Primer Inventario De Vertebrados De La Reserva Natural Privada El Morejón, Campana, Provincia De Buenos Aires
Rev. Mus. Argentino Cienc. Nat., n.s. 21(2): 195-215, 2019 ISSN 1514-5158 (impresa) ISSN 1853-0400 (en línea) Primer inventario de vertebrados de la reserva natural privada El Morejón, Campana, provincia de Buenos Aires Valeria BAUNI1*; Sergio BOGAN1, Juan Manuel MELUSO1, Marina HOMBERG1 & Adrián GIACCHINO1 1Fundación de Historia Natural Félix de Azara - Departamento de Ciencias Naturales y Antropológicas, Universidad Maimónides, Hidalgo 775 piso 7, C1405BCK, Ciudad Autónoma de Buenos Aires, Argentina. E-mail: *[email protected] Abstract: First inventory of vertebrates in the private natural reserve El Morejon, Campana, Buenos Aires province. The knowledge of the species present in a natural protected area provides indispensable infor- mation to valorate it correctly and to plan its management. The private natural reserve El Morejón is located in Campana Department, Buenos Aires province, and 340 ha are protected, with natural and semi-natural en- vironments in Pampas ecoregion. The reserve has several artificial lagoons, two water courses that go across it, grasslands, flood plains, sedges and forest relicts. The objective of this work was to compile an inventory of the biodiversity of vertebrates registered in the reserve over eight years of periodic surveys. A total of 243 vertebrate species were recorded: 61 fishes, 150 birds, 11 mammals, 10 reptiles and 11 amphibians. Representative species of the environments protected in the reserve were recorded, as well as threatened species such as the Long-winged Harrier (Circus buffoni), the capybara (Hydrochoerus hydrochaeris) and the D’Orbigny’s turtle (Trachemys dor- bigni). The recorded biodiversity over the years turned out to be much higher than expected and these surveys allowed us to conclude that this anthropic wetlands can host numerous communities, being areas of breeding, refuge and migratory scale of fauna. -
From Lake Guaíba: Analysis of the Parasite Community
Parasitology Research https://doi.org/10.1007/s00436-018-5933-4 ORIGINAL PAPER Helminth fauna of Megaleporinus obtusidens (Characiformes: Anostomidae) from Lake Guaíba: analysis of the parasite community E. W. Wendt1 & C. M. Monteiro2 & S. B. Amato3 Received: 7 September 2017 /Accepted: 15 May 2018 # Springer-Verlag GmbH Germany, part of Springer Nature 2018 Abtract Structure of the helminth community of Megaleporinus obtusidens collected in Lake Guaíba was evaluated, and the results indicated that the diversity of helminth species was probably determined by fish behavior and eating habits. The influence of sex, weight, and standard length of hosts for parasitic indices was also analyzed. Sixteen helminth species were found parasitizing M. obtusidens, including the following: platyhelminths, with the highest richness, represented by one species of Aspidobothrea; four species of Digenea; and eight species of Monogenea; the latter, presented the highest prevalence. Rhinoxenus arietinus,foundin nasal cavities, had the greater abundance, and was the only species classified as core. The prevalence of Urocleidoides paradoxus was significantly influenced by the sex of the host; females had the highest values. Abundance was weakly influenced by fish weight and the body length of the hosts. Urocleidoides sp. had its abundance weakly influenced by the host weight. The other helminths were not influenced by biometric characteristics of the hosts. The total species richness was similar between male and female fish, and both had 14 helminth species of parasites. Keywords Host–parasite relationship . Fish biology . Lake environment . Southern Brazil Introduction It is found from north to south in Brazil, as well as in Argentina, Uruguay, and Paraguay (Britski et al. -

A. minuta does not feed while brood- ing. It consumes a wide range of prey, including molluscs and crustaceans, and can be regarded as a generalist or opportunistic predator. The purple mussel Perumytilus purpuratus was the most abundant prey item (57.6%). -

ZooKeys 963: 1–36. https://doi.org/10.3897/zookeys.963.52234 Abstract An increase in richness of benthic marine mollusks towards high latitudes has been described on the Pacific coast of Chile in recent decades. This considerable increase in diversity occurs specifically at the beginning of the Magellanic Biogeographic Province. Within this province lies the Strait of Magellan, considered the most important channel because it connects the South Pacific and Atlantic Oceans. These characteristics make it an interesting area for marine research; thus, the Strait of Magellan has histori- cally been the area with the greatest research effort within the province. -

Fish larvae, 350 of each species, were stocked separately in 16 fiber-cement tanks (500 L), from which, three larvae of each species were collected every three days, for 36 days. -
Relatório Da Iii Expedição Científica Do Baixo São Francisco
RELATÓRIO DA III EXPEDIÇÃO CIENTÍFICA DO BAIXO SÃO FRANCISCO ORGANIZAÇÃO: Prof. Dr. Emerson Soares - UFAL Prof. Dr. José Vieira Silva – UFAL Financiadores e patrocinadores: Maceió - AL Julho de 2021 O PROGRAMA DAS EXPEDIÇÕES CIENTÍFICAS DO SÃO FRANCISCO O programa surgiu com o pretexto de bioprospectar, conhecer e divulgar a situação do Baixo Rio São Francisco, quanto aos aspectos sociais das comunidades ribeirinhas, comunidade de pescadores, situação da pesca, identificar os impactos e a qualidade da água do rio, a ictiofauna, problemas ocasionados pelo represamento, assoreamento, desmatamento, avaliar os poluentes presentes no ambiente aquático e uso de agrotóxicos, e os efeitos da cunha salina sobre as comunidades ribeirinhas e o ambiente e propor ações mitigadoras através de programas de educação ambiental. O intuito do projeto é alavancar na região, uma nova atividade participativa por intermédio do conhecimento através do monitoramento dos principais indicadores sociais, econômicos e dos impactos ambientais, assegurando a qualidade e segurança alimentar. Tem o enfoque de chamar a atenção para a situação do rio, seus problemas e divulgar para os principais órgãos de fomento e governantes, propondo ações para mitigar os impactos e degradação da qualidade ambiental. Avaliando a necessidade de gerar políticas públicas embasadas em dados científicos, as expedições científicas propõem a elaboração de grande diagnóstico participativo e multidisciplinar sobre a situação econômica, social e ambiental da região do Baixo São Francisco, avaliando
