Rapid evolution at the edges of a given species habitat may play a larger role in population expansions than previously suspected, according to the results of a new University of Colorado Boulder-led ...
CU Boulder study:Mate choices of barn swallows tied to diverging appearances
CU Boulder study Mate choices barn swallows tied diverging appearances
2016/8/23
If you are a male barn swallow in the United States or the Mediterranean with dark red breast feathers, you’re apt to wow potential mates. But if you have long outer tail feathers in the United States...

Contrary to expectations that spruce beetle infestations increase the severity of wildfires in southwestern Colorado, a new study led by University of Colorado Boulder researchers has found that this ...
Inbreeding not to blame for Colorado’s bighorn sheep population decline,CU-Boulder study finds
Inbreeding not to blame Colorado’s bighorn sheep population decline CU-Boulder
2015/8/4
The health of Colorado’s bighorn sheep population remains as precarious as the steep alpine terrain the animals inhabit, but a new study led by researchers at the University of Colorado Boulder has fo...
CU-Boulder technology could make treatment and reuse of oil and gas wastewater simpler, cheaper
CU-Boulder technology treatment and reuse of oil gas wastewater simpler cheaper
2015/3/4
Oil and gas operations in the United States produce about 21 billion barrels of wastewater per year. The saltiness of the water and the organic contaminants it contains have traditionally made treatme...

If you were a shrew snuffling around a North American forest, you would be 27 times less likely to respond to climate change than if you were a moose grazing nearby.
为验证氮在植物解除重金属毒害中的积极作用和生理机制,本试验对巨桉(Eucalyptus grandis)幼苗在3种重金属(Cd、Cu和Pb)处理下增施氮肥的生长和光合生理效应进行研究。结果表明:Cd2+、Cu2+和Pb2+处理下,巨桉植株的叶绿素含量、光合作用、PSⅡ原初光化学反应量子产率等均显著低于对照植株;而在重金属处理的同时增施氮肥,则能显著促进植株生长,提高叶绿素含量,增强光合作用和PSⅡ...
以骆驼蓬幼苗为材料，采用盆栽试验研究不同浓度（0、50、100、200、400 mg·kg-1）Ni、Cu处理对骆驼蓬叶片光合作用、叶绿素荧光特性及生长状况的影响.结果表明： 随着Ni浓度的增加，骆驼蓬幼苗叶片的光合色素含量、净光合速率（Pn）、气孔导度（Gs）、蒸腾速率（Tr）、PSⅡ最大光化学效率（Fv/Fm）、PSⅡ电子传递量子产率（ΦPSⅡ）、光化学猝灭系数（qP）及各项生长指标均呈显著下...
