Subject: Re: Experimental Design Questions
Dear Arn,
At first it looks like there are no two identical years and therefore 1
years gap will avoids from plots to be good repetitions. However, working
with fire I know the high variability among "identical" plots. Moreover, if
you want to draw some general conclusions, it should be valid in any year,
this means that inter annual variation is part of the "noise" in the system.
If you will not get a significant effect because this noise it means you do
not have any effect! But if you get an effect in spite this noise you really
got it.
If the size of the plots may have an effect use the small one you can do at
Summer and Spring.

Subject: Water level recorders
Dear all,
For our riparian buffer zone project, we must follow shallow
groundwater level. I have been gathering information about different
devices and our situation seems to be problematic. We have heavy
clay soil rich in iron on one hand, and muddy water on the other,
which may affect capacitance-based devices or any apparatus
sensitive to high amounts of suspended solids (clay).
If you know any solution/device that might solve our problem, would
you please contact me directly (email address below).
Sincerely,

Subject: Flux post-doc position in Oregon
POST-DOCTORAL RESEARCH ASSOCIATE POSITION
EDDY COVARIANCE FLUX MEASUREMENTS
IN PONDEROSA PINE ECOSYSTEMS
----------------------------------------------------------------------------
Applications are invited for a postdoctoral research associate position at
the Oregon State University in Corvallis, Oregon. The successful candidate
will work with Mike Unsworth (Atmospheric Sciences) and Beverly Law (Forest
Science) in a research project on the influence of climate, age, and
management on CO2, water and energy exchange in semi-arid ponderosa pine
ecosystems of central Oregon. We seek a person with experience in the
theory and practice of eddy covariance flux measurements to take
responsibility for the flux and microclimate measurements as part of a
multidisciplinary, multi-institutional team working this project.
Our micrometeorological and biological research in an old-growth ponderosa
pine forest began in 1996, making it one of the earliest sites in the
AMERIFLUX program. It has expanded to include similar studies in a
re-establishing young forest and a mid-aged forest a few miles away.
Through a combination of eddy covariance methods, soil and plant chambers,
sap-flow gauges, root observation tubes, soil water measurements and stable
isotope analyses we, and our collaborators, are exploring the interacting
carbon and water cycles at these sites. The observational program is
closely tied to model development, and to projects designed to scale from
site to landscapes and regions. For further details see
www.fsl.orst.edu/metolius/ <http://www.fsl.orst.edu/metolius/>
The position requires a commitment to field work, most intensively between
about April and October, but with some field responsibilities year-round.
For example, the eddy covariance instrumentation, on 47m and 20m towers,
requires regular attention for maintenance and calibration. Most of the
necessary instruments and software to collect and analyze data are already
operational, but there is scope for further development. We seek a person
with a strong background in boundary-layer meteorology who will have
responsibilities for deploying and maintaining micrometeorological and
climatological instruments in the field, analyzing the resulting data, and
interpreting these data with respect to micrometeorological and ecological
theory. Experience in instrumentation, data management and analysis, and
the ability to write programs in S-plus or other high-level data analysis
software is desirable. The position requires a Ph.D. or equivalent
experience.
Collaborators at the site include: Chris Andersen, Renee Brooks and Jillian
Gregg ( US EPA), Rick Meinzer (US Forest Service), Dave Bowling and Jim
Ehleringer (Univ. of Utah), Dennis Baldocchi (U.C. Berkeley), Frank
Kelliher, and James Irvine, Larry Mahrt and Dick Waring (Oregon State Univ.)
The position is available from August 2001. Funding is available for two
years with the expectation of continuation. Salary will depend on
experience, but is expected to be in the range $36,000-$40,000. Your
application, which should include a curriculum vitae, publication list, and
names, addresses and phone numbers of three professional references, should
be sent to: Dr. Mike Unsworth, College of Oceanic and Atmospheric Sciences,
326 Strand Agriculture Hall, Oregon State University, Corvallis Oregon
97331. Phone (541) 737 5428. E-mail unswortm@oce.orst.edu
<mailto:unswortm@oce.orst.edu>
We will begin screening applications on 18 June, but will consider later
applications until the position is filled. OSU is an AA/EO employer.

