A random-forest-derived 35-year snow phenology record reveals climate trends in the Yukon River Basin [PDF]

The Cryosphere
This study presents a 35-year snow phenology record for the Yukon River Basin (YRB), developed using a random forest (RF) model at a 3.125 km resolution, capturing detailed trends in snowmelt onset and snow-off.

Bergmann's rule: Why does body size increase with latitude?

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Bergmann's rule describes the tendency for endothermic body size to increase with latitude, a pattern often attributed to climatic factors. However, the underlying developmental and evolutionary mechanisms remain debated.

A comparative study of satellite and ground-based phenology [PDF]

, 2018
Long time series of ground-based plant phenology, as well as more than two decades of satellite-derived phenological metrics, are currently available to assess the impacts of climate variability and trends on terrestrial vegetation.

Land surface phenology in the highland pastures of montane Central Asia: Interactions with snow cover seasonality and terrain characteristics

Remote Sensing of Environment, 2020
Abstract Many studies have shown that high elevation environments are among very sensitive to climatic changes and where impacts are exacerbated. Across Central Asia, which is especially vulnerable to climate change due to aridity, the ability of global climate projections to capture the complex dynamics of mountainous environments is particularly ...

Spatial overlap and temporal synchrony between guilds of insect hosts and parasitoids

Journal of Animal Ecology, EarlyView.
This study identified a spatial overlap between insect host guild richness and parasitoid richness. Species richness in parasitoid guilds always increased later in the season than richness of their host guilds. These findings suggest that shifts in climate and land‐use may alter the synchrony of insect trophic layers.

Predicting the effects of climate change on water yield and forest production in the northeastern United States [PDF]

, 1995
Rapid and simultaneous changes in temperature, precipitation and the atmospheric concentration of CO2 are predicted to occur over the next century. Simple, well-validated models of ecosystem function are required to predict the effects of these changes ...

Combined effects of warming, snowmelt timing, and soil disturbance on vegetative development in a grassland community [PDF]

, 2014
Climate warming and advanced snowmelt can simultaneously affect plant communities. However, the process of seasonal vegetative development under warming and early snowmelt conditions remains unclear, especially given that disturbance can amplify or ...
