Hans Hofmann explains how environment and genetics influence the brains and behavior of cichlid fish

submitted by: nsf
Hans Hofmann of the University of Texas, Austin, is researching the influences of environment and genetics on the brains and behavior of cichlid fish. Cichlids provide excellent model organisms for such studies because thousands of species of cichlids have evolved; many of these species are genetically similar but behaviorally and socially different from one another. Hofmann is using the diversity of cichlid species to help identify which genes regulate various behaviors and evaluate how...

Melina Hale explains how her research of zebrafish is helping to advance brain research

submitted by: nsf

Melina Hale of the University of Chicago is studying neuronal circuits in zebrafish that generate startle responses. Because little is known about how circuits operate in any organism and because startle responses are controlled by relatively simple circuits, an improved understanding of the circuitry of the zebrafish's startle responses is expected to help lay the groundwork for research on more complicated circuits.

Science Nation - Purple Marsh Crabs

submitted by: nsf
If you take a quick glance at the marsh next to Saquatucket Harbor in Harwich Port, Massachusetts, you will notice right away that some of the grass is missing. The cordgrass there, and all around Cape Cod, has been slowly disappearing for decades. "The cordgrass that's being destroyed here is the foundation species that builds salt marshes," explains marine ecologist Mark Bertness of Brown University. With support from the National Science Foundation, Bertness studies this critical...

Science Nation - Marshes and Sea Level Rise

submitted by: nsf
With support from the National Science Foundation, Villanova University marine scientist Nathaniel Weston studies how both land use and climate change can impact habitat in tidal marshes, including how rising sea levels may affect microbes and other plants and animals. Rising sea levels can actually cause marshes to grow in very different ways. His experiments are already simulating different amounts of sea level rise in several tidal creeks in the Delaware River estuary. He studies how...

Aquariums Relieve Stress for Cancer Patients

submitted by: mdanderson

The University of Texas MD Anderson Cancer Center has 63 aquariums in waiting areas throughout its campus, three of them being saltwater fish. Employees at MD Anderson share their stories about the calming affects the aquariums have on its cancer patients, care givers, visitors and employees.

Marine biologists employ genetic barcoding in the quest to positively identify fish species

Kaleidoscope Project

submitted by: Doorbell Productions

A proposal for an interactive process that integrates myth and science regarding water-culture awareness. If science and myth are reconciled, we believe that synthesis can occur within communities in ways that enable collaboration, trust building, and local water policy change, especially where common pool resources are a concern.
Kaleidoscope Authors: John Klock, Ana Lu Fonseca, Denise Elston, Sarah Sheldrick, and Brock Tabor
