Grazing networks promote plant functional connectivity among isolated grassland communities
Abstract Aim Habitat loss threatens plant diversity globally. Lack of plant functional connectivity between isolated populations is often pinpointed as one of the major underlying mechanisms driving subsequent species extinctions. Therefore, landscape‐scale conservation management promoting function...
