Ronce and Promislow 2010
Not quite related to population patterns, but it deals with our discussion last week (evolution of fecundity, senescence, etc.). Further, I find it very thought provoking and will hopefully contribute to our working understanding of dispersal.

DISPERSAL DEFINITIONS FROM 18 FEBRUARY 2011
Chris: “Q: What is dispersal? A: Population interaction.
There are two types of dispersal: ecological and genetic dispersal. Genetic dispersal is always ecological dispersal, but ecological dispersal is not always genetic dispersal.
Both ecological and genetic dispersal should be examined at the level of the population.
Ecological dispersal is tantamount to migration. Once an individual has left its population, there is one less individual and changes population dynamics (e.g., recourse allocation). Consequently, an immigrant changes its new population dynamics (e.g., it “took’r jybs”).
Genetic dispersal is tantamount to gene flow. Once an individual has left its population, there is one less individual and changes the population genetic composition and structure. Notice that emigration in genetic dispersal does effect the population, as it reduces the population size and is not longer a potential contributor to that gene pool. Consequently, an immigrant—one that contributes its genes to the new population (e.g., “Anchor Baby”)—changes the population genetic composition and structure.
These definitions are highly contingent upon the definition of a population. I think that much of the confusion actually deals with the definition of a population. Likewise to dispersal, I think that populations can be viewed as ecological and genetic and ideas about dispersal are relative to the population relation to other populations and the environment.”
Chad: “My simple definition of dispersal: movement that results or may result in fitness gain.”
Mandy: “Movement away from one population and into another.”
Nova: “. . . movement of an individual away from an existing population or away from the parent organism in which the consequences create changes in species distribution, population dynamics, population genetics, or an individual's fitness.”
Matt:”I am interested in: Movement in space by individuals or propagules.
Consider example:
Some silly chipmunks in the Sierra. Imagine you have each one radiotagged within a pretty large area of continuous habitat, and you observe movement at roughly four scales... (1) most individuals move within a short radius around their dens; constant movement within this area. (2) occasionally an individual is seen to move on a wider trajectory, apparently crossing into the "home ranges" (if they are that) of other individuals, but returning to the area in #1. (3) even less frequently an individual moves to a peripheral area and starts activities like those in #1. (4) even less frequently (it happens once during your study) an individual takes off over the pass and is not heard from again.
So, the question: what explains movement at these different scales. Hypotheses:
#1 is foraging for food
#2 is stealing other individuals' food or looking for mates (not sure)
#3 is a juvenile looking for a place to set up shop
#4 who knows... maybe that individual is responding to packed conditions.... maybe that individual has a gene that says get the crap out of town and found a new colony....
Personally, I don't see anything to be gained by saying some of those are "dispersal" and some are not. They are patterns of movement in space, and we can ask questions about each one. Someone might be tempted to call only #4 dispersal, but beware that the distinction between #3 and #4 might be pretty fuzzy.....”
