Home range size is a fundamental concept for understanding animal dispersion and ecological needs, it one of the most commonly reported attributes free-ranging mammals. Previous studies indicate that red foxes Vulpes vulpes display great variability in home size. Yet, there has been little consensus regarding reasons why sizes vary so extensively. In this study, we examine possible causes variation fox using data from 52 GPS collared four study areas representing gradient landscape...
Dispersal is a fundamental process that facilitates population and range expansion by providing mechanism for colonization metapopulation linkages. Yet quantifying the dispersal process, particularly long-distance events, has been inherently difficult due to technological observational limitations. Additionally, distance calculated as straight-line between initiation settlement fails account actual movement path of animal during dispersal. Here, we highlight six representing some longest...
Abstract Apex carnivores that rely primarily on predation play a central but complex role within scavenging ecology by potentially suppressing intra-guild competitors, also facilitating them providing reliable supply of carrion. We investigated the competitive relationship between sympatric wolves ( Canis lupus ) and wolverines Gulo gulo in Norway across three seasons. deployed remote cameras at fresh wolf kills n = 29) built Bayesian generalized linear mixed models (GLMMs) to explore use...
Many animals must adapt their movements to different conditions encountered during life phases, such as when exploring extraterritorial areas for dispersal, foraging or breeding. To better understand how move in movement we asked whether patterns differ between one way directed movements, the transient phase of dispersal two exploratory-like excursions stationary movements. We GPS collared red foxes a rural area southern Germany 2020 and 2023. Using random forest model, analyzed parameters,...
Migratory prey is a widespread phenomenon that has implications for predator–prey interactions. By creating large temporal variation in resource availability between seasons it becomes challenging carnivores to secure regular year‐round supply of food. Some predators may respond by following their migratory prey, however, most are sedentary and experience strong seasonal availability. Increased predation on alternative dampen such fluctuations, but reduced reproduction rates predicted...
Abstract The genetic structure of a population can provide important insights into animal movements at varying geographical scales. Individual and social behaviors, such as philopatry dispersal, affect patterns relatedness, age sex structure, shaping the local populations. However, these fine scale may not be detected within broader structure. Using SNP genotyping for pairwise relatedness estimates, we investigated spatial structuring 141 red foxes south-central Sweden two First, looked...
Rapid declines in red fox Vulpes vulpes populations have followed outbreaks of epizootic mange caused by the mite Sarcoptes scabiei . In Sweden, first outbreak sarcoptic started 1977/1978 and affected whole country 1984. Here we used data on number harvested foxes (51 480) from Gävleborg county (18 199 km 2 ) Sweden between 1970 1994. We prevalence a sample (2694) 1974 to 1982. A rapid decline occurred two three years after became evident. same period, mark–recovery were estimate changes...
The complex, interconnected, and non-contiguous nature of canopy environments present unique cognitive, locomotor, sensory challenges to their animal inhabitants. Animal movement through forest canopies is constrained; unlike most aquatic or aerial habitats, the three-dimensional space a not fully realized available animals within it. Determining how constraints arboreal habitats shape ecology evolution canopy-dwelling key understanding ecosystems. With emerging technologies, there now...
Abstract Global positioning system (GPS) technology is increasingly used to study animal behavior. However, some animals exhibit behaviors that may result in the failure acquire a GPS position, such as for species with underground denning This creates challenge researchers identify timing of important life-history events birth. Here, we tested if information gaps arising from unsuccessful positions, connection intrinsic and extrinsic factors, can parturition an species, red fox. Using data...
A home range represents the outcome of interplay between an environment, animal's understanding that and its subsequent movement decisions. Yet, recent studies suggest recursive strategies have been overlooked in shaping animal patterns. Using fourteen GPS collared red foxes, we investigated within movements for behaviour, suggesting a cognitive map, explored how these shape space-use We found foxes showed significant clustering recorded positions, indicative site use. An average 43%...
