Clasper appendages discovered in mid-Cambrian trilobite show horseshoe crab-like mating behavior

May 6, 2022

Fossils can tell scientists a lot about an animal such as their morphology, their environment, and where to place them in the tree of life. One thing though that’s very difficult to observe in the fossil record is an animal’s reproductive behavior. It takes a very uniquely preserved fossil to reveal the secrets behind reproductive strategies in some of the earliest complex animals.

how a genetically defined microbial population adapts across diverse environments

How does a genetically defined microbial population adapt across diverse environments?

June 13, 2022

In a new study in the American Society for Microbiology Journal, PhD candidate Yunha Hwang and Professor Peter Girguis compared the genetic diversity of one of the most abundant marine archaeal populations between pacific and atlantic ocean basins to address a fundamental question of how a genetically defined microbial population adapts across diverse environments. The study revealed that these populations feature distinctly ...

Marine Lichenized Fungi Bioindicators of Coastal Ocean Pollution

March 31, 2022

A new study in Rhodora examined the use of marine lichens to assess water pollution levels in the Boston Harbor. The study led by Liam F. Nokes, a former student at Arlington High School who was working in Donald H. Pfister's lab, suggests that marine lichens could prove useful as bioindicators of ocean pollution, and established a plan for a state fungus. Nokes' (now a student at Dartmouth) proposal is currently under review by...
