Traits- The wood frog is a small to medium size frog with the colors being brown, tan, rust, and green. They are ectodermic organisms with moist skin. They can freeze themselves for winter by producing antifreeze-like substance.

Life cycle- They are oviparous so they start as an egg and they are externally fertilized and go through complete metamorphosis.They're eggs for about 20 days then hatch into tadpoles are in that stage for about 80-115 days. The males become sexually mature after 1-2 years and females are mature after 2-3 years.

Habitat- They live in aquatic or semi-aquatic ecosystems and are found in the wetland interior and areas of Alaska. Wood frogs can be found specifically in wonder lake and reflection pond in Denali national park.

Food web- Wood frogs are carnivores as adult preying on floor invertebrates and insects which also mean they help control the insect population but, as tadpoles they only eat plant matter and algae. They are prey for birds and mammals like for trumpeter swans, horned Grebe, and bobcats

Traits- The horned Grebe has a black bill with a white tip, yellow patches on the side of there heads which gives them the horn look, reddish colored neck and bottom side, and they have a scaly gray back. They have red eyes and hollow bone and they are also precocial meaning they can swim as soon after they hatch.

Life cycle- They are oviparous and they are incubated for 22-25 days until they hatch then stay with their parents until around 20-25 days where they become independent. They can't fly until after 41-50 days and become sexually mature after 1 year and live to at least 5 years.

Habitat- The Horned Grebe lives in a freshwater ecosystem and can be found in lakes and ponds specifically Reflection pond and Wonder lake in Denali national park.

Food web- Firstly the Horned Grebe can eat their own feathers which forms a plug in their stomach to hold bones until they fully digestion.

Traits- The white Tail Bumble bee gets its name from its bright white tail, two yellow bands on its body, and a general black coloration. It has a short tongue to forage on open flowers. Queens are typically 19-20 mm long, males are 14-16 mm, and workers range from 11-17 mm. 

Lifecycle- They go through complete metamorphosis they hatch as a larva and go into a pupa for about 2 weeks and hatch into a bee but they take a day to harden. They are sexually mature after 3-4 weeks after they emerge from the pupa.

Habitat- White Tail Bumble bees aren't limited to one type of ecosystem they primary around any kind of plants, trees, flowers, etc. Specifically in Denali national park high-elevation alpine areas

Foodweb- They eat mainly nectar and pollen from plants and flowers so they are classified as herbivores. In the national park they are preyed upon by birds, mammals, and spiders

Traits- They are typically brown or dark brown, with males having larger bodies and antlers and females not having antlers. They can stand up to almost 6 feet tall at the shoulder. Moose have a large dewlap of skin hanging down from their jaw which looks like a beard. They have acute senses of smell and hearing and have incredible endurance and speed. Since they are mammals they are also Endothermic.

Life cycle- The Alaskan Moose is viviparous and a placental with a gestational period of about 8 months. They give live birth and the calf stays with its mother for 1 so she can breed for another calf. Both male and female moose reach their sexual maturity peak around 4-5 years. They can live between 10-20 years in the wild.

Habitat- The Alaskan Moose belongs to the boreal and tundra ecosystem and can typically be found in the northern forest specifically between the park entrance and Savage River.

Food web- The Alaskan Moose is a herbivore that eats forbs, grasses, sedge, and leaves in the summer, and shift to woody browse like willow, aspen, poplar, and birch twigs in the fall and winter. They can be prey for wolves, grizzly bears, and cougars but due to their size and antlers they can defend themselves.

Traits-The arctic Grayling has large, sail-like dorsal fin, colorful markings, and iridescent scales. They are also known for their ability to migrate long distances, reaching maturity quickly, and thriving in cold, clear waters. They're typically between 12-20 inches long, they have jaws and they are ectothermic.

Life cycle- The arctic grayling is oviparous and they fertilize the eggs in a process called broadcast spawning where the water moves the sperm to the eggs. They are eggs for about 2-3 weeks and then hatch into juveniles then they reach maturity after 3-4 years.

Habitat- They live in cold freshwater ecosystems and can be found in various rivers and streams. Specifically, the Nenana River, Clear-water Creek, Canyon Creek, and Seattle Creek, all draining into the Nenana. Also areas along the Denali Highway, such as Fish Creek and Brushkana Creek.

Food web- The arctic grayling is both predator and prey. They prey on insects, fish's, and small animals they are carnivores . In Denali national park they are preyed on by birds like dippers, mergansers, goldeneyes, and kingfishers
