The Carnivorous Plants of
South Louisiana

ABITA SPRINGS, LOUISIANA -- (source: WGNO, see the video) There are many scary things from politics, to clowns to spiders. Sometimes the creepiest things don't go bump in the night. They might not even move at all.

The hallmark of the plant world is the ability to use sunlight to make food during photosynthesis. In the long leaf pine savannah of south Louisiana, a few plants have evolved a curious method of getting nutrients from poor soil. They've become carnivorous.

Dr. Christopher Reid is a botanist and educator at LSU's School of Renewable Natural Resources and says and is intrigued by the plants and their relationships with other organisms. Dr. Reid says, "the fact that plants interact with animals in such a away as to trap them and consume them... usually, it's animals that eat plants."

There are over a dozen species of carnivorous plants in the area. They are part of the biodiversity of hundreds of plants that live under the pine trees. All of the plants in the area usually rely on routine forrest burns that clear the tall vegetation and keep shrubs from getting to dense. This allows the opportunity for many species to get their time in the sun and thrive. Carnivorous plants take advantage of the forrest fires and survive remarkably because of their buried rhizome. Even though the top of the plant may get burned, they will come up again.

The largest carnivorous plant in the area is the yellow trumpet pitcher plant and in it's modified leaves there is something similar to stomach acid that helps break down the insects that fall into the trap.

As wonderfully awesome as Little Shop of Horrors is (including the godly voice of Levi Stubbs), these plants aren't mean green mothers from outer space. Carnivorous plants have been around for millions of years and each one has their own unique way of eating. Some pitcher plants even secret a narcotic that paralyzes prey. Others like the plants like sundews have tentacles and use a fly-paper method. "The leaves of the sundew are covered with hairs that are gland-tipped. The glands secret a sticky substance. One of the features that pitcher plants have are these downward pointing hairs, which prevents whatever falls in to the digestive enzymes from crawling out," says Dr. Reid.

The Abita Creek Flatwoods Preserve has a pitcher plant trail which is hikeable and it includes parrot pitcher plants which become quite showy when they bloom with their otherworldly crimson blossoms. During spring, the preserve is full of nature's color, as the land blushes with the blooms of carnivorous plants and other flowering vegetation in the long leaf pine system. The preserve is free and open to the public from sun up to sun down.

Shockingly, as deadly as carnivorous plants may seem to insects, some arthropods have evolved to live inside of the pitcher plant for protection and there is even a species of moth that lives its whole life cycle inside the pitcher plant trap. Some spiders have evolved to build webs at the openings to steal the meal of the pitcher plants.

Simply put, nature is wild, sometimes ravenous, but always remarkable.

High river pushed more CO2 into atmosphere

Dr. Yi-Jun Xu

(10/01/19) BATON ROUGE, La. — Many scientists believe rising levels of carbon dioxide in the atmosphere are contributing to climate change. The increase may be related to the frequency that water moves from the ground into rivers and then into the air before returning to land as rainfall.

This water movement is called the hydrologic cycle, and an intensifying hydrologic cycle could increase global carbon cycling, said Yi-jun Xu, a hydrology researcher in the LSU AgCenter.

Xu is finishing up a short-term study of the carbon cycle on the Mississippi River.

Initially working with an earlier grant from the National Fish and Wildlife Foundation to study pollution and water quality, Xu began sampling carbon concentrations in the Mississippi River when the record-high flood began in February 2019.

Louisiana Agruculture Magazine
Spring 2019

Louisiana Agriculture Magazine, Spring 2019

The spring 2019 issue of Louisiana Agriculture focuses on the “birds and the bees” and the importance of reproduction and breeding to the success and profitability of our agriculture industry. LSU AgCenter scientists are dedicated to finding ways to not only improve plants and animals on the farm but also in nature to enhance and sustain our environment. See below for links to the articles. If you would like to subscribe to the print copy, or if you have any questions, or if you want to unsubscribe from this list, please contact the editor, Linda Benedict. The LSU AgCenter is here to serve you.
