My latest photo project is about #macros in the #goldenhour of an #urban #park in #Berlin. Correspondingly, my latest YouTube photo publication shows the #lichen #Xanthoria #parietina (#Teloschistaceae), which is associated with #algae of #genus #Trebouxia. The yellow color of the ecologically tolerant lichen is due to the anthrachinone #parietin.

Since the #scientificname of a #species consists of two main components—#genus and #epitheton—#taxonomists describing #newspecies regularly face the question: what should I name my species after? Personally, I prefer an ecological characterization of the species via its #epithet. But scientists/celebrities are also frequently honored. The fact that it was now even an entire #televisionseries is a great anecdote, but has strict reference to nature work (BBC#BluePlanet)

@plazi_species very interesting work about the #tarantula genus #Aenigmarachne (#Theraphosidae), formerly monotypic with a species known from Costa Rica, now with a #newspecies described from both genders and discovered in #Colombia, thus extending the former known range of the #genus.

Shown is a #fly of the #genus #Sarcophaga, not being determined on a #specieslevel. It belongs to the #cryptic S. carnaria-#speciesgroup S. #carnaria itself is distributed throughout the #Palearctic region and is a #parasitoid of earthworms. H. E. Moore et al. (2021) used #cuticularhydrocarbon (CHC) profiles to differentiate 11 Sarcophaga species (including S. carnaria) from each other

Ach, ich find's schon schade, wenn sich heute Leute dafür feiern, dass sie #Genus und #Sexus verwechseln. 😞

"[...] schon vor 300 Jahren fiel den Sprechenden und Schreibenden auf, wie unlogisch, irreführend, ja ausgrenzend und ungerecht die deutsche Sprache teilweise verfährt. Mit seinen gleich drei Geschlechtern ist das Deutsche eine bis in sein Genom ‚gegenderte‘ Sprache und kann vielleicht schon rein grammatikalisch nie alle meinen. Aber schon im 18. Jahrhundert griff man verändernd ein und hatte die Absicht, wenigstens auf hohem Niveau zu scheitern." 🙂 🙃

Open access article, and the "non-technical summary" section near the beginning gives an overview everyone can understand. 🧪🦖

https://www.cambridge.org/core/journals/journal-of-paleontology/article/troodontid-specimens-from-the-cretaceous-two-medicine-formation-of-montana-usa-and-the-validity-of-troodon-formosus/3E58F1FDA3FE53DE569E0D0B20E79F22

Very short version: #Troodon was considered a valid #genus for well over a century, until it was merged with #Stenonychosaurus about a decade ago, and due to specimen quality Stenonychosaurus took priority. Now careful examination indicates Troodon is a valid genus again.

This process is familiar from other famous #dinosaur genera, most notably #Brontosaurus and #Apatosaurus. Even *living* animals are hard to classify a lot of the time; nothing between #kingdom and #species is really set in stone. The tension between "#lumpers" and "#splitters" never ends.

Troodon is special. Maybe it was intelligent, in a way we'd recognize as such, and maybe it wasn't. But it was almost surely *smart*, and quite possibly social, and likely an omnivore. Does that remind you of anyone?

Maybe I'm fooling myself, when I feel a kinship across deep time. And maybe I'm not.

The #Kingvulture #Sarcoramphus papa (#Cathartidae) is distributed from southern Mexico to large parts of #SouthAmerica. The strikingly #colorful species is the only representative of its #genus. It hunts smaller vertebrates and prefers carrion. At #carrion sites they successfully drive away other vultures. Usually only one egg is incubated, which is deposited in a tree holes etc.; no nest is built.

Der erste namentlich bekannte Dichter ist die Dichterin En-Edu-Ana.

#Genus und #Sexus des selben Wortes in einem Satz - wer kommt heute noch damit klar?

(Wäre nur von der ersten Dichterin die Rede, wüsste man nicht ob frühere männliche Dichter bekannt sind.)

