Reintroduced Eurasian beavers (Castor fiber): colonization and range expansion across human-dominated landscapes

Published by: Biodiversity and Conservation

18th March 2017

This paper used a computer models to predict where beavers would be likely to live in Flanders, Belgium. The paper highlights which factors are important for beaver settlement, including distance to water and availability of certain tree species. At identified locations, additional monitoring could help to identify and manage potential conflicts early on, ensuring a more peaceful coexistence between humans and beavers.

Identification of differentially expressed placental transcripts during multiple gestations in the Eurasian beaver (Castor fiber L.)

Published by: Reproduction, Fertility and Development

14th February 2017

This technical genetics study examined gene activation in Eurasian beavers. Specifically, it looked at genes related to the placenta during pregancies. 124 genes were identified which were activated in different ways depending on whether beavers were carrying twins or triplets. Understanding these genes can aid in beaver conservation efforts. Please note, this resource is not open-access.

De Novo Genome and Transcriptome Assembly of the Canadian Beaver (Castor canadensis)

Published by: G3: Genes, Genomes, Genetics

1st February 2017

This text reports on the process undertaken to create the first decoded genome of a North American beaver. The text explains the different technologies it used. The output was deemed to be useful for future beaver and broader genetic research. It also revealed a lot of genes related to tooth development and arrangement, which makes sense for beavers!

A specific small game exploitation for Lower Paleolithic: The beaver (Castor fiber) exploitation at the Caune de l’Arago (Pyrénées-Orientales, France)

Published by: Journal of Archaeological Science: Reports

1st February 2017

In France, archaeologists found beaver bones with fascinating implications. The bones had cut-marks indicating meat removal and skinning. This shows that Homo erectus was eating beavers during the Ice Age - while this seems like it may have been opportunistic, such bones were found on multiple levels of the cave system, suggesting it wasn't that rare. This highlights the varied meat resources used by our human ancestors beyond large mammals. Please note, this resource is not open-access.

When to leave: the timing of natal dispersal in a large, monogamous rodent, the Eurasian beaver

Published by: Animal Behaviour

31st January 2017

This study followed beavers across 3 Norwegian rivers for 18 years to understand when they left home. Only 9% of beavers never left their birth family, with most leaving at 3.5 years old and some only at 7 years old. When their same-sex parent was older, young beavers tended to delay their dispersal, possibly to take over the territory. Lower population density surrounding the birth home made beavers more likely to disperse when they're younger.
