Coexistence of the niche and neutral perspectives in community ecology.
The neutral theory for community structure and biodiversity is dependent on the assumption that species are equivalent to each other in all important ecological respects. We explore what this concept of equivalence means in ecological communities, how such species may arise evolutionarily, and how the possibility of ecological equivalents relates to previous ideas about niche differentiation. W...
متن کاملPlant coexistence and the niche
a Diversity: the number of species found in a local community. a Niche: the region of the realized niche of a species corresponding to species diversity at the local community (or a-diversity) scale at which interactions among species occur. Niche differences at this scale should facilitate coexistence. Character displacement: the evolutionary accentuation of trait differences between sympatric...
متن کاملDisturbance and change in biodiversity.
Understanding how disturbance affects biodiversity is important for both fundamental and applied reasons. Here, I investigate how disturbances with different ecological effects change biodiversity metrics. I define three main types of disturbance effects: D disturbance (shifts in mortality rate), B disturbance (shifts in reproductive rates) and K disturbance (shifts in carrying capacity). Numer...
متن کاملFungal Biodiversity in the Alpine Tarfala Valley
Biological soil crusts (BSCs) are distributed worldwide in all semiarid and arid lands, where they play a determinant role in element cycling and soil development. Although much work has concentrated on BSC microbial communities, free-living fungi have been hitherto largely overlooked. The aim of this study was to examine the fungal biodiversity, by cultural-dependent and cultural-independent a...
متن کاملNiche differentiation in the dynamics of host-symbiont interactions: symbiont prevalence as a coexistence problem.
Heritable symbioses can have important ecological effects and have triggered important evolutionary innovations. Current predictions for long-term symbiont prevalence are based on their fitness benefits and vertical transmission rates but ignore nonlinear competitive feedbacks among symbiotic and symbiont-free hosts. We hypothesized that such feedbacks function as stabilizing mechanisms, promot...
