by K Sigmund · 1998 · Cited by 37 — Population ecology If we assume that n species live in an ecosystem, that xi is the density of species i and that its per capita growth rate _xi=xi depends ...
Population ecology is a branch of ecology that explores the intricate relationships between organisms of the same species living in a particular area.
The primary goal of this section is to understand the processes that cause changes in population size through time. A second goal is to understand simple ...
The best way to develop intuition about population dynamics is to study simple mathematical models. Let us consider, then, the dynamics of simple models of ...
Using concepts from basic population biology, biologists have distinguished two strategies for population growth. Some species have characteristics that allow ...
Another use of population models is to conceptualize the dynamics of a population in a rigorous mathematical notation. Such a conceptual model allows biologists ...
In this course, students will learn the theory and application of quantitative methods to estimate popula- tion level statistics and quantify ...
by M COLYVAN · 2003 · Cited by 32 — Abstract. The standard mathematical models in population ecology assume that a population's growth rate is a function of its environment.
Additive Mortality: A cause of mortality that when changed in magnitude results in a relatively equivalent and opposite change in overall survival.
One is population and evolutionary genetics, whose problematic is the rate and direction of genetic change within populations and the genetic di- vergence ...

Every time you take a breath, the world's human population grows by 20 people. Human per-capita population growth rate is now about 1.7% per year. (r = 0.017).
In solving ecological problems we are concerned with what animals do in their capacity as whole, living animals, not as dead animals or as a series of parts ...
Such a framework has the potential to help address the 'serious disconnections between the quantitative nature of ecology, the quantitative skills we expect of ...
The main focus of this course will be: 1. Estimation of population parameters (e.g., survival, movement, breeding probability) using multi-state and multi-event ...
Political policies, economic decisions, cultural beliefs that support population growth. • Demographic transition model, referring to Stage 2 and/or early Stage ...
