For a diverse pollinator fauna it is important that pollen and nectar are available over the entire summer at spatially relevant scales. Semi-natural hay meadows among most sources of flower resources for pollinators, but strongly affected by timing mowing. Management recommendations often prescribe late mowing on order to allow undisturbed flowering during summer. Traditional practices, however, include also earlier We investigate link between temporal variation traditional practices...

Abstract Questions: How does Calluna vulgaris regenerate after burning wet and dry heaths of different age? Location: Central Norway. Methods: Patches dominated old young heath were burned. The mean temperatures reached in the categories measured. Cover, frequency, height number seedlings studied plots. Results: varied from 680 to 740°C, highest that had not been burned for at least 50 years. Regeneration was evident year burning, but only seeds. Even with a short interval lacked vegetative...

Abstract Questions What are the effects of abandonment on plant diversity in semi‐natural grasslands? Do taxonomic and functional vary along environmental gradients climate soil? Location West mid‐Norway. Methods Plant composition was surveyed 110 subplots 4 m 2 14 sites across grazed abandoned grasslands. Climate data were extracted soil analysed. To reduce number explanatory variables deal with collinearity, we performed PCA. Data species vegetative height (H), leaf dry matter content...

• In Norway the Agri-Environment Scheme The Action Plan for Hay Meadows (APHM) was implemented in 2009. Using an interdisciplinary approach involving ecologists and social scientists, we examined adaptive management APHM. APHM showed to be a success, but perhaps only short term. Safeguarding biodiversity red listed nature type semi-natural hay meadow depend on multiple factors. have allow actions adapted ecological environment also economic, structural environment. Worldwide habitats of high...

Understanding how drivers of change affect ecosystem services (ES) is great importance. Indicators ES can be developed based on biophysical measures and used to investigate the service flow from ecosystems socio-ecological systems. However, concept multivariate use normalized composite indicators reduces complexity facilitates communication between science policy. The aim this study analyze land affects species richness effects are modified by environmental factors using indicators. Using...

Abstract. Land use change can affect biodiversity, and this has an impact on ecosystem services (ESs), but the relationships between biodiversity ESs are complex poorly understood. Biodiversity is declining due to abandonment of extensively grazed semi-natural grasslands. We therefore aim explore provided by managed Focusing vascular plant species richness, as well fodder quantity, quality, stability, allergy control, climate regulation, nutrient cycling, pollination, aesthetic appreciation,...

Species-rich natural and semi-natural ecosystems are under threat owing to land use change. To conserve the biodiversity associated with these ecosystems, we must identify target conservation efforts towards functionally important species supporting habitats that create connections between remnant patches in landscape. Here, a multi-layer network approach connect metanetwork of plant–bee interactions grasslands which hotspots European landscapes. We investigate how landscape connecting...

Grazing is an important management action to conserve biodiversity in semi-natural grasslands but it understand how grazing influences the life-history components and population dynamics of plant species. In this study, we analysed effects intensity abandonment on grassland species Knautia arvensis which nectar source for pollinating indicator agricultural landscapes. We recorded stage, survival, establishment seedlings ramets, number inflorescences marks permanently marked individuals eight...

Space-use by aquatic ectotherms is closely linked to environmental factors such as temperature due thermal-mediated metabolism and energy requirements. These are important, they may alter an animal’s exposure food/predators, hinder physiological function, increase competitive interactions, or even prompt population biodiversity loss. Using general linear mixed-effects models, we investigated the influence of medium-term (months-years) (diel period, water temperature, season, wind speed, air...

Abstract Understanding how aquatic animals select and partition resources provides relevant information about community dynamics that can be used to help manage conservation efforts. The critically endangered hawksbill sea turtle ( Eretmochelys imbricata ) spends an extended part of its juvenile development in coastal waters. A strong proclivity remain resident small areas, often high density, raises questions juveniles including selection habitat spatial overlap among conspecifics. Using...

Primula scandinavica is endemic to Norway and Sweden populations are in decline due changes land use. Future climate change might have an additive effect on its distribution. To predict the future distribution of P. scandinavica, potential suitable habitats with regard use need be investigated. We generated species models (SDMs) both for local (Eastern Jotunheimen) national (Norway) scales projected based predicted change. The best SDM at a scale includes (temperature, precipitation, number...

Abstract Conservation of species associated with semi‐natural grasslands, a threatened habitat, is dependent on their ability to disperse between the few and fragmented patches remaining in landscape. To maintain metapopulations dynamics reduce risk regional extinction, it essential know whether other, more widespread, habitats can act as alternative habitat for biodiversity habitats. Here, we study how four widespread types boreal landscapes—forest, permanent grassland, abandoned grassland...

Early stages of Calluna vulgaris regeneration after burning coastal heaths on Tarva, central Norway

The objective of this pilot study was to compare resource use in a mountainous summer farming landscape between old and modern dairy cow breeds during five-day period. breed used larger part the than breed, most likely due differences habitat patterns. group preferred semi-natural pastures, while overgrown meadows, intermediate fen, wooded grass-rich sub-alpine birch woodland. Both spent time grazing grasses, but showed higher frequency grasses Vaccinium myrtillus its diet, bushes trees....

Semi-natural grasslands are hotspots of biodiversity in Europe and provide amounts flower resources for pollinators. We present data on composition spatial turnover herb species between semi-natural Romania mown at different times during the growth season (early, intermediate, late). The include occurrences, their phenological stage, resources, measures occurrences based Detrended Correspondence Analyses (DCA), start August. dataset is provided as supplementary material associated with...

The effect of climate change on mountain vegetation is influenced by environmental factors and site effects. To monitor the we therefore need to understand species' sensitivity microclimate gradients. objective this study widespread plant temporal spatial variation along gradients in Norwegian mountains a coast–inland gradient. Occurrence abundance species were surveyed 110 plots four at two points time, seven years apart. Of 222 registered, Salix herbacea , Phyllodoce caerulea Carex...
