Assessment of male reproductive traits in endangered leuciscids from the Iberia...
Hernandez, Ana; Sousa-Santos, Carla; Gil, Fátima; Cabrita, Elsa; Guerreiro, Pedro; Gallego, VictorDuring the spring of 2022, several endangered leuciscid species (Anaecypris hispanica, Squalius aradensis, Anachondrostoma Occidentale, and Iberochondrostoma lusitanicum) were sampled both at the Vasco da Gama aquarium facilities and in some rivers of the Algarve region, Portugal. Sperm samples were extracted by gentle abdominal pressure and sperm motion parameters were assessed for the first time in four speci...
Building a Portuguese Coalition for Biodiversity Genomics
Marques, João Pedro; ALVES, Paulo C; Rosário, Isabel Amorim do; Lopes, Ricardo J.; Moura, Mónica; Meyers, Gene; Sim-Sim, Manuela; Sousa-Santos, C.The diverse physiography of the Portuguese land and marine territory, spanning from continental Europe to the Atlantic archipelagos, has made it an important repository of biodiversity throughout the Pleistocene glacial cycles, leading to a remarkable diversity of species and ecosystems. This rich biodiversity is under threat from anthropogenic drivers, such as climate change, invasive species, land use changes...
Aeromonas spp. Prevalence, virulence, and antimicrobial resistance in an ex sit...
Grilo, Miguel; Amaro, Guadalupe; Chambel, Lélia; Marques, Carolina S.; Marques, Tiago A.; Gil, Fátima; Sousa-Santos, Carla; Robalo, JoanaEx situ breeding programs are important conservation tools for endangered freshwater fish. However, developing husbandry techniques that decrease the likelihood of disease, antimicrobial resistance, and virulence determinants acquisition during this process is challenging. In this pilot study, we conducted a captivity experiment with Portuguese nase (Iberochondrostoma lusitanicum), a critically endangered leuci...

Physiological effects of cymothoid parasitization in the fish host Pomatoschist...
Cereja, Rui; Mendonça, Vanessa; Dias, Marta; Vinagre, Catarina; Gil, Fátima; Diniz, MárioCurrently, the effects of global warming on marine organisms are widely recognized by the scientific community. However, studies that relate the increase in ocean temperature with other stress factors are still scarce. The main aim of this study was to evaluate the effects of water temperature increase on the parasite Anilocra frontalis, the parasite’s effects over its host Pomatoschistus microps. Therefore, P....
Preliminary SEM studies on normal and altered gonads of Catostylus tagi
Lisboa, Raquel; Nogueira, Isabel; Gil, Fátima; Mascarenhas, Paulo; Morais, ZildaPoster apresentado nas II Jornadas Nacionais de Caracterização de Materiais. 24-26 de Janeiro de 2017, Aveiro, Portugal; "Catostylus tagi, the sole European Catostylidae, is an edible Scyphozoa which occurs in summer at Tagus and Sado estuaries. Some aspects of its application in health sciences have already been studied. To start the study of its life cycle, the characterization of gonads regarding size and se...
Preliminary studies on the lifecycle of Catostylus tagi: differentiation betwee...
Lisboa, Raquel; Mascarenhas, Paulo; Gil, Fátima; Ruano, Francisco; Ladeira, Carina; Morais, ZildaPoster presented at the 2nd International Congress of CiiEM: “Translational Research and Innovation in Human in health Sciences”. Egas Moniz, Caparica, 11-13 June 2017; Jellyfish has been proposed as a source in drug development to treat diseases such as arthritis and hypertension. Catostylus tagi, the sole European Catostylidae, is an edible Scyphozoa which occurs in summer at Tagus and Sado estuaries. Some as...

A comparison between the ontogeny of two related blenniid species Parablennius ...
Faria, Cláudia Barreiros Macedo de; Gil, Fátima; Santos, Ricardo Serrão; Almada, Vítor CarvalhoParablennius gattorugine and Parablennius ruber are closely related sympatric western European species. In this note, traits that distinguish the larvae of both species are presented and it is demonstrated that conflicting descriptions reported in the literature on the larvae of P. gattorugine stem from confusion between the two species.
An efficient technique for the captive breeding of an endangered freshwater fis...
Gil, Fátima; Faria, Cláudia Barreiros Macedo de; Almada, Vítor CarvalhoSalaria fluviatilis is one of the few freshwater members of the family Blenniidae and occurs around the Mediterranean Basin. This species is vulnerable or endangered in most countries where it occurs. Thus, information on its developmental biology and the establishment of methods for ex situ reproduction of highly endangered populations, to preserve them until natural habitats are restored, are much needed. A t...
