Background & Aim: Different species from mint family (Lamiaceae) are used as spices and fragrance in food or as medicine against viral or microbial diseases in many countries for generation. Lamiaceae family contains 46 genus and 410 species. One of the valuable and medicinal species of this family is Ziziphora clinopodioides Lam. This species contains the essential o...

The mechanisms driving the spatial patterns of species richness and composition are essential to the understanding of biodiversity. Numerous studies separately identify the contributions of the environment (niche process) and space (neutral process) to the species richness or composition at different scales, but few studies have investigated the contributions of both types of processes in the t...

A promising shortcut for quantifying species patterns is to use genera and families as surrogates of species. At large spatial scales, concurrence between patterns of richness, rarity, and composition of species and higher taxa is generally high. Only a few researchers, however, have examined this relationship at the local scale, which is frequently the relevant scale in land-use conflicts. We ...

Detailed data on tree species drive models that predict risk of insect and disease mortality in forest stands and simulation models for future stand conditions. Application of such models in geospatial analyses requires these data for millions of remotely sensed pixels. However, the vast majority of remotely sensed thematic maps predict a few categories of stand conditions, such as forest type ...

--Regeneration after clearcutting of Southern Appalachian hardwood stands varies substantially in species composition not only among sites of different quality and previous-stand composition, but also among sites of similar quality and similar previous-stand composition. Severe competition from less desirable species for available growing space is cOllDlon in regenerated stands. The appropriate...

This paper reports a study on species richness and composition of Tumbesian dry forest communities. We tested two alternative hypotheses about species assemblage processes in tropical dry forests: (1) species assemblage is determined by the filtering effect of environmental conditions and (2) species assemblage is determined by facilitative processes along the gradient of water availability, an...
