Re: [ECOLOG-L] Defining Biodiversity

As a field ecologist who has frequently evaluated and described natural
systems in their entirety and then communicated this information to
non-scientists, I find the term and concept of biodiversity very helpful.
To me, the best definition is the most general definition:  biodiversity
relates to diversity of species (including genetic and age diversity) and of
structure, currently and over time.  A system with high biodiversity tends
to be more productive, stable and resilient.  

A single-age, single-species tree plantation may be productive in economic
terms but it lacks species, genetic and structural diversity so it is not as
ecologically productive, stable or resilient as it could be because of this
lack of biodiversity.

Subject: [ECOLOG-L] Defining Biodiversity

Hi Euan,

I use the broad definition of biodiversity as senctioned by the US
Congressional Biodiversity Act, HR1268 (1990), according to which 

biological diversity means the full range of variety and variability
within and among living organisms and the ecological complexes in which
they occur, and encompasses ecosystem or community diversity, species
diversity, and genetic diversity.

I think biodiversity should continue to have a broad and
all-encompassing meaning, and the communication problem you mention
arises much more from the use of the term in place of more specific
ones, when we refer to specific issues. When communicating with the
public, we should be more specific when speaking about specific issues,
rather than abolishing a term that has a broad meaning, and that should
be reserved for broad themes.

The California Biodiversity Council has a compilation of scientific
definitions of biodiverstiy
(http://biodiversity.ca.gov/Biodiversity/biodiv_def2.html).

 Best whishes,

 Alexandre

[ECOLOG-L] UNEP Policy Series: The role of ecosystems in developing a sustainable Green Economy

2010-12-17 Thread Tingem Munang
The role of ecosystems in developing a sustainable Green Economy 


The second issue of the UNEP Policy Series on Ecosystem Management titled ‘The 
role of ecosystems in developing a sustainable ‘Green Economy’discusses how 
investing in ecosystems can bring about benefits at local as well as at global 
level e.g. in helping communities adapt to climate change (ecosystem based 
adaptation), while at the same time enhancing people's livelihoods. 
Ecosystems and the benefits they provide (e.g. climate regulation, food 
security, freshwater supply, disaster risk reduction) are fundamental to 
supporting people’s livelihoods and other life on Earth. Ecosystems play an 
unequivocal and increasingly important role in both ecosystem-based mitigation 
(carbon sequestration and storage), and ecosystem-based adaptation (i.e. 
nature-based societal adaptation to climate change impacts).
Simply put, Green Economy can be considered synonymous to a ‘sustainable’ 
economy that ensures economic systems conserve natural resources through 
balancing growth and equity. Green Economy balances natural resource values 
with other values, and takes into account the loss in value of ecosystem 
services due to environmental impacts. The requirements for greater valuation 
of ecosystem services fit well with other aspirations of the Green Economy in 
respect of clean, renewable energy, etc.
The key messages in this paper are:

Ecosystems provide extensive benefits for supporting and enriching people’s 
well-being. 
Ecosystem benefits are not adequately valued or accounted for in national 
accounts and decisions. 
Carefully designed response policies for climate change presents an opportunity 
to get the valuation process right by investing in both adaptation and 
mitigation. 
Ecosystem-based adaptation, in particular, can help lead to societal 
transformational change. 
Embracing and capturing economic values of ecosystem services in mainstream 
decision making tools and indicators, for example a national income and growth 
matrix, can help in designing effective policies for sustainable growth and 
societal well- being. 
Investing in a new development model using small-scale fiscal stimulus that 
mobilises the untapped potential of local people is imperative for unleashing a 
low carbon and Green Economy. 
The current economic model driving the world economy is not sustainable. There 
is therefore a need for a new approach to economic development where ecosystems 
are the underpinning foundations.

