Re: [ECOLOG-L] Some ideas for advancing grad education in the face of scarcity
Ryan has many good points. There are certainly roles for faculty, students, and groups of each. My comments are on some low hanging fruit concerning graduate student training. Recognizing the mentioned employment trends, highly motivated/passionate (grad) student groups should identify opportunities to have speakers from varied careers provide not only scientific talks but separate short talks on their careers. Any school with a seminar series could easily increase their students' exposure to varied careers by 1) promoting career diversity among the roster of speakers and 2) asking relevant speakers to add content (5-10 min of their 45 min talk) on career/jobs stuff [or provide a separate mini-talk on their career as X working for Y to the student group]. I know of one large biology department that has acknowledged the cited employment trends and funded an annual roundtable organized by their students. The goal appears to be to empower students to organize a workshop and expose their students to varied career opportunities. The professionals (6-12) were all non-academics and were pressed to talk about their unique career paths. ESA has done similar things.

First, funding for science at a national level is stable or in decline, while the number of labs that need funding to persist is rising sharply. Second, the number of PhDs being granted is vastly outpacing the job market. According to some analyses the percentage of newly granted PhDs that got a job as a tenure track academic in the 1970s was nearly 50%, while that number today is less than 10% http://www.ascb.org/ascbpost/index.php/compass-points/item/285-where-will-a-biology-phd-take-you . In the face of this gloomy picture, action is required and I believe there are some clear steps we can take. In my view, lobbying for more federal money, tweaking how funds are distributed, working toward some supplements to federal funds (e.g., crowdsourceing..like this https://www.kickstarter.com/ and that https://experiment.com/) are good things to fight for. Those are supply side issues...I would like to also propose some practices in graduate training that may be helpful: (a) revive and respect the Master's degree. In my experience, some faculty view a Master's degree as a kind of failure. They tell their very best undergrads to avoid doing a Master's and head straight to the PhD. It is a waste of time they advise, “the Master's degree is functionless”, you can't do anything with that degree, etc. In fact, many, talented, intelligent, undergraduates have no business doing a PhD because they are not suited to the particulars of the academic enterprise. We should do our best to only bring people into PhD programs who are clearly dedicated to every facet of the pursuit (see below). A MS is a good option for many (most, all?) students interesting in career in ecology. A MS serves as a vital testing ground, even for students who feel confident they want to do a Doctorate. A MS gives the student a chance to discover if research is really an endeavor they want to dedicate their life to-- statistical analysis, writing, digging through the literature-- in addition to field work, lab work, or setting up and maintaining an experiment. In my experience ~50% of the undergraduates who think they want to do a PhD, who faculty might say you really should do a PhD, will change their mind during a MS degree. In which case, that student can finish up the MS and head off to a job, instead of leaving a PhD partway through, which is a bad situation for both the student and the mentor. Screening students in this way will help the PhD glut we currently face, resulting in fewer ABDs in the world, fewer PhDs who leave the field, and will allow those involved with training PhD students to focus energy on students who are more likley to stay the course and succeed. (b) filter hard for students coming into our PhD programs. I would recommend a MS and at least one peer-reviewed article submitted, as a general qualification for admittance into a PhD program.

[ECOLOG-L] grinding equipment for plant DNA barcoding project (but large quantities of plant material per sp)
I'm needing to devise a system to grind 28 samples of single species plant material (range of 0.5-26g per sp) for a DNA barcoding project. There are DNA extraction procedures for grinding plant material but they typically work with miniscule amounts of plant material (~0.05 g) and don't seem relevant. I need something that will enable me to process much larger amounts. I also need it to be simple enough to effectively clean and remove extraneous DNA (e.g. bleach or DNA Exitus Plus) between samples. We have a wiley mill but it seems highly likely to have DNA carryover (i.e. DNA contamination). My first thought was liquid nitrogen and a mortar and pestle but this techniques is also typically done on samples that are pretty small (~1g) and am not sure it would work with such large quantities of plant material without me getting a repetitive use injury. I then thought larger quantities of material could be processed with a blender (with water not liquid nitrogen) then freeze dry the homogenized sample. Ideally, I would like the final material fine enough to pass through a 2mm screen but can possibly change this tolerance. Suggestions?

