Background:Variable Retention Harvesting(VRH)is a forest management practice applied to enhance forest growth,improve biodiversity,preserve ecosystem function and provide economic revenue from harvested *** are many different forms and compositions in which VRH is applied in forest *** this study,the impacts of four different VRH treatments on transpiration were evaluated in an 83-year-old red pine(Pinus Pinus resinosa)plantation forest in the Great Lakes region in *** VRH treatments included 55%aggregated crown retention(55A),55%dispersed crown retention(55d),33%aggregated crown retention(33A),33%dispersed crown retention(33d)and unharvested control(CN)*** VRH treatments were implemented in 1-ha plots in the winter of 2014,while sap flow measurements were conducted from 2018 to ***:Study results showed that tree-level transpiration was highest among trees in the 55d treatment,followed by 33d,55A,33A and CN *** found that photosynthetically active radiation(PAR)and vapor pressure deficit(VPd)were major controls or drivers of transpiration in all VRH *** study suggests that dispersed or distributed retention of 55%basal area(55d)is the ideal forest management technique to enhance transpiration and forest ***:This study will help researchers,forest managers and decision-makers to improve their understanding of water cycling in forest ecosystem and adopt the best forest management regimes to enhance forest growth,health and resiliency to climate change.

discrepancies between the responses to skin prick test to food and respiratory antigens in two subtypes of patients with irritable bowel syndrome

World Journal of Gastroenterology 2008年第19期14卷 3044-3048页

AIm:To compare the response to skin prick tests (SPTs) to food antigens (FAs) and inhalant allergens (IAs) in patients with two subtypes of irritable bowel syndrome (IBS) and healthy controls. mETHOdS:We compared the results of SPTs for IAs and FAs in 87 volunteers divided into three groups:diarrhea predominant IBS (d-IBS) GroupⅠ(n = 19), constipation predominant IBS (C-IBS) Group Ⅱ (n = 17), and normal controls Group Ⅲ (n = 51). RESULTS:Of the 285 tests (171 for FAs and 114 for IAs) performed in GroupⅠwe obtained 45 (26.3%) positive responses for FA and 23 (20.1%) for IA. Of the 153 tests for FA in Group Ⅱ, we obtained 66 (20.1%) positive responses, and of the 102 tests for IA, we obtained 20 (19.6%) positive responses. Of the 459 tests for FA performed in Group Ⅲ, we obtained 39 (84%) positive responses, and of the 306 for IA, we obtained 52 (16.9%) positive responses. The numbers of positive responses were not significantly different between the three groups, but in the d-IBS group, the number of SPTFA responses differed significantly from those for the other two groups (P despite the small number of cases studied, the higher reactivity to FAs in GroupⅠcompared to Groups Ⅱ and Ⅲ adds new information, and suggests the presence of a possible alteration in intestinal epithelial function.
