[ECOLOG-L] Doubts about using GLA program

2011-04-19 Thread Voltolini
Dear listers,

I need some help to use the GLA Program.

There are a few steps to calculate canopy openess using GLA:

1 - Open an existing canopy image or scan in a new one:
DOUBT: May I use a common square digital photo? I am planing to use black 
and white photos saved as monocromatic bitmap. If not possible, what is the 
best program to use with square digital photos?

2 - Register the image so that both the orientation and circular extent of 
the exposure are known.
DOUBT: I am using the mouse and the pointer to draw a circle in each square 
photo; is it correct?

3 - If necessary, edit the configuration settings to reflect the site 
position and orientation, growing-season length, and atmospheric conditions.
DOUBT: When using a square digital photo what to change in the configuration 
settings?

4 - Threshold the image so that the each pixel is accurately classified as 
either a sky (white) or non-sky (black) pixel.
DOUBT: If I am using black and white pictures, it is usefull to use the 
threshold tool? It seems to me that does not change the results in this 
case!


Thanks for any help!

[ECOLOG-L] looking for courses in marine reserve evaluation

2011-04-19 Thread Chiara Zuccarino-Crowe
Hello all,
 
Does anyone know of any short courses or workshops being held about either the 
siting of marine reserves or the ecological/socioeconomic evaluation of 
existing ones?  Unfortunately, it seems that most workshops that were 
previously held on this topic are not being offered in the near future.  I am 
looking to enhance my skills in this area and would ideally like to do so 
before this August.
 
Thank you!

Hi all,

I was wondering if someone on here was familiar with any sort of behavioral
analysis software?  What I'm looking to do is analyze and track behaviors of
braconid and encyrtid wasps.  I'm looking for something that is either free
or cheap.

Thanks a lot.

[ECOLOG-L] Job announcement: Ecology field assistant

2011-04-19 Thread Alexandra Lodge
POSITION ANNOUNCEMENT: Ecology Field Assistants
Forest Ecology Lab, University of Minnesota

Two graduate students are looking for field assistants, roughly from June 1 to 
August 30 (start and 
end dates are flexible). The overall research project examines whether there 
are characteristics of 
northern hardwood forests that make them more or less resistant to invasion by 
nonnative plants 
(e.g., buckthorn, garlic mustard). Sites will be established across Minnesota 
in forests that have 
experienced a range of recent disturbances, including timber harvests and 
invasive plant removal. 
Light levels and soil characteristics will be measured and a survey of all 
native and nonnative plant 
species present at each site will be conducted. This research will be used to 
support management 
guidelines to restore or maintain healthy forests so they can better resist 
invasion. Field assistants 
may have the opportunity to be involved in two different sub-projects, one 
focused on assessing 
whether and how white-tailed deer facilitate invasions by nonnative plants and 
the second on 
assessing how different invasive species removal methods affect the 
environmental conditions that 
regulate invasive plant colonization.

Field work will take place on public lands such as state parks, wildlife 
management areas and 
scientific and natural areas, some of which may be remote. Working conditions 
can be challenging, 
and ticks, poison ivy, and biting insects are common. Working rain gear and 
quality footwear 
(waterproof hiking boots) are essential. It is preferable (but not essential) 
that the field assistant 
has his/her own tent/sleeping bag. Trips to field sites will include day trips 
based out of St. Paul, 
MN, and camping trips throughout the state (3-10 days).

Responsibilities include assisting with identification of plant species and 
collecting and recording 
data in the field. 

DESIRED QUALIFICATIONS: 1) familiarity with plant identification (especially 
knowledge of 
Minnesota flora), 2) willingness to work hard in an outdoor setting, 3) 
enthusiasm and curiosity.

Pay rate is $10.00/hour.

Duration: June through August 2011

TO APPLY: Please email resume and short cover letter as soon as possible to 
Sascha Lodge at

[ECOLOG-L] Ph.D. Position in Soil Microbial Ecology

2011-04-19 Thread Serita Frey
Ph.D. Position in Soil Microbial Ecology beginning Fall 2011

Serita Frey, Department of Natural Resources  the Environment, University 
of New Hampshire, Durham, NH USA

Our lab is focused on understanding the linkages between microbial 
community structure and ecosystem function.  We examine how environmental 
change (climate warming, nitrogen deposition, biodiversity loss, invasive 
species) alters the biodiversity, community composition, and function of 
the soil microbial community and how shifts in the community feedback to 
influence ecosystem-scale nutrient cycling processes.  Currently, we are 
focused on understanding how chronic soil warming and nitrogen deposition 
influence the diversity, evolution, and function of decomposer fungi.  Our 
work is done primarily within the context of several global change 
experiments at the Harvard Forest Long-Term Ecological Research (LTER) 
site in Petersham, MA USA.

The student will have flexibility to explore questions that fall within 
the broad framework outlined above.  The student is expected to have 
strong interests in ecology, soils, microbiology, and biogeochemistry.  
Applicants should be able to work independently, but also cooperatively 
with other members of the lab.  Interest in and experience with high-
throughput sequencing methodologies is desirable.  An MS degree in 
biology, ecology, natural resources, microbiology, or related field is 
preferred, though applicants without an MS degree, but with relevant 
research experience, will be considered.  The position stipend will be 
$24,000 to start with health insurance and a full tuition waiver.

To apply please send the following items in a single PDF file to Serita 
Frey (serita.f...@unh.edu):   letter of interests/experience, CV, 
unofficial transcripts, and the names and contact information for three 
professional references.
