  abstract = {{W}e describe the mesoscale floristic patterns in the central {W}estern {G}hats of {K}arnataka, {I}ndia, through combined analysis of woody species abundance and stand structure data from a network of ninety-six 1-ha sampling plots spread across 22,000 km2. {A} total of 61,906 individuals (>= 10 cm gbh) comprising 400 plant species from 254 genera and 75 families were recorded. {E}uphorbiaceae, {R}ubiaceae, {L}auraceae and {M}oraceae families constituted 23.5 percent of the total number of species encountered. {T}he relative dominance of species was skewed with {P}oecilonueron indicum, {X}ylia xylocarpa, {T}erminalia tomentosa and {A}nogeissus latifolia being dominant in some plots. {C}orrespondence analysis ({CA}) and a nonmetric multidimensional scaling ({NMDS}) of plots by species abundances data showed similar arching patterns, with significant correlation between the first axis of {CA} and {NMDS} (r=0.77). {H}ierarchical clustering of plot scores along the three first {CA} axes resulted in splitting the plots into five different categories that broadly reflect the major bioclimatic features of the region. {A} multiscale bootstrapping test indicated that categorization of the wettest (wet evergreen group 1 and 2) and driest (dry deciduous) groups were robust ({P} < 0.05 with 1000 bootstraps), while the remaining two transitional groups were uncertain ({P}=0.12 and 0.26 for moist deciduous and semi-evergreen group, respectively). {P}rincipal component analysis revealed that plots with similar floristic composition can encompass contrastingly different physiognomic structures (canopy cover, canopy height and mean tree diameter) probably in relation to their levels of disturbance. {O}bserved patterns in the floristic composition have been discussed in the light of the complex interaction between the bioclimatic and disturbance regimes that characterize the region.},
