Aquatic vascular plants of South Brazil: checklist and a comparative floristic approach Acta Botanica
Oliveira,Lukiel dos Santos; Andrade,Bianca Ott; Boldrini,Ilsi Iob; Moço,Maria Cecilia de Chiara.
ABSTRACT Aquatic ecosystems support species diversity, and knowledge of plant communities is essential for wetland conservation programs. This study provides a checklist of aquatic vascular plants of South Brazil and establishes their floristic affinities with bordering South America phytogeographical domains. The checklist was based on 52 sources, including 35 floristic lists, 17 regional taxonomic studies, and information from an electronic database on wetlands of South Brazil. Floristic similarities with published checklists for neighbouring regions were assessed. A total of 780 species distributed in 277 genera and 85 families of vascular plants were reported for South Brazil. Families with higher species richness were Cyperaceae (128), Poaceae (102),...

Atributos microbiológicos do solo como indicadores de conservação das pastagens nativas do Pantanal. Repositório Alice
PELISSARO, H. E. G.; ZANELLA, M. S.; SANTOS, S. A.; CARDOSO, E. L.; BRASIL, M. S..
O objetivo desse trabalho foi avaliar os atributos microbiológicos do solo sob pastagens nativas das áreas úmidas em diferentes estados de conservação no Pantanal da Nhecolândia. Foram selecionadas pastagens nativas de áreas úmidas com três diferentes estados de conservação (ótimo, regular e marginal) e coletadas amostras de solos para avaliação da produção de biomassa de plantas e atividade microbiana. Os diferentes estados de conservação das pastagens influenciaram a produção de biomassa e atividade microbiana, e as condições mais favoráveis para a microbiota do solo ocorreram no melhor estado de conservação. Os maiores teores de carbono da biomassa microbiana (Cmic) ocorreram nas pastagens nativas com cobertura vegetal superior a 80% (estado ótimo) e...

Distribution and conservation status of giant otter Pteronura brasiliensis in the Pantanal wetland, Brazil. Repositório Alice
TOMAS, W. M.; CAMILO, A.R.; RIBAS, C.; LEUCHTENBERGER, C; BORGES, P.A.L; MOURAO, G.; PELLEGRIN, L. A..
The giant otter (Pteronura brasiliensis) is listed as vulnerable in Brazil, is included in Appendix I of CITES and is classified as endangered by the IUCN. In Brazil, few viable populations persist outside the Amazon basin and the Pantanal wetland. Furthermore, there is limited information on the distribution and abundance of the existing populations. The aim of this study was to estimate the abundance of giant otters in the Pantanal wetland and to discuss the conservation status of this population. From July 2000 to November 2011 we conducted surveys throughout the Pantanal to detect the occurrence of giant otters by the observations of active dens and latrines and the direct visualization of the otters. We also monitored giant otter population in five...

From Satellite Imagery to Peatland Vegetation Diversity: How Reliable Are Habitat Maps? Ecology and Society
Rochefort, Line; ;.
Although satellite imagery is becoming a basic component of the work of ecologists and conservationists, its potential and reliability are still relatively unknown for a large number of ecosystems. Using Landsat 7/ETM+ (Enhanced Thematic Mapper Plus) data, we tested the accuracy of two types of supervised classifications for mapping 13 peatland habitats in southern Quebec, Canada. Before classifying peatland habitats, we applied a mask procedure that revealed 629 peatlands covering a total of 18,103 ha; 26% of them were larger than 20 ha. We applied both a simple maximum likelihood (ML) function and a weighted maximum likelihood (WML) function that took into account the proportion of each habitat class within each peatland when classifying the habitats on...

Sustainable livelihoods through conservation of wetland resources: a case of economic benefits from Ghodaghodi Lake, western Nepal Ecology and Society
Lamsal, Pramod; ; pramod_lamsal@yahoo.com; Pant, Krishna Prasad; Kathmandu University; Krishna.Pant@ku.edu.np; Kumar, Lalit; University of New England; lkumar@une.edu.au; Atreya, Kishor; Kathmandu University; k.atreya@gmail.com.
We investigated the participation of local ethnic groups in wetland conservation, determined the economic benefits that they received from the wetlands, and assessed socioeconomic factors that affect dependency on wetlands. A total of 217 wetland resource-user households residing around Ghodaghodi Lake, western Nepal were surveyed. Data were analyzed using descriptive statistics, t-tests and ordinary least squares regressions. The wetland resources contributed significantly to the household economy of the local people. Each household extracted lake resources at an annual worth of NPR 4379 ($63 USD), equivalent to 12.4% of the household total gross income. Although the people maintained a positive attitude toward wetland conservation, their participation in...
