New insights into the seasonality of Amazon's evergreen forests
seasonality Amazon evergreen forests
2016/3/2
Sometimes you can't see the forest for the trees. In the Amazon, the opposite is true: without truly seeing the trees, you can't "see" the forest and understand the seasonal patterns of photosynthesis...
Forests nationwide are feeling the heat from increasing drought and climate change, according to a new study by scientists from 14 research institutions.
"Over the last two decades, warming temperatu...
Wildlife win when cash takes edge off “park vs.people” conservation conflict
Wildlife cash takes edge off park vs.people
2016/2/22
Conserving wildlife habitat sounds noble, but when it comes down to work or sacrifice, cold hard cash – a decent amount of it – goes a long way.
Researchers at Michigan State University and their col...

A new study assessing the influence of species diversity of canopy trees on the amount of ozone precursors a forest emits suggests that atmospheric chemistry models in use now may underestimate the im...
绘图估算全球树木约为3.04万亿棵
绘图 全球树木 3.04万亿棵
2015/9/6
一组包括中国、美国等科学家在内的团队日前进行了一项生态学研究，对除南极洲外的全球树木密度分析显示，地球上树木数量略高于3万亿。该项研究突破了以往遥感技术只能估算出世界森林面积的缺憾，将有助于了解地球的系统动力学以及促进环境管理工作。迄今为止，政策制定者和科学家们都是依靠卫星图像来做出对于世界森林面积的估算的。但是这种遥感技术不能明确给出树木的数目、密度抑或是木材储量，而这几组数据对了解生物过程和生...

欧盟在森林高附加值技术开发上取得重要进展
欧盟 森林 技术开发
2014/11/21
森林工业是欧盟经济的重要组成部分。森林不仅是纸浆与造纸和木材加工工业的重要原料来源，而且一系列重要化合物和珍贵活性物质的重要来源地，是人类共同的资源宝库。然而迄今为止，森林的潜在价值远未得到完全开发，甚至被作为废弃物而丢弃浪费。比如，现如今的通用纸浆加工技术，只有不到50%的原料生物质，被转化为纸浆用于造纸，其余超过一半的原料生物质则成为低价值的副产品，造成资源极大浪费。

2014年8月3日报道 外媒称，有生态环境保护者称，穿山甲因肉味鲜美而频频现身亚洲各国聚会餐桌，致使该物种即将不复存在。2014年7月28日报道称，据信，过去十年间偷猎者从野外抓走的穿山甲超过100万只。
Protected areas failing vulnerable species, researchers say（图）
hreatened species threatened flora and fauna

Future national park expansion should focus on land that is home to threatened species, rather than on land that is cheap to protect, researchers say.
Antarctica’s ice-free areas – home to most of the continent’s biodiversity – need better protection from human impact, says a group of Australian environmental scientists.
A Papua New Guinea bat species thought to be extinct has been rediscovered by a team of University of Queensland researchers.
