Thermal stress is now considered the major recent cause of coral reef degradation; yet few studies have been conducted describing those effects on Southwestern Atlantic (SWA) reefs. The SWA represents a endemism hotspot with low-functional redundancy and therefore high extinction risk. Recent research has suggested “thermal refuge” potential for SWA; however, evidence could suggest different trend. We report herein an unprecedented mortality largest coastal Brazilian Marine Protected Area...
Free-living marine nematodes of continental shelf Portugal were studied through the goals Marine Biodiversity Information System Project (M@rbis 2015). Four species unknown to science and belonging families Axonolaimidae, Chromadoridae, Desmodoridae Xyalidae are described. Besides Hypodontolaimus golikovy, portuguese sp. n. is only in this genus which lacks precloacal supplements gubernaculum but differs from former mainly cephalic setae length amphidial fovea features. Metachromadora aliusa...
Abstract Mangroves are highly productive environments that play important ecological and socioeconomic roles; however, they have been impacted to different degrees in most countries worldwide. The knowledge of which organisms inhabit this environment their interactions is the first step towards its conservation. natural variability environmental factors mangroves provides numerous niches available species. Meiofauna patchy patterns distribution related availability resources. Hence,...
Abstract Invasive species are leading to ecosystem changes and socioeconomic deterioration around the globe. In 2018, unknown soft corals were noticed forming a massive ‘blue carpet’ on shallow reef environment at Todos os Santos Bay, South-west Atlantic. this study we identified species, quantified their distribution abundance as first step for baseline invasion monitoring, discussed origin, vector impacts native competitors. Coral samples based morphology multilocus DNA barcode, benthic...
Na região estuarina da Lagoa dos Patos, o siri-azul Callinectes sapidus Rathbun, 1869 é mais abundante dentre as espécies do gênero. Apesar exercer influência sobre comunidades bentônicas, por ser considerado um predador topo cadeia alimentar, não existem muitos estudos aspectos ecológicos, inclusive a composição e variabilidade sazonal de sua dieta natural, neste estuário. O objetivo principal deste estudo foi investigar siri-azul, evidenciando possíveis relações com comunidade bentônica...
Within a subtropical estuary in southern Brazil, an experiment was carried out to test the hypotheses that deposit feeding macrofaunal polychaete Laeonereis acuta affects nematode community structure and vertical distribution patterns of nematodes sediments. Inclusion cages were deployed with two different densities meiofaunal sampled from six sediment layers: 0–1, 1–2, 2–4, 4–6, 6–8 8–10 cm depth. Although L. did change both trophic groups sediment, allowing inhabit deeper layers, there no...
Abstract Here, we present results from a study conducted in two major shrimp fishing grounds the Northeastern Brazil Marine Ecoregion (NBME) that determined reproductive dynamics of penaeid shrimps Xiphopenaeus kroyeri and Penaeus schmitti . We aimed to verify if current closed season is appropriate untangle environmental drivers control their dynamics. The periods recruitment reproduction both species overlap significantly, with spawning peak taking place dry wet season. process seem be...
Oil pollution has significantly contributed to coral reef decline in the last five decades and a major oil spill reached Brazilian tropical coast August 2019. Here, we report first evidence of direct crude contact from that on species, evaluate effects this disaster vitality benthic assemblage structure largest coastal marine protected area (MPA Costa dos Corais) Brazil. We compared cover reefs with without monitored Siderastrea stellata colonies 90 days after contact. stains between 0.5 150...
Although, estuarine ecosystems have an ecological and economical importance as they a high biological productivity occur within unique dynamic environment, been subjected to anthropogenic alterations. The Great Vitória Estuarine System (GVES), Espírito Santo State, Brazil, is not exception, urbanization growing around it with quantity of sewage added the system. In order evaluate eutrophication state well meiofauna response it, several parameters in both sediments water column were assessed....
Abstract Aim The Brazilian tropical semiarid is a biome with small freshwater ecosystems, often intermittent, acting as mosaic in constant transformation between dry and rainy seasons. Meiobenthic communities play crucial roles these environments, understanding their colonization succession processes essential to comprehend how organisms’ structure defaunated habitat. In addition the traditional taxonomic approach, functional traits provide valuable insights into dynamics of processes. this...
A grandiosidade do rio Sao Francisco sempre despertou no ribeirinho a erronea ideia de que suas aguas seriam capazes absorver tudo o e descartado em aguas. Atualmente, despejo inadequado residuo solido um dos grandes problemas mundiais. presenca residuos solidos Baixo abordada utilizando tecnicas censos visuais mergulho livre.
