Information on the biology and populations of the shortnose sturgeon, Acipenser brevirostrum, is compiled, reviewed, and analyzed in the FAO species synopsis style. New information indicates this species exhibits biological and life-cycle differences over its north-south latitudinal range and that it is more abundant than previously thought.

The Johnny Lyon Hills area is located in Cochise County in southeastern Arizona. The rocks of the area include a central core of Lower pre-Cambrian igneous and metamorphic rocks surrounded by a complexly faulted and tilted section of Upper pre-Cambrian and Paleozoic strata. Limited exposures of Mesozoic and Tertiary sedimentary and volcanic rocks are present at the north end of the map area. Late Tertiary and Quaternary alluvium almost completely surrounds and overlaps upon the older rocks.

The older pre-Cambrian rocks include a section of more than 9000 feet of generally moderately metamorphosed graywackes, slates and conglomerates of the Pinal schist injected in zones by somewhat younger rnyolite sheets. The original sediments were deposited in a geosyncline whose extent probably included large parts of Arizona, New Mexico and west Texas. During the Mazatzal Revolution the Pinal schist was deformed into northeast-trending, steeply dipping and plunging structures and the entire local section was overturned steeply toward the northwest. The pre-Cambrian Johnny Lyon granodiorite was emplaced as a large epi-tectonic pluton which modified the metamorphic character of part of the Pinal schist. Larsen method determinations indicate an age of about 715 million years for this rock, which is about the minimum age compatible with the geologic relations.

The Laramide orogeny produced numerous major thrust faults in the area involving all rocks older than and including the Lower Cretaceous Bisbee group. Major compression from the southwest and subsequent superimposed thrusting from the southeast and east are indicated. Minimum thrust displacements of more than a mile are clear and the probable displacements are of much greater magnitude. The crystalline core behaved as a single structural unit and probably caused important local divergences from the regional pattern of northeast-trending compressive forces. The massif was rotated as a unit 40 degrees or more about a northwest-trending axis overturning the pre-Cambrian fold axes in the Pinal schist.

Swarms of Late Cretaceous(?) or Early Tertiary(?) lamprophyric dikes cross the Laramide structures and are probably related to the large Texas Canyon stock several miles southeast of the map area. Intermittent high angle faulting, both older and younger than the dikes, has continued since the Laramide orogeny and has been superimposed on the older structures. This steep faulting combined with the fundamental northwesterly Laramide structural grain to produce the northwesterly trends characteristic of the mountain ridges and valleys of the area.

O museu como instituição de produção, guarda e difusão de conhecimentos necessita criar e desenvolver estratégias que se encontram articuladas a demandas sociais de um determinado tempo histórico, assim como àquelas que lhes são próprias. O estudo das ações educativas desenvolvidas pelo Museu Nacional do Rio de Janeiro no período entre sua criação em 1818 e a década de 1930 com os objetivos de divulgar o conhecimento científico por ele produzido e apoiar o ensino das ciências naturais é objeto deste trabalho, na tentativa de compreendê-las enredadas no contexto mais amplo de institucionalização da educação, racionalização da pedagogia, formação do caráter público dos museus e construção da nação brasileira. Operando com as continuidades e descontinuidades dessas ações no período proposto, a pesquisa foi desenvolvida através da investigação de um conjunto documental, composto dos seguintes tipos: a) legislação brasileira, pertinente à educação e ao Museu Nacional; b) correspondência efetivada entre o Museu, ministérios, instituições e autoridades; c) relatórios de Diretores, Secretário, pesquisadores do Museu Nacional; dos ministérios; de naturalistas e professores; d) livros de registros do Museu Nacional; e) catálogos, programas e guias de exposições nacionais e internacionais; f) publicações de diretores do Museu Nacional e de professores; g) conferências sobre ciência e educação; h) periódicos; i) quadros murais e coleções didáticas. Desse conjunto tratamos em especial os materiais que serviram de suporte e veículo de comunicação, com a pretensão de evidenciar o museu como espaço educativo, valorizando suas ações dirigidas para a instrução pública. De acordo com os resultados obtidos, foi possível observar que ao longo do Império e nas quatro primeiras décadas da República no Brasil o Museu Nacional atuou como agência de consultoria de governo, ampliando suas ações educativas para atender às necessidades de diferentes segmentos da sociedade e às suas demandas internas. Nesse sentido, contribuiu para afirmar estudos em História Natural apoiados na teoria evolucionista; inserir o Brasil no cenário científico internacional; instruir e ampliar os conhecimentos sobre o país, valorizando suas riquezas naturais, estimulando no público, especialmente o escolar, o caráter prático do ensino e um sentimento de pertencimento e de identidade nacional.

The jinjiang oyster Crassostrea rivularis [Gould, 1861. Descriptions of Shells collected in the North Pacific Exploring Expedition under Captains Ringgold and Rodgers. Proc. Boston Soc. Nat. Hist. 8 (April) 33-40] is one of the most important and best-known oysters in China. Based on the color of its flesh, two forms of C rivularis are recognized and referred to as the "white meat" and 11 red meat" oysters. The classification of white and red forms of this species has been a subject of confusion and debate in China. To clarify the taxonomic status of the two forms of C. rivularis, we collected and analyzed oysters from five locations along China's coast using both morphological characters and DNA sequences from mitochondrial 16S rRNA and cytochrome oxidase 1, and the nuclear 28S rRNA genes. Oysters were classified as white or red forms according to their morphological characteristics and then subjected to DNA sequencing. Both morphological and DNA sequence data suggest that the red and white oysters are two separate species. Phylogenetic analysis of DNA sequences obtained in this study and existing sequences of reference species show that the red oyster is the same species as C. ariakensis Wakiya [1929. Japanese food oysters. Jpn. J. Zool. 2, 359-367.], albeit the red oysters from north and south China are genetically distinctive. The white oyster is the same species as a newly described species from Hong Kong, C. hongkongensis Lam and Morton [2003. Mitochondrial DNA and identification of a new species of Crassostrea (Bivalvia: Ostreidae) cultured for centuries in the Pearl River Delta, Hong Kong, China. Aqua. 228, 1-13]. Although the name C. rivularis has seniority over C. ariakensis and C. hongkongensis, the original description of Ostrea rivularis by Gould [1861] does not fit shell characteristics of either the red or the white oysters. We propose that the name of C. rivularis Gould [1861] should be suspended, the red oyster should take the name C. ariakensis, and the white oyster should take the name C. hongkongensis.
