One core goal of ecology is to understand the distribution and abundance of living things in the physical environment. Attainment of this goal requires the integration of scientific disciplines inside and outside of biology, such as biochemistry, physiology, evolution, biodiversity, molecular biology, geology, and climatology.

Population ecologists study what determines the occurrence and abundance of species in space and time: their geographic ranges, population sizes and densities, what factors result in them being so rare or common, and why these characteristics change over time.

A core goal of ecology is to understand the distribution and abundance of organisms in the environment. This requires integrating many scientific disciplines, such as biochemistry, physiology, evolution, biodiversity, molecular biology, geology, and climatology. Some ecological research also applies aspects of chemistry and physics, and it and it frequently uses mathematical models.

Their numbers fluctuate based on a number of abiotic and biotic factors. The primary focus of community ecology is on the interactions between populations as determined by specific genotypic and phenotypic characteristics.

Note that in the former, the effect of the factor on the population depends on the density of the population at onset.

Population ecologists are often tasked with determining if populations are increasing, stable, or declining. More complex patterns are also possible, such as rebounds after sharp declines or regular cycles. To understand what determines what a population does over time ecologists think about processes of population regulation -
