Streams provide essential ecosystem services including nutrient cycling and uptake, organic matter processing and ecosystem production and respiration. Stream ecosystem functioning provides an integrated metric of biological structures and processes that can respond to anthropogenic land use...

As old-growth forest ecosystems become increasingly scarce in North America, the need to accurately and efficiently survey, monitor, and model old-growth specialists and keystone species, such as the Pileated Woodpecker (Dryocopus pileatus), becomes increasingly important. Little is known about...

Feather mites (Acariformes: Sarcoptiformes: Analgoidea and Pterolichoidea) are a group of small arachnids that inhabit the feathers of nearly every species of bird. Life as ectosymbionts has shaped the morphology and ecology of feather mites, whose entire life cycles (from egg to adult) are...

Genetic variation is a ubiquitous feature of natural populations and underpins much phenotypic variation. Genetic variance can be partitioned and examined at various hierarchical levels of organization to address fundamental questions in ecology and evolution. Patterns of genetic variance among...

Caribou (Rangifer tarandus) numbers continue to decline across their circumpolar range with boreal woodland caribou (R. t. caribou; hereafter caribou) listed as threatened under Canada’s Species at Risk Act. Given this conservation concern, evaluating the factors influencing reproductive success...

Habitat fragmentation occurs when continuous habitat gets broken up as a result of ecosystem change. While commonly studied in terrestrial ecosystems, Arctic sea ice ecosystems also experience fragmentation, but are rarely studied in this context. Most fragmentation analyses are conducted using...

The culture of ecology is shifting towards collaborative, integrative approaches that use ‘big data’ to solve big problems. Passive acoustic monitoring (PAM) has the potential to play a role in this new paradigm because it uses in-situ autonomous recording units (ARUs) to collect a permanent...
