HiDaFernPT: Historical data of spore availability for 121 fern and lycopod taxa...
Timóteo, Sérgio; Heleno, Ruben; Covelo, Filipe Manuel Ferreira Rodrigues; Santos, Joaquim; Lopes, Pedro; Carmo Gouveia, António; Matos, ArménioSpecies phenology is being altered by ongoing climate changes with yet underappreciated consequences for ecological processes and ecosystem stability. Contrary to what happens with some key life events of flowering plants, comparatively little information exists about fern and lycophyte phenology and how it is affected by the current climatic changes. In part, this stems from the lack of long-term datasets. Her...
The role of sheltered habitats in biodiversity conservation of species sensitiv...
Baptista, Martim; Carvalho, Rui; Boieiro, Mário; Bartz, M. L. C.; Mendes, Sara; Timóteo, Sérgio; Azevedo-Pereira, Henrique M.V.S.; Alves, JoanaIn the aftermath of 2019’ tropical cyclones Idai and Kenneth, we assessed ground beetle communities of the Gorongosa National Park (GNP) in Mozambique. The influence of habitat shelters, namely the buffering role of closed microhabitat conditions on Alpha diversity and community trait values during a long period of drought, was evaluated across the main habitat types of the park: miombo forests, mixed forests, ...
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...
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...
Structure of a metacommunity of urban bees: Species diversity and spatio-tempor...
Dupont, Yoko L.; Greve, Mette Balslev; Madsen, Henning Bang; Rasmussen, Claus; Timóteo, Sérgio; Olesen, Jens M.As the globe gets more urbanised, the question about how natural biodiversity is structured in cities becomes increasingly pertinent. To contribute to an answer, we studied species richness and spatio-temporal structure of bees in a North European metropolitan area. A gradient of 13 sites in the city of Aarhus, Denmark, was censused from April to September 2016. Forty species, i.e. 29 solitary species (40 % of ...
Friend or foe? Attitudes of rice farmers toward wild animals in West Africa
Chaves, Patrícia; Schaafsma, Marije; Dabo, Djunco; Lomba, Judite; Mané, Fodé Abulai; de Lima, Ricardo; Palmeirim, Jorge; Rocha, Ricardo; Seck, SambuAs the global human population grows and the demand for space and resources increases, human-wildlife interactions and conflicts are expected to rise, particularly in biodiversity-rich tropical agroecosystems where subsistence farmers and wildlife coexist. We investigated farmers' attitudes using the ABC framework, analyzing their affect, behavior, and cognition toward wild animals. Additionally, we explored ho...
