Reproductive traits of the African mud crab (Panopeus africanus) on the South P...
N. Monteiro, J.; Ovelheiro, Andreia; Pinto, Miguel; Teodosio, Maria; Leitão, FranciscoSpecies with high economic relevance are widely studied in contrast with low economic relevance species such as Panopeus africanus, a small crab with a wide distribution along the eastern Atlantic coast, which remains poorly studied in regarding to the biological and ecological issues. Knowledge of reproductive patterns is essential to understand populations dynamics and species biological life-cycle traits. Th...
Macro and microscopic maturation stage key of green crab (Carcinus maenas, Linn...
Ovelheiro, Andreia; N. Monteiro, J.; Gonçalves, Patrícia; Campinho, Marco António; Maia, Francisco; Teodosio, Maria; Leitão, FranciscoGonadal histology is a helpful tool to validate species' macroscopic maturity stages in fisheries biology. Regardless of the many studies on Carcinus maenas, there are still few concerning gonads tissue histology and description of maturity stages. In Portugal, information regarding this species' biology to help support the regulation of crab fisheries, including the minimum landing size, has not yet been defin...
Implications of warming on the morphometric and reproductive traits of the Gree...
N. Monteiro, J.; Bueno-Pardo, Juan; Pinto, Miguel; Pardal, Miguel A.; Martinho, Filipe; Miguel de Sousa Leitão, FranciscoUnderstanding the relationship between environmental temperature and the biological traits of organisms is fundamental to inferring the potential impacts of climate change. In the case of marine poikilotherm species, seawater temperature is one of the main driving forces of biological processes, with consequences at higher levels of organization such as population and ecosystem. In this study, we analysed diffe...
Eco-socio-economic vulnerability assessment of Portuguese fisheries to climate ...
Pinto, Miguel; Albo-Puigserver, Maria; Bueno-Pardo, Juan; N. Monteiro, J.; Teodosio, Maria; Leitão, FranciscoUnderstanding ecological, and socio-economical vulnerabilities is fundamental towards developing and implementing regional adaptation strategies to climate change. The Portuguese coast is situated in a transition zone between temperate ecosystems to the north, and subtropical with Mediterranean characteristics, to the south, with distinct oceanographic regions (north, centre, and south), fish assemblages and so...
Ecological sensitivity and vulnerability of fishing fleet landings to climate c...
Albo Puigserver, Marta; Bueno-Pardo, Juan; Pinto, Miguel; N. Monteiro, J.; Ovelheiro, Andreia; Teodosio, Maria; Leitão, FranciscoThe degree of exposure of fishing communities to environmental changes can be partially determined by the vulnerability of the target species and the landings composition. Hence, identifying the species that ecologically most contribute to the vulnerability of the landings are key steps to evaluate the risk posed by climate change. We analyse the temporal variability in intrinsic sensitivity and the ecological ...
Variability in Carcinus maenas Fecundity Along lagoons and estuaries of the Por...
N. Monteiro, J.; Ovelheiro, Andreia; Ventaneira, Ana M.; Vieira, Vasco; Teodosio, Maria; Leitão, FranciscoAlthough Carcinus maenas as a species is widely studied, research focusing on fecundity is still scarce. The main objective of this study was to evaluate size-fecundity relationships across diferent lagoons and estuaries, along the Portuguese coast, to understand how the local environment afects reproductive patterns. Between 2019 and 2020, ovigerous females were collected from the Southern (Ria Formosa and Ria...
Influence of oceanic and climate conditions on the early life history of Europe...
Pinto, Miguel; N. Monteiro, J.; Crespo, D.; Costa, F.; Rosa, J.; Primo, A. L.; Pardal, M. A.; Martinho, F.Understanding how marine fish early-life history is affected in the long-term by environmental and oceanographic factors is fundamental given its importance to population dynamics and connectivity. This work aimed at determining the influence of these processes on the interannual variability in hatch day and early-life growth patterns of European seabass, over a seven-year period (2011-2017) in the Atlantic Ibe...
