1. Wood-decaying fungi are ubiquitous and functionally important organisms within forest ecosystems world-wide, but remarkably little is known of their population dynamics in relation to the dynamics of their host substrates. Living in transient[...]

1. A plant producing secondary compounds may affect the fitness of other plants in the vicinity, and, likewise, associated plants may evolve adaptation to the presence of their 'chemical neighbour'. Species of the genus Thymus are aromatic plant[...]

1. One mechanism explaining the success of invasive weeds may be the production and release of allelopathic compounds by the invader that, due to a lack of co-evolutionary history, have harmful effects on plant neighbours in the introduced range[...]

1. Habitat fragmentation and variation in habitat quality can both affect plant performance, but their effects have rarely been studied in combination. We thus examined plant performance in response to differences in habitat quality for a specie[...]

1. The major aim of this paper was to explore the mechanistic basis of induced defensive ant response in myrmecophytic Piper species and their ant-partner Pheidole bicornis by combining experimental trials and chemical analysis. 2. In field expe[...]

1. Plant defence theory predicts trade-offs among defence traits as a result of resource limitation or pleiotropic effects. Although theoretically widely accepted, empirical demonstrations of such trade-offs are surprisingly scarce and mechanist[...]

1. Tropical forests have highly diverse and often dense understorey vegetation. However, little is known about the demography of tropical understorey species and their response to common events like flooding and gap formation that change the pre[...]

1. Species diversity and genetic diversity are fundamental components of biodiversity. A primary goal of biodiversity studies is to explain the distribution of species and alleles in space and time. A new challenge is to cross discipline boundar[...]

1. Analyzing the phylogenetic structure of natural communities may illuminate the processes governing the assembly and coexistence of species. For instance, an association between species co-occurrence in local communities and their phylogenetic[...]

1. Competition is a key factor affecting the performance and co-existence of species. Most ecological research on competition treats species' populations as phenotypically homogenous. However, plant populations typically contain genetic variatio[...]

1. Experimental studies have provided significant knowledge of how biodiversity can influence ecosystem processes. However, there is a growing need to relate these findings to natural communities. 2. Here we identify two major hypotheses for how[...]

1. Ecologists have generally focused on how species interactions and available niches control species richness. However, the number of species in the regional species pool may also control richness. Moreover, the relative influence of the specie[...]

1. As urbanization accelerates, interest is growing in the traits of urban plants. We classified 822 UK vascular plants on the basis of their occurrence along an urban-rural gradient in 26 710 samples of vegetation from 2508 UK 1-km grid squares[...]
