Pottiaceae underfamilj Trichostomoideae i Skåne

Pottiaceae subfam. Trichostomoideae in Scania, S Sweden – The members of Pottiaceae subfam. Trichostomoideae excluding Weissia spp. in the province of Skåne (Scania), southern-most Sweden, has been revised based on vouchers collected during the ongoing inventory of the bryophyte flora of the province. In addition, all available earlier records have been compiled and are presented for comparison (b

Organic amendment and fungal species in combination can alter collembolan fitness

Organic material of different origin is commonly used as fertiliser in agricultural practices. Clover and wheat straw are here used to determine the importance of organic amendment for population development of fungal feeding collembolans. Two fungal species, Alternaria infectoria and Mucor hiemalis, were inoculated in three growth substrates, clover amended soil, straw amended soil and non-amende

Divergent composition but similar function of soil food webs of individual plants: plant species and community effects

Soils are extremely rich in biodiversity, and soil organisms play pivotal roles in supporting terrestrial life, but the role that individual plants and plant communities play in influencing the diversity and functioning of soil food webs remains highly debated. Plants, as primary producers and providers of resources to the soil food web, are of vital importance for the composition, structure, and

Disrupting the public-private distinction: excavating the government of carbon markets post-Copenhagen

This paper draws upon the recent carbon market turmoil to understand how the private realm is imagined in global climate governance. Instead of asking which entities (eg, public or private authorities) govern the carbon economy, we draw attention to the procedures (eg, caps on emissions, techniques of verification, or performance standards) by which carbon markets are made thinkable and governable

Mechanical soil disturbance as a determinant of arbuscular mycorrhizal fungal communities in semi-natural grassland.

While the effect of disturbance on overall abundance and community composition of arbuscular mycorrhizal (AM) fungi has been researched in agricultural fields, less is known about the impact in semi-natural grasslands. We sampled two AM plant species, Festuca brevipila and Plantago lanceolata, from an ongoing grassland restoration experiment that contained replicated plowed and control plots. The

Sharing the bounty-Adjusting harvest to predator return in the Scandinavian human-wolf-bear-moose system

The increase and range extension of wolves (Canis lupus L) and brown bears ( Ursus arctos L) in Scandinavia inevitably impacts moose (Alces alces L.) populations and, as a consequence, the size and composition of the hunter harvest must be adjusted. We used a sex- and age-structured moose population model to delineate optimal harvest strategies under predation and to compare the resulting harvest

Natural Establishment of Specialist Plant Species after Topsoil Removal and Soil Perturbation in Degraded Calcareous Sandy Grassland

Specialist plant species in calcareous sandy grasslands are threatened by acidification and high nutrient levels in the topsoil. We investigated whether topsoil removal and soil perturbation in degraded sandy grasslands could lead to establishment of specialist species belonging to the threatened xeric sand calcareous grassland habitat. Restoration actions performed in 2006 resulted in increased s

Use of dynamic soil-vegetation models to assess impacts of nitrogen deposition on plant species composition: an overview

Field observations and experimental data of effects of nitrogen (N) deposition oil plant species diversity have been Used to derive empirical critical N loads for various ecosystems. The great advantage of such an approach is the inclusion of field evidence, but there are also restrictions, such as the absence of explicit criteria regarding significant effects on the vegetation, and the impossibil

Institutional Interactions at the Crossroads of Trade and Environment: the Dominance of Liberal Environmentalism?

This article argues that institutional interactions that cut across the domains of trade and environment are embedded in overarching norms that shape their evolution and impact. In making this argument, it analyzes three cases of such interactions within the climate change and biosafety regime complexes: those relating to trade-related climate policies and measures, forest carbon sinks, and trade

Induced allopatry as main mechanism explaining trap catch reduction in low dose mating disruption trials on the strawberry pest Acleris comariana (Lepidoptera: Tortricidae)

BACKGROUND: The strawberry tortrix, Acleris comariana (Lepidoptera: Tortricidae), is a destructive pest of strawberry in Denmark and southern Sweden. The efficacy of pheromone-based communication disruption of the species was examined in crop fields in southern Sweden. Due to the high cost of purchasing or synthesizing the pheromone (E)-11,13-tetradecadienal, lower quantities were applied per ha c

Geographic Distribution, Flight Phenology and Infestation Level of the Lepidopteran Pests Euhyponomeutoides albithoracellus, Lampronia capitella and Synanthedon tipuliformis on Black Currants in Northern Europe

The currant bud moth, Euhyponomeutoides albithoracellus, the currant shoot borer, Lampronia capitella and the currant clearwing, Synanthedon tipuliformis, are destructive pests on currants in the Nordic countries, but detailed information about their relative abundance in commercial crop fields is lacking. We used pheromone-baited monitoring traps to analyse the presence and flight period of the t

Whose risk counts? Climate risk frames in global green finance governance complex

In recent decades, global green finance governance institutions (GGFGIs) have developed diverse frames for understanding climate-related risks. Understanding these risk frames is crucial because they lead to distinctive “de-risking” policies, empowering different types of actors. This paper examines how GGFGIs produce different climate risk frames, and what the prevailing climate risk frame is and

Closing the Funding Gap: Biodiversity Finance Mechanisms

The Kunming-Montréal Global Biodiversity Framework, adopted at COP15, establishes a clear mandate to mobilize funding from diverse sources to address the escalating biodiversity crisis. Despite growing awareness and commitment to biodiversity conservation, a substantial financing gap persists, hindering efforts to protect and restore ecosystems effectively. This chapter provides an in-depth examin

Bee and non-bee pollinator importance for local food security

Pollinators are critical for food security; however, their contribution to the pollination of locally important crops is still unclear, especially for non-bee pollinators. We reviewed the diversity, conservation status, and role of bee and non-bee pollinators in 83 different crops described either as important for the global food market or of local importance. Bees are the most commonly recorded c

Monitoring Spatial-Temporal Variations of Lake Level in Western China Using ICESat-1 and CryoSat-2 Satellite Altimetry

The lakes in the arid or semi-arid regions of western China are more sensitive to climate changes, and lake levels are considered as a direct indicator of regional climate variability. In this study, we combined satellite altimetry data from ICESat-1 with a smaller footprint and higher accuracy (compared to radar altimetry) and CryoSat-2 with a higher resolution in the along-track direction to mon

Understanding the adaptive capacity of the bumblebee Bombus terrestris across native and novel environments

Anthropogenic stressors such as agricultural intensification, climate change, andincreased densities of non-native managed bees used for crop pollination arecontributing to bee declines. Understanding how and why bees have responded topast environmental changes is crucial for predicting future ones and enablingmitigation to maintain the functioning of both natural and agricultural ecosystems.The a

Pedon-scale silicate weathering : comparison of the PROFILE model and the depletion method at 16 forest sites in Sweden

Weathering of soil minerals is important for the recovery from acidification and for the sustainability of forestry. However, there is still substantial uncertainty about its absolute rate. This study presents a harmonized comparison of field weathering rates estimated with the mechanistic model PROFILE and the depletion method for 16 intensively sampled soil profiles across Sweden representing di
