  1. 36. 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.

  2. 37. From behaviour to genes: anti-predator responses of brown trout (Salmo trutta) under winter conditions

    Författare :Karl Filipsson; Eva Bergman; Ann Erlandsson; Martin Österling; Johan Watz; Stefán Óli Steingrímsson; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; burbot; climate change; cortisol; diel behaviour; gene expression; HPI axis; light; mRNA; piscivorous; poikilotherm; predator; salmonid; stream; stress; temperature; thermal; winter behaviour; Biology; Biologi;

    Sammanfattning : Temperature has major effects on the performance of poikilotherms. In encounters with predators, low winter temperatures constrain predator detection and escape capabilities in prey fishes. LÄS MER

  3. 38. 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

  4. 39. Factors influencing the biogeography of bacteria in fresh waters - a metacommunity approach

    Författare :Jürg Brendan Logue; Eva S. Lindström; Silke Langenheder; Lars Tranvik; Byron Crump; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacteria; diversity; richness; community composition; dispersal; metacommunity; fresh water; biogeography; Freshwater ecology; Limnisk ekologi; Microbiology; Mikrobiologi; Biologi med inriktning mot limnologi; Biology with specialization in Limnology;

    Sammanfattning : One of ecology’s primary goals is to comprehend biodiversity and its patterns of distribution over space and time. Since microorganisms play a pivotal role in key ecological processes, the diversity of microbial communities may have important implications for the stability and functioning of Earth’s ecosystems.

  5. 40. Genetic variation and local adaptation in peripheral populations of toads

    Författare :Björn Rogell; Jacob Höglund; Anssi Laurila; Josh Van Bushkirk; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Terrestrial; freshwater and marine ecology; Terrestrisk; limnisk och marin ekologi; Populationsbiologi; Population Biology;

    Sammanfattning : Northern fringe populations generally have low amounts of genetic variation and inhabit habitats where specific adaptations are needed. On the Swedish west coast, the natterjack toad (Bufo calamita) inhabits skerry islands. LÄS MER
