Approximately 400 orchid species, distributed in 120 genera, are found in the RS state, Brazil. The highest concentration of orchids are in the eastern part of the state in the moist, mountainous Araucaria Forest, part of the Atlantic Forest. The CPCN-Pró-Mata is located within this region and has a climate which favours the growth of epiphytic pla...

The vitality of 64 lichen species (107 individual lichen thalli) growing under different light climates in an Araucaria forest in South Brazil was analyzed by chlorophyll fluorescence. Study sites were grouped according to their local light availability under full sunlight (about 2200 µmol m-2 s-1): 1 = low light, up to 20 µmol m-2 s-1; 2 = medium...

ResumoAfogamento é uma causa muito comum de morte em países como o Brasil, que possuem um extenso manancial hídrico. No entanto, o diagnóstico de morte por afogamento é considerado um dos mais difíceis da ciência forense, pois os sinais comuns utilizados na autópsia podem não estar presentes ou desaparecem rapidamente. Assim, o diagnóstico através...

NECLIME is an open international network of scientists working on Cenozoic climate evolution and related changes of continental ecosystems. During the past 65 million years of Earth history, globally warmer-then-present conditions prevailed in a world with almost modern paleogeography. These timespans represent promising case studies for anticipated future scenarios. Within the NECLIME network, we aim to combine data on past climate change and its environmental impact for large-scale reconstructions. NECLIME research activities comprise paleoclimate reconstructions, including atmospheric CO₂ and ecosystem analysis using multiple quantitative methods on various primarily continental proxies (plants; vertebrates; invertebrates; geochemistry and geological proxies). Complementing model studies are employed to assess connections and processes driving ocean, atmosphere and biosphere at global and regional scales. NECLIME was established in 1999 with the aim to understand Neogene trends across Eurasia. This basic idea quickly and constantly expanded to a global interest and a wider stratigaphical frame. The steadily growing NECLIME network with currently around 140 members in 34 countries is coordinated by a team of researchers and an advisory board. NECLIME holds annual conferences and workshops and administers working groups bringing forward scientific exchange, joint projects, and the integration of research data.
