Environmental DNA Template Variation: Its Relevance for Species Detection and C...
Nogueira, Sofia; Curto, Manuel; Dias, Diogo; Alves, Maria Judite; Amaral, Susana Dias; Magalhaes, Maria Filomena; Carrapato, Carlos; Veríssimo, AnaAccurate species monitoring is foundational for understanding and assessing species extinction risk. Environmental DNA (eDNA) based species detection methods have been proposed as fast and powerful biodiversity monitoring tools. Yet, these methods are susceptible to errors that might hinder the assessment of species extinction risk. Samples may contain low DNA concentrations of the target taxa and/or exhibit hi...
The mitochondrial genomes of Iberian freshwater and diadromous fishes
Veríssimo, Joana; Curto, Manuel; Alves, Maria Judite; de Almeida, Pedro Raposo; Aparicio, Enric; Clavero, Miguel; Chaves, CátiaThe Iberian Peninsula, in southwestern Europe, is home to a distinctive freshwater fish fauna, predominantly composed of endemic species. This is a consequence of the prolonged isolation from western Europe caused by the Pyrenees, the diverse geological and climatic gradients, and the isolation of river basins. Freshwater and diadromous fishes have diversified in the Iberian Peninsula and include 72 currently r...
Local environment and fragmentation by drought and damming shape different comp...
Martelo, Joana; Gkenas, Christos; Ribeiro, Diogo; Alves, Maria Judite; Ribeiro, Filipe; Cucherousset, Julien; Gago, João; Magalhaes, Maria FilomenaPool refuges are critical for maintaining stream fish diversity in increasingly intermittent streams. Yet, the patterns and drivers of beta diversity of native and non-native fish in pool refuges remain poorly known. Focusing on Mediterranean streams, we decomposed beta diversity of native and non-native fish into richness difference (RichDiff) and species replacement (Repl), and local (LCBD, LCBDRichDiff and L...
Habitat selection and foraging success by an endangered Mediterranean cyprinid:...
Martelo, Joana; Grossman, Gary D.; Magalhaes, Maria FilomenaHabitat loss and degradation are causing collapses in freshwater fish in the Mediterranean region, where habitat restoration actions are still hampered by poor understanding of fish habitat selection and fitness. Here, we combined field surveys and laboratorial experiments to investigate how water velocity, body size and intra-specific interactions influence habitat selection and foraging success by the highly ...
Species richness and distribution of the largest plant radiation of Angola: Eup...
Frazão, Raquel; Catarino, Silvia; Goyder, David; Darbyshire, Iain; Magalhaes, Maria Filomena; Romeiras, Maria M.Knowledge of species richness and distribution of African biodiversity comes primarily from fauna studies, despite the tremendous richness of the flora. The genus Euphorbia (Euphorbiaceae) is one of the most diverse plant genera, and shows a great diversity across Africa. This genus is the largest endemic plant radiation in Angola, including 82 native species with a large diversity of life forms (e.g. herbs, sh...
