Deer feeders are common in North Florida, and “deer corn” is sold in multiple markets. Cross-roads convenience stores sell it in plain brown bags and big box stores in town sell it in camouflage bags with three color pictures of giant bucks on the front. With the high price of corn in 2012, many hunters saved a few dollars buying “combine run” corn from local farmers or corn screenings from grain elevators. The corn’s no different, however, either product can contain weed seed, especially Palmer amaranth. These weeds can mean big trouble for farmers and hunters.
Palmer amaranth is a species of pig weed, but it’s not your granddaddy’s “careless weed”. It’s taller than either red root pigweed or spiny pigweed, and is becoming resistant to several herbicides, most notably glyphosate (“Roundup”). Amaranth seed are small and plentiful (1 to 1.5 millimeters in diameter) and easily can fit in the nooks and crannies of grain harvesting and handling equipment.

Once Palmer amaranth seed make it into a deer feeder, there’s a huge opportunity for seedlings to take root in places under the radar of typical scouting and control measures. If these seedlings are herbicide resistant, you’ve done far more harm to the landowner than any savings on corn cost can offset. Conservative estimates indicate herbicide costs have at least doubled due to herbicide resistant weeds. Do your local farmer a real favor; scout and control weeds coming from your deer feeder.

Feeding corn to deer and turkey is permitted by the Florida Fish and Wildlife Conservation Commission as long as the following restrictions are met. “Resident game and wild hogs may be hunted in proximity of year-round game-feeding stations on private lands, provided the feeding station has been maintained with feed for at least six months prior to taking resident game,” and “Wild turkey may not be taken if the hunter is less than 100 yards from a game feeding station when feed is present.” See General Information regarding Feeding Game at http://myfwc.com/hunting/regulations/general-information
American dog ticks are also usually found on dogs but will also attach to other mammals and humans. They also can transmit Rocky Mountain Spotted Fever. American dog ticks can cause paralysis when they attach to the base of the skull or spinal column. Recovery usually occurs within 24 hours of tick removal.
Gulf Coast Ticks are similar to the American dog tick with larger mouthparts. They transmit a less severe relative of Rocky Mountain Spotted Fever. Gulf Coast Ticks are commonly found on the ears of large mammals such as horses and cattle.
Apply Permethrins to clothing and allow them to dry before wearing
Avoid brushing against plants in tick-infested areas
Clear brush along pathways and walk in the middle of pathway
If you are bitten by a tick or develop symptoms, contact your physician. Early diagnosis is best and makes treating tick disease easier and more effective.
Coyotes can be a nuisance to pet and livestock owners as well as vegetable farmers. They are true scavengers and will eat just about anything – sheep, calves, poultry, deer, watermelons, snakes, foxes, cats, rabbits, grass, carrion, pet food…
Although they are mainly active at night, coyotes can be seen during daylight hours close to sunrise and sunset.

