[ECOLOG-L] Seeking Master's students in evolutionary ecology
The Eco-Evo Lab at California State University, Northridge invites applications from undergraduates interested in pursuing a Master’s of Science in Biology. In particular, we are seeking a M.S. student to work on an NSF-funded project that examines the limits to strong effects of evolution on contemporary ecological interactions. The student will help to perform selection experiments on microcosms of protozoa consumers and their bacterial prey that live inside of carnivorous pitcher plants. We are examining how dispersal and gene flow may alter the evolution of protozoa traits, and how these effects may cascade down to affect bacterial prey diversity and community structure. In general, research in our lab focuses on the interface between ecological and evolutionary processes. We address how rapid evolution affects species interactions, such as competition, predation, and mutualism. We are also interested in how interactions among multiple species in natural communities affect selection on traits and evolutionary trajectories. Research in the lab encompasses a variety of study systems, including (1) microbial communities of protists and bacteria that live inside carnivorous pitcher plants, (2) symbiotic algae associated with coral reef organisms, and (3) invasive plant species in California grasslands. Students are encouraged to develop their own independent research projects. More information is available at http://www.ecoevolab.com The Eco-Evo lab is committed to fostering diversity in STEM. The student will serve as a mentor and role model to undergraduate students that are underrepresented in the field of ecology. CSUN is a Hispanic-Serving Institution and an Asian-American-Pacific Islander-Serving Institution. Women and members of underrepresented groups in ecology are especially encouraged to apply. Northridge is located in the San Fernando Valley in Los Angeles and provides access to many different natural habitats. The location is within a short commute of Santa Monica and Hollywood. The Biology program at CSUN has a reputation of turning out excellent Master’s students who often continue on to top-tier Ph.D. programs. CSUN was recently recognized by *Nature* as one of the top 25 Rising Institutions for Research in North America. Our interactive group combines faculty and students from the Ecology & Evolution program, the Marine Biology program, and the Microbiology program (http://www.csun.edu/science-mathematics/biology). Previous research experience and a passion for answering scientific questions will strengthen candidates’ applications. Interested students should contact Casey terHorst (casey.terho...@csun.edu). In your email, please describe your research interests, any previous research experience, and your career goals. Include a CV or resume, if possible. Formal applications to the department are due on February 15, 2019, but interested students should contact me this Fall semester 2018. --- Casey terHorst Associate Professor Department of Biology California State University, Northridge 18111 Nordhoff Street Northridge, CA 91330-8303 Office Phone: (818) 677-3352 casey.terho...@csun.edu http://www.ecoevolab.com
[ECOLOG-L] Post-doc opportunity
Postdoctoral Research Associate in Microbial Ecology The Eco-Evo Lab at California State University, Northridge is searching for a post-doctoral researcher with skills in microbial ecology and interests in community ecology, evolutionary ecology, or eco-evo feedbacks. The position includes one year of funding, with potential for a second year renewal, from a recent grant from the National Science Foundation. The grant focuses on eco-evolutionary dynamics of protozoa and bacteria that live inside carnivorous pitcher plants. The goal is to examine how dispersal and genetic variation affect the relative effect of rapid evolution and adaptation on ecological processes at the local scale. The post-doc will be based in Casey terHorst’s lab at Cal State Northridge in Los Angeles, CA, but will also work closely with Catalina Cuellar-Gempeler at Humboldt State University and Tom Miller at Florida State University. Candidates should have a Ph.D. or equivalent degree in microbiology, ecology, evolution, or a related field. A successful candidate must be able to work independently conducting experiments in both lab and field settings. As the goal of the project is to examine how protozoan (predator) evolution affects bacteria (prey) communities, experience with aseptic techniques, molecular work, and bioinformatics associated with the study of microbial communities is a plus. A record of publication in this area of research will strengthen an application. The Eco-Evo lab is committed to fostering diversity in STEM.

Re: [ECOLOG-L] Is Nature still a credible journal? Or is this the era of Kardasian science?
I don't think that these metrics should be used as a strict metric of quality, but I don't think they can be dismissed either. The same media that report on pop culture phenomena are also now used to report news from the New York Times, Washington Post, and NPR. Many people now use Twitter, Reddit, Facebook, etc as their primary news source. If a Nature story makes it into somebody's newsfeed and is actually read, I think that's a victory for scientific literacy and public awareness of science. Aside from communication with the general public, articles that were mentioned frequently on Twitter were 11 times more likely to be cited than less frequently mentioned articles (Eysenback 2011). While these metrics should not be used as a proxy for the quality of a paper, they are likely a good proxy for the broader impact of a paper.

