1. 1. Eco-evolutionary processes and community patterns--- novel avenues for studying biodiversity across spatial and temporal scales

   Författare :Yun-Ting Jang; Evolutionär ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Eco-evolutionary dynamics; Community diversity patterns; Spatial phylogenetic patterns; Adaptive dynamics; Elevational diversity gradients; Theoretical ecology; Simulation models; Predation; Competition;

   Sammanfattning : Understanding biodiversity patterns poses a persistent challenge due to the complex interconnections of ecological and evolutionary processes. The particular difficulty comes from the various processes influencing biodiversity patterns across different spatial scales. LÄS MER

3. 2. Biodiversity patterns and the processes regulating them along elevation gradients in the Swedish mountains

   Författare :Johannes Måsviken; Love Dalén; Anne Bjorkman; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biodiversity; elevation gradients; spiders; insects; plants; latitude; altitude; alpha diversity; beta diversity; taxonomic diversity; phylogenetic diversity; functional diversity; Systematic Zoology; zoologisk systematik och evolutionsforskning;

   Sammanfattning : Biodiversity describes the total variation of life and includes the taxonomic, genetic, and phenotypic differences among organisms. Variations of biodiversity in space and time may be driven by ecological, evolutionary, or neutral processes. LÄS MER

4. 3. Plant community assembly and biodiversity: a spatio-temporal perspective

   Författare :Oliver Purschke; Biodiversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phylogenetic diversity; null model; life-history traits; land use history; landscape fragmentation; dispersal; functional diversity; semi-natural grasslands;

   Sammanfattning : Biodiversity, the variety of life at all organisational levels from genes to ecosystems, affects ecosystem processes and therefore the goods and services ecosystems provide. More research is needed to provide new insights into biodiversity changes and the processes that drive these changes, in order to formulate effective policy and conservation measures to stop the ongoing biodiversity loss.

5. 4. Causes and consequences of spatial genetic variation in two species of scleractinian coral in East Africa : Levels of genetic differentiation and intraspecific diversity of Pocillopora damicornis and Platygyra daedalea

   Författare :Petra Souter; Mats Grahn; Bertil Borg; Karen Miller; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; population genetics; corals; Kenya; Tanzania; Functional Zoomorphology; funktionell morfologi;

   Sammanfattning : The work presented in this thesis is a study of the spatial genetic structure of two species of scleractinian corals, Pocillopora damicornis and Platygyra daedalea. The overall objective was to investigate the current capacity of MPAs to preserve and restore coral reefs and to contribute information to improve management decisions. LÄS MER

7. 5. Fungal communities of West African ectomycorrhizal woodlands

   Författare :Brendan R. Furneaux; Martin Ryberg; Matthew Smith; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ectomycorrhizal fungi; West Africa; metabarcoding; Sudanian woodlands; community ecology; ethnomycology; edible mushrooms; fungi; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

   Sammanfattning : Ectomycorrhizal symbiosis is a widespread mutualist relationship between fungi and plants, often trees. It is most well-known in temperate and boreal forests, but also occurs in a variety of tropical ecosystems, including Sudanian savanna woodlands and gallery forests in West Africa. LÄS MER
