(IF 1.381) Pub Date : 2020-07-16 Olmo Linares; Juan Carranza; Mario Soliño; Miguel Delibes-Mateos; Pablo Ferreras; Esther Descalzo; María Martínez-Jauregui
The Egyptian mongoose (Herpestes ichneumon L.) is a medium-size carnivore widely distributed in Africa and in a small part of southern Europe, the Iberian Peninsula, where mongoose populations have recently expanded. The mongoose is relatively easily detectable because of its diurnal habits and because it is the only species of Herpestidae occurring in the Iberian Peninsula. Therefore, its distribution

Surveillance and habitat diversity affect European brown hare ( Lepus europaeus ) density in protected breeding areas Eur. J. Wildl. Res. (IF 1.381) Pub Date : 2020-07-16 Luca Canova; Andrea Gazzola; Lorenzo Pollini; Alessandro Balestrieri
The European brown hare (Lepus europaeus) is an important game species throughout Europe. In Italy, for preventing the introduction of allochthonous strains, the management of brown hare populations has focused on the establishment of small protected areas (ZRCs), appositely managed for disposing of wild-born hares for restocking hunting territories. We investigated the effects of both land cover and

Rapid assessment of site occupancy by collared pika ( Ochotona collaris ) at the leading edge of their range Eur. J. Wildl. Res. (IF 1.381) Pub Date : 2020-07-15 Piia M. Kukka; Julie P. Thomas; Justine E. Benjamin; Thomas S. Jung
Global climate change is a threat to the persistence of many species, particularly those that may experience climate-induced habitat loss, have limited dispersal ability, and a narrow ecological breadth. The collared pika (Ochotona collaris) is a small, cold-adapted mammal that meets these criteria. For species that are particularly vulnerable to climate warming, such as collared pika, conservation

Automated detection of European wild mammal species in camera trap images with an existing and pre-trained computer vision model Eur. J. Wildl. Res. (IF 1.381) Pub Date : 2020-07-14 Christin Carl; Fiona Schönfeld; Ingolf Profft; Alisa Klamm; Dirk Landgraf
The use of camera traps is a nonintrusive monitoring method to obtain valuable information about the appearance and behavior of wild animals. However, each study generates thousands of pictures and extracting information remains mostly an expensive, time-consuming manual task. Nevertheless, image recognition and analyzing technologies combined with machine learning algorithms, particularly deep learning

Bat activity and evidence of bat migration at two high elevation passes in the Western Alps Eur. J. Wildl. Res. (IF 1.381) Pub Date : 2020-07-14 Enrico Caprio; Elena Patriarca; Paolo Debernardi
Information about bat migration routes across the Alps is generally scarce and there is no existing data available for the Italian part of the chain. Through acoustic surveys, we explored the possibility that even a region characterized by high Alpine mountains may be crossed by migrant bats. Data were recorded in August–September 2016 at two sites located near mountain passes in the Aosta Valley (NW

Modelling and mapping the current and future potential habitats of the Algero-Tunisian endemic newt Pleurodeles nebulosus under climate change Eur. J. Wildl. Res. (IF 1.381) Pub Date : 2020-07-12 Hammadi Achour; Mohsen Kalboussi
Amphibians, especially salamanders, are particularly vulnerable to climate change because of their narrow dispersal abilities and strong dependence on water. In this study, we assessed the potential impact of climate change on the distribution of the Algerian ribbed newt (Pleurodeles nebulosus), a salamander species endemic of Algeria and Tunisia. Using the software “Maxent”, we predicted current and

Density of wild felids in Sonora, Mexico: a comparison of spatially explicit capture-recapture methods Eur. J. Wildl. Res. (IF 1.381) Pub Date : 2020-07-07 Evan Greenspan; Stefano Anile; Clayton K. Nielsen
Estimates of population density are crucial for wild felid conservation and are commonly conducted using camera trapping. Spatially explicit capture-recapture (SCR) survey designs often use two cameras per station to photograph both flanks of a spotted felid to confirm identities. However, if the sampling grid is inadequate, and detector devices are unable to capture an animal’s complete movements

Ungulate-vehicle collision risk and traffic volume on roads Eur. J. Wildl. Res. (IF 1.381) Pub Date : 2020-07-06 Michal Bíl; Jan Kubeček; Richard Andrášik
We analyzed data from traffic counters installed on 143 Czech roads (motorways and primary roads) which precisely indicated current traffic volume during occurrences of ungulate-vehicle collisions (UVC). One thousand nine hundred ninety-five UVCs were identified over the period 2009–2015 on these 143 road segments. The overall range of annual average daily traffic (AADT) values, for the respective

Temporal patterns of ungulate-vehicle collisions in a sparsely populated country Eur. J. Wildl. Res. (IF 1.381) Pub Date : 2020-07-02 Gytautas Ignatavičius; Alius Ulevičius; Vaidotas Valskys; Giedrius Trakimas; Lina Galinskaitė; Peter E. Busher
Ungulates (mainly Cervidae and wild boar Sus scrofa) are considered among the most problematic wildlife suffering on roads and causing the largest material losses due to high densities of ungulate populations, spatial and temporal movement patterns, and body size of these animals. Roe deer–vehicle collision (RDVC) as the most usual cause of ungulate fatality on roads may be applied as an appropriate

Effect of landscape type, elevation, vegetation period, and taxonomic plant identification level on diet preferences of Alpine mountain hares ( Lepus timidus varronis ) Eur. J. Wildl. Res. (IF 1.381) Pub Date : 2020-06-30 Stéphanie C. Schai-Braun; Katharina Lapin; Karl-Georg Bernhardt; Paulo C. Alves; Klaus Hackländer
Diet is important for understanding the ecology and evolution of populations. When examining animals’ diets, the lowest taxonomic rank (i.e., species level) is generally used. However, it is questionable whether dietary description varies with respect to the plant taxonomy or with the extent of plant species diversity in landscapes. We studied the diet of the Alpine mountain hare (Lepus timidus varronis)

Evaluation of long-term 11-oxoaetiocholanolone stability in red deer faecal samples under different storage conditions Eur. J. Wildl. Res. (IF 1.381) Pub Date : 2020-06-23 Jesús M. Pérez; José Espinosa; Mathieu Boos; Concepción Azorit; Lucía Molina; Antonio J. López-Montoya
Faecal cortisol metabolite (FCM) analysis is a reliable non-invasive method used in field endocrinology studies to assess levels of stress in animals. It is known that weather and, above all, humidity, can affect FCM concentrations in faecal samples. In addition, the prolonged storage of samples and delay in their analysis may alter metabolite concentrations. Intrinsic factors such as the heterogeneous
