Title: In question 3, you thought about how the logistic growth equation produces a sig Post by: colleen on Feb 3, 2012 In question 3, you thought about how the logistic growth equation produces a sigmoidal growth curve. Now, let’s think about nature. What is it about the natural environment that produces sigmoidal growth? Pick a real organism living in an environment with which you are familiar and list the things that might limit the growth of its population.
Title: Re: In question 3, you thought about how the logistic growth equation produces a sig Post by: bio_man on Feb 16, 2012 Aspects of the environment that restrict birth rates in populations will limit population growth, producing a sigmoidal curve. These include factors such as limited habitat, food availability, predation, disease, parasites, and so forth. For example, arctic foxes are restricted to northern habitats by competition with southern red foxes, use prey species with cyclical population abundance, carry rabies and canine distemper, and can be preyed upon by larger carnivores.