Coyotes are brownish gray in color with light gray or cream colored belly. They have erect pointed ears with a slender muzzle and bushy tail. They weigh between 20-45 pounds and are found in deserts, swamps, tundra, grasslands, brush, forests and even in the suburbs. Coyotes become bolder when living in urban areas and can be a threat to pets. Small dogs and pet cats are easy prey. Garbage cans are another easy food source.
So what can you do to reduce the chance of having a coyote conflict?
First, never feed coyotes!
Eliminate water sources near your home.
Place bird feeders out of reach.
Secure garbage containers.
Feed pets indoors when possible and store pet food where coyotes cannot access it.
Trim shrubbery near ground level to reduce hiding cover.
Fence your yard. The fence should be at least 6 feet high with at least 6 inches buried.
Don’t leave small children unattended outside if coyotes have been seen in the area.
Don’t allow pets to roam free, especially at night.
Discourage coyotes from getting too comfortable and close to humans, pets, homes, or buildings – shouting, loud noises or throwing rocks at them normally works. Coyotes generally will not challenge an adult human.
WE NEED YOUR HELP – COYOTES VS BOBCATS: WHAT ARE THEY EATING?
The University of Florida is conducting a study of coyote and bobcat diets in Florida. Your help is needed in this study. Of particular interest is the importance of popular wildlife species, including white-tailed deer, turkeys, and bobwhite quail, livestock, and pets in the diet of these predators. Diets will be determined by examining the stomach contents of coyotes and bobcats legally harvested or obtained in Florida.
We are asking for help in obtaining legally acquired coyote and bobcat carcasses, with or without pelts. We will also accept coyote and bobcat stomachs and intestines if you cannot store the whole carcass. Carcasses or stomachs and intestines should be frozen in a suitable bag or container, and include the name of contributor, animal sex, date harvested/obtained, and location harvested/obtained. We have obtained a permit from the Florida Fish and Wildlife Conservation Commission for this project, and will keep information provided by you for this project anonymous to the extent possible by law. Your assistance with this valuable study is greatly appreciated. Researchers will coordinate combining your animals with others in your area for a pickup or provide instructions for delivery in Gainesville Please contact Lauren Watine (352-846-0558; lnwatine@ufl.edu) or Bill Giuliano (352-846-0575; docg@ufl.edu) at the University of Florida for more information.
Check into the lodge at Wakulla Springs State parkon a crisp cool evening and you are immediately greeted with the warmth of an open hearth fireplace and the security of stone walls radiating comfort and solace. These stately accommodations meet all your needs for refuge and rejuvenation with opportunities for an old fashion game of chess or checkers, great food, and time to reconnect with cherished friends and family.

Wakulla Springs hosts about 200,000 visitors each year and is one of North Florida’s most popular swimming spots with peak attendance between April and August. It’s a great place to beat the heat on a hot summer’s day. The same cool 250 million gallons of 69F degree water that provides welcome relief to visitors on hot summer’s day also provides an inviting warm refuge on winter’s coldest days to another type of park guest, manatees.
Wakulla Springs is the Gulf of Mexico’s northernmost geographic location where manatees congregate and consistently overwinter in large numbers. Last week, park guides estimated 30 individuals in the springs and river run.
Florida Fish and Wildlife Conservation and Commission / Florida Wildlife Research Institute’s winter synoptic aerial survey of Florida’s manatees in 2011 totaled 4,834 individuals. Improved survey techniques have resulted in increased estimates for Florida manatees in recent years, however, they still remain listed as endangered.

Consistent water temperatures below 65F can result in stress, pneumonia, or colds in manatees. Other environmental conditions can also cause problems for manatees. This year, a large number of Florida manatee moralities have been reported as a result of a harmful algal bloom on the Atlantic Coast in the Indian River Lagoon. Florida manatees are also frequently struck by boat hulls and boat motor propellers; the signs of which are often seen in individuals with tell-tale propeller scars.
Education and stewardship are two of the best ways to help manatees. You can connect with these Florida ambassadors locally on a Wakulla Riverboat Tour at the State Parkor through outfitters that provide kayaks and local guiding knowledge. Simple changes in home practices that protect water quality also protect the water resources used by manatees and other wildlife. Observing manatee protection zones and reducing boat speedalso have been shown to reduce the impact of boating activities on manatees. To report sick or dead manatees, please call the FWC Wildlife Alert Hotline at 888-404-FWCC (3922).

This past October, the Florida Fish and Wildlife Conservation Commission held the first state lionfish summit in Cocoa Beach. Researchers, fishery managers, divers, fishermen, and the general public received research updates, discussed current issues, and provided input regarding future management needs. Here are a few of the interesting highlights from the summit.

