Abstract Climate change and habitat loss present serious threats to nature. Yet, due a lack of historical land-use data, the potential for baseline conditions interact with changing climate affect biodiversity remains largely unknown. Here, we use land use, data species observation investigate patterns causes in Great Britain. We show that anthropogenic conversion have broadly led increased richness, biotic homogenization warmer-adapted communities British birds, butterflies plants over long...
Plant communities are often dispersal‐limited and zoochory can be an efficient mechanism for plants to colonize new patches of potentially suitable habitat. We predicted that seed dispersal by ungulates acts as ecological filter – which differentially affects individuals according their characteristics shapes species assemblages the varies (endozoochory, fur‐epizoochory hoof‐epizoochory). conducted two‐step individual participant data meta‐analyses 52 studies on plant in fragmented...
Summary Dispersal is essential for species to survive the threats of habitat destruction and climate change. Combining descriptions dispersal ability with those landscape structure, concept functional connectivity has been popular understanding predicting species’ spatial responses environmental Following recent advances, now able move beyond structure consider more explicitly how other external factors such as resources affect movement. We argue that these factors, in addition a...
Extensive changes in land cover during the 20th century are known to have had detrimental effects on biodiversity rural landscapes, but magnitude of change and their ecological not well regional scales. We digitized historical maps from beginning over a 1652 km(2) study area southeastern Sweden, comparing it modern-day with focus valuable habitat types. Semi-natural grassland decreased by 96 % area, being largely lost afforestation silviculture. Grasslands finer soils were more likely be...
Connectivity is key for understanding how ecological systems respond to the challenges of land-use change and habitat fragmentation. Structural functional connectivity are both established concepts in ecology, but temporal component deserves more attention. Whereas often associated with spatial patterns (spatial connectivity), relates persistence organisms time, same place. Both processes determine biodiversity responses changes landscape structure, it therefore necessary that all aspects...
Abstract Aim Climate and land use are key determinants of biodiversity, with past ongoing changes posing serious threats to global ecosystems. Unlike most other organism groups, plant species can possess dormant life‐history stages such as soil seed banks, which may help communities resist or at least postpone the detrimental impact changes. This study investigates potential for banks achieve this. Location Europe. Time period 1978–2014. Major taxa studied Flowering plants. Methods Using a...
Habitat loss through land-use change is the most pressing threat to biodiversity worldwide. European semi-natural grasslands have suffered an ongoing decline since early twentieth century, but we limited knowledge of how grassland has affected across large spatial scales. We quantify over 50-70 years a 175,000 km2 super-region in southern Sweden, identifying widespread open cover and homogenisation landscape structure, although these patterns vary considerably depending on historical...
Objective: To review the recent research into human-mediated dispersal (HMD) in European rural landscape, and explore potential positive aspect of HMD for grassland conservation, contrast to it's common association with spread invasive species. Methods: A literature search was undertaken identify vectors landscape discussion regarding past present, implications management, identification future needs. Results: Grazing animals are important propagule dispersers, but reduced movement livestock...
Summary 1. Seed bank and seed rain represent dispersal in time space. They can be important sources of diversity the rural landscape, where fragmented habitats are linked by their histories. 2. bank, above‐ground vegetation were sampled four habitat types (abandoned semi‐natural grassland (ABA), grazed former arable field (FAF), mid‐field islet (MFI) (SNG)) a landscape southern Sweden, to examine whether community patterns distinguished at large spatial scales best explained current, past or...
Abstract Dispersal is a key process in determining the survival of plant species following habitat fragmentation and climate change, as well driving introduction spread invasive alien new regions. Due to its passive nature, seed dispersal particularly complex, rare long‐distance events relevant for species' responses environmental change are barrier understanding. Attempts simplify often ignore by humans, despite huge influence humans have over ecological systems throughout world. In this...
Abstract Serious concerns exist about potentially reinforcing negative effects of climate change and land conversion on biodiversity. Here, we investigate the tandem interacting roles warming land-use as predictors shifts in regional distributions 1701 plant species Sweden over 60 years. We show that associated with warmer climates have increased, while grassland specialists declined. Our results also support hypothesis vegetation densification through grazing abandonment synergistic...
Abstract Although increased temperatures are known to reinforce the effects of habitat destruction at local landscape scales, evidence their additive or interactive is limited, particularly over larger spatial extents and longer timescales. To address these deficiencies, we created a dataset land-use changes 75 years, documenting loss half (>3000 km 2 ) semi-natural grassland Great Britain. Pairing this with climate change data, tested for relationships distribution in birds, butterflies,...
Abstract Road verges can support high densities of flowers and could therefore provide new opportunities for the conservation flower‐visiting insects. One way optimizing road vascular plant diversity is to adjust mowing regimes, but date it unclear how this affects Furthermore, mobile organisms like wild bees butterflies, there a risk that benefit increased habitat quality in limited by proximity traffic, poorly studied. In crossed study design, we separated time frequency (early summer...
Humans are known for their capacity to disperse organisms long distances. Long-distance dispersal can be important species threatened by habitat destruction, but research into human-mediated is often focused upon few and/or invasive species. Here we use citizen science identify the humans seeds on clothes and footwear from a pool in valuable habitat, allowing an assessment of fraction types dispersed alternative context. We collected material volunteers cutting 48 species-rich meadows...
Abstract The delivery of rigorous and unbiased evidence on the effects interventions lay at heart scientific method. Here we examine papers evaluating agri‐environment schemes, principal instrument to mitigate farmland biodiversity declines worldwide. Despite previous warnings about rudimentary study designs in this field, found that majority studies published between 2008 2017 still lack robust strictly evaluate intervention effects. Potential sources bias arise from correlative nature are...
Globally, rising temperatures are increasingly favoring warm-affiliated species. Although changes in community composition typically measured by the mean temperature affinity of species (the index, CTI), they may be driven different processes and accompanied shifts diversity affinities breadth thermal niches. To resolve pathways to warming Finnish flora fauna, we examined multidecadal dominance among understory forest plant, freshwater phytoplankton, butterfly, moth, bird communities. CTI...
Abstract Question To what extent does the movement of animals between fragmented habitat patches provide functional connectivity via endozoochorous seed dispersal? Location The Stockholm archipelago, Sweden. Methods We followed all movements livestock islands during one grazing season. After each movement, manure was collected and its content assessed through seedling emergence. Seedling data were then compared to vegetation surveys from grazed with regard traits. Results Light‐...
Understanding how landscape patterns affect species diversity is of great importance in the fields biogeography, ecology and conservation planning, but despite rapid advance biodiversity analysis, investigations spatial effects on are still largely focused richness. We wanted to know if richness composition differentially driven by measures dominating studies biogeography. As both require same limited presence/absence information, it important choose an appropriate measure, as differing...
Summary Immigration, extirpation and persistence of individual populations species are key processes determining community responses to environmental change. However, they difficult study over long time periods without corresponding historical modern‐day occurrences. We used present‐day plant occurrence data from two different spatial scales (resolutions) investigate the turnover during 20th century in a Baltic Sea archipelago. Patterns were analysed relation functional traits relating...
Abstract Climate change, land‐use change and introductions of non‐native species are key determinants biodiversity worldwide. However, the extent to which anthropogenic drivers environmental interact affect biological communities is largely unknown, especially over longer time periods. Here, we show that plant community composition in 996 Swedish landscapes has consistently shifted reflect warmer wetter climate region experienced during second half 20th century. Using climatic indices,...
