Evidence for climate‐driven synchrony of marine and terrestrial ecosystems in northwest Australia
(Cambridge University PressWiley Periodicals, Inc., 2016-08)
The effects of climate change are difficult to predict for many marine species because little is known of their response to climate variations in the past. However, long‐term chronologies of growth, a variable that integrates ...
Fungal community composition and function after long‐term exposure of northern forests to elevated atmospheric CO 2 and tropospheric O 3
(Blackwell Publishing LtdWiley Periodicals, Inc., 2011-06)
The long‐term effects of rising atmospheric carbon dioxide (CO 2 ) and tropospheric O 3 concentrations on fungal communities in soil are not well understood. Here, we examine fungal community composition and the activities ...
Plant species richness, elevated CO 2 , and atmospheric nitrogen deposition alter soil microbial community composition and function
(Blackwell Publishing Ltd, 2007-05)
We determined soil microbial community composition and function in a field experiment in which plant communities of increasing species richness were exposed to factorial elevated CO 2 and nitrogen (N) deposition treatments. ...
Range dynamics of small mammals along an elevational gradient over an 80-year interval
(Blackwell Publishing Ltd, 2010-11)
One expected response to observed global warming is an upslope shift of species elevational ranges. Here, we document changes in the elevational distributions of the small mammals within the Ruby Mountains in northeastern ...
Cyanobacterial life at low O 2 : community genomics and function reveal metabolic versatility and extremely low diversity in a Great Lakes sinkhole mat
(Blackwell Publishing LtdWiley Periodicals, Inc., 2012-05)
Cyanobacteria are renowned as the mediators of Earth’s oxygenation. However, little is known about the cyanobacterial communities that flourished under the low‐O 2 conditions that characterized most of their evolutionary ...
Diversity regulation at macro‐scales: species richness on oceanic archipelagos
(Wiley Periodicals, Inc.Springer‐Verlag, 2015-05)
AimUnderstanding the mechanisms that generate diversity patterns requires analyses at spatial and temporal scales that are appropriate to the dispersal capacities and ecological requirements of organisms. Oceanic archipelagos ...
Climate‐driven increases in storm frequency simplify kelp forest food webs
(Blackwell Publishing LtdWiley Periodicals, Inc., 2011-08)
Climate models predict a dramatic increase in the annual frequency and severity of extreme weather events during the next century. Here we show that increases in the annual frequency of severe storms lead to a decrease in ...
Elevated carbon dioxide and ozone alter productivity and ecosystem carbon content in northern temperate forests
(SAS Institute Inc.Wiley Periodicals, Inc., 2014-08)
Three young northern temperate forest communities in the north‐central United States were exposed to factorial combinations of elevated carbon dioxide ( CO 2 ) and tropospheric ozone (O 3 ) for 11 years. Here, we report ...
C 3 grasses have higher nutritional quality than C 4 grasses under ambient and elevated atmospheric CO 2
(Blackwell Science Ltd, 2004-09)
Grasses with the C 3 photosynthetic pathway are commonly considered to be more nutritious host plants than C 4 grasses, but the nutritional quality of C 3 grasses is also more greatly impacted by elevated atmospheric CO 2 ...
Anthropogenic N deposition increases soil organic matter accumulation without altering its biochemical composition
(Macmillan Publishing Co, IncWiley Periodicals, Inc., 2017-02)
Accumulating evidence indicates that future rates of atmospheric N deposition have the potential to increase soil C storage by reducing the decay of plant litter and soil organic matter (SOM). Although the microbial mechanism ...
