Widely used European land cover maps such as CORINE are produced at medium spatial resolutions (100 m) and rely on diverse data with complex workflows requiring significant institutional capacity. We present a high resolution (10 map (ELC10) of Europe based satellite-driven machine learning workflow that is annually updatable. A Random Forest classification model was trained 70K ground-truth points from the LUCAS (Land Use/Cover Area frame Survey) dataset. Within Google Earth Engine cloud...
A recurrent concern in nature conservation is the potential competition for forage plants between wild bees and managed honey bees. Specifically, that highly sophisticated system of recruitment large perennial colonies quickly exhaust resources leading to local extirpation However, different species show preferences plants. We here summarize known bee at national scale Denmark. Our focus on floral shared by bees, with an emphasis both threatened foraging specialist species. Across all 292...
ABSTRACT Aim The functional diversity of bees contribute to the maintenance plant biodiversity because different species wild prefer and pollinate plants. Many bees, in particular with narrow flower preferences or specialised habitat requirements, are threatened by landscape homogenisation climate change. Nonetheless, we still lack an understanding large‐scale impacts anthropogenic stressors on distribution bee preferences. Location Northern Europe: Norway, Denmark Germany. Methods We...
A central goal in ecology is to develop theories that explain the diversity and distribution of species. The evolutionary history species their functional traits may provide mechanistic links between community assembly environment. Such be hierarchically structured such strength environmental filtering decreases a step‐wise manner from regional conditions through landscape heterogeneity local habitat conditions. We sampled wild bee assemblages power‐line strips transecting forests...
Anthropogenic landscape elements, such as roadsides, hedgerows, field edges, and power line clearings, can be managed to provide important habitats for wild bees. However, the effects of habitat improvement schemes in clearings on components diversity are poorly studied. We conducted a large-scale experiment test different management practices species, phylogenetic, functional bees (n = 19 sites across southeastern Norway) explored whether any treatment were modified by environmental...
Abstract Sowing flower strips along field edges is a widely adopted method for conserving pollinating insects in agricultural landscapes. To maximize the effect of given limited resources, we need spatially explicit tools that can prioritize their placement, and identifying plant species to include seed mixtures. We sampled bees as well interactions semi‐controlled experiment with roadside/field edge pairs with/without sown strip at 31 sites Norway used regional spatial model solitary bee...
Declining populations of wild pollinators have increased the interest in management human-modified landscapes for pollinator conservation. Modified landscape features, such as power-line clearings, may provide valuable habitats with floral resources insect and solitary bees particular. However, whether effects costly habitat interventions on bee communities clearings are sustained over time, is poorly understood. We conducted an experiment 19 sites across southeast Norway where woody...
Abstract The species composition within communities is highly dependent on the rate of immigration and whether immigrating possess functional traits required by prevailing environmental conditions. Once established, random fluctuations in birth death rates may reduce diversity ecologically equivalent if local populations are not replenished individuals. Consequently, three key processes drive community assembly: dispersal limitation, ecological filtering, drift. However, disentangling...
Inter-specific interactions are important drivers and maintainers of biodiversity. Compared to trophic competitive interactions, the role non-trophic facilitation among species has received less attention. Cavity-nesting bees nest in old beetle borings dead wood, with restricted diameters corresponding body size bee species. The aim this study was test hypothesis that functional diversity cavity-producing wood boring beetles - terms cavity drives cavity-nesting bees. invertebrate communities...
Abstract To mitigate biodiversity loss, it is essential to understand how areas altered by human land use can act as alternative habitats for functional groups of species, which are in decline. In forested landscapes, power‐line clearings be valuable early successional plant turn provide important food resources pollinating insects. However, we know little about management practices affect diversity, or changes species diversity translate into the floral resources. We conducted an experiment...
Entomological sampling and storage conditions often prioritise efficiency, practicality conservation of morphological characteristics, may therefore be suboptimal for DNA preservation. This practice can impact downstream molecular applications, such as the generation high-throughput genomic libraries, which requires substantial input amounts. Here, we use a practical Tn5 transposase tagmentation-based library preparation method optimised 96-well plates low yield extracts from insect legs...
