Distributions of LRS in varying environments.

Ecol Lett 2021 Apr 26. Epub 2021 Apr 26.

Laboratoire de Biométrie et Biologie Evolutive, Université de Lyon, Villeurbanne, France.

The lifetime reproductive success (LRS) of individuals is affected by random events such as death, realized growth or realized reproduction, and the outcomes of these events can differ even when individuals have identical probabilities. Another source of randomness arises when these probabilities also change over time in variable environments. For structured populations in stochastic environments, we extend our recent method to determine how birth environment and birth stage determine the random distribution of the LRS. Read More

Fluoride concentration in teeth of the roe deer (Capreolus capreolus) and red deer (Cervus elaphus) from areas of Poland industrially uncontaminated with fluoride compounds.

Pol J Vet Sci 2021 Mar;24(1):151-157

Pomeranian Medical University in Szczecin, Department of Dental Prosthetics, Powstańców Wlkp. 72, 71-111 Szczecin, Poland.

The last biomonitoring study in Poland on intoxication with fluoride compounds of deer was conducted almost two decades ago. Given the fact that fluoride level in air and water is not widely monitored in Poland, it is justified to undertake monitoring of F- levels in people and other long-lived mammals. This paper provides the assessment of the present level of fluoride accumulation in mineralized tissue of large herbivorous mammals. Read More

Experimental evidence of memory-based foraging decisions in a large wild mammal.

Proc Natl Acad Sci U S A 2021 Apr;118(15)

Department of Organismic and Evolutionary Biology, Harvard University, Cambridge MA 02138.

Many animals restrict their movements to a characteristic home range. This constrained pattern of space use is thought to result from the foraging benefits of memorizing the locations and quality of heterogeneously distributed resources. However, due to the confounding effects of sensory perception, the role of memory in home-range movement behavior lacks definitive evidence in the wild. Read More

Climate change and anthropogenic food manipulation interact in shifting the distribution of a large herbivore at its altitudinal range limit.

Sci Rep 2021 Apr 7;11(1):7600. Epub 2021 Apr 7.

Department of Organismic and Evolutionary Biology, Harvard University, Cambridge, MA, USA.

Ungulates in alpine ecosystems are constrained by winter harshness through resource limitation and direct mortality from weather extremes. However, little empirical evidence has definitively established how current climate change and other anthropogenic modifications of resource availability affect ungulate winter distribution, especially at their range limits. Here, we used a combination of historical (1997-2002) and contemporary (2012-2015) Eurasian roe deer (Capreolus capreolus) relocation datasets that span changes in snowpack characteristics and two levels of supplemental feeding to compare and forecast probability of space use at the species' altitudinal range limit.

An evaluation of machine learning classifiers for next-generation, continuous-ethogram smart trackers.

Mov Ecol 2021 Mar 30;9(1):15. Epub 2021 Mar 30.

Centre for Integrative Ecology, School of Life and Environmental Sciences, Deakin University, Geelong, Victoria, Australia.

Background: Our understanding of movement patterns and behaviours of wildlife has advanced greatly through the use of improved tracking technologies, including application of accelerometry (ACC) across a wide range of taxa. However, most ACC studies either use intermittent sampling that hinders continuity or continuous data logging relying on tracker retrieval for data downloading which is not applicable for long term study. To allow long-term, fine-scale behavioural research, we evaluated a range of machine learning methods for their suitability for continuous on-board classification of ACC data into behaviour categories prior to data transmission.

Temporal patterns of roe deer traffic accidents: Effects of season, daytime and lunar phase.

PLoS One 2021 30;16(3):e0249082. Epub 2021 Mar 30.

Institute of Wildlife Biology and Game Management, University of Natural Resources and Life Sciences, Vienna (BOKU), Austria.

Wildlife-related accidents, especially deer-vehicle accidents, pose a serious problem for road safety and animal protection in many countries. Knowledge of spatial and temporal patterns of deer-vehicle accidents is inevitable for accident analysis and mitigation efforts with temporal deer-vehicle accident data being much more difficult to obtain in sufficient data quality. We described the temporal patterns of roe deer (Capreolus capreolus) roadkills occurring in the period 2002-2006 in southeastern Austria. Read More

Early life investment in antlers and body growth reflects adult performance in roe deer population under supplementary feeding conditions.

Integr Zool 2021 Mar 16. Epub 2021 Mar 16.

Departamento de Sistemas y Recursos Naturales, Universidad Politécnica de Madrid, Madrid, Spain.

