13. Extreme morphologies of mantis shrimp larvae
ABSTRACT Larvae of stomatopods (mantis shrimps) are generally categorized into four larval types: antizoea, pseudozoea (both representing early larval stages), alima and erichthus (the latter two representing later larval stages). These categories, however, do not reflect the existing morphological diversity of stomatopod larvae, which is largely unstudied.

14. Report on the Malungo expedition to the Erepecuru river, Oriximiná, Brazil. Part I: is there a difference between black and white breu?
ABSTRACT Species belonging to Burseraceae produce an oleoresin known in the north of Brazil as breu. They comprise an essential oil with a complex composition, and are used in Amazonia for smoking the environment, to caulk boats and for medicinal purposes. Depending on its organoleptic characteristics and on the breu-producing species, they are called white

16. Perezone, from the gorgonian Pseudopterogorgia rigida, induces oxidative stress in human leukemia cells
Abstract Four bisabolanes 1–4, including perezone (1) and triacetyl perezone (2), were isolated through a bioassay-guided fractionation of the extract obtained from the Caribbean gorgonian coral Pseudopterogorgia rigida collected during an expedition cruise to the Bahamas. All isolated compounds showed to be cytotoxic toward panel of four human tumor cell

17. METODOLOGIAS DE COLETA, PRESERVAÇÃO E ARMAZENAMENTO DE AMOSTRAS DE ÁGUA PARA ANÁLISE DE MERCÚRIO - UMA REVISÃO
Knowing the mercury levels of an environment allows a diverse array of biogeochemical studies into the mercury cycle on a local or global scale. Among matrices commonly evaluated, water remains a challenge for research because its mercury levels can be very low, requiring development of complex analytical protocols. Currently, sample preservation methods, pr

18. O litoral do Nordeste do Brasil como objeto científico darwinista: as prospecções de John Casper Branner, 1899-1911
John Casper Branner, geólogo norte-americano, desenvolveu uma longa história de investigação no Brasil. Analisa-se, aqui, como ele tratou a geologia do litoral do Nordeste na Branner-Agassiz Expedition (1899) e na Stanford Expedition (1911). As expedições indicam como a geomorfologia das bacias sedimentares, dos recifes de arenito e dos recifes de cora

19. The Compact Irradiator Modulus Designed for DNA Repair and Mutagenesis Studies in ISS Microgravity Environment Using UVA Emitted by Light-Emitting Diodes
ABSTRACT: This work presents the design and characteristics of a new compact ultraviolet (UV) irradiator used in a biological onboard space flight experiment. The experiment, called DRM, took place in the International Space Station research facility (ISS-13 expedition), during the Centenary Mission (Russian-Brazil) in March-April 2006. The DRM main objectiv

20. Os objetivos da circunavegação da U.S. Exploring Expedition (1838-1842): longitude, mapeamento náutico e instituição das coordenadas geográficas modernas
Analisa o principal objetivo da viagem científica de circunavegação realizada pelos EUA entre 1838 e 1842. A tarefa de mapeamento destaca-se entre outras metas científico-estratégicas da viagem exploratória. A iniciativa da empreitada foi movida pela busca da exata localização em alto-mar após a instituição do sistema de longitudes, quando cartas

21. First Record of Culex (Culex) brethesi (Dyar) (Diptera: Culicidae) in Rio Grande do Sul State, Brazil
This is the first record of Culex (Culex) brethesi (Dyar) in Rio Grande do Sul state, Brazil. The species was identified from specimens collected in a sand bar vegetation with the aid of a Nasci's trap, during an expedition for surveillance of the West Nile Virus in July of 2006, in the city of Mostardas, Rio Grande do Sul, Brazil.

22. Collecting common bean (Phaseolus vulgaris L.) germplasm in southern Brazil.
This expedition was organized to explore regional common bean types and to obtain a representative collection of landraces farmed in Southern Brazil. Emphasis was also given to the collecting of some ethnic, botanical and economical information and to determine the extent of genetic erosion in the region.
