Wildlife management systems face growing challenges to cope with increasingly complex interactions between wildlife populations, the environment and human activities. In this position statement, we address the most important issues characterising current ungulate conservation and management in Europe. We present some key points arising from ecological research that may be critical for a reassessment of ungulate management in the future.

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 of 2300 terrestrial mammals (43 species) during the lockdowns to the same period in 2019. Individual responses were variable with no change in average movements or road avoidance behavior, likely due to variable lockdown conditions. However, under strict lockdowns 10-day 95th percentile displacements increased by 73%, suggesting increased landscape permeability. Animals’ 1-hour 95th percentile displacements declined by 12% and animals were 36% closer to roads in areas of high human footprint, indicating reduced avoidance during lockdowns. Overall, lockdowns rapidly altered some spatial behaviors, highlighting variable but substantial impacts of human mobility on wildlife worldwide.

Collisions with vehicles are a major cause of wildlife mortality. During the COVID‐19 pandemic, many countries enforced lockdowns that reduced vehicular traffic and consequently wildlife‐vehicle collisions. However, no study has yet explored how traffic‐related mortality declined across multiple species of wildlife, leaving doubts about the species‐specific impact of COVID‐19 on wildlife ecology and management. We modelled how two lockdowns (in spring and autumn 2020) influenced wildlife‐vehicle collisions throughout Slovenia, in central Europe, by comparing weekly roadkill in 2020 with 2010–2019 time series for European roe deer (n = 53,259), red fox (n = 9,889), Eurasian badger (n = 5,170), brown hare (n = 5,050), stone marten (n = 4,267), wild boar (n = 1,188) and red deer (n = 1,088). During the spring lockdown (16 March–30 April 2020), we observed far fewer collisions than expected for roe deer and badgers. During the autumn lockdown (20 October–31 December 2020), we observed significantly fewer collisions for roe deer and wild boar, but we noted an excess of collisions with badgers. Traffic reduction had a major influence on roe deer, whose roadkill decreased between 156 and 321 individuals. Heterogeneous changes in road mortality across the seven studied species indicate that reductions in human mobility can trigger complex species‐specific dynamics in wildlife assemblages, which may generate compensatory effects beyond lockdowns. For some species, such as roe deer, local reductions in the number of roadkill attained a significant fraction of the overall mortality. This could affect local population dynamics in cases where lockdowns are repeated over a number of years. Policy implications. Management aimed at reducing vehicular traffic, and therefore human disturbance and roadkill, can be evaluated using time‐series analysis of data on multiple species. During times of restricted human movement, local‐scale reductions should be estimated and accounted for in adaptive management, such as for planning culling quotas, to minimize their ecological and socio‐economic impacts while optimizing the outcomes of science‐based population management.

The capital and income breeding concept links energy resources used during reproduction to the timing of their acquisition. During reproduction, capital breeders rely on resources gained previously and accumulated for reproductive investment. By contrast, income breeders use mainly resources collected during the period of reproductive activity. Most commonly, this concept is applied to females; relatively few studies have considered males. Moreover, there has been little attention to the link between the capital-income divide and other aspects of mating strategy. We studied adult males of three wild ungulates with different levels of polygyny. A large dataset (4,264 red deer, 53,619 roe deer, and 13,537 Alpine chamois, respectively) was obtained during 2007–2017 in the whole territory of Slovenia and in the Trento province, Italy. During the rut, body mass loss of males in highly polygynous species was more than twice that of weakly polygynous species: on average, red deer stags lost 19.5%; chamois bucks 16.0%; and roe deer bucks 7.5% of their body mass. This indicates potential for a hitherto unrecognized link between the degree of intrasexual competition and the degree of capital mating. The variability in body mass at the end of the rut was clearly reduced in both highly polygynous species (from 15.1 to 9.4% in red deer, and from 12.5 to 10.5% in chamois), but did not change in roe deer. Finally, roe deer bucks had recovered body mass to that of the pre-rut period by just 2 months after the rut, while red deer stags did not manage to compensate the loss of weight until the end of the year. We suggest that, at least in ungulates, there is a link between the degree of polygyny and that of capital breeding. Males of capital and income breeders underwent body mass changes resulting from different reproductive investment during the rut. Capital breeders lost considerably more weight, and invested a variable amount of energy among individuals or among years, possibly to cope with different environmental or body conditions. In so doing, they ended the rut with poorer but more even condition among individuals.

The chamois Rupicapra spp. is the most abundant mountain ungulate of Europe and the Near East, where it occurs as two species, the northern chamois R. rupicapra and the southern chamois R. pyrenaica . Here, we provide a state‐of‐the‐art overview of research trends and the most challenging issues in chamois research and conservation, focusing on taxonomy and systematics, genetics, life history, ecology and behavior, physiology and disease, management and conservation. Research on Rupicapra has a longstanding history and has contributed substantially to the biological and ecological knowledge of mountain ungulates. Although the number of publications on this genus has markedly increased over the past two decades, major differences persist with respect to knowledge of species and subspecies, with research mostly focusing on the Alpine chamois R. r. rupicapra and, to a lesser extent, the Pyrenean chamois R. p. pyrenaica . In addition, a scarcity of replicate studies of populations of different subspecies and/or geographic areas limits the advancement of chamois science. Since environmental heterogeneity impacts behavioral, physiological and life history traits, understanding the underlying processes would be of great value from both an evolutionary and conservation/management standpoint, especially in the light of ongoing climatic change. Substantial contributions to this challenge may derive from a quantitative assessment of reproductive success, investigation of fine‐scale foraging patterns, and a mechanistic understanding of disease outbreak and resilience. For improving conservation status, resolving taxonomic disputes, identifying subspecies hybridization, assessing the impact of hunting and establishing reliable methods of abundance estimation are of primary concern. Despite being one of the most well‐known mountain ungulates, substantial field efforts to collect paleontological, behavioral, ecological, morphological, physiological and genetic data on different populations and subspecies are still needed to ensure a successful future for chamois research and conservation.
