Fragmentation genetics in tropical ecosystems: from fragmentation genetics to fragmentation genomics

Tropical regions are experiencing unprecedented economic and population growth. This goes hand in hand with increase habitat fragmentation of tropical ecosystems. Understanding the genetic consequences of these spatial and temporal changes across landscapes is critical to conservation of the vast majority of global biodiversity. This virtual issue of Conservation Genetics, presents six empirical and one review paper showcasing fascinating and important findings with regard to how habitat fragmentation impacts on genetic diversity in rare or endangered tropical species. The message from these papers is clear, fragmentation has a number of serious genetic consequences, which can contribute to undermining the viability of species in fragmented landscapes. Conservation genetics provides a powerful tool to inform both conservation and management of species and genetic resources. But, careful consideration is needed to ensure studies apply appropriate sampling designs and genetic analysis to better test hypothesis. Next generation genomics offers great opportunities to provide even more answers and greater resolution of the consequences for adaptive genetic variation, to ensure future tropical landscapes are resilient.
