  3. Behavioural lateralization and shoaling cohesion of fish larvae altered under ocean acidification

    Lopes, Ana Filipa; Morais, Pedro; Pimentel, Marta S,; Rosa, Rui; Munday, Philip L.; Gonçalves, Emanuel J.; Faria, Ana Margarida
    Recent studies have shown that the behaviour and development of coral reef fish larvae is hampered by projected future CO2 levels. However, it is uncertain to what extent this effect also occurs in temperate species. The effects that elevated pCO2 (~2000 μatm) levels, which are expected to occur in coastal upwelling regions in the future, have on shoaling behaviour and lateralization (turning preference) of fish, were tested in temperate sand smelt Atherina presbyter larvae. The hypothesis that behavioural changes are caused by interference of high CO2 with GABA-A receptor function was tested by treating larvae with a receptor antagonist (gabazine). Routine swimming speed did not differ between control and high pCO2, but exposure...

  4. A new Batillipes (Tardigrada, Heterotardigrada, Batillipedidae) from North Portugal (Atlantic Ocean)

    Rubal, Marcos; Veiga, Puri; Fontoura, Paulo; Sousa-Pinto, Isabel
    The knowledge of marine tardigrades in the Iberian Peninsula is very scarce in comparison with those from limnoterrestrial environments. As part of an effort to improve the knowledge of marine tardigrades in the Iberian Peninsula, a new species of marine tardigrade, Batillipes minius sp. nov., is described from shallow subtidal coarse sand collected at Moledo, Northern Portugal, close to the mouth of the Minho river. The new species differs from all other Batillipes species by its combination of toe pattern, dorsal and ventral lateral projections, caudal apparatus, cuticle segmentation and the presence of a dorsal indentation in its head. This new species was found in well-oxygenated, shallow subtidal, mediumcoarse sand with low...

  5. Reproductive trade-offs in a temperate reef fish under high pCO2 levels

    Faria, Ana Margarida; Lopes, Ana F.; Silva, Cátia Sofia E.; Novais, S.C.; Lemos, M.F.L.; Gonçalves, Emanuel João
    Fishes are currently facing novel types of anthropogenic stressors that have never experienced in their evolutionary history, such as ocean acidification. Under these stressful conditions, energetically costly processes, such as reproduction, may be sacrificed for increased chances of survival. This trade-off does not only affect the organism itself but may result in reduced offspring fitness. In the present study, the effects of exposure to high pCO2 levels were tested on the reproductive performance of a temperate species, the two-spotted goby, Gobiusculus flavescens. Breeding pairs were kept under control (∼600 μatm, pH∼ 8.05) and high pCO2 levels (∼2300 μatm, pH∼ 7.60) conditions for a 4-month period. Additionally,...

  6. Flexible migratory choices of Cory’s shearwaters are not driven by shifts in prevailing air currents

    Dell’Ariccia, Gaia; Benhamou, Simon; Dias, Maria P.; Granadeiro, José Pedro; Sudre, Joel; Catry, Paulo; Bonadonna, Francesco
    Wind conditions strongly affect migratory costs and shape flyways and detours for many birds, especially soaring birds. However, whether winds also influence individual variability in migratory choices is an unexplored question. Cory's shearwaters (Calonectris borealis) exhibit migratory flexibility, changing non-breeding destination across the Atlantic Ocean within and between years. Here, we investigated how wind dynamics affect the spatiotemporal migratory behaviour and whether they influence individual choices of non-breeding destination. We analysed 168 GLS tracks of migratory Cory's shearwaters over five years in relation to concurrent wind data. We found no evidence for an association of the use of specific paths...

  8. Not in wilderness: African vulture strongholds remain in areas with high human density

    Henriques, Mohamed; Granadeiro, José Pedro; Monteiro, Hamilton; Nuno, Ana; Lecoq, Miguel; Cardoso, Paulo Eduardo; Regalla, Aissa Said; Catry, Paulo
    Vultures constitute an important functional group in many ecosystems, providing crucial ecosystem services both in natural and humanized environments. These scavengers are facing massive declines worldwide, but in several African countries virtually nothing is known on populations' status and threats, hampering the development of adequate conservation strategies. In Guinea-Bissau, globally important populations of Hooded Necrosyrtes monachus and African white-backed vultures Gyps africanus were recently reported. Using the country as a study area, we aim to characterize human-vulture interactions in West Africa applying a multidisciplinary approach. We assessed the status and distribution of vulture populations using data from 1711 km of...

  9. Daily variation in behavioural lateralization is linked to predation stress in a coral reef fish

    Ferrari, Maud C.O.; McCormick, Mark Ian; Mitchell, Matthew David .; Allan, Bridie J.M.; Gonçalves, Emanuel João; Chivers, Douglas P.
    Behavioural lateralization, the preferential use of one side of the body or one of the limbs, is a trait common in vertebrates, and is often expressed as a turning bias in fishes. Recent studies have demonstrated considerable plasticity in lateralization, inferring the role of predation pressure as a key driver of this plasticity over short periods (i.e. days). Such plasticity may be expected if predator pressure is highly variable through space and time and can provide prey with a distinct advantage.We know that increased turning bias is linked with better escape performance, but we do not know the extent to which prey can adjust this trait...

  11. Genetic population structure of black-browed and Campbell albatrosses, and implications for assigning provenance of birds killed in fisheries

    Burg, Theresa M.; Catry, Paulo; Ryan, Peter G.; Phillips, Richard A.
    1. Previous genetic studies found evidence of at least three distinct groups of black‐browed Thalassarche melanophris and Campbell Thalassarche impavida albatrosses in the Southern Ocean. Almost 350 individuals including samples from additional breeding sites on the Falkland Islands and South Georgia Island were screened using mitochondrial DNA. 2. The new sequence data using lineage specific PCR primers provided further support for the taxonomic split of T. melanophris and T. impavida and separate management of the two distinct T. melanophris groups. 3. In total, 207 black‐browed albatrosses killed in longline fisheries were screened. Approximately 93% of the bycaught birds from the Falkland Islands belonged to the Falkland mtDNA group and...

  12. 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...

  13. 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...

  14. 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...

  15. 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...

  16. 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...

  17. 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...

  20. 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,...