Climate change, landscape homogenization, and the decline of beneficial insects threaten pollination services to wild plants crops. Understanding how potential (i.e. capacity ecosystems support plants) is affected by climate change homogenization fundamental for our ability predict such anthropogenic stressors affect plant biodiversity. Models pollinator are improved when based on pairwise plant–pollinator interactions pollinator's preferences. However, whether sum predicted with a within...
Mapping the spatial and temporal dynamics of species distributions is necessary for biodiversity conservation land-use planning decisions. Recent advances in remote sensing machine learning have allowed high-resolution distribution modeling that can inform landscape-level decision-making. Here we compare performance three popular Sentinel-2 (10-m) land cover maps, including dynamic world (DW), European (ELC10), (WC), predicting wild bee richness over southern Norway. The proportion grassland...
Abstract Predicting plant–pollinator interaction networks over space and time will improve our understanding of how environmental change is likely to impact the functioning ecosystems. Here we propose a framework for producing spatially explicit predictions occurrence number pairwise interactions species richness, diversity abundance pollinators visiting flowers. We call ‘MetaComNet’ because it aims link metacommunity dynamics assembly ecological networks. To illustrate MetaComNet...
Wild bees are key ecosystem components making their decline a cause for concern. An effective measure to increase wild bee diversity is enhance plant diversity. However, the effect on of augmenting depends site-specific environmental conditions. We aimed make spatial predictions where: (a) conditions maximize diversity, so that such areas can be prioritized diversity; and (b) populations threatened species most likely occur. surveyed communities in traditionally managed hay meadows SE Norway...
Conserving semi-natural grasslands, a threatened habitat type in European landscapes, is increasingly recognized as measure to conserve pollinators. Our aim was test if (a) prediction maps of solitary bee species richness could be used rank grasslands terms their potential for supporting wild bees, and (b) such predictions extend current assessment criteria that determine which are eligible being listed under conservation schemes. We sampled communities 52 southeast Norway. conducted an...
There is a global concern over insect declines, including both species loss and population declines. In particular, declines of species, such as bees that anchor trophic interactions shoulder many the essential ecosystem services, have been focus broad public concern. However, our understanding what characterizes those are lost because long periods limited by scarcity comparative studies. We here compare composition from collection sampled two decades (2000-2019) island Lolland in Denmark,...
Abstract Aim Because the ecological similarity between species is expected to increase with relatedness and that speciation a local process, phylogeny may provide common measure for influence of biogeographic processes on community assembly. We tested if similarities in floral visitation patterns within communities phylogenetic beta‐diversity among were related position bees bee phylogeny. Location Global. Methods combined genus level within‐genera phylogenies occurring 18 globally...
Prioritizing where to implement management interventions is critical because managers have limited budgets and the effect of habitat enhancement depends on site-specific environmental conditions. Field experiments can identify conditions most effective, but are typically extent thus not sufficient for producing spatial predictions that guide efforts. We tested if we could produce maps – showing enhance bee would be successful by combining plant community composition (i.e., conditions)...
Abstract Bumble bees fill an important function in temperate, boreal and alpine ecosystems as pollinators of wild plants cultivated crops. Global declines population size many bumble bee species call for knowledge about how habitats influenced by human land use can be managed to accommodate diverse communities. We carried out a field experiment study effects on communities power‐line clearings response different vegetation clearing practices: (i) cutting, (ii) cutting removing, (iii) not the...
Understanding how niche‐based and neutral processes contribute to the spatial variation in plant–pollinator interactions is central designing effective pollination conservation schemes. Such schemes are needed reverse declines of wild bees other pollinating insects, promote services cultivated plants. We used data on bee with plants belonging four tribes Loteae, Trifolieae, Anthemideae either spring‐ or summer‐flowering Cichorieae, sampled systematically along a 682 km latitudinal gradient...
