Abstract Early above- and belowground biomass fractionation, root diameter composition allocation of cumulated fine length per total leaf area Populus clones have been measured for a pre-assessment the risk plantation establishment during spring drought conditions. Four × euramericana , one P. nigra maximowiczii clone (cv. Max 3), were planted in sandy mix substrate exposed to normal deficit wa...

BACKGROUND Corticosteroid hormones regulate appraisal and consolidation of information via mineralocorticoid receptors (MRs) and glucocorticoid receptors (GRs) respectively. How activation of these receptors modulates retrieval of fearful information and the subsequent expression of fear is largely unknown. We tested here whether blockade of MRs or GRs during retrieval also affects subsequent e...

in order to study dry matter accumulation in different developmental stages and photoassimilates remobilization in bread wheat genotypes, a field experiment was carried out using a split split plot design based on a randomized complete block design with three replications in torogh agricultural and natural resources research station (mashhad, iran) in 2006-2007 and 2007-2008. main plots were as...

Water consumption by 12 female Przewalski horses was automatically measured in a semireserve for 17 months. Average daily consumption on a yearly basis was between 2.4 and 8.3 liters, but significant individual variation in water consumption and drinking frequency was recorded throughout the observation period. Individual differences were more clearly detectable during periods of hot and dry we...

AMONG the many signs of hypothyroidism, puffiness of the eye-lids is a familiar feature of the facial appearance, but watering of the eyes is not usually reported as a prominent symptom. Recently we have seen five patients who presented to an oculist complaining of watering of the eyes in whom there was found evidence of hypothyroidism and whose symptoms were relieved by the administration of t...

AIMS To determine the efficacy of probing in the initial treatment of epiphora and the symptom free period in adults with blocked nasolacrimal ducts. METHODS The results of probing in 85 eyes with epiphora due to nasolacrimal duct obstruction were studied retrospectively after a mean follow up of 7.4 months (SD 11.6) by a questionnaire and interview survey of patients. RESULTS 35% of the ey...

Climate change induced alterations to rainfall patterns have the potential to affect the regeneration dynamics of plant species, especially in historically everwet tropical rainforest. Differential species response to infrequent rainfall may influence seed germination and seedling establishment in turn affecting species distributions. We tested the role of watering frequency intervals (from dai...