[ECOLOG-L] R code to calculate relative interaction intensity soil feedback
This message contains some R code that some of you may find useful. Previously, I emailed some R code to various people that I knew were doing soil feedback studies. However, I began to realize that other people (e.g. plant competition folks, etc.) might benefit from seeing/using the code to estimate relative interaction intensity (RII) [or something else] with a resampling (bootstrapping) approach. The code is relatively simple so not worthy of a paper but something that is still worth sharing. You can decide. Pasted email- I'm a bit of a newbie with R but after beating my head against a wall for a couple of days made a (minor to R experts) breakthrough that I thought was worth sharing. The R code estimates a soil feedback parameter (RII [relative interaction intensity {Armas et al Ecology 2004}]) and its confidence intervals using a bootstrapping procedure in R. You can change this equation to something else if you wish. You should be able to paste it into R and have it work as a trial as written (you may need to download the boot library 1st if you don't already have it). You can then adapt it as needed by changing the city, x and u names to fit your own dataset. Enjoy! I derived it mostly from here- http://stat.ethz.ch/R-manual/R-patched/library/boot/html/boot.ci.html A statistician reviewed and approved it so it should work as expected. Feel free to share it with others. If you make any useful changes then please let me know.

Re: [ECOLOG-L] Camera Help Needed
Miranda others, Finding a relatively inexpensive solution to a long term photography setup may not be possible. Here are some ideas though. A couple of reasonably priced cameras with housing exist that can be set to do time-lapse pictures where you specify the time the camera is on (e.g. 7-8AM) and the picture interval (e.g. 15min). This would give you 2-4 pics per day. You have a 4MP camera option (PlantCam) for $80 not including memory cards and possible DIY power options http://swampschool.org/new/outdoor-nature-cameras/wetland-plantcam/ (note: they show some wetland field applications on this website) I just purchased one of these but haven't started using it yet but can possibly answer some related questions. For the price it looks like it will work well. The Swampschool mentions the unit will run for ~8wks. Might go longer with lithium batteries... Whether you can ID birds with only 4MP is another question. A higher end 8MP option with motion sensor capabilities and time-lapse capabilities (probably like those described above) is the Wingscapes BirdCam 2.0 (http://www.wingscapes.com/productdetail.aspx?id=WSCA02) ($199). Both products are actually made by Windscapes. I don't know if this will also run for 8wks or not. For DIY power options, you may want to check out this forum (http://www.timescapes.org/phpBB3/viewforum.php?f=12sid=fce0929ad7886c3 9ca92703c42d305c4) on how to power time-lapse camera rigs. You can pretty much modify anything to run off extended power... This website also has information on DIY camera enclosures so you could go that route and use the previously mentioned Canon CHDK route. However, there are a lot of factors to consider when doing these (internal glare off glass, humidity) besides the obvious power and memory issues. Some pricey options (~$2K) can be found in a few different places- https://www.harbortronics.com/Products/TimeLapsePackage/ and http://www.video-monitoring.com/products.htm (I think you can rent these) If you google sciencelookers you'll see that this person has made some really inexpensive longterm time-lapse cameras and enclosures. Not sure if he/she'll loan you or sell you one... Cheers, Kurt ___ Kurt Reinhart, Ecologist USDA-Agric.

[ECOLOG-L] Ques: seed germination of few mixed-grass prairie plants
Hi, Despite having collected seed and done some preliminary germination trials, we are now having some trouble getting seed for a few species to germinate in sufficient quantities for an experiment. Our biggest offender is an exotic forb (Logfia arvensis aka Filago arvensis, Gnaphalium arvense, and Oglifa arvensis). We have limited viable seed for Loar so are trying to use it sparingly. I would appreciate receiving germination recommendations and/or purchasing any extra seed that you may have of Loar. I would also appreciate germination tips for three others that we have ample seed supplies. 1) Pascopyrum smithii (western wheatgrass) 2) Astragulus crassicarpus 3) Astragulus missouriensis For #1-3, we had 10-30% germination in our trial (Petri plate and filter paper) but are having lower success now in pots and trays.

