New R package RSPPlme4 goes online

A new R package for analysing spatial point patterns has just been made public from the labs github site. The new version uses the lme4 package to fit linear mixed effects models, speeding up performance dramatically. The new package has much more intuitive syntax, including a function klmerHyper that fits the models, confint that computes confidence intervals on parameters and predictions and anova that quantifies the contributions of parameters to explaining the overall variance.

Welcome Lee!

We are delighted to welcome Leone Brown to the group as a Postdoctoral Research Associate. Lee is going to be leading the NSF-funded project on the impacts of forest fragmentation on tritrophic interactions in Connecticut. Lee joins us after completing post-docs at the University of Georgia and Tufts/Harvard and her PhD at Stony Brook.

Bird survey technician position in the Bagchi and Elphick labs

The Bagchi and Elphick labs are looking for BIRD SURVEY TECHNICIAN to conduct forest bird research in Connecticut. The technician will conduct forest bird surveys (point counts, etc.) in forest fragments throughout Connecticut, and should expect challenging conditions with daily pre-dawn starts, heat/humidity, biting insects, ticks, poison ivy, etc. The ideal candidate will (1) be able to identify New England forest birds by sight and sound, (2) have previous experience conducting point count surveys, (3) be familiar with GPS and map navigation, (4) be self-motivated and physically fit, (5) have a positive attitude, (6) work well with minimal supervision, both independently and as part of a team, and (7) be capable of conducting data entry efficiently and carefully.

Bird surveys will be conducted as part of a large project investigating the impacts of fragmentation on ecological networks in temperate forest ecosystems in the northeastern United States. The study seeks to develop a mechanistic understanding of fragmentation-induced shifts in the structure of ecological networks involving herbivorous caterpillars, and their host-plants, parasitoids, and predators. Technician may be required to help with other aspects of the larger study, as time allows.

Salary ranges from $420-$480 per week, depending on experience. Technician must provide their own vehicle, but all mileage will be reimbursed at the standard rate set by the state of Connecticut. Position is for approximately two months beginning approx. 10th May 2017 (exact dates are somewhat negotiable).

To apply, please send a cover letter and CV with contact information (email and phone) for three references to Chris Elphick, Please include “FOREST BIRD TECH” in the email subject line and include your last name at the start of the name of any submitted documents (e.g., Elphick_CV.pdf). Review of applications will begin immediately.

Welcome Shihong!

We welcome Jia Shihong, who joined the group as a visiting scientist from the Institute of Applied Ecology, Chinese Academy of Sciences. Shihong will spend his time in the group analysing his data on the roles of biotic and abiotic factors in shaping seedling community dynamics at Changbaishan Mountain in northeastern China.
