Distribuição geográfica da fauna e flora da Baía de Guanabara

The author studied, the horizontal and vertical distribution of most common part of the flora and fauna of the bay of Guanabara at Rio de Janeiro. In this paper the eulittoral, poly, meso and oligohaline regions were localised and studied; and the first chart of its distribution was presented (fig. 2). The salinity of superficial waters was established through determinations based on 30 trips inside the buy for collecting biological materials. Some often 409 determinations which were previous reported together with the present ones served for the eleboration of a salinity map of the bay of Guanabara (fig. 1). This map of fig. 2 shows the geographic locations of the water regions. EULITTORAL WATER REGIME — Fig. 3 shows the diagram scheme of fauna and flora of this regime. Sea water salinity 34/1.000, density mean 1.027, transparent greenish waters, sea coast with moderate bursting waves. Limpid sea shore with white sand, gneiss with the big barnacle Tetraclita squamosa var. stalactifera (Lam. Pilsbry. Vertical distributions: barna¬cles layers with a green region in which are present the oyster Ostrea pa-rasitica L., the barnacles Tetraclita, Chthamalus, Balanus tintinnabulum var. tintinnabulum (L.) e var. antillensis Pilsbry in connection with several mollusca and the sea beatle Isopoda Lygia sp. Covered by water and exposed to air by the tidal ritms, there is a stratum of brown animals that is the layer of mussels Mytilus perna L., with others brown and chestnut animals : the Crustacea Pachygrapsus, the little crab Porcellana sp., the stone crab Me-nippe nodifrons Stimpson, the sea stars Echinaster brasiliensis (Mull. & Tr.), Astropecten sp. and the sea anemones Actinia sp. Underneath and never visible there is a subtidal region with green tubular algae of genus Codium and amidst its bunches the sea urchin Lycthchinus variegatus (Agass.) walks and more deeply there are numerous sand-dollars Encope emarginata (Leske). The microplancton of this regime is Ceratiumplancton. POLYHALINE WATER REGIMB — Water almost sea water, but directly influenced by continental lands, with rock salts dissolved and in suspension. Salinity: 33 to 32/1.000. This waters endure the actions of the popular nicknamed «water of the hill» (as the waters of mesohaline and oligohaline regimes), becoming suddenly reddish during several hours. That pheno¬menon returns several times in the year and come with great mortality of fishes. In these waters, according to Dr. J. G. FARIA there are species of Protozoa : Peridinea, the Glenoidinium trochoideum St., followed by its satellites which he thinks that they are able to secret toxical substances which can slaughter some species of fishes. In these «waters of the hill» was found a species of Copepoda the Charlesia darwini. In August 1946 the west shore of the Guanabara was plenty of killed fishes occupying a area of 8 feet large by 3 nautical miles of lenght. The enclosure for catching fishes in the rivers mouthes presents in these periods mass dead fishes. The phenomenon of «waters of the hill» appears with the first rains after a period of long dryness. MESOHALINE WATER REGIME — Fig. 4 shows the the diagramm scheme. Salt or brackish water from 30 to 17/1.000 salinity, sometimes until 10/1.000. Turbid waters with mud in suspension, chestnut, claveyous waters; shore dirty black mud without waving bursting; the waters are warmer and shorner than those of the polihaline regime. Mangrove shore with the mangrove trees : Rhizophora mangle L., Avicennia sp., Laguncularia sp., and the »cotton tree of sea» Hibiscus sp. Fauna: the great land crab «guaimú» Cardisoma guanhumi Latr., ashore in dry firm land. There is the real land crab Ucides cordatus (L.) in wetting mud and in neigh¬ bourhood of the burrows of the fiddler-crabs of genus Uca. On stones and in the roots of the Rhizophora inhabits the brightly colored mangrove-tree-crab («aratu» Portuguese nickname) Goniopsis cruentata (Latreille) and the sparingly the big oyster Ostrea rhizophorae Guild. Lower is the region of barnacles Balanus amphitrite var. communis Darwin and var. niveus Darwin; Balanus tintinnabulum var. tintinnabulum (L.) doesn't grow in this brackish water; lower is the region of Pelecipoda with prepollency of Venus and Cytherea shell-fishes and the Panopeus mud crab; there are the sea lettuce Ulva and the Gastreropod Cerithium. The Paguridae Clibanarius which lives in the empty shells of Gasteropod molluscs, and the sessile ascidians Tethium plicatum (Lesuer) appears in some seasons. In the bottom there is a black argillous mud where the «one landed shrimps» Alpheus sp. is hidden. OLIGOHALINE WATER REGIME — The salinity is lower than 10/1.000. average 8/1.000. There are no barnacles and no sea-beetles Isopods of genus Lygia; on the hay of the shore there are several graminea. This brackish water pervades by mouthes of rivers and penetrates until about 3 kilometers river above. While there is some salt dissolved in water, there are some mud crabs of the genus Uca, Sesarma, Metasesarma and Chasmagnatus. The presence of floating green plants coming from the rivers in the waters of a region indicated the oligohaline waters, with low salt content because when the average of NaCl increases above 8/1.000 these plants die and become rusty colored.

