Soil organisms, including earthworms, are a key component of terrestrial ecosystems. However, little is known about their diversity, distribution, and the threats affecting them. We compiled global dataset sampled earthworm communities from 6928 sites in 57 countries as basis for predicting patterns abundance, biomass. found that local species richness abundance typically peaked at higher latitudes, displaying opposite to those observed aboveground organisms. high dissimilarity across...
Linking variation in species' traits to large-scale environmental gradients can lend insight into the evolutionary processes that have shaped functional diversity and future responses change. Here, we ask how heat cold tolerance vary as a function of latitude, elevation climate extremes, using an extensive global dataset ectotherm endotherm thermal limits, while accounting for methodological acclimation temperature, ramping rate duration exposure among studies. We show previously reported...
Abstract Understanding how species’ thermal limits have evolved across the tree of life is central to predicting responses climate change. Here, using experimentally-derived estimates tolerance for over 2000 terrestrial and aquatic species, we show that most variation in can be attributed a combination adaptation current climatic extremes, existence evolutionary ‘attractors’ reflect either boundaries or optima limits. Our results also reveal deep-time legacies ectotherms, whereby orders...
How climate affects species distributions is a longstanding question receiving renewed interest owing to the need predict impacts of global warming on biodiversity. Is change forcing live near their critical thermal limits? Are these limits likely through natural selection? These and other important questions can be addressed with models relating geographical data, but inferences made are highly contingent non-climatic factors such as biotic interactions. Improved understanding effects will...
A global dataset shows that animal pollinators are crucial for reproduction in half of wild flowering plants.
Abstract Land use change, by disrupting the co-evolved interactions between plants and their pollinators, could be causing plant reproduction to limited pollen supply. Using a phylogenetically controlled meta-analysis on over 2200 experimental studies more than 1200 wild plants, we ask if land intensification is at global scales. Here report that reliant pollinators in urban settings are similarly pollinator-reliant other landscapes. Plants functionally specialized bee natural managed...
There is an urgent need to synthesize the state of our knowledge on plant responses climate. The availability open-access data provide opportunities examine quantitative generalizations regarding which biomes and species are most responsive climate drivers. Here, we time series structured population models from 162 populations 62 plants, mostly herbaceous temperate biomes, link growth rates (λ) precipitation temperature We expect: (1) more pronounced demographic than temperature, especially...
Abstract Aim Biodiversity and ecosystem productivity vary across the globe, considerable effort has been made to describe their relationships. functioning research traditionally focused on how experimentally controlled species richness affects net primary ( S → NPP) at small spatial grains. In contrast, influence of (NPP ) explored many grains in naturally assembled communities. Mismatches scale between approaches have fuelled debate about strength direction biodiversity–productivity Here,...
Abstract Earthworms are an important soil taxon as ecosystem engineers, providing a variety of crucial functions and services. Little is known about their diversity distribution at large spatial scales, despite the availability considerable amounts local-scale data. Earthworm data, obtained from primary literature or provided directly by authors, were collated with information on site locations, including coordinates, habitat cover, properties. Datasets required, minimum, to include...
Abstract Plant reproduction relies on transfer of pollen from anthers to stigmas, and the majority flowering plants depend biotic or abiotic agents for this transfer. A key metric characterizing if receipt is insufficient limitation, which assessed by supplementation experiments. In a experiment, fruit seed production flowers exposed natural pollination compared that following hand either (i.e. manual outcross addition without bagging) outcrossing bagged flowers, excludes pollination. The...
Abstract Understanding how temperature determines the distribution of life is necessary to assess species’ sensitivities contemporary climate change. Here, we test importance in limiting geographic ranges ectotherms by comparing temperatures and areas that species occupy could potentially on basis their physiological thermal tolerances. We find marine across all latitudes terrestrial from tropics closely match However, temperate polar are absent warm, thermally tolerable they beyond...
ABSTRACT Motivation Pollinators play a crucial role in maintaining Earth's terrestrial biodiversity. However, rapid human‐induced environmental changes are compromising the long‐term persistence of plant‐pollinator interactions. Unfortunately, we lack robust, generalisable data capturing how communities structured across space and time. Here, present EuPPollNet (European Plant‐Pollinator Networks) database, fully open European‐level database containing harmonised taxonomic on interactions...
Abstract Aim Climate change is expected to increase the frequency and intensity of extreme climatic events, such as severe droughts intense rainfall periods. We explored how avifauna a highly modified region responded 13‐year drought (the ‘Big Dry’), followed by two‐year period substantially higher than average Wet’). Location Temperate woodlands in north central Victoria, Australia. Methods used two spatially extensive, long‐term survey programmes, each which was repeated three times: early...
Abstract Species interactions are known to be key in driving patterns of biodiversity across the globe. Plant-plant through heterospecific pollen (HP) transfer by their shared pollinators is common and has consequences for plant reproductive success floral evolution, thus potential influence global community assembly. The literature on HP growing it therefore timely review causes among-species variation receipt at a scale, uncovering its contribution biodiversity. Here we analyzed published...
Abstract Aim Climate change has been linked to negative effects on vegetation, including drought‐induced dieback. Large‐scale dieback not only leads considerable carbon emissions but often loss of ecological resources. We investigated whether, and how, the structure, composition content changed over a period extended drought (the ‘ B ig D ry’) in much‐modified forest ecosystem. explored whether landscape configuration, management practice or soil type influenced vegetation change. Location...
Climate change may amplify the adverse effects of fragmentation by also affecting interspecific interactions. Increased competition reduce ability already stressed species to acquire resources (breeding sites and food), reducing recruitment long‐term viability species. We assessed how measures native birds were influenced area vegetation, vegetation characteristics, as an indication degradation, occurrence increasingly prevalent competitor (the noisy miner Manorina melanocephala ). recorded...
Adaptive resource tracking in space and time may be disrupted by the modification of resources competitors. Major global change drivers (e.g. land-use change) have induced declines many native species, while facilitating only a few. Given that are predicted to become increasingly scarce under joint effects climate change, disturbance-tolerant species able defend high-value further limit persistence disturbance-sensitive species. We sought determine which nectarivorous birds track variation...
How will anthropogenic changes (species invasions/extinctions, land-use conversion, and climate change) influence the pollination reproductive success of world's angiosperms, 85% which require animal (Ollerton et al., 2011)? Answering this question requires understanding mechanisms that cause pollen limitation seed production. Pollen (PL) is widespread (Bennett 2018) occurs when pollinators fail to deliver adequate quantity or quality stigmas (Ashman 2004). It thought primarily occur there...
