Assessing the detectability of the Irish stoat Mustela erminea hibernica using two camera trap-based survey methods
Mammal Research - Tập 67 Số 1 - Trang 1-8 - 2022
Monitoring small mustelids like weasels Mustela nivalis and stoats M. erminea is challenging as they are rarely seen, leave scant field signs and display avoidance behaviour towards traps and monitoring devices. The Irish stoat M. erminea hibernica is a subspecies endemic to Ireland and the Isle of Man, and despite being widespread in Ireland, no information exists on its population status due to ......
Flexibility in the food selection by the European hare (Lepus europaeus) along the altitudinal gradient of the Southern Andean Precordillera (Argentina)
Mammal Research - Tập 62 - Trang 75-87 - 2016
Predictions derived from the optimal foraging theory are interesting to test on wild herbivores living in mountain environments, considering the expected vegetation changes across altitudinal gradients. A lower food richness and a more generalist diet are expected as altitude increases, with higher diet diversity and a shift to browsing as food availability decreases seasonally. With broad diets a......
Nutritional niche separation between native roe deer and the nonnative fallow deer—a test of interspecific competitionAbstract On an evolutionary time scale, competition for food drives species formation by genetic adaptations to the environment and subsequent niche separation. On a short-term scale, animals use different strategies to meet their nutritional requirements, which ultimately influence their fitness. Understanding these adaptations in herbivores is especially important... ...

Deforestation leads to prey shrinkage for an apex predator in a biodiversity hotspot
Mammal Research - - 2021
Deforestation is a key driver of biodiversity reduction worldwide and impacts ecosystem functioning, ecological processes, and species behavior. Here, we investigated the effects of deforestation on the diet of puma (Puma concolor) in the Brazilian Atlantic Forest. We characterized puma diets in the largest continuous Atlantic Forest remnant and compiled literature data on their diet across the bi......
New data on the distribution and intraspecific variation of the Millard’s giant rat Dacnomys millardi (Mammalia, Rodentia) from Vietnam
Mammal Research - Tập 62 - Trang 307-311 - 2017
The paper presents an analysis of a genetic and morphological variation of Dacnomys millardi from seven Vietnamese localities, including a new finding from southern Vietnam which lies some 1000 km to the south of the currently known limit of the species range. Samples from northern and southern Vietnam do not differ significantly in their cranial and oversize characteristics. Surprisingly, they ar......
The Mostela: an adjusted camera trapping device as a promising non-invasive tool to study and monitor small mustelids
Mammal Research - Tập 65 - Trang 843-853 - 2020
In spite of their potential important role in shaping small mammal population dynamics, weasel (Mustela nivalis) and stoat (Mustela erminea) are understudied due to the difficulty of detecting these species. Furthermore, their conservation status in many countries is unknown due to lack of monitoring techniques. There is thus an important need for a method to detect these small mustelids. In this ......
Pine marten vs. stone marten in agricultural lowlands: a landscape-scale, genetic survey
Mammal Research - Tập 61 Số 4 - Trang 327-335 - 2016
Does condition of adult male cervids reflect condition of adult females? A test with mule deer
Mammal Research - Tập 66 - Trang 595-602 - 2021
Body condition integrates the effects of habitat on individuals and consequently population performance of cervids. However, most condition data is likely to come from harvested males, which may not reflect absolute condition of, or habitat quality for, adult females because of basic ecological differences. To test whether condition of males reflected condition of females, we compared three indice......
Patterns of species co-occurrence in a diverse Eastern Himalayan montane carnivore community
Mammal Research - Tập 67 - Trang 139-149 - 2021
We investigated patterns of species richness and co-occurrence in a montane carnivore community within a forested landscape in Bhutan that ranged in altitude from 2000 to 3760 m above sea level, and covered an area of approximately 140 km2. Species were detected by unbaited camera traps set along animal trails and baited camera traps set away from trails. During the 6-month study, we gathered 1,32......
When prey provide more than food: mammalian predators appropriating the refugia of their prey
Mammal Research - Tập 60 - Trang 285-292 - 2015
Some mammalian predators acquire both food and shelter from their prey, by eating them and using the refugia the prey construct. I searched the literature for examples of predators that exhibit this behavior and summarize their taxonomic affiliations, relative sizes, and distributions. I hypothesized that size ratios of species involved in this dynamic would be near 1.0, and that most of these int......
