Crustacean zooplankton trophic position, food item origin and relationship to fish in the temperate, subalpine Lake Savalen, central Norway, compared with similar lake ecosystems.
(Peer reviewed; Journal article, 2021)Lake Savalen is a subalpine, oligotrophic, dimictic and regulated lake situated in Norway, north Europe. It is located between 703-708 meters above sea level in the central part of Norway. The lake has a maximum surface ... -
Culture dependent and independent analyses suggest a low level of sharing of endospore-forming species between mothers and their children
(Peer reviewed; Journal article, 2020)Spore forming bacteria comprise a large part of the human gut microbiota. However, study of the endospores in gut microbiota is limited due to difficulties of culturing and numerous unknown germination factors. In this ... -
A culture-, amplification-independent, and rapid method for identification of pathogens and antibiotic resistance profile in bovine mastitis milk
(Peer reviewed; Journal article, 2023)Introduction: Rapid and accurate diagnosis of causative pathogens in mastitis would minimize the imprudent use of antibiotics and, therefore, reduce the spread of antimicrobial resistance. Whole genome sequencing offers a ... -
Day versus night use of forest by red and roe deer as determined by Corine Land Cover and Copernicus Tree Cover Density: assessing use of geographic layers in movement ecology
(Peer reviewed; Journal article, 2022)Diel use of forest and open habitats by large herbivores is linked to species-specific needs of multiple and heterogeneous resources. However, forest cover layers might deviate considerably for a given landscape, potentially ... -
The declining occurrence of moose (Alces alces) at the southernmost edge of its range raise conservation concerns
(Peer reviewed; Journal article, 2021)The border region between Austria, the Czech Republic, and Germany harbors the most south-western occurrence of moose in continental Europe. The population originated in Poland, where moose survived, immigrated from former ... -
Demography of a Eurasian lynx (Lynx lynx) population within a strictly protected area in Central Europe
(Peer reviewed; Journal article, 2021)Large carnivores promote crucial ecosystem processes but are increasingly threatened by human persecution and habitat destruction. Successful conservation of this guild requires information on long-term population dynamics ... -
Determining Statistically Robust Changes in Ungulate Browsing Pressure as a Basis for Adaptive Wildlife Management
(Peer reviewed; Journal article, 2021)Ungulate browsing has a major impact on the composition and structure of forests. Repeatedly conducted, large-scale regeneration inventories can monitor the extent of browsing pressure and its impacts on forest regeneration ... -
Diameter growth of trees in miombo and acacia woodland in an eroded landscape in NE Tanzania
(Peer reviewed; Journal article, 2022)Diameter increment of trees typical of miombo and acacia woodland was studied during a period of 20 years in Kondoa district, Tanzania. The study was performed in permanent plots in a severely degraded area subjected to ... -
Displacement Effects of Conservation Grazing on Red Deer (Cervus elaphus) Spatial Behaviour
(Peer reviewed; Journal article, 2022)Conservation grazing uses semi-feral or domesticated herbivores to limit encroachment in open areas and to promote biodiversity. However, we are still unaware of its effects on wild herbivores. This study investigates the ... -
DNA metabarcoding reveals the importance of gelatinous zooplankton in the diet of Pandalus borealis, a keystone species in the Arctic
(Peer reviewed; Journal article, 2021)Information about the dietary composition of a species is crucial to understanding their position and role in the food web. Increasingly, molecular approaches such as DNA metabarcoding are used in studying trophic ... -
Effects of experimental rewilding on butterflies, bumblebees and grasshoppers
(Peer reviewed; Journal article, 2022)Grassland ecosystems are species-rich habitats that are rapidly declining globally posing serious concerns for biodiversity conservation. This situation is particularly relevant in agricultural areas in Europe. As traditional ... -
Effects of forestry intensification and conservation on green infrastructures: A spatio-temporal evaluation in Sweden
(Peer reviewed; Journal article, 2021)There is a rivalry between policies on intensification of forest management to meet the demands of a growing bioeconomy, and policies on green infrastructure functionality. Evaluation of the net effects of different policy ... -
The Effects of Growth Regulators and Apical Bud Removal on Growth, Flowering, and Corms Production of Two Gladiolus Varieties
(Peer reviewed; Journal article, 2022)Gladiolus is commonly propagated from corms. The multiplication rate of corms is low and to increase the propagation rate, we examined a combination of apical bud removal and the application of growth regulators. The ... -
