Two new species of Paraopisthosyllis are described herein, P. correiae sp. nov. (State Pernambuco, NE Brazil) and kuluguhin (Philippines). represents the first record for genus in Brazilian waters it is also second known to occur outside Pacific Ocean. This characterized by having a marked color pattern, with transverse red stripe between dorsal cirri on each segment an inverted V anteriorly posteriorly some segments, small papillae body, large, distinct cirri, compound chaetae elongated,...
The genus Exogonoides Day, 1963, was described probably based on a single specimen, broken into two pieces (Aguado & San Martín 2008) and no other specimens of the type species, E. antennata were ever found, which characterizes this species and, until now, very Exogonoides, as 'singletons' (Lim et al. 2012). Although member Syllidae Grube, 1850, positioning in family recently questioned 2008), since pharynx holotype dissected for original description not preserved with resulting that...
Perna perna mussel spat were suspended from ropes on a long-line cultivation, at Coqueiro´s Beach, Anchieta, South-eastern Brazil, in order to quantify the fouling community structure and its effects growth biomass of mussels. Half had removed monthly, half foulingleft until end experiment. Monthly samples thirty mussels each group measured their determined. The organisms identified, quantified evaluated monthly basis. After ten months, cleaned treatment significantly larger heavier (ANOVA;...
Abstract Aim Knowledge gaps and sampling bias can lead to underestimations of species richness distortions in the known distribution species. The goal this study is identify potential biases marine organisms at Western Atlantic Ocean, determine their causes assess its effect on biodiversity metrics. We tested interference with representation environmental conditions, potentially affecting model predictions. Location Ocean. Methods This compiled data online institutional databases. analysis...
This study reviews the data published on ecology of polychaete annelids family Syllidae associated with sponges (Porifera) and provides additional empirical from samples collected at Paiva Beach (northeastern Brazil). literature review Web Science Scopus databases, together sources information, to provide best possible overview available ecological relationships between these organisms. identified a total 76 papers reporting 68 associations syllids sponges, which involved 61 syllid species...
A new species of Exogone, E. gigas sp. n., is described herein, together with africana, arenosa, dispar, naidinoides, rolani, and simplex, collected along the Brazilian coast, including morphological details. The distribution breviantennata expanded to include states Espírito Santo, Paraíba Pernambuco. Exogone n. characterized by having a large median antenna, absence dorsal cirri on chaetiger 2, triangular process minute spines shaft spiniger-like chaetae 2. specimens are compared...
Abstract Aim Understanding the factors determining marine community variations is important for biogeography and conservation. Beta diversity a metric mapping species composition between communities regionalizing biota. Ecoregions are commonly used regionalization, but their empirical testing has been limited. Our aim to map in Western Atlantic, identify variables related these variations, regionalize areas based on distribution. Additionally, we test whether currently proposed ecoregions...
This paper evaluated the effectiveness of four types oyster spat collectors, made with recycled materials, in recruitment mangrove Crassostrea spp. at five sites Benevente river estuary, Anchieta District and on two islands Piúma District, both Espírito Santo State. The collectors were of: 1- shells, 2- PET bottles, 3- car tires 4- tiles, all them suspended by ropes tied to roots Rhizophora mangle or mussel long-lines. number recruited each collector their shell lengths registered bimonthly,...
Two new species of Odontosyllis were found in samples collected mainly on rocky shores off the states São Paulo (SE Brazil) and Paraíba (NE Brazil). aracaensis sp. nov., O. guarauensis are herein described compared to their most similar congeners. A key for Brazil is provided, relevant morphological characters genus, based falcigers morphology, summarized with those newly species. The current state knowledge genus briefly discussed.
The demand for alternative food sources is currently in evidence the world and, therefore, culture of animal species considered not conventional makes this theme relevant and appropriate. In present study, Pomacea lineata bridgesii, each with three stowage densities (0.5 [T1], 1 [T2], 1.5 [T3] animal/L), were tested. They analyzed regarding growth rate, weight gain, final biomass, feed conversion percentage survival. There was any statistically significant difference between different both...
AbstractTwo new species of Haplosyllis collected along the coast off northeastern Brazil are described. amphimedonicola sp. nov. lives in close association with sponge Amphimedon viridis and is characterized by having midbody dorsal cirri alternating long (with 3–7 articles) short 1–3 articles), not reaching half body width. Ciliated anus dorsally pair smooth to irregularly articulated anal cirri; chaetae bidentate, often eroded tips, main fang about same length or shorter than shaft width,...
Brazilian specimens of Branchiosyllis cf. exilis, B. tamandarensis sp. n., Haplosyllis lattigae H. loboi, Opisthosyllis brunnea and O. viridis are described illustrated herein, from recently collected material; also, the distributions amphimedonicola rosenalessoae expanded to other localities in states Paraíba Pernambuco. n. was found associated with sponges is characterized by having a flattened, ribbon-like body, longitudinal line mid-dorsal papillae, peristomium dorsally inconspicuous,...
We present herein the first records for Amblyosyllis, Eusyllis and Perkinsyllis from northeastern Brazil, describing illustrating Amblyosyllis sp., kupfferi E. lamelligera, which are compared to morphologically most similar congeners; a brief diagnosis is provided nonatoi, Odontosyllis aracaensis, O. guarauensis, guillermoi biota, described southeastern Brazil. In addition, new species of described, brevichaetosa sp. n., characterized by having short, bidentate falciger blades with inverted...
We compiled the records for genus Salvatoria from Brazilian coastal and oceanic habitats, collected by several projects along years. Here we present 12 species, eight of which already reported– S . breviarticulata comb. nov. , clavata euritmica heterocirra limbata longiarticulata neapolitana cf. nitidula –with comments regarding confidence some these records. also describe three new marielleae n. sp. nitiduloides based on material Fernando de Noronha Trindade islands, off Northeastern coast,...
Abstract The symbiotic relationship between the syllid polychaete, Haplosyllides floridana Augener, 1922, and barrel-shaped sponge Xestospongia muta (Schmidt, 1870), originally documented solely in Caribbean, is presumed to be species-specific. Recently, host has been found as a single species distributed across approximately 8000 km (from 26°N 22°S). Herein we addressed new spatial bathymetric population records of H. question persistence association with X . , whether, case an association,...
