Microhabitat de Tolypothrix distorta Kütz. ex Bornet & Flahault (Microchaetaceae, Cyanophyta) em dois riachos da região Centro-Sul do Estado do Paraná, Brasil

This study aimed to evaluate some microhabitat characteristics of two populations of Tolypothrix distorta in streams from midsouthern region of Paraná State on a seasonal period. Each population was monthly investigated for the abundance of T. distorta and environmental variables such as depth, current velocity, irradiance, richness, and substrate diversity (H') using the quadrat technique for each sample unit (n = 7-10). For each segment the following physical and chemical water variables were also measured: temperature, oxygen saturation, specific conductance, pH, and turbidity. The seasonal period of higher abundance (percent cover) occurred during the months corresponding to summer/fall for both populations. The analyses also showed that populations had lower niche width and wide variation under the environmental conditions, characterizing the species as a generalist in the use of resources. Faster water flow and larger substrates favored the development of T. distorta, which may be related to the species morphological characteristics, thallus type that consists of tangled filaments formed by tuft and covered with thick gelatinous coats.

Levantamento rápido de mamíferos terrestres de médio e grande porte no Parque Natural Municipal Cachoeira da Marta, Botucatu/SP

One of the most important strategies for biodiversity conservation is the establishment of protected areas, which protect areas important for the survival of several species. The park “Parque Natural Municipal Cachoeira da Marta”, located in Botucatu, São Paulo, is a unit of strictly protected area and aims to conserve the ecosystems and the biodiversity that exists in the area. The park has a management plan, but this does not include a survey of mammals present in the area, which is relevant as the group has a high degree of threat and a huge ecological importance. Thus, this study aimed to conduct a quick survey of terrestrial mammals of medium and large through the methodology of sand plots, with 25 plots distributed in five areas throughout the park. We recorded 4 orders, 6 families and 9 species (Nasua Nasua, Eira Barbara, Procyon cancrivorous, Leopardus pardalis, Leopardus sp., Dasypus novemcinctus, Tamandua tetradctyla, and Cavia aperea Myrmecophaga tridactyla). Most animals marked are generalist feeding habits, but it was also reported the presence of species more demanding regarding the quality of the habitat

Levantamento da mastofauna terrestre de médio e grande porte em três fragmentos de mata na Fazenda Experimental Lageado - Botucatu, SP

The present study aimed to survey the medium and large land mammals in three fragments at the Fazenda Experimental Lageado - UNESP/Botucatu, through the method of sand plots. 48 plots were used in total, 16 on each track. The paw prints found were photographed and identified from specific guides. 12 different species of mammals were found, these, 7 were classified at the level of species belonging to 9 families and 6 orders. The most representative order was Carnivora. Most of the species found have a generalist or omnivore habit, which can be related with the degree of the forest fragmentation. The only fragment of natural forest (semideciduous), presented the fewer numbers of species, which can be explained due to its isolation. The other fragment, which has near highway and other large fragment (Fazenda Experimental Edgárdia) was the most representative fragment, demonstrating the importance of nearest fragments to the continuity and survival of medium and large mammals
