“…These results support other studies that reported oaks were more abundant on southern and western aspects (Keever, 1953;McCarthy et al, 1984;Steiner et al, 1993). Our work builds on these previous studies because we demonstrate that the correlation between aspect and oak abundance was significant even when other factors are also considered (Tables 1 and 2; but see Hannah, 1968).…”

“…White oak adult and sapling densities were highest on southern and southwestern slopes, as also reported by Keever (1953) and McCarthy et al (1984). Likewise, chestnut oak adult and sapling densities were greater on upper slopes and ridge tops, which is in agreement with the findings of Whittaker (1956), Buell et al (1966) and Lorimer (1980).…”

“…Juveniles, however, are often rare on these sites and are more common on low productivity, xeric, and ridge tops sites (Lorimer, 1984;Lorimer, 1985;Nigh et al, 1985;Crow, 1988;Pallardy et al, 1988;Lorimer et al, 1994). White oak adults and juveniles are found in higher abundances on south facing, drier sites (Keever, 1953;McCarthy et al, 1984; , 1988, , Nowacki et al, 1990. Chestnut oak, both adults and juveniles, occur in higher relative abundances on xeric, low productivity, ridge top sites (Keever, 1953;Whittaker, 1956;Lorimer, 1980;Abrams et al, 1997).…”

“…Indeed, long-lived oriental beech trees can reach more than 2 meters in diameter at productive sites, and show a high amount of forest dead wood in the studied sites (Sefidi & Etemad 2012, Moradi et al 2012. The influence of topography on forest stand composition has been demonstrated in North America (McCarthy et al 1984, Rubino & McCarthy 2003, and similar evidence was also reported in Europe (Garcia et al 2007) and in Iran (Mohsennezhad et al 2010, Valipour et al 2013). In the Caspian region, the most productive sites are located on the northern slopes.…”

There is an emerging interest in the relationships between forest structure and topographic aspects. Still, such patterns have been scarcely studied in undisturbed mixed beech forests in northern Iran. We investigated the influence of topographical factors including aspect, slope degree, and landform index (LI) on the distribution of dominant tree species and coarse woody debris (CWD). Tree density and basal area were not significantly correlated with any of the measured parameters, except a moderate relation between basal area and LI (r = -0.376; P = 0.029). Redundancy analysis (RDA) of the tree layer revealed a significant relationship between the measured environmental variables and species distributions. CWD volume showed significant negative correlation with percent canopy coverage and was highly correlated with slope. Density of CWD in decay class IV was significantly correlated with aspect and percent of canopy cover. Analyses of CWD distributions in relation to both living vegetation and topographic gradients showed a highly complex interplay of factors driving the distribution of CWD across the forest stands.

“…Though soil fertility was not assessed here, but soil reaction (pH) did exhibit a strong negative correlation coefficient of x-axis with sites groupings in the present study. That vegetation distribution is controlled by the type of aspect -moisture related gradient was also found by McCarthy et al (1984) in upper slope oak hickory stands of southeastern Ohio, and by Koenigs et al (1982) in semi arid watersheds of lake Berryessa in USA. The above cited studies were across visible gradients while the present study considered 127 samples spread over the area without, a priori, knowing or considering any gradients whatsoever.…”

Vegetation of 127 sites on different aspects of dune-interdunes in the Indian Thar Desert was classified using TWINSPAN. TWINSPAN groupings of sites separated better vegetated dunes of the northeast form the poorly vegetated dunes of the northwest and the southwest. Of the different ordinations using noncentred, centred and centred and standardized principal component analysis, reciprocal averaging and detrended correspondence analysis (DCA), the site and species classes in DCA correlated well with ten edaphic and ten vegetational attributes of each site. Strong correlation of vegetation groupings with soil texture, moisture holding capacity and low correlation with pH and electrical conductivity revealed the possible importance of soil physical properties in affecting vegetation composition.The 11 species classes in TWlNSPAN were regrouped into 18 species classes in DCA, which separated highly frequent species from those of less and least frequent species. Based on dominance-diversity attributes, Calligonum polygonoides-Lasiurus sindicus was brought out as bioedaphic climax stage. Correlation of ordination scores in different site groupings with vegetational attributes showed specific trends: From the zero of x, y and z axes to their maximum, the ordination scores of grasses and browse species declined while score of spinous species increased. The sites near the origin of the x, y and z axes were therefore least degraded and those at or near the maximum of x, y & z axes were most disturbed as was confirmed by the dominance diversity trends. Thus trends of compositional and functional attributes of vegetation of sites in different groupings helped in inferring a site's degradation status.
