Another wonderful article about our bison research. We are very proud to have have multiple calves born in consecutive years from our efforts. #bison #wildlife #conservation #research #usask #reproduction

[WCVM Today @WCVMToday]

Second-year veterinary student Ella Macquisten spent a day chronicling the work of a #WCVM research team working toward conserving the world’s wild bison population. Read more: https://t.co/Tp8VhAl8zg @usaskUGResearch @usask @vpieusask #woodbison #bisonresearch

Another exciting year working with the wood bison at the Toronto Zoo! 🦬🔬❤️ #bison #wildlife #conservation #research

We are excited to announce that four of our wood bison are pregnant as part of a year-long reproductive study for this threatened species! 🦬🔬 Read more: https://t.co/7iSvyJ1vdW #savingspecies

The ferrets have landed🐾

Since 1993, 400+ Toronto-born endangered black-footed ferrets have been released to the wild. And thanks to @LightHawk_org, 21 more ferrets made the journey to the US Fish & Wildlife National Black-footed Ferret Conservation Centre in Colorado this week

It’s #NationalBisonDay! Did you know that the Zoo has been involved in wood bison conservation since 1977? Learn more: https://t.co/c4dVPRPsYc

Some elephants no longer grow tusks as a result of natural selection from ivory poachers. It is sad but interesting to see such quick changes as a result of human caused damage. https://t.co/xxhvc74hFI

Eric will be speaking about some of the cool things we are doing with bison conservation! #bison #wildlife #conservation #reproduction

[The Toronto Zoo @TheTorontoZoo]

Join us for a Research Symposium webinar with @MitacsCanada on Monday, August 23rd from 9-10am EST. You'll learn about various animal research and technologies from Dr. Gabriela Mastromonaco, Dr. Jenna Congdon, and Dr. Eric Zwiefelhofer. For details, visit https://t.co/lmNVP8EvVA

After countless hours of hard work at the farm and the lab, it is very rewarding to have happy and healthy Wood Bison calves on the ground that are a result of frozen IVF embryos. Great work team! @ericzwief @usask

Researchers at the @LFCE_usask are welcoming Skeeter and Mo to their bison population. The two male calves mark a significant achievement in developing a diverse germplasm biobank. @InnovationCA https://t.co/LSi1lPPpbs

[SDSU College of Ag, Food & Environmental Sciences @SDStateCAFES]

The SDState @BisonCOE has approved eight research projects to study topics ranging from ecosystem impact to meat quality.

The center awarded more than $300,000 in funding to support the first year of each project.

Researchers were able to use artificial insemination to bring 97 hatchling whitespotted bamboo sharks to life, according to a paper published in @SciReports. https://t.co/hqHtZDowP1

@MilesParisi @FattebertJ They are in a commercial bison farmers field. In the wild and in conservation herds they would be maintained in separate herds.

I happened upon this prime example of the morphological differences between Wood bison (on left) and Plains bison (on right). #bison #subspecies

A few differences include:
1⃣Hump shape (square vs rounded)
2⃣Forehead hair (long and straight vs fuzzy)
3⃣Chap hair (short vs long)

[Miranda Zwiefelhofer @Miranda_Zw]

@YRBisonRanch @ericzwief Awesome! Do you notice any behavioral differences between them? In a stand off - who is tougher?

[Miranda Zwiefelhofer @Miranda_Zw]

Eric Zwiefelhofer @ericzwief and I were asked to write a guest blog for Buffalo Tales and Trails on "Assisted Reproduction in Bison". Check it out!

Busy week in the IVF lab! Here are some cattle IVF embryos produced in my quality control run. Gearing up for lots of bison oocyte collections and IVF runs this summer! @ericzwief @usask @WCVMToday #embryos #research #reprorocks #phd