Re: [ECOLOG-L] Defining Biodiversity

2010-12-17 Thread Martin Meiss
   This thread contains statements of the kind that I think get us in
trouble, if not with the public, then with our scientific rigor.  Axel
Ringe's post begins with what looks like an inclusion from a previous post
with this statement ...one metaphor for biodiversity that I remember was
the phrase web of life.  The imagery contained in that phrase not only
conveys the complexity (species richness)of the organisms making up an
ecosystem, but can also convey the importance of the connections and
dependencies among those organisms.  Pluck one strand, and the whole web may
collapse...
Sure, it's presented as a metaphor, but is it a good one?  First of
all, I have never seen a spider web collapse because on strand was plucked.
Spiders are better engineers than that.  Even if you *sever* a thread, it
usually only causes part of the web to fold up on itself.  Second, does
anyone know of an ecosystem that has collapsed because one species (or some
other entity) was plucked?  Also, what does it mean to say that an
ecosystem has collapsed?  That all it's species are extinct?  That the
habitat that it once occupied is now barren and lifeless?  Extreme
overfishing may cause an extinction or two, and we can say that the fishery
has collapsed, but that collapse is an economic phenomenon, not ecological.
   The chestnut plague in the early twentieth century virtually wiped
out the American chestnut, a dominant species of the eastern forest canopy
in many places.  This caused hardship for humans who used chestnut products,
but I'm not aware of any other species that died off with it.  In fact, we
could say that many other tree species benefited as they moved into gaps
left by the chestnut.  Slaughtering the American bison was, in my opinion, a
terrible crime, but the vultures loved it, at least for a while.
  If we want a vivid metaphor to promote conservation and that will
stick in the public's mind, maybe we should talk about environmental
rape.  This makes the point and at also makes clear that we are talking
about *human values*, not scientific truths.

   Now to Warren Aney's quote: ...A single-age, single-species tree
plantation may be productive in economic
terms but it lacks species, genetic and structural diversity so it is not as
ecologically productive, stable or resilient as it could be because of this
lack of biodiversity
   Yes, of course it lacks species, genetic, and structural diversity,
because that's how it was defined.  This is like saying an all-wood house
lacks bricks.  It's true, but then what?  Further, since it is a plantation,
it's not supposed to be ecologically productive.  It's supposed to produce
whatever its owner's planted it for, presumably wood.  Nor is it supposed to
be stable or resilient; it's supposed to last for thirty years or so and
then be harvested.  Admittedly, during this time its low diversity might
make it vulnerable to disease outbreaks, but this risk may be economically
justified by the ease of managing a uniform stand and then clearcutting it.
   Why am I kvetching about these points?  In the context of a list
serve, I think it is fine to throw out ideas and see what people make of
them.  However, if these issues are not well thought out and carefully
articulated before they are advanced as the basis for public policy, they
will not hold up well in debate.  The proponents may wind up looking bad and
their cause harmed rather than helped.

[ECOLOG-L] Interpreting quadratic terms in regression

2010-12-17 Thread Nabin Baral
Hello Listserv: I am requesting your help in interpreting the results of
quadratic terms in multiple regression.

I've hypothesized a curvilinear relationship (inverted U) between a
dependent and an independent variable. To test this hypothesis, I centered
the independent variable, squared it and entered it along with the linear
term in the regression model. I got different results with independent
variables and I have tried to summarize them in the following questions:

1. Is it necessary to have a positive linear term and a negative quadratic
(squared term) to support the curvilinear relationship?

2. Is it necessary to have a significant linear term too? How you interpret
the result when both the linear and quadratic terms are significant compared
to when the quadratic term is significant while the linear term is not?

3. How do you interpret when both the linear and quadratic terms have
negative beta coefficients?

I would greatly appreciate your time and help.

Thanking you.

Re: [ECOLOG-L] Interpreting quadratic terms in regression

2010-12-17 Thread William Silvert
Although it seems heretical to many ecologists who like to play with 
statistics, it sometimes happens that curvilinear relationships can have 
functional causes that are fundamentally described by mathematical 
relationships. For example, although you can describe a growth curve by a 
parabola, an exponential curve not only gives a better fit but actually 
describes what is happening.


There is virtually no biological process that is fundamentally described by 
a polynomial. Exponentials, yes. Hyperbolic tangents, yes. But quadratics?


Statistical fittings, especially when using biologically meaningless 
functions like polynomials, are merely descriptive and offer lttle insight 
into biological processes. If one can develop even a simple biological model 
of the processes involved, that may suggest functional forms that offer true 
insight and understanding.

[ECOLOG-L] Ecosystem Services: Pricing to Peddle?

2010-12-17 Thread Czech, Brian
With the recent postings on biodiversity, biowealth, ecosystem services, 
etc., I thought it appropriate to relay the recent Daly News:





Ecosystem Services: Pricing to Peddle?
by Brian Czech

On November 15, five nations issued a complaint about a UN initiative called 
the “Global Green New 
Dealhttp://www.unep.org/greeneconomy/GlobalGreenNewDeal/tabid/1371/Default.aspx.”
  These nations claim that “nature is seen [by the UN] as ‘capital’ for 
producing tradable environmental goods and services.”  They express their 
concern about the “privatization and the mercantilization of nature through the 
development of markets for environmental services.”   They also declare their 
“condemnation of unsustainable models of economic growth.”



