Abstract: En | Text: En | PDF: En

Abstract Biological scientific collections provide a robust framework for studying past and present biodiversity through different perspectives. Mapping and sharing their information content may aid to reduce biodiversity shortfalls, such as those observed in annelid polychaetes. These are among the most important groups of marine invertebrates, playing pivotal ecological roles in benthic habitats, and being important bioindicators. The main scientific polychaete collections in Brazil are concentrated in four institutions: Museum of Zoology and Oceanographic Institute of University of São Paulo, Museum of Biological Diversity of State University of Campinas, and National Museum of Federal University of Rio de Janeiro. This paper explores the history and taxonomic knowledge of these collections, offering a comprehensive overview of their current statuses and highlighting challenges for the future. Together, these four collections safeguard over 300,000 samples from 68 polychaete families and 1,267 species representing 89% of the families and 94% of the species reported for the Brazilian coast. Among these samples, 252 are holotypes, which have rapidly increased in numbers in the past couple of decades due to the rise of species originally described from Brazil. Despite the long-standing presence of some of these institutions, the organization of their polychaete collections only began in the late 1990s and early 2000s. The organization of these official collections allowed the rescue of samples scattered around the institutions and made them available for further studies. All the Brazilian coastline is represented in these collections, but São Paulo and Rio de Janeiro are overrepresented. Historical factors, such as collection mergers, expeditions, and targeted projects, also influenced the geographic distribution of samples. Brazilian scientific polychaete collections have significantly advanced in the last 15 years. However, the associated data still needs better structuring and accessibility to the scientific community via open-access online platforms allowing further investigation on Brazilian polychaete biodiversity. perspectives shortfalls polychaetes invertebrates habitats bioindicators Campinas future Together 300000 300 000 300,00 6 1267 1 267 1,26 89 94 coast 25 holotypes longstanding long standing s 2000s studies overrepresented factors mergers expeditions projects years However openaccess open access 30000 30 00 300,0 126 26 1,2 8 9 2 3000 3 0 300, 12 1,

Abstract Increasing habitat modification and species loss demand consistent efforts to describe and understand biodiversity patterns. The BIOTA/FAPESP Program was created in this context and it has been a successful initiative to promote studies on biodiversity and conservation in Brazil. The BIOTA/Araçá is an interdisciplinary project that provided a detailed evaluation of the biodiversity of Araçá Bay, a coastal seascape located on the North coast of the state of São Paulo, Southeast Brazil. The bay encompasses multiple habitats, such as beaches, mangroves, rocky shores, and a tidal flat, and provides important ecosystem services. Unfortunately, the bay is the subject of complex social-environmental conflicts that oppose economic, social, and environmental demands (i.e., the expansion of neighboring harbor activities vs. small-scale artisanal fisheries and protection of biodiversity). The present study presents a survey of the benthic species occurring in the different habitats of Araçá Bay, including data obtained during the BIOTA/Araçá project and previous assessments of the area. The benthic species play an important role in marine environments and studying the diversity of these organisms that live associated with the bottom is indispensable for comprehending the environment’s functioning. The macrofauna, meiofauna, and microorganisms associated with soft and hard bottom were listed, and additional information, such as the habitat and geographical distribution, were provided for each species. The checklist includes 826 species, almost 70% recorded during the BIOTA/Araçá project. The most speciose taxa were the annelids (225 spp.), mollusks (194 spp.), and crustaceans (177 spp.). Seven benthic species are endemic to Araçá Bay, 14 are considered threatened, and seven are economically exploited. Furthermore, the bay is the type locality of many taxa, and 11 new benthic species were described based on specimens sampled during the project. This project shows the importance of Araçá Bay as a unique biologically rich environment and highlights the need for conservation efforts in light of the current threats. patterns BIOTAFAPESP BIOTA FAPESP Brazil BIOTAAraçá Paulo beaches mangroves shores flat services Unfortunately socialenvironmental social economic i.e., ie i e (i.e. vs smallscale small scale biodiversity. . biodiversity) area s functioning macrofauna meiofauna listed information distribution 82 70 225 (22 spp., spp spp. , spp.) 194 (19 177 (17 spp.. 1 threatened exploited Furthermore threats i.e. (i.e 8 7 22 (2 19 (1 17 i.e 2 (

