How renewable power sources grow more trees

Posted 27 Sep 2018 / 0

Science “Climate model shows large-scale wind and solar farms in the Sahara increase rain and vegetation” These kinds of positive feedback loops are exciting. Generally, we are really good at creating deleterious positive feedback loops: changes that further exacerbate our environmental dilemmas. But as this modeling article demonstrates, careful re-engineering of our environment can create Read More

Are corals riding ocean currents to exert climate change dominance over macroalgae?

Posted 06 Sep 2018 / 0

Proceedings of the National Academy of Sciences “Ocean currents and herbivory drive macroalgae-to-coral community shift under climate warming” What’s really interesting in this study is the interaction it discovered: climate change may change competitive dynamics, but it does so in the presence of other factors which also must be modeled in order to predict future competive Read More

Lev Ginzburg Fest: celebration of a “retirement”

Posted 17 Dec 2015 / 0

“Lev Ginzburg has retired”. For anyone who knows Lev, this combination of words does not make a whole lot of sense. Is it possible that such a lively and active scientist would hang up his yellow pad and pencil in order to put his feet up in some retirement community far away from the world Read More

ECOmotion Studios on Simberloff & Wilson’s island biogeography experiments

Posted 06 Oct 2015 / 0

Here’s another classic ecological experiment depicted by the ECOmotion Studios crew, again for the Ecological Society of America‘s centennial. This one uses some of the same narrative approaches as the other shorts in this series, although this one is set to more of a “song” than the others. Narrating an experiment and its rationale is Read More

Rule number one of cooperative bacterial warfare? Be in the majority.

Posted 25 Aug 2015 / 0

Current Biology “Positively Frequency-Dependent Interference Competition Maintains Diversity and Pervades a Natural Population of Cooperative Microbes” This is another great example of how theory that does not consider space is a poor representation of nature. Here, the diversity of a soil bacterium (Myxococcus xanthus) is shown to be potentially explained by positive frequency-dependent selection, the Read More

Carrying capacity — but not growth rate — varies with habitat quality (at least for moose)

Posted 17 Aug 2015 / 0

Ecosphere “Characterizing demographic parameters across environmental gradients: a case study with Ontario moose (Alces alces)” What I find interesting about this study — besides its unprecedented investigation of something that would seem pretty critical to basic conservation efforts — is what was and was not intuitive in its findings. Moose have higher carrying capacities where Read More

Evolution beyond adaptation: a critical step for evolutionary theory

Posted 04 Jul 2015 / 0

The July 2015 issue of Trends in Ecology & Evolution features a really important review article entitled “Selection on stability across ecological scales“. The paper embraces the idea that the stability properties of ecological systems dictate the configuration of extant social groups, interacting species pairs, and overall ecological communities. Lev Ginzburg, my Ph.D. advisor, has Read More

My review of the “Encyclopedia of Theoretical Ecology” published in QRB

Posted 08 Dec 2014 / 0

My review of the Encyclopedia of Theoretical Ecology was just published in the Quarterly Review of Biology. It is a short review so I only give a very brief synopsis of this book, which is pretty remarkable in its scope but also pretty inconsistent in its delivery. I am excited to have this on my Read More

Our review paper on Late Pleistocene Extinction Modeling published in QRB!

Posted 21 May 2014 / 0

I am proud to announce that a paper on which I am co-author, “A review and synthesis of late Pleistocene extinction modeling: Progress delayed by mismatches between ecological realism, interpretation, and methodological transparency“, has been published in the June 2014 issue of The Quarterly Review of Biology. The paper looks at the history of modeling aimed Read More

What happens when a landscape ecologist takes on urban ecology

Posted 29 Jan 2014 / 0

What’s so cool about the work that Eric Sanderson is describing is that it really amounts to doing historical research using an ecological forensics approach. The idea of mapping out “probable areas” of different populations — including humans — using mapped data is pretty smart. It is amazing how humans have transformed Manhattan. Thanks to Read More
