  2. Asymmetrical dispersal and putative isolation-by-distance of an intertidal blenniid across the atlantic–mediterranean divide

    Castilho, Rita; Cunha, Regina L.; Faria, Cláudia Barreiros Macedo de; Velasco, Eva Maria; Robalo, Joana Isabel
    Transition zones are of high evolutionary interest because unique patterns of spatial variation are often retained. Here, we investigated the phylogeography of the peacock blenny, Salaria pavo, a small marine intertidal fish that inhabits rocky habitats of the Mediterranean and the adjacent Atlantic Ocean. We screened 170 individuals using mitochondrial and nuclear sequence data from eight locations. Four models of genetic structure were tested: panmixia, isolation-by-distance, secondary contact and phylogeographic break. Results indicated clear asymmetric migration from the Mediterranean to the Atlantic but only marginally supported the isolation-by-distance model. Additionally, the species displays an imprint of demographic expansion compatible with...

  3. Identification of adult and juvenile Atherina presbyter Cuvier, 1829 in a marine coastal area adjacent to Tagus estuary (NE Atlantic): A molecular tool for an ecological question

    Almada, Frederico; Carpi, Piera; Carlos, Fábio Ferreira; Francisco, Sara Martins; Faria, Ana Margarida; Lungu, Ruxanda; Coelho, Pedro Duarte; Neto, José; Gonçalves, Emanuel João; Robalo, Joana Isabel
    A simple PCR-RFLP consisting in the digestion of a fragment of the 12S ribosomal RNA (12SrRNA) with species-specific restriction enzymes (MboII and HinfI) was developed to distinguish northeastern Atlantic species in the genus Atherina. Unambiguous identification of morphologically similar sympatric species is frequently difficult, especially when younger specimens are included in the analysis. Genetic and morphological analysis of a total of 123 atherinids collected near the mouth of the Tagus estuary (west Portugal) confirmed that only Atherina presbyter (sand smelt) adults and juveniles are recurrently using these marine rocky habitats as spawning and nursery grounds, respectively. The importance of applying non-destructive methods is emphasized. In the future, the conditions involved in the...

  4. Whistle stability and variation in captive bottlenose dolphins (Tursiops truncatus) recorded in isolation and social contexts

    Lopes, Patrícia Rachinas; Luís, Ana Rita; Borges, Ana Sofia; Neto, Márcia P.; Santos, Manuel Eduardo dos
    Common bottlenose dolphins (Tursiops trunca-tus) produce a range of underwater vocalizations, both pulsed (echolocation clicks and burst-pulses) and nonpulsed (whistles). Whistles may be emit-ted in stereotyped (signature) or variant patterns, and their production might be affected by sex, age, environmental, and social contexts. This study examined, non-intrusively, the whistle emissions of six captive bottlenose dolphins at Zoomarine in Algarve, Portugal, in two separate time sets and three different contexts: two of the animals in isolation in 2008, and all six in 2012, both seg-regated from their group and in social context. From a total of 1,681 whistles, 1,249 were ana-lyzed...

  5. Benthic food webs support the production of sympatric flatfish larvae in estuarine nursery habitat

    Dias, Ester; Morais, Pedro; Faria, Ana Margarida; Antunes, Carlos; Hoffman, Joel C.
    Identifying nursery habitats is of paramount importance to define proper management and conservation strategies for flatfish species. Flatfish nursery studies usually report upon habitat occupation, but few attempted to quantify the importance of those habitats to larvae development. The reliance of two sympatric flatfish species larvae, the European flounder Platichthys flesus and the common sole Solea solea, on the estuarine food web (benthic versus pelagic), was determined through carbon and nitrogen stable isotope analysis. The organic matter sources supporting the production of P. flesus and S. solea larvae biomass originates chiefly in the benthic food web. However, these species have significantly different d13C and d15N values which suggest that they prey on organisms that use...

  7. A regulation-based classification system for marine protected areas: A response to Dudley et al. [9]

    Costa, Barbara Horta e; Claudet, Joachim; Franco, Gustavo; Erzini, Karim; Caro, Anthony; Gonçalves, Emanuel João
    Dudley et al. [9] commented on our paper [11], arguing that the current IUCN objective-based categorization of protected areas, which is also used in marine protected areas (MPAs), should not be abandoned and replaced by the new regulation-based classification system [11]. Here we clarify that we do not advocate replacing the current IUCN categories, but highlight the benefits of using both the objective-based IUCN categories and the new regulation-based classification when applied to MPAs. With an increasing number of MPA types being implemented, most of them multiple-use areas zoned for various purposes, assessing ecological and socioeconomic benefits is key for advancing conservation targets and policy objectives....

