Fragmented habitats may need to be better connected than previously thought

A model study reveals that the seeds of plants in small, fragmented habitats can abruptly evolve in such a way that they can no longer travel long distances. As a consequence, plants are less successful in reaching other habitats. This insight shows that fragmented natural areas may need to be better connected than previously assumed. The research, conducted by biodiversity researchers Monique de Jager and Merel Soons , was published yesterday in the scientific journal Ecology and Evolution. Habitat fragmentation is a major cause of global biodiversity loss. Populations of plants and animals residing in small habitats are more vulnerable and face an increased risk of extinction. Moreover, fragmentation makes plants and animals less successful in returning to places from where they have disappeared.
