Ancient divergence in the trans-oceanic deep-sea shark Centroscymnus crepidater
Cunha, R. L.; Coscia, I.; Madeira, C.; Mariani, S.; Stefanni, S.; Castilho, RitaUnravelling the genetic structure and phylogeographic patterns of deep-sea sharks is particularly challenging given the inherent difficulty in obtaining samples. The deep-sea shark Centroscymnus crepidater is a medium-sized benthopelagic species that exhibits a circumglobal distribution occurring both in the Atlantic and Indo-Pacific Oceans. Contrary to the wealth of phylogeographic studies focused on coastal s...
Unexpected high genetic diversity at the extreme Northern geographic limit of T...
Almada, V. C.; Almada, F.; Francisco, S. M.; Castilho, Rita; Robalo, J. I.The longspined bullhead (Taurulus bubalis, Euphrasen 1786) belongs to the family Cottidae and is a rocky shore species that inhabits the intertidal zones of the Eastern Atlantic since Iceland, southward to Portugal and also the North Sea and Baltic, northward to the Gulf of Finland, with some occurrences in the northern Mediterranean coasts eastward to the Gulf of Genoa. We analysed the phylogeographic patterns...

Genetic evidence fails to discriminate between Macroramphosus gracilis Lowe 183...
Robalo, J. I.; Sousa-Santos, C.; Cabral, H.; Castilho, Rita; Almada, V. C.Fish belonging to the genus Macroramphosus are distributed throughout the Atlantic, Indian and PaciWc oceans. Some authors consider this genus monotypic, Macroramphosus scolopax being the only valid species. Other authors consider (based on several morphological and ecological characters) that another species (Macroramphosus gracilis) exists and occurs frequently in sympatry with the Wrst one. Intermediat...
Evaluating signatures of glacial refugia for North Atlantic benthic marine taxa
Maggs, C. A.; Castilho, Rita; Foltz, D.; Henzler, C.; Jolly, M. T.; Kelly, J.; Olsen, J. L.; Perez, K. E.; Stam, W. T.; Väinölä, R.; Viard, F.A goal of phylogeography is to relate patterns of genetic differentiation to potential historical geographic isolating events. Quaternary glaciations, particularly the one culminating in the Last Glacial Maximum ;21 ka (thousands of years ago), greatly affected the distributions and population sizes of temperate marine species as their ranges retreated southward to escape ice sheets. Traditional genetic models ...
Comparative phylogeography of northwest African Natrix maura (Serpentes: Colubr...
Barata, M.; Harris, D. J.; Castilho, RitaWhile the comparative phylogeography of European fauna is relatively well understood, with Pleistocene climatic oscillations leading to ‘southern refugia’ for many species, the equivalent pattern has not been determined for North Africa. In this context variation within North African populations of the riverine snake Natrix maura were assessed using mitochondrial DNA sequences. Recent literature regarding North...

A reassessment of the anamorphic fungus Fusicoccum luteum and description of it...
Phillips, A. J. L.; Fonseca, Filomena; Povoa, V.; Castilho, Rita; Nolasco, GustavoWhen Fusicoccum luteum was first described in 1985, it was not found sporulating in nature and its teleomorph was not known. Recently, a Botryosphaeria sp. was found on grapevines in Portugal, and the anamorph in culture resembled F. luteum. Nucleotide sequence of the nuclear rDNA internal transcribed spacer ITS2 distinguished isolates of this fungus from others in the B. dothidea complex, and the teleomorph, B...
Has time come for the genetic management of sea bass?
Volckaert, F.; Alvarez, M. C.; Argenton, F.; Bonhomme, F.; Chatain, B.; Colombo, L.; Castilho, Rita; Chevassus, B.; Gorshkova, G.; Kohler, M.Since 1980 the industrial production of European sea bass has risen considerably up to at least 18,000 MT in 1996 ( see also Josupeit, Aquaculture Europe 20(2):-12, 1995). This growth is remarkable since few were able to culture the species in the seventies. Several "classical" stages of development can be observed; they are typical of a rapidly expanding bioindustry.
