A New Laboratory Scale Olive Oil Extraction Method with Comparative Characteriz...
Ferro, Miguel; Cabrita, Maria João; Herrera, José; Duarte, Maria de FátimaThe establishment of operation protocols for olive oil (OO) extraction at non-industrial scale is crucial for research purposes. Thus, the present study proposes a simple and cost-effective method for OO extraction at the laboratory scale (LS) level. To validate the proposed methodology, industrial OO extraction (IS) was performed in parallel, using the same cultivars ‘Galega vulgar’ (GV), ‘Cobrançosa’ (COB) an...
MAMMALS IN PORTUGAL: A data set of terrestrial, volant, and marine mammal occur...
Grilo, Clara; Mestre, Frederico; Herrera, José; Barrreiro, Sílvia; Silva, Bruno; Costa, Pedro; Salgueiro, Vânia; Mira, António; Milhinhas, CatarinaMammals are threatened worldwide, with ~26% of all species being included in the IUCN threatened categories. This overall pattern is primarily associated with habitat loss or degradation, and human persecution for terrestrial mammals, and pollution, open net fishing, climate change, and prey depletion for marine mammals. Mammals play a key role in maintaining ecosystems functionality and resilience, and therefo...
Cattle-driven forest disturbances impact ensemble composition and activity leve...
Costa, Pedro; Medinas, Denis; Silva, Bruno; Mira, António; Guiomar, Nuno; Sales-Baptista, Elvira; Ferraz-de-Oliveira, Isabel; Simões, Maria PaulaForests can be modified by fine-scale disturbances such as those prompted by cattle grazing, but their impacts on biodiversity are far from being understood. Here, we investigate the response of insectivorous bats to cattle-driven forest disturbances, using a savanna-like Mediterranean agroforestry system, the Portuguese montado, as study system. In doing so, we compared bat ensemble composition and activity le...
A distribution-oriented approach to support landscape connectivity for ecologic...
Herrera, José; Alagador, Diogo; Salgueiro, Pedro; Mira, AntónioManaging landscape connectivity is a widely recognized overarching strategy for conserving biodiversity in human-impacted landscapes. However, planning the conservation and management of landscape connectivity of multiple and ecologically distinct species is still challenging. Here we provide a spatially-explicit framework which identifies and prioritizes connectivity conservation and restoration actions for sp...
Generalities of vertebrate responses to landscape composition and configuration...
Herrera, José; Salgueiro, Pedro A.; Medinas, Denis; Costa, Pedro; Encarnação, Cláudia; Mira, AntónioAim To examine the distributional patterns of vertebrates (including birds, bats, carnivores and lagomorphs) along landscape composition and configuration gradients to better understand the effects of landscape modification on occurrence patterns at both species and community level. Location The region of Alentejo, a forest-dominated area of southern Portugal. Methods The study area was framed using 1647 hexago...
Landscape structure shapes carnivore-mediated seed dispersal kernels
Herrera, José; Teixeira, Isa de Sá; Rodriguéz-Pérez, Javier; Mira, AntónioContext Seed dispersal is recognized as having profound effects on the distribution, dynamics and structure of plant populations and communities. However, knowledge of how landscape structure shapes carnivore-mediated seed dispersal patterns is still scarce, thereby limiting our understanding of large-scale plant population processes. Objectives We aim to determine how the amount and spatial configuration of fo...
Community composition and activity of insectivorous bats in Mediterranean olive...
Herrera, José; Costa, Pedro; Medinas, Denis; Marques, João Tiago; Mira, AntónioOlive (Olea europaea L.) farming is one of the most widespread agricultural practice throughout the Mediterranean basin. Current trends even predict an increase in land area devoted to olive farms as well as the intensification of farming practices. However, knowledge of the effects of olive farming on animal species still remains elusive and conservation and management guidelines for the relevant stakeholders ...