Resumo O aumento da modificação dos habitats e da perda de espécies demanda esforços consistentes para descrever e compreender os padrões de biodiversidade. O programa BIOTA/FAPESP foi criado nesse contexto e é uma iniciativa de sucesso para promover estudos em biodiversidade e conservação no Brasil. O BIOTA/Araçá é um projeto interdisciplinar que promoveu uma avaliação detalhada da biodiversidade da Baía do Araçá, um ecossistema costeiro localizado ao Norte do estado de São Paulo, Sudeste do Brasil. A baía engloba múltiplos habitats, tais como praias, manguezais, costões rochosos, e uma planície de maré, e também fornece importantes serviços ecossistêmicos. Infelizmente, a baía está sujeita à conflitos sócio-ambientais complexos que contrastam demandas econômicas, sociais e ambientais (i.e. a expansão das atividades do porto vizinho vs. a pesca artesanal de pequena escala e a proteção da biodiversidade). O presente estudo apresenta um levantamento das espécies bentônicas que ocorrem nos diferentes habitats da Baía do Araçá, incluindo dados obtidos durante o projeto BIOTA/Araçá e de investigações realizadas anteriormente na área. As espécies bentônicas desempenham um papel importante no ambiente marinho, e estudar a diversidade desses organismos que vivem associados ao fundo é indispensável para compreender o funcionamento do meio ambiente. A macrofauna, meiofauna, e microorganismos associados aos fundos consolidado e inconsolidado foram listados, e informações adicionais foram fornecidas para cada espécie, tais como a distribuição geográfica e nos habitats. O checklist inclui 826 espécies, quase 70% registradas durante o projeto BIOTA/Araçá. Os taxa mais especiosos foram os anelídeos (225 spp.), moluscos (194 spp.), e crustáceos (177 spp.). Entre as espécies bentônicas listadas, sete são endêmicas da Baía do Araçá, 14 são consideradas ameaçadas de extinção, e sete são exploradas economicamente. A baía é a localidade tipo de vários taxa, e 11 novas espécies bentônicas foram descritas com base em espécimes amostrados durante o projeto. Este projeto mostra a importância da Baía do Araçá como um ambiente de riqueza biológica única e demonstra a necessidade de esforços para a sua conservação considerando as atuais ameaças.

Resumo O Brasil é caracterizado como um país megadiverso e uma das prioridades no conhecimento e conservação dessa biodiversidade é seguramente a melhoria das coleções biológicas. Estas representam patrimônio biológico, científico, cultural e genético de um país, e sua preservação depende de um esforço coletivo de pesquisadores, instituições e do poder público. Com relação às coleções biológicas marinhas de invertebrados e algas, o estado de São Paulo representa uma alta porcentagem do acervo nacional, com cinco principais coleções depositadas em instituições estaduais. Atualmente estas coleções salvaguardam a grande maioria do acervo marinho estadual e compõem um dos maiores do país. Assim sendo, o objetivo desta pesquisa é o de apresentar informações sobre as coleções biológicas marinhas do estado de São Paulo, estado atual, financiamentos e perspectivas futuras, criando oportunidades de comunicação e considerando os fatores que impactam o desenvolvimento das mesmas. O apoio financeiro da Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) às instituições paulistas extravasa os limites do estado, visto que muitas pesquisas abordam áreas mais abrangentes e/ou estabelecem parcerias diversas com outras instituições não paulistas. Isso se reflete inclusive na abrangência taxonômica e geográfica das coleções biológicas do Estado, uma vez que estas mantêm espécimes/espécies de diferentes regiões do país, ou mesmo de outros países. No entanto, vale ressaltar que não basta investir em expedições de coleta para enriquecimento das coleções sem valorizar a formação de pessoal qualificado, tanto para a curadoria dos acervos quanto para o refinamento taxonômico.