For the purposes of this week’s Daly News, it matters little who these nations 
arehttp://climateandcapitalism.com/?p=3443, nor does it matter if their 
interpretation of the Green New Deal is completely accurate.  What does matter 
is that their complaint ripens our attention to a widespread and growing 
controversy about the implications of valuing ecosystem services.



The good news from the Green New Deal is that ecological microeconomics (such 
as valuing ecosystem services) has risen from the recesses of academia into the 
realm of international diplomacy.  The bad news is that ecological 
macroeconomics (such as limits to growth) apparently has not.  Let’s take a 
look at the implications.



The primary distinction of ecological economics, in contrast with conventional 
or “neoclassical” economics, is that ecological economists recognize limits to 
growth and a fundamental trade-off between economic growth and environmental 
protection.  The economic pie can only get so big even if all its pieces are 
correctly priced, including ecosystem services.  Because the economic pie can 
only get so big, society must also pay greater attention to fairly distributing 
the pieces.  In order to protect the environment, and to help allocate 
resources in the fairest manner, it helps to recognize the economic value of 
ecosystem services.  That’s what ecological microeconomics is all about; 
estimating the value of natural capital and ecosystem services.



In mainstream economic circles, on the other hand, limits to growth are seen as 
nonexistent or too far off to worry about.  That leads to a nonchalant attitude 
about fairness; just grow the economy because a “rising tide lifts all boats.”  
Traditional economists don’t mind valuing ecosystem services, however.  As long 
as the prices are right, and markets are established, ecosystem services can be 
allocated efficiently, just like steel and milk into guns and butter.



The valuation of ecosystem services provides some common ground for 
neoclassical and ecological economics.  That should be a good thing.  However, 
common ground can be a minefield, too.  Many a well-meaning bureaucrat and 
diplomat are stumbling toward the landmines.



Perhaps the two most common concerns about valuing ecosystem services are:  1)  
Many ecosystem services are beyond the ability of humans to estimate the value 
of, much less to “price” for the market.  “Value of the ozone layer?  
Priceless.”  2)  The valuing of ecosystem services begs a market, then 
monetization of the services such that they are viewed as commodities to be 
traded like hogs or hoola hoops.  For many cultures this offends the senses of 
dignity and harmony with the natural world.  “Would you take 40,000 hogs for 
the climate regulation provided by that forest over there?”



But my concern is with another problem; namely, our inattention to where the 
money comes from to pay for services such as water filtration, carbon 
sequestration, pollination, etc.  There seems to be an attitude that, if we 
just throw enough money at a problem, we’ll solve it.  And that is precisely 
the attitude that creeps in when ecological microeconomics is not complemented 
with a healthy dose of ecological macroeconomics.  Markets convey the idea that 
you can have as much as you want as long as you pay the right price; ecological 
macroeconomics says the total is limited and the right market price should 
simply ration the limited total. And if the total is not limited then it is 
hard for the price to be “right”.



We especially need more awareness of the trophic origins of 
moneyhttp://steadystate.org/wp-content/uploads/2009/12/CASSE_Brief_TrophicStructureOfTheEconomy.pdf.
  Money doesn’t grow on trees, but it does come from the ground in a very real 
sense.  The amount of money available for the purchasing of guns, butter, hogs 
or carbon sequestration originates from the agricultural and extractive surplus 
that frees the hands for the division of labor.



In other words, it is not the ozone layer that “generates” money for throwing 
at its priceless service.  Nor does the North Pole “generate” the money for 
ecotourists to witness it.  What

2010-12-17 Thread Wayne Tyson

Ecolog

While most of the comments on Ritchie's thread were useful to me, I'm not 
sure any of them directly answered Euan's question-- . . . if this term 
isn't helpful for conveying the importance of species diversity to the 
public, what term(s) should we use?


As I said, I dunno. But it has (finally) occurred to me that the message 
should be that life IS diverse; it is NOT a fixed number of species, even 
counting the unknown ones --it is a continuum of life that is, as far as we 
know, a continuously-changing, but always related, phenomenal phenomenon. 
Just simply that is more important as a portal to understanding than all the 
cute Nature TV programs put together, none of which, as far as I know, 
have ever advanced this idea. I hope I am wrong about this, and I earnestly 
hope I will be inundated with examples to the contrary. If not, why not 
produce one? If not, why not just keep hammering away at that point or a 
superior or a more creative statement?


Most of all, I am eager to hear more of the discussion Euan had with his 
colleagues, and what conclusion(s) they may have reached.

We’re particularly excited that this group includes researchers well 
established in their professions, and younger scientists early in their 
research.  

