Genetic diversity, gene flow, and landscape resistance in a pond-breeding amphibian in agricultural and natural forested landscapes in Norway
Haugen, Hanne; Dervo, Børre Kind; Østbye, Kjartan; Heggenes, Jan; Devineau, Olivier; Linløkken, Arne N. (Peer reviewed; Journal article, 2023)Genetic diversity is a key part of biodiversity, threatened by human activities that lead to loss of gene flow and reduction of effective population sizes. Gene flow is a result of both landscape connectivity and demographic ... -
Landscape genetics of northern crested newt Triturus cristatus populations in a contrasting natural and human-impacted boreal forest
Haugen, Hanne; Linløkken, Arne; Østbye, Kjartan; Heggenes, Jan (Peer reviewed; Journal article, 2020)Among vertebrates, amphibians currently have the highest proportion of threatened species worldwide, mainly through loss of habitat, leading to increased population isolation. Smaller amphibian populations may lose more ... -
Predicting Habitat Properties Using Remote Sensing Data: Soil pH and Moisture, and Ground Vegetation Cover
Haugen, Hanne; Devineau, Olivier; Heggenes, Jan; Østbye, Kjartan; Linløkken, Arne N. (Peer reviewed; Journal article, 2022)Remote sensing data comprise a valuable information source for many ecological landscape studies that may be under-utilized because of an overwhelming amount of processing methods and derived variables. These complexities, ... -

Rådyrets (Capreolus capreolus) beiteatferd på barlind (Taxus baccata) i Fagerliåsen, Lier.
Sleen, Odin (Master thesis, 2021)Beiteadferden til rådyret (Capreolus capreolus) på den giftige planten barlind (Taxus baccata) er et tema som er lite studert, men det foreligger dokumentasjon på forgiftning hos ulike pattedyr. I Oslo har det blitt påvist ...
