Item Pycnogonida associado à macroalgas nos recifes areníticos nas praias da Pina e Boa Viagem, Pernambuco - Brasil(2020-01-29) Nascimento, Lorena Nunes; Pinto, Stefane de Lyra; http://lattes.cnpq.br/2971017849516459; http://lattes.cnpq.br/3510393256209062Picnogonids are benthic or pelagic marine arthropods, with approximately 1340 recent species considered valid, which are distributed globally from tropical to polar seas. They are generally called "sea spiders" because of their superficial resemblance to real terrestrial spiders. Little information is found on the fauna of pycnogonids off the coast of Brazil, where the group has been little and sporadically addressed in the literature. In this sense, the objective of this work was to carry out the identification of specimens associated with macroalgae collected on the beaches of Pina and Boa Viagem, south coast of the state of Pernambuco. At Pina beach the collection was carried out from May to July / 2018 (rainy season) and September to November / 2018 (dry season) and in Boa Viagem from January to March / 2019 (dry season) and May to July / 2019 (rainy season). In both beaches, collections were carried out manually in the mesolitoral region during low tide. For taxonomic identification of pycnogonids, this was carried out down to the species level, with the aid of a stereomicroscope, using specialized bibliography. A total of 258 specimens were counted, distributed in 03 families, 03 genera and 08 species. The species Anoplodactylus ganchiformis Lucena and Christoffersen, 2018 was considered very frequent (100%), standing out in the rainy season in both investigated beaches. At Pina beach, the species that contributed most in terms of relative abundance were: Anoplodactylus stictus Marcus, 1940 (57.1%) in the dry season and A. ganchiformis (47.4%) in the rainy season. The species A. stictus also showed a high contribution in terms of relative abundance on the Boa Viagem beach, in the dry (42.4%) and rainy (57.8%) periods. The diversity indexes were also checked and it was noted that the month of November was the only one that assumed a zero index. The species Anoplodactylus batangensis (Helfer, 1938) and Anoplodactylus evelinae Marcus, 1940 had their records expanded for the beaches in question. The species A. stictus had its record expanded to the state of Pernambuco and the species Anoplodactylus ricardoi Lucena and Christoffersen, 2018 and A. ganchiformis had their first records for Pernambuco and the second for the Northeast. It is hoped that these records can contribute and encourage the search for more work, in order to obtain a better understanding of the systematics and distribution of Pycnogonida, since little information is found about this fauna.Item Macrofauna em ambientes recifais de praias urbanas do Recife - PE, Brasil(2020-10-27) Santos, Karollayne Danielly da Silva; Alves, Marcos Souto; http://lattes.cnpq.br/7568351870637048; http://lattes.cnpq.br/4176625803318031The beaches of Pina and Boa Viagem, Recife-PE, are urban beaches and present in addition to ecological importance, socioeconomic importance. In order to characterize the macrofauna of the aforementioned beaches, aiming to provide recent data on the quali-quantitative composition of the same, monthly collections were carried out, always at low tides daytime syzygy, from May to July (rainy season), and September to November (dry season) 2018 at Pina beach, and from January to March (dry season), and May to July (rainy season) 2019 at Boa Viagem beach. The macroalgae were collected with the aid of plastic bags and deposited in plastic containers containing water from the site, with three samples of macroalgae per month. Regarding the reef macrofauna, specimens were collected manually, with the aid of tweezers and deposited in plastic containers. In the laboratory, the macrofauna associated with macroalgae was identified at the level of large groups and accounted for. Mollusks obtained from macroalgae, as well as decapod crustaceans and molluscs collected on reefs, were identified at the species level with the help of specialized literature. Associated with macroalgae, 11 and 13 zoological taxa were removed for the beaches of Pina and Boa Viagem, respectively, with Copepoda being the dominant one on Pina beach, and Isopoda and Amphipoda Gammaroidea in the dry and rainy periods, respectively, on Boa Viagem beach. As for gastropods associated with macroalgae, 18 species were obtained at Praia do Pina, and 22 at Boa Viagem