases, counts of fin elements, gill rakers or even internal morphology is required to make an accurate identification. And don’t get me started on identifying hybrids! Of course, the fish faunas of Australia and New Zealand aren’t fully discovered. Sometimes observations of potential new species are uploaded, such as the two above.
So well done everyone! Who would have thought when the project started in October 2016, that in less than 2.5 years we’d be looking at nearly 50,000 observations, the majority of which are identified to species.

Checklist of crane flies in the subgenus Tipula (Yamatotipula) that are possibly in Florida

Many of these have not actually been recorded from Florida, but may exist there solely based on the fact that the Catalogue of Craneflies of the World by Oosterbroeck does not provide the southern limits of these species. The ones that have been recorded from Florida are marked with an asterisk (*). Southwestern species are hardly known at all. Even though species recorded from the southwest may still be found east because of limited information about their ecology, western species tend to favor the north rather than south. Tipula jacintoensis and T. comanche are recorded only from California and Texas, respectively, but it is doubtful that their southern range extends east. Therefore, I do not include western species here and in the previous eastern lists.

Field Obs3: Social Behavior and Phenology

Date: 13-March-2019
Time: 4:00-6:00PM
Location: Puerto Villamil, Isabela Island, Galapagos, Ecuador
Coordinates: -0.9533, -90.9864
Weather: Sunny, partly cloudy, 80°F (27°C)
Habitat: Mixed (see first paragraph below)

I was extremely fortunate to be taking a spring break course in the Galapagos Islands studying conservation and the natural history. Beforehand I ensure I purchased a nice camera so I would be able to take pictures of the marvelous and diverse birds that reside in these unique islands. The islands are notorious for their rapid changes in scenery, in a single 30-minute drive I was able to see beach, desert, tropical rainforest, and high-altitude volcano ecosystems. The hostel I was staying at was right on the beach and was a short 2.5-mile walk to a dry, dusty, tortoise breeding center which followed a boardwalk through a light forest and a lagoon back to the hostel. This unique setting allowed me to see a wide variety of birds from extremely different environments all within 90 minutes of each other.

I started the walk at my hostel, where there was a local, friendly Yellow Warbler that joined us for breakfast every morning. I was happy to see my little friend right before embarking on my excursion. Along the beach, I observed shorebirds, primarily Whimbrels and Sanderlings. These birds are generally solitary foragers, although Sanderlings could be observed in small foraging groups, although little interaction occurred. These birds were primarily observed foraging along the shoreline at dawn and dusk in order to escape the heat. Frigate birds and a Brown Pelican were also observed flying by, but it was not uncommon to see these birds flying solitary in the sky at any time of the day. Many Frigate birds observed during the trip had a large, red sack underneath their neck which they are able to inflate to attract a mate, indicating a fully mature male. This inflation is a major communication method male use to try and attract a female in, the larger the air sac, the more likely they are to obtain a mate. Other Frigates had a white, feathered neck, indicating that they were either juvenile males or females.

Once at the tortoise breeding center, a Galapagos Mockingbird was immediately spotted in a nearby low-lying tree. There are two other Mockingbirds found in the Galapagos, but these birds are able to differentiate each other due to their variety in plumages, although not an issue as many of these species are separated by islands. Although they have wings, they prefer to hop and walk around, limiting their dispersal and hybridizing abilities. A Smooth-billed Ani was seen drinking water out of one of the tortoise’s baths. These birds are generally found in groups of 10-40 birds and communicate with a variety of calls, although this bird was seen alone. While leaving the breeding center, I walked through a low-density forest of smaller trees where various finches were observed. A Sharp-beak Ground-finch and a Medium Ground-finch were seen in close proximity of one another, and although descendants of the same finch and very similar in physical attributes, these birds are not the same species. The thirteen finches that reside in the Galapagos actually all developed their own unique calls and will not respond to that of another finch. So, although these two birds were heard chirping similar notes in close proximity of one another, they were not communicating.

