This National Science Foundation project grant of $139,432 awarded on May 1, 2022 will fund research into the hydrodynamic consequences of spines on zooplankton morphology and function under the Biological Sciences program (CFDA 47.074). Specifically, the award to the University of California, Berkeley supports a collaborative research effort between the university and a small liberal arts undergraduate college to examine the ecological functions of spines in different barnacle nauplii larval...
This National Science Foundation (NSF) Biological Sciences program (CFDA 47.074) Project Grant award of $1,022,535.00 to George Washington University will fund a research project on the phylogenomics and evolution of sexual systems in barnacles. The key products will be: A robust phylogenetic framework for all known barnacle species, which will be integrated into online resources like the Open Tree of Life. This will provide a much-needed evolutionary context for studying the diverse...
This Project Grant award from the National Science Foundation (NSF) Biological Sciences program (CFDA 47.074) provides $535,465 to Trustees of Tufts College (Tufts University) for a collaborative research project titled "Biodesign: A Deep Dive into Dynamic Damping in Extreme Underwater Maneuvering". The primary goal is to investigate how fish achieve rapid maneuvers that exceed the capabilities of advanced robotic systems, focusing on the hypothesis that fish can dynamically modulate...
This $115,936 Project Grant awarded by the National Science Foundation (NSF) Geosciences Program (CFDA 47.050) supports fundamental research on the evolutionary history and species delineations of coronuloid barnacles (arthropod crustaceans) that are epizoic with marine megafauna like sea turtles and whales. The key research objectives are to: 1) construct a phylogeny mapping the evolutionary chronology of barnacle attachment mechanisms (gluing, gripping, gouging); 2) compare global...
This federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $101,855 to the College of Charleston to conduct collaborative research on the evolutionary history and host-adapted diversification of barnacles epizootic (living on the exterior) with marine megafauna such as sea turtles and whales. The research aims to 1) study the genetic tags and evolutionary history of barnacle attachment mechanisms, 2) assess the potential use of barnacles as...
This Project Grant award from the National Science Foundation (NSF) Biological Sciences program (CFDA 47.074) supports research at the University of Wyoming to study the evolutionary effects of fish predation on zooplankton in high mountain lake ecosystems. The $307,371 award will be used to quantify differences in the elemental composition and nutrient cycling between zooplankton populations in lakes with and without introduced trout. The project aims to improve understanding of the impacts...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $742,863 to the University of Washington for a collaborative research project titled "Rhythm and Blooms: Deciphering Metabolic, Functional and Taxonomic Interactions over the Life Cycle of a Phytoplankton Bloom." The research aims to explore how environmental factors and interactions between phytoplankton cells and associated bacteria control the timing of phytoplankton bloom...
This National Science Foundation (NSF) Project Grant award under CFDA program 47.074 Biological Sciences provides $240,000 in funding from July 1, 2025 to June 30, 2028 to support a postdoctoral research fellowship. The award will fund research investigating the anatomical, physiological, and behavioral mechanisms used by bony fishes for buoyancy regulation. The research aims to develop a predictive model of buoyancy regulation strategies based on fish ecology and phylogenetics. In addition to...
This federal Project Grant award of $626,837.00 from the National Science Foundation's (NSF) Biological Sciences program (CFDA 47.074) supports collaborative research at Stony Brook University to investigate the role of phenotypic plasticity and natural selection in the early stages of new species formation in threespine stickleback fish. The research will examine recently-established freshwater stickleback populations near Anchorage, Alaska that have diverged from their marine ancestors,...
This $245,860 Project Grant award from the National Science Foundation's Biological Sciences (CFDA 47.074) program supports collaborative research by Providence College to investigate how fish achieve rapid, highly maneuverable underwater movements. The research focuses on testing the hypothesis that fish dynamically modulate their body damping (resistance to bending speed) and stiffness to enable these extreme maneuvers, which surpass even state-of-the-art robotic systems. Through a combination...

This federal Project Grant award of $231,912.00, funded by the National Science Foundation's (NSF) Biological Sciences program (CFDA 47.074), supports research to investigate the hydrodynamic consequences of spines on zooplankton, with a focus on the larval stage of barnacles.

The key objectives of this research are to: (1) determine the functional impacts of spine presence, location, and morphology on hydrodynamic forces and torques; (2) evaluate how spines and appendage kinematics affect swimming, sinking, and feeding performance; and (3) examine the hydrodynamic changes as barnacle larvae transition from the planktonic nauplius to the settling cyprid form. The project leverages a collaborative partnership between the University of Washington, a major research university, and a smaller liberal arts college to conduct experiments using micro-videography, particle image velocimetry, and dynamically scaled physical models. Findings from this research will advance the understanding of how tradeoffs between ecological functions shape the evolution of zooplankton form and inform the development of bio-inspired aquatic microrobots. The award period is from October 1, 2024 to April 30, 2025.
