Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

The Anatomical Record, Volume 309, Issue 7, Page 1713-1748, July 2026.
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Beavers, Castor canadensis, Feeding on Salmon Carcasses: Opportunistic Use of a Seasonally Superabundant Food Source [PDF]

, 2005
We report observations of Beavers (Castor canadensis) foraging and feeding on discarded Chinook Salmon (Oncorhynchus tshawytscha) carcasses within the confines of the Susitna River drainage in southcentral Alaska on three separate occasions between 1999 ...

Movement characteristics of American beavers (Castor canadensis)

Behaviour, 2014
Physiological states and foraging behaviors may shape movement patterns of animals. Optimal foraging theory and what we term the deliberate movement hypothesis predict that, to reduce predation risk, central place foragers should move faster with smaller turning angles the further they are from their central place.

Ecosystem Engineers at Work: How Beaver Ponds Reshape Avian Abundance and Diversity in a Mountainous Forest Ecosystem in Central Europe

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Eurasian beavers significantly enhance bird diversity and abundance by creating wetland habitats, with 23% higher bird numbers and more unique species at beaver ponds compared to unaffected streams. The size of water surfaces was the key factor influencing species richness, particularly benefiting birds that rely on aquatic environments.

Stream Temperature Variability in Headwater Beaver Dam Complexes in Relation to Hydrologic and Environmental Factors

Ecohydrology, Volume 19, Issue 5, July/August 2026.
ABSTRACT Beaver modify hydrological regimes and have the ability to both increase water storage and alter stream temperatures. For these reasons, beaver translocation and the construction of human engineered beaver‐dam analogues (BDAs) have become popular tools for climate‐change adaptation.

Knowing for controlling: ecological effects of invasive vertebrates in Tierra del Fuego Conocer para controlar: efectos ecológicos de vertebrados invasores en Tierra del Fuego

Revista Chilena de Historia Natural, 2008
The Tierra del Fuego (TDF) archipelago is recognized as part o the last places on Earth that may still be considered wild. However, this condition may be threatened by the large number of invasive species present on the archipelago.

eDNA sampling reveals no evidence of negative effects of beaver recolonisation on the catchment‐scale distribution of migratory fish

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
This study provides novel insights into the catchment‐scale co‐distribution of beavers and migratory fish, and there was no evidence of negative effects on the catchment‐scale distribution of migratory fish species. More generally, this study highlights how catchment‐wide eDNA monitoring can be applied by environmental managers to aid decision‐making ...

Origin of the invasive North American beaver (Castor canadensis) sampled in Western Europe [PDF]

International audienceThe North American beaver (Castor canadensis) has been introduced in Western Europe since 2006. Its occurrence has been recorded in Luxembourg, Rhineland-Palatinate (Germany) and Wallonia (Belgium).

Persistent paramesonephric ducts (masculine uterus) in the male North American beaver (Castor canadensis) [PDF]

, 1998
Remnants of the paramesonephric (Müllerian) ducts can be found in the male as a uterus-like structure. Historically, these have been known as a masculine uterus. We examined the reproductive tracts of 24 male North American beaver, Castor canadensis Kuhl,
