Functional diversity: back to basics and looking forward.
TLDR
It is suggested that non-significant results have a range of alternate explanations that do not necessarily contradict positive effects of functional diversity, and areas for development of techniques used to measure functional diversity are suggested. Expand
Functional diversity (FD), species richness and community composition
TLDR
A means for quantifying functional diversity that may be particularly useful for determining how functional diversity is related to ecosystem functioning is proposed, defined as the total branch length of a functional dendrogram. Expand
Environmental warming alters food-web structure and ecosystem function
TLDR
It is shown using microcosm experiments that extinction risk in warming environments depends on trophic position but remains unaffected by biodiversity, which suggests that high biodiversity buffers against the effects of environmental variation because tolerant species are more likely to be found. Expand
Size, foraging, and food web structure
TLDR
The model results support the hypothesis that individual behavior, subject to natural selection, determines individual diets and that food web structure is the sum of these individual decisions. Expand
Low functional diversity and no redundancy in British avian assemblages.
TLDR
It is suggested that community assembly is influenced by the traits of species and that observed changes in functional diversity provide no reason to believe that the functioning of natural systems is buffered against change by ecological redundancy. Expand
Biodiversity and Resilience of Ecosystem Functions.
TLDR
A range of mechanisms underpinning the resilience of ecosystem functions across three ecological scales are identified and biodiversity, encompassing variation from within species to across landscapes, may be crucial for the longer-term resilience ofcosystem functions and the services that they underpin. Expand
Interaction strengths in food webs: issues and opportunities
TLDR
The various ways in which the term ‘interaction strength’ has been applied are described and the implications of loose terminology and definition for the development of this field are discussed. Expand
Universal temperature and body-mass scaling of feeding rates
TLDR
These body-mass- and temperature-scaling models remain useful as a mechanistic basis for predicting the consequences of warming for interaction strengths, population dynamics and network stability across communities differing in their size structure. Expand
Effects on population persistence: the interaction between environmental noise colour, intraspecific competition and space
It is accepted that accurate estimation of risk of population extinction, or persistence time, requires prediction of the effect of fluctuations in the environment on population dynamics. Generally,Expand

TLDR
Using a continuous measure of functional diversity derived from the quantitative functional traits of species, it is shown that the loss offunctional diversity from six natural assemblages was rapid compared with rates of loss from comparable simulated assemblage. Expand
