study of the issue indicates that it is not a serious problem for neutral theory, reasons we discuss below. First, bit background. Hubbell (2001) derived analytical expression stochastic mean and variance abundance single arbitrary species in community undergoing immigration from metacommunity source area. However, his approach did lend itself to an solution distribution relative (RSA) multispecies sizes larger than handful individuals. As result, all Hubbell's RSA distributions local...
New roads, agricultural projects, logging, and mining are claiming an ever greater area of once-pristine Amazonian forest. The Millennium Ecosystems Assessment (MA) forecasts the extinction a large fraction tree species based on projected loss forest cover over next several decades. How accurate these estimates rates? We use neutral theory to estimate number, relative abundance, range size in Amazon metacommunity likely tree-species extinctions under published optimistic nonoptimistic...

Islands harbour evolutionary and ecologically unique biota, which are currently disproportionately threatened by a multitude of anthropogenic factors, including habitat loss, invasive species climate change. Native forests on oceanic islands important refugia for endemic species, many rare highly threatened. Long-term monitoring schemes those biota ecosystems urgently needed: (i) to provide quantitative baselines detecting changes within island ecosystems, (ii) evaluate the effectiveness...
Abstract Aim Land‐use change is a major threat to biodiversity globally. Roads cause direct mortality and limitation of individual movements, which may isolate populations affect their viability in the long term. Here we provide first comprehensive global assessment exposure terrestrial mammalian carnivores roads using an integrated modelling framework. Location Global. Methods We estimated critical road densities patch sizes for each species based on spatially explicit model life‐history...
Abstract Aim The road network is increasing globally but the consequences of roadkill on viability wildlife populations are largely unknown. We provide a framework that allows us to estimate how risk extinction local increases due and generate global assessment identifies which mammalian species most vulnerable areas where they occur. Location Global. Time period 1995–2015. Major taxa studied Terrestrial mammals. Methods introduce quantify effect terrestrial mammals worldwide includes three...
Whether most species are rare or have some intermediate abundance is a long-standing question in ecology. Here, we use more than one billion observations from the Global Biodiversity Information Facility to assess global distributions (gSADs) of 39 taxonomic classes eukaryotic organisms 1900 2019. We show that, as sampling effort increases through time, shape gSAD unveiled; that is, sampled changes, revealing underlying gSAD. The fraction unveiled for each class decreases with total number...
Numerous evolutionary studies have sought to explain the distribution of diversity across limbs tree life. At same time, ecological differences in and relative abundance within among communities. Traditionally, these patterns been considered separately, but models that consider processes operating at level individuals, such as neutral biodiversity theory (NBT), can provide a link between them. Here, we compare dynamics suite NBT models. We show yield phylogenetic topologies with imbalance...
Linear infrastructures (e.g. roads, railways or power lines) promote a myriad of negative impacts on wildlife around the world, which direct mortality is most visible one. When high rates are found, mitigation measures often discussed and applied. On other hand, lack commonly interpreted as evidence low impact wildlife. We argue that may actually mask two pervasive effects linear animal populations: past massive mortality, causing local extinctions, strong barrier due to inability reluctance...
Linear infrastructures, one of several forms land-use, are a major driver biodiversity loss. Roads impact populations at many levels, with direct road mortality and barrier effect contributing to decreased population abundance, higher isolation subdivision, therefore increased extinction risk. In this paper, we compared the on isolation, persistence size, assessed interaction these effects dispersal. We used spatially explicit, process-based model dynamics in landscapes fragmented by varying...
Abstract Functional Ecology conducted a randomised trial comparing single‐ and double‐blind peer review; recent analysis of this data found substantial evidence for bias by reviewers. We show that dataset can also be analysed editor bias, after controlling both reviewer paper quality. Our shows editors tend to more likely invite high‐scoring manuscripts revision or resubmission when the first author is man from country with very high Human Development Index (HDI); authors who were women not...
Although fractals have been applied in ecology for some time, multifractals have, contrast, received little attention. In this article, we apply to the species-area relationship and species abundance distributions. We highlight two results: first, distributions collected at different spatial scales may collapse into a single curve after appropriate renormalization, second, power-law form of Shannon, Simpson, Berger-Parker diversity indices belong family equations relating number, abundance,...
Species abundance distributions are an essential tool in describing the biodiversity of ecological communities. We now know that their shape changes as a function size area sampled. Here we analyze scaling properties species by using moments logarithmically transformed number individuals. find well fitted power laws and use this pattern to estimate distribution for areas larger than those To reconstruct from its moments, discrete Tchebichef polynomials. exemplify method with data on tree...
Understanding patterns of community structure and the causes for their variation can be furthered by comparative biogeographic analyses island biotas. We used woody plant data at local scale to investigate variations in species rarity, alpha, beta, gamma diversity within between three islands from oceanic archipelagoes Azores, Canaries Mascarene. standardized protocols sample ten 50 m × forest plots each with contrasting climate regional pools: Terceira (Azores), Tenerife (Canaries), Reunion...
Summary Dispersal ecology is a topical discipline that involves understanding and predicting plant community responses to multiple drivers of global change. Propagule movements entail long‐distance dispersal ( LDD ) events are crucial for plants reach colonize suitable sites across fragmented landscapes. Yet, extremely rare, thus, obtaining reliable estimates the maximum distances propagules move their frequency has been long‐lasting challenge in ecology. Recent advances have provided...
Dispersal of organisms is a ubiquitous aspect the natural world, with wide implications across scales and organization levels. Interest in dispersal has risen sharply over past 30 years, mostly due to multiple rapid global changes ecosystems face. Among various aspects that may characterize dispersion event, distance considered key descriptor variety studies taxonomic groups. Typically, distances are defined form kernels describing distribution according probability density functions....
ABSTRACT Aim Predicting the effects of climate change on species distributions, while considering their genetic differentiation and evolutionary history is crucial to develop conservation measures. Here we aim to: assess phylogenetic phylogeographical relationships between European Neomys respective lineages; infer demographic all lineages estimate potential impact future distribution persistence lineages.
