In this article, we present an individual-based model (IBM) investigating the proximate mechanisms behind phenotypes “boldness” and “fearfulness” in songbirds.
A report written by Ingrid Vaksvik This study explores the interactions between domestic herbivores and beetles in the fjord system of the Nordhordland Biosphere Reserve. Fields grazed by sheep had overall higher beetle abundance,...
Hoverflies (Syrphidae) are a family of flies of the Diptera order that provide a range of ecological services to agriculture. This report gives an overview of what hoverflies are, their importance to agriculture, and subsequently what services they provide to aid pollination and ecosystems. A description of species diversity, abundance, and phenology in inner Hardanger is provided.
Det er funnet at Norge lagrer store mengder karbon, men det er gjort lite kartlegging av Soil organic carbon (SOC) og karbon i biomasse over bakken på lokalt nivå (Bartlett et al., 2020). Denne studiens formål er å kartlegge SOC og karbon i biomassen over bakken i naturtyper i Bergen og omegn. Vi tar for oss tre naturtyper i fastlands-Norge. Disse er skog hvor gran, furu, eik og andre løvtrær dominerer, åpent lavland slik som gressmark, jordbruksareal og lynghei, og våtmark som myr og torvmark.
Human activities keep exploiting lands to the detriment of biodiversity and species that are declining, owing to this habitat loss. Hence, understanding what use a species makes of its habitat contributes to preserving the species by establishing conservation strategies. We studied the habitat uses and winter behaviour of a coastal population of black grouse (Lyrurus tetrix) during winter 2021-2022 in the heathlands of Lygra, a coastal island in western Norway.
Insects are critical for human welfare and a decrease in insect populations is expected to have great consequences. Understanding exactly in which ways insect populations have changed recently may be more complicated than previously assumed.
Why sex? Perhaps the simplest, yet deepest, question about sexual reproduction is why it exists at all. The answer seems obvious at first, to produce offspring. On second thought however, the question becomes far more intriguing.
