1. 21. Characterization of the ocelli of the migratory Bogong moth (Agrotis infusa) in comparison to the non-migratory Turnip moth (Agrotis segetum)

   Master-uppsats, Lunds universitet/Examensarbeten i biologi

   Författare :Denis Vaduva; [2016]
   Nyckelord :Biology and Life Sciences;

   Sammanfattning : The Bogong and Turnip moths are two species of the genus Agrotis, similar in size, but different in life style. The Bogong moth is a long distance migratory species endemic to Australia, whereas the Turnip moth has a wide spread in Africa, Europe and Asia where it is considered a pest. LÄS MER

   Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :Carolina Gavell; Anna Olofsson; [2016]
   Nyckelord :vårväder; rådjur; medeltemperatur; nederbörd; kidöverlevnad;

   Sammanfattning : Rådjuret (Capreolus capreolus) är ett av de mest spridda hjortdjuren och återfinns i nästan hela Europa. I Sverige är rådjuret ett av det mest jagade vilten. Lamningen sker i slutet av maj och i juni med en topp mellan 25:e maj och 7:e juni. Mortaliteten hos kiden är hög under den första levnadsmånaden. LÄS MER

4. 23. Effects of local habitat characteristics and landscape composition on the occurrence of burnet moths.

   Master-uppsats, Linköpings universitet/Biologi

   Författare :Yana Tarasova; [2016]
   Nyckelord :Zygaena; burnet moths; habitat quality; landscape; conservation; semi-natural grasslands; forests; matrix;

   Sammanfattning : A decline in biodiversity in agricultural landscapes has been reported for decades. One of the most important habitats for biodiversity in agricultural landscapes is semi-natural grasslands. To preserve species-rich semi-natural grasslands, research need to focus both on local habitat quality and on landscape composition at various scales. LÄS MER

5. 24. Standardization of the Compass Neuropils of the Australian Bogong Moth, Agrotis infusa

   Kandidat-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

   Författare :Liv de Vries; [2016]
   Nyckelord :Biology and Life Sciences;

   Sammanfattning : Every summer the Australian Bogong moth migrates from southern Queensland to the Australian Alps in southern New South Wales. Other migrants such as the monarch butterfly use a time-compensated sun compass. However, the Bogong is nocturnal and only has access to skylight cues such as the moon, polarized light or the Milky Way. LÄS MER

7. 25. Biology of the diamondback moth (Plutella xylostella) and its future impact in Swedish oilseed rape production : a literature review

   Kandidat-uppsats, SLU/Dept. of Ecology

   Författare :Joakim Hermansson; [2016]
   Nyckelord :diamondback moth; Plutella xylostella; overwintering; climate; canola; oilseed rape; cosmopolitan pest; resistance; Brassica napus;

   Sammanfattning : The biology of the Diamondback moth, Plutella xylostella, and its impact on oilseed rape production is reviewed. The Diamondback moth, DBM, is a serious, migratory, pest and a problem worldwide because its larval stage has a ravenous appetite, which causes major economic losses in Brassica crops. LÄS MER
