The mitochondrial genomes of Iberian freshwater and diadromous fishes
Veríssimo, Joana; Curto, Manuel; Alves, Maria Judite; Almeida, Pedro Raposo de; 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...
Navigating Methodological Trade‐Offs in eDNA Metabarcoding Biodiversity Monitor...
Veríssimo, Joana; Lopes‐Lima, Manuel; Amaral, Fábio; Chaves, Cátia; Fernandes, Vasco; Kemanja, Mutaleni; Teixeira, Amilcar; Martins, Filipa M. S.Environmental DNA (eDNA) metabarcoding technologies promise significant advances in biodiversity monitoring, yet their application requires extensive optimisation and standardisation. Recent research demonstrated that increased sampling and analytical efforts are needed to improve biodiversity estimates, though fully optimising study designs is often hindered by resource constraints. Consequently, researchers m...

The InBIO Barcoding Initiative Database: DNA barcodes of Portuguese moths
Ferreira, Sónia; Corley, Martin F. V.; Nunes, João; Rosete, Jorge; Vasconcelos, Sasha; Mata, Vanessa A.; Veríssimo, Joana; Silva, Teresa L; Sousa, PedroThe InBIO Barcoding Initiative (IBI) Dataset - DS-IBILP08 contains records of 2350 specimens of moths (Lepidoptera species that do not belong to the superfamily Papilionoidea). All specimens have been morphologically identified to species or subspecies level and represent 1158 species in total. The species of this dataset correspond to about 42% of mainland Portuguese Lepidoptera species. All specimens were col...
The InBIO Barcoding Initiative Database: DNA barcodes of Orthoptera from Portugal
Pina, Sílvia; Pauperio, Joana; Barros, Francisco; Chaves, Cátia; Martins, Filipa MS; Pinto, Joana; Veríssimo, Joana; Mata, Vanessa A; Beja, PedroThe InBIO Barcoding Initiative (IBI) Orthoptera dataset contains records of 420 specimens covering all the eleven Orthoptera families occurring in Portugal. Specimens were collected in continental Portugal from 2005 to 2021 and were morphologically identified to species level by taxonomists. A total of 119 species were identified corresponding to about 77% of all the orthopteran species known from continental P...
Multi-species occupancy modeling reveals methodological and environmental effec...
Peixoto, Sara; Mota-Ferreira, Mário; Chaves, Cátia; Velo-Antón, Guillermo; Beja, Pedro; Egeter, BastianAquatic environmental DNA is increasingly used for biodiversity monitoring, such as surveying threatened and invasive species. Mainstreaming these methods in practi- cal applications, however, still requires significant standardization and optimisation, namely regarding DNA capture methods. Here we evaluated how filter type (standard disc filters vs high-capacity capsules), number of sampling sites, volume of w...
Species detection from aquatic eDNA: assessing the importance of capture methods
Peixoto, Sara; Chaves, Cátia; Velo-Antón, Guillermo; Beja, Pedro; Egeter, BastianEnvironmental DNA (eDNA) is increasingly used for biodiversity monitoring, particularly in aquatic systems. However, each step, from sample collection to bioinformatic analysis, can introduce biases and influence the reliability of results. While much effort has been put into the optimization of laboratory methods, less attention has been devoted to estimate the impacts of eDNA capture methods. To address this ...
The InBIO barcoding initiative database: DNA barcodes of portuguese Hemiptera 01
Sousa, Pedro; Grosso-Silva, José Manuel; Andrade, Rui; Chaves, Cátia; Pinto, Joana; Paupério, Joana; Beja, Pedro; Ferreira, SóniaBackground The InBIO Barcoding Initiative (IBI) Hemiptera 01 dataset contains records of 131 specimens of Hemiptera. Most specimens have been morphologically identified to species or subspecies level and represent 88 species in total. The species of this dataset correspond to about 7.3% of continental Portuguese hemipteran species diversity. All specimens were collected in continental Portugal. Sampling took pl...
DNA barcoding of portuguese lacewings (Neuroptera) and snakeflies (Raphidiopter...
Oliveira, Daniel; Chaves, Cátia; Pinto, Joana; Paupério, Joana; Fonseca, Nuno; Beja, Pedro; Ferreira, SóniaThe orders Neuroptera and Raphidioptera include the species of insects known as lacewings and snakeflies, respectively. In Portugal, these groups account for over 100 species, some of which are very difficult to identify by morphological analysis. This work is the first to sample and DNA sequence lacewings and snakeflies of Portugal. A reference collection was built with captured specimens that were identified ...
