Temporal mismatches in flight activity patterns between Pipistrellus kuhlii and...
Herrera, José M.; Carvalho, Ana; Barreiro, Sílvia; Jiménez-Navarro, Gerardo; Melguizo-Ruiz, Nereida; Beja, Pedro; Moreira, Francisco; Vasconcelos, Sasharact 1. Biocontrol services are widely recognized to provide key incentives for bat con- servation. However, we have virtually no information on whether and how dis- ruptions in bat-mediated biocontrol services are driven by mismatches between the temporal activity patterns of insectivorous bats and insect pests. 2. We investigated the temporal relationship between the nightly activity patterns of the common pi...
Disentangling the seasonal effects of agricultural intensification on birds and...
Jiménez-Navarro, Gerardo; Rodríguez-Pérez, Javier; Melguizo-Ruiz, Nereida; Silva, Bruno; Vasconcelos, Sasha; Beja, Pedro; Moreira, FranciscoAssessing the spatio-temporal impact of agricultural intensification on species and communities is key for biodiversity conservation. Here, we investigated the seasonal effects of olive grove intensification at both local (farming practices and grove structural complexity) and landscape scale (land-cover diversity) on birds and bats, at species and community-level. Both groups were surveyed during spring, summe...
Canopy arthropod declines along a gradient of olive farming intensification
Vasconcelos, Sasha; Pina, Sílvia; Herrera, José M; Silva, Bruno; Sousa, Pedro; Porto, Miguel; Melguizo-Ruiz, Nereida; Jiménez-Navarro, GerardoArthropod declines have been linked to agricultural intensification. However, information about the impacts of intensification is still limited for many crops, as is our understanding of the responses of different arthropod taxa and trophic groups, thus hindering the development of effective mitigation measures. We investigated the impacts of olive farming intensification on canopy-dwelling arthropods in the Me...

Structural simplification compromises the potential of common insectivorous bat...
Costa, Ana; Silva, Bruno; Jiménez-Navarro, Gerardo; Barreiro, Silvia; Melguizo-Ruiz, Nereida; Rodríguez-Pérez, Javier; Vasconcelos, Sasha; Beja, PedroCrop production intensification often leads to the structural simplification of production systems. This structural simplification is expected to have strong impacts on biodiversity and the provisioning of ecosystem services, but information about this topic is scarce. For instance, no information exists for Mediterranean olive (Olea europaea) groves, despite olive farming representing a significant share of th...
Effects of olive farm intensification on phytophagous insects and their natural...
Vasconcelos, Sasha; Pina, Silvia; Melguizo-Ruiz, Nereida; Ferreira, Sónia; Sousa, Pedro; Silva, Bruno; Jiménez-Navarro, Gerardo; Jonsson, MattiasOlive farms are progressively expanding in the Mediterranean region, and many have undergone a process of management intensification in recent years. Traditional farming systems involving little or no agrochemical input are rapidly giving way to intensive regimes with very high agrochemical application. However, in spite of this ongoing process of intensification, little is known of its consequences for biodive...
A food web approach reveals the vulnerability of biocontrol services by birds a...
Herrera, José M.; Silva, Bruno; Jiménez-Navarro, Gerardo; Barreiro, Silvia; Melguizo-Ruiz, Nereida; Moreira, Francisco; Vasconcelos, Sasha; Morgado, RuiPest control services provided by naturally occurring species (the so-called biocontrol services) are widely recognized to provide key incentives for biodiversity conservation. This is particularly relevant for vertebrate-mediated biocontrol services as many vertebrate species are of conservation concern, with most of their decline associated to landscape modification for agricultural purposes. Yet, we still la...
Ibagreco2018: I Reunión Ibérica sobre Investigaciones Agroecológicas
Herrera, J.M.; Barreiro, Silvia; Melguizo-Ruiz, Nereida; Ribera, Vanesa; Silva, Bruno; Jiménez-Navarro, Gerardo; Rodríguez-Pérez, JavierEn respuesta al creciente interés entre la comunidad científica en la investigación agroecológica, el pasado año 2017 se creó agreco, el grupo de trabajo sobre Agroecología de la Asociación Española de Ecología Terrestre. Con la creación de agreco, surgía inevitablemente la necesidad de generar un punto de encuentro donde investigadores y actores sociales pudiesen exponer y compartir sus trabajos científicos, a...
