1. 31. Coral reefs in a human-dominated environment : implications of altered disturbance regimes and reduced resilience

   Författare :Magnus Nyström; Terry Done; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Korallrev; Ekosystem i vatten; Marine Ecotoxicology; marin ekotoxikologi;

   Sammanfattning : Coral reefs are facing an "Anthropocene " era where humans have advanced from a minor species with limited influence on coral reefs to a major source of disturbance. Disturbance arriving from human influences may not only interact with each other, but also with natural disturbance regimes, leading to synergistic effects. LÄS MER

   Sammanfattning : Oak regeneration is thought to be promoted by natural disturbance and past management practices that create semi-open conditions, such as periodic livestock grazing and lowintensity fire. The overall goal of this thesis was to examine whether disturbance factors can promote natural oak regeneration. LÄS MER

7. 35. Disturbance Effects on Plant and Mycorrhizal Communities in Sandy Grasslands

   Författare :Tim Krone Schnoor; Biodiversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Many ecosystems have historically been disturbed, either naturally or as part of a cultural management. Due to loss of species as a result of too little disturbance, disturbance must be considered as a potential tool for conservation and restoration in various ecosystems. In this thesis work, disturbance effects on a grassland system were studied. LÄS MER
