O armário: Fruiting phenology data for 4,462 plant taxa in Portugal (1926-2013)
Heleno, Ruben; Costa, Jose M.; Covelo, Filipe Manuel Ferreira Rodrigues; Santos, Joaquim; Lopes, Pedro; Gouveia, António C; Matos, ArménioSpecies phenology - the timing of key life events - is being altered by ongoing climate changes with yet underappreciated consequences for ecosystem stability. While flowering is generally occurring earlier, we know much less about other key processes such as the time of fruit ripening, largely due to the lack of comprehensive long-term datasets. Here we provide information on the exact date and site where seed...
The disruption of birds' double mutualistic interactions in novel ecosystems
Nereu, Mauro Guilherme Pereira; Silva, Joaquim S; Timóteo, SérgioNon-native trees disrupt ecological processes vital to native plant communities. We studied how forests dominated by Acacia dealbata and Eucalyptus globulus affect the role of birds as dual pollinators and seed dispersers in a region heavily impacted by these two non-native species. We compared bird-plant interactions in the native and in the two non-native forest types. We constructed a multilayer regional net...
Site and landscape scale drivers of bird and insect diversity in Native and nov...
Nereu, Mauro Guilherme Pereira; Silva, Joaquim S; Timóteo, SérgioThe natural forests of southern Europe have been altered over the last decades. One of these changes is the proliferation of invasive woody alien species, resulting in highly altered ecosystems, the so-called “novel ecosystems”. These changes affect biodiversity at both local and landscape scales. Using piecewise structural equation models, we evaluate the effects of local and landscape variables on the diversi...
