From piecing together thousands of years of climate data preserved in ice cores around the world Thompson has learned that periods of extended drought correspond with major world crises--famine disease and war.
The guide has become the core of northern hardwood silviculture particularly in the Great lakes region.
By analysing ice cores from Antarctica along with data from tree rings and lakes in South america Dr Abram and her colleagues were able to extend the history of the westerly winds back over the last millennium.
Slender cores were collected from the trunk of more than 1000 ash trees across six counties in southeast Michigan.
By studying the tree rings on each core and identifying key marker years the team was able to determine the year each tree was killed by emerald ash borers.
For this study the BYU geographer took sample cores from Douglas fir and pinyon pine trees. The thickness of annual growth rings for these species is especially sensitive to water supply.
At its core is a curriculum that integrates classroom nutrition activities with physical activity and gardening.

#Greenland ice cores show industrial record of acid rain, success of US Clean Air Actthe rise
UW researchers began their study of ice cores interested in smog not acid rain. They discovered a link between the two forms of pollution in the geologic record.
How much the nitrate concentrations in ice core records can tell about NOX and the chemistry in the past atmosphere is a longstanding question in the ice-core community said lead author Lei Geng a UW postdoctoral researcher in atmospheric sciences.
Unlike other gases short-lived NOX can't be measured directly from air bubbles trapped in ice cores.
Within a day or two most of the NOX changes into nitrate a water-soluble molecule essential to life that gets deposited in soil and snow.
Ice cores from Greenland and North american lake sediments showed the nitrogen-15 ratio gradually decreasing
and the final signal recorded in the Greenland ice cores is actually not just the nitrogen emission
The ice cores used in the study were collected in 2007 at Summit Station Greenland. Total amounts of nitrate for each year were measured
Acid air can also influence the reactivity of nitrate in snow and thus the preservation of nitrate in ice cores.
Other ice core records might also be affected by acidity in air Alexander said. No effect would be expected for stable gases like carbon dioxide
and preservation of other volatile compounds such as chlorine mercury or organic materials in ice cores.
and collated with other data on GBIF and Encyclopedia of Life right on the day of publication through a specially designed format called Darwin Core Archive.
Brown researchers have compiled a detailed Indonesian climate record of the last 60000 years tracking telltale indicators in sedimentary cores:
To arrive at those conclusions the researchers used sediment cores from Lake Towuti an ancient lake on the island of Sulawesi in central Indonesia.
The ratio of those two isotopes in the sediment cores is an indicator of the relative abundance of grass versus trees.
The cores showed an increase in abundance of grass in the same sediments that showed a decrease in surface runoff.
and Russell recently received funding to take deeper cores. Ultimately Russell hopes his work will help to predict how the region might be influenced by human-forced global warming.
The course covered 11 broad topics and approximately five core concepts per topic. Questions on the midterm and final exams covered specific concepts and topics so by comparing how the two groups fared on those questions the research team could compare

and management and research technician Scott Morris gathered soil cores--from both within and outside of fenced deer exclosures
They found the soil cores from outside of the exclosures contained many more seeds from nonnative species. Deer select forests for their trees
But in recent years sediment cores drilled in the Bering sea and along the Alaskan coast--the now-submerged lowlands of Beringia--found pollens of trees and shrubs.
An infestation of one larva per core will result in about a 1 percent yield loss Gore said.
Typical infestations in the Delta range from 10 to 25 weevils per core in untreated fields resulting in a 10 to 25 percent yield loss.
because their low tensile strength requires steel-core reinforcement. Scientists working with nanoscale materials have thought long there's a better way to move electricity from here to there.
Not only have shown we that this specific technology can save thousands of lives each year we've also demonstrated a technology pipeline that can produce many similar technologies in the future.
what processors and seed companies need to know in order to make improved production decisions. In other words Williams said researchers need to start speaking the same language as the sweet corn industry.
Williams explained that the two variables that affect processor decisions most include recovery (percentage of kernels that can be canned
In his study Williams looked for relationships between processor variables and 17 crop traits (5 plant traits 8 ear traits and 4 yield traits.
A change in the way sweet corn research is done will have an impact on how processors growers
