1. Animal personality in ants : Does the red wood ant (Formica rufa) express personality traits?
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : A recent theory within behavioural ecology suggests that some animal behaviour traits are consistent over time and over different contexts as part of an animals’ “personality”. Animal personality has generally been accepted within vertebrates, but the idea of invertebrates expressing personality has long been meet with scepticism. LÄS MER
2. Putting behavioral assays on fish to the test: Are sociality and scototaxis trials relevant in the wild?
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Animal behavior has become a frequently used tool in modern ecology and ecotoxicology, where laboratory behavioral traits are recognized as sensitive endpoints for assessing natural behavior or non-lethal effects of pollutants on animals. Within these research fields, behavioral traits measured in laboratory environments have been used to formulate predictions of ecological consequences that accompany specific behavior. LÄS MER
3. Bubbles guide migrating smolts around hydropower plants
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : The development of hydroelectric power production and the damming of water courses that ensues causes a threat to the migration patterns of Atlantic salmon (Salmo salar), by altering their habitat and compromising river connectivity. Because the species’ survival heavily depends on the completion of their migration between rivers and oceans, the design of guidance structures that promote successful passages around dams is a critical goal.

4. A study of the behavioural responses in AB, Spd and selectively bred strains of zebrafish
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : The purpose of this study was threefold: to determine if personality is inheritable through selection, to evaluate if discernable differences in behavioral profiles exist between strains and to gauge the effect that chronic stress has on personality development. This investigation was fundamentally a behavioral study, where three behavioral models were used to evaluate these parameters. LÄS MER
5. Effects of triclopyr on wood ants (family Formica)
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Chemical pollutants are one of the main threats against biodiversity and chemicals affecting non-target organisms are of great environmental concern. The herbicide triclopyr is commonly used to keep weeds under control and is believed to be weakly toxic to animals and only lethal in high doses. LÄS MER
