Species distributions and abundances are undergoing rapid changes worldwide. This highlights the significance of reliable, integrated information for guiding assessing actions policies aimed at managing sustaining many functions benefits species. Here we synthesize types data approaches that required to achieve such an integration conceptualize 'essential biodiversity variables' (EBVs) a unified global capture species populations in space time. The inherent heterogeneity sparseness raw...
Abstract Concern about biodiversity loss has led to increased public investment in conservation. Whereas there is a widespread perception that such initiatives have been unsuccessful, are few quantitative tests of this perception. Here, we evaluate whether rates change altered recent decades three European countries (Great Britain, Netherlands and Belgium) for plants flower visiting insects. We compared four 20‐year periods, comparing periods rapid land‐use intensification natural habitat...
1 The objective of this study was to test the theoretical prediction that thermal tolerance range for development in insects should be about 20 °C. 2 data on requirements 66 species from eight orders obtained literature. temperatures at which developmental rates are their minimum and maximum each population by defining relationship between rate (1/D) temperature, using either Lactin et al.'s (1995) or Briére (1999) model. 3 Thermal windows, i.e. temperature individual species, temperatures,...
Abstract Aim We test the prediction that beta diversity (species turnover) and decay of community similarity with distance depend on spatial resolution (grain). also study whether patterns are related to variability in climate, land cover or geographic how independent effects these variables grain data. Location Europe, Great Britain, Finland Catalonia. Methods used data European birds, plants, butterflies, amphibians reptiles, British Catalonian birds Finnish butterflies. fitted two three...
Abstract Predictions of how different facets biodiversity decline with habitat loss are broadly needed, yet challenging. Here we provide theory and a global empirical evaluation to address this challenge. We show that extinction estimates based on endemics–area backward species–area relationships complementary, the crucial difference comprises geometry area loss. Across three taxa four continents, relative species, phylogenetic functional diversity, is highest when habitable disappears...
Abstract How biodiversity underpins ecosystem resistance (i.e. ability to withstand environmental perturbations) and recovery return a pre‐perturbation state), thus, stability under extreme climatic events is timely question in ecology. To date, most studies have focussed on the role of taxonomic diversity, neglecting how community functional composition diversity beget exceptional conditions. In addition, land use potentially modulates functions respond Using an 11‐year time‐series plant...
Summary Reliable methods to downscale species distributions from coarse fine grain (equivalent resolution or support) hold great potential benefit for ecology and conservation. Existing have been based on partially unrealistic assumptions yield mixed results. Here, we introduce a novel simple approach downscaling distribution models hierarchical B ayesian modelling ( HBM ) framework. Our treats putative (unknown) fine‐grain presences/absences as latent variables, which are modelled function...
Mapping malaria risk is an integral component of efficient resource allocation. Routine health facility data are convenient to collect, but without information on the locations at which transmission occurred, their utility for predicting variation in a sub-catchment level presently unclear. Using routinely collected case Swaziland between 2011–2013, and fine scale environmental ecological variables, this study explores use hierarchical Bayesian modelling framework downscaling maps from...
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 Community ecologists and macroecologists have long sought to evaluate the importance of environmental conditions in determining species distributions, community composition, diversity across sites. Different methods been used estimate species–environment relationships, but their differences jointly fit disentangle spatial autocorrelation structure remain poorly studied. We compared how four broad families statistical models estimated contribution environment space variation...
Variables describing the abiotic environment (e.g. climate, topography or biogeographic history) have a long tradition of use as predictors tree species richness patterns. However, these variables may capture variations in related to but not those that are soil type forest disturbance. Canopy structure has previously been shown provide information on variation richness, with generally increasing larger canopy heights and denser foliage. The is increasingly relevant availability such data...
Abstract Aim Despite the complexity of population dynamics, most studies concerning current changes in bird populations reduce trajectory change to a linear trend. This may hide more complex patterns reflecting responses changing anthropogenic pressures. Here, we address this by means multivariate analysis and attribute different components dynamics potential drivers. Location Czech Republic. Methods We used data on trajectories (1982–2019) 111 common breeding species, decomposed them into...
Aim To evaluate the strength of evidence for hypotheses explaining relationship between climate and species richness in forest plots. We focused on effect energy availability which has been hypothesized to influence richness: (1) via productivity total number individuals (the more hypothesis, MIH); (2) through temperature metabolic rate (metabolic theory biodiversity, MTB); or (3) by imposing climatic limits distributions. Location Global. Methods utilized a unique ‘Gentry-style’ 370 plots...
Spatial variation in biodiversity is the result of complex interactions between evolutionary history and ecological factors. Methods historical biogeography combine phylogenetic information with current species locations to infer a clade through space time. A major limitation most methods for biogeographic inference requirement single terminal lineages, reducing contemporary geographical ranges point two-dimensional space. In reality, geographic usually show patterns, irregular shapes, or...
Abstract Aim A fundamental question in macroecology centres around understanding the relationship between species’ local abundance and their distribution geographical climatic space (i.e. multi‐dimensional or niche). Here, we tested three macroecological hypotheses that link to following range properties: (a) abundance–range size relationship, (b) centre (c) abundance–suitability relationship. Location Europe. Taxon Vascular plants. Methods Distribution maps were extracted from Chorological...
Abstract Interspecific spatial associations (ISA), which include co‐occurrences, segregations, or attractions among two more species, can provide important insights into the structuring of communities. However, ISA has primarily been examined in context understanding interspecific interactions, while other aspects ISA, including its relations to biodiversity facets and how it changes face anthropogenic pressures, have largely neglected. This is likely because unclear what makes useful a...
Abstract Species distribution models (SDMs) are algorithms designed to infer the of species using environmental and biotic variables have become an important tool for ecologists conservation biologists seeking understand implications change. Global datasets at resolutions a few metres increasingly available. SDMs fitted such high‐resolution data allow researchers investigate how local factors affect occurrences unprecedented fine spatial scales. As resolution increases, we see critical need...
