Spatial dynamics in fluctuating vole populations

Oecologia, 1990
Patterns and consistency of distribution, spatial and temporal components, and the extent of spatial density-dependence were compared between semi-cyclic and cyclic populations of the vole species Clethrionomys glareolus and Microtus agrestis in south-central and north Sweden. Cyclic populations were less clumped and only C.

Spatial and temporal variability in a butterfly population

Oecologia, 1991
The dynamics of a butterfly (Plebejus argus) population were analysed at two levels, (i) the population as a whole and (ii) sections within the population. Some sections of the population fluctuated out of synchrony with others, such that the variability [SD Log(Density+1)] shown by the population as a whole was less than the variability shown by each ...

A spatial approach to insect population dynamics

Nature, 1976
THERE are two aspects of the regulation of animal numbers: first, how the numbers in a population are controlled around a mean level over a number of generations and second, how this mean level is determined. Studies on the dynamics of insect populations leading to the construction of life tables are frequently confined to a particular location where ...

Spatial Mismatch, Poverty, and Vulnerable Populations

2013
Spatial mismatch relates the unemployment and poverty of vulnerable population groups to their remoteness from job opportunities. Although the intuition initially applied to African Americans in US inner cities, spatial mismatch has a broader validity beyond the sole US context.

Cooperative Dynamics in Spatially Structured Populations

2008
The evolution of cooperative behaviors of small-world networking agents in a snowdrift game mode is investigated, where two agents (nodes) are connected with probability depending on their spatial Euclidean lattice distance in the power-law form controlled by an exponent i¾?.
