Os crustáceos anomuros do gênero Aegla Leach (1820) são animais bentônicos característicos das águas continentais da América do Sul. Podem ser encontrados em arroios e rios de correnteza, ocultos sob pedras e detritos vegetais. Foram descritas 61 espécies desse gênero, que se encontram distribuídas pela região Neotropical com limites norte no município de Franca, no Estado de São Paulo, Brasil e sul na Ilha de Madre de Diós, na Província de Última Esperanza, Chile. Esses animais são considerados importantes elos nas cadeias alimentares dos ambientes líminicos, atuando como predadores de larvas aquáticas de insetos e são presas de aves, rãs, jacarés e peixes. Podem também ser utilizados como bioindicadores na avaliação de qualidade das águas onde ocorrem, uma vez que são bastante sensíveis a mudanças do ambiente. Apesar do expressivo número de espécies do gênero Aegla descritas, existem poucos estudos sobre sua dinâmica populacional, especialmente no que diz respeito a análises enfocando crescimento relativo. O objetivo deste trabalho foi caracterizar o crescimento relativo da espécie Aegla castro no município de Itatinga, interior do Estado de São Paulo. Os eglídeos foram coletados mensalmente durante um ano (Mar/07 a Fev/08) no município de Itatinga. Os animais amostrados foram obtidos mediante esforço de coleta e armadilhas. Para o primeiro método, os exemplares foram coletados com puçás ou peneiras posicionados próximos a pedras e seixos, os quais foram removidos manualmente para desalojar os animais que porventura estejam ali abrigados. No segundo método, foram instaladas armadilhas iscadas no final do período da tarde e recolhidas na manhã do dia seguinte. Os exemplares capturados tiveram os sexos determinados com base em caracteres sexuais secundários (posição da abertura do par de gonóporos... (Resumo completo, clicar acesso eletrônico abaixo)

The towns of Castro Alves and Rafael Jambeiro, central-east of Bahia state, are located in the east of São Francisco Craton, in granulite terrains of Salvador-Curaçá Belt, formed in Paleoproterozoic. The region of study contains ortognaisses of Caraíba Complex, metamafic and metaultramafic rocks of São José do Jacuípe Suite, metasedimentary rocks of Tanque Novo-Ipirá Complex, granitoids, pegmatites and alkaline rocks. The study carried out regional and detailed geological mapping in addition to petrographical and geochemical characterization of six areas in the search for targets of feldspar and white diopside, minerals used in ceramic industry. The areas consist of granitic ortognaisses interspersed with lenses of mafic granulite rocks, calc-silicate rock, banded iron formations, paragnaisses, quartzites, and bodies of quartz-feldspar or feldspar pegmatites and alkaline rocks that fill discontinuities. The region of study contains four deformations phases, with a predominance of ductile structures. The foliation Sn has N30E to N70W direction, high angle of dip and is characterized by compositional banding of granoblastic and felsic bands interspersed with nematoblastic or lepidoblastic mafic bands. A mineral or stretching lineation Ln is associated with Sn and has trend of S55E to S72E. The rocks have been suffered a regional metamorphism with granulite facies peak and partial retrogression to greenschist facies. Geochemical studies indicate that the green coloring calc-silicate rocks have lower SiO2, MgO and higher Fe2O3 content compared with white calcssilicate rocks. The alkaline rocks of the studied area have higher Na2O, SiO2 and lower K2O, Fe2O3 content compared with others Paleoproterozoic alkaline rocks of Bahia state. The targets of diopside are associated with white calc-silicate rocks, while the targets of feldspar are associated with paragnaisses, pegmatites and alkaline rocks

The Juanita H. Neely Papers consist of correspondence, autobiographical and biographical data, speeches, radio talks, clippings, photographs, and articles mainly relating to her work with the South Carolina Home Demonstration Extension Service. There is also family history material relating to the Neely family. This collection is a good source of information concerning the South Carolina Home Economics Extension program in the first half of the twentieth century. While the papers range from 1911 to about 1970, the more valuable and greater part of the collection extends from the mid-1920s to 1957, when Juanita Neely rose from a county home economics extension agent to the State Demonstration Agent. The collection contains many of her speeches, radio talks and articles made during this period; the reference material that she used for her speeches; letters of appreciation from agents and others upon her retirement; and materials relating to the Winthrop-Clemson controversy in 1955 concerning the location of the Home Economics Extension Program. There is also biographical material, award notices, and some correspondence dating after Juanita Neely's retirement from the Home Economics Extension Program. Additional Neely information may be found by referring to the Winthrop Archives, record group 412, and the 1958-1959 edition of Who’s Who of American Women.

The feeding ecology of Merluccius hubbsi was investigated in 2 regions of SE Brazil. The major food sources for the hakes were fish, crustaceans, and squid. In the upwelling system of Cabo Frio, the diet was very similar in the summers of 2001/2002 and spring 2002; fish were the most important prey followed by crustaceans. In Ubatuba, euphausiids were an important prey during the winter 2001 (100 m), while in the summer 2002, fish and amphipods predominated in the diet in the shallower site (40 m) and squid in the deeper site (100 m). The hakes showed temporal differences in stable isotope signatures in both regions, while C:N ratios varied only in Cabo Frio. delta(15)N and delta(13)C (bulk and corrected for lipid content) increased with fish length, which seems to be related to the increasing importance of fish and decreasing importance of euphausiids and amphipods in the diet of larger hakes. The mean trophic level of 3.7 for M. hubbsi was estimated using delta(15)N of bivalves as baseline and the fractionation of 3.4aEuro degrees between trophic levels.

The Neotropical genus Neodischistus Painter has a distribution restricted to South (Brazil and Argentina) and Central America (Panama). The genus is composed of two previously described species that are herein revised: N. currani Painter and N. collaris Painter. One new Brazilian species is described: N. marstoni sp. nov. Illustrations of the external morphology of adults and male and female terminalia are also included. An identification key to the species is presented and a short discussion about species distributions is added.
