Relação entre atividade física e atividade sexual em alunos universitários
Gonçalves, Emanuel; Antunes, Melissa; Leite, Rafael; Pinto, Teresa; Pereira, Beatriz OliveiraA atividade física tem uma relação inversa com as doenças degenerativas, onde o exercício físico tem sido indicado na prevenção de doenças cardiovasculares e músculo esqueléticas, bem como na prevenção de outras doenças degenerativas. No entanto, a maioria dos estudos têm priorizado o efeito do exercício em diversas disfunções metabólicas, dando-se pouca ou nenhuma atenção à função sexual. O presente estudo tem...
Optimization approaches for the in silico discovery of optimal targets for gene...
Gonçalves, Emanuel; Pereira, Rui; Rocha, I.; Rocha, MiguelMetabolic engineering (ME) efforts have been recently boosted by the increase in the number of annotated genomes and by the development of several genome-scale metabolic models for microbes of interest in industrial biotechnology. Based on these efforts, strain optimization methods have been proposed to reach the best set of genetic changes to apply to selected host microbes, in order to create strains that are...
Computational tools for strain optimization by tuning the optimal level of gene...
Gonçalves, Emanuel; Rocha, I.; Rocha, MiguelIn this work, a plug-in for the OptFlux Metabolic Engineering platform is presented, implementing methods that allow the identification of sets of genes to over/under express, relatively to their wild type levels. The optimization methods used are Simulated Annealing and Evolutionary Algorithms, working with a novel representation and operators. This overcomes the limitations of previous approaches based solely...
A software platform for evolutionary computation with pluggable parallelism and...
Evangelista, Pedro; Gonçalves, Emanuel; Sobral, João Luis; Pinho, Jorge; Maia, Paulo; Rocha, MiguelThis paper proposes the Java Evolutionary Computation Library (JECoLi), an adaptable, flexible, extensible and reliable software framework implementing metaheuristic optimization algorithms, using the Java programming language. JECoLi aims to offer a solution suited for the integration of Evolutionary Computation (EC)-based approaches in larger applications, and for the rapid and efficient benchmarking of EC al...
Effects of starvation on swimming performance and body condition of pre-settlem...
Faria, Ana Margarida da Silva; Chícharo, Alexandra; Gonçalves, EmanuelBody condition in larval fishes is an important determinant of survival in the natural environment. However, few studies correlate body condition with behavioural traits critical for survival, such as swimming performance. In the present study, we compared normally fed larvae of gilthead seabream Sparus aurata Linnaeus, 1758, at various intervals post-hatch with larvae which were starved for 1 to 3 d (for Ucrit...
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...