A Leprolina "Souza-Araujo" no tratamento da lepra

The A. summarizes clinical records of four lepers treated with Leprolin “Souza-Araujo”, as follow: ist – Male, 28 years old, lepromatous case, treated during about 3 years, who received 80 injections of the antigen, being 52 by vene, 18 by muscle and 10 intradermally. Total about 100 cm³. Results: Absence of clinical signs, routine examinations negative for acidfast bacilli. Histopathology: from lepromatous became incaracteristic, with a few bacilli. Mitsuda test from negative became positive. 2nd – Male, 33 ys. old, lepromatous case. From September 1944 to February 1948 received 110 intravenous injections (57 cm³) and 10 cm³ perineurally to control neurites. His Mitsuda test was negative in 1944 and in 1945 became positive and remained so until 1948 (4 times controlled). Since Sept. 1946 became bacillus negative in his mucous, ear lobe and lymph nodes. Out of his lepromatous symptoms remained only mild atrophy of his hands. 3rd- Male, 30 ys. old, lepromatous case, treated since 1944. From 1946 to Feb. 1948 received 80 intravenous injections (high dosage: from 2 to 5 cm³), total 310 cm³ and 140 cm³ intramuscularly. His Mitsuda test was negative in 1943; became positive (from 1945 till 1948) after Leprolin treatment. Bacilloscopy became negative even in sections. Histopathology: the lesions from lepromatous changed to tuberculoid. 4th – Male, 17 years old, lepromatous case, received, from Dec. 1944 to Feb. 1948 only 88 intravenous injections of small doses of Leprolin (0,1 to 1,0 cm³). His Mitsuda remained negative from 1944 to 1946 and in 1947 became positive. Routine examinations negative for bacilli. Histopathology: the lepromataus lesions regressed to incaracteristic, without bacillus.

Dados estatísticos de viscerotomia sobre doenças e condições mórbidas do homem no Brasil: I. Schistosomose Mansônica no período de 1937-1946

Examination of 267.107 liver specimens obtained in Brazil by viscerotomy during from 1937 to 1946 inclusive revealed 5,953 Schistosoma mansoni infe¬ctions. This represents 2.23% ± 0.019 of the total number of livers studied. Data on the incidence of the disease is tabulated by states and municipios. Infected livers were found in all of the states and territories except the Territory of Amapá. Schistosomiasis is widespread in Brazil with highest incidence in the states of the Northeast. The disease is quite common in Espírito Santo and Minas Gerais as well. A study of the age distribution of cases of intestinal schistosomiasis observed among liver specimens obtained in the year 1938 showed a low inci¬dence on young children with a peak of prevalence in the 10 to 19 year age group. The purpose of this contribution is to call attention of the health autho¬rities to the extent and gravity of the problem of intestinal schistosomiasis in Brazil.

