EFFECTS OF LAND COVER, WATER REDISTRIBUTION, AND TEMPERATURE ON ECOSYSTEM PROCESSES IN THE SOUTH PLATTE BASIN [PDF]

, 1998
Over one‐third of the land area in the South Platte Basin of Colorado, Nebraska, and Wyoming, has been converted to croplands. Irrigated cropland now comprises 8% of the basin, while dry croplands make up 31%.

New opportunities for grassland species in warming temperate winters

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Temperate winters are getting warmer, the length of the growing season is increasing and mid‐winter fluctuations of warm and freezing temperatures are more frequent. Although typically winter dormant, some herbaceous perennials can maintain or grow green leaves during ...

Can snow depth be used to predict the distribution of the high Arctic aphid Acyrthosiphon svalbardicum (Hemiptera: Aphididae) on Spitsbergen?

BMC Ecology, 2011
Background The Svalbard endemic aphid Acyrthosiphon svalbardicum (Heikinheimo, 1968) is host specific to Dryas octopetala L. ssp octopetala (Rosaceae).

How much variation in land surface phenology can climate oscillation modes explain at the scale of mountain pastures in Kyrgyzstan?

International Journal of Applied Earth Observations and Geoinformation, 2020
Climate oscillation modes can shape weather across the globe due to atmospheric teleconnections. We built on the findings of a recent study to assess whether the impacts of teleconnections are detectable and significant in the early season dynamics of ...

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 ...

Internal physiological drivers of leaf development in trees: Understanding the relationship between non‐structural carbohydrates and leaf phenology

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...

From low to high elevations, flowers adapt traits and phenology to climate, but phenology‐trait relationships weak

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Flowering phenology is central to plant reproductive success and can relate to morphological traits such as size and quality of flowers, but phenology–trait associations of flowers remain unclear.

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 ...

The performance of growing degree day models to predict spring phenology of herbaceous species depends on the species' temporal niche

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The concept of growing degree days (GDDs) is commonly used to predict phenological events in plants, assuming that plants develop proportionally to the accumulated temperature. Two species‐specific parameters, TBase and t0 (minimum temperature above which and start date
