1. 1. Mussels in deep water with climate change: Spatial distribution of mussel (Mytilus galloprovincialis) growth offshore in the French Mediterranean with respect to climate change scenario RCP 8.5 Long Term and Integrated Multi-Trophic Aquaculture (IMTA) using Dynamic Energy Budget (DEB) modelling

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Victoria Persson; [2022]
   Keywords : Geography; Geographical Information Systems; GIS; Physical Geography; Mediterranean; Mytilus galloprovincialis; Dynamic Energy Budget; DEB; growth rate; France; mussel cultivation; mussel farming; offshore; aquaculture; climate change; Integrated Multi-Trophic Aquaculture; IMTA; Earth and Environmental Sciences;

   Abstract : Victoria Persson Abstract Mussel cultivation is a sustainable type of food production that may help mitigate the nutritional needs of a future world population of 10-12 billion in 2100. The demand for mussels on the French market is increasing but the production is saturated due to a lack of space for expanding the cultivation close to shore. READ MORE

3. 2. Människa-elefant konflikter : hanteringsstrategier och deras inverkan på människa och elefant

   University essay from SLU/Dept. of Animal Environment and Health

   Author : Hannah Norman; [2019]
   Keywords : elefant; människa; konflikt; bevarandebiologi; hanteringsstrategier;

   Abstract : Nutidens största levande landdjur är elefanten som finns både i Afrika och Asien. Afrika har en population på ca 415 000 ± 20 000 individer distribuerat över 37 länder och den asiatiska elefanten har en uppskattad populationsstorlek på 38 000-52 000 individer i det vilda distribuerat över 13 asiatiska länder.

4. 3. Explaining population size of the saproxylic beetle Prionus coriarius as a function of available dead wood resources

   University essay from SLU/Dept. of Plant Breeding (from 130101)

   Author : Isak Sarac; [2016]
   Keywords : pheromone; coleoptera; cerambycidae; dispersal; threshold; conservation;

   Abstract : Dead wood is an important substrate for many forest bound species including the large group of dead wood associated (saproxylic) beetles. Saproxylic beetles have species specific substrate requirements, that may vary according to factor such as tree species, object type, trunk diameter and decomposition stage. READ MORE

5. 4. Ecologically viable population sizes: Determining factors

   University essay from Institutionen för fysik, kemi och biologi

   Author : Stefan Sellman; [2010]
   Keywords : assembly model; ecologically effective populations; extinction; keystone species; MEVP; MVP; species interactions;

   Abstract : The minimum ecologically viable population size (MEVP) of a species describes the minimum size at which the species itself or another species in the same ecosystem goes extinct as a result of the loss of inter-specific interactions. The MEVP shows a good potential for use as a tool for exploring the mechanisms behind species extinctions, but presently only a small amount of research has been done that takes advantage of this.

6. 5. Minimum Ecologically Viable Populations : Risk assessment from a multispecies perspective

   University essay from Institutionen för fysik, kemi och biologi

   Author : Torbjörn Säterberg; [2009]
   Keywords : Ecological effective population size; extinction; minimum viable population; multispecies modeling; population viability analysis;

   Abstract : The extinction risk of threatened species has traditionally been assessed by the use of tools of Population Viability Analysis (PVA). Species interactions, however, have seldom been accounted for in PVA:s. The omission of species interactions in risk assessments may further lead to serious mistakes when setting target sizes of populations. READ MORE
