  1. 1. Challenges in a changing climate : The effect of temperature variation on growth and competition in damselflies

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Kim Lea Holzmann; [2022]
    Keywords : ecology; climate change; thermal variation; competition; cannibalism; damselfly;

    Abstract : Climate change is affecting biodiversity on multiple levels all over the world. Concomitant with a higher mean temperature, an increased amplitude of temperature variation is predicted. READ MORE

  2. 2. The effect of temperature on the interaction between larvae of a native and a range expanding dragonfly species

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Sanne Everling; [2021]
    Keywords : Climate change; temperature; native; invasive; competition; behaviour; Odonata;

    Abstract : Climate change might affect the distribution of species; therefore, it is important to anticipate the imminent impact of climate change. Even though climate responses have the potential to affect species interactions, most models on the effect of climate change on species distribution assume that species respond to climate individually.

  3. 3. Effects of native freshwater mussels and leaf debris on benthic macroinvertebrate abundance and diversity : A field experiment with Margaritifera margaritifera in Vasslabäcken, Örebro county

    University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Author : Kai Sven Onken; [2021]
    Keywords : bivalve; functional role; habitat modification; decomposition; biodeposition;

    Abstract : Organisms that are part of complex ecosystems interact not only with other organisms but also with their environment, affecting ecosystem functions. In aquatic ecosystems filter feeders affect ecosystem functioning by transferring energy and nutrients from the water to the benthos. READ MORE

  4. 4. Host plant selection in closely related butterfly species due to reproductive interference: Modelling a tritrophic system

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Alexandros Bantounas; [2021]
    Keywords : reproductive interference; habitat selection; modelling; phytophagous insects;

    Abstract : Host plant selection is an important process during the life cycle of lepidopterans, providing ovipositing sites for adults and food resources for the larvae. The processes behind host plant selection have been extensively studied, especially in closely related species in the context of niche separation. READ MORE

  5. 5. Effects of nitrogen quality and quantity on weed-crop competition : a greenhouse experiment with Avena sativa and Avena fatua

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Lukas Hallberg; [2019]
    Keywords : weed-crop competition; resource pool diversity; soil microbes; weed community;

    Abstract : The intensification of agricultural activities has provided unprecedented increases in crop production. In the light of this development concerns have been raised about its negative environmental impact. High-input farm management has further reduced the weed diversity and shaped weed communities to consist of a few highly competitive weed species. READ MORE
