Organic pollutants in stream sediments of Kupa River drainage basin, 2005, Franciskovicbilinski S, Bilinski H, Sirac S,
This paper presents the first results of distribution of organic pollutants in 44 sediment samples (fraction < 63 mu m) of Kupa River drainage basin, which is a significant water resource for Croatia, Slovenia and BiH (Bosnia and Herzegovina). The investigated region aimed to be used as a model for future studies, necessary to meet Decision No. 2455/2001/EC. Some parts of the drainage basin are national parks (Risnjak and Plitvice Lakes). Also, a great part was affected by war 1991-1995 and is still under mines, what makes it difficult to sample. Sediments have shown a good record of pollution. Concentrations of total polychlorinated biphenyls (PCBs) were found above toxic levels (> 0.02 ppm) for 7 sediment samples. Total phenols were determined above 0.65 ppm for 23 sediment samples, which was characterized as heavily polluted sites. Mineral oils above 100 ppm were found in 13 sediment samples, which are, therefore, moderately polluted. Total lindane isomers in all sediments were below the detection limit of 0.0004 ppm, and, therefore, far below the toxic level of 0.0009 ppm. Results have shown unexpectedly that the western part of Kupa River drainage basin, with karst aquifers of high risk located in the boarder area of Croatia and Slovenia, has sediments, which were more polluted with organic contaminants from those affected by the war in the middle and eastern part of the basin. Further studies of sediments and protection of karst aquifers in this region is suggested

Geomicrobiology of cave ferromanganese deposits: A field and laboratory investigation, 2005, Spilde M. N. , Northup D. E. , Boston P. J. , Schelble R. T. , Dano K. E. , Crossey L. J. , Dahm C. N. ,
Unusual ferromanganese deposits are found in several caves in New Mexico. The deposits are enriched in iron and manganese by as much as three orders of magnitude over the bedrock, differing significantly in mineralogy and chemistry from bedrock-derived insoluble residue. The deposits contain metabolically active microbial communities. Enrichment cultures inoculated from the ferromanganese deposits produced manganese oxides that were initially amorphous but developed into crystalline minerals over an 8-month period and beyond; no such progression occurred in killed controls. Phylogenetic analyses of sequences from clone libraries constructed from culture DNA identified two genera known to oxidize manganese, but most clones represent previously unknown manganese oxidizers. We suggest that this community is breaking down the bedrock and accumulating iron and manganese oxides in an oligotrophic environment

Land use change and soil nutrient transformations in the Los Haitises region of the Dominican Republic, 2005, Templer P. H. , Groffman P. M. , Flecker A. S. , Power A. G. ,
We characterized soil cation, carbon (C) and nitrogen (N) transformations within a variety of land use types in the karst region of the northeastern Dominican Republic. We examined a range of soil pools and fluxes during the wet and dry seasons in undisturbed forest, regenerating forest and active agricultural sites within and directly adjacent to Los Haitises National Park. Soil moisture, soil organic matter (SOM), soil cations, leaf litter C and pH were significantly greater in regenerating forest sites than agricultural sites, while bulk density was greater in active agricultural sites. Potential denitrification, microbial biomass C and N, and microbial respiration g(-1) dry soil were significantly greater in the regenerating forest sites than in the active agricultural sites. However, net mineralization, net nitrification, microbial biomass C, and microbial respiration were all significantly greater in the agricultural sites on g(-1) SOM basis. These results suggest that land use is indirectly affecting microbial activity and C storage through its effect on SOM quality and quantity. While agriculture can significantly decrease soil fertility, it appears that the trend can begin to rapidly reverse with the abandonment of agriculture and the subsequent regeneration of forest. The regenerating forest soils were taken out of agricultural use only 5-7 years before our study and already have soil properties and processes similar to an undisturbed old forest site. Compared to undisturbed mogote forest sites, regenerating sites had smaller amounts of SOM and microbial biomass N, as well as lower rates of microbial respiration, mineralization and nitrification g(-1) SOM. Initial recovery of soil pools and processes appeared to be rapid, but additional research must be done to address the long-term rate of recovery in these forest stands. (C) 2004, Elsevier Ltd.
