Food web, taxonomy and functional level community response to large-scale bioge...
Sroczynska, Katarzyna; Pereira, Catia; Faisca, Pedro; Castillo-Escriva, Andres; Ribeiro, Sara; Raposeiro, Pedro; Ersoy, Zeynep; Araujo, MiguelFood webs are being increasingly used to predict ecosystem stability. The ultimate food web properties already account for the abiotic (environment) and biotic interactions (i.e. predator-prey interactions). While the importance of abiotic environment on a single taxonomical or functional diversity is being recognized, the role of environment in structuring trophic interactions is less explored. Additionally, f...
Combining eDNA metabarcoding and morphological-based approaches to increase res...
Pereira, Catia; Sroczynska, Katarzyna; Faisca, Pedro; Castillo-Escriva, Andres; Ribeiro, Sara; Ersoy, Zeynep; Raposeiro, Pedro; Gilbert, MTPEnvironmental DNA (eDNA) metabarcoding has the potential to improve aquatic biodiversity assessments by improving detection capability, taxonomic resolution and cost-effectiveness when compared to morphological- based approaches. Advances have been made in the field of metabarcoding, but challenges remain, including sensitivity of results to DNA extraction method and marker choice, and its dependency on often-i...
Diatoms from small ponds and terrestrial habitats in Deserta Grande Island (Mad...
Gonçalves, Vítor; Ritter, Catarina; Marques, Helena; Teixeira, Dinarte; Raposeiro, PedroFreshwater diversity, and diatoms in particular, from Desertas Islands (Madeira Archipelago, Portugal) is poorly known, although the Islands are protected and became a Natural Reserve in 1995. During two field expeditions in 2013 and 2014 to Deserta Grande Island, several freshwater and terrestrial habitats were sampled. The analysis of these samples aims to contribute to the biodiversity assessment of the fres...
Aquatic Hyphomycetes from streams on Madeira Island (Portugal)
Raposeiro, Pedro; Faustino, Hélder; Ferreira, Verónica; Gonçalves, VítorBackground Aquatic hyphomycetes are a phylogenetically heterogeneous group of fungi living preferentially in fast flowing, well-aerated forest streams. These fungi have worldwide distribution, but with the exception of Articulospora tetracladia, no aquatic hyphomycete taxon was previously recorded on Madeira Island. Aquatic hyphomycetes were sampled from 40 sites, distributed by 27 permanent streams in 2015, to...
