Modeling effects of crop production, energy development and conservation-grassland loss on avian habitat.

PLoS ONE, 2019
Birds are essential components of most ecosystems and provide many services valued by society. However, many populations have undergone striking declines as their habitats have been lost or degraded by human activities.

Nestling condition of a grassland bird is not associated with food availability in restored grasslands

Avian Conservation and Ecology
Grassland bird populations have experienced steep declines in recent decades, necessitating better understanding of factors affecting their reproductive success. Grasslands are highly variable environments, and such variation affects the diversity and abundance of arthropods, which constitute the diet for most nestling grassland songbirds.

Three grassland bird species’ responses to fire and habitat structure in southern Illinois, USA suggest broad benefits of grassland size and plant diversity

Avian Conservation and Ecology, 2023
Grassland birds are the most rapidly declining bird guild in North America, largely due to extensive habitat loss and fragmentation. Because many grassland bird species have different habitat preferences, managing grasslands to provide habitat for a ...

Effects of Livestock Grazing Management on Grassland Birds in a Northern Mixed-Grass Prairie Ecosystem [PDF]

, 2019
Grassland birds have undergone substantial population declines throughout much of their historic ranges in North America. Most of the remaining grassland bird habitat is restricted to rangelands managed for livestock production, so grazing management has

Weather influenced nestling growth of an insectivorous but not a granivorous grassland passerine in Argentina

Avian Research
Nestling growth of birds can be affected by weather fluctuations. In general, it is expected that higher temperatures favor growth by improving food availability and nestling metabolism, while rain hinders it by reducing foraging efficiency.

Threats and opportunities for European grassland areas under different market and policy scenarios

, 2014
Grasslands are an important landscape element in Europe, but have seen a reduction in area in the last 50 years. To assess future changes under varying price and policy scenarios the FARMIS agri-sector model was utilised to model likely farmer behaviour ...
