Multigene Molecular Systematics Confirm Species Status of Morphologically Conve...
Silva, Joana Matzen da; Santos, Antonina dos; Cunha, Marina R.; Costa, Filipe O.; Creer, Simon; Carvalho, Gary R.Introduction: In spite of contemporary morphological taxonomy appraisals, apparent high morphological similarity raises uncertainty about the species status of certain Pagurus hermit crabs. This is exemplified between two European species, Pagurus excavatus (Herbst, 1791) and Pagurus alatus (Fabricius 1775), whose species status is still difficult to resolve using morphological criteria alone. Methodology/Princ...
Are sardine larvae caught off northern Portugal in winter starving? An approach...
Chícharo, Alexandra; Esteves, E.; Santos, A. M. P.; Santos, Antonina dos; Peliz, A.; Re, P.Recently, winter upwelling events off western Iberia have become more frequent. This may affect the production and survival of sardine eggs and larvae through increased offshore transport. By analysis of RNA:DNA ratios, we investigated the impact of winter upwelling events on the larval condition of Sardina pilchardus larvae as a function of oceanographic conditions and food availability. Larvae were collected ...
