Abstract To identify activity patterns and distribution of gray foxes (Urocyon cinereoargenteus) in chaparral and sage-scrub habitat in southern California, we used radiotelemetry to monitor 18 foxes during May 1997–April 1999. For comparison, we used simultaneously collected telemetry data on sympatric coyotes (Canis latrans) and bobcats (Lynx rufus). Gray foxes mainly were crepuscular and nocturnal with a daily activity rate of 60% in the summer dry season and 56% in the winter wet season… 
Habitat selection and diurnal refugia of gray foxes in southwestern Georgia, USA
TLDR
The results suggest that on the study area, gray foxes are an edge species that prefer forests with a hardwood component in areas near human use and roads.
Mesocarnivore activity patterns in the semiarid Caatinga: limited by the harsh environment or affected by interspecific interactions?
TLDR
Nighttime-only activity comparisons showed that activity of oncillas differed from that of both larger mesocarnivores and jaguar activity, suggesting temporal segregation, and future studies in arid regions should consider climatic factors when estimating activity patterns.
Trophic niche overlap between coyotes and gray foxes in a temperate forest in Durango, Mexico
TLDR
Differences in trophic diversity caused by differential prey use can mitigate competitive interactions, allowing these different sized canid species to coexist in the study area.
USO DE HÁBITAT POR ZORRO GRIS (Urocyon cinereoargenteus, CARNIVORA: CANIDAE) EN UN ECOSISTEMA TROPICAL ANTROPIZADO
Background. Gray fox, Urocyon cinereoargenteus is tolerant to habitat disturbance, but the biotic and abiotic factors that determine the selection of space in the subperennial medium forest (SMF)
Coexistence of three mephitids in Tehuacán-Cuicatlán Biosphere Reserve, México
Three species of mephitids coexist in the Tehuacán-Cuicatlán biosphere reserve (TCBR) and belong to a guild of mammalian carnivores that feed mainly on invertebrates.  To infer the interspecific
Limitations of current knowledge about the ecology of Grey Foxes hamper conservation efforts
Species-specific conservation is important for maintaining the integrity of ecological communities but is dependent on sufficiently understanding multiple aspects of a species’ ecology.
Mammalian carnivore use of a high-severity burn in conifer forests in the San Bernardino mountains of southern California, USA
TLDR
C carnivore occurrence in a high severity burn for four years in mixed conifer forests in the San Bernardino Mountains of southern California, USA was investigated using camera trapping and negative binomial regression analysis.
Raining feral cats and dogs? Implications for the conservation of medium-sized wild mammals in an urban protected area
Mammals are one of the most negatively affected groups by urbanization, nevertheless, urban reserves can help their conservation. The study of wildlife within the reserves is important for the

Survival and cause‐specific mortality of gray foxes (Urocyon cinereoargenteus) in southern California
From May 1997 to July 1999, 24 gray foxes Urocyon cinereoargenteus were radio-marked and their fates monitored in a natural area of southern California to identify rates of survival and
Temporal habitat partitioning and spatial use of coyotes and red foxes in East-Central Illinois
TLDR
It is demonstrated that coyotes and sympatric red foxes partition habitat seasonally in response to a highly disturbed agricultural landscape.
Effects of Urbanization and Habitat Fragmentation on Bobcats and Coyotes in Southern California
Abstract: Urbanization and habitat fragmentation are major threats to wildlife populations, especially mammalian carnivores. We studied the ecology and behavior of bobcats (   Lynx rufus ) and
Resource partitioning between coyotes and swift foxes: space, time, and diet
TLDR
A high degree of interspecies spatial overlap was apparent, with fox home ranges being overlapped by coyote home ranges by as much as 100% and coyote sign (tracks and scats) being evident in all swift Fox home ranges.
Food Item Use by Three Sympatric Canids in Southern Illinois
TLDR
Despite competition for food resources, gray foxes appear able to coexist with coyotes possibly through habitat segregation and avoidance of antagonistic encounters by climbing trees.
Competition and intraguild predation among three sympatric carnivores
TLDR
It is proposed that coyotes limit the number and distribution of gray foxes in Santa Monica Mountains, and that those two carnivores exemplified a case in which the relationship between their body size and local abundance is governed by competitive dominance of the largest species rather than by energetic equivalences.
Causes and rates of mortality of swift foxes in Western Kansas
TLDR
Predation by coyotes was the major cause of mortality for adult and juvenile swift foxes in both study areas, and vehicle collision was an important mortality factor for juveniles in the cropland study area.
Patterns of den use by San Joaquin kit foxes
TLDR
Conservation of all kit fox dens is recommended because of the dynamic patterns of den use by kit foxes and potential importance of dens as escape cover.

A comparison of gray fox ecology between residential and undeveloped rural landscapes
TLDR
The ecology of gray foxes is compared between a rural residential area and an undeveloped area of similar natural habitat, which contained higher frequencies of mammal remains and lower frequencies of plant remains.
