Document Summary
Vultures were dying from kidney failure in a short amount of time: they feed on dead carcasses, if the vultures are gone you get an increase in the number of infectious diseases. A lot of cattle got fed antibiotics, and the the vultures ate the cattle those antibiotics killed them. Population ecology has an impact on human society: impact population size, range, density, dispersion, generation time. Density tells you this, not range, since range just assumes that you will live wherever there is space, and not where there is recourses. How do we measure populations: direct count: count all the species you see (good for big animals). This can be hard because you can end up counting an animal more than once. You can use lures to attract certain animals. You can trap animals with captures to capture all of them. People use proxy measures sometimes, where you look for animal scat.
