Trait-based vulnerability and tolerance thresholds of tropical mollusks in ligh...
Suárez-Mozo, Nancy Yolimar; Angeles-Gonzalez, Luis Enrique; Moulatlet, Gabriel M.; Hernández-Ceballos, Ana Dianel; Díaz, Fernando; Vinagre, CatarinaExtreme climate conditions increasingly threaten worldwide coastal biodiversity. We applied a trait-based approach to quantify the tolerance thresholds of 13 mollusk species from five tropical coastal habitats, using controlled experiments that simulate extreme temperature, salinity, submersion, and desiccation stress. Survival was analyzed in relation to functional traits, including isolation from ambient cond...
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...
Network analysis reveals humans as top predators and the key role of cuttlefish...
Vinagre, Catarina; Almeida, Luis Pedro; Ronquillo, Pilar; Alegria Mendonça, Vanessa Sofia; Frade, Duarte; Gonçalves, Emanuel J.; Erzini, KarimThe marine protected area (MPA) of the Arrábida Natural Park is a mid-latitude hotspot for biodiversity. To understand its trophic structure, a highly defined food web network was assembled for this ecosystem, consisting of 884 taxa. Network analysis showed that humans are the top predators, as well as various seabirds, dolphins and sharks. This web is dominated by intermediate species, and its general organiza...
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...
