“…The mountain ridges among river valleys are covered by dense forests. Mountain riparian zones are crucial refuges for Tertiary relict plants in this area (Jiang et al 2002;Wei et al 2010). The Yandu River originates in the south-facing slope of the Shennongjia Mountains and is a tributary of the Yangtze River.…”

“…The upper reaches of the Yandu River are relatively unaffected by human disturbance owing to inaccessibility. In this area, E. pleiospermum is one of the dominant relict tree species in the riparian forests at elevation between~1200 and 1900 m (Wei et al , 2010. In May 2012, a total of 240 E. pleiospermum plants were sampled from 12 (six at headwaters and six at confluences) discrete locations along three adjacent catchments (each with four populations) at the upper reaches of the Yandu River ( Fig.…”

Riparian landscapes are dendritic in nature. However, much attention on genetic structure of riparian plants has been paid to linear models of connectivity while studies that investigate the influence of dendritic landscape are scarce. In this study, we used nuclear microsatellite markers to investigate genetic diversity, gene flow, and genetic structure of a streamside tree species (Euptelea pleiospermum) in a natural stream dendritic network in the Shennongjia Mountains, central China. We tested the following hypotheses: (1) genetic diversity is higher at confluence than that at headwater populations and (2) genetic structure within the stream dendritic network was determined by in-stream dispersal or out-of-stream dispersal. Contrary to our prediction, we found that both genetic diversity and effective population size are congruent at headwater and confluence populations. We found symmetrical gene flow in most (four out of six) headwater-confluence pairs and asymmetrically downstream gene flow in the other two headwater-confluence pairs. Analysis of molecular variance (AMOVA) detected significant differentiation at two scales (among streams within catchments, among populations within stream) and did not reveal significant structure among catchments. STRU CTURE analysis clustered individuals from different catchments into the same genetically homogeneous group. There was no significant isolation by distance (IBD) with Euclidean, stream, or overland distance. Our results suggest that E. pleiospermum populations within the stream dendritic network did not present a hierarchical genetic structure probably because of extensive out-of-stream dispersal.

Cercidiphyllum japonicum is a rare endemic species of East Asia flora and a common component in riparian forests. Dendrochronological techniques were employed to trace radial growth of C. japonicum in the Shennongjia area of central China and examine its relationships with local climate. Effects of precipitation on width of C. japonicum annual rings were negligible except for some temporary negative impacts in prior winter. The variables most strongly controlling radial growth were temperatures in the previous December and during the current summer. Relationships for most pairs of ring-width and monthly/seasonal climate variables were temporally unstable but occasionally significant. Radial growth-climate relationships for C. japonicum were likely shaped by riparian site characteristics, root habits, and regional climatic regimes.

Aim: Methodology:Results: Interpretation:The fundamental information layers of ecosystem -based management plans are obtained by calculating, modeling and mapping of biodiversity. This study was carried out to calculate and map of landscape diversity in the Kuyucak Mountain District, in the transition zone of the Mediterranean region.Topographical diversity values of altitude, slope degree and radiation index for each cell (752.09 × 752.09 m) of Kuyucak Mountain District were calculated using Shannon Wiener, Simpson diversity, Renyi H and Rao indices. The index for each variable topographic map, which was prepared 2 using cellular values after the calculations was obtained by Geographic Information Systems.The maps illustrating diversities of topographical variables were prepared in order to obtain more accurate model -based distribution map of biodiversity.Climate, topography and soil properties play important roles on biodiversity. There are also significant relationships between landscape diversity and biodiversity. That is why it is important to prepare not only climatic, topographic and soil maps but also diversity maps as explanatory variables for modeling and mapping of biodiversity.