After exiting the forest, a boardwalk led me through saltwater lagoon where a flock of Greater Flamingos was observed communally foraging. Flamingos of all sub species on a global scale can be found in flocks ranging from 10 individuals to upwards of 200, the flock I observed had approximately 20 individuals. One several birds were observed foraging, perhaps suggesting this was not a peak foraging time, or perhaps could mean they all forage at different times. Most notable about the Flamingos is their bright pink coloration, which is not used for communication but is a side effect of the keratin found in the prawn and shrimp their diets primarily consist of. It is not entirely known how and why their bodies process the pigmentation the way that it does, but it is truly beautiful to see. Younger Flamingos had more grey-white coloration, but after eating more keratin-rich shrimp, their plumage will mature to the gorgeous pink color seen in the adults. Other lagoon birds were observed as well, including the White-cheeked Pintail which was seen in close proximity to other individuals, but no verbal communication was noted. Two Yellow-crowned Night Heron were observed independently of each other, these birds generally forage alone so I was not surprised to not see it within a group. Additionally, it is a nocturnal bird, so observing is at almost at dusk time was appropriate with its feeding and circadian schedule.

Although the Galapagos is extremely diverse, there are not many foraging flocks of smaller birds that would respond to pishing. Fortunately, I do this often when in Vermont forests to try and attract smaller, flocking birds like Black-capped Chickadees and Tufted Titmouses. By either making a “pssh” noise or a whistle, it indicates to smaller birds that the area is safe enough from predators that another organism (me) feels safe making noise. The birds aren’t confusing my vocalizations as another of their species trying to communicate, merely using it as an environmental cue that the region is safe for foraging. Larger birds generally don’t respond to this kind of noise because they primarily use vocalizations for intraspecific communication and not as environmental cues for safety.

Crucial animal protection laws for the sage grouse being eliminated by the White House.

The White House is eliminating crucial animal protection laws for the sage grouse. The protections, originally put in place by President Barack Obama, are being rolled back to open millions of acres of land for gas and oil development. Conservationists warn the move could land the sage grouse back on the endangered species list.

A California battle over swordfish — and gill nets.

Conservationists are pushing a $1 million effort this summer to change the way swordfish are caught off the California coast by phasing out the use of gill nets. They are the mile-long nylon nets used to catch swordfish but that also ensnare other species, causing conservation organizations to seek an end to their use.

Aquatic Invasive Plant Survey Updates

Hello Everyone,

We are up to 650 observations from 196 observers in the Aquatic Invasive Plant Survey project! Thank you to everyone who has helped so far.

This is a brief orientation to the project goals and update on AIS in Ohio's Lake Erie Basin. For more info send me a message here or shoot an email to mjw1@clevelandmetroparks.com.

Data collected here will be shared with the Ohio Department of Natural Resources as part of an effort to record invaders in Ohio's Great Lake drainage. iNaturalist records may also be picked up by national efforts like the Nonindigenous Aquatic Species database from USGS. Two goals of this project are to stop the spread of invaders and prioritize which plants receive management activities.

In order to pick which plants get the 'boot', we need accurate information on plant distribution and abundance. Two species of nuisance vegetation that we stand a good chance to detect early are Hydrilla verticillata, http://hydrillacollaborative.com

And starry stonewort (Nitella obtusa), which is technically algae:
http://fingerlakesinvasives.org/starry-stonewort-collaborative

So keep the plant and habitat pictures coming! If you are new to the world of invaders and underwater forests I recommend the Ohio AIS guidebook - https://ohioseagrant.osu.edu/products/4j7wz/ohio-field-guide-to-ais

If you have access to a permanent waterbody that falls in this project, please get in contact me. We may be able to survey together in the field. I appreciate suggestions, too!
Thanks, and happy almost-spring!

