  • Acusicola rochai n. sp. (Copepoda: Ergasilidae) parasitizing Anableps anableps (Anablepidae) from the Amazon Coast, with a key for Acusicola spp.
    João Victor Couto, Jorge Luiz Silva Nunes, Fabiano Paschoal, and Felipe Bisaggio Pereira

    Cambridge University Press (CUP)
    Abstract Ergasilid copepods represent one of the commonest groups of fish parasites in Brazil. Within Ergasilidae, three genera share a peculiar latching mechanism on the antenna that completely encircles the gill filament, one of which is Acusicola Cressey, 1970. During a survey of estuarine fish from the Brazilian Amazon Coast, a new species of Acusicola was found on the gills of the largescale foureyes Anableps anableps (Linnaeus, 1758) (Actinopterygii: Anablepidae) in São Marcos Bay, State of Maranhão. Acusicola rochai n. sp. can be distinguished from its closest congeners mainly by three protrusions on the dorsal surface of third and fourth pedigerous somites, and by smooth interpodal plates. This work is the first report of a parasitic copepod infesting a fish from Anablepidae and, consequently, the host An. anableps. The existing dichotomous key proposed for the genus Acusicola includes only ten species, excluding the eight species subsequently described. Therefore, in the present work, a new dichotomous key is provided based on reliable and well-documented features.

    Abstract Mobulid rays are medium‐ to large‐sized pelagic‐dwelling planktivorous elasmobranchs that are circumglobally distributed. Brazil has a high diversity of Mobula species, with five of the nine globally valid species and one additional putative new species. Brazil represents a substantial knowledge gap concerning the ecology, distribution and threats to mobulid rays. In global distribution analyses, several species have been underrepresented along the Brazilian coast. The dataset is composed of information from peer‐reviewed and grey literature, as well as data from scientific expeditions, citizen science collaboration, social media and local news. We found 6,450 records of manta and devil rays along the Brazilian coast, including Mobula tarapacana, Mobula mobular, Mobula thurstoni, Mobula hypostoma, Mobula birostris and the putative new species (Mobula cf. birostris). Our results revealed alarmingly high captures, such as 4.5 tons of M. hypostoma in a single fishery cruise and 809 individuals of Mobula spp. from a single fleet during one year in the Southeastern region. These findings evidence the fisheries' threats to mobulid species in Brazil and highlight previously unnoted species records, such as the occurrence of M. hypostoma on the entire Brazilian continental shelf, including estuaries and M. tarapacana in coastal regions. Integrative information on the occurrence, distribution, and threats to mobulid rays on local and global scales is crucial to supporting strategies for their effective management and conservation.

    AbstractLittle is known about the ecology and distribution of mobulid rays along Brazil's extensive coastline. Here we report opportunistic sightings of manta rays (Mobula cf. birostris) in the Brazilian Amazon estuaries and the Great Amazon Reef System. These sightings consist of manta ray individuals stranded in tide pools, caught in artisanal fisheries, and footage obtained with a submersible. Future investigations on the spatial, temporal, and environmental drivers of manta rays' distribution on the northern Brazilian coast and the threats posed by fishing gear are warranted.

    Abstract Sharks of the genus Sphyrna are under intense exploitation globally. In Brazil’s northern coast, this genus represents a high proportion of fisheries landings and comprises four species. However, due to difficulty of specific identification when specimens are landed, most of the records are limited to the genus level. Here we analyzed the effectiveness of ITS2 (Internal Transcribed Spacer 2 of rDNA) fragment length protocol (Abercrombie et al., 2005) for identifying hammerhead shark species, comparing with the analysis of COI (Cytochrome oxidase subunit I) and ITS2 sequences. We evaluated samples of muscle tissue acquired in the main fishing ports of Maranhão: Carutapera, Raposa e Tutóia. Sampling was conducted between March 2017 to March 2018 and complemented with material deposited in collection (2015). COI results indicated the occurrence of endangered species which are prohibited to be landed. These include Sphyrna mokarran (67%), S. lewini (15%), S. tudes (3%), and S. tiburo (15%). For the ITS2 marker, we investigated the optimization of the protocol developed by Abercrombie (2005) for to improve the use in this geographical area througout design of a new primers.

