Summary Introduction
Introduction:
An extinction event also called biotic crisis or mass extinction refers to a rapid and widespread reduction in Earth’s biodiversity. Such kind of incidents is determined by a sharp variation in the abundance and diversity of the multicellular organisms.

Which of the following is probably NOT an example of an exploitative relationship?
One species eating another species
One species completing its life cycle in or on a host
Two species utilizing the same resource
Scientists studying kingfisher birds in the South Pacific discovered that there are three subspecies that live
on the mainland of Papua New Guinea. These three subspecies can interbreed and are nearly
indistinguishable from one another. The kingfishers are found in a variety of environments on the mainland,
including rain forest and forests that have extended dry seasons.
However, on smaller islands not far from the mainland, many more species of kingfishers exist, and each
species is considerably different from one another. The environment on these smaller islands is very similar
to that on the mainland.
Which model is an accurate representation of the evolution of kingfishers in the South Pacific, and which
piece of evidence best supports this model? Use the drop-down menus to complete your answer.

Group of answer choices Extinction and extirpation are the same thing. Extirpation is the loss of a single population, while extinction is the loss of an entire species. Extinction only happens during a mass extinction.

- Which of the following is not a part of the red list criteria for "critically endangered" species? The population is expected to decline by 25% or more within 3 years or 1 generation. The species has a restricted range <100km2 at a single location and there is observed or predictive habitat loss, fragmentation, ecological imbalance or heavy commercial pollution. Extinction probably is greater than 50% within 10 years or 3 generations. The total population size is less than 200 mature individuals.arrow_forwardBiodiversity is described as: The seasonal and daily changes in an environment The range of different species in an environment The influence of physical factors on an environment The way species differ from one anotherarrow_forwardCA least tern ENDANGERED ANIMAL is CA least tern questionbases on the bird CA least term Reasons for Endangerment Explain the various factors that have led to this species’ current plight.

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. How is the absence of this species (or its lowered population size) likely to impact the other members of its habitat? (If findings specific to this point are available, please include them – otherwise, I’m asking you to speculate based on what you’ve learned about the biology of this organism.) Conservation Efforts Discuss past, current, and proposed efforts to conserve this species. Are these strategies effective? Are they realistic? What is the outlook for this organism?arrow_forward