Field Observation 3 - Social behavior and Phenology

Date: March 17, 2019
Location: Salmon Hole (44.4870° N, 73.1881° W)
Weather: about 27 degrees F, mostly cloudy, fresh layer of about half an inch of snow
Habitat: mixed hardwood trees (some maple, birch, cottonwood)
Other: some of the trees have started budding, lots of snow/ice melt occurring, ice that was covering certain sections of the river is breaking up
Arrived: 9:47 am
Departed: 11:38 am

This birding outing was the most successful one I’ve gone on so far this semester. I went earlier in the day than my prior visits and the birds seemed much more active. In addition, since the weather has been getting warmer the past few days, there were more species around. Some migrants might also be back or returning within the next couple of weeks and will be exciting to see! This time I recorded a total of seven different species including the following:
• American Crow - Observed dozens at the far bank of the Winooski River by the dam and heard them calling
• Mallard - Observed at least a dozen floating down the river and heard them calling
• Herring Gulls and Ring-billed Gulls - Observed a large group, probably over 50, gathered in one section along the river and heard them calling
• Common Goldeneye - Saw one male foraging in the middle of the river
• Hooded Merganser - Saw one male and one female foraging in the middle of the river
• White-breasted Nuthatch - Heard one calling
• Tufted Titmouse - Heard one calling

There were many species gather within a fairly small area, mostly within a few hundred feet of one another or closer. This means they were all interacting with one another by sharing the same space. The Mallards, Mergansers, and Goldeneye were all foraging in the same area and didn’t seem to be expressing any antagonistic behavior. They all remained spaced out from one another. The Mallards were calling back and forth to one another, but I didn’t hear the other calling. The Herring and Ring-billed Gulls were all gathered in the same area with very little space between one another and were all calling loudly to one another. Maybe they were trying to adjust their spacing or communicate about the foraging. A few individuals at a time would fly out from the group and soar over the river and then return to the group. There was a large group of American Crows past the group of gulls and they were cawing loudly to one another as well. Occasionally some would fly from the river bank to the opposite site of woods, then return. None of the calls sounded particularly alarmed so the communication was probably mostly social or informational for other members of its species.

The American Crow is a very darkly colored species in comparison to Herring Gulls or Ring-billed Gulls. This allows them to absorb more light and generate heat. Against a light sky, the black coloration stands out, but in the evening or with the cover of trees, it can work as camouflage by resembling a dark shadow in the canopy. The Gulls are much lighter overall in coloration. The adults of both species are typically light gray on the back and wings, with the tips of the wings being black. The underside and head are white, which can be beneficial when foraging because the prey below looking up at a light sky and white underside are less likely to see them.

The single bird I focused on for about ten minutes was the Common Goldeneye. This species often forages in groups, but this male was by itself. He was floating in the middle of the Winooski River and every so often would dive forward and resurface a few seconds later. I didn’t see him come up with anything in his beak after any of the dives, but he could have already eaten the prey as he was resurfacing or was just not having success in hunting. This species is diurnal and therefore is most active during the day. It was around ten in the morning when I saw this one foraging.

Sister Sister: understanding the difference between sister taxa that look the same

One of the most challenging parts of studying this plant is complexity found not only within this species, but at higher levels of taxonomy as well. The genus Linanthus is distributed all across the California Florirstic Province, and while there are some consistent traits that shout out “Here I am!”, the amount of differences between species is astounding. This intuitively makes sense when you start thinking about the complexity of California landscape and differences in rain patterns and temperature, the giant chains of mountains limiting the dispersal to new places, and timescales on the thousands to millions of years.

Basically, this plant looks different depending on where you are. And to add more complications, there are a few other species that look like Eveningsnow (1), but they aren’t: Linanthus maricopensis is a large lobed annual flower found in central and southern Arizona and is identifiable by the glandular trichomes on the calyx and pedicel (there are sticky hairs on the green-maroon base and stem of the flower). Linanthus bigelovii (a sneaky imposter of Linanthus dichotomus) is an annual flower that is mostly found to the East of California, although many observations have been made in the Mojave and Great Basin deserts and even up into the Coastal Ranges of California (think an hour or two south of San Jose). There are two subspecies of in this lineage: ssp johnsonii and ssp bigelovii. Linanthus bigelovii ssp. bigelovii is a small lobed flower that looks an awful lot like L. dichotomus ssp. pattersonii and usually takes additional measures to confirm identification. L. bigelovii ssp. johnsonii look a lot like linanthus dichotomus with large lobes on the corolla but has small glandular trichomes along the calyx and pedicel whereas L. dichotomus is glabrous (or hair and gland free). Last but not least is the benign offender, Linanthus jonesii. This plant has small lobed flowers and glandular trichomes all over the calyx and inside of the upper leaves, so there is no real issues with confusion unless you’re whizzing by at 60mph.

