  3. 2. En inventering av bottenfauna i Trönningeån med två biflöden

    Kandidat-uppsats, Högskolan i Halmstad

    Författare :Johannes Glännman; Kalle Ström Töttrup; [2022]
    Nyckelord :Bottenfauna; Trönningeån; ekologi;

    Sammanfattning : Benthic macroinvertebrates are usually small animals living in our lentic and lotic ecosystems, they have been used as indicators of water quality and biodiversity for a long time. Dam removals have become one of the “go-to” conservation methods for restoring connectivity in lotic ecosystems and thereby enabling passage upstream for migrating species. LÄS MER

  4. 3. Simulating Facilitation in a Spiking Neural Network

    Kandidat-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

    Författare :Alexander Kuzmin; [2020]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Many insects are able to detect, isolate and track small targets that move quickly against a dynamic background. This ability is enabled by a group of neurons called small target motion detectors (STMD). These neurons, among other properties, have a type of short term memory called response facilitation.

  5. 4. Study on biomass in semiaquatic insects (Odonata) over a 20-year period in central, Sweden.

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Andreas Zsoldos; [2018]
    Nyckelord :Biomass; Odonata; Aesnidae; Libelluidae;

    Sammanfattning : This study is about how biomass of dragonflies insects have changed over the past 20-years in a forested area of central Sweden. This was done by analysing previously collected Odonata larvae stored in ethanol where sampling effort corrects the weight per locality. LÄS MER

  7. 5. The environmental and anthropogenic impact onfreshwater biodiversity in Lajeado, RS, Brazil. : A study of using dragonflies as indicators for theenvironmental status in freshwater biomes

    M1-uppsats,

    Författare :Philip Sjöwall; Robert Lundström; [2016]
    Nyckelord :Dragonlfies; freshwater; Braszil;

    Sammanfattning : Fragmentation of the Atlantic rainforest and alteration of waters due to agricultural expansion hasgreatly affected the species diversity in Brazil. In this study, we investigate how different environmental factors affect dragonfly communities and dragonfly species richness in sixteen different locations in Rio Grande do Sul, Brazil. LÄS MER
