Abstract:
... There is a large demand for bear parts in the Czech Republic, and this drives legal and illegal trade in various bear species sourced from outside the country. From 2010 to 2018, the Czech Republic reported legal imports of 495 bear parts, mostly as trophies from Canada and Russia. Illegal trade in bear parts and derivatives for medicine as well as trophies persists as evidenced by the number of s ...

Abstract:
... Movement ecology is fundamental to understanding animal home ranges or utilization distribution (UD), and is an important aspect in conservation management strategies. Over the years, there have been several new developments and some contention on which methods are best in determining animal movement and UD. Using data from Global Positioning System (GPS)-tracked Sumatran elephants, minimum convex ...

Abstract:
... Roads are one of the most severe threats to wildlife globally because of their pervasive and linear nature. Despite considerable attention afforded to road-effects on animals generally, little information is available concerning the specific impacts of road widening, also known as twinning or highway expansion. To address this gap, we monitored the abundance and distribution of large mammals adjac ...

Abstract:
... Wildlife corridors are a policy tool to maintain or restore connectivity through human-modified landscapes. While corridors have been an important concept in wildlife conservation for decades, there is little evidence to guide their design. Specifically, width is one of the most contentious dimensions of corridors because it often limits industrial, residential, or recreational expansion. Building ...

Abstract:
... 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 va ...

As such, wildlife managers often rely on harvest records to identify broad-scale harvest patterns and trends. Yet, the reliability of harvest records is often unknown. Analyses of harvest records to determine quotas and assess sustainability need to account for e ...

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 heteroge ...

This in turn leads to weight loss in adults, lower milk production in mothers, and growth retardation in young. An ungulate’s first line of defense against blood-sucking flies is its insect-repelling behaviors ...
