Summary•Genetic diversity is an important

component of biodiversity

•It provides adaptation potential to new environmental conditions

•Conservation has often been neglected geographical patterns in genetic diversity

•However, there is a remarkable increase in research on conservation genetics

Are the main threats to biodiversity also affecting genetic diversity?

Habitat fragmentation, degradation and loss

Water, air and soil pollution

Species introductions

Climate change

Snags vs. logs

Summary•Deadwood is fundamental for biodiversity,

but has been often reduced by mankind

•It provides habitat for many fungal, lichen and bryophyte, arthropod, mammal and bird species

•Variable types of deadwood are needed for different saproxylic (deadwood-dependent) species

•Both downed and standing deadwood are important
