Abstract:
Geomorphological features and sedimentary characteristics are analized from five sets of shallow sediment cores collected in lakes in the Fildes Peninsula, King George Island. The geomorphology of the area was observed and sediments samples were obtained at field activities during the XXXI Brazilian Antarctic Operation (March-April/2013). Biogeochemical characteristics, physical parameters, mineralogical composition, particle size distribution, macroscopic characteristics of the sediments and satellite images were analized. Preliminary results indicate climatic and environmental changes in nor

Abstract:
Flooding of land associated with the creation of reservoirs may increase, at least in the short term, methane flux to the atmosphere. To evaluate the potential contribution of such land use on methane production, field samples were studied in vitro for the potential activity of methanogenic bacteria in unflooded or flooded boreal forest soils, together with lacustrine sediments. From this comparative study, periodically flooded or flooded peats contribute more to methane production than do unflooded peats, soils, and natural lake sediment. The intensity and temporal changes in the activity of

This text explains why the results of research carried out in the State of Acre in the years 2002 to 2008 were released late, with financial support from two research projects financed by the CNPQ (SelenMerAs and Geosedintama) and a third (Ageopam) which also had a slight facet towards the region of this State. Although several works were published through communications at events and journals, much was restricted to dozens of dissertations, TCCs and reports from IC/PIBIC and others. It was concluded that even after almost 20 years, it was still opportune to disseminate these results and discu

Abstract:
Hesperodiaptomus arcticus, a predatory calanoid copepod, was eliminated from two alpine lakes within 6 years of stocking with salmonids. Using historical and contemporary Zooplankton and fish data, sediment analysis for diapausing eggs, and experiments on predation of Gammarus lacustris on diapausing eggs of H. arcticus, we assess the fate of these populations 35 years after fish stocking. In Pipit Lake, in which the trout introduction failed within 21 years, we propose that H. arcticus recovered as a result of hatching of diapausing eggs held in the sediments.

Abstract:
Difficulties in producing a muddy substrate which does not easily foul have made previous efforts to culture mud-inhabiting, estuarine, and marine harpacticoid copepods unsuccessful. Natural, organic-rich muds are unsuitable as a long-term culture medium because they generate detrimental bacterial blooms in stagnant and periodically flushed culture systems. I present some simple procedures to (1) sort muddy sediments into a <125-μm size class, (2) flush away most dissolved organics, (3) sterilize the sediments providing a moderately foul-free culture medium, (4) generate a life-like, floccu
