The impacts of biological invasions
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Brook trout passage performance through culverts [PDF]
Culverts can restrict access to habitat for stream-dwelling fishes. We used passive integrated transponder telemetry to quantify passage performance of >1000 wild brook trout (Salvelinus fontinalis) attempting to pass 13 culverts in Quebec under a range of hydraulic and environmental conditions.

Effect of polyploidization on survival of sea, brook, and rainbow trout hybrids during incubation and early feeding period [PDF]
Effect of polyploidization on survival of brook trout (Salvelinus fontinalis), sea trout (Salmo trutta morpha trutta) and rainbow trout (Salmo gairdneri) hybrids, including reciprocal crosses, during incubation and larval stages period was tested.

Plasticity of diel activity rhythms may be a key element for adaptations of wildlife populations to changing environmental conditions. In the last decades, grizzly bears Ursus arctos in the Greater Yellowstone Ecosystem (GYE) have experienced notable environmental fluctuations, including changes in availability of food sources and severe droughts ...
