  1. 41. Omnivore population dynamics and trophic behavior : applications for sustainable willow short rotation coppice

    Författare :Anna-Sara Liman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Plant traits can mediate the interactions between plant feeding trophic omnivores and their herbivore prey via density effects and by altering the omnivore’s trophic behavior (plant vs. prey feeding). LÄS MER

  3. 42. Seasonal interactions between oaks and insects : evolutionary adaptations and predictions for climate change

    Författare :Adam Ekholm; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Many species are expected to advance their phenology in response to global warming. As some interactions are dependent on the interacting species being synchronized in time, it is important to assess whether species shift their phenology in synchrony or not. LÄS MER

  4. 43. Neurons and glia in the peripheral nervous system : interactions in health and disease

    Författare :Filipa Bouçanova; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The peripheral nervous system (PNS) is composed of nerves and ganglia that connect the brain and the spinal cord (the central nervous system, CNS) to the outside world. The nerves contain the extensions (axons) of both sensory and motor neurons, which allow us to detect and respond to different stimuli. LÄS MER

  5. 44. Unravelling the feeding habits of fungivores : interactions between soil fauna and ectomycorrhizal fungi

    Författare :Cecilia Remén; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The aim of this project was to investigate and clarify the feeding habits of fungivorous soil fauna, with the overall objective of improving our understanding of their functional roles in the ecosystem. Special focus was given to symbiotic ectomycorrhizal (EM) fungi, that, owing to their abundance and diversity, are considered to constitute an important food source for fungivorous soil fauna and may be a factor regulating these faunal communities.

  7. 45. Summer cyanobacterial blooms in the Baltic Sea - implications for copepod recruitment

    Författare :Hedvig Hogfors; Sture Hansson; Wim Kimmerer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; Calanoid copepods; Food web interactions; Harmful algae blooms; Zooplankton; Nodularin; Allelopathy; Baltic Sea; Biochemical markers; RNA-based indices; Acidification; Global Climate Change; Marine Ecology; marin ekologi;

    Sammanfattning : During summer, the Baltic Sea is subjected to the world’s largest cyanobacterial blooms. These blooms are linked to eutrophication and raise many questions concerning their effects on the ecosystem. To understand their impacts on the food web dynamics, it is essential to assess growth responses of grazers to these cyanobacteria. LÄS MER
