  2. Comment on “Marine plastic debris emits a keystone infochemical for olfactory foraging seabirds” by Savoca et al.

    Dell’Ariccia, Gaia; Phillips, Richard A.; Franeker, Jan A. van; Gaidet, Nicolas; Catry, Paulo; Granadeiro, José Pedro; Ryan, Peter G.; Bonadonna, Francesco
    In their recent paper, Savoca and collaborators (2016) showed that plastic debris in the ocean may acquire a dimethyl sulfide (DMS) signature from biofouling developing on their surface. According to them, DMS emission may represent an olfactory trap for foraging seabirds, which explains patterns of plastic ingestion among procellariiform seabirds. This hypothesis is appealing, but some of the data that Savoca et al. used to support their claim are questionable, resulting in a misclassification of species, as well as other decisions regarding the variables to include in their models. Furthermore, with their focus on a single lifestyle trait (nesting habit) of dubious relevance for explaining plastic...

  3. Assessing acoustic communication active space in the Lusitanian toadfish

    Alves, Daniel; Amorim, Maria Clara Pessoa; Fonseca, Paulo Jorge
    The active space of a signal is an important concept in acoustic communication as it has implications for the function and evolution of acoustic signals. However, it remains mostly unknown for fish as it has been measured in only a restricted number of species. We combined physiological and sound propagation approaches to estimate the communication range of the Lusitanian toadfish’s (Halobatrachus didactylus) advertisement sound, the boatwhistle (BW). We recorded BWs at different distances from vocalizing fish in a natural nesting site at ca. 2–3 m depth. We measured the representation of these increasingly attenuated BWs in the auditory pathway through the auditory evoked potential (AEP) technique. These measurements point to a...

  4. Albatrosses prospect before choosing a home: Intrinsic and extrinsic sources of variability in visit rates

    Campioni, Letizia; Granadeiro, José Pedro; Catry, Paulo
    In long-lived species with delayed maturity, prebreeders are expected to gather information by visiting and sampling the quality of potential nesting areas (prospecting), before they choose where to breed. In most seabirds, this process is important because, once recruited, individuals generally remain sitefaithful throughout their long reproductive life. As many seabirds are believed to display low levels of natal dispersal, it is possible that natal philopatry is an obligate strategy for most individuals, with prospecting being a negligible activity during the prebreeding stage. Using ringing information and GPS technology, we tracked breeding adults and prebreeder black-browed albatrosses, Thalassarche melanophris, from a colony of the Falkland Islands, during...

  5. Ontogenetic development of the inner ear saccule and utricle in the Lusitanian toadfish: Potential implications for auditory sensitivity

    Chaves, Patrícia Alexandra Pereira; Valdoria, Ciara M.C.; Amorim, Maria Clara Pessoa; Vasconcelos, Raquel Ornelas
    Studies addressing structure-function relationships of the fish auditory system during development are sparse compared to other taxa. The Batrachoididae has become an important group to investigate mechanisms of auditory plasticity and evolution of auditory-vocal systems. A recent study reported ontogenetic improvements in the inner ear saccule sensitivity of the Lusitanian toadfish, Halobatrachus didactylus, but whether this results from changes in the sensory morphology remains unknown. We investigated how the macula and organization of auditory receptors in the saccule and utricle change during growth in this species. Inner ear sensory epithelia were removed from the end organs of previously PFA-fixed specimens,...

  6. Status of birds of prey in Guinea-Bissau: First assessment based on road surveys

    Henriques, Mohamed; Lecoq, Miguel; Monteiro, Hamilton; Regalla, Aissa Said; Granadeiro, José Pedro; Catry, Paulo
    Several studies have reported marked declines in populations of birds of prey across the African continent, including West Africa. However, there are still regions of which virtually nothing is known, as is the case for Guinea-Bissau. Because birds of prey play important roles in ecosystems and several species are threatened, it is important to establish baseline knowledge on their status. This is the first study in the country focusing exclusively on birds of prey. We conducted 1 711 km of roadside transects from mid-February to the end of May 2016, covering most of Guinea-Bissau. In total 4 989 birds of 33 species were counted, of...