Abstract Brazil is characterized as a megadiverse country, and one of the factors that guarantees the knowledge and preservation of this biodiversity is an improvement in the biological collections. They represent a country's biological, scientific, cultural, and genetic heritage and their preservation depends on a joint effort of researchers, institutions, and public authorities. Marine biological collections of invertebrates and algae of the state of São Paulo represent a high percentage of the national collections, with five biological collections deposited in state institutions. Currently, these collections safeguard the vast majority of the state's marine collection and make up one of the largest in the country. Therefore, the objective of this research is to present information on marine biological collections in the state of São Paulo, their current status, funding, and future perspectives, creating communication opportunities and considering the factors that impact their development. Support from the São Paulo Research Foundation (FAPESP) surpasses state limits, since many studies address broader areas and/or establish diverse partnerships with other institutions from outside São Paulo. This is reflected in the taxonomic and geographic scope of the biological collections in the state, since these host specimens/species from different regions of the country, or even from other countries. However, it is worth mentioning that it is not enough to invest in expeditions to enrich the collections without valuing the training of qualified personnel, both for the collections maintenance and for their taxonomic refinement.

Abstract: En | Text: En | PDF: En

The postlarval development of Nicolea uspiana (Nogueira, 2003), a small intertidal terebellid polychaete from rocky habitats on the southeastern and southern Brazilian coast, was studied based on postlarval, juvenile and adult specimens. The specimens, ranging from 8 to 43 segments, were collected between May 2006 and May 2007. The youngest postlarval specimen was found crawling outside of the tube. In specimens at different stages of growth, the number of ocelli and tentacles increased; the first pair of nephridial papillae appeared early (before 8-segmented specimen), and the second and third pairs appeared later (31-segmented specimen); the circulatory system only developed when the first pair of branchial bulbs arose (32-segmented specimen), and the second branchial pair appeared later (40-segmented specimen); and the inversion of the uncini positions in some rows occurred in the transition from larva to juvenile (17-segmented specimen). In the course of development, segments 2-3 lost the notochaetae, and segments 3-4 lost the neurochaetae. The changes involved in the development from postlarval to adult animals are illustrated by SEM micrographs and photographs.

Este trabalho foi realizado na região entremarés das praias Barra Velha, Perequê e Engenho d'Água, situadas na Ilha de São Sebastião (Estado de São Paulo, Brasil), com o objetivo de estudar a composição, abundância e zonação da taxocenose dos poliquetas. Quatro setores estruturalmente diferentes foram delimitados, sendo dois na Barra Velha (I e II), um no Perequê e um no Engenho d'Água. Cada setor foi dividido em 3 níveis entremarés (inferior, intermediário e superior), nos quais 5-6 amostras aleatórias foram tomadas sazonalmente utilizando um delimitador com 0,01 m2 de área. Laeonereis acuta, Capitella capitata e Heteromastus filiformis ocorreram predominantemente nos níveis superiores e Scoloplos (Leodamas) sp. e Cirriformia tentaculata nos inferiores. A complexidade estrutural do Engenho d' Água, caracterizado por fragmentos rochosos misturados ao sedimento, sustentou a fauna de poliquetas mais rica e diversificada dentre os setores. A salinidade da água intersticial e o teor de matéria orgânica foram os principais parâmetros determinantes da zonação nestes locais.

This study was performed in the intertidal zone of Barra Velha, Perequê, and Engenho d'Água beaches, located on São Sebastião Island (São Paulo State, Brazil), to assess the composition, abundance, and zonation of the polychaete community in the intertidal zone. Four structurally different sectors were established, two on Barra Velha (I and lI), one on Perequê, and one on Engenho d'Água. Each sector was divided into 3 tidal levels (lower, middle, and upper), in which 5 or 6 random samples were taken seasonally using a corer of 0.01 m2 in area. Laeonereis acuta, Capitella capitata, and Heteromastus filiformis dominated in the upper tidal levels, and Scoloplos (Leodamas) sp. and Cirriformia tentaculata in the lower levels. The structural complexity of Engenho d'Água, caused by rocky fTagments mixed with sand, supported the richest and most diverse polychaete fauna of ali the sectors. The salinity of the interstitial water and the organic matter content were the principal factors related to the zonation patterns at these sites.

