Dietary metabarcoding reveals the simplification of bird-pest interaction netwo...
da Silva, Luís P.; Mata, Vanessa A; Lopes, Pedro B.; Pinho, Catarina J; Chaves, Catia; Correia, Edna; Pinto, Joana; Heleno, Ruben; Timóteo, SérgioAgriculture is vital for supporting human populations, but its intensification often leads to landscape homogenization and a decline in non-provisioning ecosystem services. Ecological intensification and multifunctional landscapes are suggested as nature-based alternatives to intensive agriculture, using ecological processes like natural pest regulation to maximize food production. Birds are recognized for thei...
Anthropogenic forests simplify seed- but not pollen-dispersal networks
da Silva, Luís P.; Coutinho, António Xavier de Barros e Cunha Pereira; Ramos, Jaime A.; Heleno, RubenNatural native forests are rapidly being replaced by anthropogenic forests often with a strong presence of invasive alien plant species. Eucalypt species are widely planted worldwide, with Eucalyptus globulus plantations being particularly expressive in Portugal. Poor forestry practices often lead to the associated expansion of invasive species, such as Acacia dealbata. However, we still know relatively little ...
Building a Portuguese coalition for biodiversity genomics
Marques, João P.; Alves, Paulo C.; Amorim, Isabel R.; Lopes, Ricardo J.; Moura, Monica; Myers, Eugene; Sim-sim, Manuela; Sousa-Santos, CarlaThe diverse physiography of the Portuguese land and marine territory, spanning from continental Europe to the Atlantic archipelagos, has made it an important repository of biodiversity throughout the Pleistocene glacial cycles, leading to a remarkable diversity of species and ecosystems. This rich biodiversity is under threat from anthropogenic drivers, such as climate change, invasive species, land use changes...

Factors determining the occupancy of nest-boxes by Great Tits (Parus major) in ...
Ceia, Ricardo S.; Lopes, Pedro B.; da Silva, Luís P.Providing nest-boxes as surrogate tree cavities can be of great importance to increase the breeding populations of cavity-nesting birds in managed forests. However, the exact placement of nest-boxes should be taken into consideration to enhance their occupancy according to species-specific preferences. In this study, we investigated which factors can better predict nest-box occupancy by the Great Tit (Parus maj...
Tripartite networks show that keystone species can multitask
Timóteo, Sérgio; Albrecht, Jörg; Rumeu, Beatriz; Norte, Ana C.; Traveset, Anna; Frost, Carol M.; Marchante, Elizabete; López‐Núñez, Francisco A.Keystone species are disproportionately important for ecosystem functioning. While all species engage in multiple interaction types with other species, keystone species importance is often defined based on a single dimension of their Eltonian niche, that is, one type of interaction (e.g. keystone predator). It remains unclear whether the importance of keystone species is unidimensional or if it extends across i...
Tripartite networks show that keystone species can multitask
Timóteo, Sérgio; Albrecht, Jörg; Rumeu, Beatriz; Norte, Ana C.; Traveset, Anna; Frost, Carol M.; Marchante, Elizabete; López-Núñez, Francisco A.1. Keystone species are disproportionately important for ecosystem functioning. While all species engage in multiple interaction types with other species, keystone species importance is often defined based on a single dimension of their Eltonian niche, that is, one type of interaction (e.g. keystone predator). It remains unclear whether the importance of keystone species is unidimensional or if it extends acros...
MAMMALS IN PORTUGAL: A data set of terrestrial, volant, and marine mammal occur...
Grilo, Clara; Afonso, Beatriz C.; Afonso, Filipe; Alexandre, Marta; Aliácar, Sara; Almeida, Ana; Alonso, Ivan Prego; Álvares, Francisco; Alves, PauloMammals 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 mam mals, and pollution, open net fishing, climate change, and prey depletion for marine mammals. Mammals play a key role in maintaining ecosystems func tionality and resilience, and theref...
How to mitigate impacts of wind farms on bats? A review of potential conservati...
Peste, Filipa; Paula, Anabela; da Silva, Luís P.; Bernardino, Joana; Pereira, Pedro; Mascarenhas, Miguel; Costa, Hugo; Vieira, José; Bastos, CarlosWind energy is growingworldwide as a source of power generation. Bat assemblagesmay be negatively affected by wind farms due to the fatality of a significant number of individuals after collidingwith the moving turbines or experiencing barotrauma. The implementation of wind farms should followstandard procedures to prevent such negative impacts: avoid, reduce and offset, in what is known as the mitigation hiera...
Variation in clutch size in relation to nest size in birds
Møller, Anders P.; Adriaensen, Frank; Artemyev, Alexandr; Bańbura, Jerzy; Barba, Emilio; Biard, Clotilde; Blondel, Jacques; Bouslama, ZihadNests are structures built to support and protect eggs and/or offspring from predators, parasites, and adverse weather conditions. Nests are mainly constructed prior to egg laying, meaning that parent birds must make decisions about nest site choice and nest building behavior before the start of egg-laying. Parent birds should be selected to choose nest sites and to build optimally sized nests, yet our current ...
