The impact of seasonal variability of rainfall and drought on vegetation and livestock population in Central District, eastern Botswana

Grassland Research
Background This research aimed to elucidate the components of rainfall variation, their influence on the natural vegetation growing season and consequent impacts on the livestock population.

Spatial and temporal exposure to climatic extremes shape butterfly thermal physiology and vulnerability to recent climate change

Ecography, EarlyView.
Whether the limits of species' ranges and their seasonal activity reflect physiological tolerance of climatic extremes is a long‐standing question in ecology and has implications for species' responses to recent climate change. We explored these associations in butterflies, using thermal tolerance traits and traits describing geographic distribution ...

Impact of land management on herbaceous vegetation diversity and forage provision in the Great Green Wall in Burkina Faso

Grassland Research
Background In West African semi‐arid areas, grazing ecosystems are exposed to severe anthropogenic and climatic pressures. However, little is known about the contribution of local land management practices to increasing herbaceous forage in semi‐arid ...

Extinct Pleistocene carnivores were diurnal and highly active

Ecography, EarlyView.
There is much contention over the causes and correlates of megafaunal extinctions at the end of the Pleistocene. A major role for human impact such as hunting has been discussed widely. If correct, the overkill hypothesis explains not only why large mammals in general were highly prone to extinction but suggests that extinction may have been selective ...

Fructan biosynthesis gene expression upon cold acclimation in orchardgrass (Dactylis glomerata L.)

Grassland Research
Background Fructan content and flux in temperate forages can benefit the grasses through increased cold hardiness, increased drought tolerance, and improved forage quality.

Divergent projections of future African biome shifts with process‐based and species distribution models

Ecography, EarlyView.
Future climate change is expected to influence ecosystem dynamics and the biogeographic distribution of biomes. Such shifts would have profound impacts on biodiversity and the provision of ecosystem services that are essential for humans. A robust understanding of potential future biome changes is therefore required to inform conservation and ...

Selection of meadow fescue for persistence under frequent defoliation

Grassland Research
Background Meadow fescue (Schedonorus pratensis (Huds.) P. Beauv.) is a reemerging pasture grass for temperate regions of North America. One disadvantage of this species is its lack of tolerance to frequent defoliation at low residual sward heights. This

Long‐term benefits of burns for large mammal habitat undermined by large, severe fires in the American West

Ecography, EarlyView.
Escalating wildfire frequency and severity are altering wildland habitats worldwide. Yet investigations into fire impacts on wildlife habitat rarely extend to the macroecological scales relevant to species conservation and global change processes. We evaluate the effects of wildfire on habitat quality and selection by large mammals spanning three ...

Overview of autotoxicity in alfalfa (Medicago sativa L.): Identifying gaps between laboratory findings and demonstration at field scale

Grassland Research
Autotoxicity is a type of intraspecific allelopathy in which compounds released by a plant inhibit the growth of other plants of the same species. In alfalfa (Medicago sativa L.), an herbaceous perennial legume widely used in hay and pasture production ...
