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

    Solomon, Farahnaz N.; Rodrigues, Diana Duarte; 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...

  2. Involvement of the avian dorsal thalamic nuclei in homing pigeon navigation

    Jorge, Paulo E.; Pinto, Belmiro V.; Bingman, Verner P.; Phillips, John B.
    The navigational ability of birds has been a focus of popular and scientific interest for centuries, but relatively little is known about the neuronal networks that support avian navigation. In the brain, regions like the piriform cortex, olfactory bulbs, hippocampal formation, vestibular nuclei, and the wulst, are among the brain regions often discussed as involved in avian navigation. However, despite large literature showing a prominent role of some anterior and dorsal thalamic nuclei in mammalian spatial navigation, little is known about the role of the thalamus in avian navigation. Here, we analyzed a possible role of the dorsal anterior thalamic...

  3. Noise can affect acoustic communication and subsequent spawning success in fish

    Jong, Karen de; Amorim, Maria Clara Pessoa; Fonseca, Paulo João; Fox, Clive J.; Heubel, Katja U.
    There are substantial concerns that increasing levels of anthropogenic noise in the oceans may impact aquatic animals. Noise can affect animals physically, physiologically and behaviourally, but one of the most obvious effects is interference with acoustic communication. Acoustic communication often plays a crucial role in reproductive interactions and over 800 species of fish have been found to communicate acoustically. There is very little data on whether noise affects reproduction in aquatic animals, and none in relation to acoustic communication. In this study we tested the effect of continuous noise on courtship behaviour in two closely-related marine fishes: the two-spotted goby (Gobiusculus flavescens) and the painted goby (Pomatoschistus...

  4. Nest-site characteristics and aspects of the breeding biology of the endangered Timneh Parrot Psittacus timneh in Guinea-Bissau

    Lopes, Daniel C; Martin, Rowan O; Henriques, Mohamed; Monteiro, Hamilton; Regalla, Aissa Said; Tchantchalam, Quintino; Indjai, Bucar; Cardoso, Seco; Manuel, Celestino; Cunha, Manjaco; Cunha, Domingos; Catry, Paulo
    Timneh Parrots Psittacus timneh are endemic to the moist forests of West Africa. Concerns over rapid declines in populations due to overharvesting for the pet trade and forest loss prompted the species’ categorisation as Endangered on the IUCN Red List of Threatened Species in 2016. Despite these threats, few data exist on their biology in the wild, impeding the development of effective conservation initiatives to protect populations. One of the few recorded breeding sites for this species occurs in the Bijagós Archipelago in Guinea-Bissau, where chicks have been historically harvested from nests and forest clearance for agriculture is common. We investigated the breeding ecology of Timneh...

  5. Mitochondrial and nuclear intraspecific variation in the rusty blenny (Parablennius sanguinolentus, Blenniidae)

    Pappalardo, Anna Maria; Francisco, Sara M.; Fruciano, Carmelo; Lima, Cristina Silva.; Pulvirenti, Valentina; Tigano, C.; Robalo, Joana Isabel; Ferrito, V.
    The genetic structure of Parablennius sanguinolentus from the northeastern Atlantic and Mediterranean was assessed using sequences from the mitochondrial control region (CR) and the first intron of the nuclear S7 ribosomal protein gene (S7). Our data show high genetic diversity for the central Mediterranean populations, contrasting with very low diversity in the Atlantic populations and in the westernmost Mediterranean population of Cabo de Gata. Both CR mismatch analysis and neutrality tests provide evidence of demographic and spatial expansion for the Atlantic and central Mediterranean populations. The significant correlation between genetic and geographic distances supported isolation- by-distance for the S7, but not for the CR, suggesting a complex scenario for the history of the rusty blenny in...

  6. Contrasts in the marine ecosystem of two Macaronesian islands: A comparison between the remote Selvagens Reserve and Madeira Island

    Friedlander, Alan M.; Ballesteros, Enric; Clemente, Sabrina; Gonçalves, Emanuel J.; Estep, Andrew; Rose, Paul; Sala, Enric
    The islands of Madeira and Selvagens are less than 300 km apart but offer a clear contrast between a densely populated and highly developed island (Madeira), and a largely uninhabited and remote archipelago (Selvagens) within Macaronesia in the eastern Atlantic. The Madeira Archipelago has ~260,000 inhabitants and receives over six million visitor days annually. The Selvagens Islands Reserve is one of the oldest nature reserves in Portugal and comprises two islands and several islets, including the surrounding shelf to a depth of 200 m. Only reserve rangers and a small unit of the maritime police inhabit these islands. The benthic...