Despite ongoing research efforts, the ichthyofauna of the coastal basins of Maranhão State, Brazil remains poorly described (Abreu et al., 2019). In recent years the number of research publications on fish diversity in this region has increased (e. g. Brito et al., 2019; Guimarães et al., 2020; Oliveira et al., 2020), however important work remains to be done. An accurate assessment of population parameters related to fish reproduction is an essential component of effective fisheries management (Brown‐Peterson et al., 2011; Nascimento et al., 2015; Nunes et al., 2019). The Baixada Maranhense Environmental Protection Area is a RAMSAR site consisting of a complex ecosystem in which human beings play an essential role in managing, using, and conserving several components. Due to the abundance of regional water resources, fishing is among the most important socioeconomic activities (Araujo and Pinheiro, 2008). In recent decades this region has undergone substantial anthropogenic changes, decreased river water flow, siltation, damming, and other anthropic activities compounded by changes in rainfall patterns (Cantanhêde et al., 2017). Monitoring the ichthyofauna in rivers is essential to identify environmental responses to human actions and provides subsidies to regulate the use of water resources, thus enabling the development of alternatives to minimize river degradation (Santos et al., 2017; Lima et al., 2018). This study describes the minimum size at first maturation (L50) of commercially important fish species in two distinct habitats (a river and a lake) within the Pindaré River Hydrographic Basin. We use data from monthly collections that were carried out for 18 months (January 2015 to June 2016), in Lake Viana and the Pindaré river in the state of Maranhão, in northeastern Brazil. The study area is a designated RAMSAR Site, protected by Brazil under the RAMSAR intergovernmental treaty (Brasil, 2010). It is characterized by seasonal changes in rainfall that influence both the reproductive behavior and adaptations of fish species and the dynamics of the local fishing industry. When there is a shortage of fish stocks, extractive activity is intensified to meet demand, and the seasonal reduction in floods that occur annually triggers annual overfishing (Carvalho et al., 2017; Carvalho et al., 2021). We purchased specimens used for this work from local fish markets, then stored them on ice for transport to the laboratory, where they were subsequently identified to the lowest possible taxonomic level. We then analyzed all specimens morphologically to assess total length (TL) and total weight (TW) with the aid of an ichthyometer and an electronic caliper with a precision of 1 mm and 0.01 g, respectively. Then we made a longitudinal incision on the ventral portion of each specimen to remove the gonads. We then fixed the gonads in a 5% formalin solution for subsequent preservation in 70% ethanol. We deposited all specimens in the Collection of tissues and DNA of the fauna of Maranhão, UEMA (CoFauMA), and in the teaching collection of fishes of the Laboratory of Fisheries and Aquatic Ecology, UEMA (LabPEA). We assessed the reproductive state for each specimen through macroscopic identification of the stage of gonadal maturation and characterization of the gonads according to the scale proposed by Brown‐Peterson et al. (2011) and Lowerre-Barbieri et al. (2011). We calculated minimum size at first maturation (L50) based on the cumulative curve of occurrence frequencies of adult individuals by total length class adjusted to the logistic function. We characterized the maturation as A (immature); B (under development); C (able to spawn); D (regressing), and E (regenerated). We calculated the percentage of adult organisms (stages B, C, D, and E) by length class and considered as a dependent variable (Y) and the total length as an independent variable (X). Subsequently, we fitted these values to a logistic curve, using the Statistica 7 Program according to the following formula: P = 1/(1+exp[-r (L – Lm)]). P is the proportion Length at first sexual maturity of the freshwater fish fauna of the Baixada Maranhense Environmental Protection Area

  • Revisiting the debate: documenting biodiversity in the age of digital and artificially generated images

