Historic and current land-use changes have altered the landscape for grassland biota, with
over 90% of grasslands and savannas converted to agriculture or some other use in north …

The predictability of the physical arrangement of plants, at whatever scale it is viewed, is
referred to as a spatial pattern. Spatial pattern is a crucial aspect of vegetation that has …

We conducted a factorial field experiment in order to investigate the role of the soil seed
bank in gap recolonization in a calcareous grassland, using 240 experimental gaps (10× 10 …

Natural disturbances affect spatial and temporal heterogeneity in plant communities, but
effects vary depending on type of disturbance and scale of analysis. In this study, we …

Ecosystem engineering—the physical modification of habitats by organisms—can create
patches with altered species richness relative to adjacent, unmodified patches. The effect of …

Large grazing mammals contribute to the species diversity of grasslands via direct and
indirect effects of defoliation and urine deposition. We examined the influence of one and …

We measured productivity and diversity of annual plant communities in human—made pits
and mounds (20° 30° 100 cm) in the Northern Negev of Israel. We differentiated the species …

Soil pH was measured at two different spatial scales in coastal dunes on Norderney, North
Sea, and in Mecklenburg-Vorpommern, Baltic Sea, Germany. Relationships between the …

Ecosystem engineers have important effects on abundance and diversity of organisms and
are vital for conservation efforts. Some large mammalian grazers are engineers because …

Historically, diversity in a community was often believed to result primarily from local
processes, but recent evidence suggests that regional diversity may strongly influence local …