  9. Absence of haemosporidian parasite infections in the long-lived Cory’s shearwater: evidence from molecular analyses and review of the literature

    Campioni, Letizia; Martínez-de la Puente, Josué; Figuerola, Jordi; Granadeiro, José Pedro; Silva, Mónica C.; Catry, Paulo
    The apparent scarcity or absence of blood parasites in some avian groups, such as seabirds, has been related to intrinsic and extrinsic factors including host immunological capacity, host-parasite assemblage, and ecological parameters, but also to reduced sensitivity of some methods to detect low parasite prevalence/intensities of infection. Here, we examined the haemosporidian parasite prevalence in a breeding population of Cory's shearwater Calonectris diomedea borealis, a long-distance migrant seabird, nesting in the Macaronesian region, in the Eastern Atlantic. Previous studies on Calonectris diomedea complex were based on small sample sizes providing weak evidence for a lack of infections by haemoparasites. Here,...

  11. Major, minor, trace and rare earth elements in sediments of the Bijagós archipelago, Guinea-Bissau

    Carvalho, Lina; Figueira, Paula; Monteiro, Rui J. R.; Reis, Ana Teresa; Almeida, Joana C.; Catry, Teresa; Lourenço, Pedro Miguel; Catry, Paulo; Barbosa, Castro; Castro, Inês; Pereira, Eduarda; Pereira, Eduarda; Granadeiro, José Pedro; Vale, Carlos
    Sixty sediment samples from four sites in the Bijagós archipelago were characterized for fine fraction, loss on ignition, major, minor and trace elemental composition (Al, Fe, Ca, Mg, Ti, P, Zr, Mn, Cr, Sr, Ba, B, V, Li, Zn, Ni, Pb, As, Co, U, Cu, Cs and Cd), and the elements of the La–Lu series. Element concentrations were largely explained by the Al content and the proportion of fine fraction content, with the exception of Ca and Sr. Sediments showed enhanced Ti, U, Cr, As and Cd concentrations with respect to estimated upper crust values, most likely mirroring a regional signature. Rare earth elements were...

  12. Cryptic effects of biological invasions: Reduction of the aggressive behaviour of a native fish under the influence of an "invasive" biomolecule

    Magliozzi, Laura; Almada, Frederico; Robalo, Joana Isabel; Mollo, Ernesto; Polese, Gianluca; Gonçalves, Emanuel João; Felline, Serena; Terlizzi, Antonio; D'Aniello, Biagio
    The invasive green alga Caulerpa cylindracea has become an important component of the diet of the Mediterranean white seabream Diplodus sargus. As a consequence of this ªexotic dietº, the algal bisindolic alkaloid caulerpin accumulates in the fish tissues. Although the compound shows structural similarity to endogenous indolamines that modulate animal behaviour, the potential impact of caulerpin on fish behaviour still remains unexplored. In this report, behavioural experiments both on groups and on single fish responding towards a mirror were performed under different doses of dietary caulerpin. Differences between treated and control groups for each behaviour and for the overall aggressive pattern during the different experimental phases showed that...

  14. Evidence for contrasting accumulation pattern of cadmium in relation to other elements in Senilia senilis and Tagelus adansoni from the Bijagós archipelago, Guinea-Bissau

    Catry, Teresa; Figueira, Paula; Carvalho, Lina; Monteiro, Rui J. R.; Coelho, Pedro Duarte; Lourenço, Pedro Miguel; Catry, Paulo; Tchantchalam, Quintino; Catry, Inês; Botelho, Maria J.; Pereira, Eduarda; Granadeiro, José Pedro; Vale, Carlos
    Shellfish harvesting in intertidal areas is a widespread and economically important activity in many countries across West Africa. However, in some areas, there is virtually no information concerning the levels of contaminants (and other elements related to nutritional aspects) in the harvested species. We collected sediments and several individuals of the West African bloody cockle Senilia senilis and of the razor clam Tagelus adansoni during the dry season of 2015 nearby three islands in the Bijagós archipelago, Guinea-Bissau. Aluminium, Ca, Fe, Mg, As, Cd, Co, Cr, Cu, Mn, Ni, Pb and Zn were determined in sediments and whole soft tissues...

  20. 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...
