Subject: High CO2 levels hamper nitrate incorporation by plants

High CO2 levels hamper nitrate incorporation by plants
Rising levels of atmospheric carbon dioxide that are associated with
global warming can interfere with plants' ability to incorporate certain
forms of nitrogen, dramatically altering the plant life worldwide and
forcing significant changes in agricultural fertilizer use, according to
a plant physiologist at the University of California, Davis.
These findings will be reported by lead author Arnold Bloom and
colleagues in the Feb. 5 issue of the Proceedings of the National
Academy of Sciences.
"It's been known for some time that increased concentrations of carbon
dioxide in the atmosphere initially boost carbon intake and growth in
plants but eventually the accelerated carbon assimilation declines,"
said Bloom, a professor in the UC Davis vegetable crops department. "The
results from our study indicate that carbon dioxide inhibition of
nitrate assimilation contributes to this phenomenon and suggest two
physiological mechanisms that may be responsible."
Atmospheric monitoring since 1800 indicates that carbon dioxide
concentrations have risen by more than 30 percent during the past two
centuries. For many years, scientists believed these rising levels of
carbon dioxide would actually benefit plants because carbon dioxide is
one of the essential ingredients in photosynthesis, the process by which
green plants use sunlight to manufacture the chemical energy they need.
Further study, however, revealed that the accelerated rate of carbon
dioxide assimilation wasn't sustained. In laboratory experiments, plants
initially responded to a doubling of atmospheric carbon dioxide levels
by assimilating 30 percent more carbon. But within a few days or weeks,
this accelerated rate of carbon processing dropped back to just 12
percent greater than normal.
Against that backdrop, Bloom and colleagues have been studying how crop
plants respond to being fertilized with two different forms of nitrogen:
nitrate and ammonium. Nitrogen is an element that is key to producing
proteins and nucleic acids such as DNA in plants. Because it is so
important to plant growth, farmers and gardeners commonly apply
nitrogen-rich fertilizers to their crops.
In this newly published study, the UC Davis researchers discovered that
nitrate fertilizer is not nearly as efficient as ammonium fertilizer
when atmospheric carbon dioxide levels are unusually high. In laboratory
experiments they grew wheat seedlings with either nitrate or ammonium
under varying concentrations of atmospheric carbon dioxide. They
discovered that elevated levels of carbon dioxide inhibited the
processing of nitrate in the wheat leaves in two ways.
First, plants place a higher priority on storing and processing carbon
dioxide than they do nitrogen, so when carbon dioxide levels rose, some
of the chemicals needed to assimilate the nitrate were already tied up
in assimilating carbon dioxide.
Second, to make use of nitrate, the plants have to convert nitrate into
nitrite and then move the nitrite into structures within their cells
called chloroplasts, which are the center for photosynthesis. Bloom's
research indicated that elevated levels of carbon dioxide interfered
with the overall process of photosynthesis by blocking this vital
transfer of nitrite into the chloroplasts.
Furthermore, the researchers found that wheat growth wasn't influenced
by the type of nitrogen available as long as atmospheric carbon dioxide
was at a normal level. However, when atmospheric carbon dioxide rose to
nearly twice the normal level -- a level that is likely to be reached
within the next century -- the leaves of plants receiving ammonium
increased in size by nearly 49 percent, while plants receiving nitrate
increased by only 24 percent. In short, the plants receiving ammonium
responded much more to the increased carbon dioxide than did the plants
receiving nitrate.
Additionally, the protein content of the wheat plants receiving ammonium
increased 73 percent under elevated carbon dioxide compared to only 32
percent for the wheat plants receiving nitrate. These data suggest that
rising atmospheric carbon dioxide levels might diminish the nutritional
quality of grain receiving nitrate fertilizer.
"We expect that the data from this study will have real-world
implications for crop production," Bloom said. "In well drained soils
generally devoted to wheat production, nitrate is the common form of
nitrogen available in the soil. This study suggests that a shift to
increase ammonium availability might be needed."
This published study focused only on wheat, but the UC Davis researchers
have since repeated the work using tomatoes and have documented similar
results.
Bloom added that the study also suggests that plant and tree species in
natural ecosystems that depend on nitrate conversion into amino acids in
their leaves are likely to be at a competitive disadvantage to those
species that are either able to convert nitrate into amino acids in
their roots or use ammonium as their predominant nitrogen source. This
may result in significant changes in the distribution of plants in the
wild as atmospheric carbon dioxide levels continue to rise, he
suggested.

