Most of the previous records of the freshwater molluscs from the Kruger National Park date back prior to and up to 1966. On account of several droughts between 1966 and 1995 it was decided to do a survey of the freshwater mollusc population in 1995 to evaluate the effect of these droughts. The traditional mollusc intermediate hosts were also screened for trematode parasites to establish whether or not they were infected. No infected molluscs were found. Eight of the 19 species reported up to 1966 were not found during the 1995 survey. Three new mollusc species were collected in 1995. The consequences of the drought are clearly visible when the species diversity found in the dams in the 1995 survey, is compared to what was previously recorded.

Distribution Of Fish

We evaluated diversity and distribution of fish species in two habitats: flooded forest and open water of lakes of Rio Negro. Each of four lakes within the Anavilhanas Archipelago was sampled three times from 2009-2010. Species diversity generally was higher in flooded forests and at night, according to correspondence analysis. Predators were most active at night, but showed no preference between the flooded forest and open water habitats. Omnivores, filter feeders, and detritivores were most active during the day.

Study on plant community structure was undertaken in different altitudinal ranges of Shivapuri National Park. The general objective of this study is to analyse different plant community structure in Shivapuri National Park with regards to altitudinal variation. The forest was divided into three distinct altitudinal ranges on the basis of dominancy. In each altitudinal range standard quadrats method was applied for vegetation analysis. The highest number of species was found in site II. All the ecological parameters of the plant species were higher in site II except Basal Area of tree that was highest in site III. The pattern of distribution of plant species was not uniform according to altitude. At higher elevation, the forest was mature with almost closed canopy and trees were large; so the tree density was low. Species richness was highest in site II. Species diversity among tree and shrub species was higher in site I. But for herb species diversity was higher in site II for both seasons. Such type of variations may be due to nature of soil i.e. acidity, nutrient availability and other micro-climatic factors. The most noteworthy thing was that variation in flower colour of Rhododendron arboreum i.e. deep scarlet at low altitude, but it gradually changed into pinkish white as altitude increased.

Acacia decurrens, originally from Australia, is a woody plant that has become a concern in the erupted areas of Merapi volcano in 2006. The purpose of this study was to quantitatively describe the ecology of Acacia decurrens, and its invasive potential. Vegetation analysis was carried out in four areas of Mount Merapi National Park (TNGM), namely Kalikuning, Kaliadem, Plawangan and Pranajiwa. Ordination using the Non Metric Multidimensional Scaling (NMDS) method and Canonical Correspondence (CCA) and Spearman's bivariate correlation were carried out in data analysis. The results of NMDS analysis (2D stress = 0.14) showed that open areas due to eruption in Kaliadem are now dominated by A. decurrens. The results of the analysis also showed a significant negative correlation (Spearman rho = 0.6) between the abundance of A. decurrens and the level of species diversity in the sampling location. From the results of CCA, A. decurrens in the seedling stage appeared to coexist with other types of ground cover such as Alangium javanicum and Araliaceae. But in the tree phase, this species tended to form pure stands and only occasionally appeared to live side by side with other types of Fabaceae such as Albizia lopantha. Tree-level A. decurrens seemed to prefer sites with lower pH levels while A. decurrens seedling levels were more commonly found in sites with higher pH. Acacia decurrens have the potential to become a weed in TNGM due to its dominant distribution and tendency to decrease the level of species diversity in TNGM.

O Parque Nacional dos Campos Gerais (PNCG) detém áreas de campos de altitude sob forte pressão antrópica, com a expansão das atividades agrícolas, pecuária, silvicultura e visitação turística desordenada. Devido ao impacto gerado, existe uma tendência à diminuição da riqueza específica, através da seletividade de espécies. Este trabalho analisa a resposta das comunidades campestres em termos de composição de espécies aos impactos de pastejo, roçada e pisoteio humano. Em quatro estações de coleta, foram determinados 107 táxons distribuídos em 23 famílias botânicas. As famílias com maior riqueza específica foram Asteraceae e Poaceae, ambas com 24 táxons, e Fabaceae, com 14 táxons. A riqueza específica variou de 27 a 75 espécies, com maior riqueza na estação não pastejada nem roçada, apenas visitada por turistas. O levantamento mostrou que, apesar da pressão antrópica, as áreas estudadas exibem considerável riqueza específica quando comparadas a outros trabalhos na região, mantendo ainda seu potencial biótico dinâmico. Floristicamente, os impactos gerados por gado ou por manejo com roçadeira se equivalem. Seis gêneros têm potencial para serem utilizados como bioindicadores de áreas conservadas: Croton, Galactia, Periandra, Cuphea, Pavonia e Commelina, mas há necessidade de ampliação das áreas estudadas para estabelecer mais claramente seu valor de bioindicação.Palavras-chave: Campo nativo; Campos Gerais; área impactada; pastejo; visitação turística. AbstractThe species diversity in native grassland areas that are under impact of tourism and grazing at Campos Gerais National Park, Parana, Brazil. Campos Gerais National Park (PNCG) has areas of grassland under high anthropogenic pressure, as expansion of agricultural activities, livestock, forestry and disorderly tourism. Due to these impacts, there is a tendency to decrease local biodiversity by selection of more resistant species. This paper focuses the grassland community answers to mowing, grazing and tourism. In four sampling sites it was determined 107 taxa belonging to 23 botanic families. The main families are Asteraceae (24 taxa), Poaceae (24 taxa) and Fabaceae (14 taxa). Species diversity varied from 27 to 75 species. In relation to species number, non-grazed areas presented greater diversity than other ones; it points to that touristic visitation may cause lower impact than grazing or mowing. In spite of the anthropogenic factors, the focused sites presented high specific diversity in relation to related areas. In relation to species diversity, grazing or mowing are equal. Six genera presented potentiality as bioindicators of preserved environments: Croton, Galactia, Periandra, Cuphea, Pavonia, and Commelina, although more sample areas are necessary to reliable results.Keywords: Grasslands; Campos Gerais; impacted area; grazing; touristic activities.
