Background Tall fescue (Festuca arundinacea Schreb.) is an important cool‐season perennial grass. Its persistence and forage yield can be severely affected by drought stresses during the hot, dry summers of the southern USA.

Development of Future Habitat Suitability Models for the Swift fox (Vulpes velox) in the American Southwest [PDF]
The Swift fox (Vupes velox) is a habitat specialist species of short or mixed grass prairie. We used bioclimatic envelope models and habitat suitability models under three future climate scenarios (based on CO2 emission rates) from "www ...

Abstract The effects of the Younger Dryas (YD) fluctuation on Late Pleistocene hunter‐gatherers' settlement and subsistence systems in the southern Alps are poorly known. This is primarily due to the scarcity of archaeological sites dating from the YD, in contrast with the extensive evidence available from the lateglacial interstadial and the early ...

Prevailing agricultural systems dominated by annual crop monocultures, and the landscapes that contain them, lack resilience and multifunctionality. They are vulnerable to extreme weather events, contribute to degradation of soil, water, and air quality,

Grass functional traits reflect the long history of fire and grazers in the savannas of Texas
Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

Functional profiles of soil microbial communities in the alpine and temperate grasslands of China
Grassland ecosystems in cold regions are typical of short growing seasons and limited primary productivity, rendering soil microorganisms as major ecosystem engineers in governing biogeochemical cycling.

Organic grassland: the foundation stone of organic livestock farming [PDF]
In organic farming, the components of the whole farm system interact closely and grassland plays the central role in this intricate web, including the arable cropping phase.

Abstract Premise Many angiosperms have evolved specialized systems that promote pollination by specific taxa. Therefore, plant distributions may be limited by the local abundance of their specialist pollinators. In eastern North America, Lobelia cardinalis is thought to be pollinated solely by Archilochus colubris, the only hummingbird species found in

Spatial variation of grassland canopy affects soil wetting patterns and preferential flow
Spatially heterogeneous canopy and pre‐event soil moisture conditions changed soil‐wetting patterns. Taller grass, together with drier soil, weakens soil moisture response, probably because of uneven water input and dryness induced preferential flow. Abstract Canopies shape net precipitation patterns, which are spatially heterogeneous and control soil ...
