Exploring the Pleistocene-Holocene Boundary
in the Americas: From Molecules to Continents

Mark your calendar for the
American Quaternary Association Biennial Meeting
to be held 12-15 August, 2010, at the
University of Wyoming in Laramie, Wyoming.
Additional field trips are scheduled on 12 August and
16-17 August, with the Teachers' Workshop
on 10-11 August.
The meeting is hosted by the American Quaternary
Association and the Roy J. Shlemon Center for
Quaternary Studies at the University of Wyoming.

American Quaternary Association (AMQUA)
AMQUA is a professional organization of North American
scientists devoted to studying all aspects of the Quaternary
Period, the last 2 million years of Earth history.
The Quaternary Period is significant because the Ice Age
environmental changes associated with the growth and decay
of continental glaciers were the backdrop for global changes
in floral and faunal communities, including extinction of
diverse megafauna, and for the evolution of modern humans
and their dispersal throughout the world.

AMQUA Biennial Meeting
2010 Theme: Exploring the Pleistocene-Holocene Boundary
in the Americas: From Molecules to Continents
The 2010 AMQUA Program will focus on the
Pleistocene-Holocene transition in the Americas, exploring
the causes and consequences of the dramatic environmental
changes of that transition.
 Plenary talks will address this period from a variety of
perspectives, and present new results and advances in age
estimation, paleoclimate and paleoenvironmental
reconstruction, ancient and modern DNA studies,
societal patterns, and landscape dynamics.
The meeting program is designed to be of broad interest to
Quaternary scientists, encompassing global climate change,
marine and terrestrial ecosystems, geological and
geochemical processes, and human cultures.
Plenary talks have been solicited from experts in their
respective fields, and focus on exciting and topical
developments in the science.
A dedicated poster session is open to all registered
meeting participants.
Posters on any aspect of Quaternary science are welcome.
AMQUA meetings have a tradition of being large and diverse
enough to be of broad appeal, yet small enough to ensure
high-quality and casual social interactions among participants.

Attendance is open to all and university students
are particularly encouraged to register.
The meeting is interdisciplinary in focus and scientists,
educators, and those interested in a wide variety of disciplines
such as oceanography, limnology, paleoclimatology, glaciology,
ecology, geomorphology, stratigraphy, paleopedology,
paleontology, paleoecology, archaeology and anthropology
are strongly encouraged to attend.

Local Chair: Steve Jackson Jackson at uwyo.edu
Scientific Program Chairs: Rolfe Mandel mandel at ku.edu
and David Meltzer dmeltzer at smu.edu

The scientific program will focus on a variety of issues
related the Pleistocene-Holocene transition in the Americas.
 Some of the specific topics that will be addressed are as follows:

Dating the Pleistocene-Holocene transition, including current
calibration efforts and issues of radiocarbon variation and its effects.
Climate and environmental change at the Pleistocene-Holocene transition.
What was the nature of the transition?
How rapidly did change occur?
Scales and thresholds of change and how these vary.
Causes of climatic and environmental change at the
Pleistocene-Holocene transition.
Role of Milankovitch forcing functions vs. greenhouse gasses.
What triggers abrupt climate change?
What caused the Younger Dryas?
Ancient DNA and the genetic consequences of environmental
change during the Pleistocene-Holocene transition.
Landscape response to climatic change during the
Pleistocene-Holocene transition: glacial, fluvial, eolian,
and lacustrine systems.

Climate of the Past

"Climate of the Past" (CP) is open access, on-line journal of the
European Geosciences Union, affiliated with the Climate division.
This journal is free, and you can download anything you want.
Page charges are very low. CP was launched in June 2005 and
will receive its first impact factor this coming summer.
