Dispersion in time and space affect mating success and Allee effects in invading gypsy moth populations.
1. Understanding why invading populations sometimes fail to establish is of considerable relevance to the development of strategies for managing biological invasions. 2. Newly arriving populations tend to be sparse and are often influenced by Allee effects. Mating failure is a typical cause of Allee effects in low-density insect populations, and dispersion of individuals in space and time can e...
متن کاملAllee effects, adaptive evolution, and invasion success
The mechanisms that facilitate success of an invasive species include both ecological and evolutionary processes. Investigating the evolutionary dynamics of founder populations can enhance our understanding of patterns of invasiveness and provide insight into management strategies for controlling further establishment of introduced populations. Our aim is to analyze the evolutionary consequence...
متن کاملGenetic variation and mating success in managed american plains bison.
The American plains bison (Bison bison) was pushed to the brink of extinction in the late 1800s but has since rebounded. Less than 5% of animals currently exist in conservation herds that are critical for maintaining genetic variability. Here, we use 25 microsatellite loci to assess genetic diversity and patterns of mating success over a 3-year period in a managed conservation herd at Konza Pra...
متن کاملORIGINAL ARTICLE: Allee effects, adaptive evolution, and invasion success
While advances in free trade and globalization increase the movement and accelerate the accumulation of invasive species (Lockwood et al. 2005), it is still unclear how introduced populations can successfully establish. As Elton (1958) pointed out, for every successful invasion that occurs, ‘there are enormously more invasions that never happen, or fail quite soon or even after a good many year...
متن کاملAccounting for Variation in Mortality and Allee Effects When
13 We update recent work on the scientific inference and reproductive biology of steepness in three 14 directions. First, we show how variation in natural mortality can be included in the formula 15 for steepness, for both a biomass dynamics and age-structure models. We do this using the 16 delta-method, so that only the mean and covariance of natural mortality rates appear in the 17 characteri...
