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?
Orchid mantises tend to be advantaged in habitats that remain constant; the rain forest habitat is likely to shift because of global climate change. While the tropical cockroach is a more hardy species, the optimum habitat for orchid mantises is one with limited variation in temperature, moisture, and humidity
Members of an r-selected species have what characteristics?
They are small species with many offspring, minimal parental care, early maturation, short life span, usually reproduce once, and low habitat competition.
The spotted lanternfly is a herbivorous insect that is native to Asia and feeds on over 70 species of plants. The feeding behavior of the spotted lanternfly damages plants and the nymph and adult lanternflies secrete sticky residues that exacerbate the damage to native plant species by promoting mold growth. The spotted lanternfly 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 lanternfly 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?
R-strategists because they only reproduce once, and it is many offspring.
The K-selection reproductive strategy maximizes survival of offspring by producing what?
They produce few offspring, but they have high parental care.
What is generally true of K-strategist species as compared to r-strategist species?
K-strategists have longer life spans, produce fewer offspring (but reproduce multiple times), provide high parental care to offspring, and thrive in stable environments.
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?
Raccoons are generalists, and salamanders are specialists. Generalist animals feed on a wide variety of prey or food that they might find anywhere. They can develop under many environmental conditions making use of many resources. Specialist animals search for their special kind of prey or food until they find it, inhabiting only in areas under certain conditions.
Based on the data in the graph, what best identifies the reproductive strategy of harbor seals?
They are likely K-strategists because they are reaching their carrying capacity.
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?
Based on this description, the cycads are K-strategists with a Type I survivorship curve. K-selected species are species that have a low growth rate that leads the population to increase slowly until it reaches its carrying capacity. Type I survivorship curve is a type of survivorship curve whose rate of survival is high. The individuals here often start to die in large numbers as they approach old age.
The Venus flytrap is a carnivorous plant that grows best in nutrient-poor, acidic soil. They typically grow in certain longleaf pine savanna ecosystems in the Carolinas. Generalist or specialist? Why?
A specialist species, because it thrives only in soils with low pH and nutrient levels.
Cycads are gymnosperms that were diverse and abundant during the Mesozoic era. Extant species of cycads share many traits with those from the Mesozoic era. Cycads bear cones, are long-lived with slow growth rates, show late reproductive maturity, and have very few offspring. Based on this description, the cycads are...
The cycads are K-strategists with a Type I survivorship curve.
