. A new study developed at Estación Biológica de Doñana (CSIC) has employed genomic data to infer the consequences of dispersal-related trait variation in short-winged and long-winged forms of the taxonomically controversial Corsican grasshopper (Chorthippus corsicus).

Conservation plans can be greatly improved when information on the evolutionary and demographic consequences of habitat fragmentation is available for several codistributed species. Here it has been studied the spatial patterns of phenotypic and genetic variation among five grasshopper species that are codistributed across a network of microreserves but show remarkable differences in dispersal-related morphology, degree of habitat specialization and extent of fragmentation of their respective...