So what’s the difference, you say? How do I see snow? Specifically, there are two. The first, is the insertion of the anthers in the corolla tube. In L. dichotomus, this will be more towards the base and have a hairy nectary at the attachment point of each one (1, pg 67-68). In L. bigelovii, this will be in the middle and will lack hairs and nectaries (1, pg 63).

Too late for flower season? Check out the seeds! In L. dichotomus, the seeds are surrounded by a lattice like white covering, almost like a mini bubble wrap (1, pg 68). This membrane leaves a little space between it and the tiny little brown seed. L. bigelovii, on the other hand, has almost vacuum wrapped this white membrane to the angular seed (1, pg 62), which becomes sticky when wet. Last but not least L. jonesii has cute little brown kidney bean seeds that do not have a membrane, so again, completely different.

Ok ok, yes, you are correct: Tearing apart a corolla to find out what kind of plant it is should be left as an emergency last resort, especially since I am trying to recruit as many participants as follows. Can’t tell if it is Linanthus dichotomus? Make a note to come back and check out the seeds! If you can’t, maybe someone else can! The nice thing about plants is they don’t move, so barring a heavy wildfire or a new mini mall, the stems should still be there a few months later with at least a few seeds still waiting to be dispersed.

How do you know a Linanthus?

Polemoniaceae is an adorable family of annual and perennial plants with almost all of its diversity found in North America. This family is known by its diversity in flower morphology and plant-pollinator relationships. Are you in to first person narratives of science theory, like Darwin? Then you will love Flower Pollination in the Phlox Family, by Grant and Grant (1). Verne and Karen were a husband-wife duo that studied and published together on all things pollination. This book is a culmination of observations, both personal and scientific, that discuss the diversity of plant pollinator systems in Polemoniaceae. While this book is somewhat outdated in its taxonomy (genomics have completely revolutionized plant taxonomy), it is beautifully written with excellent observations and personal touches, and does *in fact* write about Linanthus dichotomus. Great read if you like non fiction natural history books with a personal twist.

Back to the identification of Eveningsnow: Polemoniaceae is known by its 5-5-5-3 combo of flower anatomy parts: 5 sepals, 5 petals, 5 stamens (pollen producing parts), 3 carpels (chambers of ovules at the base of the flower; Can usually be counted by the lobes at the tip of the female anatomy, or where the pollen begins its journey).

See the following link for an excellent introduction to flower anatomy, brought to you by the University of British Colombia (famous for their plant research department):

http://blogs.ubc.ca/biol343/flower-structure-and-morphology/

In Linanthus, the sepals are not showy like the petals, but are instead more vegetative like in its looks with thin membranes that sometimes connect each lobe together. The leaves in this genus are needle like (not hard like a pine, but almost like mini-skinny succulents, sometimes with hairs). Flowers are all perfect (bisexual, aka both sexes present in one flower), and radial (you can draw a line almost anywhere through the middle and both sides will match). Corolla tubes are present, aka the petals are fused at the base before fanning out for show. The genus is almost entirely restricted to southern California deserts, Transverse/Peninsular ranges, and Baja, except for one species: Eveningsnow.

A great resource for aspiring botanists is the online Jepson Manual for the California Floristic Province. While it is not completely up to date it has great resources for botanical vocabulary, dichotomous keys, maps of known localities, photos and more. See the following like for the Linanthus section and don’t forget to check out the other beauties in this group!

California Tortoiseshell - Not a Painted Lady!

