This perspective essay considers ethical and conceptual questions around who coexistence is for, it affects, to make happen. The introduction some approaches thinking about human-wildlife coexistence, debates on the utility of concept reasons for its current emergence into mainstream. It next outlines preliminary conception informing this essay. discussion challenges a narrow conservation-orien...
Coexistence of apparently similar species remains an enduring paradox in ecology. Spatial structure has been predicted to enable coexistence even when population-level models predict competitive exclusion if it causes each species to limit its own population more than that of its competitor. Nevertheless, existing hypotheses conflict with regard to whether clustering favours or precludes coexis...
We report Monte Carlo studies of solid-fluid coexistence for the soft-sphere potential: @(r) = e(cr/r)" Applying a recently developed integration method that proceeds along a coexistence line, we determined coexistence for essentially a continuum of softness s —= l/n from s = 0 (hard spheres) to ca. s = 0.25. For s ~ 0.16, we estimate that fcc is the stable crystal, and that bcc is stable for s...
The 790-862 MHz frequency band is allocated for IMT-Advanced system on a co-primary basis operation alongside existing Digital Video BroadcastingTerrestrial (DVB-T), At WRC-07. As a result of frequency spectrum scarcity and emerging various wireless applications, coexistence and sharing between wireless systems become a recently considerable issue. Therefore, coexistence and sharing requirement...
We propose a model for cyclically competing species on continuous space and investigate the effect of the interplay between the interaction range and mobility on coexistence. A transition from coexistence to extinction is uncovered with a strikingly nonmonotonic behavior in the coexistence probability. About the minimum in the probability, switches between spiral and plane-wave patterns arise. ...
Modern coexistence theory and contemporary niche theory represent parallel frameworks for understanding the niche’s role in species coexistence. Despite increasing prominence and shared goals, their compatibility and complementarity have received little attention. This paucity of overlap not only presents an obstacle to newcomers to the field, but it also precludes further conceptual advances a...
Measurements of the coexistence curve and turbidity were made on different molecular mass samples of the branched polymer-solvent system eight-arm star polystyrene in methylcyclohexane near its critical point. We confirmed that these systems belong in the Ising universality class. The location of the critical temperature and composition as well as the correlation length, susceptibility, and coe...
Concurrent niche and neutral processes in the competition-colonization model of species coexistence.
The importance of neutral dynamics is contentiously debated in the ecological literature. This debate focuses on neutral theory's assumption of fitness equivalency among individuals, which conflicts with stabilizing fitness that promotes coexistence through niche differentiation. I take advantage of competition-colonization trade-offs between species of aquatic micro-organisms (protozoans and r...