What are the potential problems?
Several theories on how lionfish were initial released into state waters have been suggested. However, research results now indicate a single introduction of lionfish in Florida initiated the invasion into the Western Atlantic presumably from just a few aquarium specimens.
Sixty-thousand lionfish continue to be imported into the state each year.
Compared to native Pacific population, Florida densities of lionfish are much higher; 400 fish/hectare in Florida compared to 80 fish/hectare in the Pacific. On average, invasive Atlantic Lionfish individuals are larger than the native populations in the Pacific basin.
Studies from Pensacola showed that lionfish population has doubled annually since 2010 and lionfish densities are highest on artificial reefs.
Invasive lionfish have no natural predators and may spawn 30,000 – 40,000 eggs every 2 to 4 days.
Another potential problem reported are records of lionfish entering the Loxahatchee and Indian Rivers; indicating that they are able to move into brackish water.
What are the negative impacts?
Young lionfish feed primarily on crustaceans and when they are older they prey on reef fish. Research and stomach analysis indicate 70 different reef fish species as potential prey. Lobster fishermen in the Keys found lionfish are the leading by-catch species and have reduced lobster harvest by as much as 50%. Another study indicates lionfish on natural reefs they prefer blennies. However, on artificial reefs they feed on small snappers, sea bass, and groupers. Finally, an interesting study compared primary reef predators. Reefs with only grouper there was a 36% decrease of juvenile fish while reefs with lionfish the decrease was 94%.
What can be done?
Several reports indicate that collecting tournaments are effective; Lad Akins of Reef Environmental Education Foundation (www.reef.org) reported a 69% reduction of lionfish from one event in Key Largo. Another study had similar results but indicated that some spear fishermen were more successful than others, suggesting training may be required to increase efficiency.
Other reports indicate that work where native fish were introduced and conditioned to consume lionfish have led these native predators to follow and even bite divers thinking that “free food” may be available; it was suggested that this idea not be pursued.
Locally, lionfish rodeos sponsored by Emerald Coast Reef Association occur frequently in Okaloosa County. Escambia County Marine Resources hosted a pilot event this summer. Escambia will begin a full lionfish control program in 2014. If you have questions or comments, please contact your local UF/IFAS natural resource or Sea Grant Extension Agent.
Please note: UF/IFAS and Florida Sea Grant does not organize volunteers to participate in local lionfish control events; this is done by independent community groups.

“Imitation is the sincerest of flattery,” wrote Charles Caleb Colton. Colton was a sometimes cleric, essayist, wine merchant and gambler who bounced around Europe and North America during the early nineteenth century. It is likely many of his financial lenders hoped the public would not imitate his borrowing practices.
Aside from his few literary works and the catchy phrase above, he was most noted for running up debts then leaving for parts unknown.

Imitations are not looked upon kindly when lazy students, or journalists for that matter, complete an assignment by borrowing blocks of text. Plagiarism is a flunking and firing offense with career-ending potential.
The concepts of imitation and mimicry date back to the earliest written records of ancient Greece. The philosopher Plato used mimicry to define beauty and truth, and as a contrast to the negative aspects of life.
For the denizens of north Florida’s untamed regions, mimicry is a form of imitation which assures the survival of some. Survival always beats the alternative.
Insects are particularly effective at using several forms of mimicry to survive and reproduce in a very hostile environment where big hungry creatures always are on the prowl for their next meal. Eyes and disguise are the top tactics for continuation of the species. Multiple eyes on the bug’s face are common in the insect world. Large, eye-like spots on the rear of the bug are an effective form of defensive mimicry used by several local caterpillars species.
The saddleback caterpillar is a good example of how this deception is carried. There are two color-coordinated eye-like spots on the rump of this caterpillar. These spots are exponentially larger than the saddleback’s real eyes, which are barely visible without the aid of magnification. An approaching predator will quickly notice the blankly staring spots and likely recall the last encounter with this appropriately named creature.

It is worth noting the saddleback caterpillar has more defensive weapons systems than an Ageis missile cruiser. The novice predator that attempts to dine on this colorful, plump morsel will always remember the experience.
In addition to insects and caterpillars, some spiders have eye-spots on their thorax. Depending on the circumstances, the hunter can easily become the hunted.

Another mimicry tactic is camouflage, the ability to blend into the background and avoid detection. Millions, if not billions, of dollars of hunting clothing is sold annually to provide deer and turkey hunters that perceived advantage over their potential trophy animal. Moths are quite adept at using this technique to hide in plain sight. In the wild they almost always rest or lay eggs on surfaces which closely resemble their color scheme.
The last form of mimicry occasionally seen is the lure. This method attracts the prey to its demise. A prime example is employed by young water moccasins which have a sulfur-yellow tipped tail. The tail is shaken to resemble a wounded insect as the snake hides in the leaf litter. The unwitting victim is surprised, no doubt, to discover its status as a menu item.