  8. Larval development and allometric growth of the black-faced blenny Tripterygion delaisi

    Solomon, F. N.; Rodrigues, Diana; Gonçalves, Emanuel João; Serrão, Ester A.; Borges, Rita Alexandra
    Larval development and allometric growth patterns of the black-faced blenny Tripterygion delaisi are described from a larval series (body length, LB  = 3·30-12·10 mm) caught by light traps at the Arrábida Marine Park, Portugal. Larvae of T. delaisi possess distinctive morphometric and meristic characteristics which can be used to identify this species from related taxa. Pigmentation is sparse but characteristic, consisting of pigmented eyes, gas bladder pigmentation in the dorsal region, anal pigmentation and a row of regularly spaced postanal ventral melanophores. This pattern is present from as early as the yolk-sac stage and persists throughout all stages with just the addition...

  9. Three new Batillipes species (Arthrotardigrada: Batillipedidae) from the brazilian coast

    Santos, Erika; Rocha, Clélia M. C. da; Gomes, Edivaldo Júnior; Fontoura, Paulo
    Three new tardigrade species, Batillipes brasiliensis sp. nov., Batillipes dandarae sp. nov. and Batillipes potiguarensis sp. nov., are described from shallow subtidal sediments of the Brazilian coast. B. brasiliensis sp. nov. and B. dandarae sp. nov. have toes 3 and 4 on leg IV different in length, so they can be included in the D group of species, while B. potiguarensis sp. nov., with toes 3 and 4 on leg IV equal in length belong to the A group. Batillipes brasiliensis sp. nov. is characterized by having an ala-like caudal expansion; cuticular projections on the coxal region of legs I-III, and lateral projections. The lateral...

  10. Painted Goby Larvae under high-CO2 fail to recognize reef sounds

    Castro, Joana M.; Amorim, Maria Clara Pessoa; Oliveira, Ana P.; Gonçalves, Emanuel João; Munday, Philip L.; Simpson, Stephen D.; Faria, Ana Margarida
    Atmospheric CO2 levels have been increasing at an unprecedented rate due to anthropogenic activity. Consequently, ocean pCO2 is increasing and pH decreasing, affecting marine life, including fish. For many coastal marine fishes, selection of the adult habitat occurs at the end of the pelagic larval phase. Fish larvae use a range of sensory cues, including sound, for locating settlement habitat. This study tested the effect of elevated CO2 on the ability of settlement-stage temperate fish to use auditory cues from adult coastal reef habitats. Wild late larval stages of painted goby (Pomatoschistus pictus) were exposed to control pCO2 (532 μatm,...

  11. Novel insights into the dynamics of green turtle fibropapillomatosis

    Patrício, Ana R.; Diez, Carlos E.; Dam, Robert P. van; Godley, Brendan J.
    Outbreaks of fibropapillomatosis (FP), a neoplastic infectious disease of marine turtles, have occurred worldwide since the 1980s. Its most likely aetiological agent is a virus, but disease expression depends on external factors, typically associated with altered environments. The scarcity of robust long-term data on disease prevalence has limited interpretations on the impacts of FP on turtle populations. Here we model the dynamics of FP at 2 green turtle foraging aggregations in Puerto Rico, through 18 yr of capture-mark-recapture data (1997−2014). We observed spatiotemporal variation in FP prevalence, potentially modulated via individual site-fidelity. FP ex pression was residency dependent, and FP-free individuals developed tumours after 1.8 ± 0.8...

  12. High interannual variability in connectivity and genetic pool of a temperate clingfish matches oceanographic transport predictions

    Klein, Maria; Teixeira, Sara; Assis, Jorge; Serrão, Ester A.; Gonçalves, Emanuel João; Borges, Rita Alexandra
    Adults of most marine benthic and demersal fish are site-attached, with the dispersal of their larval stages ensuring connectivity among populations. In this study we aimed to infer spatial and temporal variation in population connectivity and dispersal of a marine fish species, using genetic tools and comparing these with oceanographic transport. We focused on an intertidal rocky reef fish species, the shore clingfish Lepadogaster lepadogaster, along the southwest Iberian Peninsula, in 2011 and 2012. We predicted high levels of self-recruitment and distinct populations, due to short pelagic larval duration and because all its developmental stages have previously been found near...

  13. White-faced storm-petrels Pelagodroma marina predated by gulls as biological monitors of plastic pollution in the pelagic subtropical northeast atlantic

    Furtado, Ricardo Miranda; Menezes, Dilia; Santos, Carolina Jardim; Catry, Paulo
    Marine plastic pollution is rapidly growing and is a source of major concern. Seabirds often ingest plastic debris and are increasingly used as biological monitors of plastic pollution. However, virtually no studies have assessed plastics in seabirds in the deep subtropical North Atlantic. We investigated whether remains of white-faced storm-petrels (WFSP) present in gull pellets could be used for biomonitoring. We analysed 263 pellets and 79.0% of these contained plastic debris originating in the digestive tract of WFSP. Pellets with no bird prey did not contain plastics. Most debris were fragments (83.6%) with fewer plastic pellets (8.2%). Light-coloured plastics predominated...