Re: [ECOLOG-L] Expanding opportunity and innovation in science
I agree with some of these items and disagree with others, and don't really want to argue those points in this forum. My bigger concern is that if this list is meant to come from a group of scientists, it should include scientific data, rather than opinion and hostility. Are there data that tenure promotes exploitation and laziness? I wouldn't be surprised if there were, but expressing this point as personal experience, rather than a statistical trend, is no different than saying that global warming is a farce because it is cold where I am today. I am less sure that there are data to support spousal hires as deplorable, without merit (surely there is SOME merit, or nobody would do it), and reducing innovation and productivity in science. In my experience, I have seen such hires work out incredibly well for departments and for the field of science, but again, that is just my experience and may or may not reflect a broader trend. Although there are some good points to be made here, expressing them in such a way is unlikely to convince scientifically-minded people (I wish this meant everybody). --- Casey terHorst Assistant Professor Department of Biology California State University, Northridge 18111 Nordhoff Street Northridge, CA 91330-8303 Office Phone: (818) 677-3352 casey.terho...@csun.edu On Tue, Apr 15, 2014 at 7:54 AM, Aaron T.

These researchers could do a lot with such limited resources, as long as we have independence. We could pursue our own funding and even stay in those positions if we don’t feel the need to seek higher titles – just remain productive in that job indefinitely. Those of us who want a larger lab of our own can use the position to create preliminary data and apply for grants to do it – either to “earn” more lab space at the same institution or apply for positions at other institutions. 7) Limit the number of employees that an individual faculty scientists (or “permanent” scientists in federal agencies and national labs) lab can have – limit on grad students, postdocs, and technicians. Possibly only limit trainees (grad students and postdocs). This will allow faculty scientists to actually focus more on science and less on administration of large laboratory empires. Often the lab bosses are disconnected from much of the research going on in the largest labs. This causes an ackward situation whereby the indepdent scientist (postdoc, etc.) who conceived and conducted the research must add the boss to a senior position on the grant or publication artificially, thus making it impossible to distinguish whose ideas they were and who did the work, further exacerbating the difficulty for the employee to get their own independent position and lab. This situation has a severely negative impact on the innovation per dollar of federal funding. 8) End the system of tenure for faculty, it's an out-dated system which severely hampers innovation, reduced career opportunities in science and incentivizes exploitation and laziness. 9) Make

[ECOLOG-L] Graduate Student Positions in Evolutionary Ecology
The terHorst Lab is recruiting 1-2 students to the Masters program at California State University, Northridge for Fall 2013. Research in my lab generally focuses on community ecology and the factors that allow species to coexist. In particular, I am interested in how rapid evolution on contemporary time scales alters the outcome of species interactions and affects coexistence and genetic diversity in communities. My research combines theoretical and experimental approaches that bridge the gap between evolutionary biology and community ecology. More information is available at http://www.msu.edu/~terhors3 I have used several systems to explore these questions, including interactions between invasive and native species in California grasslands, natural microcosm communities inside carnivorous pitcher plants, symbioses between corals and algal symbionts, and communities of epifaunal marine invertebrates. Students are welcome to work in any of these systems, but are also encouraged to develop work in other appropriate field or laboratory systems. Projects that include a theoretical component are encouraged, so programming skills are useful, but are not required. Some examples of potential Masters student projects are: (a) genetic variation in invasive ability and selection on traits during invasion, (b) the effect of gene flow on local adaptation in natural microcosm communities, (c) contemporary evolutionary responses to global change. Northridge is located in the San Fernando Valley in Los Angeles and provides access to many different natural habitats.

Re: [ECOLOG-L] planned contrasts replacing 2-way ANOVA
There should be no problem with using a priori contrasts. No adjustment of the p-value is required, UNLESS the contrasts are non-orthogonal, which is often the case when more than two hypothesis tests. If the contrasts are not orthogonal, some type of adjustment (e.g. Bonferroni) is required, which will lower the power you would otherwise gain with a planned contrast.

