1. 1. Debugging metabarcoding for insect biodiversity studies

   Författare :Daniel Marquina Hernández; Fredrik Ronquist; Owen Wangensteen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metabarcoding; insects; non-destructive; DNA extraction; Malaise trap; preservative ethanol; environmental DNA; systematisk zoologi; Systematic Zoology;

   Sammanfattning : Insects are one of the most abundant and diverse animal groups, and they include many valuable ecological indicator species, but taxonomic discovery projects and biodiversity surveys targeting this group are often challenging. While mass trapping devices allow the collection of insects in great numbers, the task of identifying the species present is a painstaking and resource-demanding process. LÄS MER

3. 2. Functional diversity of zooplankton in marine food webs : Integrating DNA metabarcoding and network modeling

   Författare :Andreas Novotny; Monika Winder; Catherine Legrand; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plankton; Food-Webs; DNA metabarcoding; Marine; Baltic Sea; Marine Ecology; marin ekologi;

   Sammanfattning : The oceans are important regulators of the Earth’s climate system by sequestering carbon from the atmosphere taken up by primary producers. Zooplankton, including protozoans and metazoans of different phyla and size classes, occupies several trophic niches and regulates energy flow between primary producers and fish. LÄS MER

4. 3. Environmental sequencing to infer patterns of eukaryotic evolution : Combining long-read and short-read metabarcoding

   Författare :Mahwash Jamy; Fabien Burki; Micah Dunthorn; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protists; eukaryotes; environmental sequencing; ribosomal DNA; PacBio; long-read metabarcoding; phylogenetics; salt barrier; habitat evolution; eukaryotes evolution; evolutionary rate; Apicomplexa; pathogen; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

   Sammanfattning : Our view of eukaryotes is biased towards plants, animals, and fungi. But the vast majority of eukaryotic diversity is microbial in nature. These microbial eukaryotes are key players in all ecosystems on earth and are collectively known as protists. LÄS MER

5. 4. Forests, Functions, and Food Webs : Riparian processes through an ecological and molecular lens

   Författare :Jeffery Marker; Eva Bergman; Rolf Lutz Eckstein; Denis Lafage; Rachel E. Bowes; Ann Erlandsson; John S. Richardson; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Riparian systems; functional diversity; stable isotope analysis; metabarcoding; Tetragnathidae; Lycosidae; forestry management; prey subsidies; Biology; Biologi;

   Sammanfattning : Riparian systems are critical ecological interfaces that have a significant impact on the surrounding aquatic and terrestrial ecosystems. The riparian and surrounding systems have significant roles in regulating energy flow, providing essential nutrients, and supporting unique species, making them important for ecosystem function.

7. 5. The Ecological Role of Roadside Stormwater Ponds - Potential to Support Biodiversity

   Författare :Zhenhua Sun; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Macroinvertebrates; Stormwater ponds; DNA metabarcoding; Sediments; High throughput sequencing; Road runoff; Water quality; Aquatic biodiversity;

   Sammanfattning : The increased recognition that roads may impair the aquatic environment and ecosystems has led to a shift from conventional drainage systems toward blue-green solutions such as stormwater ponds. Research on blue-green stormwater solutions has until now mainly focused on water quantity and quality. LÄS MER
