Background： Climate change is likely to cause significant modifications in forests. Rising to this challenge may require adaptation of forest management, and therefore should trigger proactive measures by forest managers, but it is unclear to what extent this is already happening. Methods： The survey carried out in this research assesses how forest stakeholders in Belgium perceive the role of their forest management in the context of climate change and the impediments that limit their ability to prepare and respond to these changes. Results： Respondents indicated strong awareness of the changing climate, with more than two-thirds （71%） expressing concern about the impacts of climate change on their forests. However, less than one-third of the respondents （32 %） reported modifying their management practices motivated by climate change. Among the major constraints limiting their climate red,ted ~ctions, lack of ic^formation was considered the most important for managers of both public and private forests. Conclusions： Knowledge transfer is an essential condition for research to lead to innovation. Improving the communication and demonstration of possible solutions for climate change adaptation is therefore likely to be the most effective strategy for increasing their adoption.

Glyphosate Exposure Associated with Human Neurodegenerative Disorders: A Scoping Review

Journal of Behavioral and Brain Science 2024年第7期14卷 187-209页

作者： Hannah Hutchins David M. Compton kris Dougherty Behavioral Neuroscience Program Palm Beach Atlantic University West Palm Beach Florida USA Department of Biology Palm Beach Atlantic University West Palm Beach Florida USA

Chemically engineered agricultural products such as pesticides, insecticides, and herbicides, although used considerably for both industrialized and personal agricultural use, have recently been associated with a number of serious human health disorders. This rapid literature review aims to accumulate and analyze research from the last ten years, focusing specifically on the effects of exposure to glyphosate-based herbicide products such as Roundup as associated with the formation of various neurological disorders. Specifically, this review focuses on laboratory research using animal models or human cell cultures as well as human population-based epidemiological studies. It associates exposure to glyphosate or glyphosate-based products with the formation or exacerbation of neurological disorders such as Parkinson’s disease, Alzheimer’s disease, seizures, and autism spectrum disorder. In addition, it examines the correlation between the gut-brain axis, exposure to glyphosate, and neurodegeneration.

Comparative Analysis of Statistical Thickness Models for the Determination of the External Specific Surface and the Surface of the Micropores of Materials: The Case of a Clay Concrete Stabilized Using Sugar Cane Molasses

作者： Nice Mfoutou Ngouallat Narcisse Malanda Christ Ariel Ceti Malanda kris Berjovie Maniongui Erman Eloge Nzaba Madila Paul Louzolo-Kimbembe Mechanics Energy and Engineering Laboratory Higher National Polytechnic School Marien Ngouabi University Brazzaville Republic of the Congo National Institute for Research in Engineering Sciences Innovation and Technology (INRSIIT) Brazzaville Republic of the Congo Higher Institute of Architecture Building Planning and Public Works Denis SASSOU N&#8217GUESSO University Kint&#233l&#233 Republic of the Congo Hydrogen Research Institute University of Quebec in Trois Rivieres Quebec Canada Superior Normal School (ENS) Marien Ngouabi University Brazzaville Republic of the Congo

In this work, four empirical models of statistical thickness, namely the models of Harkins and Jura, Hasley, Carbon Black and Jaroniec, were compared in order to determine the textural properties (external surface and surface of micropores) of a clay concrete without molasses and clay concretes stabilized with 8%, 12% and 16% molasses. The results obtained show that Hasley’s model can be used to obtain the external surfaces. However, it does not allow the surface of the micropores to be obtained, and is not suitable for the case of simple clay concrete (without molasses) and for clay concretes stabilized with molasses. The Carbon Black, Jaroniec and Harkins and Jura models can be used for clay concrete and stabilized clay concrete. However, the Carbon Black model is the most relevant for clay concrete and the Harkins and Jura model is for molasses-stabilized clay concrete. These last two models augur well for future research.

本研究的目的是探讨由几个外来竹种（***＇Alata’）组成的竹生物人工林是否对其周围固有的本地植物群系造成负面的影响。这项研究在爱尔兰都柏林的一个六年生的人工竹林中进行。这片竹林和与之特性相同的41个植物篱都经过了检查并得到了其完整物种清单。在42个取样区域共发现有101种物种。利用双向指示种分析法将这些样地分为11组，竹林和植物篱之间没有呈现出明显的区别。在记录树篱（hedges）数据的基础上，绘制了一个物种一面积关系，其关系为公式S=2．366A0．38。通过这个公式计算，竹场周围面积内所包含的物种应该只有37种而不是所发现的39种。多索伦森指数（MultipleS6rensenindices）被用来做每个树篱和竹场之间的两两相交，结果显示平均为0．41±0．10。鉴于结果显示竹场包括比预期更多的物种，并且双向指示种分析法不能明确区分竹和其邻近的之植物篱的基地环境，本研究得出以下结论，在农业环境中外来竹类资源的出现对本地植物区系的生态多样性没有不利的影响。