Estudou-se a variação anual da comunidade de moluscos em dois ambientes entremarés constituídos por areia e fragmentos rochosos <300 mm) no Canal de São Sebastião, Brasil. As amostras foram obtidas mensalmente entre agosto de 1995 e julho de 1996 nas praias São Francisco (continente) e Engenho d'Água (Ilha de São Sebastião). Uma marcante redução na abundância e diversidade foi associada às mudanças estruturais do ambiente, causada por ressacas do mar no início do verão (dezembro), e ao aumento no fluxo de esgotos domésticos neste período. Em áreas onde estes eventos não foram evidentes, não houve grande alteração na composição faunística, e as pequenas oscilações foram atribuídas ao recrutamento de populações numericamente importantes. Ambos os fatores naturais e antrópicos podem estar atuando em conjunto para determinar a organização da comunidade nestes ambientes, tal como ocorre em praias arenosas típicas.

The temporal variation in molluscan communities was studied in two intertidal substrates composed of sand and rock fragments <300 mm) in São Sebastião Channel, Brazil. Samples were taken between August 1995 and July 1996 in São Francisco (mainland) and Engenho d'Água (São Sebastião Island) beaches. A pronounced decrease in abundance and diversity of molluscs was associated with changes in the structure of the environment, caused by sea storms in the beginning of the summer (December), and by the increase of waste water discharge in this same period. Areas not subjected to such events showed no evident modifications in mollusc fauna structure during the sampling period, and the small oscillations observed were attributed to population recruitment. Both natural and human factors may be acting together in determining the community organization in these environments, as is also in typical sandy beaches.

Three species of the family Phyllodocidae and two of Hesionidae were found in colonies of the bryozoan Schizoporella unicornis (Johnston) on the beaches of Ubatuba and São Sebastião, São Paulo State, Brazil. Among these, Eumida sanguinea (Phyllodocidae) is registered for the first time on the Brazilian coast. Among the other species Ophiodromus pugettensis (Hesionidae) was one of the most abundant polychaetous annelids of the bryzoan fauna.

Na execução de um programa de levantamento das faunas demersal e epibentônica da plataforma do litoral norte do Estado de São Paulo, foram tomadas, em um período de dois anos, 28 amostras da fauna de fundo, utilizando-se redes tipo ottertrawl abrangendo a área compreendida entre as ilhas Anchieta, Vitória e das Couves. A despeito do pequeno tamanho das redes - 30 pés na tralha de bóia -, os resultados, quanto a número e diversidade dos peixes encontrados na área, pareceram ser muito significativos e justificar a comunicação atual. Um total de 97 espécies de peixes, tanto ósseos quanto cartilaginosos, foi obtido em 28 capturas controladas, durante os anos de 1978 e 1979, A família melhor representada foi, como previsto, a dos Sciaenidae; porém, representantes de Rajidae, Bothidae e Cynoglossidae foram também abundantes. Lophius gastrophysus e Merluccius hubbsii, ocorreram apenas em profundidades acima de 30 m, o que concorda com sua distribuição conhecida na costa do extremo sul do país, Uma lista sistemática das espécies e seus nomes populares, quando disponíveis, é dada.

A two-year program of biological sampling was carried out on the area comprised by the islands of Anchieta, Vitória and Couves on the northern coast of São Paulo State, Brazil. Most of the samples were collected by otter-trawl since the demersal fish were the main interest of the study. In spite of the small size of the nets used - only 30 feet on the mouth - the results obtained as to the number and diversity of the fish found in the area seemed to be significant enough to justify the present communication. As many as 97 species of bony and cartilaginous fish were obtained from 28 controlled catches, along the years 1978-1979. The best represented family, as could be expeoted were the Sciaenidae but Rajidae, Bothidae and Cynoglossidae were also abundant. Lophius gastrophysus and Merluccius hubbsii. occurred only in depths above 30 m, in agreement with their known distribution in the far southern coast of Brazil. A systematic list of the species and their common names, when available, is given.

Four species of Polynoidae, found in colonies of the bryozoan Schizoporella unicorns (Johnston), are here described. Among these Scalisetosus gracilis is a new species for science, and Halosdna glabra Hartman and Harmathöe macginitiei Pettibone, cited by the first time for Brazilian coast. Lepisdonotus caeruleus was the most abundant species of the family. Scalisetosus gracilis sp. nov. is characterized by the elytra with long and bifid papillae scattered on the surface as well as on external borders and distinct notosetae and neurosetae.
