Dispersal Patterns of San Joaquin Kit Foxes (Vulpes macrotis mutica) [PDF]

open access: yesJournal of Mammalogy, 2000
We investigated dispersal patterns of San Joaquin kit foxes (Vulpes macrotis mutica )o n the Naval Petroleum Reserves, California. Of 209 juvenile kit foxes monitored during 1980‐1996, 33% dispersed from their natal territory. Significantly more males (49.4%) than females (23.8%) dispersed, and dispersal peaked in July.

Highly and Lowly Domesticated Endangered Fish From a Conservation Hatchery Diverge in Their Thermal Physiology, Transcriptome, and Methylome [PDF]

open access: yesEvol Appl
ABSTRACT Conservation hatcheries aim to produce fish for supplementation of wild populations, but hatchery environments may drive phenotypic divergence from wild fish. These diverged traits may have reduced fitness in the wild, which could compromise wild population sustainability and evolutionary potential, such as in response to climate change. Delta

Competitive Interactions between Coyotes and San Joaquin Kit Foxes [PDF]

open access: yesJournal of Mammalogy, 1998
Competitive interactions between coyotes ( Canis latrans ) and federally endangered San Joaquin kit foxes ( Vulpes macrotis mutica ) were investigated at the Naval Petroleum Reserves in California (NPRC) during 1984–1995. Coyotes and kit foxes used similar food items, indicating the potential for exploitative competition. Leporids were the primary prey

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 ...

Consequences of Lack of Parameterization Invariance of Non-informative Bayesian Analysis for Wildlife Management: Survival of San Joaquin Kit Fox and Declines in Amphibian Populations

open access: yesFrontiers in Ecology and Evolution, 2020
Computational convenience has led to widespread use of Bayesian inference with vague or flat priors to analyze statistical models in ecology. Vague priors are claimed to be objective and to “let the data speak.” However, statisticians have long disputed ...

Management and Conservation of San Joaquin Kit Foxes in Urban Environments [PDF]

open access: yesProceedings of the Vertebrate Pest Conference, 2012
Author(s): Cypher, Brian L.; Van Horn Job, Christine L. | Abstract: The San Joaquin kit fox is listed as federally Endangered and California Threatened, primarily due to habitat loss from agricultural, industrial, and urban developments. However, a population of kit foxes estimated at 200-400 persists within the city of Bakersfield, CA. This population

Assessment of Abundance of San Joaquin Kit Foxes by Spotlight Surveys [PDF]

open access: yesJournal of Mammalogy, 1997
Biologists of the California Department of Fish and Game have conducted quarterly spotlight surveys of San Joaquin kit foxes, Vulpes macrotis mutica , and potential species of prey along seven 48-km routes since 1970. The annual reproductive cycle of the foxes was reflected by a seasonal cycle in the counts.

Predicting Wildfire Damage Versus Habitat Compatibility In Endangered San Joaquin Kit Foxes

open access: yesJournal of Student Research, 2022
Current research on this topic covers a large portion of external forces acting on the habitat of the endangered San Joaquin Kit Fox (SJKF). In spite of this, no sources currently exist which directly correlate fire damage with a SJKF ecosystem model.

Ontogeny influences sensitivity to climate change stressors in an endangered fish. [PDF]

open access: yes, 2014
Coastal ecosystems are among the most human-impacted habitats globally, and their management is often critically linked to recovery of declining native species.
