The Case of a Rudderfish Highlights the Role of Natural History Museums as Sentinels of Bio-invasions
2017
In September 2013 fishermen captured a rudderfish—Kyphosus vaigiensis—off Favignana Island, one of the islands of the Egadi Islands Marine Protected Area (MPA) in western Sicily (Mannino et al., 2015). This species is rarely sampled in the Mediterranean Sea.
Fishery-induced selection for slow somatic growth in European eel
2012
International audience; Both theoretical and experimental studies have shown that fishing mortality can induce adaptive responses in body growth rates of fishes in the opposite direction of natural selection. We compared body growth rates in European eel (Anguilla anguilla) from three Mediterranean stocks subject to different fishing pressure. Results are consistent with the hypotheses that i) fast-growing individuals are more likely to survive until sexual maturity than slow-growing ones under natural conditions (no fishing) and ii) fishing can select for slow-growing individuals by removing fast-growing ones. Although the possibility of human-induced evolution seems remote for a panmictic…
Northern refugia and recent expansion in the North Sea: The case of the wrasse Symphodus melops (Linnaeus, 1758)
2011
Pleistocene climate changes have imposed extreme conditions to intertidal rocky marine communities, forcing many species to significant range shifts in their geographical distributions. Phylogeographic analyses based on both mitochondrial and nuclear genetic markers provide a useful approach to unravel phylogeographic patterns and processes of species after this time period, to gain general knowledge of how climatic changes affect shifts in species distributions. We analyzed these patterns on the corkwing wrasse (Symphodus melops, Labridae), a rocky shore species inhabiting North Sea waters and temperate northeastern Atlantic Ocean from Norway to Morocco including the Azores, using a fragme…
Malebranche: el placer dinámico y ordenado
2021
La crítica señala a Pierre Nicole como el pensador que hizo la transición entre aquellos primeros moralistas de mediados del siglo xvii que condenaban el mundo terrenal, y adoptaban una actitud negativa del ser humano, y los moralistas de la primera mitad del siglo xviii, cuya visión moderna y mundana concebía al hombre bajo una perspectiva positiva. Este estudio pretende ubicar a Nicolas Malebranche como el otro pensador, quizá más en la sombra, quizá con un modo no tan explícito, que protagoniza dicha transición. Bajo el reinado de Luis XIV, el filósofo parisino, influenciado notablemente por San Agustín y Descartes, establece una psicología dinámica que le aleja del estático epicureísmo …
