A View of Bird Rookery Swamp- “A fun day for Otters”

Below are first hand observations from our volunteer Dick Brewer. He does weekly visits to Bird Rookery Swamp and very week sends us incredible stories of the magical 12 mile loop. If you would like to see more of his observations visit: http://www.dickbrewer.org/CREW.html

Saturday, February 21st- Fun day for River Otters. One was just past Ida’s pond where I’ve seen it before. It came up on land, rolled in some leaves, and went to the base of a tree. Then, it jumped into ferns at the base of the tree. I didn’t know that otters could jump. It was pulling dead vegetation out and eventually made a small pile of leaves and vegetations and then
marked its territory.

 

The second group was a family by the dual culverts between markers 6 & 3. There was a large gator dozing by the entrance to one of the culverts and the otters were apparently teaching the young about predators. They were huffing, snorting, and barking and then harassed the gator by dashing at it and in a few cases touching its hindquarters. The gator finally had enough and raised its head, at which time all of the otters dispersed, still very noisy. A couple of bikers came by and were totally entertained.

Wild File Q&A: Why do turtles spread their legs and feet out when they rest on logs?

Q: Why do turtles spread their legs and feet out when they rest on logs?

A:      Turtles are cold-blooded animals, so they cannot control their body temperature internally. The only way they have to raise their body temperature is to bask to absorb warmth and vital UV rays. While heat is radiated to their bodies from their shells, they often stretch out their legs to collect additional heat.

Usually, their feet completely widen out at the same time to increase the surface area even more. They are able to engage in thermoregulation and their metabolism functions become elevated. As a result, the efficiency of their immune and digestive systems increases. Another benefit is that they absorb important UVB rays in sunlight. UVB rays become metabolized into vitamin D3 which is necessary to process calcium.

Sharing the Trails with Children

Winter is one of our busiest seasons for environmental education programs out on the CREW Marsh Trails. So, don’t be alarmed if you find yourself on the trails along with 120 kids.

The CREW Marsh Trail is an  exciting outdoor classroom for kids from both Lee and Collier Counties. Jessi Drummond,  our Environmental Education Specialist, takes 3rd graders out on a “Walk through the Watershed” where they spend time dip-netting, getting to know where their water comes from, and the importance of protecting the Corkscrew Regional Ecosystem Watershed.

Ricky Pires,  from FGCU’s Wing of Hope  Panther Posse Program, brings 4th and 5th grade students to the CREW Marsh Trails to teach them about the Florida panther, its habitat and research. FGCU college students help to lead the Wings of Hope field trips, giving them valuable service-learning experience.

Both of these programs, plus a variety of private and home school groups use the CREW trails to help educate the kids of all ages about CREW. As part of our mission to protect the Corkscrew Regional Ecosystem Watershed, these educational programs are important to developing support for the watershed and engaging people in its protection.

So, remember, the next time you go out to the CREW Marsh trails on a weekday from 10 AM to 1 PM, you may find kids exploring nature. Be glad they are there.

Anyone is welcome to come see the magic in action and experience the joy of children outdoors. For more information on CREW’s Environmental Education programs, click here.

 

February Strolling Science Seminar: Gopher Tortoises

Get ready to meet one of Florida’s most important keystone species – the Gopher Tortoise – at CREW’s Strolling Science Seminar (SSS) on Saturday, February 7th at the CREW Cypress Dome Trails . This exciting strolling seminar – The Gopher Tortoise: How protecting one species actually protects hundreds – will be led by FGCU biology instructor, Dr. John Herman. Registration is required, sign up here.

Dr. John Herman’s enthusiasm for reptiles is contagious and his first-hand knowledge is vast. Don’t miss this chance to learn science from one of the best.

Gopher Tortoises are called ecosystem engineers because they fundamentally change the environment where they live by digging burrows. Their burrows provide critical habitat for over 300 other species. We will investigate these burrows and get to know many of these co-inhabitants. Whether you love reptiles, amphibians, birds, mammals, insects, or plants; this seminar will have it all, thanks to the mighty Gopher Tortoise!

What to wear/bring: Wear comfortable outdoor walking clothes and closed-toed shoes. Please bring water to drink and to use to rinse hands. Also please avoid putting sunscreen, lotion, hand sanitizer, or any other chemical on the palms of your hands during this session.

Are there age limits for this event? Yes – this walking seminar is for adults, ages 18 and over.

Do I have to bring my printed ticket to the event? No. We like to conserve resources, so print tickets will not be issued. Just check in with the CREW staff when you arrive.

Wild File Q&A: What causes the small brown and yellow patches on healthy plant leaves?

Q: What causes the small brown and yellow patches on healthy plant leaves?

A:   

It’s often apoptosis, a term that comes from plant kingdom where the Greek apoptosis originally meant the loss of petals of leaves. Now, it can refer to both the plant and animal kingdoms and is also called Programmed Cell Death (PCD).

Cells in plants and animals can self-destruct when they are no longer needed or if they are damaged. For plants, this achieves and maintains stability within the internal environment when it is dealing with external changes.

Natural PCD (not caused by external factors) includes the timely death of petals after fertilization and the senescence of leaves. Host-controlled PCD is also a means of resistance to pathogens. Cells challenged by pathogens initiate a hypersensitive response, which is a rapid PCD process that is activated in order to inhibit the spread of invading pathogen.

PCD in plants has a number of molecular similarities to animal apoptosis, but it also has differences. The most obvious is the lack of an immune system to remove the pieces of the dead cell.

Greatly simplified, instead of an immune response, an enzyme is activated that destroys the central vacuole (a bubble-like cavity) in the plant cell, which is followed by disintegration of the rest of the cell. This creates a protective, dead “envelope” around the pathogen to limit its spread. This is what may appear on some leaves as a yellow and brown blotch.

Some examples of apoptosis in the animal kingdom include the resorption of the tadpole tail at the time of its metamorphosis into a frog, the removal of tissue between fingers and toes of the fetus as it develops, the elimination of T cells that might otherwise mount an autoimmune attack on the body, and during the pupal stage of insects that undergo a complete metamorphosis, the death of most of the cells of the larva which provide nutrients for the development of the adult structures.
