The Impact of Breeding Yellow-Legged Gulls on Vegetation Cover and Plant Compos...

Portela, Diogo; Pereira, Jorge M.; Cerveira, Lara R.; Paiva, V. H.; Ramos, Jaime A.

The establishment of large populations of yellow-legged gull Larus michahellis in coastal and urban areas can lead to strong changes in vegetation cover and composition through creating physical disturbance in the vegetation and impacting the soil quality through defecation. In this study, we evaluated the effects of breeding yellow-legged gull populations on tall and short vegetation cover and plant species co...


Quantifying annual spatial consistency in chick-rearing seabirds to inform impo...

Animal tracking has afforded insights into patterns of space use in numerous species and thereby informed areabased conservation planning. A crucial consideration when estimating spatial distributions from tracking data is whether the sample of tracked animals is representative of the wider population. However, it may also be important to track animals in multiple years to capture changes in distribution in res...


Global assessment of marine plastic exposure risk for oceanic birds

Clark, Bethany L.; Carneiro, Ana P. B.; Pearmain, Elizabeth J.; Rouyer, Marie-Morgane; Clay, Thomas A.; Cowger, Win; Phillips, Richard A; Manica, Andrea

Plastic pollution is distributed patchily around the world's oceans. Likewise, marine organisms that are vulnerable to plastic ingestion or entanglement have uneven distributions. Understanding where wildlife encounters plastic is crucial for targeting research and mitigation. Oceanic seabirds, particularly petrels, frequently ingest plastic, are highly threatened, and cover vast distances during foraging and m...


Dynamics and effects of plastic contaminants’ assimilation in gulls

Veríssimo, S. N.; Cunha, S. C.; Fernandes, J. O.; Casero, M.; Vieira, M. T.; Ramos, J. A.; Norte, A. C.; Paiva, V. H.

Background: Opportunistic animals such as gulls are often associated with anthropogenic activities [1,2], and therefore highly susceptible to plastic ingestion and stomach chemical leaching [3]. Yet, such chemical process is still poorly studied and there is almost no information regarding potential hazardous effects in animal physiological processes. Even though it was already reported that gulls accumulate Po...

Seabirds as bioindicators of anthropogenic and chemical pollution

Matos, D. M.; Ramos, J. A.; Brandão, L. C.; Bessa, F.; Silva, V.; Rodrigues, I.; Antunes, S.; dos Santos, I.; Coentro, J.; Cunha, S. C.

Background: Marine pollution, caused by anthropogenic debris, is a significant environmental issue that has detrimental effects on marine ecosystems ​[1]​. Finding suitable sentinel species of the human impacts on the oceans, is imperative. As top predators, seabirds are considered sentinels of the marine environment ​[2]​. Objective: To provide quantitative data about the distinctive prevalence of anthropogeni...

First representation of the trophic structure and functioning of the Portuguese...

Veiga-Malta, T.; Szalaj, D.; Angelico, M. M.; Azevedo, M.; Farias, I; Garrido, S.; Lourenco, S.; Marçalo, Ana; Marques, V; Moreno, A.; Oliveira, P. B.

In this study, we analysed the structure and functioning of the Portuguese continental shelf ecosystem and investigated the role of sardine Sardina pilchardus using the Ecopath massbalance approach. An Ecopath model was configured to represent the continental shelf waters in the period 2006-2009. The model showed that biomass was concentrated in low and intermediate trophic levels as in other upwelling areas. S...

Carrilho, Rui M. B.; Pereira, Mariette M.; Maria, Teresa M. R.; Eusébio, M. Ermelinda; Paiva, V. H.

In the title compound, C28H19F3O4S, a new 2'-benz-yloxy (R)-BINOL derivative containing a tri-fluoro-methane-sulfonate group in the 2-position, the planes of the two naphthyl ring systems (r.m.s. deviations = 0.012 and 0.019 Å) are at an angle of 73.36 (2)°, and the planes of the benzyl ring and the naphthyl ring system bound to the ether O atom are at an angle of 75.67 (4)°. In the crystal, mol-ecules are link...


Polar marine biology science in Portugal and Spain: Recent advances and future ...

Xavier, J.; Barbosa, Ana B.; Agustí, S.; Alonso-Sáez, L.; Alvito, P.; Ameneiro, J.; Ávila, C.; Baeta, A.; Canário, J.; Carmona, R.; Catry, P.; Ceia, F.

Polar marine ecosystems have global ecological and economic importance because of their unique biodiversity and their major role in climate processes and commercial fisheries, among others. Portugal and Spain have been highly active in a wide range of disciplines in marine biology of the Antarctic and the Arctic. The main aim of this paper is to provide a synopsis of some of the results and initiatives undertak...