Recent research has challenged the idea that cervid antlers are such costly traits, supporting the assertion early-life antler investment is an honest signal of adult phenotypic quality. However, inferences were made based on antler measurements while growing (velvet) and thus, studies on fully-formed clean antlers are needed to avoid possible bias caused by the inter-individual variation in antler growth phenology. We studied a semi-captive population of European roe deer inhabiting a sub-Mediterranean area (Valsemana research station) and living under optimal conditions (ad libitum food supply and veterinary care).

Sex differences in condition dependence of natal dispersal in a large herbivore: dispersal propensity and distance are decoupled.

Proc Biol Sci 2021 Mar 10;288(1946):20202947. Epub 2021 Mar 10.

Istituto dei Sistemi Complessi, CNR, via Madonna del Piano 10, Sesto Fiorentino 50019, Italy.

Evolution should favour plasticity in dispersal decisions in response to spatial heterogeneity in social and environmental contexts. Sex differences in individual optimization of dispersal decisions are poorly documented in mammals, because species where both sexes commonly disperse are rare. To elucidate the sex-specific drivers governing dispersal, we investigated sex differences in condition dependence in the propensity and distance of natal dispersal in one such species, the roe deer, using fine-scale monitoring of 146 GPS-collared juveniles in an intensively monitored population in southwest France.

Current and historical nephric and hepatic mercury concentrations in terrestrial mammals in Poland and other European countries.

Sci Total Environ 2021 Jun 12;775:145808. Epub 2021 Feb 12.

Department of Environmental Management, West Pomeranian University of Technology, Szczecin, Poland.

The long-term anthropogenic release of mercury (Hg) into the environment has led to contamination of the biosphere, with all forms of Hg showing toxic effects and the ability to accumulate in organisms. Since the 1970s, efforts have been made in Western Europe to reduce Hg emissions and for the economic use of Hg, leading to a reduction in Hg exposure to humans and entire ecosystems. The purpose of this research was to present the total mercury (THg) burden in three mustelids (the piscivorous Eurasian otter and American mink, and the invertebrativorous European badger) inhabiting north-western Poland (mostly floodplains) and other European countries (literature data).

Wildlife as Sentinels of Antimicrobial Resistance in Germany?

Front Vet Sci 2020 27;7:627821. Epub 2021 Jan 27.

Department Biological Safety, German Federal Institute for Risk Assessment (BfR), Berlin, Germany.

The presence of bacteria carrying antimicrobial resistance (AMR) genes in wildlife is an indicator that resistant bacteria of human or livestock origin are widespread in the environment. In addition, it could represent an additional challenge for human health, since wild animals could act as efficient AMR reservoirs and epidemiological links between human, livestock and natural environments. The aim of this study was to investigate the occurrence and the antibiotic resistance patterns of several bacterial species in certain wild animals in Germany, including wild boars (), roe deer () and wild ducks (family Anatidae, subfamily Anatinae) and geese (family Anatidae, subfamily Anserinae).

Characterization of New Molecular Markers of Three Botflies Parasitizing Cervid Hosts.

J Med Entomol 2021 Feb 4. Epub 2021 Feb 4.

Departamento de Biología Experimental, Universidad de Jaén, Campus Las Lagunillas, s.n., Jaén, Spain.

Specific identification of oestrid larvae is usually problematic not only when using morphobiometric features, but also when applying molecular criteria, since very few molecular markers have been described for this group of flies. New molecular markers for oestrid are needed for more reliable species identification, diagnostic purposes, and epidemiological surveys; moreover, they can help in phylogenetic reconstruction. Here, we report the characterization of COI, 28S rDNA, ITS1, and ITS2 in Cephenemyia stimulator from roe deer and in Cephenemyia auribarbis and Pharyngomyia picta from red deer. Read More

Maternal effects shape offspring physiological condition but do not senesce in a wild mammal.

J Evol Biol 2021 Apr 3;34(4):661-670. Epub 2021 Mar 3.

Laboratoire de Biométrie et Biologie 8 Evolutive UMR5558, Université de Lyon, Université Lyon 1, CNRS, Villeurbanne, France.

In vertebrates, offspring survival often decreases with increasing maternal age. While many studies have reported a decline in fitness-related traits of offspring with increasing maternal age, the study of senescence in maternal effect through age-specific changes in offspring physiological condition is still at its infancy. We assessed the influence of maternal age and body mass on offspring physiological condition in two populations of roe deer (Capreolus capreolus) subjected to markedly different environmental conditions.