Eines der sonderbaren #Kofferworte hörte ich heute beim Discounter. Ich war versucht, den #Genus zu korrigieren nach maskulin:

„ meinen Morgenlatte …”

Deitsches Sprak sein schwärres Sprak.

The surprisingly connected origins of "knee" and "genuine". https://youtube.com/shorts/K4LW4sxjIaw

#Troodon may once again be a valid #genus. Or, uh, so I’ve heard.

#Brontosaurus is smiling, and #Diatryma is waiting patiently.

ICYMI, meine #Doktorarbeit, „Genusresolution bei mittelhochdeutsch beide“, wurde vor kurzem veröffentlicht 📚📕 ICYMI, my #PhDthesis, “[Gender resolution of Middle High German beide ‘both’]”, has recently been published:

“For example, there’s a good argument to be made that #humans, #chimpanzees, and #bonobos all belong together in one #genus, either #Pan or #Homo. It’s only our desire to see ourselves as something special that causes us to put them in one genus and us in another. If #ravens—probably the smartest living #dinosaurs, although some #parrots give them a run for their money—were building a #taxonomy, they’d undoubtedly lump us together with our close relatives. But they might go to great lengths to separate themselves from #crows!”

I like to think I can still turn a nice phrase now and then.

#Fossil found on the side of the road is a new #species of #mosasaur
In 2015, Deborah Shepherd notified a park ranger about an exposed fossil. That ranger notified ND Department of Mineral Resources. Her actions led to discovery of what scientists say is not only a new species, but an entirely new #genus of mosasaur, a giant marine predator from #Cretaceous seas. Bite marks preserved on fossil suggest that it met its end at the hands—or rather teeth—of another mosasaur.

#Pilze gibt es ja tatsächlich in allen nur denkbaren Erscheinungsformen, wie dieses hübsche 😄 Beispiel aus der #Gattung der #Gallertbecher zeigt.

Fleischrote Gallertbecher - Purple Jellydisc
Ascocoryne sarcoides

#Mushrooms do indeed exist in all conceivable forms, as this pretty 😄 example from the mushroom #genus of the #jellycup shows.

"It is an exceptional #discovery as it is one of the most colorful #species in the #genus #Tylototriton . This is also the first time that a #crocodile #newt species is recorded from the Central Highlands of #Vietnam . Occurring at elevations from 1,800 to 2,300 m above sea level, this discovery sets an elevational record for the genus in the country, with former distribution ranges between 250 m and 1,740 m," says #discoverer and first author of the study Trung My Phung.

Does anyone have some guidance to offer on using #hashtags with #BinomialNomenclature? What should I prefer: a single hashtag of #GenusSpecies, two separate hashtags for #Genus and #species, or something else?

Continuing down this path, what should I consider when writing a hashtag indicating a selected form like Rhododendron davidsonianum 'Ruth Lyons' or indicating the epitaph refers to a hybrid such as Rhododendron 'Unique'?

We are very happy to learn that our paper was the 5th most cited among the ones published on #GENUS during the last three years. This was a collective effort led by @ecamposlima with colleagues from different Latin American countries.

#FossilAdventCalendar Day 17

This #whale-sized #marine #reptile in the #RoyalTyrrellMuseum is the #ichthyosaur Shastasaurus sikkaniensis. Unusually, it was not only one of the earliest members of its group, but one of the very largest. Its #species name comes from where it was found, along the Sikanni Chief River which flows out of the #RockyMountains of #BritishColumbia 🇨🇦. Its #genus name comes from Mt. #Shasta in the #CascadeRange, where other species of this Triassic titan have been found.

One of the great #mathematicians of the theory of integrable systems has passed away: Igor #Krichever (1950-2022) was instrumental in developing algebro-geometric methods to construct higher #genus solutions of #soliton equations 👉🏼 https://www.math.columbia.edu/~woit/wordpress/?p=13200 .