  14. At odds with the group: Changes in lateralization and escape performance reveal conformity and conflict in fish schools

    Chivers, Douglas P.; McCormick, Mark I.; Allan, Bridie J. M.; Mitchell, Matthew D.; Gonçalves, Emanuel João; Bryshun, Reid; Ferrari, Maud C. O.
    Many vertebrates are known to show behavioural lateralization, whereby they differentially use one side of their body or either of their bilateral organs or limbs. Behavioural lateralization often manifests in a turning bias in fishes, with some individuals showing a left bias and others a right bias. Such biases could be the source of considerable conflict in fish schools given that there may be considerable social pressure to conform to the group to maintain effective group evasion. Here, we show that predation pressure is a major determinant of the degree of lateralization, both in a relative and absolute sense, in...

  15. Feeding ecology and life-history strategy of nesting males in a fish with long parental care, Lusitanian toadfish (Halobatrachus didactylus, Batrachoididae)

    Félix, Pedro M.; Amorim, Maria Clara Pessoa; Pereira, Tadeu José; Fonseca, Paulo Jorge; Santos, Carla Sousa; Costa, José Lino
    The Lusitanian toadfish, Halobatrachus didactylus, like other batrachoidids, is a benthic fish species with nesting behaviour during the breeding season. During this prolonged period it engages in mating activities and remains in the nest providing parental care. It is not known whether males feed while providing parental care but it is likely that their limited mobility may restrict their diet and influence their fitness. As a consequence, egg cannibalism could occur as a life-history strategy. The aim of the present study is to ascertain the feeding behaviour of nesting males, in comparison to mature non-nesting males, and to identify potential life-history traits related to egg...

  16. Call recognition and individual identification of fish vocalizations based on automatic speech recognition: An example with the Lusitanian toadfish

    Vieira, Manuel; Fonseca, Paulo Jorge; Amorim, Maria Clara Pessoa; Teixeira, Carlos J. C.
    The study of acoustic communication in animals often requires not only the recognition of species specific acoustic signals but also the identification of individual subjects, all in a complex acoustic background. Moreover, when very long recordings are to be analyzed, automatic recognition and identification processes are invaluable tools to extract the relevant biological information. A pattern recognition methodology based on hidden Markov models is presented inspired by successful results obtained in the most widely known and complex acoustical communication signal: human speech. This methodology was applied here for the first time to the detection and recognition of fish acoustic signals,...

  17. Niche segregation between immature and adult seabirds: Does progressive maturation play a role?

    Campioni, Letizia; Granadeiro, José Pedro; Catry, Paulo
    In long-lived species with slow maturation, prebreeders often represent a large percentage of the individuals alive at any moment, but their ecology is still understudied. Recent studies have found prebreeding seabirds to differ in their isotopic (and trophic) niche from adult breeders attending the same nesting colonies. These differences have been hypothesized to be linked to the less-developed foraging performance of younger and less-experienced immatures or perhaps to their inferior competitive abilities. Such differences from adults would wane as individuals mature (“the progressive ontogenetic shift hypothesis”) and could underpin the prolonged breeding deferral until adulthood displayed by those species. This study documents a marked difference...

  18. Asexual origin of brooding in the sea anemones Actinia equina and A. schmidti: Molecular evidence from the portuguese shore

    Pereira, Ana Martins; Cadeireiro, Emília Margarida; Robalo, Joana Isabel
    Reproduction by sexual or asexual viviparity is a common phenomenon in some anemone species. In this short communication, the origin of the brooded young of Actinia equina and A. schmidti from the Portuguese shore was investigated. DNA was extracted from 56 brooding adult Actinia sp. and the nuclear gene that codes for the 28S ribosomal subunit was sequenced. Species identity was then assessed using GenBank. In total, 50 individuals were A. schmidti, five were A. equina and one had a hybrid origin. Three adult anemones (the hybrid, one A. equina and one A. schmidti) possessed two different 28S sequences and so their offspring was selected for further analysis using the...

  20. Home sweet home: evidence for nest-fidelity in the rocky intertidal fish, the shanny Lipophrys pholis

    Martins, Joana; Almada, Frederico; Gonçalves, Ana Sofia Ribeiro; Coelho, Pedro Duarte; Jorge, Paulo
    The ability to be faithful to a particular area or site was analysed in the shanny Lipophrys pholis. Using passive integrated transponders, adults from a population of L. pholis at Cabo Raso, Portugal, were followed over a period of 3 years. The findings showed that site fidelity is a consistent behaviour during the breeding season with specific breeding males being found only in particular sectors within the area, and in specific nests throughout the years. The fact that, in general, L. pholis individuals were absent from the study area during the non-breeding season and breeding males were recorded returning to the...
