Abstract The conservation of migratory marine species, including pelagic seabirds, is challenging because their movements span vast distances frequently beyond national jurisdictions. Here, we aim to identify important aggregations seabirds in the North Atlantic inform ongoing regional efforts. Using tracking, phenology, and population data, mapped abundance diversity 21 seabird species. This revealed a major hotspot associated with discrete area subpolar frontal zone, used annually by 2.9–5...
Methylmercury poisoning may cause constriction of visual fields and deafness, especially if exposure occurs prenatally. However, the risks associated with from contaminated seafood is unclear. We examined 149 children attending first grade in a Madeiran fishing community. As maternal dietary habits were relatively unchanged, current hair concentrations used as indicator child's prenatal to methylmercury (geometric average, 9.64 μg/g [48.2 nmol/g]). After adjustment for age sex, mean (±SD)...
Abstract Aim Anthropogenic activities alter and constrain the structure of marine ecosystems with implications for wide‐ranging vertebrates. In spite environmental importance vast oceanic ecosystems, most conservation efforts mainly focus on neritic areas. To identify relevant areas conservation, we assessed year‐round spatial distribution spatio‐temporal overlap eight truly seabird species gadfly petrels ( Pterodroma spp.) inhabiting Atlantic Ocean. Location Methods Using tracking data...
Abstract Aim Our current understanding of migratory strategies and the reasons for their high variability along phylogenetic tree remains relatively poor. Most hypotheses relating to migration have been formulated terrestrial taxa; classically, oceanic migrations were considered as merely dispersive because scarcity observations in open ocean. We describe first time, strategy a small seabird, Bulwer's petrel ( Bulweria bulwerii ), provide new insights into ecology evolution long‐distance...
The conservation status and taxonomy of the three gadfly petrels that breed in Macaronesia is still discussed partly due to scarce information on their spatial ecology. Using geolocator capture-mark-recapture data, we examined phenology, natal philopatry breeding-site fidelity, year-round distribution, habitat usage at-sea activity closely-related Macaronesia: Zino's petrel Pterodroma madeira, Desertas P. deserta Cape Verde feae. All feae remained around breeding area during non-breeding...
Abstract Macaronesia (north‐east A tlantic archipelagos) has been host to complex patterns of colonization and differentiation in many groups organisms including seabirds such as gadfly petrels (genus P terodroma ). Considering the subspecies widely distributed soft‐plumaged petrel for years, taxonomic status three taxa breeding M acaronesia is not yet settled, some authors advocating presence three, two or one species. These birds have already subject genetic studies with only mt DNA gene...
In Cory's Shearwater Calonectris diomedea on Selvagem Grande (30°09'N, 15°52'W), fledging weight influences the survival of chicks during first weeks their life at sea, larger fledglings having a higher probability survival. This is true for males as well females. There no apparent effect date fledging.
The taxonomic status of petrels from the North East Atlantic has long been a matter debate. Breeding colonies occurring on islands Madeira, Bugio and Cape Verde were originally thought to be outlying populations polytypic species Pterodroma mollis . Subsequent treatments have varied considerably in their classification birds these islands. petrel Madeira represent some Europe's rarest breeding exact designation, hence relation conservation mandates, is question considerable importance. In...

Abstract Seabirds inhabiting vast water masses provide numerous examples where opposing phenomena, such as natal and breeding philopatry vs. vagility have dug cryptic taxonomic boundaries among closely related taxa. The taxonomy of little shearwaters the North Atlantic Ocean (Little–Audubon’s shearwater complex, Puffinus assimilis–lherminieri) still remains unclear, complementary information on non-breeding distributions at-sea behaviour becomes essential to unravel divergent local...
The breeding success of Cory's shearwaters Calonectris diomedea borealis at its important Atlantic colony on Selvagem Grande has been monitored periodically two study plots since 1982. A successful eradication programme was implemented to remove alien invasive mammals, rabbits Oryctolagus cuniculus and house mice Mus musculus, from the island during 2002. availability long-term data for provided a unique opportunity effects removal seabird breeding. Annual observation approximately 400 nests...

Abstract The largest colony of Cory's shearwater Calonectris borealis nests on the island Selvagem Grande in north-eastern Atlantic. In 2002, a programme eradication was conducted to remove two alien invasive mammals, house mouse Mus musculus and European rabbit Oryctolagus cuniculus . Preliminary studies recorded beneficial effects eradications for variety plant animal species, including shearwater. We fledging rates shearwaters 1982–2001, prior eradication, 2002–2020, after from quadrats,...

Plant specimens obtained by the authors from several expeditions to Selvagens Islands (2004-2021), complemented study of herbarium specimens, led identification new species records for archipelago, namely taxa currently considered as Canary endemics Trisetaria lapalmae and Polycarpaea divaricata. Other include Convolvulus siculus subsp. elongatus grasses Bromus rigidus Phalaris minor. Notes on Misopates salvagense, Asplenium marinum, Spergularia diandra Rostraria pumila are also included....
