Ecosystem level carbon and net primary productivity (NPP) estimates for old-growth and regenerating tropical forests of India are lacking. The study was conducted to estimate ecosystem level carbon contents and NPP, based on above and below ground biomass of trees, shrubs and herbs in an old growth and a regenerating humid tropical forest of Nongkhyllem Wildlife Sanctuary, Meghalaya in north-eastern India. Soil carbon contents were also estimated in both the forest types to estimate ecosystem level carbon. The tree above ground biomass values in old-growth and regenerating forests were 313.8 and 152.4 Mg ha-1 and the below ground values were 50.8 and 30.3 Mg ha-1, respectively. The corresponding total above ground biomass values including trees, litter, herb and shrub components were 323.7 and 159.3 Mg ha-1, respectively. Of the total ecosystem biomass values of 374.5 Mg ha-1 in the old-growth forest, 86% was in the above ground and 14% was in the below ground compartment. The corresponding proportions in the regenerating forest with total biomass of 189.6 Mg ha-1 were 84% and 16%, respectively. The total ecosystem carbon contents in old-growth and regenerating forests were 265.5 and 147.8 Mg C ha-1, of which soil organic carbon was 83.2 and 55.6 Mg C ha-1, respectively that contributed 31.3% and 37.6% to the total ecosystem carbon in the respective forests. However, ecosystem NPP in the regenerating forest (18.4 Mg ha-1 yr-1) was greater than the old growth forest(13.6 Mg ha-1 yr-1)

Large expanses of tropical rainforest have been converted into agricultural landscapes cultivated by smallholder farmers. This is also the case in north-eastern Madagascar; a region that retains a significant proportions of forest cover despite shifting hill rice cultivation and vanilla agroforestry. The region is also a global hotspot for herpetofauna diversity, but how this diversity is affected by land-use change remains largely unknown. Using a space-for-time study design to uncover land-use effects, we compared species diversity and community composition in seven prevalent land uses: unburned (old-growth forest, forest fragment, and forest-derived vanilla agroforest) and burned (fallow-derived vanilla agroforest, woody fallow, herbaceous fallow) land-use types, and rice paddy. We conducted six comprehensives, time-standardized searches across at least ten replicates of each land-use type and applied genetic barcoding to confirm species identification. We documented an outstanding diversity of endemic herpetofauna (119 species): amphibian species richness at the plot level was highest in old-growth forest and significantly lower in all other land-use types. Plot-level reptile species richness was significantly higher in the unburned land-use types than burned land-use types. For both amphibians and reptiles, the less-disturbed land-use types showed more uneven communities and particularly in old-growth forest, the species composition differed significantly from all other land-use types. Amphibians showed a higher level of forest dependency compared to reptiles (38% versus 28% of species exclusively occurred in old-growth forest). Our analyses thus revealed that the two groups respond differently to land-use change: we found less pronounced losses of reptile species richness especially in unburned agricultural habitats, suggesting that reptiles are less susceptible to land-use change than amphibians. Overall, old-growth forest harboured a unique diversity, but some species also thrived in agroforestry systems, especially if these were forest-derived. This highlights the importance of conserving old-growth forests and non-burned land-use types within the agricultural landscape.

AbstractUnderstanding how land-use change affects biodiversity is a fundamental step to develop effective conservation strategies in human-modified tropical landscapes. Here, we analyzed how land-use change through tropical small-scale agriculture affects endemic, exotic, and non-endemic native ant communities, focusing on vanilla landscapes in north-eastern Madagascar, a global biodiversity hotspot. First, we compared ant species richness and species composition across seven land-use types: old-growth forest, forest fragment, forest-derived vanilla agroforest, fallow-derived vanilla agroforest, woody fallow, herbaceous fallow, and rice paddy. Second, we assessed how environmental factors drive ant species richness in the agricultural matrix to identify management options that promote endemic and non-endemic native while controlling exotic ant species. We found that old-growth forest, forest fragment, and forest-derived vanilla agroforest supported the highest endemic ant species richness. Exotic ant species richness, by contrast, was lowest in old-growth forest but highest in herbaceous fallows, woody fallows, and rice paddy. Rice paddy had the lowest non-endemic native ant species richness. Ant species composition differed among land-use types, highlighting the uniqueness of old-growth forest in harboring endemic ant species which are more sensitive to disturbance. In the agricultural matrix, higher canopy closure and landscape forest cover were associated with an increase of endemic ant species richness but a decrease of exotic ant species richness. We conclude that preserving remnant forest fragments and promoting vanilla agroforests with a greater canopy closure in the agricultural matrix are important management strategies to complement the role of old-growth forests for endemic ant conservation in north-eastern Madagascar.

Abstract Kokowska-Pawłowska, M. and Nowak, J. 2013. Phosphorus minerals in tonstein; coal seam 405 at Sośnica- Makoszowy coal mine, Upper Silesia, southern Poland. Acta Geologica Polonica, 63 (2), 271-281. Warszawa. The paper presents results of research on tonstein, which constitutes an interburden in coal seam 405 at the Sośnica- Makoszowy coal mine, Makoszowy field (mining level 600 m), Upper Silesia, southern Poland. The mineral and chemical compositions of the tonstein differ from the typical compositions described earlier for tonsteins from Upper Silesia Coal Basin area. Additionally, minerals present in the tonsteins include kaolinite, quartz, kaolinitised biotite and feldspars. The presence of the phosphatic minerals apatite and goyazite has been recognized. The presence of gorceixite and crandallite is also possible. The contents of CaO (5.66 wt%) and P2O5 (6.2 wt%) are remarkably high. Analysis of selected trace elements demonstrated high contents of Sr (4937 ppm) and Ba (4300 ppm), related to the phosphatic minerals. On the basis of mineral composition the tonstein has been identified as a crystalline tonstein, transitional to a multiplied one.

Basic Characteristics

Old-growth forest reserves in Slovenia: the past, present, and future Slovenia has a small number of old-growth forest remnants, as well as many forest reserves approaching old-growth conditions. In this paper, we describe some of the basic characteristics of these old-growth remnants and the history of their protection in Slovenia. We then trace the long-term development of research in these old-growth remnants, with a focus on methodological changes. We also review some of the recent findings from old-growth research in Slovenia and discuss future research needs. The conceptual understanding of how these forests work has slowly evolved, from thinking of them in terms of stable systems to more dynamic and unpredictable ones due to the influence of natural disturbances and indirect human influences. In accordance with this thinking, the methods used to study old-growth forests have changed from descriptions of stand structure to studies that address natural processes and ecosystem functions.
