Essential Alligator Gar Research Underway in Oklahoma

By Craig Springer, USFWS Lake Texoma lies over the Texas – Oklahoma state line. This boundary water is enormous. Denison Dam backs up the Red and Washita rivers for miles.

Repeat Spawner Series: The 7 Wonderful Gar of the World

Years of new jobs, new towns, and new people. An uncertain and tight job market. Wondering which side of the country you’ll move to…

Starless Seas – Where have all the stars gone?

By: Dana Sackett A sea star is not usually the first example that comes to mind when picturing a voracious and fearsome top predator. However, many sea stars, the star-shaped echinoderms colloquially called “starfish” and often found in beach-motif decor, are just that: awesome top predators.  Moreover, many sea star species are keystone species, or…

Good addition? Or bad invader? Chinook Salmon in South America

Throughout North America, ongoing resource management and restoration projects aim to conserve Chinook Salmon because their populations have been threatened by many ecological factors, including habitat change, high harvest rates, and hatchery influence. In contrast, these fish are known as an invasive species in the Southern Hemisphere, having been introduced (and continuing to spread) to rivers of the Patagonia and Magellan regions of Chile and Argentina…
