Objetivou-se avaliar o efeito da aplicação de calcário dolomítico e de diferentes sistemas de pastoreio, na taxa de utilização da pastagem e no número de dias de pastoreio. Assim, constituíram-se 4 tratamentos: P1UC- sem aplicação de calcário dolomítico (U) e pastoreio contínuo (PC- 7 ovelhas/ha); P2UD- U e pastoreio diferido (PD- 16 ovelhas/ha); P3TD- aplicação de calcário dolomítico (T) e PD; P4TC- T e PC. A ...
The aim this study was to evaluate the effect of dolomitic limestone application (uncorrected, U and corrected, C) and two sheep grazing systems (continuous, CG and deferred, DG) in preferred grazing areas, in natural pastures. The stocking rate was of 7 sheep/ha in CG and 16 sheep/ha in DG. In 4 plots of 1ha each, four treatments were constituted: T1 (UCG); T2 (UDG); T3 (CDG); and T4 (CCG). The study was carri...
O Montado/Dehesa é um ecossistema agro-silvo-pastoril característico da região sudeste da Península Ibérica. A gestão das pastagens neste ecossistema é complexa, devido às interações entre estas e o solo, as árvores, os animais em pastoreio e o clima. As preferências alimentares dos ovinos em pastoreio podem ser influenciadas por fatores como a altitude das parcelas, o encabeçamento animal, a disponibilidade de...
Wildfire behaviour depends on complex interactions between fuels, topography, and weather over a wide range of scales, being important for fire research and management applications. To allow for significant progress towards better fire management, the operational and research communities require detailed open data on observed wildfire behaviour. Here, we present the Portuguese Large Wildfire Spread database (PT...
Wild birds may be involved in the transmission of agents of infectious diseases, including zoonoses, a circumstance which raises a number of public and animal health issues. Migratory bird species play a significant role in the introduction of tick-borne pathogens to new geographic areas, contributing to the dissemination of various etiological agents. This preliminary study aimed to assess the occurrence of fo...
(Introdução) As florestas em Portugal ocupam uma área aproximada de 3 224 200 ha, apresentando como espécies predominantes o sobreiro, o pinheiro e o eucalipto (ICNF, 2021). Os pinheiros ocupam cerca de 28 % desta área e geram diversos resíduos, entre os quais as agulhas, que se não forem retiradas das florestas podem agravar o problema dos incêndios florestais (Omvesh et al., 2023). A energia proveniente de re...
Within the discipline of respiratory medicine, there is a growing recognition of the relevance of breathing pattern disorders. Breathing pattern disorder, or dysfunctional breathing, is commonly characterized by an abnormal breathing pattern resulting in respiratory and non-respiratory symptoms, which may occur secondary to diseases or in its absence. The underlying mechanisms can be physiological (e.g. lung di...
We show in experiments that a long, underdense, relativistic proton bunch propagating in plasma undergoes the oblique instability, which we observe as filamentation. We determine a threshold value for the ratio between the bunch transverse size and plasma skin depth for the instability to occur. At the threshold, the outcome of the experiment alternates between filamentation and self-modulation instability (evi...
Objectives: This study aimed to compare the anthropometry and body composition of vegetarian and omnivorous adults living in Portugal, while exploring nutritional and health parameters underlying observed differences. Methods: 425 omnivorous (OMNI), lacto-ovo-vegetarian (LOV), or vegan (VEG) healthy adults were recruited. Anthropometry was measured, and bioelectrical impedance analysis was performed. Participan...
Fintar é adquirível e aperfeiçoável através de exercitação específica. Foi objetivo deste estudo verificar se um programa de exercícios específicos propiciaria melhoria de execução técnica qualitativa de 3 fintas básicas do futebol, em escalões de formação. Doze benjamins (B) (10,58±,52 anos; experiência-3,58±1,56 anos) e 16 infantis (I) (11,25±,58 anos; experiência-3,62±1,96 anos), praticaram ao longo de 6 ses...
