Conservation Units

2022
AbstractIn this chapter, we discuss the importance of and methods for delineating conservation units, including species and intraspecific units (e.g., evolutionarily significant units and management units). It is essential to conserve all levels of biodiversity, including genes, populations, species, and ecosystems, for effective biodiversity ...

Integrative approaches to guide conservation decisions: Using genomics to define conservation units and functional corridors

Molecular Ecology, 2018
Climate change and increasing habitat loss greatly impact species survival, requiring range shifts, phenotypic plasticity and/or evolutionary change for long‐term persistence, which may not readily occur unaided in threatened species. Therefore, defining
