1 The recruitment stage can be critical in determining plant population dynamics, as juveniles encounter a range of abiotic and biotic stressors in the environments where they land after dispersal, and often experience high mortality rates. Alth[...]

1 The arctic environment is highly heterogeneous in terms of plant distribution and productivity. If we are to make regional scale predictions of carbon exchange it is necessary to find robust relationships that can simplify this variability. On[...]

1 Prolonged dormancy, a condition in which herbaceous perennial plants do not sprout for more than a year, has only been described to any great extent in long-lived clonal species, particularly in the family Orchidaceae. However, some short-live[...]

1 Invertebrate grazing during the regeneration phase is well known to exert a strong structuring effect in terrestrial plant communities. However, very few studies have investigated the effect of invertebrate herbivores on regenerating freshwate[...]

1 The seasonal timing of flower production is a critical event in the life cycle of many plants. A range of abiotic and biotic interactions has been suggested to influence the optimal flowering phenology. More rarely, phenology has been examined[...]

1 Metacommunity and neutral theory have reinvigorated the study of 'niches' and have emphasized the importance of understanding the influences of competition, abiotic factors and regional spatial processes in shaping communities. 2 We conducted [...]

1 We examined whether two different grassland microhabitats forming a stable mosaic (anthills and surrounding grassland) are colonized by different genotypes of a common grass, Agrostis capillaris, and thus maintain genetic variation in the spec[...]

In plant communities, invasion resistance may increase with diversity because empty niche space decreases simultaneously. However, it is not clear if this only applies to exotic species or also to native species arriving at a site with few other[...]

1 We examined the factors determining synchrony in reproduction in nine Acacia and six other tree species in the Serengeti ecosystem. 2 We test two hypotheses: (i) an abiotic hypothesis where the primary determinant of synchrony is an adaptation[...]

1 We tested the hypothesis that the competitive effect of multi-species mixtures on a single target plant can be described as a simple additive function of the effects of single species. 2 In a controlled field competition experiment on sand, we[...]
