Ontogeny of swimming behaviour of two temperate clingfishes, Lepadogaster lepad...
Faria, Ana Margarida; Gonçalves, Emanuel JoãoGobiesocids are typically reef-dwelling species whose larvae have been found in several nearshore rocky environments; this suggests a possible retention pattern for these species. Retention may occur due to the physical features of an area and/or active larval behaviour, such as swimming abilities. In the laboratory, we measured the ontogeny of swimming behaviour (routine speed and critical speed, Ucrit) of 2 c...
Depth distribution of nearshore temperate fish larval assemblages near rocky su...
Beldade, Ricardo; Borges, Rita Alexandra; Gonçalves, Emanuel JoãoIn this study, we compare the composition, abundance and structure of a temperate fish larval assemblage at different depth intervals (0–4, 4–8 and 8–12 m) in the extreme nearshore environment. We used a plankton net attached to an underwater scooter to sample in close proximity to the rocky substrate (<50 cm). A total of 868 larvae from 27 taxa in 13 families were caught. The majority of larvae belonged to ben...
Embryonic and larval development of Lipophrys pholis (Pisces: Blenniidae)
Faria, Cláudia Barreiros Macedo de; Borges, Rita Alexandra; Gil, Fátima; Almada, Vítor Carvalho; Gonçalves, Emanuel JoãoInformation on the early ontogeny of Lipophrys pholis is scattered and incomplete. In this paper we describe for the first time the full developmental sequence from egg to juvenile in controlled conditions. In addition, some notes on the spawning behaviour of adults and the behaviour of larvae are provided. During oviposition, the female follows the male´s path, suggesting that the male may apply sperm on the n...
Etologia, ecologia e biologia da reprodução de blenióides - teleostei, blennioidei
Gonçalves, Emanuel JoãoTese de Doutoramento apresentada à Faculdade de Ciências, Universidade de Lisboa ; O presente trabalho pretendeu investigar alguns aspectos da ecologia, biologia da reprodução e comportamento de blenióides (Pisces: Blennioidei). Os machos de blenióides tipicamente guardam ovos em ninhos mais ou menos elaborados, onde as fêmeas vêm desovar. Defendem activamente o local de nidificação contra conspecíficos e outr...
A checklist of the blennioid fishes (Teleostei, Blennioidei) occurring in Portu...
Oliveira, Rui Filipe; Almada, Vítor Carvalho; Almeida, Armando J.; Santos, Ricardo Serrão; Gonçalves, Emanuel JoãoTwenty species of blennioide fishes have been cited from Portuguese waters. A survey of the published literature and personal observations by the authors allowed to confirm the presence of eighteen species: Clinitrachus argentatus, Labrisomus nuchipinnis, Tripterygion delaisi, Blennius ocellaris, Coryphoblennius galerita. Lipophrys canevae, L. dalmatinus, L. pholis, L. trigloides, Parablennius gattorugine, P. p...
