“…The results will provide useful information for ecological protection and redevelopment in this region. In addition, karst landform covers about one-tenth of earth surface [21], and many karst regions have suffered degradation due to increasing human activities coupled with highly vulnerable eco-geo-environment [22][23][24], thus this study may also provide highlights for other karst areas.…”

Abstract:The Southwest China Karst, the largest continuous karst zone in the world, has suffered serious rock desertification due to the large population pressure in the area. Recent trend analyses have indicated general greening trends in this region. The region has experienced mild climate change, and yet significant land use changes, such as afforestation and reforestation. In addition, out-migration has occurred. Whether climate change or human-induced factors, i.e., ecological afforestation projects and out-migration have primarily promoted forest restoration in this region was investigated in this study, using Guizhou Province as the study area. Based on Moderate-Resolution Imaging Spectroradiometer (MODIS) Normalized Difference Vegetation Index (NDVI) data, we found general greening trends of the forest from 2000 to 2010. About 89% of the forests have experienced an increase in the annual NDVI, and among which, about 41% is statistically significant. For the summer season, more than 65% of the forests have increases in summer NDVI, and about 16% of the increases are significant. The strongest greening trends mainly occurred in the karst areas. Meanwhile, annual average and summer average temperature in this region have increased and the precipitation in most of the region has decreased, although most of these changes were not statistically significant (p > 0.1). A site-based regression analysis using 19 climate stations with minimum land use OPEN ACCESS Remote Sens. 2014, 6 9896 changes showed that a warming climate coupled with a decrease in precipitation explained some of the changes in the forest NDVI, but the results were not conclusive. The major changes were attributed to human-induced factors, especially in the karst areas. The implications of an ecological afforestation project and out-migration for forest restoration were also discussed, and the need for further investigations at the household level to better understand the out-migration-environment relationship was identified.

: Two new Chamaecytisus species (Leguminosae-Papilionoideae) from Albania, with an overview on the Ch. ratisbonensis and Ch. eriocarpus species groups. -Studia bot. hung. 47(1): 163-178. Abstract:Two new species, Chamaecytisus korabensis and Ch. pseudojankae, both from Albania, are described and illustrated here. Th e relationship of the new taxa to Ch. ratisbonensis and Ch. eriocarpus agg. is discussed. Ch. korabensis is an endemic species of eastern Albania and related to the Eastern European Ch. ratisbonensis agg. Ch. pseudojankae is an endemic species of the Th atë and Galičica Mountain ranges, and morphologically it is between Ch. austriacus and Ch. eriocarpus agg. Additionally, the names Cytisus absinthioides and C. pygmaeus are lectotypifi ed.

“…Major research efforts traditionally aim to understand hydrologic and hydrogeological processes in carbonate media (White, 1988;EC, 1995;Ford & Williams, 2007), and many techniques have been customized to that end (Goldscheider & Drew, 2007). In contrast, less attention has been paid to investigations focused on evaporitic karst formations, particularly those hosted throughout the Mediterranean area (Klimchouk et al, 1996;Gutiérrez et al, 2008;Liguori et al, 2008;Parise et al, 2008). Such studies generally address speleogenetic and karstological issues (Johnson, 1997;Klimchouk & Aksem, 2005;Gutiérrez et al, 2008), or natural and human-induced geo-hazards (Galve et al, 2009;Gutiérrez et al, 2014).…”

Abstract:The geomorphological characteristics and hydrogeological functioning of a geologically heterogeneous evaporitic karst plateau in Southern Spain were studied. Land surface information (LiDAR data) was used to analyze the shape and distribution of closed depressions. An artificial tracer test and monitoring of the natural responses of the main spring have allowed to infer the karstic development of the studied system. Three dyes were injected in selected swallow holes to trace the main groundwater flowpaths and to estimate the dimension of the conduit network. Discharge, electrical conductivity and temperature were monitored in the groundwater that drains the evaporitic plateau during an individual and intense recharge pulse. Tracing techniques were adapted to high salinity environments by using specific calibration standards (NaCl + dye). The hydrological connection detected between two of the swallow holes and the outlet, and the deduced orientation pattern for closed areas, would suggest that the karst evolution (internal and external) is related to fault orientation. The rapid tracer detection (16-20 h) and high estimated maximum flow velocities (125-192 m/h), together with the fast impulsional response of the controlled physicalchemical parameters in spring waters (~15-16 h) demonstrate the existence of quick flows under recharge conditions with well-defined system drainage, indicating a high degree of internal karstification (estimated master conduit diameter ~1.5 m). However, flooding of the depressions feeding swallow holes and analysis of the spring response times from natural and artificial tracers point to a restriction of the system´s drainage, most likely due to the constrained morphology of the karst conduits. This results in sustained recharge periods and delayed spring responses of some parameters, highlighting the relevant role of concentrated recharge in the hydrogeological behavior of the studied evaporitic karst.
