Molecular insights into spined loaches (Cobitidae: Cobitis) reveal the complex ...
Perdices, Anabel; Queirós, João; Alves, Maria Judite; Alves, Paulo Célio; Beja, Pedro; Buckley, David; Clavero, Miguel; Coelho, Maria ManuelaPalaeogeographic and tectonic rearrangements of rivers have significantly influenced the phylogeography of Iberian and North African freshwater fishes, but their impact remains unclear. We revisit the phylogeographic relationships and diversification timelines of Cobitis (spined loaches, family Cobitidae) on both sides of the Strait of Gibraltar. Sampling 230 sites across 41 river basins, we analysed genetic va...
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...

Using individual-based demographic modelling to estimate the impacts of anthrop...
Marques, Teresa; Crispim-Mendes, Tiago; Palma, Luís; Pita, Ricardo; Moreira, Francisco; Beja, PedroWildlife anthropogenic mortality is increasing worldwide, yet there is limited understanding regarding its population-level impacts. Territorial species stand out in this context, as they possess distinctive characteristics that are often overlooked but may significantly affect their vulnerability. In particular, population impacts may depend on the level and spatial distribution of additional mortality risk ac...
Patch spatial attributes and time to disturbance affect the emergence of source...
Crispim-Mendes, Tiago; Roos, Deon; Ferreira, Clara; Paupério, Joana; Silva, João Paulo; Godinho, Sérgio; Alves, Paulo Célio; Mira, António; Beja, PedroUnderstanding the demography of local populations within ephemeral habitat patches is crucial for effective local (site-based) conservation management in spatially and temporally heterogeneous environments. Evidence suggests that species persisting in networks of ephemeral patches often exhibit source-sink dynamics, where certain local populations act as temporary sources at some time between initial colonizati...

Dietary metabarcoding reveals the simplification of bird-pest interaction netwo...
da Silva, Luís P.; Mata, Vanessa A; Lopes, Pedro B.; Pinho, Catarina J; Chaves, Catia; Correia, Edna; Pinto, Joana; Heleno, Ruben; Timóteo, SérgioAgriculture is vital for supporting human populations, but its intensification often leads to landscape homogenization and a decline in non-provisioning ecosystem services. Ecological intensification and multifunctional landscapes are suggested as nature-based alternatives to intensive agriculture, using ecological processes like natural pest regulation to maximize food production. Birds are recognized for thei...