We encourage you to visit www.researchambassador.com where we will post 
updates on Fellows’ activities.

The Research Ambassador Program provides appropriate guidance and rewards 
to academic ecosystem scientists to link their research to an existing 
interest, trade, or hobby of a segment of the public in non-academic 
venues to enhance public engagement and understanding, particularly to 
environmentally unaware public audiences in non-academic settings.

[ECOLOG-L] Vancouver Aquarium Marine Science Centre - Filmmaking for Scientists Announcement

2010-12-17 Thread Jeff Morales
Greetings


The Vancouver Aquarium has teamed up with ScienceFilm to provide a week long
immersion course on telling science stories through film. It is ideal for
working researchers, students, NGOs, communications professionals and other
science professionals. Hosted by the Vancouver Aquarium, it's an exciting
opportunity to gain valuable science communication skills and apply them to
research, management, conservation or web-related projects. Please forward
this announcement and attached flier to any colleagues who may be
interested:


*Workshop Announcement:* *Science Filmmaking at **Vancouver Aquarium Marine
Science Centre**, January 2011
*


*Overview: *This 7-day immersion workshop will teach participants to
communicate scientific findings, natural history information, or
conservation messages by creating compelling, professional-quality videos.
Topics will include story selection, planning, writing, camera technique,
voice-overs, technical aspects of video and audio production, basic video
and audio editing, project output, and distribution. These technical
elements will underpin the main focus of the workshop: effective
storytelling through video. The hands-on approach will be emphasized, and
participants will put concepts introduced in lecture into daily practice.
Opportunities will exist for shooting in the field and studio. Collaborative
opportunities may arise between participants and researchers and staff
working at the Vancouver Aquarium. Participants will also critique existing
documentaries, and by the end of the workshop, students will produce a short
film on a topic of their choosing. * *


*Target audience* : This workshop is intended for researchers and
communicators at any academic level (undergraduate, graduate, postdoc,
faculty, staff, or emeritus) as well as professionals (government, NGO,
industry, etc.). Interested individuals from the general public will also be
accepted. No prior film making experience is required. The workshop will run
with a minimum of 10 participants, and a maximum of 20.

* *

*Instructors: *Jeff Morales (National Geographic Film  Television, amp;
VONIGO Films) and Dr. Colin Bates (Bamfield Marine Sciences Centre 
Department of Botany, University of British Columbia).


*Where:* Vancouver Aquarium Marine Science Centre, Vancouver, BC


*When:* Jan 10 - 16, 2011

 *Cost:* CAD $1200. Includes workshop fees, some supplies  equipment, and
lunches.  Registration deadline is January 4, 2011.

For further information and application materials, contact Jeff Morales (

[ECOLOG-L] PhD Studentship in Community Ecology, University of Zurich

PhD Studentship in Community Ecology, University of Zurich
Institute of Evolutionary Biology and Environmental Studies
University of Zürich

Biodiversity faces many threats. Two of particular importance are
reductions in the amount of
suitable habitat and changes in environmental conditions. Predicting
the consequences of these joint
threats to biodiversity requires an understanding of effects across
multiple levels of ecological
organisation: individual, population, community, and ecosystem. Also
required is an understanding
of how effects at one level of organisation create knock-on effects at
other levels of organisation.
For example, how changes in individual behaviour translate into a
change in population dynamics.
Experiments with small laboratory-based aquatic communities provide an
excellent tool with which
to study effects of habitat availability and environmental change
across levels of ecological
organisation. Such communities allow long-term experiments with
carefully constructed
communities, containing few to many species, short to long food
chains, and low to high trophic
diversity. Long-term experiments (many generations of the dominant
organisms) can be carried out
during quite short experiments, and observations can be made across
levels of ecological
organisation. Mathematical models can be used to link observations
across levels of organisation.
The project will give the successful applicant an opportunity to
perform unique experimental
investigations that will advance knowledge about joint effects of
habitat size and environmental
change.

The PhD will be jointly supervised by Prof. Owen Petchey and Dr.
Dennis Hansen, and will be held
in the Institute of Evolutionary Biology and Environmental Studies at
the University of Zürich,
Switzerland. Funding is available for at least three years. Applicants
must have a Masters Level
Degree in Ecology or a closely related subject, and are asked to
provide a CV, including the names
and contact details of three academic referees, and a one page
research proposal based on the
general project description and relevant published literature.
Informal enquiries should be made to
o.petc...@sheffield.ac.uk or dmhan...@stanford.edu. Applications
should be emailed as a single
pdf-file directly to Owen Petchey before January 31st 2011.
