In August 2019, the Brazilian Northeast coast was hit by largest environmental disaster caused oil spill (petroleum) in its history, with first record (30th) Paraíba 1 .Since then, leak has spread to over 70% of 3,300 kilometers other northeastern states, reaching almost 500 locations early November 2 .Until late November, assumptions regarding source have not yet been confirmed government.According Santos et al. 3 , major offshore hydrocarbon transportation routes pass reef...
Abstract Coral reefs harbor one of the largest fish biodiversity on earth; yet information reef fishes is still absent for many regions. We analyzed richness, distribution, and conservation Brazilian multiple use coastal MPA; which cover a large extent coral at SWA. A total 325 species have been listed MPA Costa dos Corais, including Chondrichthyes (28 species) Actinopterygii (297). Fish were represented by 81 families most representative Carangidae (23 species), Labridae (21) Gobiidae (15)....
This paper provides a case study of threatened seahorse species, Hippocampus reidi, highlighting the importance using ecological information to assist conservation and management initiatives. Underwater visual sighting data (50 x 2m transect) gathered along NE, SE S portions Brazilian coast revealed an unequal distribution across localities, perhaps related harvesting pressure, mean density 0.026 ind.m-2. Our findings suggest some restricted spatial use by H. which was consistent with its...
Renewable energy sources are increasing globally, mainly due to efforts achieve net zero emissions. In Brazil, solar photovoltaic electricity generation has grown substantially in recent years, with the installed capacity rising from 2455 MW 2018 47,033 August 2024. However, intermittency of increases challenges forecasting generation, making it more difficult for decision-makers plan flexible and efficient distribution systems. addition, forecast power support grid expansion, is essential...
O presente estudo avaliou: 1) se a diversidade da ictiofauna de águas rasas do Rio Formoso (Pernambuco) varia entre as zonas estuarinas superior e inferior, os períodos seco chuvoso 2) houve diferenças espaciais temporais nas categorias tróficas dessa ictiofauna. Os peixes foram coletados bimestralmente com rede-de-arrasto tipo mangote. Foram 5475 indivíduos pertencentes 78 espécies, sendo 51,3% origem recifal. Carangidae Gerreidae tiveram maior riqueza específica, enquanto Clupeidae,...
We estimated the abundance of Antillean manatees ( Trichechus manatus ) through a large-scale project conducted in 2010 north-eastern Brazil and evaluated efficacy an aerial survey for conservation purposes. Two observers via flights that maintained altitude 150 m air speed 140 km h −1 , covering over 2590.2 2 coastline. Strip transects were flown zigzag pattern. A total 67 (on- off-effort) recorded 55 sightings. Historical published records occurrence formally incorporated using Bayesian...
Although the practice of recreational feeding fish by tourists is widespread within marine protected areas (MPAs), ecological consequences this activity have received little attention. This research aimed to investigate influence artificial on reef communities two Brazilian MPAs. Visual censuses were performed in not visited tourists, order characterize natural community structure each system. In Maracajaú reefs, effect was assessed below a moored floating dock found area. Stationary visual...
The branching structure of the coral colonies from genus Millepora provides substrate, shelter, and food resources for several reef organisms, such as fish invertebrates. present work analysed association behaviour on fire alcicornis M. brasiliensis September 2010 to February 2011, coastal reefs Tamandaré, north-east Brazil. A total 473 individuals 27 species were sighted associated with colonies, mainly composed juveniles (65%). most frequently observed behaviours sheltered/stationary...
The objectives of the present study were to identify species reef fish that use Rio Formoso estuary (northeastern Brazil) as a refuge and natural nursery describe spatial distribution fauna in rainy dry seasons. A total 5475 specimens, across 78 39 families, analyzed; 51.3% origin. Among these, Eucinostomus melanopterus (Bleeker, 1863), E. gula (Cuvier, 1830), Sphoeroides testudineus (Linnaeus, 1758), this order, most abundant upper estuary; S. greeleyi Gilbert, 1900, melanopterus, Lutjanus...
This study compared tidepool fish assemblages within and among habitats at Iparana Pecém beaches, State of Ceará, Northeast Brazil, using visual census techniques. A total 8,914 fishes, representing 25 families 43 species were recorded. The most abundant taxon was Sparisoma spp, followed by Haemulon parra (Desmarest, 1823), Acanthurus chirurgus (Bloch, 1787) Abudefduf saxatilis (Linnaeus, 1758). Haemulidae the family in number individuals, Scaridae, Acanthuridae Pomacentridae. Within-...
O presente estudo teve como objetivos identificar e caracterizar os principais fatores fisiográficos das áreas estuarinas em Pernambuco, assim as ações antrópicas por elas sofridas; listar peixes que vivem nesses estuários, atualizando validações dos nomes científicos espécies; analisar a distribuição registros de ocorrência espécies estuário. Os dados para análise estuários foram baseados três trabalhos sobre Pernambuco. As informações ictiofauna obtidas partir 25 monografias, dissertações,...
The high diversity and distribution of Bathygobius Bleeker, 1878 makes it an excellent group to study evolution patterns within the Atlantic. Thus, aims this work were investigate taxonomic status, geographical evolutionary history in Atlantic examine genetic structure demographic phylogeographic two species widely distributed Atlantic, soporator geminatus. Our results indicate that a new insular species, brasiliensis sp. nov., can be found Western which diverged from its sister...
The prawn fishery produces more discards than any other type of catch and captures a large quantity immature individuals. This research aimed to assess the sustainability capture fish bycatch in trawling. Each species was assessed according two groups criteria: (1) their relative vulnerability by trawl mortality due this (2) recovery capacity specie after possible collapse population. Within each group, ranked (1-3), being 1 highest value, meaning is highly susceptible or has low resilience....
Abstract Although underwater visual census ( UVC ) is the most frequently used technique for quantifying reef fish assemblages, remote video analysis has been gaining attention as a potential alternative. In South Atlantic Ocean, Millepora spp. (class Hydrozoa) are only branching coral species; however, little known about ecological role that they play communities. We compared these two observation methods (remote and to estimate abundance species richness associated with colonies of...
Data on Sotalia guianensis Van Bénéden, 1864 occurrence the beaches of Pernambuco (Northeastern Brazil) is restricted to information stranding and printed material from local newspapers; actual observations such animals have not been published. This study intends determine use habitat, behavioral activities assess relationships between environmental factors recorded behavior. Observations were conducted open sea coastal areas, Olinda Piedade, as well in sheltered ports Recife Suape....
The genus Achirus is made up of demersal fish that have a close relationship with the substrate and exhibit peculiar aspects during their larval stage. aim present study was to determine whether abundance larvae differed among set habitats in estuary Formoso River State Pernambuco (north-eastern Brazil). Sampling performed monthly between April 2009 March 2010, comprised horizontal hauls plankton net day night mangrove, beach reef habitats. Fish were sorted, identified, measured stage...
New information about the effects of seismic surveys on cetaceans is causing increasing concern impact this type activity marine life. The described include behavioral responses and changes in vocalization patterns, diversion migratory routes, damage to auditory system, an increase strandings. Although such could affect diversity species areas where research has been carried out, there no scientific subject. This study aims evaluate relationship between surveys, oceanographic data recorded...
