Animal movement is fundamental for ecosystem functioning and species survival, yet the effects of anthropogenic footprint on animal movements have not been estimated across species. Using a unique GPS-tracking database 803 individuals 57 species, we found that mammals in areas with comparatively high human were average one-half to one-third extent their low footprint. We attribute this reduction behavioral changes individual animals exclusion long-range from higher impact. Global loss...
Abstract Changes in agricultural practices and forest fragmentation can have a dramatic effect on landscape connectivity the dispersal of animals, potentially reducing gene flow within populations. In this study, we assessed influence woodland traditionally forest‐dwelling species — European roe deer fragmented landscape. From sample 648 spatially referenced study area 55 × 40 km, interindividual genetic distances were calculated from genotypes at 12 polymorphic microsatellite loci. We two...
COVID-19 lockdowns in early 2020 reduced human mobility, providing an opportunity to disentangle its effects on animals from those of landscape modifications. Using GPS data, we compared movements and road avoidance 2300 terrestrial mammals (43 species) during the same period 2019. Individual responses were variable with no change average or behavior, likely due lockdown conditions. However, under strict 10-day 95th percentile displacements increased by 73%, suggesting permeability. Animals'...
Summary High‐density populations of large herbivores are now widespread. Wildlife managers commonly attempt to control through hunting meet specific management objectives, considering population density as the minimal key source information. Here, we review problems censusing and describe an alternative approach, employing indicators ecological change. Estimating with high precision accuracy is difficult, especially over areas, requires considerable investment time, people money. Management...
Ungulate populations exhibiting partial migration present a unique opportunity to explore the causes of general phenomenon migration. The European roe deer Capreolus capreolus is particularly suited for such studies due wide distribution range and high level ecological plasticity. In this study we undertook comparative analysis GPS location data from representative set ecosystems available within EURODEER collaborative project. We aimed at evaluating factors affecting tactic (i.e....
We tested the influence of population density and drought intensity (measured as Gaussen Index in spring summer year birth) on winter body mass, hind foot length, condition roe deer fawns. Body mass decreased with increasing increased summer, a similar way for both males females. Hind length showed same response. On other hand, females only after dry summers, hence when environmental conditions were very harsh. was affected neither by nor intensity. Our results indicate that size are much...
Summary Because many large mammal species have wide geographical ranges, spatially distant populations may be confronted with different sets of environmental conditions. Investigating how home range ( HR ) size varies across gradients should yield a better understanding the factors affecting ecology. We evaluated herbivore, roe deer C apreolus capreolus ), in relation to seasonality, latitude (climate), weather, plant productivity and landscape features its W estern E urope. As are income...
Abstract Deer (Cervidae) are key components of many ecosystems and estimating deer abundance or density is important to understanding these roles. Many field methods have been used estimate density, but the factors determining where, when, why a method was used, its usefulness, not investigated. We systematically reviewed journal articles published during 2004–2018 evaluate spatio‐temporal trends in study objectives, methodologies, estimates, determine how they varied with biophysical...
The psychrotrophic bacterium Arthrobacter globiformis SI55 was grown at 4 and 25 degrees C, the cell protein contents were analyzed by two-dimensional electrophoresis. Cells subjected to cold shocks of increasing magnitude also analyzed. Correspondence analysis appearance distinguished four groups physiological significance. Group I contained shock proteins (Csps) overexpressed only after a large temperature downshift. II Csps with optimal expression mild shocks. III all These last in cells...
Locating and monitoring animals using tracking devices is a method commonly used for many taxa to study characteristics such as home‐range size, habitat selection, movement patterns other aspects of ranging behaviour. Fitting requires the capture handling organism researchers must then assume that monitored animal behaves in ‘normal’ way. We investigated whether roe deer Capreolus capreolus induced behavioural alterations. In particular, we expected would exhibit ‘seeking refuge waiting...
Summary Natal dispersal is defined as the movement between natal range and site of first breeding one most important processes in population dynamics. The choice an individual makes philopatry may be condition dependent, influenced by either phenotypic attributes and/or environmental factors. Interindividual variability tactics has profound consequences for dynamics, particularly with respect to metapopulation maintenance. A better understanding mechanisms underlying this thus primary...
The way an individual reacts to the risk of predation or disturbance may have important consequences for its immediate and future survival. Risk is likely perceived differently by individuals in relation among-individual differences correlated behavioral traits, that is, syndromes personalities. Given animals can avoid predation/disturbance through modification their habitat use, we might expect differing types adopt contrasting tactics use when faced with risky stressful situations. We...
Most forests in Europe are patchily distributed within the agricultural landscape. Therefore, forest biogeochemistry cannot be understood without considering connectivity of nutrient cycles between patches and fertilized cropland. In this paper, we quantified role roe deer, most widespread wild ungulate Europe, as a vector nitrogen phosphorus from fields to patches, typical landscape southwestern Europe. We derived model transfer data set on deer density, landscape‐use by individual content...
Non‐consumptive effects of predators result from the cost responses to perceived risk. Prey modulate risk exposure through flexible habitat selection at multiple scales which, in interaction with landscape constraints, determines their use risky habitats. Identifying relative contributions constraints and is a critical first step towards mechanistic understanding non‐consumptive effects. Here, we provide an integrative multi‐scale study roe deer spatial variable hunting pressure along...
Satellite telemetry is an increasingly utilized technology in wildlife research, and current devices can track individual animal movements at unprecedented spatial temporal resolutions. However, as we enter the golden age of satellite telemetry, need in-depth understanding main technological, species-specific environmental factors that determine success failure tracking across species habitats. Here, assess relative influence such on ability units to provide expected amount quality data by...
Humans, as super predators, can have strong effects on wildlife behaviour, including profound modifications of diel activity patterns. Subsequent to the return large carnivores human-modified ecosystems, many prey species adjusted their spatial behaviour contrasting landscapes fear generated by both natural predators and anthropogenic pressures. The predation risk temporal shifts in prey, however, remain largely unexplored human-dominated landscapes. We investigated influence density lynx...
Body size of large herbivores is a crucial life history variable influencing individual fitness‐related traits. While the importance this parameter in determining temporal trends population dynamics well established, much less information available on spatial variation body at local infra‐population scale. The relatively recent increase landscape fragmentation over last century has lead to substantial heterogeneity habitat quality across modern agricultural landscape. In paper, we analyse...
Abstract: To determine the spatial resolution of Global Positioning System (GPS) receiver data, rigorous testing is essential. We tested performance Lotek 3300 GPS collar for medium‐sized mammals (Lotek Engineering, Inc., Newmarket, ON, Canada). mimic real wildlife monitoring situations, we performed both static (stationary receiver) and mobile tests, placing on a dog. compared fix locations with actual trajectory described by portable Trimble high‐precision GPS. determined in relation to...
