Environmental drivers of metapopulation dynamics throughout the full annual cycle in a declining Arctic‐nesting migratory herbivore

Journal of Animal Ecology, EarlyView.
We provide a framework for extending commonly used integrated population models to a metapopulation framework for testing novel ecological hypotheses about how changing environmental conditions within and among subpopulations drive changes in animal abundance.

Changing Snow Regime Classifications Across the Contiguous United States

Water Resources Research
Climate change is impacting snow phenology in the Contiguous US (CONUS) and altering locations of elevated risk for floods driven by snowmelt. Our study uses a new spatial snow regime classification system to track climate driven changes in snow ...

Greater temperature sensitivity of plant phenology at colder sites: implications for convergence across northern latitudes [PDF]

, 2017
Warmer temperatures are accelerating the phenology of organisms around the world. Temperature sensitivity of phenology might be greater in colder, higher latitude sites than in warmer regions, in part because small changes in temperature constitute ...

Spatiotemporal Variability of Seasonal Snow Cover over 25 Years in the Romanian Carpathians: Insights from a MODIS CGF-Based Approach

Remote Sensing
Understanding long-term snow cover dynamics is essential in mountain regions with limited meteorological or in situ observations. This study examines seasonal snow cover evolution across the Romanian Carpathians (2000–2025) using daily MODIS/Terra ...

Cold hardiness mechanisms and modeling: existing approaches and future avenues. [PDF]

New Phytol
Summary Cold hardiness models are useful tools to predict cold damage in plants, such as those produced by unseasonal temperature cycles or by increased cold exposure. Although development of these models started about five decades ago, their applications remain limited.
