Citizen science as a monitoring tool in aquatic ecology: trends, gaps, and futu...

Lameira, Helton Luis Nina; Guerrero-Moreno, Mayerly Alexandra; Silva, Everton Cruz da; Oliveira, Fernando Abreu; Teodosio, Maria; Dias-Silva, Karina

Aquatic ecosystems are essential for biodiversity and ecosystem services, but anthropogenic pressures threaten them. In this context, citizen science has emerged as an innovative strategy for biodiversity conservation and environmental monitoring. We conducted a scientometric analysis to identify patterns and gaps in the scientific literature on citizen science in aquatic ecology. We analyzed 185 articles publi...


Movement patterns of the invasive atlantic blue crab in a northeastern atlantic...

Encarnação, João Pedro da Silva; Morais, Pedro; Abecasis, David; Martínez Ramírez, Lucas; Barra, Melissa; Baptista, Vânia; Carere, Claudio

The movement ecology of invasive species discloses critical information to estimate ecological impacts and inform management policies to control their spread. The Atlantic blue crab Callinectes sapidus Rathbun, 1896, has successfully invaded coastal and estuarine ecosystems in southern Europe, making it urgent to understand fundamental aspects of its ecology in the non-native range. Recent studies identified ke...


Biological traits and population dynamics for sustainable harvesting of Carcinu...

Monteiro, João Nuno; Ovelheiro, Andreia; Maia, Francisco; Teodosio, Maria; Leitão, Francisco

Research 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...


The role of management on gender (in) equality and offensive behaviors in highe...

Sobral, Tiago; Vieira dos Santos, Joana; Giger, Jean-Christophe; Teodosio, Maria

Despite 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...


Reproduction traits and strategies of two Sardinella species off the Southwest ...

Quiatuhanga, Domingas; Morais, Pedro; Krug, Lilian; Teodosio, Maria

Small pelagic fishes such as Sardinella aurita (Valenciennes, 1847) and Sardinella maderensis (R. T. Lowe, 1838) are key intermediate-level components of the marine food web of the southwestern African coast. Their biomass off Angola has shown significant interannual variability, and information about their reproduction is insufficient in the region for adequate stock management. Thus, we aimed to unveil the re...


Trophic interactions of two sympatric small pelagic fishes off the southern coa...

Quiatuhanga, Domingas; Morais, Pedro; Teodosio, Maria

Numerous small pelagic fish species are of great economic importance and link the lower and upper levels of the marine food web. The round sardinella Sardinella aurita and flat sardinella S. maderensis coexist along their distribution range in the southeastern Atlantic Ocean, where we hypothesise that they compete for similar prey. Thus, this study aimed to compare the trophic ecology of these species off the s...


Citizen science from the perspective of Higher Education professors

Lameira, Helton Luis Nina; Guerrero-Moreno, Mayerly Alexandra; Silva, Everton Cruz; Santos, Paulo Roberto Brasil; Teodosio, Maria

Citizen science (CS) has the potential to be a crucial tool to effectively address positive contributions in the global context of the challenges of change in our societies and environment. Recent research highlights the growth of CS in formal education, but little is known about scientists’ perceptions. This study investigated the perception of 170 faculty members from 32 Brazilian federal universities regardi...


Impact and size selectivity of fishing gears used in estuarine crab fisheries

Monteiro, João Nuno; Ovelheiro, Andreia; Teodosio, Maria; Leitão, Francisco

Crustacean 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...


Sustainable harvesting alone cannot prevent decline of the green crab fishery i...

Monteiro, João Nuno; Roa-Ureta, Ruben; Ovelheiro, Andreia; Teodosio, Maria; Leitão, Francisco

Estuarine 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...


Reproductive traits of the African mud crab (Panopeus africanus) on the South P...

N. Monteiro, J.; Ovelheiro, Andreia; Pinto, Miguel; Teodosio, Maria; Leitão, Francisco

Species 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...
