The wormsorter facilitates genetic screens in Caenorhabditis elegans by sorting worms according to expression of fluorescent reporters. Here, we describe a new usage: sorting according to colonization by a GFP-expressing pathogen, and we employ it to examine the poorly understood role of pathogen recognition in initiating immune responses.

FAQs
Colonization rate reflects more than the presence of arriving individuals or microbial propagules. Arrival supplies potential colonists, but establishment depends on whether they survive local conditions and reproduce or grow afterward. A habitat may therefore receive many arrivals yet show limited colonization when survival is poor, while favorable conditions can support rapid establishment from relatively few successful colonists.
Habitat suitability, resource availability, and interactions with other organisms strongly influence the outcome. Suitable conditions and sufficient resources can support survival, growth, and reproduction, increasing colonization rate. Competition can reduce access to resources or limit establishment, slowing biological spread. These factors help explain why the same species or microbial population may establish differently across habitats.
Dispersal or arrival describes the movement of individuals or propagules into a habitat, whereas colonization rate also reflects what happens after arrival. Survival under local conditions and subsequent reproduction or growth determine whether newcomers establish. This distinction allows researchers to separate limitations in reaching a site from limitations caused by unsuitable habitat or biological interactions.
Tracking colonization rate helps show how populations become established and how biological communities develop over time. Differences among species can indicate contrasting dispersal strategies, environmental tolerances, or abilities to compete for available resources. In this way, the measure connects population distribution with the processes that shape ecosystem development rather than treating community composition as a static outcome.
Researchers can compare colonization rate across habitats by examining how quickly species or microbial populations become established under different environmental conditions. Such comparisons help identify the effects of habitat suitability, resource availability, and competition. They can also be used to evaluate whether a recovering habitat is progressing toward renewed biological development or remains difficult for organisms to occupy.
In ecology, colonization rate helps researchers evaluate habitat recovery and monitor invasive species. In microbiology, it supports comparisons of how microbial populations establish in previously unoccupied settings. Disease biology uses the same concept to examine biological spread and establishment. Across these fields, the measure helps assess responses to environmental change and clarify population distribution.
