Weak Competition Among Tropical Tree Seedlings: Implications for Species Coexistence
The intensity of competition among forest tree seedlings is poorly understood, but has important ramifications for their recruitment and for the maintenance of species diversity. Intense competition among seedlings could allow competitively dominant species to exclude subordinate species. Alternatively, the low density and small stature of forest tree seedlings could preclude intense interseedl...
متن کاملNitrogen allocation and partitioning in invasive and native Eupatorium species.
There is a trade-off between nitrogen (N) allocation to photosynthesis and to defence. Invasive species may reduce N allocation to defence because of the absence of natural enemies. Thus, I hypothesised that invasive species may allocate a higher fraction of total leaf N to photosynthesis and have higher light-saturated photosynthetic rate (P(max)) and photosynthetic N-use efficiency (PNUE) tha...
متن کاملCompetition for shelter between four invasive gobiids and two native benthic fish species
Recent invasions by non-native gobiid fish species that are ongoing in the Western European rivers Rhine and Meuse, will lead to interactions with native benthic fish species. Since both non-native gobiids and native benthic species are bottom dwelling species with a preference for shelter during at least part of their life cycle, it is likely that competition for shelter will occur between the...
متن کاملCompetition for nitrogen between Fagus sylvatica and Acer pseudoplatanus seedlings depends on soil nitrogen availability
Competition for nitrogen (N), particularly in resource-limited habitats, might be avoided by different N acquisition strategies of plants. In our study, we investigated whether slow-growing European beech and fast-growing sycamore maple seedlings avoid competition for growth-limiting N by different N uptake patterns and the potential alteration by soil N availability in a microcosm experiment. ...
متن کاملPriority effects determine the outcome of ectomycorrhizal competition between two Rhizopogon species colonizing Pinus muricata seedlings.
Competition is often considered a fundamental process influencing assemblage structure, yet little is known about competition among ectomycorrhizal (EM) fungi. Here, we examine competitive interactions between Rhizopogon occidentalis and Rhizopogon salebrosus in a 6-month microcosm study. Pinus muricata seedlings were grown in three EM treatments: R. occidentalis, R. salebrosus, and R. occident...
