3. 2. Effects of past fragmentation and habitat loss and current management methods on the changes in vascular plant communities. : An evaluation of extinction debt in semi-natural grasslands in Sweden

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Adina Sennblad; [2021]
   Keywords : ;

   Abstract : Habitat loss and fragmentation are believed to be two of the main reasons for high extinction rates of species, resulting in decreased biodiversity. According to the island biogeography theory, the species richness in a patch, here a semi-natural grassland, is dependent on the landscape composition, and therefore changes in the landscape composition will result in changes in the species richness of the grassland.

6. 5. The Molecular Diversity and Biogeography of Tardigrades

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Irina Schuman; [2017]
   Keywords : molecular diversity; biogeography; tadrigrades; tardigrada;

   Abstract : Tardigrades can handle extreme conditions such as heat, cold and drought, thanks to a process called cryptobiosis which can be found in a limited amount of taxa on Earth. More knowledge about such animals may help us to understand the potential and limitations of life both on Earth and possibly in space. READ MORE
