    Mechanistic movement models identify continuously updated autumn migration cues in Arctic caribou

    Migrations in temperate systems typically have two migratory phases, spring and autumn, and many migratory ungulates track the pulse of spring vegetation growth during a synchronized spring migration. In contr...

    Spatiotemporally variable snow properties drive habitat use of an Arctic mesopredator

    Climate change is rapidly altering the composition and availability of snow, with implications for snow-affected ecological processes, including reproduction, predation, habitat selection, and migration. How s...

    Reproductive success delays moult phenology in a polar mammal

    Animals can respond to dynamic environments through phenological plasticity of life history events; however, changes in one part of the annual cycle can diminish the success of subsequent life history events. ...

    Losing a battle but winning the war: moving past preference–performance to understand native herbivore–novel host plant interactions

    Introduced plants can positively affect population viability by augmenting the diet of native herbivores, but can negatively affect populations if they are subpar or toxic resources. In organisms with complex ...

    Behavioral consequences of exotic host plant adoption and the differing roles of male harassment on female movement in two checkerspot butterflies

    Herbivorous insects may evolve convergent behaviors when independent adoption of a shared novel host plant places populations in environmental conditions that diverge from the ancestral state. We investigated ...

    Cumulative human impacts on marine predators

    Stressors associated with human activities interact in complex ways to affect marine ecosystems, yet we lack spatially explicit assessments of cumulative impacts on ecologically and economically key components...

    Climate-driven changes in northeastern US butterfly communities

    Climate-induced range shifts have been detected in a number of European species for which long-term survey data are available. In North America, well-organized long-term data needed to document such shifts are...

    An organic carbon budget for the Mississippi River turbidity plume and plume contributions to air-sea CO2 fluxes and bottom water hypoxia

    We investigated seasonal variability in organic carbon (OC) budgets using a physical-biological model for the Mississippi River turbidity plume. Plume volume was calculated from mixed layer depth and area in e...
