Coming to ‘terms’ with species invasions

Believe it or not, fish don’t care what we call them. However, terminologies associated with certain species can affect how society perceives their importance and impact. Naturalists have been interested in the effects of species introductions just as long as we have been moving species around. In that time, species introductions have had a variety…

A Breath of Fish Air

I recently migrated from Michigan to Louisiana to join the faculty at Nicholls State University as assistant professor. Moving from the Great Lakes to the bayou is inevitably laced with logistical concerns; in this case they included mobilizing myself, my wife, all our stuff, and…my fishes. That’s a two-day trip across ~1200 miles, but I…

Happy BOFFFF Day!

While mama fish may not have the same maternal instincts of our own dear mums, they do their part to sustain fish populations, particularly BOFFFFs. “What is a BOFFFF?” might you ask…A Big Old Fat Fecund Female Fish.

Yellow Perch and the hypoxia Goldilocks zone

It may seem obvious that suffocation is not good, but determining a fish’s tolerance for low oxygen is increasingly important as hypoxia increases worldwide. Hypoxia (low dissolved oxygen concentrations) occurs naturally—it develops in the hot summers and cold winters beneath ice in small lakes and ponds. Hypoxia can also occur as a result of human…

How climate impacts microorganisms and why we should care

By: Dana Sackett As Earth Day approaches, it seems timely to pause and examine some of the natural processes that enable life on Earth.  Remarkably, this big topic requires us to take a look at some of the smallest organisms on the planet.  Microorganisms (or organisms that cannot be seen with the naked eye such…

Spawning in strange waters: how hybridization affects native fishes

By Ed Kluender, guest blogger Hybrid creatures are one of the most common tropes of both goofy and great horror movies (think The Fly or countless werewolf movies), and plenty of them are at least half fish – Creature, Piranhaconda, and the Sharktopus franchise. Most of those films have a pretty shaky basis in reality,…
