Building bridges between environmental and political agendas is essential nowadays in face of the increasing human pressure on natural environments, including wetlands. Wetlands provide critical ecosystem services for humanity can generate a considerable direct or indirect income to local communities. To meet many sustainable development goals, we need move our trajectory from current destructive wiser wetland use. The article contain proposed agenda Pantanal aiming improvement public policy...
This study evaluated the feasibility of using Ribulose Bisphosphate Carboxylase Large subunit gene (rbcL) and Internal Transcribed Spacers 1 2 nuclear rDNA (nuITS1 nuITS2) markers for identifying a very diverse, albeit poorly known group, green microalgae from neotropical inland waters. Fifty-one freshwater strains isolated Brazil, largest biodiversity reservoir in neotropics, were submitted to DNA barcoding. Currently available universal primers ITS1-5.8S-ITS2 region amplification...
Limnoperna fortunei (Dunker, 1857) is a small mytilid native to Southeast Asia. It was introduced in South America early 1990 and has dispersed from Argentina central Brazil, until 2014 been restricted mainly the Paraná Uruguay river basins. The present note reports occurrence of for first time São Francisco River basin northeastern Brazil. establishment L. these regions will require close attention government also by society.
Este trabalho de conclusão curso aborda a importância da assistência humanizada nos cuidados paliativos, explorando como prática humanizadora é essencial para proporcionar qualidade vida e conforto pacientes em estágios avançados doenças incuráveis. A humanização nesses busca atender às necessidades emocionais, psicológicas sociais dos pacientes, respeitando sua dignidade individualidade, enquanto acolhe também as famílias que enfrentam o processo fim vida. metodologia empregada baseia-se...
Adaptation is an essential step in the establishment and spread of alien species new environments, with phenotypic plasticity or genetic variability often contributing to this success. The golden mussel Limnoperna fortunei a biofouling mollusc native Southeast Asia that was introduced South America near Río de la Plata estuary, Argentina, though has subsequently more than 2000 km upstream. We analyzed morphological variation 24 populations L. across its American range. Relative gill area...
Small hydropower (SHP) facilities, are commonly being built around the world. SHPs viewed as less environmentally harmful than larger dams, although there has been little research to support that assertion. Numerous have built, and many more in development or proposed, rivers drain into Pantanal, a world-renowned floodplain wetland. Three river systems with largest contributions of sediments Pantanal—the Cuiabá, upper Taquari, Coxim rivers—remain largely undammed. The upland tributaries...
The seasonal variability of the phytoplanktonic community was studied in one lateral channel Upper Parana River. extensive samplings (monthly) were taken three stations Cortado Channel (22o47‘30”S, 53o24‘37”W) from March 1993 to February 1994. Temporal changes taxonomic composition, density, biomass, diversity and dominance analyzed relation regional climate hydrology, physical chemical factors water column. composed 95 taxa. classes Cyanophyceae ( Anabaena circinalis ) Bacillariophyceae...
ABSTRACT In the upper Paraguay River basin, which includes Pantanal, one of largest wetlands in world, rivers connection surrounding upland plateaus with lowland floodplains. Agriculture, erosion, urban effluent, and hydropower uplands can alter transport materials by to Pantanal. Information about material transport, particularly nutrients, is still insufficient evaluate changes. this study we estimated rates dissolved suspended from watersheds into through River, calculated mass balances...
Small hydropower (SHP) facilities, defined variably but usually by installed capacities of <10–50 MW, are proliferating around the world, particularly in tropical and subtropical regions. Compared to larger dams, SHPs generally viewed as having less environmental impact, although there has been little research support that assertion. Numerous have built, many more development or proposed, rivers drain into Pantanal, a world-renowned floodplain wetland system located mostly Brazil. The...
AIM: The present study involved an analysis of the monthly variations in population densities and body sizes different stages planktonic larvae invasive golden mussel (Limnoperna fortunei), rivers Paraguay Miranda; METHODS: was carried out between February 2004 January 2005. Monthly collection plankton samples accompanied by physical, chemical biological analyses water; RESULTS: Miranda River presented higher values calcium, pH, alkalinity, conductivity total phosphorous. Larval density...
Abstract Cage fish farming is an important economic activity in Brazil where tilapia ( Oreochromis niloticus ) the main cultivated species. To investigate cage farm as a vector for golden mussel invasion, we hypothesised that: (1) Limnoperna fortunei , freshwater bivalve mollusc, finds greater food availability farm; (2) favours mollusc colonisation and its nutritional status; (3) performance reservoir would vary over year. We obtained data from limnological variables well number of larvae...
O mexilhão dourado ou Limnoperna fortunei é um organismo invasor que tem causado grandes prejuízos a sistemas de captação água e usinas hidroelétricas, sendo que, mais recentemente, vem causando danos ao deslocamento embarcações fluviais em águas do Pantanal Mato-Grossense. No presente trabalho, foi feito estudo, laboratório campo, materiais antiincrustantes. A relação entre força desligamento energia livre superfície avaliada. Foram selecionados com baixa como polímeros alta metálicos....
Com a finalidade de avaliar colonização um substrato artificial por macroinvertebrados límnicos, foram realizados experimentos em duas estações coleta no delta do rio Jacuí, Porto Alegre (RS, Brasil): Canal Jacuí (CJ) e Cais (PO). Os substratos constituídos garrafa PET com uma malha interna nylon. organismos que apresentaram os maiores valores densidade média exposto CJ L. fortunei (8229,0ind.m-2), Chironomidae (188,9ind.m-2) Heleobia piscium (39,6ind.m-2) PO, (3233,0ind.m-2), (288,9ind.m-2)...
