不同林龄樟子松人工林针叶-凋落叶-土壤生态化学计量特征

open access: yesShuitu Baochi Xuebao, 2018
为明确科尔沁沙地引种樟子松人工林生态系统的C、N、P含量及化学计量特征,采用时空互代的方法,在章古台地区选取4种不同林龄(15,25,35,45年)、立地条件基本一致的樟子松人工林作为研究对象,比较针叶-凋落叶-土壤的C、N、P含量及化学计量比的差异,探讨它们随林龄的变化及其相互间的关系。结果表明:(1) C、N、P含量表现为针叶 > 凋落叶 > 土壤,C/N、C/P、N/P表现为凋落叶>针叶>土壤,且在3个库之间都有显著差异;(2)林龄对针叶-凋落叶-土壤的C、N、P及C/N、C/P有显著影响 ...

Between conflict and coexistence: Wildlife in rubber‐dominated landscapes 冲突与共存之间:橡胶林主导景观中的野生动物

open access: yesIntegrative Conservation, Volume 2, Issue 4, Page 240-254, December 2023., 2023
Natural habitat loss forces some wildlife species to increasingly extend their habitats into farmlands. Rubber‐dominated landscapes surrounding protected areas have the potential to facilitate coexistence between people and some wildlife species if young plants are better protected and plantation management is made more wildlife‐friendly.

Glycosylated fibronectin improves first‐trimester prediction of pre‐eclampsia

open access: yesUltrasound in Obstetrics &Gynecology, Volume 62, Issue 4, Page 512-521, October 2023., 2023
ABSTRACT Objective To determine whether maternal serum glycosylated fibronectin (GlyFn) level in the first trimester increases the sensitivity of the Fetal Medicine Foundation (FMF) triple test, which incorporates mean arterial pressure, uterine artery pulsatility index and placental growth factor, when screening for pre‐eclampsia (PE) in an Asian ...

Evaluating pollution‐related damage and restoration success in urban forests with participatory monitoring and digital tools

open access: yesConservation Biology, Volume 37, Issue 5, October 2023., 2023
Abstract Peri‐urban forest monitoring requires indicators of vegetation damage. An example is the sacred fir (Abies religiosa) forests surrounding Mexico City, which have been heavily exposed to tropospheric ozone, a harmful pollutant, for over 4 decades.

Association of alcohol consumption with all‐cause mortality, new‐onset stroke, and coronary heart disease in patients with abnormal glucose metabolism—Findings from a 10‐year follow‐up of the REACTION study 糖代谢异常患者饮酒与全因死亡率、新发卒中以及冠心病的关系——来自REACTION研究10年随访的发现

open access: yesJournal of Diabetes, Volume 15, Issue 4, Page 289-298, April 2023., 2023
Highlights This long‐term longitudinal study demonstrates the association between alcohol consumption and health outcomes in patients with abnormal glucose metabolism including type 2 diabetes mellitus and prediabetes. Occasional drinking (less than once a week) reduces the risk of all‐cause mortality, while heavy alcohol consumption (≥30 g/day for men

Cilostazol treatment for preventing adverse cardiovascular events in patients with type 2 diabetes and coronary atherosclerosis: Long‐term follow‐up of the ESCAPE study 西洛他唑治疗预防2型糖尿病合并冠状动脉粥样硬化患者不良心血管事件:ESCAPE研究的长期随访

open access: yesJournal of Diabetes, Volume 14, Issue 8, Page 524-531, August 2022., 2022
Highlights In this ESCAPE‐extension study, cilostazol treatment reduced the incidence of adverse cardiovascular events in patients with type 2 diabetes when compared with aspirin for a 5.2‐year median follow‐up. During the follow‐up period, no adverse events were noted in the cilostazol group that exceeded those in the aspirin group.

Women's invisible work in disaster contexts: gender norms in speech on women's work after a forest fire in Sweden

open access: yesDisasters, Volume 46, Issue 1, Page 141-161, January 2022., 2022
The aim of this study is to investigate what women do in disaster situations and how both men and women perceive and discuss the work of women. These patterns were evidenced in the stories that were told following the largest forest fire in the modern history of Sweden in July 2014.

A spatially explicit empirical model of structural development processes in natural forests based on climate and topography

open access: yesConservation Biology, Volume 34, Issue 1, Page 194-206, February 2020., 2020
Abstract Stand structure develops with stand age. Old‐growth forests with well‐developed stand structure support many species. However, development rates of stand structure likely vary with climate and topography. We modeled structural development of 4 key stand variables and a composite old‐growth index as functions of climatic and topographic ...
