Accepted Answer

Brooker et al. this paper proposed that cross-scale studies, in which developing an understanding of local-scale processes is as strong an element as understanding regional or global scale processes, and which also consider the interdependence between regional and local scales, seem to be one of the most productive avenues for future research.

Accepted Answer

From this, the authors would propose that crossscale studies, in which developing an understanding of local-scale processes is as strong an element as understanding regional- or global-scale processes, and which also consider the interdependence between regional and local scales, seem to be one of the most productive avenues for future research.. It is not necessary, however, to disintegrate the community concept in order to achieve these goals ; that can be argued for only on the basis of outmoded concepts.

Accepted Answer

Ricklefs focuses particularly on the relationships between local and regional diversity, arguing that if they are strongly correlated, then local-scale processes have relatively little regulatory role.

Accepted Answer

This modeling technique has been a source of considerable debate because of its approach to the relative roles of large-scale versus local processes in regulating distributions and because of its neglect of biology and genetics in determining species’ responses to climate change (and ultimately determining diversity; Hampe 2004; Pearson and Dawson 2004; Guisan and Thuiller 2005; Brooker et al. 2007; O’Neill et al. 2008).

Accepted Answer

The heart of Ricklefs’s specific proposal for disintegrating the community concept appears to be that studying localscale processes does not help us to understand the regulation of species assemblages or diversity on anything other than a very restricted spatial or temporal scale: only by moving away from such work (which at the same time, he argues, necessitates abandoning the local community concept) can the authors understand the processes that regulate large-scale patterns of diversity and coexistence.

Accepted Answer

the lower species richness of subalpine communities on mesic siliceous soils of the French Alps is demonstrably the result of competitive exclusion of stress-tolerant “calcareous species” by competitive “siliceous species” (Choler et al. 2001; Michalet et al. 2002).

Accepted Answer

it has been argued by Michalet et al. (2006) and shown by Liancourt et al. (2005) that facilitation of stress-intolerant species by stress-tolerants further contributes to the species richness of communities on calcareous substrates.

Accepted Answer

abandoning the study of interactions at the community level would significantly limit their ability to explain species coexistence and biodiversity in many environments.

Accepted Answer

They showed that, when an appropriate null model was applied, climate envelope models were significantly better than the null at modeling species distributions for only 32 out of the 100 species examined.

Accepted Answer

The Clements-Gleason dichotomy has heuristic value, but it is essential that the authors move beyond it by exploring the new, emergent properties and processes that arise when species live together in an integrative manner—where the issue of the boundaries of communities is really secondary—especially at a time when integration among fields is essential for dealing with current environmental challenges.

Accepted Answer

it is unlikely that these species pools emerged ex nihilo and that contemporary evolution is “waiting” for continental drift to occur before affecting changes in pool composition.
