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...
Abundance-body mass relationships structuring aquatic food webs across biogeogr...
Ersoy, Zeynep; Castillo-Escriva, Andres; Pereira, Catia; Sroczynska, Katarzyna; Ribeiro, Sara; Araujo, Miguel; Matias, MiguelMost of the biological rates (growth, metabolic, reproduction) are greatly associated with body mass. Trophic interactions are also highly dependent on body mass due to feeding constraints. Scaling of body mass with abundance, known as size spectrum, provides information on community structure, energy flow, and ecosystem functioning. However, not many studies have incorporated individual body mass-abundance sca...
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...
