The International Union for the Conservation of Nature and Natural Resources (IUCN), has declared 418 animal species in the Philippines to threatened: meaning they are either vulnerable, endangered, or critically endangered. What small steps that you can do to save these animals?
Approximately 14,000 years ago, the climate in North America began to warm rapidly. At the same time, human hunters migrated to the continent. Which of these most likely resulted from a combination of these two factors? an increase in the rate of large mammal extinctions
a reduction in the rate of species change
an increase in the amount of interspecies cooperation
a reduction in the total number of small parasitic insects
Fully one-third of all amphibian species are threatened with extinction, and more than 40% have undergone significant population declines over the past decade (Fig. 49.24). What accounts for this pattern?

Which characteristics make species more vulnerable to extinction? species that have a generalized diet species that have a small population size species that are not negatively affected by introduced species species that are used by humans for food and clothing species that have a long life spanarrow_forwardThe following picture represents mussels, goose barnacles, sea stars, anemones, etc. competing over space. Gary Luhm/Danita Delmont Stock Photography If the species ended up in each location by chance and are using up space without direct interactions, this would be an example of competition. If the species are actively competing with one another over who gets to live in which location (uplifting/crushing), this would be an example of competition. Act Go toarrow_forward
- A niche is loosely defined as an organism's role in its environment, which can include factors such as feeding preference, nesting behaviors, mating behaviors, method of obtaining prey, and local habitats. Keeping Gause's law in mind, do some research on the California red-legged frog and the North Pacific tree frog (use wiki or another Google search). Create a chart comparing the two with respect to their niche or lifestyle that can explain how these two frogs can co-exist in the same ecosystem.arrow_forwardWhat are some potential solutions to decrease the threat/endangerment of sea turtles? What can humans do? What are some solutions that scientist or convervationist tried to do to help sea turtles? What is one hypothesis on further environmental, ecological, biodiversity or other biological problems that this solution might intentionally or unintentionally create?arrow_forwardChoose all incorrect statement. In 2021, 23 species were declared extinct. Most of these have been presumed to be extinct for decades. Eight of the declared extinctions were bird species endemic to the Hawaiian Islands. One species declared extinct was the Molokai creeper (pictured). Main causes of their extinction include loss of suitable habitat, disease, and predation by introduced mongooses and rats. Avian malaria is transmitted between bird species in Hawaii by mosquitoes that were brought to the islands by ships many decades ago. Which of the following statements is NOT accurate? a.Avian malaria is a vector-borne disease; if it infects 90% of the birds regardless of bird population size, it is acting as a density-independent factor. b.Among vertebrates, bird population sizes have declined the most compared to any other vertebrate group. c.Eliminating invasive rats and mongooses from the Hawaiian Islands, like goats were eliminated from the Galapagos, could help prevent further…arrow_forward
- Why are frogs a good indicator species? They are increasing in number, suggesting that they are resistant to environmental degradation. They are resistant to increases in ultraviolet light. They are of considerable economic importance. Their numbers can be manipulated easily with minimal effects on other species. Their eggs do not have hard shells to protect them from environmental contaminants.arrow_forwardCan you answer all the parts to this question Anadromous- born in freshwater, migrate to saltwaterCatadromous- born in saltwater, migrate to freshwaterOceanodromous- born in saltwater body, migrate to another saltwater bodyPotamodromous- born in freshwater stream or lake, migrate to another stream or lake Example of one anadromous species?

This event contributed to the original influx quantities of pythons in the wild. Pet owners also contributed to the introduction of these reptiles to the Everglades by releasing pets that had grown too large to care for. These reptiles are considered species to this ecosystem. can someone please write an explanation that describes the impact of the Burmese python on the Everglades?

- The ENDANGERED ANIMAL is CA least tern and its a bird 1. Species Description Visual description, size, reproduction, lifespan, unique behaviors 2. Habitat Needs & Ecological Roles What type of habitat does it require? What does it eat? Who eats it? What role does this species play in its biological community?, etc. 3. Geographic Range/ Population Status Where is this species found geographically? How does its current range compare with where it’s distributed today? How many of these organisms are present in our region? (Or – if you can’t find overall numbers, is there data available on specific populations of this plant/animal?) 4. Reasons for Endangerment Explain the various factors that have led to this species’ current plight. Expand on these points individually, based on your species’ unique story. 5. Domino Effects As we’ve learned, species are not islands unto themselves; they are integrated with many other organisms in trophic relationships, mutualisms, competition, etc.…arrow_forwardWhich of the following is a conclusion drawn by the authors from the results of this study? Temperate marine invertebrate species are outcompeting endemic species which will soon become extinct in the surveyed areas. Tropical marine invertebrate species did replace temperate species from 1982 to 2021 in the surveyed areas. Tropical marine invertebrate species did not replace temperate species from 1982 to 2021 in the surveyed areas. The temperate marine invertebrate species density and richness will recover with sufficient monitoring and resources.

The carrying capacity of seals would decrease, as would the seal population. b. The carrying capacity of seals would decrease, but the seal population would remain the same. c. The number of seal deaths would increase, but the number of births would also increase, so the population size would remain the same. d. The carrying capacity of seals would remain the same, but the population of seals would decrease.arrow_forward