Painted and West Coast Ladies are not the only butterflies in the western United States to be undergoing an outbreak. California Tortoiseshells have also been present to abundant in some places in northern California and Oregon where Painted Ladies probably have not yet arrived in any large numbers. They look like this: https://bugguide.net/node/view/1447798. While they are interesting butterflies in their own right, and worthy of further study, they are not Painted Ladies, so please be careful not to confuse the two when reporting Painted Lady sightings. Also, according to a March 18 posting on DesertLeps, California Tortoiseshells have also become abundant in the area of southern California around the Santa Rosa and San Jacinto Mountains National Monument, replacing the Painted Ladies, which are surprisingly not that common there now and seem to have mostly departed the area. However, Painted Ladies were still abundant in southern California on March 16 near the Mescal Range in San Bernardino County, CA, about 138 miles (222 km) to the north-northeast; no California Tortoiseshells were observed there.

Ecología para todes: Plantas de La Pampa (Gobierno de La Pampa)

En esta publicación queremos acercarles una introducción al conocimiento de la flora de la provincia de La Pampa, aportando un listado de las especies más representativas de nuestra provincia. Se pretende que este material sirva de guía introductoria para el estudio de la temática,para que cualquier persona interesada en la flora autóctona tenga amano las bases para su reconocimiento. Para cada especie tratada se consigna el nombre vulgar, el nombre científico, la familia a la cual pertenece, una breve descripción de la misma, su distribución geográfica, hábitat y usos, si los tuviera. Estamos convencidos que el conocimiento de nuestros recursos naturales nos permitirá crear una mayor conciencia ecológica para con-tribuir a la preservación de nuestro ecosistema. A esta tarea está aboca-da la Subsecretaría de Ecología, y es por eso que queremos compartir nuestro trabajo con todos ustedes.
Dr. Darío Mariani Subsecretario de Ecología

Biodiversidad de Artrópodos Argentinos Vol 2- NEUROPTERA (Descarga)

Los Neuroptera incluyen adultos provistos de mandíbulas masticadoras, venación más o menos reducida y larvas provistas de un aparato bucal suctor. Es un grupo de gran importancia económica, ya que dos familias (Chrysopidae y Hemerobiidae) son utilizadas para el biocontrolde plagas agrícolas. Se halla distribuido prácticamente en todo el mundo, particularmente en regiones templadas y subtropicales. De los 78 géneros presentes en la región Neotropical, se hallan citados para la Argentina, con 143 especies, lo cual representa aproximadamente el 30% de la biodiversidad del orden en el Neotrópico. En el presente trabajo se dan claves para los adultos y larvas presentes en la Argentina. Se describen brevemente las superfamilias y familias y se dan datos sobre su biología. Además, se incluye un breve resumen de la historia delos estudios neuropterológicos en el país y del estado de las colecciones neuropterológicas argentinas. Se da una lista sistemática de los grupos presentes en el país y una completa bibliografía de consulta

Species of the Week -Eastern Cottontail

The Eastern Cottontail (Sylvilagus floridanus) is a medium sized rabbit, red-brown or gray-brown in color, with large hind feet, long ears, and a short, fluffy white tail. Its underside fur is white, and there is a brownish patch on the tail. They are herbivores.

The Eastern Cottontail is the most common species of rabbit found in North America! It’s in the family Leporidae, which includes all rabbits and hares. It’s a cosmopolitan species in North America, meaning that you can find it pretty much everywhere, including meadows and shrubby areas in the eastern and south-central United States, southern Canada, eastern Mexico, Central America and northernmost South America. It is abundant in Midwest North America, and has been found in New Mexico and Arizona. It is not native to New England, but has been introduced here, which puts it in direct competition with the native New England Cottontail. There are 18 recognized subspecies of the Eastern Cottontail, and they are considered of least concern by the IUCN, even though they are a popular game animal.

These rabbits breed 3-4 times a year and have about 8 young per litter, although only 15% will survive the first year. Young rabbits are quickly and can survive on their own after a few weeks. They become sexually mature in approximately 2-3 months, so the population can grow very quickly.
