dieback

1 According to a study in Maryland of the 1970 Brood X appearance, delayed branch dieback occurred over the following two years in such trees as black gum, purple-leaf plum, photinia, lilac and dogwood.

2 Cultural evolution among groups would tend to exacerbate resource competition and could lead to direct conflict between groups and even global human dieback.

3 If your tree is already starting to turn fall color or, worse yet, starting to show signs of dieback, it’s telling you that it needs water right away.

4 Fortunately, rowan is not part of the ash family and is unaffected by ash dieback.

5 Meanwhile, we are losing ash trees by the million to ash dieback.

6 With dogwoods, once a fungal disease in the system, it will cut the flow of nutrients throughout the tree, causing exactly what you have mentioned — fewer and fewer leaves and then dieback of the leaves.

7 Meanwhile our warmer, wetter winters have accelerated the spread of diseases such as ash dieback, causing significant loss of trees, the charity says.

8 "All but one of the mature trees, which is suffering from ash dieback, within the development boundary will be retained."

9 Jenny Salesa, a Labour party MP, said the national plan to combat kauri dieback was “progressing”.

10 It could get even worse, if warming triggers feedback loops that release even more climate-warming carbon emissions -- such as the melting of Arctic permafrost or the dieback of global forests.

11 Catastrophic dieback would imperil millions of people who rely on the ecosystem for food; 70 percent of the rain that falls in northern Argentina, a South American breadbasket, comes from Amazonian trees.

12 The encouraging news comes from the discovery of a link between reduced susceptibility to ash dieback and lower levels of plant chemicals called iridoid glycosides.

这一令人鼓舞的消息源于这样一个发现：较低的白蜡树枯梢病易感性与较低水平的植物化学物质“环烯醚萜苷类”(iridoid glycosides)之间存在关联。

13 A planting scheme has begun to grow trees that it is hoped will be resistant to ash dieback disease.

14 "Because of ash dieback and the changes in climate - the crisis that we're facing - we have a very finite amount of time to do something about it," she told BBC News.

15 Joseph Hulbert, from WSU’s Forest Health Watch, leads a project gathering data on the red cedar dieback from a network of community scientists.

16 In this new study, Bos and co-authors show that the ferns, which took advantage of the dieback of forests, themselves were subjected to stress from Hg-pollution well beyond the immediate extinction interval.

17 Dieback rate and branching number increased with increasing distance from forest boundaries.

随远离林缘入侵植株枯梢率增高,分枝数增多.

18 Amid rising temperatures and other human pressures, the ecosystem could suffer sudden and irreversible dieback.

19 Projections of Amazon dieback are still much debated, but should countries like Argentina, dependent on the forest for their rainfall, really take the chance?

亚马逊热带雨林盯梢枯死的推测依然争论激烈，但是，像阿根廷这样依赖森林提供降雨的国家真的该抓住这个机遇吗？

20 This would trigger an irreversible process of dieback that could turn the forest into a savannah in a matter of decades.
