Effects of the invasion of riparian forest by Acacia spp. trees on leaf litter ...
Ferreira, Verónica; Pereira, AnaStreams depend on riparian forests (for example, as a source of plant detritus that sustains aquatic communities), therefore, they are susceptible to changes in the species that compose them. The riparian forests in central Portugal are threatened by invasive species, including species of the Acacia genus that have characteristics distinct from those of native species. In recent years, several studies have been...
Macroplastic litter colonization by stream macroinvertebrates relative to that ...
Ferreira, VerónicaEnvironmental pollution by anthropogenic litter is a global concern, but studies specifically addressing the interaction between macroplastics and macroinvertebrates in streams are scarce. However, several studies on plant litter decomposition in streams have also used plastic strips as a methodological approach to assess if macroinvertebrates colonize plant litter mostly as a substrate or a food resource. Look...
Comparing the sensitivity of aquatic organisms relative to Daphnia sp. toward e...
Afonso, Sandra; Ferreira, Verónica; Moreira-Santos, MatildeInterest on aromatic and medicinal plants (AMP)-based products, especially crude extracts (CE) and essential oils (EO), has increased over recent years due to their bioactive and biopesticide properties, though a variety of these compounds is environmentally damaging. Aquatic organisms can easily be exposed to the toxicological risks of AMP-based products, but research exploring existing ecotoxicity data to non...
Breeding Alnus species for resistance to Phytophthora disease in the Iberian Pe...
Cordeiro, Daniela; Pizarro, Alberto; Vélez, M. Dolores; Guevara, M. Ángeles; Marıa, Nuria de; Ramos, Paula; Cobo-Simón, Irene; Diez-Galán, AlbaAlders are widely distributed riparian trees in Europe, North Africa and Western Asia. Recently, a strong reduction of alder stands has been detected in Europe due to infection by Phytophthora species (Stramenopila kingdom). This infection causes a disease known as alder dieback, characterized by leaf yellowing, dieback of branches, increased fruit production, and bark necrosis in the collar and basal part of t...
The ADnet Bayesian belief network for alder decline: Integrating empirical data...
Gomes Marques, Inês; Vieites-Blanco, Cristina; Rodríguez-González, Patricia M.; Segurado, Pedro; Marques, Marlene; Barrento, Maria J.The globalization in plant material trading has caused the emergence of invasive pests in many ecosystems, such as the alder pathogen Phytophthora ×alni in European riparian forests. Due to the ecological importance of alder to the functioning of rivers and the increasing incidence of P. ×alni-induced alder decline, effective and accessible decision tools are required to help managers and stakeholders control t...

Barreto, Guilherme; Ferreira, VerónicaOs ribeiros constituem a maioria dos cursos de água numa bacia hidrográfica. Nos ribeiros de floresta, os detritos vegetais produzidos pela vegetação circundante suportam grande parte da vida aquática, já que a produção primária é limitada pelo ensombramento. Os invertebrados fragmentadores têm um papel fundamental na decomposição destes detritos, no ciclo de nutrientes, e servem como ligação a outros níveis da...
A meta-analysis of drought effects on litter decomposition in streams
Ferreira, Verónica; Graça, Manuel, A. S.; Elosegi, ArturoDroughts, or severe reductions of water flow, are expected to become more frequent and intense in rivers in many regions under the ongoing climate change scenario. It is therefore important to understand stream ecosystem functioning under drought conditions. We performed a meta-analysis of studies addressing drought effects on litter decomposition in streams (50 studies contributing 261 effect sizes) to quantif...
Global negative effects of drought on instream invertebrate communities
Yang, Qiao; Ferreira, Verónica; Wu, Qiqian; Heděnec, Petr; Day, Yuan-Ji; Yuan, Chaoxiang; Peng, Yan; Wu, Fuzhong; Yue, KaiGlobal climate change has led to more frequent and severe droughts, which can negatively affect instream invertebrate communities, but we lack a perspective on the global patterns and drivers of such drought effects. Here, using meta-analysis, we synthesized 997 paired observations extracted from 94 peer-reviewed publications to assess how drought affects the biomass, density, taxonomic richness, and diversity ...
The past is (not) another country: discursive dynamics and representations of t...
Ferreira, VerónicaThis chapter aims to map a part of the digital mnemonic circuit for the colonial war. Starting with an analysis of blogs – the first platform to host (re)creations and (re)writings of the memories of war veterans – before moving on to the labyrinthine paths of Facebook, the aim will be to trace the social representations, narratives, and discursive dynamics associated with the colonial war that are present in P...
