Questions related to Bison
How can we know, that european bison had been completely free ranging in ancient and medieval times ?
Maybe there existed a kind of husbandry, comparable to rendeer culture or to the supplementary feeding that helped to keep populations alive in medieval and newer centuries in Bialowieza forest even before in Holocene timescales.
Are there any hints in archeological remains for that ?
The carnivorous dimetrodon and the herbivorous edaphosaurus were both Permian period tetrapods with rows of vertical spikes sticking straight up from their backbones. Illustrations show these bones with a thin membrane stretched over them and call it a "sail." It was thought that this structure was for thermoregulation, but this hypothesis has now been fairly thoroughly debunked. So what was it for?
There is a modern animal with a similar structure: the American bison. The bison's hump has bones in it because (unlike the fatty hump of a camel), it houses powerful muscles that allow the bison to swing its massive head from side to side. Its head functions as a snowplow so the bison can get at grass that is buried under a meter or more of snow.
I propose that the edaphosaurus filled the same ecological niche as the bison. It lived on prairie grasslands that got a lot of snow in the winter. That's not a sail, it's a hump!
Dimetrodon means "two measures of teeth" because it was the first animal to have longer teeth at the front of its mouth, somewhat like the canines in carnivorous mammals. I propose that dimetrodon used its long front teeth to grab prey animals and then it used the muscles in its hump to swing its prey from side to side with such force that it snapped the poor animal's neck.
I have a colleague that has ammassed impressive knowledge and collections of Pleistocene Bovivni from North America. Who can I put him in touch with to sample these 'sub-fossils'?
I am using BISON, a web service that gives public GIS information, and they recently added citizen science mapping of various invasive species to their site. I am wanting to use the BISON data to analyze an invasive species prominent in Tennessee. However I am wanting to compare the accuracy of this citizen science to another map, though I am not sure which direction to go about finding this other map to compare and remotely sense the specific invasive species I am looking for. I am also wanting to look at taking a different direction with the BISON data and seeing if I can analysis a pattern of early detection in the species, but not sure how I can use GIS to do that specifically. The problem is that I figure I try to see if I can remotely sense this data all while being in a different state than Tennessee. A push in the right direction would greatly be appreciated.
Late morulas or early blastocysts washed out of the European bison cow's uterus transferred into the uterus of the synchronised Domestic cows.
I'm actually going to work on the diet and the bacteria present in the gastrointestinal tract of wild Asian elephants, using NGS (16s rRNA for bacteria and trnL for plants) on fecal samples. I'm therefore looking for an extraction kit that would work on feces and able to extract plant DNA and bacterial DNA as well.
I'm already aware of several research groups using :
- PowerSoil htp 96 well Soil DNA Isolation kit : Bergmann et al. 2015 - Seasonal Shifts in Diet and Gut Microbiota of the American Bison (Bison bison) and Metcalf et al. 2017 - Evaluating the impact of domestication and captivity on the horse gut microbiome.
- Zymo XpeditionSoil/Fecal DNA mini kit: Kartzinel et al. 2019 - Covariation of diet and gut microbiome in African megafauna.
Does anyone use these kits for the same purpose? Does anyone would recommend other kits?
Thank you !
I am doing a GWAS analysis of european bison's a dog's SNPs. Right now I am doing multiple data clean up, according to previous studies and what I have learned.
I was thinking, if it is ok to test HWE and discard data that does not fit if I am working with animals, where mating is controlled and inbreeding coefficient is high?
And what about tests for population structure etc.? It is obvious that there is going to be some structure in reintroduced and domestic animals. I don't want to loose any important data and I want to be sure, that I have done everything correctly.
Thank you for your help.
In compiler construction, do I need different tools like YACC, LEX, BISON etc to develop each of the six stages/phases (Lexical Analysis, Syntax Analysis, Sematic Analysis etc) of the compiler?
Or Can I use only one of these tools, YACC, LEX or BISON to develop a full mini compiler.
This project uses GBIF, BISON, EDDMapS, and other sources with data available through APIs to keep the information current. I'm always curious about updating my scripts with new information. So, I wonder what species occurrence databases do others frequently use?
I've been looking into the BIEN data but haven't really cracked the book all the way open.
Water Buffalo (Bubalus bubalis) meat in the tropics is becoming more sought after. It is commonly called Bison. however, the American “buffalo” are actually bison. Scientifically, Bison bison. The only true buffalo are the Asian water buffalo and the African buffalo. The American bison are actually very closely related to the Wisent, which are European bison. The American bison (Bison bison) lives only in North America, while the two main buffalo species reside in Africa, Asia, South America, Canada and the Caribbean.
“Archaeological monitoring associated with the recent Walterdale Bridge replacement project also identified several deeply buried intact archaeological sites of high significance, including precontact Aboriginal campsites ranging in age from 1200 to 1500 years old to more recent historic pit features dating to the fur trade era (early 1800s) and representing the earliest historic archaeological sites in Edmonton outside the palisades of Fort Edmonton.” Corespondence on January 19, 2018 from Caroline Hudecek-Cuffe, PhD Parklands Archaeologist (Acting)

All along the river are tell tale signs of flow path of the once a continental ice sheet. Bison bones and wood pieces protrude as well as organic debris according to Edmonton Geological society as far back as 8000 BP. Edmonton Beneath our Feet 1993 p. 116.
I also want to include that the rocks from volcanic eruptions in the past may have been carried via the fur trade which could also have been done by fur traders and also if there is trade with Cree or other Indigenous peoples there is evidence then and the degree to how far tools and these stones where taken is of interest I believe. Stories such as those from historian J. G. Macgregor and his book of Anthony Henday and the first white man to enter Alberta (Edmonton, 1954). “The Saskatchewan river abounds in petrified woods... of many types and colors but the Indian seem to have a liking for the beautiful red specimens (obsidian from Idaho and Yellowstone) and their old campsites are littered with pieces carried up from the river several scrapers and knives which are made of this material I found lying around.“ P232

I wondered if anyone has developed field protocols for biopsy darting that would be relevant to sampling bison? I found a few papers with some insights, but would like to offer experienced field tips and guidance (not typically detailed in papers) for field crews that will be collecting samples for genetic analyses from 4-5 bison herds. Thanks!
I'm looking for aDNA studies on the phylogeny of European bison (Bison bonasus). Preferably both mtDNA and Y-chromosome studies. Does anyone know of such studies having been published?
