Biological traits and population dynamics for sustainable harvesting of Carcinu...
Monteiro, João Nuno; Ovelheiro, Andreia; Maia, Francisco; Teodosio, Maria; Leitão, FranciscoResearch focusing on the biological patterns and population dynamics of Carcinus maenas has not been conducted for the purpose of fishery management along the European coastal systems. This has led to the implementation of fisheries management policies without scientific considerations, adversely affecting fishery profitability. To addrees this gap, we studied the crab species' population dynamics, reproductive...
Impact and size selectivity of fishing gears used in estuarine crab fisheries
Monteiro, João Nuno; Ovelheiro, Andreia; Teodosio, Maria; Leitão, FranciscoCrustacean fisheries have expanded in the last decade due to the high economic value of the species. However, estuarine crustacean fisheries remain poorly studied compared with marine crustacean fisheries. In Portugal, the European green crab ( Carcinus maenas) may become increasingly important for the fishing industry and seafood production in general, especially in the current context of overexploitation of e...
The role of management on gender (in) equality and offensive behaviors in highe...
Sobral, Tiago; Vieira dos Santos, Joana; Giger, Jean-Christophe; Teodosio, MariaDespite the numerical predominance of women in higher education institutions (HEIs), significant underrepresentation in academic and leadership positions persists, highlighting ongoing gender inequalities. This study examines the role of management in addressing gender disparities and offensive behaviors within a Portuguese public HEI, using psychosocial safety climate (PSC) theory as a conceptual framework. We...
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...
Neotropical dragonflies (Insecta: Odonata) as key organisms for promoting commu...
Guerrero-Moreno, Mayerly Alexandra; Juen, Leandro; Puig-Cabrera, Miguel; Teodosio, Maria; Oliveira-Junior, José Max BarbosaIncorporating insects into ecotourism activities increases awareness of their importance in ecosystems. However, the inclusion of this group in ecotourism activities is still rare. In this context, we identified the perception of indigenous and non-indigenous leaders and residents about the potential of Odonata (dragonflies and damselflies) as key organisms for promoting community- based ecotourism (CBET) in th...
The arrival of a non-indigenous ecosystem engineer to a heavily invaded and flo...
Encarnação, João; Teodosio, Maria; Morais, PedroEcosystem engineering bivalves can shape aquatic ecosystems because their high filtration capacity changes water quality and their shells increase the fractal dimension of benthic ecosystems with consequent abiotic and biotic effects. The Asian date mussel Arcuatula senhousia (W. H. Benson, 1842), native to East Asia between the South China Sea and Siberia, is one such bivalve that, despite its small size, can ...
Sustainable harvesting alone cannot prevent decline of the green crab fishery i...
Monteiro, João Nuno; Roa-Ureta, Ruben; Ovelheiro, Andreia; Teodosio, Maria; Leitão, FranciscoEstuarine fisheries are of high regional socio-economic importance worldwide, by providing an important livelihood for many families. The Portuguese green crab (Carcinus maenas) fishery was assessed using a socio-economic assessment to understand the importance of the fishery and a stock assessment analysis to determine the exploitation status of the fishery during 1960-2020. Fisher knowledge revealed that crab...
Socioeconomic importance of the small-scale Mud Crab fishing (Scylla Serrata, F...
Manuessa, Bonifácio; Cuinhane, Calmila J. O.; Borges, Teresa Cerveira; Teodosio, Maria; Leitão, FranciscoMud crab fishing (Scylla serrata) is an important activity contributing to the livelihood of coastal communities in Mozambique. The abundance of this crab and the increase in international companies in the region that exclusively buy crabs and export to the Asian market have caused fisheries to gain local importance in recent years. The present study evaluates the socioeconomic importance of mud crab fishing an...
Dataset of the complete mitogenome of the deep-sea sailfin roughshark, Oxynotus...
Matos, Ana; Gomes-dos-Santos, André; Graça Aranha, Sofia; Dias, Ester; Veríssimo, Ana; Teodosio, Maria; Figueiredo, Ivone; Castro, L. Filipe C．Chondrichthyans comprise a diverse group of vertebrate species with extraordinary ecological relevance. Yet, multiple members of this evolutionary lineage are associated with sig-nificant extinction risk. The sailfin roughshark Oxynotus para-doxus is a deep-water benthic shark currently listed as vul-nerable due to population declines in parts of its range. Here we provide the first complete mitochondrial genom...
Characterising different artisanal fishing gears catches that operate in distin...
Jeremias J. Mocuba; Eudriano F.S. Costa; Daniel Oliveira Mualeque; Maria Alexandra Teodósio; Francisco Leitão; Mocuba, JeremiasMonitoring the ichthyofauna is crucial to detect changes in aquatic communities for fisheries management and conservation. This study aimed to identify the most effective gear for ichthyofauna studies in the estuary. Thus, the performance of the beach seine (active gear) and chicocota (fixed gear), common fishing gears used by artisanal fishers in the Bons Sinais estuary (BSE), were used to characterise fish as...
