The main drivers of global environmental change (CO2 enrichment, nitrogen deposition, climate, biotic invasions and land use) cause extinctions alter species distributions, recent evidence shows that they exert pervasive impacts on various antagonistic mutualistic interactions among species. In this review, we synthesize data from 688 published studies to show these often competitive plants animals, multitrophic effects the decomposer food web, increase intensity pathogen infection, weaken...
Abstract: We synthesized key findings from the Biological Dynamics of Forest Fragments Project, world's largest and longest‐running experimental study habitat fragmentation. Although initially designed to assess influence fragment area on Amazonian biotas, project has yielded insights that go far beyond original scope study. Results suggest edge effects play a role in dynamics, matrix major connectivity functioning, many species avoid even small (<100‐m–wide) clearings. The fragmentation...
Assessing Creepy Crawlies Arthropods are the most diverse group of terrestrial animal species, yet estimates total number arthropod species have varied widely, especially for tropical forests. Basset et al. (p. 1481 , see cover) now provide more reliable richness in a rainforest Panama. Intensive sampling half hectare forest yielded just over 6000 species. Scaling up this result to whole suggests that diversity lies between 17,000 and 40,000
ABSTRACT Edge structure is one of the principal determinants extent and magnitude edge effects in forest fragments. In central Amazonia, natural succession at edges typically produces a dense wall vegetation dominated by Cecropia spp. that buffers interior. Fire encroachment into edges, however, eliminates soil seed bank, enhances plant mortality, promotes to an open, Vismia–dominated does not buffer Contrasting fire–encroached closed, non–fire–encroached were examined Amazonia assess on...
The effects of forest fragmentation on beetle species composition were investigated in an experimentally fragmented tropical landscape Central Amazonia. Leaf-litter beetles sampled at seven distances from the edge (0–420 m) along edge-to-interior transects two 100-ha fragments and continuous edges, identical series deep transects. Additional samples taken centers 10-ha 1-ha fragments. This sampling regime allowed discrimination between fragment area effects. Beetle changed significantly...
Abstract Many insect species are under threat from the anthropogenic drivers of global change. There have been numerous well‐documented examples population declines and extinctions in scientific literature, but recent weaker studies making extreme claims a crisis drawn widespread media coverage brought unprecedented public attention. This spotlight might be double‐edged sword if veracity alarmist decline statements do not stand up to close scrutiny. We identify seven key challenges drawing...
The conceptual foundations of habitat fragmentation research have not kept pace with empirical advances in our understanding species responses to landscape change, nor theoretical the wider disciplines ecology. There is now real debate whether explicit recognition ‘habitat fragmentation’ as an over‐arching domain will stimulate or hinder further progress toward and mitigating effects change. In this paper, we critically challenge discipline, attempt derive integrated perspective on best way...
Beta diversity is an important concept used to describe turnover in species composition across a wide range of spatial and temporal scales, it underpins much conservation theory practice. Although substantial progress has been made the mathematical terminological treatment different measures beta diversity, there little conceptual synthesis potential scale dependence with increasing grain geographic extent sampling. Here, we evaluate approaches scaling interpreted from 'fixed' 'varying'...
Quantifying the spatio-temporal distribution of arthropods in tropical rainforests represents a first step towards scrutinizing global biodiversity on Earth. To date most studies have focused narrow taxonomic groups or lack design that allows partitioning components diversity. Here, we consider an exceptionally large dataset (113,952 individuals representing 5,858 species), obtained from San Lorenzo forest Panama, where phylogenetic breadth arthropod taxa was surveyed using 14 protocols...
ABSTRACT Motivation The accelerated and widespread conversion of once continuous ecosystems into fragmented landscapes has driven ecological research to understand the response biodiversity local (fragment size) landscape (forest cover fragmentation) changes. This information important theoretical applied implications, but is still far from complete. We compiled most comprehensive updated database investigate how these changes determine species composition, abundance trait diversity multiple...
The availability of nonhost resource subsidies affects the ability parasitoids to overcome egg and time limitation maximize lifetime reproductive success. We combined field laboratory experiments examine effects floral on fitness aphid parasitoids. Under controlled conditions, sugar resources significantly increased longevity potential fecundity (egg load) in endoparasitoids Aphidius rhopalosiphi Diaeretiella rapae (Hymenoptera: Aphidiidae). Laboratory microcosm showed that translated into...
Both area and edge effects have a strong influence on ecological processes in fragmented landscapes, but there is little understanding of how these two factors might interact to exacerbate local species declines. To test for synergistic interactions between effects, we sampled diverse beetle community heavily landscape New Zealand. More than 35 000 beetles 900 were over large gradients habitat (10−2–106 ha) distance from patch (20–210 m the forest into both adjacent matrix). Using new...
Abstract: Habitat fragmentation causes extinction of local animal populations by decreasing the amount viable “core” habitat area and increasing edge effects. It is widely accepted that larger fragments make better nature reserves because core‐dwelling species have a suitable habitat. Nevertheless, in real landscapes complex, irregular shapes. We modeled population sizes representative range preferences for or aversions to edges at five spatial scales (within 10, 32, 100, 320, 1000 m an...
