3.1-3.2 Generalist & Specialist, K & r-select

the orchids are specialists and the cockroaches are generalist species

The orchid mantis that is highly camouflaged when standing on a certain species of orchid found in tropical environments. Another species, the tropical cockroach, can live anywhere in the rain forest where it can find water and a food source. What best describes why it is predicted that the orchid mantis will be more affected by global climate change than the tropical cockroach will be?

r-selected species tend to live by their reproductive capacity

They don’t abide by resources and try to have as much offspring as possible (BIOTIC POTENTIAL)

Small in size, short life expectancy, many offspring

Members of an r-selected species have what characteristics?

R-select and invasive species

The spotted lantern fly is a herbivorous insect that is native to Asia and feeds on over 70 species of plants.The feeding behavior of the spotted lantern fly damages plants, and the nymph and adult lantern flies secrete sticky residues that exacerbate the damage to native plant species by promoting mold growth. The spotted lantern fly reproduces once during its lifetime by laying between 30 and 50 eggs, and the eggs hatch after a short amount of time. The range of the spotted lantern fly is increasing because the insects are transported to new environments by the movements of animals and people, and it is now found in many parts of the United States.What kind of strategist is this?

Few offspring with high levels of parental care

The K-selection reproductive strategy maximizes survival of offspring by producing what?

They have longer life spans

What is generally true of K-strategist species as compared to r-strategist species?

Raccoons are generalists, and salamanders are specialists

Raccoons eat a variety of foods and can live in a variety of habitats, including locations near humans. Tiger salamanders eat an abundance of worms and insects and require wetland habitats so they do not dry out. Are they generalist or specialist species ?

K-species

Based on the data in the graph, what best identifies the reproductive strategy of harbor seals?

Salamanders, only eat insects and can only live in small freshwater pools

Salamanders, ospreys, snapping turtles, and beavers all live in aquatic habitats. Salamanders lay their eggs in small freshwater pools and feed on insects. Osprey habitats include rivers, bays, and swamps and the birds feed on fish and other animals in the water or on land. Snapping turtles live in fresh or brackish water and feed on plants, fish, frogs, and snakes. Beavers build lodges on islands, pond banks, and lake shores and eat a variety of shrubs, grasses, and crops.Based on the information provided, what species would best be classified as a specialist?

A specialist species, because it thrives only in soils with low pH and nutrient levels.

The Venus flytrap is a carnivorous plant that grows best in nutrient-poor, acidic soil. They typically grow in certain long leaf pine savanna ecosystems in the Carolinas. Generalist or specialist? Why?

Racoons, Bobcats, Coyotes, mice and rats

What are examples of generalist species

generalist

Do generalist or specialist species become invasive?

specialist

Do generalist or specialist species become endangered?

Koalas - Eucalyptus tree
Canada Lynx - snowshoe hare
Pandas - bamboo

What are examples of specialist species

K-select

Which one takes more time to Devote energy, and time to parental care!!!
