Highland springs, north Iceland.

Underground streams break out from underneath leaky strata. In this case ice-age moraines, but in others lavafields.

The springs harbour live and the underground rivers have microorganisms and top predator in small freshwater amphipods

Only endemic invertebrates in iceland, that have lived through couple of Ice-ages (>5 million years)

Contrary to expectations based on #phylogeography (topleft, blue boxes) or habitat similarity (red boxes), undisturbed communicative behavior was more similar between the more distant S. consobrinus and S. u. undulatus, than between S. u. hyacinthinus and either of those two, suggesting that behavioral plasticity and local adaptation to different selective pressures in each population underlie interpopulation variation in behavior.

"Sixty-three skeletons from the Pre Pottery Neolithic B (PPNB) sites of Tell Halula, Tell Ramad and Dja'de El Mughara dating between 8,700–6,600 cal. B.C. were analyzed, and 15 validated mitochondrial DNA profiles were recovered. In order to estimate the demographic contribution of the first farmers to both Central European and Western Mediterranean Neolithic cultures, haplotype and haplogroup diversities in the PPNB sample were compared using phylogeographic and population genetic analyses to available ancient DNA data from human remains belonging to the Linearbandkeramik-Alföldi Vonaldiszes Kerámia and Cardial/Epicardial cultures."

🌘 Fermat's Library | 早期馬匹傳入大平原和北洛磯山脈的研究
➤ 結合基因、同位素、放射性碳和古病理學證據的跨學科研究
✤ https://fermatslibrary.com/s/early-dispersal-of-domestic-horses-into-the-great-plains-and-northern-rockies
這篇研究結合了基因、同位素、放射性碳和古病理學證據，對歷史考古馬匹遺骸進行了跨學科研究。研究發現，現代北美洲馬匹與伊比利亞馬匹有著很強的遺傳親緣關係，後來又有來自英國的馬匹傳入，但沒有維京人的痕跡。馬匹從南部迅速傳播到北洛磯山脈和中部平原，可能是通過原住民的交流網絡實現的。在18世紀歐洲觀察者到來之前，馬匹已經深深地融入了原住民社會，反映在牧群管理、儀式實踐和文化中。這篇研究對西部北美洲的社會和生態變革做出了貢獻，但這一轉變的機制和時間仍不清楚。
+ 這篇研究提供了有關早期馬匹在北美洲傳播和融入原住民社會的新見解。跨學科的方法和多種證據的結合使得研究更加全面和可靠

Hmm.. What about directly identifying the homeland? We used #phylogeography to infer the most probable origin of these languages.

It turns out the most probable homeland matches the Northern Origin scenario, not the Ancient or Southern scenarios.

Aus aktuellem Anlaß, got a paper on Fagus hayatae (#beech) #phylogeography published 2016 in Ecol. Evol. with potentially interesting data, which is nowhere to be found.

Missing here but should be obligatory following each "Conclusion" section: a section on "Data availability". With a link to the phylogenetic matrix, ideally.

#OldPosts D. Morrison and I and why We want to publish our phylogenetic #data – including networks, but where?—https://phylonetworks.blogspot.com/2018/02/we-want-to-publish-our-phylogenetic.html

(Since I messed up the server thing but am now on ecoevo social, a new #Introduction)

Hi, I'm Emily. I'm an Assist Prof in Biology at the University of Memphis.

My main interest is linking #phenotype to #genotype in wildlife; then explaining geographic patterns through #phylogeography, #popgen, and #demography. My focal species is the American black #bear, with secondary projects in #chipmunks, #rats, and #polarbears.

Registrations open for the 15th International #Symposium on #Flatworm Biology (24-28 July 2023, CEBIMar, São Sebastião, #Brazil): https://www.even3.com.br/xvisfb/

Presentations on the #biology and #evolution of #flatworms are invited including #taxonomy, #systematics, #phylogeny, #morphology, #naturalhistory, #ecology, #cellularbiology, #molecularbiology and #molecular studies of #regeneration, #aging, #bioadhesion, #endemism, #phylogeography, #developmentalbiology with #model species #platyhelminths ´

J'avais raté le dernier episode de cette fantastique série :

"Pleistocene origins, western ghost lineages, and the emerging phylogeographic history of the red wolf and coyote".

I'm an Evolutionary Biologist, currently working as an assistant researcher (CONICET 🇦🇷). I am interested in both, theoretical and empirical work 🦎 🐠 🐜 🕷️ related to #phylogenetics #phylogeography #biogeography & #genomics. Love that we have up to 500 characters on Mastodon 😅

An #Introduction:

I'm the #Curator of #Herpetology at the #NaturalHistoryMuseum of #Denmark, and #AsstProf of #Vertebrate #Zoology at the University of Copenhagen.

I work in evolutionary and systematic herpetology, working on a variety of topics including #museomics, #macroevolution, #convergence, #phylogeography, #speciation, #systematics, and #taxonomy. I mostly work on the #amphibians and #reptiles of #Madagascar. #Miniaturisation is my jam.

#introduction
Hi everyone! 👋 First time I'm tooting!
I'm an Italian #entomologist doing my #PhD at the Institute of Evolutionary Biology #IBE in Barcelona.

I study the #diversity and #evolution of the European #ant fauna using #IntegrativeTaxonomy, #genetics (mainly #barcoding), and #genomics (#UCEs). I also work on #InvasiveAlienSpecies and #butterfly #phylogeography.

I love beer, #Rstats, maps, and turning over stones. Ah, I'm also an #iNaturalist addict!

@naturepoker #OxfordNanopore is my favorite website for window-shopping! Do you have an estimate of how much it would cost per plastid? Would be interesting for plant #phylogeography and #conservation
