Integration of national demographic-disturbance relationships and local data can improve caribou population viability projections and inform monitoring decisions Open
Across fifty-eight boreal caribou study areas in Canada, survival and recruitment decrease with the percentage of the study area that is disturbed. There is variation in demographic rates among study areas, particularly where anthropogenic…

Inter-colony variation in predation, mercury burden and adult survival in a declining seabird Open
Migratory species with disjunct and localized breeding distributions, including many colonial marine birds, pose challenges for management and conservation as their dynamics are shaped by both broad oceanographic changes and specific facto…

Movement ecology of endangered caribou during a <span>COVID</span>‐19 mediated pause in winter recreation Open
The long‐term conservation of species at risk relies on numerous, and often concurrent, management actions to support their recovery. Generally, these actions are habitat‐based while others are focused on a species' position within its eco…

River- and Sex-Specific Annual Survival Rates of Mature Anadromous Alewife (Alosa pseudoharengus) Open
During multiple annual spawning runs from 2013 to 2021, over 9,000 mature anadromous alewife (Alosa pseudoharengus A. Wilson, 1811) were monitored with passive integrated transponders (PITs) in four rivers of the Chignecto Isthmus, Bay of …

Apparent Survival Among Adult Leach's Storm Petrels <i>Hydrobates leucorhous</i> on a Colony Managed for Predators in Nova Scotia, Canada Open
Population declines of Leach’s Storm Petrels Hydrobates leucorhous in the western Atlantic have both led to the species’ recent assessment as Threatened in Canada and contributed to a Vulnerable designation by the IUCN. Limited information…

Adult survival and annual movement patterns of common snipe in Iceland Open
The common snipe (Gallinago gallinago) is a wader that breeds in subarctic regions from Iceland to Russia, and for which global populations are in decline. We studied snipe breeding in western Iceland between 1998 and 2020, locating nests …

Subpopulation contributions to a breeding metapopulation of migratory arctic herbivores: survival, fecundity and asymmetric dispersal Open
Estimates of demographic parameters for lesser snow geese Anser caerulescens caerulescens have become critical to understand ecosystem change in northern Canada. Exponential increase in abundance has produced hyperdensities of these herbiv…

Habitat loss accelerates for the endangered woodland caribou in western Canada Open
Habitat loss is often the ultimate cause of species endangerment and is also a leading factor inhibiting species recovery. For this reason, species‐at‐risk legislation, policies and plans typically focus on habitat conservation and restora…

Host traits and lifetime fitness costs of being parasitized in red-breasted mergansers Open
The addition of eggs to a nest by a conspecific is known for approximately 250 bird species. Understanding the evolution of conspecific brood parasitism (CBP) requires assessment of fitness consequences to the egg recipient (host). We addr…

How well does forestry in Ontario’s boreal forest emulate natural disturbances from the perspective of birds? Open
Emulating natural disturbance has become a paradigm for biodiversity retention in forest management. This study evaluates the extent to which harvest management practices have created stands that emulate natural fire disturbance from the p…

Do hyperabundant Arctic-nesting geese pose a problem for sympatric species? Open
Arctic-breeding geese are at record high population levels and are causing significant changes to some of their breeding and staging habitats. These changes could influence sympatric wildlife, but the nature and strength of these effects a…