Subject: Pikes Peak
ECOLOG -
Over the weekend I was reading about Pikes Peak (in Colorado) and saw
reference to what the author referred to as the OLD FREMONT EXPERIMENTAL
FOREST. According to the text, this was an experiment in which trees from
all over the world were planted to see which ones grew the best at this
location. The authors goes on to say that "unfortunately, you will not see
anything unusual at this site as the experiment ended with the only living
trees being the ones that grow naturally on Pikes Peak."
Can anyone provide additional information on this experiment such as when
it was conducted, by what university or agency, and whether anything was
formally published and/or reported from this study?
Thanks,

Subject: Re: Pikes Peak
I don't know anything about the experiment, but it sounds like similar
experiments that the USFS has carried out in a wide range of environments.
am sure you can get more information from the Forest Service. Last summer I
was on the high plains north of Dalhart, Texas -- short grass prairie and a
part of one of the most extensive treeless areas in temperate climates in th
world. Near a site called Thompson's Grove I examined a stand of many hecta
es
in extent of a large number of tree species, most of which are not native to
the SW or the Central U.S., and certainly not to that grassland environment.
Interpretive signs indicated that the stands were a "reforestation"
experiment. The signs were very old, and the "experiment" probably was also
but I found no dates associated with anything there. There were living tree
,
though only those in a picnic area were large. The trees in the picnic grou
d
were all Siberian Elms, a species widely planted in towns and farmsteads in
he
plains.

Subject: GIS & Remote Sensing for Wildlife Managers
The Smithsonian Institution's Conservation & Research Center is hosting an
Introduction to the use of Geographic Information Systems & Remote Sensing
in Conservation and Wildlife Management training course. This is a one-week
course and is offered June 18-22.
Increasingly, Geographic Information Systems (GIS) and Remote Sensing have
become important tools for decision making and the applied management of
natural resources. Many federal agencies and NGO's rely on GIS and satellite
data for their work and are starting to produce their own spatial databases.
However, there are few training opportunities for wildlife managers to learn
the application of GIS in everyday management situations. Our course will
provide hands-on experience for the collection of data, GIS analysis of the
data, and map making.
This short course will provide wildlife managers with a working knowledge
about the application of Geographic Information Systems (GIS) and Remote
Sensing to the monitoring and management of wildlife and forest vegetation.
Exercises in establishing locations with a Global Positioning System (GPS),
data input into a GIS, and spatial analysis techniques for GIS will provide
hands-on and real world experience during the course. Based on examples
about habitat selection in songbirds and white-tailed deer, course
participants will learn how to:
-Collect GIS data in the field using survey techniques and GPS
-Differentially correct GPS data
-Input GPS data into GIS
-Input field data into GIS
-Use GIS for management of large data sets from multiple sources
-Design and perform analysis using GIS data and spatial analysis techniques.
-Integrate data with ancillary data, such as satellite imagery, aerial
photography, and State Agency databases.

I am designing a field experiment to determine the effects of prescribed
burning on several parameters, primarily species composition and abundance
within two ecological communities. I have a series of detailed hypotheses,
but that's the basic issue. I should emphasize the research is not on the
effects of fire, but on prescribed burning, as a management technique. As in
any field experiment, there are logistical considerations, and applying fire
has it's own unique set. If anyone would like elaboration, I would be happy
to provide that, but to keep this brief, I won't here. Here are my
questions:
1. For logistical reasons, I believe we can probably burn 10 experimental
units in a given period. With 10 controls, that give me an N=10. Call this
set Group 1. I'm concerned, after doing some preliminary analyses, that that
won't give me sufficient statistical power. So, if I were to burn another 10
in the second year (Group 2), could I pool the data from the two years to
look at post fire effects? I understand that the post fire years for Group 1
and Group 2 would be off by one year, and I would be comparing Burn Year +1
for both Groups.
2. My plan is to burn the 10 units in the spring (dormant season). I would
also like to look at growing season burns. Again for logistical reasons, the
burn units will have to be much smaller in the summer than in the spring. I
plan on having units of 1-4 ha in the spring. Summer or growing season units
would probably be 1/4-1/2 ha. Sampling protocols would be the same for both
dormant and growing seaons burns. Can I compare treatment effects even
though the area treated varies between spring and summer burns?
Thanks in advance.

Hi Michael.
You may not be able to assume that a burn in year n is the equivalent of a
burn in year n+1. Conditions at the time might give a very different burn
intensity, with different results. You can't even guarantee that you can
burnt at all the next year.
Another, more confounding factor, is yearly variation from drought,
temperature regimes etc. First year regrowth in one year may be totally
different to first year regrowth in another. In my own research, for
example, storage carbohydrate levels (read energy reserves for growth) in
grasses and herbs were much higher in the first year due to drought.
As another example, flowering of grasses one year was heavy in burnt plots,
but not unburnt. The next year it was heavy in both the burnt and unburnt.
You can see the potential for conflicting results. Compared to the
controls, burning in one year could show a stimulating effect on next
season's flowering. Burning in a second year could show little comparative
effect on next season's flowering, purely because it was a good year for
unburnt to also flower.
