“…A notable example is the impact of the invasion of the brown tree snake, Boiga irregularis, into the snake-free forests of Guam after World War II. The introduction of this invasive species which occurred through the transportation of military equipment (Fritts and Rodda, 1995;Pimentel et al, 2005), precipitated the extinction of 10 native forest birds (Rodda et al, 1997). The so-called red swamp crayfish, Procambarus clarkii, which is included on several invasive species black lists is a good example of an invasion that precipitates positive and negative ecological impacts.…”

Biological invasions entail massive biodiversity losses and tremendous economic impacts that justify significant management efforts. Because the funds available to control biological invasions are limited, there is a need to identify priority species. This paper first review current invasive species prioritization methods and explicitly highlights their pitfalls. We then construct a cost-benefit optimization framework that incorporates species utility, ecological value, distinctiveness, and species interactions. This framework offers the theoretical foundations of a simple and operational method for the management of invasive species under a limited budget constraint. It takes the form of an algorithm for the prioritization of multiple biological invasions.

“…During establishment and expansion, an invading population may rapidly evolve in response to selection pressures generated by the novel abiotic and biotic conditions (Lee 1999;Huey et al 2000). At the same time, the invading population may alter the evolutionary pathways of the invaded populations directly by stimulating adaptive responses (Carroll and Dingle 1996) or indirectly by predation (Rodda and Fritts 1997), niche displacement (Race 1982), and competitive exclusion (Holway 1999;Wauters and Gurnell 1999). The impact of competitive exclusion can be further exacerbated by hybridization.…”

Abstract. The invasion of Africanized honeybees (Apis mellifera L.) in the Americas provides a window of opportunity to study the dynamics of secondary contact of subspecies of bees that evolved in allopatry in ecologically distinctive habitats of the Old World. We report here the results of an 11-year mitochondrial DNA survey of a feral honeybee population from southern United States (Texas). The mitochondrial haplotype (mitotype) frequencies changed radically during the 11-year study period. Prior to immigration of Africanized honeybees, the resident population was essentially of eastern and western European maternal ancestry. Three years after detection of the first Africanized swarm there was a mitotype turnover in the population from predominantly eastern European to predominantly A. m. scutellata (ancestor of Africanized honeybees). This remarkable change in the mitotype composition coincided with arrival of the parasitic mite Varroa destructor, which was likely responsible for severe losses experienced by colonies of European ancestry. From 1997 onward the population stabilized with most colonies of A. m. scutellata maternal origin.

“…These densities were suf cient to exert suppression on prey populations such as never before observed in a snake species (Rodda et al 1997). Originating at Naval Base Guam in the late 1940s or early 1950s, the invasion front spread from there to the southern tip of Guam by the late 1960s and reached the more remote northern limestone forests by the early 1980s (Savidge 1987).…”
