This list includes a chapter dedicated to marine mammals, based on previously published bibliography. No new species were added since that list was publlished. However, there were new occurrences since the last update.

The objective of the study was to perform a rapid biodiversity assessment, comparing the three sites in two different years, before and after the implementation of several conservation measures. This project also contributed to improve the knowledge of Azorean arthropod diversity at both local and regional scales, including new taxa for Terceira island and new records for Azores. Taking into consideration those aims, a set of standardised sampling methods were performed, inspired by the COBRA protocol originally developed for spiders. A total of 15,810 specimens belonging to 216 arthropo...

Most of those publications are difficult to access on line and several were not published in peer-reviewed journals. This checklist updates all the chondrichthyan records for the Azores Exclusive Economic Zone (EEZ), according to the most recent taxonomic classification of cartilaginous fish, as well as providing information on the conservation status for all species. We also present recent literature data on rare species and recent records for Azores. This is the first comprehensive list of cartilaginous fishes from Azores to be published in the GBIF database.

While there are relatively good data on their distribution in the western Atlantic, confirmed occurrences, population status, fishing reports, and trade data are almost non-existent for West Africa. Part of the problem is that tropical West African countries largely lack the wherewithal to fund the research needed to evaluate this species, nor do they have laws, management plans, or viable enforcement measures that might lead to effective population recovery or protection for essential juvenile mangrove habitats. Given the lack of published studies on this species in West Africa, the primary objectives of this paper are (1) to describe all known historical and current anecdotal information available on this species and (2) t...

Um dos raros grupos de ilhas que "escapou" mais tempo à invasão humana. Porém, essa fauna, tal como acontece em muitos outros casos de longa evolução isolada em ilhas (p. ex. Hawaii, Nova Zelândia, ilha de Natal, Galápagos ou mesmo a imensa Madagáscar), quando confrontada com pressões vindas de ecossistemas muito competitivos, pura e simplesmente não consegue sobreviver e tende a desaparecer rapidamente. Foi o que aconteceu neste canto do Índico.info:eu-repo/semantics/publishedVersio

Em face da literatura disponível alguns aspectos mais relevantes da etologia reprodutiva de E. marginatus como sejam as agregações reprodutivas e os locais de reprodução são debatidos. Foram amostrados 60 exemplares adultos, capturados na costa sul da ilha Terceira (Açores), aos quais se procedeu à sexagem com vista a inferir da estabilidade de uma população residente em termos de sex-ratio.ABSTRACT: In this paper we discuss the sex inversion process of a teleost fish from rocky shores, the dusky grouper Epinephelus marginatus Lowe, 1834. According to the available literature, some of the most relevant aspects of E. marginatus reproductive ethology, such as reproductive aggregations and reproduction sites, are debated. A sample of 60 adult specimens, captured in t...

Dados e observações levadas a cabo nos Açores e no Sul do Brasil permitem traçar um quadro provisório de interacções que evoluem com o processo ontogénico de ambas as espécies. Enquanto post-larvas e juvenis os meros aparentam um comportamento predatório muito generalista que incluem associações com alguns predadores nucleares entre os quais o polvocomum. Todavia, e à medida que crescem, os meros passam a integrar os polvos na sua dieta habitual sendo que esta importância atinge valores que nos permitem caracterizar o polvo como item principal na alimentação de meros com tamanhos superiores a 90 cm. Este ensaio está integrado num trabalho em curso desde há vários anos sobre a ecologia e biologia de E. marginatus numa perspectiva an...

The stomach contents of 245 specimens, collected between August 1997 and July 1999, were analysed. Decapod crustaceans and teleost fishes constitute the main food items, revealing a high level of specialization by S. maderensis. Ontogenic shifts and seasonal changes in the diet composition were observed, unveiling the adaptability and opportunistic predatory behaviour of this scorpaenid.RÉSUMÉ: Les habitudes alimentaires de Scorpaena maderensis Valenciennes, 1833 de l'archipel des Açores ont été étudiées.

João de Castro Bank in the Portuguese Azores Islands for diving and birdwatching on 9 October 2020, occupants of a rib boat from the Best Spot Azores Dive Center (São Miguel Island, Azores), spotted a sea turtle with a bird on top of its carapace, at a position halfway between Ponta dos Mosteiros on São Miguel Island and the bank (37.9676°N, 26.1671°W; Fig. 1). The bird was identified as a Common Tern (Sterna hirundo Linnaeus, 1758) and photos were taken.

The biology, behaviour and feeding ecology of this species is virtually unknown. Between 1997 and 1998, 100 individuals of S. viridensis were collected in the Azores islands. Their size ranged from 545 to 1190 mm (TL). Stomach contents were analysed and 66% of them contained food. Fish were the only prey observed. Juveniles of Trachurus picturatus were the dominant item identified, occurring in 82.2% of the stomachs containing food. Mean size of prey was correlated to the mean size of barracudas. Some 550 hours of behavioural observations were carried out. Different types of aggregations were observed with small groups and isolated individuals in winter conditions and big schools in summer, displaying several types of predatory behaviour.

There is no “one-size-fits-all” strategy, and a variety of disciplines and actors are needed for any counteractive approach to work effectively. Here, we detail common challenges faced when tackling IUWT, and we describe some available tools and technologies to curb and track IUWT (e.g. bans, quotas, protected areas, certification, captive-breeding and propagation, education and awareness). We discuss gaps to be filled in regulation, enforcement, engagement and knowledge about wildlife trade, and propose practical solutions to regulate and curb IUWT, paving the road for immediate action.

Studies on colonization events since early stages, establishment of new populations and range extension are scarce because of their rarity, difficult detection and monitoring. Chromis limbata is a reefassociated and non-migratory marine fish from the family Pomacentridae found in depths ranging between 3 and 45 m. The original distribution of the species encompassed exclusively the eastern Atlantic, including the Azores, Madeira and the Canary Islands. It is also commonly reported from West Africa between Senegal and Pointe Noire, Congo. In 2008, vagrant individuals of C. limbata were recorded off the east coast of Santa Catarina Island, South Brazil (27  41 0 44 00 S, 48  27 0 53 00 W). This study evaluated the increasing densities of C. limbata populations in Santa Catarina State shoreline. Two recent expansions, northwards to S~ ao Paulo State and southwards to Rio Grande do Sul State, are discussed, and a niche model of maximum entropy (MaxEnt) was performed to evaluate suitable C. limbata habitats. Brazilian populations are established and significantly increasing in most sites where the species has been detected. The distributional boundaries predicted by the model are clearly wider than their known range of occurrence, evidencing environmental suitability in both hemispheres f rom areas where the species still does not occur. Ecological processes such as competition, predation and specially habitat selectivity may regulate their populations and

We reviewed the recent study by Karkarey et al. (BMC Ecol 17:10, 2017) on the spawning behavior of Squaretail coralgrouper (Plectropomus areolatus) from India and found no evidence to support their findings of alternative reproductive tactics, unique school-spawning involving a single male with multiple females, or inverse size-assortment. The study lacks scientific credibility due to a lack of rigor in the methodology used, misinterpretation of observed behaviors, misinterpretation of the literature, and insufficient data. Their approach led the authors to produce spurious results and profound, invalid conclusions that violate the most basic assumptions of mate choice and sexual selection theory as applied to mating systems in marine fishes.
