Assessing the role of dens in the spread, establishment and persistence of sarcoptic mange in an endangered canid

open access: yesEpidemics, 2019
Sarcoptic mange is a skin disease caused by the mite Sarcoptes scabiei that can devastate populations of wild species. S. scabiei can survive off-host and remain infective for specific periods.

Mechanisms of selenomethionine developmental toxicity and the impacts of combined hypersaline conditions on Japanese medaka (Oryzias latipes). [PDF]

open access: yes, 2014
Selenium (Se) is an essential micronutrient that can cause embryotoxicty at levels 7-30 times above essential concentrations. Exposure to hypersaline conditions and 50 μM selenomethionine (SeMet) decreased embryo hatch and depleted glutathione in ...

USE OF AGRICULTURAL LANDS BY SAN JOAQUIN KIT FOXES

open access: yesWestern North American Naturalist, 2007
Although the current range of the endangered San Joaquin kit fox (Vulpes macrotis mutica) borders large areas of farmland, the ecology of this species rarely has been studied within an agricultural setting. In central California, we examined habitat use, prey availability, and diet of radio-collared kit foxes inhabiting an aqueduct right-of-way (ROW ...

Advancing Recovery of Endangered San Joaquin Kit Foxes Through Urban Rewilding [PDF]

open access: yes
San Joaquin kit foxes (Vulpes macrotis mutica) are endemic to arid habitats in the San Joaquin Valley region of central California. This species is listed as Endangered due to profound habitat loss throughout its range caused by agricultural, industrial,

Anticoagulant rodenticides on our public and community lands: spatial distribution of exposure and poisoning of a rare forest carnivore. [PDF]

open access: yes, 2012
Anticoagulant rodenticide (AR) poisoning has emerged as a significant concern for conservation and management of non-target wildlife. The purpose for these toxicants is to suppress pest populations in agricultural or urban settings.

Rapid generation of prion disease models using AAV‐delivered PrP variants in knockout mice

open access: yesBrain Pathology, EarlyView.
We developed a rapid AAV‐based system to generate prion disease models in weeks rather than months. Following systemic AAV9P31 delivery of modified PrP to knockout mice, we achieved brain‐wide expression and successful propagation of both classical (RML) and atypical (GSS‐A117V) prion strains.

Scat DNA Applications for Low‐Density Carnivore Survey: Techniques, Efficiency and Future Directions

open access: yesMammal Review, Volume 56, Issue 1, March 2026.
We reviewed 338 studies encompassing mostly Felidae, Canidae and Mustelidae species throughout the world, confirming scat DNA as a reliable genetic source for many applications. The findings here offer guidance for future studies on low‐density carnivores, helping to design cost‐effective research and improving data quality for conservation efforts ...
