It is often claimed that we do not understand the forces driving global diversity gradient. However, an extensive literature suggests contemporary climate constrains terrestrial taxonomic richness over broad geographic extents. Here, review empirical to examine nature and form of relationship between richness. Our goals were document support for climatically based energy hypothesis, within constraints imposed by correlative analyses, evaluate two versions hypothesis: productivity ambient...
Abstract Broad‐scale variation in taxonomic richness is strongly correlated with climate. Many mechanisms have been hypothesized to explain these patterns; however, testable predictions that would distinguish among them rarely derived. Here, we examine several prominent hypotheses for climate–richness relationships, deriving and testing based on their mechanisms. The ‘energy–richness hypothesis’ (also called the ‘more individuals hypothesis’) postulates more productive areas therefore...
Abstract Aim We surveyed the empirical literature to determine how well six diversity hypotheses account for spatial patterns in species richness across varying scales of grain and extent. Location Worldwide. Methods identified 393 analyses (‘cases’) 297 publications meeting our criteria. These criteria included requirement that more than one hypothesis was tested its relationship with richness. grouped variables representing into following ‘correlate types’: climate/productivity,...
Abstract Although satellite‐based variables have for long been expected to be key components a unified and global biodiversity monitoring strategy, definitive agreed list of these still remains elusive. The growth interest in observable from space has partly underpinned by the development essential variable ( EBV ) framework Group on Earth Observations – Biodiversity Observation Network, which itself was guided process identifying climate variables. This contribution aims advance strategy...
A major focus of geographical ecology and macroecology is to understand the causes spatially structured ecological patterns. However, achieving this understanding can be complicated when using multiple regression, because relative importance explanatory variables, as measured by regression coefficients, shift depending on whether explicit or non‐spatial modeling used. extent which coefficients may why shifts occur are unclear. Here, we analyze relationship between environmental predictors...
Abstract Societal, economic and scientific interests in knowing where biodiversity is, how it is faring what can be done to efficiently mitigate further loss the associated of ecosystem services are at an all‐time high. So far, however, monitoring has primarily focused on structural compositional features ecosystems despite growing evidence that functions key elucidating mechanisms through which biological diversity generates humanity. This gap traced current lack consensus exactly track...
While greater research on threatened species alone cannot ensure their protection, understanding taxonomic bias may be helpful to address knowledge gaps in order identify directions and inform policy. Using data for over 10 000 animal listed the International Union Conservation of Nature Red List, we investigated geographic biodiversity conservation trends worldwide. We found extreme effort vertebrates compared with lesser-studied invertebrates both terrestrial aquatic habitats at a global...
Although large reserve networks will be integral components in successful biodiversity conservation, implementation of such systems is hindered by the confusion over relative importance endemism and species richness. There evidence ( Prendergast et al. 1993) that regions with high richness for a taxon tend to different from those endemism. I tested this finding using distribution data 368 Mammalia, Lasioglossum, Plusiinae, Papilionidae. The study area, subdivided into 336 quadrats, was...
Although there is no shortage of potential explanations for the large-scale patterns biological diversity, hypothesis that energy-related factors are primary determinants perhaps most extensively supported, especially in cold-temperate regions. By using unusually high-resolution biodiversity and environmental data have not previously been available, we demonstrate habitat heterogeneity, as measured by remotely sensed land cover variation, explains Canadian butterfly richness better than any...
Both natural and anthropogenic factors are important in determining a species’ risk of extinction. Little work has been done, however, to quantify the magnitude current influences on extinction process. The purpose this study is determine extent which measures intensity human activity related global variability two susceptibility We observed six indices activities 90 countries, we tested their relationships proportion threatened bird mammal species each country, as well mammalian population...
Accurate predictions of future shifts in species diversity response to global change are critical if useful conservation strategies be developed. The most widely used prediction method is model individual niches from point observations and project these models forward using climate scenarios. resulting changes ranges then summed predict changes; multiple can combined produce ensemble forecasts. Predictions based on environment‐richness regressions rarer. However, richness regression models,...
Abstract Canada is one of the last places on earth with extensive wilderness areas, yet number Canadian species threatened extinction continues to rise every year. Using satellite‐derived land use data, we find that habitat loss explains most variation in numbers endangered across Canada. Habitat within ranges is, therefore, likely be leading factor inhibiting their recovery. We measured individually known 243 terrestrial at risk Recovery potential, as by extent natural each species’ range,...
We compiled 46 broadscale data sets of species richness for a wide range terrestrial plant, invertebrate, and ectothermic vertebrate groups in all parts the world to test ability metabolic theory account observed diversity gradients. The makes two related predictions: (1) ln-transformed is linearly associated with linear, inverse transformation annual temperature, (2) slope relationship near −0.65. Of sets, 14 had no significant relationship; remaining 32, nine were meeting prediction 1....
Global changes have the potential to cause a mass extinction. Predicting how species will respond anticipated is necessary prerequisite effectively conserving them and reducing extinction rates. Species niche models are widely used for such predictions, but their reliability over long time periods known vary. However, climate land use in northern countries provide pseudo-experiment test model predicting future conditions, provided historical data on both distributions environmental...

To prioritize areas for conservation, biologists and managers need information on species diversity in threatened habitats. The resources available such inventories remain severely limited, increasing the to develop speedier ways estimate status of target We present a study use techniques highly fragmented oak savannas southern Ontario, including selection indicator taxa, rapid biodiversity assessment based morphospecies, analysis community structure. found that butterflies skippers can be...
Few studies have addressed patterns and causes of species endangerment at different resolutions geographical extents. Using newly developed remote sensing distribution data sets, we examined the influence both natural anthropogenic factors on density terrestrial endangered in Canada two spatial scales. The first was a national extent second within region (the mixed wood plains) where there are particularly large numbers species. We also protected areas throughout to determine their capacity...
Global climate change is a major threat to biodiversity. The most common methods for predicting the response of biodiversity changing do not explicitly incorporate fundamental evolutionary and ecological processes that determine species responses climate, such as reproduction, dispersal, adaptation. We provide an overview emerging mechanistic spatial theory range shifts under change. This theoretical framework defines contribute via biologically meaningful reproductive, envelope parameters....
Abstract Several North American bumblebee species have recently undergone dramatic declines. The use of managed, pathogen‐carrying bumblebees for pollination greenhouse crops began shortly before these declines, and wild near greenhouses now high pathogen loads. This has led to speculation that spillover from commercial caused declines species. We test this hypothesis using a large dataset occurrence records agricultural census data. find support the two but no evidence disappearance...