    Abstract. This study examines the risks associated with relying solely on images for documenting new species records, rediscoveries, taxonomic descriptions, and distribution expansions. We highlight concerns regarding image authenticity, especially in cases where images may be altered, adulterated, or AI (artificial intelligence)-generated, potentially leading to inaccuracies in biodiversity documentation. To illustrate the evolving challenges, we conducted an experiment with 621 participants who assessed nine AI-generated images. Surprisingly, six were deemed authentic, while three raised doubts, highlighting the difficulty in discerning AI-generated content. Our main message emphasizes the critical role of trust in biodiversity documentation, particularly for taxonomy and conservation, and how eroded trust can hinder conservation efforts. Improved communication and collaboration between taxonomists and conservationists are needed, emphasizing scientific integrity. We urge a reevaluation of journal policies concerning data validation, especially in articles relying on images as primary evidence, to preserve the credibility of scientific research amidst technological advancements.

  • Unveiling the Threats Beneath: Fish Mislabeling in the Brazilian Amazon Coast and its Impacts on the Critically Endangered Daggernose Shark
    Natascha Wosnick, Patricia Charvet, Rachel Ann Hauser‐Davis, Getulio Rincon, Ana Rita Onodera Palmeira Nunes, and Jorge Luiz Silva Nunes

    Wiley
    AbstractFish mislabeling is a global issue with far‐reaching consequences for both food security and biodiversity conservation. This practice involves the intentional or unintentional misidentification of fish species sold in markets and restaurants, often driven by economic gain or cultural preferences. The mislabeling of threatened fish species further exacerbates the problem. This manuscript focuses on an emerging mislabeling practice in the Brazilian Amazon coast, which impacts a critically endangered elasmobranch species, the Daggernose Shark Isogomphodon oxyrhynchus. More specifically, the mislabeling of the Atlantic Tripletail Lobotes surinamensis as the Acoupa Weakfish Cynoscion acoupa has led to intensified fishing activities and incidental capture of the Daggernose Shark. Traditional enforcement approaches have shown limited effectiveness, and alternative conservation interventions, including participatory management and education programs for artisanal fishers, are needed to address this complex issue.

  • Assessment of the physiological vulnerability of the endemic and critically endangered Daggernose Shark: A comparative approach to other Carcharhiniformes
    Natascha Wosnick, Ana Paula Chaves, Héllida Negrão Dias, Ana Rita Onodera Palmeira Nunes, Jorge Luiz Silva Nunes, and Rachel Ann Hauser-Davis

    Frontiers Media SA
    IntroductionThe current Isogomphodon oxyrhynchus (Daggernose Shark) population status Q7points to 99% losses in the last decade due to certain biological traits, site fidelity, and historical high representativeness as bycatch in artisanal fisheries. This species is listed as Critically Endangered (CR), both in the IUCN and the Brazilian Red Lists. Its vulnerability is so high that its recovery potential requires protection from ongoing fishing pressure.ObjectiveIn this context, this study aimed to evaluate the health status of Daggernose sharks and their ability to cope with allostatic overload in a comparative analysis with other Carcharhinid and Sphyrnid sharks.MethodsSharks incidentally caught by the artisanal fleet in the state of Maranhão, on the Brazilian Amazon Coast, were sampled for blood, and serum was used to assess biochemical markers.ResultsThe findings indicate significant differences in Daggernose Shark homeostatic capacity for ALP, ALT/GTP, creatinine, lactate, urea, total cholesterol, and triglycerides, pointing to lower health scores and recovery capacity when compared to other Carcharhiniformes inhabiting the same region.Discussion and conclusionsIt is possible that such vulnerability is a result of fisheries-induced evolution, leading to remaining populations with very low chances of fully recovering. Conservation planning is thus urgent, as current legislation based on fishing bans does very little for the species. International collaboration and longterm recovery measures are necessary, including the creation of MPAs specially designed for the species and captive maintenance aiming to monitor health status and carry out breeding attempts.

