[ECOLOG-L] Doubts about using GLA program
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! Prof. Dr. J. C.

[ECOLOG-L] looking for courses in marine reserve evaluation
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! -Chiara Zuccarino-Crowe

Riparian gallery forests on the San Pedro are inhabited by a large variety of bird species (1/2 of all North American Bird species stop along the San Pedro as either breeders or migrants), and is also rich in reptile and invertebrate diversity. We also work in the nearby Huachuca Mountains in unique Madrean pine-oak forests. These mountain canyons are world-famous for their bird diversity (including 13 species of hummingbirds) and also feature a variety of reptiles, mammals, and invertebrates. Basic job requirements: 1.

[ECOLOG-L] Job announcement: Ecology field assistant
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 lodg0...@umn.edu. The University of Minnesota is an equal opportunity employer.
[ECOLOG-L] Ph.D. Position in Soil Microbial Ecology
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.
