Here’s a comprehensive description of the topics you've mentioned:
Breeding Seasons
-
Peak Breeding for Whitetail Deer: Peak breeding season (or "rut") for whitetail deer typically occurs from mid-October to early December, with variations depending on specific geographic locations and environmental cues.
-
Peak Breeding for Turkey: For wild turkeys, peak breeding season usually occurs in March and April, coinciding with their mating behaviors as males establish dominance and territories to attract females.
Decline in Bobwhite Quail Population
- Main Cause for Decline in Bobwhite Quail Population: The decline in the bobwhite quail population is primarily attributed to habitat loss due to urbanization, agricultural practices, and land management changes, which reduce nesting and brood-rearing habitats.
Migration Factors
- Migration Factors:
- Ducks: Factors include temperature, food availability, and water conditions. As temperatures drop and food becomes scarce in northern regions, ducks migrate south to more hospitable areas.
- Mourning Dove: Mourning doves migrate in response to food availability and weather conditions, typically moving south in the fall to seek seeds and warmer climates.
- Canadian Geese: Migration is influenced by photoperiod, weather, and food sources. They migrate in a V-formation, moving to areas with ample food and water for breeding and wintering.
- Snow Geese: They migrate based on the availability of food sources, especially during their spring migration when they seek out newly thawed agricultural fields to replenish energy.
Wind and Scent Cone
- Prevailing Winds and Swirling Winds Affecting Scent Cone: Prevailing winds can carry a scent cone downwind, allowing predators to scent prey from a distance. Swirling winds, on the other hand, can disrupt this scent cone, making it difficult for predators to track their prey accurately, which can impact hunting success.
Wetlands
-
How Wetlands Work: Wetlands act as natural water filtration systems, absorbing excess nutrients and sediments from runoff. They provide habitats for diverse species, facilitate groundwater recharge, and help regulate floodwaters.
-
Diversity of Wetland Ecosystems: Wetlands are among the most diverse ecosystems because they provide a unique interface between aquatic and terrestrial habitats. This diversity accommodates numerous plant and animal species, many of which are specially adapted to this environment.
Subspecies of Turkeys and Their Habitats
- Six Subspecies of Turkeys:
- Eastern Wild Turkey: Found in eastern U.S. forests and open woodlands.
- Rio Grande Wild Turkey: Inhabits the grasslands and river valleys of the southern Great Plains.
- Merriam's Wild Turkey: Prefers mountainous forested areas in the western U.S.
- Osceola Wild Turkey: Restricted to Florida’s wetlands and forests.
- Gould's Wild Turkey: Found in the mountainous areas of the southwestern U.S. and Mexico.
- Ocellated Turkey: Native to the Yucatán Peninsula, mostly inhabiting lowland tropical forests.
Plant Definitions
- Difference Between Mast, Legumes, and Forage:
- Mast: Refers to the fruit or nuts from trees (e.g., acorns, beechnuts) that are a crucial food source for wildlife.
- Legumes: Plants like clover and beans that are high in protein and nitrogen-fixing, providing both forage and improving soil quality.
- Forage: General term for edible plant material (grasses, leaves, etc.) consumed by grazing animals and wildlife.
Salmon Spawning
- Salmon Spawning: Salmon spawning occurs when fish return from the ocean to freshwater streams to lay eggs. Spawning involves finding suitable gravel beds, where females dig nests and deposit eggs while males fertilize them. After spawning, most salmon die, contributing nutrients to the ecosystem.
Predator Control
- Benefits of Predator Control: Effective predator control can help increase populations of game species by reducing predation pressures, allowing these populations to rebound and thrive, ultimately contributing to the overall balance of the ecosystem.
Hunting Pressure
- Effect of Hunting Pressure on Wildlife Movement: Increased hunting pressure can alter wildlife behavior, leading animals to change their movement patterns, become more nocturnal, or avoid areas with high human activity, impacting their feeding and breeding habits.
Upland and Wetland Game Species
- Upland Game Species:
- Ring-necked pheasant
- American woodcock
- Bobwhite quail
- Wetland Game Species:
- Mallard duck
- Wood duck
- Blue-winged teal
Native and Invasive Species
- Native Species Beneficial to Wildlife:
- Black oaks (provide mast)
- Native grasses (for nesting cover)
- Wild blueberries (food for birds and mammals)
- Invasive Species Beneficial to Wildlife:
- Multiflora rose (provides cover for small mammals)
- Japanese honeysuckle (berries for birds)
- Autumn olive (berries for birds, though invasive)
Feral Hogs
- Advantages and Disadvantages of Feral Hogs:
- Advantages: Can provide a food source for hunters; they help in seed dispersal.
- Disadvantages: They are highly destructive, competing with native species for resources and causing soil erosion and habitat destruction.
Native Predators of Tennessee
- Five Native Predators:
- Eastern coyote
- Red fox
- Bobcat
- Great horned owl
- Raccoon
Chronic Wasting Disease (CWD)
-
How CWD Affects Whitetail Deer: CWD is a neurological disease that affects deer, leading to symptoms like weight loss, lack of coordination, abnormal behavior, and ultimately death.
-
Transmission of CWD: CWD is transmitted through direct contact between deer or through contaminated environments (saliva, feces, urine) where prions release into the soil. The prions are resistant to degradation and can remain infectious for years.
Nesting Locations
- Nesting Locations:
- Wood Duck: Typically nests in tree cavities over water.
- Canadian Geese: Prefer grassy areas near bodies of water for nesting.
- Mallard Duck: Build nests on the ground in tall grass or brush near water.
- Wild Turkey: Often nest on the ground under dense bushes or overhanging foliage.
- Bobwhite Quail: Nest on the ground in dense cover like grasslands or thickets.
- Mourning Dove: Usually nest in trees or shrubs, often in the forks of branches.
Antler Growth
-
Effects of Antler Growth After Injury: An injury to a deer may disrupt normal antler growth, leading to deformities or asymmetric antlers depending on the severity and location of the injury.
-
How Antlers are Grown: Antlers grow from the pedicles, with the process involving the shedding and regrowing of tissue each year during the growing season, powered by increased levels of testosterone.
-
Nutrients Needed for Optimal Antler Growth: Key nutrients include protein (from forages and legumes), minerals (such as calcium and phosphorus), and vitamins.
Barometric Pressure
- How Barometric Pressure Affects Wildlife: Animals can sense changes in barometric pressure associated with weather fronts. High pressure often leads to stable, calm weather, while drops may signal storms, influencing wildlife behaviors like feeding and breeding.
Turkey Behavior
- Why Turkeys Move to Openings and Fields During Rain: Turkeys may move to openings and fields during rain as these areas might provide better visibility and easier access to foraging opportunities.
Chufa Consumption
- Part of the Chufa Plant Consumed by Turkeys: Turkeys primarily consume the tubers of the chufa plant, which are high in carbohydrates and provide essential nutrition.
Alternative to Chufa
- Weed That Can Replace Chufa: One such alternative is "Japanese millet," which can provide similar food sources for turkeys and other wildlife.
