Nota introdutória

Response of the egg parasitoids of the pine processionary moth to host density ...

Thaumetopoea pityocampa is the most important pine defoliator in the Mediterranean 24 basin. Despite being attacked by a number of natural enemies, populations occur 25 frequently at high density in several areas. 26 2 Egg parasitism was studied in 27 pine and cedar forests in Algeria, in relation to the host 27 density (tents per tree) and the proportion of forest cover in the landscape. 28 3 Egg parasitism va...

Assessing the connectivity of riparian forests across a gradient of human distu...

The connectivity of riparian forests can be used as a proxy for the capacity of riparian zones to provide ecological functions, goods and services. In this study, we aim to test the potential of the freely available Copernicus “Riparian Zones” dataset to characterize the connectivity of riparian forests located in two European bioclimatic regions—the Mediterranean and the Central Baltic hydroregions—when subjec...

Riparian Ecological Infrastructures: Potential for Biodiversity-Related Ecosyst...

Riparian Ecological Infrastructures are networks of natural and semi-natural riparian areas located in human-dominated landscapes, crucial in supporting processes that directly or indirectly benefit humans or enhance social welfare. In this study, we developed a novel multimetric index, termed Habitat Ecological Infrastructure’s Diversity Index (HEIDI), to quantify the potential of Riparian Ecological Infrastru...

Ants as bioindicators of riparian ecological health in catalonian rivers

In this study, we assess the potential of ants as bioindicators of riparian ecological health in two river types (upland and lowland type) located in the Catalonian region. We proposed to understand to what extent do metrics based on ant responses provide useful information that cannot be presented by traditional biophysical assessments while attempting an approach to creating an ant-based multimetric index (an...

Carbon stock estimation in a Mediterranean riparian forest: a case study combin...

This study aims to estimate the total biomass aboveground and soil carbon stocks in a Mediterranean riparian forest and identify the contribution of the different species and ecosystem compartments to the overall riparian carbon reservoir. We used a combined field and object-based image analysis (OBIA) approach, based on unmanned aerial vehicle (UAV) multispectral imagery, to assess C stock of three dominant ri...

Urban trees facilitate the establishement of non-native forest insects

Cities, due to the presence of ports and airports and the high diversity of trees in streets, parks, and gardens, may play an important role for the introduction of invasive forest pests. We hypothesize that areas of urban forest facilitate the establishment of non-native forest pests. Based on scientific literature and a pan-European database on non-native species feeding on woody plants, we analysed where the...

Effects of a large irrigation reservoir on aquatic and riparian plants: a histo...

Dammed rivers have unnatural stream flows, disrupted sediment dynamics, and rearranged geomorphologic settings. Consequently, fluvial biota experiences disturbed functioning in the novel ecosystems. The case study is the large irrigation reservoir Alqueva in Guadiana River, Southern Iberia. The study area was divided into three zones: upstream and downstream of the dam and reservoir. For each zone, species comp...

Avaliação da composição e estrutura ripária Mediterrânica baseada em SIG e dete...

Riparian forests are responsible for many functions considered essential to the preservation of the ecological condition of fluvial corridors. The aim of this thesis is to characterize the structural and compositional patterns of the riparian vegetation in relation to its ecological quality using remote detection and geographic information systems. Separability analyses allowed to characterize and distinguish t...
