What Is Logistic Growth? Quick Answer. Logistic growth is when the growth rate of a population decreases as the number of its members increases. It occurs when an environment has limited resources. Population expansion decreases as resources become scarce and levels off when the environment?s ability to support the population is reached.

Logistic function More quantitatively, as can be seen from the analytical solution, the logistic curve shows early exponential growth for negative argument, which slows to linear growth of slope 1/4 for an argument near 0, then approaches 1 with an exponentially decaying gap.

apex When there's no mountain left to climb and nothing but blue sky above, you know you've reached the highest peak — the apex. Apex can mean the highest point in a literal sense, like climbing to the apex of the Eiffel Tower for a fabulous view of Paris. It also can be used to mean the highest point in a figurative sense. An actor who wins an Oscar can say she's reached the apex of her career. If you're describing more than one high point, you could add an -es to form the plural apexes, but apices would also be correct.

exponential growth exponential growth. Increase in number or size, at a constantly growing rate. It is one possible result of a reinforcing feedback loop that makes a population or system grow (escalate) by increasingly higher amounts. Compound interest is an example of exponential growth.

Logistic function A logistic function or logistic curve is a common S shape (sigmoid curve), with equation: where e = the natural logarithm base (also known as Euler's number), x 0 = the x-value of the sigmoid's midpoint,L = the curve's maximum value, and.he logistic function is the inverse of the natural logit function and so can be used to convert the logarithm of odds into a probability. In mathematicaly notation the logistic function is sometimes written as expit in the same form as logit.

POPULATION ECOLOGY Most populations have the potential to expand at an exponential rate, since reproduction is generally a multiplicative process. Two of the most basic factors that affect the rate of population growth are the birth rate, and the death rate. The intrinsic rate of increase is the birth rate minus the death rate. Two modes of population growth. The Exponential curve (also known as a J-curve) occurs when there is no limit to population size. The Logistic curve (also known as an S-curve) shows the effect of a limiting factor (in this case the carrying capacity of the environment).

Chapter 19 . Population and Community Ecology When the population size is equal to the carrying capacity, or N = K, the quantity in brackets is equal to zero and growth is equal to zero. A graph of this equation (logistic growth) yields the S-shaped curve (Figure 19.5b). It is a more realistic model of population growth than exponential growth.

Exponential growth Exponential growth (including exponential decay) occurs when the growth rate of a mathematical function is proportional to the function's current value. In the case of a discr … ete domain of definition with equal intervals it is also called geometric growth or geometric decay (the function values form a geometric progression). Exponential growth is said to follow an exponential law; the simple-exponential growth model is known as the Malthusian growth model. For any exponentially growing quantity, the larger the quantity gets, the faster it grows. An alternative saying is 'The rate of growth is directly proportional to the present size'.

Logistic regression Logistic regression. Description. Logistic regression is a statistical method for analyzing a dataset in which there are one or more independent variables that determine an outcome. The outcome is measured with a dichotomous variable (in which there are only two possible outcomes).

Apex predator An apex predator, also known as an alpha predator or apical predator, is a predator residing at the top of a food chain upon which no other creatures prey. Apex predators are usually defined in terms of trophic dynamics, meaning that apex-predator species occupy the highest trophic level or levels and play a crucial role in maintaining the health of their ecosystems. One study of marine food webs defined apex predators as greater than trophic level four.

Translations for logistic function Wiktionary (0.00 / 0 votes) Rate this definition: logistic function (Noun). A function, the result of the division of two exponential functions, that gives rise to the logistic curve.or values of t in the range of real numbers from −∞ to +∞, the S-curve shown is obtained. In practice, due to the nature of the exponential function e−, it is often sufficient to compute t over a small range of real numbers such as [−6, +6].

EXPONENTIAL FUNCTIONS All exponential functions have the form ax, where a is the base. Therefore, to say that the rate of growth is proportional to its size, is to say that the derivative of ax is proportional to ax. where k is the constant of proportionality.
