Engaging children in geosciences through storytelling and creative dance
Matias, Ana Catarina; Carrasco, A. Rita; Ramos, Ana A.; Borges, R.Natural sciences have traditionally been disseminated in outreach activities as formal, one-way presentations. Nevertheless, innovative strategies are being increasingly developed using arts, gaming, and sketching, amongst others. This work aimed at testing an alternative and innovative way to engage non-expert audiences in ocean and coastal geology through a combination of scientific concept explanations and c...
Investigation of surface silver enrichment in ancient high silver alloys by PIX...
Borges, R.; Alves, L; Silva, R; Araujo, M; Candeias, A; Corregidor, V; Valerio, P; Barrulas, PedroSurface elemental analysis presenting high silver (Ag) contents have been regarded as reliable for original bulkcomposition of silver coins which are accordingly referredas being produced from very pure Ag alloys. Also, the ex-tent in which the surface elemental composition analytical results are influenced by surface Ag enrichment hasbeen disregarded in coins alloys with Agfinenesses greater than the Ag conten...
Larval development and allometric growth of the black-faced blenny Tripterygion...
Solomon, F. N.; Rodrigues, D.; Gonçalves, E. J.; Serrão, E. A.; Borges, R.Larval development and allometric growth patterns of the black-faced blenny Tripterygion delaisi are described from a larval series (body length, L-B = 3.30-12.10 mm) caught by light traps at the Arrabida Marine Park, Portugal. Larvae of T. delaisi possess distinctive morphometric and meristic characteristics which can be used to identify this species from related taxa. Pigmentation is sparse but characteristic...
High interannual variability in connectivity and genetic pool of a temperate cl...
Klein, Maria; Teixeira, Sara; Assis, J.; Serrão, Ester; Gonçalves, Emanuel J.; Borges, R.Adults of most marine benthic and demersal fish are site-attached, with the dispersal of their larval stages ensuring connectivity among populations. In this study we aimed to infer spatial and temporal variation in population connectivity and dispersal of a marine fish species, using genetic tools and comparing these with oceanographic transport. We focused on an intertidal rocky reef fish species, the shore c...
Early life history of larvae and early juvenile Atlantic horse mackerel Trachur...
Van Beveren, Elisabeth; Klein, Maria; Serrão, Ester; Gonçalves, Emanuel J.; Borges, R.Early life history traits (ELHTs) are key to understand recruitment patterns in marine animals. However, for reef fishes, studies on ELHTs are mainly focused on tropical systems and little is known for temperate reefs. In this study we used SMURFs (Standard Monitoring Units for the Recruitment of Reef Fishes) to collect fish in a temperate rocky reef system (Arrabida Marine Park, Portugal) on a weekly basis for...
Biomares, a LIFE project to restore and manage the biodiversity of Prof. Luiz S...
Cunha, A. H.; Erzini, Karim; Serrão, Ester; Gonçalves, E.; Borges, R.; Henriques, M.; Henriques, Victor; Guerra, M.; Duarte, C.; Marba, N.; Fonseca, MThe Marine Park Prof. Luiz Saldanha, in the coast of Arrabida, is the first marine park in continental Portugal. This area is a Nature 2000 site and is considered to be a hotspot for European marine biodiversity. In 2005, the management plan of the park was implemented, ending several habitat menaces, thereby allowing an application to the LIFE-NATURE Programme. The LIFE-BIOMARES project aimed at the restoratio...
Characterization of 15 polymorphic microsatellite loci in the temperate reef fi...
Teixeira, Sara; Candeias, Rui; Klein, Maria; Serrão, Ester; Borges, R.Abstract The clingfish, Lepadogaster lepadogaster is a reef fish species, abundant in temperate nearshore rocky reefs of the Eastern Atlantic and central and Eastern Mediterranean. To study genetic variability and population connectivity of this species, we developed fifteen polymorphic microsatellite markers. These were tested in one population and all but one, showed no departure from Hardy–Weinberg equilibri...
Short-term temporal fluctuation of very-nearshore larval fish assemblages at th...
Borges, R.; Vaz, J.; Serrão, Ester; Gonçalves, E. J.Understanding processes affecting fish recruitment and population connectivity is of major importance to the management of Marine Protected Areas. Fluctuations in recruitment of coastal fishes can be affected by processes occurring during the early life stages such as the dispersal and availability of larvae. In nearshore temperate environments, there is a lack of knowledge about the patterns of larval supply o...
Horizontal spatial and temporal distribution patterns of nearshore larval fish ...
Borges, R.; Ben-Hamadou, Radhouan; Chicharo, Maria Alexandra Teodosio; Re, P.; Gonçalves, Emanuel J.There have been no previous studies of the composition of nearshore larval fish assemblages along the coast of Portugal. We aimed to describe the composition and horizontal distribution patterns of larval fish assemblages and their temporal dynamics near a rocky reef at depths shallower than 13 m (inshore) and at two miles (3.70 km) from shore (offshore), as well as along transects perpendicular to the shorelin...
Short-term social modulation of 11-ketotestosterone urinary levels in males of ...
Borges, R.; Oliveira, R. F.; Almada, V. C.; Canario, Adelino V. M.After 48 hours social isolation, male individuals of Oreochromis mossambicus wera allowed to interact with a conspecifif female in the same aquarium during a period of six hours.
