Why do tropical species appear more sensitive to small environmental changes? New paper out by the Record Lab

Read, Q.D., B. Baiser, J. Grady, P.L. Zarnetske, S. Record, J. Belmaker, and L. Beaudrot. 2018. Tropical bird species have narrower body-size niches. Biology Letters 14 (1), 20170453.
 
Why do species in the tropics appear to be more sensitive to small changes in their environment? This is a question that has puzzled ecologists for generations. Two famous papers from fifty years ago explored this topic. One suggested that species closer to the equator tend to have more specialized diet requirements, and the other observed that environments near the equator have very stable climates, so that species that live there cannot tolerate big swings in temperature. Those ideas led us to predict that bird species outside the tropics would vary more in their body size than birds in the tropics. We tackled that question by compiling bird specimen data from museums worldwide and comparing pairs of sister species. In each pair, one of which lives in the tropics and the other closer to the poles, we compared how much the body size varied. We found that tropical birds indeed have less variable body sizes, supporting our prediction and suggesting that tropical birds will be more susceptible to ongoing human-caused environmental changes. 
This research is supported by a grant from the National Science Foundation. Quentin Read and John Grady are postdoctoral fellows co-mentored by Dr. Record (Bryn Mawr) and Dr. Zarnetske (Michigan State University).

Apply to work with the Record Lab at Harvard Forest in MA this summer

Applications are now open for the 2018 Harvard Forest Summer Research Program, an opportunity for college and university students across the U.S. to participate in 11 weeks (May 21-August 3, 2018) of paid, independent research. Dr. Record has two projects that students can join this summer:

 

Record Lab presents in MD, MI, and CA!

This has been a busy couple months of communicating science for the Record Lab! In September, Kalaina Thorne (BMC ’18) presented her summer research from Harvard Forest at the Young Researcher’s Conference at the University of Maryland College Park. Kalaina received special funding from the Alliance for Diversity in Science and Engineering to attend the conference. Postdoctoral fellow John Grady presented an invited seminar at Michigan State University’s Hanover Seminar Series in the Department of Forestry in October. Dr. Record presented on a panel on data science at all women colleges at the American Statistical Association’s Women in Data Sciences conference in La Jolla, California in October.

Record Lab presents at Ecological Society of America Meeting in Portland, OR

Dr. Sydne Record and postdoc Dr. John Grady presented their work on NSF and NASA funded projects at the Ecological Society of America’s Annual Meeting in Portland, OR last week. A highlight of the meeting for Sydne was catching up over lunch with Tess McCabe (BMC ’16) at a local farmer’s market. Tess is currently a graduate student at Boston University.

Kalaina Thorne (BMC ’18) wraps up summer field research at Harvard Forest

Kalaina Thorne (BMC ’18) joined Dr. Sydne Record and postdoc Dr. John Grady at Harvard Forest this summer to do field research as part of the Harvad Forest Summer Research Experiences for Undergraduates Program. Check out Kalaina’s blog post here: http://harvardforest.fas.harvard.edu/blog/what%E2%80%99s-out-there-small-yet-large-study-harvard-forest . Kalaina was a total rock star and tagged over 1300 seedlings as part of a new project within the Harvard Forest ForestGeo plot that is within the National Ecological Observatory Network (NEON) footprint at Harvard Forest and is also part of a greater global Smithsonian network of forest plots (http://www.forestgeo.si.edu/).

Dr. Sydne Record organizes working group for the next generation of NASA data products

Dr. Sydne Record and postdoc John Grady are out in Santa Barbara, CA this week at the National Center for Ecological Analysis and Synthesis. Dr. Record and collaborators from Michigan State Universtiy are leading a working group of 15 scientists from around the USA and internationally to develop recommendations for NASA’s next set of geodiversity data products for biodiversity scientists.

NASA NCEAS Remote Sensing and Biodiversity Working Group

With new funding from NASA Dr. Sydne Record is organizing a working group at the National Center for Ecological Analysis and Synthesis in Santa Barbara, California. The goal of this working group is to identify the spatial and temporal scales of NASA data products that are most relevant to biodiversity scientists. Insights from this working group will inform NASA’s decisions on what Earth science data products to create for widespread dissemination to the public.

There are a couple of spots open in the working group for graduate students, postdocs, or faculty members. For more information, please, go to http://communityecologylab.weebly.com/uploads/3/9/6/3/39633683/zarnetskedahlinrecord_nasa2016summary.pdf .
