Aims
The loss of species that engage in close ecological interactions, such as pollination, has been shown to lead to secondary extinctions, ultimately threatening the overall ecosystem stability and functioning. Pollination studies are currently flourishing at all possible levels of interaction organization (i.e., species, guild, group and network), and different methodological protocols aimed to define the resilience of pollination interactions have been proposed. However, the temporal dimension of the resilience of pollination interactions has been often overlooked. In the light of these considerations, we addressed the following questions: does a temporal approach help to reveal critical moments during the flowering season, when pollination interactions are less resilient to perturbations? Do pollination interactions evaluated at species, guild, group and network level show different patterns when assessed through time? 相似文献

Reports regarding gender-related differences in COPD expression have provided conflicting results. In the French Initiatives BPCO real-world cohort, which contained 688 patients (146 women) when data were extracted, women were matched with men (1:3 ratio: n = 107:275) on age (5-year intervals) and FEV1 (5% predicted intervals) and comparisons were performed using univariate logistic regressions. For a given age and level of airflow obstruction, women with COPD had higher BOD scores due to more pronounced dyspnea and lower BMI, suggesting worse prognosis, and were more likely to exhibit anxiety, suggesting the need for specific assessment and care. 相似文献

Recent advances in the knowledge of the structure and function of voluntary muscle and some of its diseases are reviewed on the basis of a recently published international symposium. Among the subjects discussed are: the specific metabolic role of various muscle cell constituents (e.g. sarcosomes, microsomes, sarcoplasmic reticulum); the relaxing factor system and the dual (tonic and phasic) innervation of muscle fibres; observations on the physiology of muscle training; the morphologic differential diagnosis of degenerative skeletal muscle diseases; the value of serum enzyme determinations in the early detection of muscular dystrophy and in the identification of dystrophic carriers; the classification and diagnosis of muscular hypotonias of infancy; the role of inactivity and the trophic control of the nervous system in the development of neural (or denervation) atrophies; factors influencing regeneration of muscle fibres; the significance, as a research tool, of the identification of hereditary primary muscle disease in laboratory animals. 相似文献
