LUMCOM

Scientists recently returned from their annual cruise to measure hypoxia in the northern Gulf of Mexico. An area of hypoxia, often called a 'dead zone', is where oxygen levels drop under a critical threshold below which marine life cannot survive.

 

From July 22 - 28, they mapped an area of low oxygen that was 2,720 square miles, about the size of Delaware and smaller than predicted. This is well below the 5,770 square mile average from 2014 - 2018 and only a third the size of the largest hypoxic zone ever measured, which was 8,776 square miles in July 2017.

Probably the most popular kinds of fish in this area are bass, white perch or crappie, bream, and catfish. They are well known because they are fun to catch and good to eat. However, in terms of biological diversity, this group falls at the bottom rung of the aquatic ladder. In Louisiana, there are only two species of black bass, two species of bream-like sunfish. Another group, almost completely unknown even to amid fishermen, swims our rivers and creeks with dramatic diversity of form, color, and species. Collectively, they are called Darters.

Wildlife Values

Most Bayou Diversity programs involve wildlife in some form or fashion.  But who places value on wildlife and just how much is wildlife worth these days?  A recent report issued by the U.S. Fish and Wildlife Service is enlightening.

Wise Ones

We are losing the old wise ones.  Some of our most erudite naturalists never heard a professor's lecture or studied in a biology lab that reeked of formalin and moth balls.  Still, they know the eddies where giant flathead catfish prowl and ridge-top trails of foraging coyotes.

Wild critters walk, fly and swim among us Louisiana folks.  While all are interesting, a few are downright strange, or at least strange looking.  The unusual appearance of some animals is often caused by skin aberrations usually linked to genetic abnormalities.

In teaching kids how to fish, one of the first obstacles that must be overcome is what has to be an innate urge to throw rocks and sticks into the water for the sheer joy of it.  Every fisherman knows that such commotions only scare the fish away.  Within the world of birds though, some of the best fishers actually incorporate this behavior into their pedagogy.

By mid-July the fish and plant collections of the University of Louisiana Monroe Museum of Natural History will hopefully have a new home, according to Dr. Eric Pani, Vice President for Academic Affairs.

Several factors led to the decision to donate the collections, which have been stored in Brown Stadium since the museum was moved to Hanna Hall last year. Many of the specimens are preserved in flammable liquid and must be kept in a facility with a fire sprinkler system.

Fish Migration

Even the most nature-deprived urban dwellers among us are aware of the basic concept of bird migration.  They know that some types of birds fly north in the spring and return in the fall.  However, few people including most outdoor-oriented folks in this region who should know better realize that migration is also a vital part of the life cycle of other kinds of local wildlife.  Consider freshwater fish, for example.
