Soil-surface CO2 flux and growth in a boreal Norway spruce stand [PDF]

, 2001
Global warming is predicted to affect the carbon balance of forests. A change in the carbon balance would give a positive or negative feedback to the greenhouse effect, which would affect global warming.

Spring migration strategies differ among three waterfowl species that winter in southern New England, USA

Journal of Avian Biology, Volume 2026, Issue 3, May 2026.
Migratory birds face considerable temporal and energetic constraints during spring migration. To balance these demands and maximize breeding success, migratory birds may optimize spring migration by adopting a strategy that primarily favors either minimizing time or energy spent on migration.

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 ...

Hidden Markov Quantile Models With Trends for Analysing Air Temperature Data

International Journal of Climatology, Volume 46, Issue 6, May 2026.
There is the question of whether climate change, expressed by time‐trends in temperature, is of a heterogeneous nature or not. Here, the time‐trend heterogeneity argument has been investigated using Hidden Markov (HM) quantile time‐trends models in temperature time series.

Phenology, growth, and fecundity of eight subarctic tundra species in response to snowmelt manipulations [PDF]

, 2018
The snow cover extent is an important factor for the structure and composition of arctic and alpine tundra communities. Over the last few decades, snowmelt in many arctic and alpine regions has advanced, causing the growing season to start earlier and ...

Phenological responses to climate change: advancing mating and calving in wild and semi‐captive Caspian red deer

Wildlife Biology, Volume 2026, Issue 3, May 2026.
Species respond to climate change through phenological and spatial shifts. Herbivorous mammals, in particular, are vulnerable due to their direct dependence on seasonal vegetation and the potential misalignment between their reproductive cycles and shifting food availability.

A method for robust estimation of snow seasonality metrics from Landsat and Sentinel-2 time series data over Atlas Mountains scale using Google Earth Engine

Geocarto International
Seasonal snow cover provides the majority of freshwater supplies for human society and natural ecosystems especially in semi-arid regions. For water resource managers, precise data regarding the spatiotemporal variability of snow cover and snow phenology

Reduced snow cover at the alpine treeline: resistance and recovery of saplings. [PDF]

New Phytol
Summary At high elevations, tree saplings and shrubs are usually protected by mid‐winter snow cover, although climate change is expected to extend the snow‐free (SF) period. Exposure to winter drought, freeze–thaw events and freezing temperatures will therefore increase, inducing damages to the hydraulic system and to living cells, resulting in reduced

Indicators of Climate Change in the Northeast 2005 [PDF]

, 2005
Climate changes. It always has and always will. What is unique in modern times is that human activities are now a significant factor causing climate to change.

Annual survival in a dynamic species: pronghorn survival patterns across their northern range

Wildlife Biology, Volume 2026, Issue 3, May 2026.
Quantifying variation in demographic patterns, such as survival and recruitment, is critical for understanding population dynamics and informing evidence‐based and adaptive wildlife management. In this study, we leverage an extensive dataset from over 1000 GPS collared pronghorn Antilocapra americana to provide the first large‐scale evaluation of ...