beach. Comparing the seasonal periods, on both beaches the dry period presented greater wealth than the rainy one. Eulithidium affine stood out for being the dominant species on Pina beach, as well as on Boa Viagem beach in the rainy season, with Mitrella ocellata being the dominant one in the dry season. Regarding the reef macrofauna, 10 species were obtained at Pina beach and 12 at Boa Viagem beach. Comparing the two seasonal periods, the rainy season was the one that showed the greatest wealth and abundance at Pina beach, while at Boa Viagem beach it was the dry period. In both beaches studied, Stramonita haemastoma and Pachygrapsus tranversus, were the species of mollusk and decapod crustacean respectively, which presented greater abundance. Regarding the frequency of occurrence, on the beach of Pina Stramonita haemastoma was the most frequent mollusk, while on the beach of Boa Viagem the species Brachidontes exustus, Fissurella clenchi and Stramonita haemastoma were the most frequent occurrence. Among decapod crustaceans, Pachygrapsus tranversus was the one with the highest frequency on the two beaches studied. Callinectes exasperatus and Callinectes ornatus would be a new occurrence record for Boa Viagem beach. The macrofauna obtained in the present study, showed less abundance of individuals and less value of wealth, when compared to previous works, which may be related to anthropic actions, such as increased trampling. Despite this, it is considered that the two beaches studied showed good biological diversity, since they are strongly impacted.Item Diversidade da comunidade associada à Carijoa riisei em naufrágios de diferentes profundidades em Pernambuco(2019-12-10) Oliveira, Camilla Silva de; Gomes, Paula Braga; http://lattes.cnpq.br/3289333472399959; http://lattes.cnpq.br/7484128728382844The octocoral Carijoa riisei is distributed in the Western Atlantic Ocean, Pacific, Caribbean and most recently in Mexico, it can be found at depths of more than 30 meters, including in Pernambuco shipwrecks. This species has an arborescent estolonial structure that provides a favorable environment for the development of various organisms, among which are macroinvertebrates, organisms of utmost importance for ecosystem processes. This work aims to investigate if the difference in depth between Pernambuco shipwrecks influences the fauna composition associated with C. riisei. The octocoral samples were collected in four Pernambuco shipwrecks located in the Pernambuco Artificial Shipwreck Park, in Recife, with different depths (between 20 and 30 meters), during the dry (December) and rainy (July) seasons of 2018, using SCUBA equipment. Later, in the laboratory, the colonies passed by washing processes and the macrofauna was retained in a 250 μm sieve, sorted, counted and identified to the smallest possible taxonomic group. In total, 3143 individuals associated with C. riisei were collected, distributed in 52 taxa. The Amphipoda and Polychaeta groups were the most representative in all shipwrecks, with a relative abundance of 66% (dominant taxon) and 22% (slightly rare taxon), respectively. The Taurus shipwreck had a higher species richness associated with the octocoral colonies than the other shipwrecks, especially during the rainy season. The composition of the associated fauna was different among the shipwrecks, but the difference in depth between the shipwrecks was not relevant for this differentiation. Therefore, other abiotic factors may have been responsible for this difference in species richness and composition among shipwrecks.Item Relatório de Estágio Supervisionado Obrigatório (ESO), realizado na Associação R3 Animal (Florianópolis - SC, Brasil): ocorrência de Plasmodium sp. em pinguim-de-magalhães (Spheniscus magellanicus) - Relato de caso(2020-10-30) Bezerra, Taciana Cássia Santos; Silva, Jean Carlos Ramos da; http://lattes.cnpq.br/8705354960174177; http://lattes.cnpq.br/3391064014990146This work aims to report the activities made by the student Taciana Cássia Santos Bezerra during her mandatory supervised internship (ESO) at Centro de Pesquisa, Reabilitação e Despetrolização de Animais Marinhos (CePRAM) through Projeto de Monitoramento de Praias na Bacia de Santos (PMP-BS) in Florianópolis, at the Associação R3 Animal, on sea animals rehabilitation from March 2nd to March 30th, 2020, with a 436-hour workload, under the guidance of Prof. Jean Carlos Ramos da Silva and supervision by the veterinarian Dr. Cristiane Kiyomi Miyaji Kolesnikovas.
