Kloe Borja wins 1st place in the Island-wide STEM Fair!

Photo by Amanda Santos
EBL's 2016 Step-Up student,  Kloe Borja won first place at the CMNI Island-wide STEM Fair this weekend. She conducted her project on avian gut passage times to predict which bird species would best disperse seeds into degraded forest if reintroduced to Guam.

For her next step, Kloe will be one of approximately 1,800 high school students from around the world to compete in the Intel International Science & Engineering Fair in Los Angeles in May. 

Check out the article about Kloe in  the Saipan Tribune here:

Strong work, Kloe!!

New paper out today!

This study has been long in the making, but is finally here! We describe the impact of frugivorous bird loss on seed dispersal and recruitment in two forest tree species. This is my favorite figure from the paper, thanks to collaborator, Eric Buhle.
Figure 3 | Dispersal across the landscape. Seed dispersal kernels of (a) Psychotria and (b) Premna on Guam as compared with three nearby islands where forest birds are present. The fitted kernel models were used to predict seed rain in a hypothetical forest plot. Panels c,d depict seed rain in forests with frugivores, and panes e,f depict seed rain in forests without frugivores. Shading indicates the mean seed density (seeds m - 2, note logarithmic scale) arriving at each location on the forest floor. Circles indicate crowns of conspecific adult trees.

Flashback to Summer 2016, gut passage experiment


Here are three of our biologists (Kloe Borja- Kagman High School, Amanda Santos - Oregon State University, and Joma Santos - University of Guam) from this summer working on sorting seeds from our gut passage experiments with captive forest birds. We fed seeds of over 20 tree species to captive Mariana fruit doves, white-throated ground doves, Micronesian starlings, bridled white-eyes, and golden white-eyes to see how gut passage affects germination.

Local conference presentations

We had a busy week for conferences in the Mariana Islands. On Monday, Haldre and our high school STEP-UP intern, Kloe Borja, presented at the Asia Pacific Academy of Sciences, Science Education, and Environmental Management.  And on Tuesday at the annual Brown Treesnake (BTS) Technical Committee meeting on Guam, Haldre gave a talk on which tree species are likely to be winners or losers in Guam's forests without targeted management actions. There was a lot of excitement and optimism during the BTS meeting this year - landscape-level BTS suppression using toxicant drops is now feasible, and we are brainstorming ways to reintroduce birds and bats and restore forests on the island. Stay tuned over the next few years... it's possible that the agencies and researchers working on this problem will turn this conservation disaster into a conservation success!

Looking for a lab manager!

Do you love organizing large, complicated projects? Do you want to develop your experience in project management and field research in an academic setting? Are you excited about splitting your time between a great little town in Iowa (Ames) and the Mariana Islands? Do you want to be around a bunch of inspiring students and researchers focused on conservation and global change?

Apply to be the Rogers Lab Manager. See here for more details.

Calling all prospective graduate students...

I am looking for one MS or PhD student interested in studying the role of non-native seed dispersers in the Mariana Islands. These species, including feral pigs and rats, are typically thought of as highly detrimental invasives in island ecosystems, but in the bird-less forests of Guam, they may be performing a unique role as seed dispersers. This student would develop a project assessing the contribution of non-native pigs and rats to seed dispersal of native tree species. The student would apply to the Ecology & Evolutionary Biology Graduate Program at Iowa State University, and would join the Rogers lab. They will be funded through a research assistantship for four semesters, and will be expected to TA for the remainder of their degree.
