Změny biodiverzity a složení společenstev hmyzu při obnově tropických ekosystémů

Halamová, Pavla

in English Tropical rainforests are the richest habitats, but most endangered habitats on the world as well. Given the current global trend of deforestation, successful restoration of secondary forests is necessary for maintaining the rich fauna and flora of tropical rainforests. Insects are the most diverse group of animals in the tropics and they have crucial roles in an ecosystem functioning. Restoration interventions in degraded forests are nowadays more common and case studies are involving insect communities, however no review of them has been conducted. The aim of this thesis was to summarize the results of hitherto published studies dealing with the insect responses to the restoration of the tropical rainforests. With the emphasis on logged forests and lands converted for agriculture, the insect species richness, abundance, diversity, and the changes of composition were studied. If ecological conditions are suitable, insect species richness, abundance, diversity, and similarity of composition tend to increase towards primary forests for majority of insect groups. However, we observe some differences across groups of insects, based on the type and severity of disturbance, and on specific conditions on the site. Keywords: insect recovery, tropical rainforest, disturbance, species diversity,...
