A novel statistical method for classifying habitat generalists and specialists.
We develop a novel statistical approach for classifying generalists and specialists in two distinct habitats. Using a multinomial model based on estimated species relative abundance in two habitats, our method minimizes bias due to differences in sampling intensities between two habitat types as well as bias due to insufficient sampling within each habitat. The method permits a robust statistic...
متن کاملHost specialist clownfishes are environmental niche generalists.
Why generalist and specialist species coexist in nature is a question that has interested evolutionary biologists for a long time. While the coexistence of specialists and generalists exploiting resources on a single ecological dimension has been theoretically and empirically explored, biological systems with multiple resource dimensions (e.g. trophic, ecological) are less well understood. Yet,...
متن کاملContrasts between habitat generalists and specialists: an empirical extension to the basic metacommunity framework.
Emergence of the metacommunity concept has made a substantial contribution to better understanding of the community composition and dynamics in a regional context. However, long-term field data for testing of available metacommunity models are still scarce, and the extent to which these models apply to the real world remains unknown. Tests conducted so far have largely sought to fit data on the...
متن کاملTask Assignments and Incentives: Generalists versus Specialists∗
I develop an agency model of job assignments where jobs differ based on the breadth of tasks. A tradeoff between task complementarities and relative abilities of workers results in those with balanced skills being assigned to multi-task jobs. The same tradeoff between complementarities and relative abilities also influences incentives to sort privately informed workers to jobs. I then draw on a...
متن کاملHabitat generalists and specialists in microbial communities across a terrestrial-freshwater gradient
Observations of distributions of microorganisms and their differences in community composition across habitats provide evidence of biogeographical patterns. However, little is known about the processes controlling transfers across habitat gradients. By analysing the overall microbial community composition (bacteria, fungi, archaea) across a terrestrial-freshwater gradient, the aim of this study...