Subject: credit for undergrad research
Greetings,
I'm trying to gather some information on how primarily undergraduate
institutions assign credit to faculty for guiding undergrad research. For
instance, is research considered part of your load, part of an overload
contract (if so, are the overload hours considered the same as any other
course hour), or do you receive no credit at all? Please reply to me and I
will post a summary if people are interested.
Thanks in advance,

Subject: duplicated tree measurements
I sent this question out a few weeks ago, and several contacted me asking to
post responses to the list. Below is the original message, followed by
responses.

ORIGINAL MESSAGE
Through perhaps a fortuitous lack of communication, tree diameters in 8
permanent natural area monitoring plots were measured twice within a few
weeks. We'd like to compare the errors that occur when two observers
measure the same trees. Approximately 900 trees were measured twice,
ranging among 8 plots, 7 species and a mix of size classes. Two questions
for the list:
1) Analysis. The plots are subjectively placed permanent plots. All trees
were measured in each plot. We'd like to compare differences between
observers by size class (species should not be relevant- all species are
equally easy to measure- no dense lower branches or forking), and by living
and dead trees. What is the appropriate analysis approach?
2) Does anyone have information on a similar study, either published or
unpublished?
Thanks to the list for help
RESPONSES
As you probably know, assuming you have each tree identified (by
location or whatever) you have a paired sample problem -- two
measurements of each individual tree. I would start with a scatter
plot of diameter versus the difference in the two measurements.
Beyond this, you have to decide what characteristics you want to
measure -- if you care about getting each tree's diameter correct,
look at those data, if you care about getting numbers of trees in
different size classes correct, look at those data, etc.
Cheers,
Peter

There was a thread a few weeks ago on the list about error rates. As I
recall, someone said that there were rates that had been developed from
medical tests, or chemistry experiments or something. Sorry I can't be more
specific, but a quick check in the archives might lead to something.
I'm glad I wasn't the person who measured all those trees after they had
already been measured!

This will be a really interesting comparison. I have a lot of
student-collected DBH data, and should probably do this sort of repeat data
collection with them -- but I'd be afraid about what I'd find out! I hope
you'll publish your results, or at least send a note to ECOLOG-L when you
have
the data.
Good luck! -- Linda Fink, Sweet Briar College
if the trees are individually identifiable (i.e., are tagged) then you
can do a paired sample t-test, which tests whether the difference
between measurements on each individual is zero.
Otherwise, you may be able to create a histogram of tree size classes,
and compare the histograms from the two samples using chi-square
contingency tables of numbers in each size class. Since measurement
errors are likely to be small and random, I think it is unlikely this
will result in a detectable difference, unless the groups were
measureing the trees differently.

Hi,
I did something similar for corals, also comparing the results to digitized
traces. One set of measurements was taken by a second observer but because
of some complications I may have stuck to the measurements
I took. I am in the field and can't check.
I was able to use repeat measure statistics. Can you match each measurement
to a particular tree, producing pairs of measurements for
particular trees? If so you can use repeat measures stats. As a first
cut just plot the two measures (with a diagonal to show perfect
correlation).
You may find inferential tests unnecessary if the plot results are clear
enough.

Subject: <No subject given>
my department has been rambling over how to revise our introductory
non-majors bio course for the past year or so.. one of the thing that many
of us have considered is "reversing the order" in which we address the
material, going from the large to the small, thus ecosystems to atoms. the
inherent problem we have run into is that of the 10 or so text books I have
sitting before me, all of them have the same format--- atom to ecosystem.
We could reformat, but it always seems awkward when the students start the
semester on chapter 35 and end in chapter 3
what books are people using for intro non-majors biology, and are there any
texts that go from ecosystem to atoms
thanks in advance.....

Subject: Re: text book
Charles,
I just made a similar request on list last week, and it sounds like a
number of schools are using this approach. Unfortunately, it sounds like
there really isn't a text that really works this way. There was a text by
Levine and Miller (ISBN - 0-669-34077-4) - DC Heath pub., but I haven't
been able to locate it. The publishing house was sold and no longer lists
this book. I did use the first edition of it some time ago and really
liked it. Supposedly a revision is due, but it's been 8 years now.
Perhaps it's time for a new text. I for one am sick to death of receiving
new books that are essentially identical to everyone else's text.
Another approach is to avoid textbooks entirely, and have the students
purchase a small group of "popular" press books. I'm thinking along the
lines of "One Renegade Cell" by RA Weinberg to cover genetics and maybe
cell stuff. Then perhaps "Song of the Dodo" or EO Wilsons "Diversity of
Life" or some such tome for Ecology and Evolution. I'm still mulling this
over - I've got until April to decide on books. Of course, this has to be
supplemented with plenty of handouts, and I'm not sure how the approach
would work in a really large class. I know University of Chicago was
planning to try this. Don't know how it's working though because I left
just prior to their initiating the new scheme.
Hope this helps.
