Exposure of an intertidal fish to simulated heatwaves and suspended sediment – ...
Resende, Anna Carolina; Vinagre, Catarina; Rogers, AliceExtreme climatic events, such as marine heatwaves (MHW) and increased suspended sediment concentration (SSC), are increasing in frequency and intensity, resulting in sudden changes to coastal environments, especially intertidal zones. Intertidal animals experience conditions that substantially fluctuate over temporal and spatial scales and therefore require the ability to physiologically tolerate these fluctuat...
Physiological response of Palaemon elegans to multi-anthropogenic stressors: as...
Autiero, Alexandro; Martínez, Ico; Montesdeoca-Esponda, Sarah; Vinagre, Catarina; Gómez, May; Navarro, Alberto; Herrera, AliciaSunscreens UV filters have been identified as emerging pollutants, representing a toxic threat to aquatic environments. In addition to that, regions with intense sunscreen usage are usually exposed to marine heat waves. This study shows the combined effects of high-water temperatures associated with sunscreen exposure in Palaemon elegans (Rathke, 1836). A full factorial experiment tested two temperature conditi...
Shallow water fish display low phenotypic plasticity to ocean warming and extre...
Missionário, Madalena; Almeida, Célia; Fernandes, Joana Filipa; Vinagre, Catarina; Madeira, Carolina; Madeira, DianaShallow water environments have long been recognized by scientists as sentinels for climate change. By analysing the impacts of ocean warming and marine heatwaves (MHW) in species from these areas, we can estimate their plasticity and hence vulnerability to thermal challenges. Pomatoschistus microps is a benthic intertidal fish species inhabiting coastal lagoons where temperature fluctuations are common. Here, ...
Short food chains, highly diverse and complex food web networks in coastal lagoons
Vinagre, Catarina; López Gastón, CristinaShallow semi-enclosed coastal lagoons are recognized as important biodiversity hotspots and nursery areas for many organisms. However, the topology of the complex food web networks therein has never been studied. Highly defined food web networks were assembled for Ria de Aveiro, Ria de Alvor and Ria Formosa. Their structural network properties were analysed and compared to those of large open estuaries, small i...
Does heat tolerance actually predict animals' geographic thermal limits?
Camacho, Agustín; Rodrigues, Miguel Trefaut; Jayyusi, Refat; Harun, Mohamed; Geraci, Marco; Carretero, Miguel A.; Vinagre, Catarina; Tejedo, MiguelThe "climate extremes hypothesis" is a major assumption of geographic studies of heat tolerance and climatic vulnerability. However, this assumption remains vastly untested across taxa, and multiple factors may contribute to uncoupling heat tolerance estimates and geographic limits. Our dataset includes 1000 entries of heat tolerance data and maximum temperatures for each species' known geographic limits (herea...
Priority effects, environmental filtering and neutral coexistence explain large...
Barbosa, A. C.C.; Vinagre, Catarina; Kitahara, MV; Flores, A. A. V.Two sun coral species, Tubastraea tagusensis and T. coccinea, have successfully colonized reef habitats along the Southwest Atlantic. However, their invasive biology has been largely addressed without considering species-specific distribution patterns. Here, we assessed the distribution and abundance of Tubastraea spp. at vertical rocky reef sites within a number of islands along 120 km of coastline off the nor...
Thermal plasticity over a marine-estuarine ecocline can buffer a tropical fish ...
de Souza, Joice Silva; Vinagre, Catarina; dos Santos, Luciano NevesIntraspecific variation in thermal tolerance can favor species persistence in a warmer ocean, but is often over-looked in fine-scale studies. Nonetheless, local drivers (e.g. salinity) interact with temperature to shape species' thermal response. Here, we acclimated juveniles of Brazilian silversides Atherinella brasiliensis captured at the limits of a marine-estuarine ecocline under reciprocal-cross conditions...
Patterns of rock pool molluscs in differing shore exposures
Gonçalves, Inês; Vinagre, Catarina; Silva, AnaRock pools are understudied systems of extreme importance due to their proven vulnerability to climate change. Rock pool molluscs play essential ecological roles therein, directly by acting both as prey and predator and, indirectly by influencing the macroalgal canopy/vegetation topography via grazing. However, the environmental factors driving their rock pool occupation remain largely unknown. Our study is one...
Changing webs—Variation of complex networks over a tidal cycle in an intertidal...
Vinagre, Catarina; Mendonça, VanessaIncorporating temporal variation in models is one of the most important challenges in food web research. One of the environments where time causes profound changes is the intertidal zone, where the immersion-emersion cycle drastically changes the abiotic and biotic conditions. Intertidal rocky shores have been intensively studied, however the variation in the complex food web network that occurs during a tidal ...
Impacts of ocean warming and acidification on predator-prey interactions in the...
Guarizo, Matheus; Pardo, Juan C. F.; De Grande, Fernando Rafael; Vinagre, Catarina; Costa, Tânia MarciaThe effect of ocean warming and acidification on predator-prey interactions in the intertidal zone is a topic of growing concern for the scientific community. In this review, we aim to describe how scientists have explored the topic via research weaving, a combination of a systematic review, and a bibliometric approach. We assess articles published in the last decade exploring the impact of both stressors on pr...
