Endozoochory largely outweighs epizoochory in migrating passerines
Costa, Jose M.; Ramos, Jaime A.; da Silva, Luís P.; Timoteo, Sergio; Araujo, Pedro M.; Felgueiras, Marsial S.; Rosa, Antonio; Matos, ClaudiaFruits and seeds are critical food sources for many European passerines during the autumn migration, which in turn contribute to disperse seeds either internally, i.e. after ingestion (endozoochory), or externally, when seeds adhere to the body surface (epizoochory). Despite the recognized importance of birds as seed dispersers, the vast majority of studies focused on endozoochory while the external transport o...
Assessing the role of body mass and sex on apparent adult survival in polygynou...
Monticelli, David; Araujo, Pedro M.; Hines, James E.; Tenreiro, Paulo Q.; Silva, Luis P.; Ramos, Jaime A.Adult survival, an important fi tness component, is usually 1) lower in lighter individuals due to their reduced ability to survive winter conditions compared to heavier ones, especially in resident species at northern temperate latitudes and 2) lower in females compared with males due to higher reproductive costs incurred by females. In this paper, a capture – mark – recapture dataset of 649 cetti ’ s warblers...
Seed dispersal networks in an urban novel ecosystem
Cruz, Joana Costa; Ramos, J. A.; Silva, Luís P.; Tenreiro, Paulo Q.; Heleno, Ruben HuttelThe conflict resulting from the expansion of human activities into natural habitats affects the structure and functioning of ecosystems. Similarly, the anthropogenic redistribution of many species all over the world affects the composition of biological communities, possibly altering their capacity to sustain key ecological functions, such as seed dispersal. Urban parks are extreme examples of such novel ecosys...
