Crescimento de Aegla jarai Bond-Buckup & Buckup (Crustacea, Anomura, Aeglidae)

Abstract: The growth of Aegla jarai was examined aiming to contribute with information about the bioecological profile of the species. The sampling was carried out at the Espingarda River system situated at the Parque Nacional da Serra do Itajai, Santa Catarina State, Brazil from July 2001 to September 2002. The sex and the length of cephalothorax (mm) were recorded and the specimens were brought back to the stream. The von Bertalanffy’s model was used to estimate growth based on the modal progression of the size, which resulted in the growth curves described by Lt = 25.11 [1- e – 0.0082 (t + 29.02)] (for the males) and Lt = 23.33 [1- e – 0.0048 (t + 46.45)] (for the females). The curves based on the means were also obtained which were Lt = 23.56 [1- e – 0.0101 (t + 19] (for the males) and Lt = 22.69 [1- e – 0.0052 (t + 40.95)] (for the females). The recruitment period extended throughout spring (October, November and December) and early summer (January). In the population of A. jarai the males attained larger sizes and a higher growth rate than females. The estimated longevity was two years for both sexes.

Productive performance of lettuce at different amounts and times of decomposition of dry scarlet starglory

Abstract: The use of spontaneous species as green manure in the production of vegetables is slowly starting to produce satisfactory results. The purpose of the present study was to evaluate the productive performance of lettuce at different quantities and times of decomposition of dry scarlet starglory (Merremia aegyptia L.) incorporated into the soil. The present study was carried out from October to December 2006 in a vegetable garden of Plant Sciences Department of the Universidade Federal Rural do Semi-Arido (UFERSA), Mossoro-RN¸ Brazil. The experimental design was a randomized complete block with the treatments arranged in a factorial 4 x 4 + 1, with three replications. The treatments consisted of the combination of four dry scarlet starglory amounts incorporated into the soil (2.6; 5.2; 7.8 and 10.4 t ha-1 of dry matter) with four different decomposition times (0; 10; 20 and 30 days before transplanting of lettuce - DBT), plus one additional treatment (80 t ha-1 of cattle manure, a traditional treatment in the lettuce cropping). The lettuce cultivar grown was 'Baba de Verao'. The evaluated characteristics were: height and diameter of plants, number of leaves per plant, fresh and dry mass of the lettuce shoots. The incorporation of dry scarlet starglory into the soil influenced the productive performance of lettuce in a positive way, thereby showing promise for use as a green manure. The highest fresh mass amount of the lettuce (15.33 t ha-1) was obtained with the incorporation of 6.68 t ha-1 of dry scarlet starglory to the ground in time of 30 days before transplanting of the lettuce.

Corals and calcified hydroids of the Manuel Luiz Marine State Park (State of Maranhão, Northeast Brazil)

Abstract: Amaral, F.D., Hudson, M.M., Steiner, A.Q. & Ramos, C.A.C. Corals and calcified hydroids of the Manuel Luiz Marine State Park (State of Maranhao, Northeast Brazil). Biota Neotrop. Sep/Dez 2007 vol. 7, no. 3 http://www.biotaneotropica.org.br/v7n3/en/abstract?article+bn00907032007. ISSN 1676-0603. This study aimed to collect information on the diversity of corals and calcified hydroids of the Manuel Luiz Marine State Park (state of Maranhao, Northeast Brazil) to aid in the development of a management plan for the park. A total of 21 cnidarian species were identified, of which 16 were corals and calcified hydroids. The bathymetric and geographic distribution of each of these species was extended. This area has a rich coral fauna in relation to other parts of Brazil and is comparable in diversity to the Abrolhos Islands (Bahia State) - an unexpected result considering the region's proximity to the Amazon River Basin. Most of the specimens of corals and calcified hydroids observed were bleached.

Governança ambiental no Brasil: rumo aos objetivos do desenvolvimento sustentável (ODS)?

Abstract: Environmental governance is key to achieving the United Nations 2030 Agenda. This article explores Brazil's potential to address the 2030 Agenda Sustainable Development Goals. To do so, it presents Brazil’s advances and setbacks, particularly after the 1988 Federal Constitution, focusing on: environmental licensing, native vegetation, fishing resources, water resources, protected areas and climate change. We conclude the article by pointing out that the setbacks imposed on the environmental governance system over the last decade, and especially in the last year, indicate that the country is moving in a direction opposite to that of the future envisaged by Agenda 2030.