  7. Ecology and behaviour of Palm-nut Vultures Gypohierax angolensis in the Bijagós Archipelago, Guinea-Bissau

    Carneiro, Camilo André Ferreira Carneiro; Henriques, Mohamed; Barbosa, Castro; Tchantchalam, Quintino; Regalla, Aissa Said; Patrício, Ana R.; Catry, Paulo
    Populations of many vulture species have undergone substantial declines. In Africa, 82% are threatened and although research on vultures has increased, the biology and ecology of several species is still poorly known. The Palm-nut Vulture Gypohierax angolensis has peculiar ecological characteristics, feeding on palm fruits, associated with the aquatic environment and taking a wide variety of prey. It has been over 40 years since the last thorough study on the ecology of the species was undertaken. This study investigated several ecological and behavioural aspects of Palm-nut Vultures, using a combination of direct observations, stable isotope analysis and Bayesian mixing models. The population of this species within...

  8. Computer-manipulated stimuli as a research tool in Mozambique tilapia Oreochromis mossambicus

    Wackermannova, Marie Anna; Horky, Pavel; Amorim, Maria Clara Pessoa; Fonseca, Paulo Jorge
    Multimodal communication is essential in social interactions in cichlid fish, including conspecifics’ recognition, agonistic interactions and courtship behaviour. Computer-manipulated image stimuli and sound playback offer powerful tools to assess the relative relevance of visual and acoustic stimuli in fish behavioural studies, but these techniques require validation for each taxon. The aim of the present study was to investigate whether Mozambique tilapia Oreochromis mossambicus responds to computermanipulated visual stimuli and acoustic playback. Six experiments were conducted: computer animation playback, video playback, interaction with a mirror, presentation of a live male in a jar alone and combined with courting sound playback or with white noise playback. Individual agonistic interactions (lateral displays, up and down swimming, butting)...

  9. The european anchovy, a genetically highly diverse species displays null within-sample haplotype diversity on a single study?

    Castilho, Rita; Silva, Gonçalo
    The European anchovy has been the focus of numerous population genetic studies, most of which exposing high levels of haplotype diversity. However, Keskin and Atar (2012) revealed rather singular results of null haplotype diversities. We therefore call for caution when considering these findings.

  11. Two new species of Tardigrada (Eutardigrada: Ramazzottiidae, Macrobiotidae) from the supralittoral zone of the Atlantic Iberian Peninsula rocky shores

    Fontoura, Paulo; Rubal, Marcos; Veiga, Puri
    Two new species of Eutardigrada were found in supralittoral lichens, growing on rocky shores at two localities of the Western Atlantic coast of the Iberian Peninsula. Ramazzottius littoreus sp. nov., found in San Cibrao (North of Spain), has the dorsal cuticle sculptured with small tubercles and claws with accessory points similar to R. oberhaeuseri. It can be distinguished from all the other known Ramazzottius species with the same type of cuticular sculpture by the dotted egg shell and the peculiar reticulation visible at the bulbous base of egg processes. Macrobiotus halophilus sp. nov., found in Cascais (Centre of Portugal), belongs to the Macrobiotus hufelandi group....

  13. Habitat associations and behavioural patterns of Symphodus spp. (Pisces: Labridae)

    Rodrigues, Diana Duarte; Costa, Bárbara Horta e; Cabral, Henrique; Gonçalves, Emanuel João
    The complexity and diversity of physical and biotic habitats are important features influencing the composition of shallow water reef fish assemblages, especially in temperate regions where abundant and diverse algal cover may have an important habitat-forming role. Coastal fish have adapted to these diverse habitats and to the temporal and spatial variations of algal assemblages in different ways. Wrasses are an important group of coastal rocky reef fish which present particular associations to algae in temperate systems. In this study, habitat associations were analysed in three species of wrasses: Symphodus bailloni, Symphodus melops and Symphodus roissali, and their behaviour was recorded. Eight main behavioural categories (comprising a total of 42 different behaviours) were...

  15. 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...

  16. 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...

  17. 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...

  18. 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...

  20. 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....
