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...
Physical and sport activities in school and community context : what impact on ...
Ribeiro, Jorge Manuel Pereira; Rodrigues, Luís P.; Santos, Luísa S.; Carvalho, Graça SimõesN.º especial que contém os resumos do "2nd IPLeiria International Health Congress : Challenges & Innovation in Health" ; INTRODUCTION: Health promotion interventions usually occur at school, where young people stay longer. However, physical / sport activity can be organized not only at school but also in the community. Thus, it seems important to investigate the impact of physical activities / sports, at schoo...
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...
Contrasts in the basins of attraction of structurally identical iterative root ...
Basto, Mário; Basto, Luís P.; Semiao, Viriato; Calheiros, Francisco L.A numerical comparison is performed between three methods of third order with the same structure, namely BSC, Halley’s and Euler–Chebyshev’s methods. As the behavior of an iterative method applied to a nonlinear equation can be highly sensitive to the starting points, the numerical comparison is carried out, allowing for complex starting points and for complex roots, on the basins of attraction in the complex p...
The Cholinergic System and Inflammation: Common Pathways in Delirium Pathophysi...
Cerejeira, J; Nogueira, V; Luís, P; Vaz-Serra, A; Mukaetova-Ladinska, EBOBJECTIVES: To investigate whether delirium is associated with an unbalanced inflammatory response or a dysfunctional interaction between the cholinergic and immune systems. DESIGN: Cohort observational study. SETTING: General hospital orthopedic ward. PARTICIPANTS: One hundred one individuals aged 60 and older with no previous cognitive impairment undergoing elective arthroplasty. MEASUREMENTS: Incidence o...
Silica-alumina-niobia (SiO2/Al2O3/Nb2O5) matrix obtained by the sol-gel process...
Tarley,César Ricardo T.; Ávila,Thiago C. de; Segatelli,Mariana G.; Lima,Giovana de F.; Peregrino,Gabrielly dos S.; Scheeren,Carla W.In the present work, a new material, SiO2/Al2O3/Nb2O5 (designated as SiAlNb), was evaluated as an adsorbent in a flow injection spectrophotometric method for online preconcentration and determination of trace amounts of Zn2+ ions. The preconcentration method is based on Zn2+ adsorption onto the surface of SiAlNb in alkaline medium (pH 9.0). The elution step is carried out using HNO3 solution, followed by reacti...

Avaliação das fibras colágenas de meniscos frescos e preservados em glicerina: ...
Vilela,Liana M.; Del Carlo,Ricardo J.; Silva,João Carlos P. da; Matta,Sérgio Luís P.Da; Rodrigues,Mauricio Correia D.; Reis,Amanda Maria S.No presente estudo foi avaliado o efeito da glicerina 98% sobre as fibras colágenas, arquitetura tecidual e o tamanho de meniscos mediais de coelhos da raça Nova Zelândia. Os meniscos foram separados em três grupos: (1) Grupo MF com meniscos frescos (grupo controle), (2) Grupo MG com meniscos preservados em glicerina 98% por 30 dias, e (3) Grupo MR com meniscos preservados em glicerina 98% por 30 dias e reidrat...
Estrutura e celularidade de meniscos frescos de coelhos (Oryctolagus cuniculus)...
Vilela,Liana M.; Del Carlo,Ricardo J.; Silva,João Carlos P. da; Da Matta,Sérgio Luís P.; Rodrigues,Mauricio Correia D.; Monteiro,Betânia S.No presente estudo foi avaliada a arquitetura tecidual, a população celular, assim como a integridade e a distribuição dos tipos celulares em meniscos frescos de coelhos e preservados em glicerina 98%. Foram analisados meniscos mediais de coelhos recém abatidos, que foram distribuídos em três grupos: o grupo MF (n=7), composto por meniscos frescos, correspondeu ao grupo controle; o grupo MG (n=7), composto por ...