Trematódeos monogenéticos (Polistomatas) da costa brasileira I. sobre Loimos scitulus sp. n. (Loimoidae) e Tagia ecuadori (Meserve, 1938) Sproston, 1946 (Diclidophoridae)

Em continuação aos estudos dos trematódeos monogenéticos da Coleção Helmintológica do Instituto Oswaldo Cruz, descrevemos no presente trabalho uma espécie do gênero Loimos MacCallum, 1917, Loimolinae Price, 1936, loimoidae Bychowsky, 1957 que consideramos nova para a ciência, e assinalamos nova ocorrência de Tagia ecuadori (Meserve, 1938) Sproston, 1946, Tagiinae Yamaguti, 1963, Diclidophoridae Najibina & Obonikova, 1971, no Atlântico Sul. Loimos scitulus sp. n. diferencia-se das outras espécies do gênero pelos seguintes caracteres: forma e estrututra do proaptor, oótipo grande, número de testículos, posição do poro genital, filamento do ovo e forma de opistaptor. Dentre as diferenças dadas Loimos scitulus sp. n. aproxima-se de L. salpinggoides pela estrutura do proaptor, de L. secundus pela posição do poro genital; de L. winteri pelo opistaptor. Quanto aos exemplares de Tagia ecuadori por nós estudados, apesar de ter sido evidenciada uma vagina, identificamos a esta espécie, por apresentar estruturas e medidas que se enquadram nas variações dadas pelos estudiosos do grupo.

First report of Ascarophis Van Beneden, 1871: A. Brasiliensis n.sp. (Nematoda, Ascarophidinae) and Procamallanus (Spirocamallanus) Pereira/Annereaux, 1946 (Nematoda, Procamallaninae) in South America

Ascarophis brasiliensis recovered from the stomach of Trachinotus carolinus (L. 1766), is proposed as a new species and Procamallanus (Spirocamallanus) pereirai Annereaux, 1946 is redescribed from a new host: Paralonchurus brasiliensis (Steind., 1875). A. brasiliensis is more closely related to A. crassicolis Dollfus & Campana-Rouget, 1956, from which it differs mainly by the absence of cervical cuticular expansion and size of the eggs. The new species is also compared to A. cooperi johnston & Mawson, 1945 and A. girellae (Yamaguti, 1935) Campana-rouget, 1955. The validity of the proposed species is discussed.

Padrões distributivos e zoogeografia dos moluscos da plataforma continental brasileira: Parte III. Comissão Oceanográfica Espiríto Santo I

One hundred senventy-five species of marine mollusks have been identified in the Expedition Espírito Santo I. Standing out the species Margarites olivaceus (Brown, 1827); Cyclostremiscus caraboboensis Weishord, 1962; Balcis gibba Folin, 1867; Triphora compsa (Dall, 1927); Henrya af. goldmani Bartsh, 1947 and Limaea subovata Jeffreys, 1876 as they have not been previously assigned to Brazil. The analysis of the geographical distribution patterns points out the dominance of the species with thermophiles affinities. This situation evidences the importance of the Brazilian Current in the maintanance of the biogeographical structure of the studied region. However, it is the analysis of the cryophiles species that shows the Cabo Frio region as an ecological filter quite more permeable to the species with thermophile affinities than to the cryophiles ones. The existence of this barrier and the endemism rate (4.27%) characterize the region that extends from the south of Cabo Frio as a transition between the two patterns cited above. Therefore they do not corroborate in malacological parameters the proposition made by Palacio (1982) for the individualization of the Paulista Province.

Studies on Procamallanus (Spirocamallanus) pereirai Annereaux, 1946 (Nematoda: Camallanidae), with new host records and new morphological data on the larval stages

Larval stages and adults of Procamallanus (Spirocamallanus) pereirai Annereaux, 1946 are described from naturally infected Paralonchurus brasiliensis (Steindachner) (Sciaenidae) from the coast of the State of Rio de Janeiro, Brazil. The translucent first-stage larvae have a denticulate process at the anterior end, no buccal capsule or esophagus undifferentiated into anterior muscular and posterior glandular parts and an elongate tail; third-stage larvae have a tail with three terminal projections, a buccal capsule divided into an anterior portion with 12-20 ridges running to the left and a posterior smooth portion, and an esophagus with muscular and glandular regions. Fourth-stage larvae exhibit a buccal capsule lacking a distinct basal ring with ridges running to the right and a tail with two terminal processes, as in adults. New host records are reported and their role in its life-cycle are discussed.