  • Potential negative effects of the Brazilian Space Program on coastal sharks

    The Brazilian government recently announced its first partnerships with the private sector, including American and Canadian companies, to use the Alcântara Space Center (Maranhão, northern Brazil). This center is known for its privileged location, saving up to 30% of fuel in launches. Its operationalization is an offshoot of the Technological Safeguards Agreement, which is important for the Brazilian Space Program due to greater space sector investments and environmentally relevant projects. In 2003, a major fire at the Alcântara Space Center destroyed a rocket and killed 21 workers, halting Brazilian Space Program activities. Recently, our research group reported serious environmental consequences of this accident, i.e., extremely high amounts of Rubidium (Rb) in apex predatory sharks near the Alcântara Space Center. This element is used in fuels and in space propulsion systems and is potentially toxic, displaying bioaccumulating and biomagnifying capabilities. The observed concentrations are the highest ever detected in any living organism (up to 24.65 mg kg-1 dry weight). The launch base is located on the Brazilian Amazon Coast, and population recruitment impacts may compromise biota conservation and biodiversity. Local shark meat consumption is also worrying, as consumers may be exposed to Rb, whose effects in humans are unknown. We, therefore, indicate an urgent need for biomonitoring efforts in the area, as the Alcântara Space Center is about to operate at its maximum capacity.

  • Evolutionary History and Taxonomic Reclassification of the Critically Endangered Daggernose Shark, a Species Endemic to the Western Atlantic

    The family Carcharhinidae includes the most typical and recognizable sharks, although its internal classification is the subject of extensive debate. In particular, the type genus, Carcharhinus Blainville, 1816, which is also the most speciose, appears to be paraphyletic in relation to a number of morphologically distinct taxa. Isogomphodon oxyrhynchus (Valenciennes, 1839) (the daggernose shark) is a carcharinid, which is endemic to a limited area of the Western Atlantic between Trinidad and Tobago and the Gulf of Maranhão in northern Brazil, one of the smallest ranges of any New World elasmobranch species. In recent decades, I. oxyrhynchus populations have been decimated by anthropogenic impacts, which has led to the classification of the species as critically endangered by the IUCN. However, there is considerable debate on both the validity of the species (I. oxyrhynchus) and the status of Isogomphodon Gill, 1862 as a distinct entity from the genus Carcharhinus. The present study is based on a molecular assessment of the genetic validity of the I. oxyrhynchus that combines mitochondrial and nuclear markers, which were used to identify the biogeographic events responsible for the emergence and dispersal of the species in northern Brazil. The genetic distance analyses and phylogenetic trees confirmed the paraphyly of the genus Carcharhinus, recovering a clade comprising Carcharhinus+I. oxyrhynchus+Prionace glauca (Linnaeus, 1758). Our results indicate not only that the daggernose shark is actually a member of the genus Carcharhinus, but that it is genetically more closely related to Carcharhinus porosus (Ranzani, 1839) than it is to the other Carcharhinus species analyzed. Given this, I. oxyrhynchus and P. glauca are therefore reclassified and recognized as Carcharhinus oxyrhynchus and Carcharhinus glaucus. The daggernose shark, Carcharhinus oxyrhynchus, diverged from C. porosus during the Miocene, when significant geomorphological processes occurred on the northern coast of South America, in particular in relation to the configuration of the Amazon River. It is closely associated with the area of the Amazon plume, and its distinctive morphological features represent autapomorphic ecological adaptations to this unique habitat and do not reflect systematic distinction from Carcharhinus.

    AbstractOmobranchus punctatus is native to the Indo-Pacific region and invasive in the Atlantic region, currently being considered one of the most widely distributed blenny species. However, recent molecular studies indicated that O. punctatus is a complex of species, with three divergent mtDNA lineages identified to date, stressing the need for a taxonomic revision. In this study, we used an integrative approach, combining morphological and genetic data, to shed light on the taxonomy and distribution of O. punctatus. Moreover, we provide the first genetic records of introduced populations in Brazil and discuss the introduction pattern of this species in this region. Morphological data shows that O. punctatus consists of at least five distinct and geographically restricted species: O. punctatus sensu stricto, O. dispar, O. sewalli, O. cf. kochi, and O. cf. japonicus. Species delimitation analyses performed using the mtDNA data available confirmed that O. punctatus sensu stricto, O. dispar and O. sewalli correspond to different species that started to diverge about 2.6 Mya. Furthermore, O. sewalli was identified as the invasive species colonizing Atlantic shores. The existence of historical oceanographic barriers, such as the emergence of the Sunda Shelf in the Eastern Indian Ocean during the Pleistocene, and the biological traits of these blennies are the most likely factors responsible for their genetic differentiation and subsequent speciation.

