Functional diversity is increasingly identified as an important driver of ecosystem functioning. Various indices have been proposed to measure the functional a community, but there still no consensus on which are most suitable. Indeed, none existing meets all criteria required for general use. The main that they must be designed deal with several traits, take into account abundances, and facets diversity. Here we propose three quantify each facet community species distributed in...
Functional diversity is hypothesised as being beneficial for ecosystem functions, such productivity and resistance to invasion. However, a precise definition of functional diversity, hence framework its quantification, have proved elusive. We present based on the analogy components species – richness, evenness divergence. These concepts are applied characters give three demonstrate how each these may be calculated. It hoped that our will aid in elucidation mechanisms behind...
Summary 1. Indices quantifying the functional aspect of biodiversity are essential in understanding relationships between biodiversity, ecosystem functioning and environmental constraints. Many indices diversity have been published but we lack consensus about what quantify, how redundant they which ones recommended. 2. This study aims to build a typology from artificial data sets encompassing various community structures (different assembly rules, species richness levels) identify set...
ABSTRACT Aim A large body of knowledge exists on individual anthropogenic threats that have an impact marine biodiversity in the Mediterranean Sea, although we know little about how these accumulate and interact to affect species ecosystems. In this context, aimed identify main areas where interaction between is more pronounced assess their spatial overlap with current protected Mediterranean. Location Sea. Methods We first identified high mammals, turtles, seabirds, fishes commercial or...
Human activities have strong impacts on ecosystem functioning through their effect abiotic factors and biodiversity. There is also growing evidence that species functional traits link changes in composition shifts processes. Hence, it appears to be of utmost importance quantify modifications the structure communities after human disturbance addition taxonomic structure. Despite this fact, there still little consensus actual human‐mediated habitat alteration components biodiversity, which...
Significance Our results indicate that, even in highly diverse systems like coral reefs, we can no longer assume that the erosion of species diversity be discounted by high probability functional redundancy: i.e., several support same function. Indeed, show fish tend to disproportionately pack into a few particular functions while leaving many vulnerable, they are supported just one species. Even Coral Triangle, which has concentration tropical-reef fishes, may experience loss following...
1. Understanding the structure of ecological networks is a crucial task for interpreting community and ecosystem responses to global change. 2. Despite recent interest in this subject, almost all studies have focused exclusively on one specific network property. The question remains as what extent different properties are related how understanding relationship can advance our comprehension mechanisms behind these patterns. 3. Here, we analysed between nestedness modularity, two frequently...
Abstract In a context of global changes, and amidst the perpetual modification community structure undergone by most natural ecosystems, it is more important than ever to understand how species interactions vary through space time. The integration biogeography network theory will yield results further our understanding interactions. It has, however, been hampered so far difficulty quantify variation among interaction networks. Here, we propose general framework study dissimilarity networks...
Environmental DNA reveals unsuspected shark diversity and calls for monitoring protection of residual populations.
Ecology Letters (2011) 14: 1010–1016 MacArthur and Wilson's Theory of Island Biogeography (TIB) is among the most well-known process-based explanations for distribution species richness. It helps understand species–area relationship, a fundamental pattern in ecology an essential tool conservation. The classic TIB does not, however, account complex structure ecological systems. We extend to take into trophic interactions derive species-specific model occurrence probability. find that...
Coral reefs provide ecosystem goods and services for millions of people in the tropics, but reef conditions are declining worldwide. Effective solutions to crisis facing coral depend part on understanding context under which different types conservation benefits can be maximized. Our global analysis nearly 1,800 tropical reveals how intensity human impacts surrounding seascape, measured as a function population size accessibility ("gravity"), diminishes effectiveness marine reserves at...
Summary Current global changes make it important to be able predict which interactions will occur in the emerging ecosystems. Most of current methods infer existence between two species require a good knowledge their behaviour or direct observation interactions. In this paper, we overcome these limitations by developing method, inspired from niche model food web structure, using statistical relationship predator and prey body size matrix potential among pool species. The novelty our approach...
The evolutionary dissimilarity between communities (phylogenetic beta diversity PBD) has been increasingly explored by ecologists and biogeographers to assess the relative roles of ecological processes in structuring natural communities. Among PBD measures, PhyloSor UniFrac indices have widely used level turnover lineages over geographical environmental gradients. However, these can be considered as 'broad-sense' measures phylogenetic they incorporate different aspects differences history...
Delineating regions is an important first step in understanding the evolution and biogeography of faunas. However, quantitative approaches are often limited at a global scale, particularly marine realm. Reef fishes most diversified group fishes, compared to other phyla, their taxonomy geographical distributions relatively well known. Based on 169 checklists spread across all tropical oceans, present work aims quantitatively delineate biogeographical entities for reef scale. Four different...
Agricultural land use is a primary driver of environmental impacts on streams. However, the causal processes that shape these operate through multiple pathways and at several spatial scales. This complexity undermines development more effective management approaches, illustrates need for in‐depth studies to assess mechanisms determine changes in stream biodiversity. Here we present results most comprehensive multi‐scale assessment biological condition streams Amazon date, examining...
Functional diversity (FD), the of organism attributes that relates to their interactions with abiotic and biotic environment, has been increasingly used for last two decades in ecology, biogeography conservation. Yet, FD many facets estimations are not standardized nor embedded a single tool. mFD (multifaceted functional diversity) is an R package uses matrices species assemblages trait values as building blocks compute most indices. firstly based on functions allowing user summarize...
