Effects of biological and environmental factors on the variability of Paralonch...
Costa, Eudriano; Teixeira, Gustavo M.; Freire, Fúlvio A. M.; Dias, June F.; Fransozo, AdilsonThe hypothesis of this study was based on the premise that complex interactions between biological and environmental factors may explain variability in fish population dynamics. To test this, Paralonchurus brasiliensis (Sciaenidae), a keystone species associated with coastal waters, was used as a model fish species. Generalized Additive Models for Location, Scale and Shape were performed to evaluate relationshi...
The ocean in a box: water density gradients and discontinuities in water masses...
Baptista, Vânia; Morais, Pedro; Costa, Eudriano; Cruz, Joana; Teodosio, MariaDiscontinuities and gradients in water density are predominant features that may guide coastal fish larvae towards their estuarine nursery grounds when within the influence of an estuarine plume (Lindeman et al. 2000; Atema et al. 2002; Kingsford et al. 2002; Hale et al. 2008; James et al. 2008). When larvae are away from the estuarine plume zone, larvae may follow patchy estuarine cues that may lead them towar...
Climate change vulnerability assessment of the main marine commercial fish and ...
Bueno-Pardo, Juan; Nobre, Daniela; Monteiro, J. N.; Sousa, Pedro M.; Costa, Eudriano; Baptista, Vânia; Ovelheiro, Andreia; Vieira, Vasco; Chicharo, LuisThis is the first attempt to apply an expert-based ecological vulnerability assessment of the effects of climate change on the main marine resources of Portugal. The vulnerability, exposure, sensitivity, adaptive capacity, and expected directional effects of 74 species of fish and invertebrates of commercial interest is estimated based on criteria related to their life-history and level of conservation or explo...
Ingestion of macroplastics by common dolphinfish (Coryphaena hippurus) in the A...
Costa, Eudriano; Dias, June Ferraz; Madureira, Lauro Antônio Saint PastousThe anthropogenic impact of pollution by plastic debris has threatened marine life inhabiting benthic and pelagic habitats from the poles to the equa tor (e.g., Ryan and Moloney, 1993; Derraik, 2002; Thompson et al., 2004). The ingestion of plastics by marine organisms is an increasing global trend due to the increase of these polymers in the oceans (e.g., Lusher et al., 2013; Besseling et al., 2015; Lusher et ...
Does consistent individual variability in pelagic fish larval behaviour affect ...
Baptista, Vânia; Costa, Eudriano; Carere, Claudio; Morais, Pedro; Cruz, Joana; Cerveira, Inês; Castanho, Sara; Ribeiro, Laura; Pousao-Ferreira, PedroIndividual animals across all taxa differ consistently in behaviour, i.e. they show personality traits. This inter-individual variability has significant ecological and evolutionary consequences, since it affects a range of population-level processes. Here, we focus on the selection and recruitment of nursery habitats in temperate fish larvae. The "Sense Acuity and Behavioural Hypothesis" has proposed that fish...