  • Elasmobranch-associated microbiota: a scientometric literature review

    PeerJ
    Elasmobranchs provide greatly relevant ecosystem services for the balance of the environments in which they are inserted. In recent decades, sharp population declines have been reported for many species in different regions worldwide, making this taxonomic group currently one of the most threatened with extinction. This scenario is almost entirely due to excessive fishing pressure, but any contributing factor that may cause additional mortality to populations must be mapped and monitored. In a fast-changing world, emerging marine pollution associated with climate change display the potential to increase the spread of infectious agents. These can, in turn, lead to mortality events, both directly and indirectly, by reducing immune responses and the physical and nutritional condition of affected individuals. In this context, the present study aimed to analyze data concerning elasmobranch-associated microbiota, identifying study trends and knowledge gaps in order to direct future studies on this topic of growing relevance for the health of wild populations, as well as individuals maintained in captivity, considering the zoonotic potential of these microorganisms.

    Resumo Realizou-se um estudo transversal para estimar a prevalência de abortamento espontâneo em 360 mulheres distribuídas em área de maior e menor exposição à poluição atmosférica proveniente do tráfego de veículos na Ilha de São Luís-MA e identificação de variáveis associadas. As participantes foram entrevistadas e os dados coletados foram submetidos à regressão logística bivariada e multivariada. A prevalência geral de aborto espontâneo foi 15,83%, correspondendo a 25,56% (n=180) na área de maior exposição e 6,11% (n=180) na área de menor exposição. Associaram-se ao aborto espontâneo o etilismo materno (OR=3,11), a presença de IST na gestação (OR=2,74), viver na área de alta exposição (OR=8,32), ter sofrido violência física ou psicológica na gestação (OR=4,25) e a ocorrência de abortamento de repetição (OR=39,11). Os resultados apontam para uma possível contribuição da poluição do ar proveniente do tráfego de veículos como fator de risco na etiologia do aborto espontâneo.

    It is widely recognized that apex predators, such as large sharks with highly migratory behavior, are particularly vulnerable to pollution, mainly due to biomagnification processes. However, in highly impacted areas, mesopredator sharks with resident behavior can be as vulnerable as apex sharks. In this context, this study evaluated cadmium (Cd), mercury (Hg), lead (Pb), and rubidium (Rb) concentrations, as well as the potentially protective effects of selenium (Se) and the behavior of two non-enzymatic biomarkers, metallothionein (MT) and reduced glutathione (GSH), employing the Atlantic nurse shark Ginglymostoma cirratum as a study model and compared the results with other resident benthic sharks, as well as highly mobile apex sharks. Muscle tissue samples from 28 nurse sharks opportunistically sampled from the Brazilian Amazon Coast were analyzed. Lower metal concentrations were observed for Pb, Rb and Se in the rainy season, while statistically significant correlations between metals were observed only between Hg and Cd and Pb and Se. Molar ratio calculations indicate potential protective Se effects against Pb, but not against Cd and Hg. No associations between MT and the determined metals were observed, indicating a lack of detoxification processes via the MT detoxification route. The same was noted for GSH, indicating no induction of this primary cellular antioxidant defense. Our results indicate that benthic/mesopredator sharks with resident behavior are, in fact, as impacted as highly mobile apex predators, with the traditional detoxification pathways seemingly inefficient for the investigated species. Moreover, considering the studied population and other literature data, pollution should be listed as a threat to the species in future risk assessments.
