While students in the Science and Society senior seminar were performing a peer review of their senior theses, Dr. Sydne Record had a chance to join colleagues in Knoxville, TN at the National Institute for Mathematic and Biological Synthesis to work on a book about remote sensing of plant biodiversity that will be published by Springer. Dr. Record’s contribution covers her NASA funded research investigating the relationships between biodiversity and geodiversity. Stay tuned for information about the book release next year.
The Long Term Ecological Research Network All Scientists Meeting was held this past week in Pacific Grove, CA. Dr. Sydne Record presented research from a cross-site LTER REU collaboration with REUs, Kyra Hoerr BMC ’20 (mentored by Sydne) and Cameo Chillcut (mentored by Phoebe Zarnetske). Dr. Record also had the chance to run a workshop on synthesis of long term community data based on work she is doing with the LTER Metacommunity Synthesis Group at the National Center for Ecological Analysis and Synthesis. What a fun week of science, whales, and sun!
Nia ‘Blue’ Riggins (BMC ’20) researched the relationships between seedlings, ants, and soil pH at Harvard Forest this summer as part of the REU Program with Dr. Sydne Record. Check out her blog post about her upcoming comic book about her experience entitled, “Blue vs. Wild.”
Congratulations to Nia ‘Blue’ Riggins for her nomination as a Francis Velay Summer Research Fellow! This summer Nia is conducting summer research with Dr. Sydne Record at Harvard Forest on tree seedlings and their responses to light and soil pH. As a biochemistry major this opportunity enables her to explore the linkages between biology and chemistry through an ecological lens.
Last week postdoctoral fellow, John Grady, in the Record Lab found out that a NSF proposal he wrote for the Rules of Life program was funded! This will provide support for John to do a second postdoc with Dr. Tony Dell at the National Great Rivers Research and Education Center. Congralations, John!
Each year the Record Lab migrates to Harvard Forest for our summer field season. Check out Kyra Hoerr’s blog/podcast describing her work on reconstructing land-use histories of co-located LTER-NEON sites here.
Last week Dr. Sydne Record had the opportunity to present research from a NASA funded working group she is leading along with Phoebe Zarnetske and Kyla Dahlin from Michigan State University on the relationship between biodiversity and geodiversity in Washington D.C. at the NASA Biodiversity and Ecological Forecasting Team Meeting. It was a great week of thinking BIG in ecology using global NASA data products.
Many ecologists and conservation biologists use species distribution models to predict where species should live based on factors like temperature, precipitation, and habitat. This technique is really important for species or habitats that are hard to sample. If we want to conserve or protect these species, we need to have better information about where they live, thus we use models. However, using a survey of the literature from 2003-2015 we found that these studies are mostly being done in: 1) terrestrial systems (over 85%; few in marine or freshwater ecosystems), 2) North America or Europe (few studies in Africa, Asia), and 3) on plants, birds, or mammals (few on fish, amphibians, reptiles). We also found that scientists have been slow to incorporate factors into models that could greatly affect species distributions, such as dispersal and interactions with other species (e.g., competition, predation). Importantly, very few studies reported the results of the models with and without these biological factors, making it difficult to know how important these factors might be now and in the future. Additionally, nearly half of studies did not use the model to predict where species might live in the future given climate change predictions, which we consider a missed opportunity. Lastly, with a limited set of studies, we found that the overall size of the study area (i.e., extent) and the cell size used in the model (i.e., grain) did not have an effect on the importance of dispersal and species interactions. However, with a small sample size, we interpret this outcome cautiously and encourage scientists planning to use these models to carefully consider decisions about study extent and grain size.
Take home message: Conservation decisions could be driven by incomplete information – we need models of underrepresented ecosystems, taxa, and regions; models that consider the effects of climate change; and models that are more biologically realistic and robust.

Research was funded by the National Science Foundation. The Ecological Society of America sponsored an early career workshop in 2013 that initiated this international collaboration of scientists from USA, Taiwan, and Israel.
Every year the Harvard Forest Long Term Ecological Research Site hosts an annual symposium of all scientists who work at the forest that has been studied for over 100 years in Petersham, Massachusetts. This year Dr. Sydne Record presented her insights on the value of long term ecological experiments and postdoc Dr. John Grady presented a poster on his work on energy partitioning in forests.
The highlight of the day for Sydne was meeting up with Tess McCabe (BMC ’15, former Harvard Forest REU) who is working on her PhD in the Dietze Lab at Boston University.