Redescription of Tejidotaenia appendiculata (Baylis, 1947) (Cestoda: Proteocephalidea), a parasite of Tupinambis teguixin (Sauria: Teiidae) from South America

The species Tejidotaenia appendiculata (Baylis, 1947), a parasite found in teju, Tupinambis teguixin is redescribed and a new diagnosis is provided. The species is characterized by the anterior position of the ovary and the peculiar shape of suckers. It is the first record of this species in Brazil.

Variabilidade interdecadal na série secular de temperatura do ar em Santa Maria, RS

O objetivo deste trabalho foi verificar possíveis associações entre a variabilidade interdecadal das temperaturas mínima (Tmín) e máxima (Tmáx) diárias do ar e da amplitude térmica diária (ATD) em Santa Maria, RS, com a Oscilação Decadal do Pacífico (ODP). Foram usados os valores diários de Tmín e Tmáx de janeiro de 1912 a dezembro de 2009, e os valores mensais do índice da ODP do mesmo período. Há associação entre a variabilidade interdecadal da Tmín e Tmáx e da ATD com a ODP nesse local. Na fase fria da ODP, de 1947-1976, houve decréscimo nas Tmín e Tmáx. Nas duas fases quentes da ODP, 1925-1946 e de 1977-1998, houve aumento na Tmín no primeiro período e na Tmáx no segundo período. Durante a fase fria da ODP, de 1947-1976, houve redução da ATD, pela diminuição da Tmáx média e máxima. Houve aumento na ATD, no primeiro semestre na fase fria atual (1999-2009), em razão da diminuição na média da Tmín. Esses ciclos de aquecimento e resfriamento, na escala decadal, podem nortear estratégias de adaptação e mitigação na agricultura, por meio do melhoramento genético e desenvolvimento de cultivares tolerantes a tais oscilações de temperatura.

The Brazilian and patagonian fishes of the wilkes expedition: 1838-1842

Na viagem efetuada à volta do mundo pela U. S. Exploring Expedition mais conhecida pelo nome de Expedição Wilkes e durante o período em que a mesma operava no Atlântico Ocidental, foram visitadas as regiões do Rio de Janeiro e da Patagônia. Por ocasião da festa comemorativa do centenário da The American Philosophical Society, de Filadélfia, ocorrida a 23 de Fevereiro de 1930, o autor teve a oportunidade de apresentar uma nota prévia da qual constava uma lista de peixes capturados durante o cruzeiro da Expedição. Teve, então, o ensejo de examinar o diário redigido pelo Dr. Charles Pickering, botânico da Expedição, nele encontrando anotações valiosas para a História Natural, considerada em seu sentido amplo, detalhes a respeito das localidades percorridas e relações extensas de animais e plantas, além de diversos representantes pertencentes a outros grupos. Sob o ponto de vista histórico, os comentários aí constantes são de importância significativa. Em muitos casos, essas apreciações fornecem base sólida para a efetivação de estudos faunísticos, de caráter comparativo, muito instrutivos e úteis. O autor examinou a coleção de peixes da Expedição Wilkes que se encontra no Museu Nacional dos Estados Unidos, em Washington, acervo esse gentilmente posto à sua disposição para estudo. Dessa maneira, no presente trabalho, fornece matéria de amplo interesse histórico, visando com isso lançar alguma luz sobre a imensa fauna do Brasil e da Argentina. Baseando-se nos dados fornecidos por Pickering, o autor divulga dados curiosos a respeito da baía do Rio de Janeiro e adjacências, no ano de 1838. Segue-se uma lista contendo a diagnose de 82 espécimes de água doce, salobra e salgada, estudados e comparados com outros de várias procedências. Referindo-se ao Rio Negro, descreve o autor o aspeto da região patagônica, durante certo período de 1839, fazendo comentários a respeito de 7 espécies de peixes nela, encontradas.
