Dietary metabarcoding reveals the simplification of bird–pest interaction netwo...
Silva, Luis P. da; Mata, Vanessa A.; Lopes, Pedro B.; Pinho, Catarina J.; Chaves, Catia; Correia, Edna; Pinto, Joana; Heleno, Ruben H.; Timoteo, SergioAgriculture 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 the...
Limited potential for bird migration to disperse plants to cooler latitudes
González-Varo, Juan P.; Rumeu, Beatriz; Albrecht, Jörg; Arroyo, Juan M.; Bueno, Rafael S.; Burgos, Tamara; Silva, Luís P. da; Escribano-Ávila, GemaClimate change is forcing the redistribution of life on Earth at an unprecedented velocity1,2 . Migratory birds are thought to help plants to track climate change through long-distance seed dispersal3,4 . However, seeds may be consistently dispersed towards cooler or warmer latitudes depending on whether the fruiting period of a plant species coincides with northward or southward migrations. Here we assess the ...
The upsizing of the São Tomé seed dispersal network by introduced animals
Heleno, Ruben H.; Mendes, Filipa; Coelho, Ana P.; Ramos, Jaime A.; M. Palmeirim, Jorge; Rainho, Ana; F. De Lima, RicardoBiological invasions are a major threat to global biodiversity with particularly deleterious consequences on oceanic islands. The introduction of large terrestrial animals – generally absent on islands – can disrupt important ecosystem functions, such as the dispersal of native seeds. However, while the consequences of plant invasions received much attention, the potential of introduced animals to change insula...

Costa, José M.; Ramos, Jaime; Silva, Luís P. da; Timóteo, Sérgio; Andrade, Pedro; Araújo, Pedro M.; Carneiro, Camilo; Correia, Edna; Cortez, José PauloThe consequences of species extinctions in ecological communities may be buffered through the rearrangement (rewiring) of the interactions between the remaining species. The structural and functional consequences of such extinctions can be explored by means of computer simulations that try to predict secondary extinctions and the degradation of ecosystem services. However, to improve the accuracy of these simul...
