Spatiotemporal patterns and environmental drivers of Physalia physalis strandin...
Carvalho, Patrícia; Cordeiro, Clara; Pereira, Soraia; Santos, Antonina dosPhysalia physalis is a cosmopolitan colonial organism frequently observed in Portuguese waters. The species has long tentacles, provided with cnidocytes, which release a strong poison when in contact with other organisms, and cause skin reactions and severe pain in humans. Events of rapid reproduction, common in these species, may have important economic and social consequences. This study explores for the firs...

Description of the complete larval development of Lysmata amboinensis (De Man) ...
Sousa, Lígia F. de; Marques, Daniel; Leandro, Sérgio; Santos, Antonina dosComplete larval morphological descriptions are currently only known for three of the 48 species of genus Lysmata. The present study describes and illustrates the larval development of Lysmata amboinensis (De Man) reared under laboratory conditions. Lysmata amboinensis larval development is composed by a total of ten zoea and a decapodite stage. The first zoeal stage larvae presents sessile eyes, a carapace with...
Catostylus tagi (Class: Scyphozoa, Order: Discomedusae, Suborder: Rhizostomida,...
Gueroun, Sonia K.M.; Torres, Tatiana M.; Santos, Antonina dos; Vasco Rodrigues, Nuno; Canning-Clode, João; Andrade, CarlosJellyfish proliferations, which are conspicuous and natural events, cause blooms that may lead to severe consequences for anthropogenic activities and ecosystem structure and functioning. Although research during the last decade has focused on factors influencing the different jellyfish life stages, few species currently have their full life cycle known. In this context, we describe for the first time the devel...
MarinEye - A tool for marine monitoring
Martins, Alfredo; Dias, André; Silva, Eduardo; Ferreira, Hugo; Dias, Ireneu; Almeida, José Miguel; Torgo, Luis; Gonçalves, Marco; Guedes, MaurícioThis work presents an autonomous system for marine integrated physical-chemical and biological monitoring – the MarinEye system. It comprises a set of sensors providing diverse and relevant information for oceanic environment characterization and marine biology studies. It is constituted by a physicalchemical water properties sensor suite, a water filtration and sampling system for DNA collection, a plankton im...

Lysmata jundalini, a new peppermint shrimp (Decapoda, Caridea, Hippolytidae) fr...
Rhyne, Andrew L.; Calado, Ricardo; Santos, Antonina dosA new peppermint shrimp species, Lysmata jundalini sp. nov., is described based on five specimens collected in shallow subtidal waters on Enrique Reef at the University of Puerto Rico, Mayagüez Isla, Magueyes Laboratories. Lysmata jundalini sp. nov. was identified from fresh material collected at the reef crest and back reef among coral rubble in June 2005 and April 2009. The new species is most closely related...
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...
Physical-biological interactions in the life history of small pelagic fish in t...
Santos, A. Miguel P.; Chicharo, Maria Alexandra Teodosio; Santos, Antonina dos; Moita, Teresa; Oliveira, P. B.; Peliz, A.; Re, P.This paper reviews relevant investigations conducted in the Western Iberia Upwelling Ecosystem (WIUE) on the dynamics of small pelagic fish (SPF), its relationship to climate changes and processes related to the ‘ocean triad’ (enrichment, concentration, transport/retention). In the last decades, a decline in the productivity of several SPF species (e.g., sardine and horse mackerel) was observed in the WIUE, whi...
Are sardine larvae caught off northern Portugal in winter starving? An approach...
Chicharo, Maria Alexandra; Esteves, E.; Santos, A. Miguel 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 sardines egss and larvae through increased offshore transport. By analysis of RNA: DNA ratios, we investigated the impact of winter upwelling events on the larval conditions of Sardina pilchardus larvaeas a function of oceanographic conditions and food availability. Larvae were collecte...
