MHS Member Profile

by Drew Newman Marilyn Brooks - Treasurer

One of the neat things about doing this column is meeting new people andJeaming new things.

Since having joined MHS I've wondered about what the Board of Directors is and what it does.

Having spoke with Marilyn, I'm able to share some of her insights with you.

Marilyn has been with MHS for 4 years and has been on the board in the position of Treasurer for I year. She has also served as Student Chapter President and has been Committee Chairperson for he Holiday Banquet as well as on the committee for the Midwest Herp Symposium. She is currently the coordinator for newsletter assembly.

Marilyn explained that actions taken by the board are made by majority vote. Policies enacted by voting are known as standing rules. Marilyn, at present, is working on compiling all standing rules. The board also makes decisions on how to appropriate donations solicited by other organizations. The maximum we can give is 500 dollars in one year. Of that, 350 has to go for in.. state needs. A few examples of things we would donate money for would be conservation and education. Funds continue to be a problem with the loss of our food animal sales. Recently we began selling books which is helping, but the board is always open to new ideas to supplement our income. Income is used to offset expenses such as the newsletter. One thing the board plans to pursue is the making of a video which will be available to companies and organizations who we may solicit for grant money.

Marilyn feels that we need more people to volunteer to prevent burnout experienced by people who . are taking on a lot of commitments. She is also concerned that some people see a /I clique" among MHS members that do volunteer. There is no clique, she claims, just people who get to know each other through various functions. She emphasizes that anyone is welcome and encouraged to come

and get involved.

On a closing note I might add that all board mee1ings are open to the general membership. All you have to do is to speak to the President, John Meltzer, in advance.

Hands-On Update

by Bill Moss On July 16 we had a very successful Hands-On at the General Mills company picnic in Plymouth.

The tum out by MHS was fabulous with Donna Calander, Glen Jacobsen, Vence and Nanette Jimerson, Scott and Cheryl Cords, Nancy Haig, Terry Schieber, Greg . Kvanbeck, Marilyn Brooks, Lynn Pairer, Cliff Lindberg, and Drew Newman, who did the organizing in my absence. Dave Sattman from General Mills was very complementruy on the way the MI1S people conducted themselves and on the open and friendly way the MHS volunteers interacted with the General Mills employees. He told me that he would be happy to invite us out again. Last but not least, General Mills donated $125.00 to MHS for our time. Thanks everyone for making this a good show.

Another reminder about the Renaissance Festival. By the time you read this newsletter, there will still be at least four weekends left路out at Festival so it's not too late to get out and join the foo.

Remember, you let me knOVl at least one week in advance of the weekend(s) you want to pat1icipate so Festival can plan for you. Call me at 488-1383 to make a reservation or with any questions you may have. I have a number of costume books available if you are planning to make a costume, otherwise there are some costumes available at Festival.

On another subject, there seems to be some confusion over what the MHS policy is regarding animal handling at hands-on events. Our policy is that the head of an animal never be presented to the public. Offering the rest of the animal for hands-on is fine. Even if you really know your animal, you have to protect against any possible actions the person standing in front of you may take. Some of them will do some really stupid things. If anyone were to be bitten, it would not be the animals fault or the persons fault. It would be you as the handler who would be at fault. To steal a line, "Hey, let's' be careful out there! II

MUS Brochure Revised A committee consisting of Joe Matzke, Bill Moss, and Jo Anne Wetherell-Moriarty recently completed updating the MHS Brochure. The brochure is used to let perspective members know more about MHS. Special thanks to Joe for his design and artwork. Text and layout were done by Bill and Jo Anne.

Any member wanting brochures for to hand out at programs or nature <;enters should see Dennis Daly.

Cage Heaters (Part 1)

by William Ness Providing an appropriate environment is a major factor in the successful maintenance of reptiles and amphibians in captivity. Creating the artificial environment consists of a number of factors including choice of building materials, substrate, lighting, appropriate plants (if any), access for routine feeding and maintenance, viewing areas, privacy areas, and method of providing the appropriate temperature. This series of articles will attemptto deal with some of the options for maintaining the appropriate temperature in an enclosure for reptiles or amphibians.

The easiest and probably most widely used method of heating herp cages is the conunon incandescent light bulb. While this method is often used .quite successfully there are a number of considerations that should be addressed. First, although the initial investment is quite low, bulbs will have to be replaced periodically so there will be an ongoing expense. One important thing to think about is the placement of the socket in the cage. Some times the cage design will dictate this option. If you are using an aquarium for a cage the obvious choice is to either use an aquarium hood or mount a light socket on a perforated board that serves as the top of the cage. It is usually recommended to mount the socket off center so there will be a thermal gradient within the cage. In a wooden cage the socket can be mounted on the top, ends, or back of the cage. If the light is mounted on the back wall or on one of the ends it is very likely that it will be used as a perch by some herps with the possibility of bums from the light bulb. Also, snakes crawling over the .light bulb have a tendency to unscrew the bulb or even break it I prefer to mount the light socket on the top of the cage when possible. Mounting the light on the top does not always prevent snake sabotage, however. One of my boas (Tess, the remodeler) manages to rip light bulbs out of their ceiling mounted sockets about once every month or so. Using straight aquarium bulbs may reduce the probability of this occurring (but not for Tess, she would just see it as a new challenge). When cages will be stacked it may be preferable to run the power cord out the back or end instead of the top of the cage. I run the wires along the inside top and out a hole through the back or end, and use a lot of glue to hold the wire securely in place. When only wire staples were used to attach the wire my snakes tended to get between the wire and the roof of the cage. I have had smaller snakes apparently trapped this way, and of course Tess uses the opportunity to rip things down. Glueing the wire to the ceiling of the cage prevents snakes or lizards from getting into this kind of trouble.

In larger cages, several light sockets should be used, but arranged to provide a thermal gradient In fact, if only light bulbs are used for heat it is a good idea to always use two light bulbs. This way if one bulb burns out (or gets broken by Tess) there will still be some heat from the other bulb and the cage will not be chilled as much. Using two lower wattage bulbs to maintain the temperature instead of one high wattage bulb will decrease the chance of burns from contact.

I like to run the power cord for the lights through a dimmer switch so that I don't have to keep trying different wattage of bulbs to get the desired temperature. The dimmer also allows for day/night temperature variation without completely cooling down the cage, and allows me to adjust temperatures to compensate for seasonal variations in my snakeroom temperatures without having to change to different wattage bulbs.

Some of the drawbacks of incandescent light bulbs as a heat source include the inability to photoregulate cages in a cool room, frequent replacement costs of bulbs, the possibility of animals getting burned, the possibility of injury from broken glass if an a.nimal breaks the bulb( Tess hasn't cut herself, yet), and, with the concern for energy conservation, inefficient use of electricity (much of the energy is converted to light). One other consideration is the effect of continuous exposure to light. This may be a detrimental factor for some 5pecies, although I have a female Common boa constrictor (Tess again) that produced 24 young after being kept in continuous light for about

fIfteen years and then switched to a day night cycle for a few months. Incandescent light bulbs can be, and have been, used effectively as a heat source for reptile and amphibian cages as long as the factors mentioned above are taken into consideration.

There are a number of alternatives to using incandescent light bulbs as the sole source of heat for reptile and amphibian cages. The next article will discuss some of the options available and their advantages and disadvantages.
