Multiple killer whales of the Iberian subpopulation interact with boats by establishing physical contact through bumping and pushing. First reported broadly in 2020, this disruptive behavior has since caused considerable damage to hundreds of vessels. Even though there are various hypotheses for what drives these interactions, the cause and purpose of this behavior are not yet understood. Here, we report on seven events betwee...
Habitat Preference of Risso's Dolphins ( Grampus griseus ) off the South Coast of PortugalNARA Subscribed
Information on the occurrence and ecology of Risso's dolphins off the southern coast of Portugal is limited and poorly understood. This study investigated the occurrence of this species in the Algarve via presence‐absence models. In total 63 Risso's dolphin sightings were recorded with an average group size of 10 animals and a presence of immature animals in most groups (73.02%). Generalized Additive Models were fitted to test...
Geography and ecology shape the phylogenetic composition of Amazonian tree communitiesNARA Subscribed
Aim Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types. Location Amazonia. Taxon A...
Geographic patterns of tree dispersal modes in Amazonia and their ecological correlatesNARA Subscribed
Aim To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser‐availability hypothesis) and/or the availability of resources for constructing zoocho...
MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugalNARA Subscribed
Mammals are threatened worldwide, with ~26% of all species being included in the IUCN threatened categories. This overall pattern is primarily associated with habitat loss or degradation, and human persecution for terrestrial mammals, and pollution, open net fishing, climate change, and prey depletion for marine mammals. Mammals play a key role in maintaining ecosystems functionality and resilience, and therefore information o...
Fresh and saline submarine groundwater discharge in a large coastal inlet affected by seasonal upwellingNARA Subscribed
Submarine groundwater discharge is recognized as a major source of chemicals to the global ocean, exerting large control over coastal water composition. Radon and 226 Ra are used to evaluate, for the first time, the occurrence and magnitude of submarine groundwater discharge in the Ría de Vigo, a large, highly productive embayment affected by seasonal, wind‐driven upwelling. The system is naturally enriched in 222 Rn due to th...
ATLANTIC BIRD TRAITS : a data set of bird morphological traits from the Atlantic forests of South AmericaNARA Subscribed
Scientists have long been trying to understand why the Neotropical region holds the highest diversity of birds on Earth. Recently, there has been increased interest in morphological variation between and within species, and in how climate, topography, and anthropogenic pressures may explain and affect phenotypic variation. Because morphological data are not always available for many species at the local or regional scale, we a...
The ontogenesis of the saccus vasculosus ( SV ) of turbot Scophthalmus maximus is described using histological and immunohistochemical methods to assess the general morphology, as well as the distribution of proliferative cells and several calcium‐binding proteins ( CaBP ). The results reveal that the SV begins to differentiate on hatching, when immature coronet cells are morphologically distinguishable. Further morphogenesis...
