Identifying key marine habitat sites for seabirds and sea ducks in the Canadian Arctic
ML Mallory, AJ Gaston, JF Provencher… - Environmental …, 2019 - cdnsciencepub.com
The Canadian Arctic hosts millions of marine birds annually, many of which aggregate in
large numbers at well-defined sites at predictable times of the year. Marine habitats in this …

Breeding latitude drives individual schedules in a trans-hemispheric migrant bird
Despite clear benefits of optimal arrival time on breeding grounds, migration schedules may
vary with an individual bird's innate quality, non-breeding habitat or breeding destination …

Advancement in long-distance bird migration through individual plasticity in departure
Globally, bird migration is occurring earlier in the year, consistent with climate-related
changes in breeding resources. Although often attributed to phenotypic plasticity, there is no …

Absolute consistency: individual versus population variation in annual-cycle schedules of a long-distance migrant bird
Flexibility in scheduling varies throughout an organism's annual cycle, reflecting relative
temporal constraints and fitness consequences among life-history stages. Time-selection …

Geographic variation in the intensity of warming and phenological mismatch between Arctic shorebirds and invertebrates
Responses to climate change can vary across functional groups and trophic levels, leading
to a temporal decoupling of trophic interactions or “phenological mismatches.” Despite a …

Effects of food abundance and early clutch predation on reproductive timing in a high Arctic shorebird exposed to advancements in arthropod abundance
Climate change may influence the phenology of organisms unequally across trophic levels
and thus lead to phenological mismatches between predators and prey. In cases where prey …

Predicting vulnerabilities of North American shorebirds to climate change
Despite an increase in conservation efforts for shorebirds, there are widespread declines of
many species of North American shorebirds. We wanted to know whether these declines …

Integrating snow science and wildlife ecology in Arctic-boreal North America
NT Boelman, GE Liston, E Gurarie… - Environmental …, 2019 - iopscience.iop.org
Snow covers Arctic and boreal regions (ABRs) for approximately 9 months of the year, thus
snowscapes dominate the form and function of tundra and boreal ecosystems. In recent …
