An��lise estrutural em relictos de cerrado no parque estadual do Guartel��, munic��pio de Tibagi, estado do Paran��, Brasil

This study was accomplished in existing Cerrado's relicts at State Park Guartel��, Tibagi, PR (24��39'10S and 50��15'25W), which represent one of the last extreme-meridional remanescents of this type of formation. Fifty plots with dimensions of 5x5m were allocated for phyto-sociological analysis, including in the sample individuals with height ��� 1 m, divided into two samples to evaluate the following strata: a) upper-plants with DAS ��� 3 cm, and b) intermediate - plants with DAS <3cm. Moreover, in each plot, there were established sub-plots with dimensions of 1x1m for sampling the lower stratum, comprised by individuals with height <1m and >10cm. The complete survey found 1340 individuals distributed in 28 families, 66 genera and 115 species. The diversity index was higher for the mean component (H'=3.30), followed by the superior component (H'=3.09) and the inferior (H'=2.91). The frequent occurrence of bushes is a remarkable characteristic of the physiognomy of the areas inside the park and 82 % of the populations studied are distributed in aggregated standard. Because it is a marginal region of occurrence of cerrado vegetation, now under the influence of a subtropical climate, more humid and cold, compared to the core area of this biome, it is noted that these areas are characterized by a decrease in stature, richness and diversity of its flora. Nevertheless, they preserve typical species of the Brazilian Savannah; but, due to their distribution in relicts and been, in part, devastated, some are included in the red list of endangered plants in Parana state, which evidences the importance of conservation and management of these areas.

Caracteriza����o morfol��gica, perfil qu��mico, atividade biol��gica e conserva����o in situ do g��nero Lychnophora Mart. (Asteraceae: Vernonieae: Lychnophorinae), Brasil

Many people who live in the cerrado regions use plant species for therapeutic purposes. However, due to intensive extraction of some species, native botanical populations are at risk of disappearing or suffering a dramatic decrease, such as, for instance, individuals of the Lychnophora genus. This has 24 species distributed into the categories vulnerable, endangered, critically endangered, and possibly extinct. These individuals are known in folk medicine as ���arnica��� and their leaves and flowers are commonly used as anti-inflammatory, analgesic, and healing agents. The chemical profile of the genus is characterized by the presence of sesquiterpene lactones, sesquiterpenes, diterpenes, triterpenes, flavonoids, steroids, polyacetylenes, and caryophyllene derivatives which also have lignans with analgesic activity. Studies with Lychnophora species show significant results with regard to their biological activities against Leishmania amazonensis, Staphylococcus aureus, and Tripanosoma cruzi. Therefore, this study aimed to perform a survey of the morphology, chemical composition, and biological activity, as well as the use and current conservation status of the Lychnophora genus in Brazil.

Wildlife Tuberculosis in South African Conservation Areas: Implications and Challenges

Tuberculosis, caused by Mycobacterium bovis, was first diagnosed in African buffalo in South Africa���s Kruger National Park in 1990. Over the past 15 years the disease has spread northwards leaving only the most northern buffalo herds unaffected. Evidence suggests that 10 other small and large mammalian species, including large predators, are spillover hosts. Wildlife tuberculosis has also been diagnosed in several adjacent private game reserves and in the Hluhluwe-iMfolozi Park, the third largest game reserve in South Africa. The tuberculosis epidemic has a number of implications, for which the full effect of some might only be seen in the long-term. Potential negative long-term effects on the population dynamics of certain social animal species and the direct threat for the survival of endangered species pose particular problems for wildlife conservationists. On the other hand, the risk of spillover infection to neighboring communal cattle raises concerns about human health at the wildlife���livestock���human interface, not only along the western boundary of Kruger National Park, but also with regards to the joint development of the Greater Limpopo Transfrontier Conservation Area with Zimbabwe and Mozambique. From an economic point of view, wildlife tuberculosis has resulted in national and international trade restrictions for affected species. The lack of diagnostic tools for most species and the absence of an effective vaccine make it currently impossible to contain and control this disease within an infected free-ranging ecosystem. Veterinary researchers and policy-makers have recognized the need to intensify research on this disease and the need to develop tools for control, initially targeting buffalo and lion.
