Última Estimating the snake species richness of the Santubong Peninsula (Borneo) in two different ways Naturalis Rooijen, J. van. The distribution of Borneo’s species across the island is far from well-known. This is particularly true for snakes which are hard to find. Given the current rate of habitat destruction and consequent need for conservation strategies, more information is required as to the species composition and richness of specific areas of potential conservation priority. An example is the Santubong Peninsula, Sarawak, Malaysia, part of which has recently been gazetted as a National Park. In this paper, the snake species richness of the Santubong Peninsula is estimated on the basis of data obtained during 450 survey-hours. Thirty-two species were recorded. Negative exponential and Weibull functions were fitted to the rarefaction curve. The Weibull function exhibited a...

Ano: 2009 URL: http://www.repository.naturalis.nl/record/320292 Effects of different temperatures on the performance of seeds germination of Cecropia pachystachya Trec. (Cecropiaceae) BABT Pilati,Rosemari; Andrian,Izabel de Fátima; Carneiro,José W. P.. Seed germination of Cecropia pachystachya Trec. was investigated at 25, 30, and 35ºC using fluorescent day lights. Ten replicates each of 200 seeds were used in each thermal treatment. Germitest® paper, CEL-065®, and 11x11x5 cm Gerbox® were also used. The frequencies of radicle protrusions were counted at consecutive two hour intervals. The cumulative frequencies were combined with the distribution of Weibull using the following model: Y = M (1 - exp (-(t/b)c)). The best performance was achieved with the temperature of 30ºC ( M, 95.29%). Time to achieve 60.23% of seed germination (0.6321 x 95.29%) was 99.35 h with a spread of 7.19. All model/data set combinations had close to linear. Tipo: Info:eu-repo/semantics/article Palavras-chave: Cecropia pachystachya; Seed germination; Weibull function.
