1. Considering that the spatial pattern of trees is a footprint of the biological processes that drive their dynamics, increasing work has been undertaken to analyse spatial patterns and fit spatial point processes to them. When diameter is take[...]

1. Rees Journal of Ecology, 95, 926-936) correctly identified scaling relations across species between offspring size at independence and adult size as patterns needing theoretical explanation. They also correctly identified that Charnov's (199[...]

Optimal defence theory predicts investment in extrafloral nectar resources in an ant-plant mutualism
J. Nathaniel Holland, Auteur ;

1. Nearly all mutualisms entail the production of resources by one species that attract and reward the species with which it interacts. As such resource production could otherwise be allocated to growth or reproduction, mutualists are predicted [...]

1. Fridley et al. (2007) introduced a technique of species habitat specialization assessment based on co-occurrence analysis of large species-plot matrixes, with a continuous metric (theta value) intended to reflect relative species niche width.[...]

1. Plant defence theory predicts that chemical defences should be optimally deployed to protect against herbivore damage, but avoid production costs when herbivores are rare. However, many chemicals involved in herbivore defence are also involve[...]

1. Variations in disturbance regime strongly influence ecosystem structure and function. A prominent form of such variation is when multiple high-severity wildfires occur in rapid succession (i.e. short-interval (SI) severe fires, or 're-burns')[...]

1. Sea-level rise, one indirect consequence of increasing atmospheric CO(2), poses a major challenge to long-term stability of coastal wetlands. An important question is whether direct effects of elevated CO(2) on the capacity of marsh plants to[...]

1. Metapopulation dynamics - the recurrent extinction and colonization in spatially discrete habitats - is expected to strongly affect within and between population genetic diversity. So far, however, accounts of true plant metapopulations are e[...]

1. Plant functional composition may indirectly affect fine root processes both qualitatively (e.g. by influencing root chemistry) and quantitatively (e.g. by influencing root biomass and thus soil carbon (C) inputs and the soil environment). Des[...]