Some of these hypotheses can be tested using the usual 2-way ANOVA. That is, the significance or non significance of the two main effects and their interaction is expected to provide sufficient information to draw conclusions regarding these hypotheses. However, another hypothesis focuses on one of the four treatment combinations, and would be best approached by comparing this focal treatment with the other three. However, if I use the 2-way ANOVA, some possible results may be inconclusive, and require further post hoc analyses with a reduced threshold for significance. Since my a-priori hypothesis calls for 3 specific contrasts, it makes statistical sense to me that I can skip the 2-way ANOVA and only perform these 3 contrasts without reducing the significance threshold. The logic behind this is that these 3 planned contrasts replace the 3 component tests of the 2-way ANOVA procedure (2 for the main effects and one for their interaction) that are each always done without any change to the significance threshold. Though I have found support for this approach on online statistics lectures notes, I have never seen it taken in any published study, and I wonder if it is indeed kosher (and if it can be expected to pass reviewers). I would highly appreciate input on this, and especially references to back this approach in case it is valid. Thank you very much, Asaf
Re: [ECOLOG-L] Are ecologists the problem?
There was an interesting article in the August issue of Frontiers in Ecology and the Environment that suggests ecologists have a much larger carbon footprint than the average American, largely because of air travel to meetings, field sites, etc. - Casey terHorst Ecology Evolution Program Department of Biological Science Florida State University 319 Stadium Drive King Life Science Building Tallahassee, FL 32306-4295 terho...@bio.fsu.edu Quoting Kevin McCluney kevin.mcclu...@asu.edu: I recently attended the 2009 annual meeting of the Ecological Society of America (ESA). The theme of this yearÂs meeting was sustainability. There were many great talks on this subject and a few truly pessimistic ones. One speaker proposed that human beings are, by our very nature, destined to consume and reproduce as much as possible, and despite our best efforts, this will lead to our own demise. During the same talk the speaker also asked, Âwho is responsible? He answered his question by saying that we at this conference are just as much a part of the problem as anyone else. Is this true? I know I myself have taken many steps to lower my footprint and many other ecologists have as well. For instance, at last yearÂs ESA meeting in Milwaukee there was an interesting occurrence at local restaurants. The first night of the conference I had a really good veggie burger at one restaurant. I went back later in the week for another. The waitress apologized they were all out. She went on to explain that the manager had heard our conference was coming to town, so bought extra ahead of time, but ran out of those quickly anyway. The manager then went to the local grocery store and bought more. But alas, by the time I returned, they had run out of those as well. Further, when I dine with friends at ESA meetings, I often find that more than half the table orders vegetarian entrees. Why does eating vegetarian matter so much? Modern, industrialized livestock production is one of the more environmentally destructive human endeavors. It contributes roughly one fifth of all our greenhouse gas emissions, more than all cars, and these gases are major contributors to the rapid climate change weÂre experiencing. Livestock production also may, in certain cases, be leading to deforestation and destruction of important ecosystems, as well as to pollution of rivers, lakes, and even oceans. In addition, we all know that basic ecological principles hold that it takes less resources to raise plant based food sources than meat based, since energy is lost as you move up the food chain. Thus we can feed more people and use fewer resources on a plant-based diet. All this caused the chairman of the Intergovernmental Panel on Climate Change recently to proclaim that the best thing a person could do to reduce their impact on climate change was to eat a more plant- based diet. My wife and I havenÂt stopped at eating low on the food chain. WeÂve also joined community supported agriculture, where we buy a share of produce from a local farm. The farmer gets upfront economic security and we get very affordable, local, fresh organic produce. We pay just $18 per week for a large bag of food. At this price we can afford to supplement our diet with additional organic items from the grocery store. WeÂve also taken a variety of other steps, from riding my bike to work, to offsetting car and air travel through renewable energy from an independently certified company, to buying 100% of our electricity from renewable sources through our local utility for as little as $15 per month. While we may not be reaching the small ecological footprint of those in many third world countries, weÂve done our best to come in line with our planetÂs limits while maintaining a decent quality of life. So, are ecologists just as much a part of the problem as everyone else? Are all ecologists the same? What are the variety of lifestyle choices made by ecologists? Not only would the answers to these questions provide a response to the ESA presenter, but I think the answer would be interesting to a wide audience. I propose that ESA conduct a poll of members, asking questions about lifestyle choices and demographics, comparing ours to that of the general public. If we are not different, this would be a bit of a wake-up call. However, if we are different, then perhaps some of our lifestyle choices would be informative to understanding how to achieve a more sustainable society. If there is one thing I learned from a cultural anthropology course I once took, it was that there isnÂt just one right way to live. Human cultures throughout the world are very diverse. But, from the inside of one culture it is often very hard to see other ways to live. Let us not be trapped in our culture, but seek a better understanding of all the ways of living, so that we might find a more sustainable path. -- Kevin E. McCluney
Re: Is biodiversity an ecosystem function?
I've always had difficulty understanding how a static measure (such as biodiversity, or even something like biomass) can be called a function. This is partly just a semantic issue, but largely a real issue as well. Casey -- Casey terHorst Department of Biological Science CON 115 Florida State University Tallahassee, FL 32306 [EMAIL PROTECTED] Quoting Fabrice De Clerck [EMAIL PROTECTED]: I have a quick question for the listserve for which I would be interested in hearing people's opinions, and experiences. The question is: Is biodiversity an ecosystem service? Those of us that work in biodiversity and ecosystem functioning studies typically regard biodiversity at the provider of services and functions. Tilman's biodiversity and productiity, the biodiversity and stability work, biodiversity and pollination (Klein), biodiversity and pest control (Perfecto). Meanwhile in much of the development and economics literature, biodiversity itself is a unique service and function where it is not uncommon to see people state that we will work with farmers to improve the capacity of coffee farms to provide critical ecosystem services such as carbon sequestration, biodiversity and water. Are both correct or is it important to distinguish between biodiversity serving as a function, and biodiversity as the provider of services. All comments are welcome on- or off the listserve.