Re: [ECOLOG-L] Are ecologists the problem?-- can cows get a break
It seems that the green movement has chosen beef as their poster child for all that is wrong with agriculture. I agree that overconsumption of any one thing, including beef, is likely to have negative effects on health and that livestock produce methane, an important greenhouse gas. Most of the vilification though appears to stem from high profile news stories about livestock production in feedlots. However, I am continually amazed to see cattle and wildlife convert the inedible semi-arid grasslands that surround where I live in Montana into something that I can use (meat and leather) and provide incomes for others in the region. I certainly could not survive by eating native plants from the northern steppe mixed-grass prairie but ruminant livestock can. This makes me think that a piece of the production cycle is likely being overlooked by the critics of livestock production as they selectively choose to portray the industry as one dimensional. Here in Montana (ranking in the top 10 cattle production states), most cattle are supported by grasslands (i.e. rangelands) for a considerable portion of the year. Our extreme winters require that many receive supplementation (hay) in the winter but use rangelands during much of the year. In fact, the production cycle has been set to maximize utilization of the natural rangeland forges/NPP (i.e. late winter/early spring calving) to build the bulk of a cow while they are mostly just maintained over winter. We still have feedlots but they are rare relatively to rangeland fed beef production systems. Although you can cherry pick examples of how livestock grazing degrades regional rangelands (probably mostly from other regions), most producers ( BLM) in the region have adopted grazing management that is sustainable. This region historically had bison, so the grasslands are resistant to grazing. In many respects, the livestock are now functional analogs to bison (see http://www.esajournals.org/doi/abs/10.1890/04-1958). I suspect bison also emit methane. To have a sustainable business and maintain the numerous multi-generational ranches in the region, livestock producers HAD to develop sustainable practices since the days of the open range, overgrazing, and forage exploitation are long gone. This has helped to maintain relatively natural and diverse grasslands throughout the region that probably don't look that different from what they did ~120 years ago when bison grazed the region (but who really knows). This region has found what appears to be a balance between maintaining considerable natural habitat and wildlife while also providing food and fiber that provide incomes and maintain livelihoods to those in rural communities. In most cases, I would say the livestock industry is an important partner in maintaining natural lands and wildlife in this region much more than an antagonist. Most livestock operations here make money by selling cattle that are exported to other states and likely end up on feedlots at the later stages of their production cycle (e.g. 8 months or more prior to slaughter) [I know that uses fossil fuels]. They are moved to feedlots to improve their meat quality which is now part of market expectations. However, much of their body was built off of resources from natural grasslands. I suspect it is inaccurate to assume that most cattle on feedlots have been their for their entire lives eating corn. Someone out there probably has an actual statistic for the % of American beef that have spent at least a portion of their lives on rangelands. So lets not get too caught up in negative stereotypes and not forget that livestock production systems are diverse and some help to support natural systems that other forms of agriculture/development would likely degrade while still providing food, fiber, and incomes.

[ECOLOG-L] tubes for inserting bags to explore mycorrhizae
As a graduate student, I painstakingly build PCV tubes with carefully drilled holes and glued selective membranes over the openings to allow arbuscular mycorrhizal fungi (AMF) to pass into tubes where plants grew. Now, I would like to do something similar but with a different aim. I would like to insert tubes with selective membranes (or no membranes and instead have sand in membrane sacks) into grasslands to permit sampling of AMF related response variables each year. A tube would allow repeated sampling from a location instead of burying sacks and extracting them--this incorporates spatial variability if sacks are planted into different spots each interval. Ideally, I would like to purchase something that already has openings (holes, slits, etc.) that will permit me to add sand bags, cap, and periodically remove bags. Are any of you doing something similar to measure extraradical hyphae, glomalin, nutrients using resin bags, etc.? I'm sure there is a product related to some sort of filtration for aquaculture, industry, etc. that already has openings and can be modified to function as such a tube. Any tips?

[ECOLOG-L] simulate grazing with mowing treatments
I am looking for ideas on modifying a lawn mower (or something functionally equivalent) to create mowing treatments that will approximate different levels of non-selective herbivory by livestock in semi-arid grasslands. Unfortunately, the chemical treatments to the vegetation that I'm planning prevents utilizing e.g. sheep to naturally graze plots. A mowing solution might require modifying it to attach to an alternate frame to create the ability for setting a wide range of cutting heights to produce different utilization levels (e.g. 45 and 75%) and compensate for variable production among years. Ideally it will also collect/suck up cut material to avoid creating profuse leaf litter so it might need a separate vacuum for sucking up material when cutting at e.g. 25cm off the ground. I suspect safety flaps will also need to be installed to protect the operator from flying debri. We have some really handy shop staff that can build just about anything. So I'm mostly looking for ideas, likely pitfalls to avoid, etc. Any body built something similar or know someone that has?
