Chromosomal assembly and comparative analysis of the red fox (Vulpes vulpes) genome
… species for the Genome 10K Project is the red fox (Vulpes vulpes), and specifically a fox from an experimental breeding project in which silver foxes (a melanistic variant of the red fox) have been selected over the past several decades to exhibit extreme behavioral phenotypes. The …

Signatures of selection in the red fox (Vulpes vulpes) in Europe using genotype-by-sequencing
… selective pressures that may be seen in the red fox’s genome. Additionally, debate continues to whether red foxes remained in isolated refugia or existed as a continuous population in southern Europe. Regardless, previous studies highlight the importance of refugia of the Last Glacial Maximum …

Thermoregulation by foxes
… control system which could be used to predict the responses of unrestrained foxes of different species to naturally occurring thermal stress. The studied species included the red fox (Vulpes vulpes), arctic fox (Alopex lagopus), and kit fox (Vulpes macrotis). The model was used to test …

INDIRECT EFFECTS OF LOW AMPLITUDE ARVICOLINE CYCLES ON DAILY NEST SURVIVAL OF DUNLIN (CALIDRIS ALPINA HUDSONIA) IN A RAPIDLY CHANGING CLIMATE
… Alternative Prey Hypothesis (APH) states that predators switch to relatively more abundant prey when their main prey is scarce. Arctic lemming population cycles may indirectly affect predation risk on alternative prey such as shorebird nests as they share predators. I examined the indirect …

Red fox genome assembly identifies genomic regions associated with tame and aggressive behaviors
Strains of red fox (Vulpes vulpes) with markedly different behavioral phenotypes have been developed in the famous long-term selective breeding program known as the Russian farm-fox experiment. Here we sequenced and assembled the red fox genome and re-sequenced a subset of foxes from the tame, …

Home Range, Home Range Expansion, Dispersal, and Mortality of Juvenile Red Foxes in Southeastern South Dakota
… from aerial and landowner surveys showed that red fox (Vulpes vulpes) families on the Sinai study area decreased from 13 (5.2 per township) in 1976 to 11 (4.4 per township) in 1977. The majority (88%) of the active red fox dens was located in pastures and idle lands although these cover types …

Use of restored grasslands by mammals in a dynamic agroecosystem: insights from camera trapping
… winter) to assess mammal responses on 30 restored grassland sites in a dynamic agroecosystem in Illinois from 2014 to 2015. I tested hypotheses about the effects of local habitat conditions and landscape context on use of restored grasslands by four focal species: raccoons (Procyon lotor), …

Aspects of Mammalian Predation on Upland Nesting Waterfowl in Central North Dakota
<p>The impact of mammalian predation on upland nesting waterfowl was studied in central- North Dakota during the summers of 1987 and 1988. Survival of artificial nests was examined in relation to nest density, vegetation cover, distance from roads, active predator dens, and other artificial nests …

Assessing the Effects of Sea-Level Rise on Piping Plover (Charadrius Melodus) Nesting Habitat, and the Ecology of a Key Mammalian Shorebird Predator, on Assateague Island
… and is highly vulnerable to habitat change and predation. We have addressed these two threats by 1) developing and implementing a linked model system that predicts future change to piping plover habitat resulting from sea-level rise and beach management efforts by joining dynamic models of …

Estimation of Predator Densities in Western South Dakota
Evaluation of methods for predator density estimation is necessary to assess biases in techniques and determine those best suited to local conditions. Knowledge of predator populations allow wildlife managers to prescribe and assess management and control activities. Objectives of this study were …

Genomic response to selection for behavior
The red fox (Vulpes vulpes) is a model of significant interest to social behavior genomics because of an experimental breeding project that began in the mid-20th century at the Institute for Cytology and Genetics in Novosibirsk, Russia. In this experiment, foxes acquired from fox farms were bred …

An Investigation of patterns of mammalian scavenging in relation to vertebrate skeletal remains in a Northwestern European context: forensic applications.
… species found within Northwestern Europe. The red fox (Vulpes vulpes) and Eurasian badger (Meles meles) are the largest wild mammalian scavenger species inhabiting peri-urban and rural environments within Northwestern Europe. These mammalian scavengers have dentitions and bite forces capable of …

Factors Influencing Use of Fecal Line Surveys For Estimating Trends in Predator Populations in Western South Dakota
… relative densities of coyote (Canis latrans), red fox (Vulpes vulpes), and striped skunk (Mephitis mephitis) populations is necessary to monitor population changes in western South Dakota. Fecal line surveys were used to estimate relative densities because they are easy to use, inexpensive, do …

Piping plover habitat and demography following storm-induced and engineered landscape change
… melodus) are federally threatened and endangered, disturbance-dependent shorebirds, nesting on broad, sparsely vegetated beaches, sandbars, and lakeshores. In October 2012, Hurricane Sandy storm surges cleared vegetation and opened old and new inlets through Fire Island and Westhampton Island, …

Causes and Implications of Fox Population Dynamics in Central Southern England
The red fox (Vulpes vulpes) is a generalist mesopredator and the world’s most widespread terrestrial carnivore. As a major predator of game, livestock, and wildlife, foxes are culled throughout their range to limit their impact, including in the UK, where data suggests they occur at higher overall …
