“…One of the key life-history traits that may facilitate Bythotrephes' rapid range expansion is its production of diapausing or resting eggs. These sexually-produced, diploid eggs remain viable after passage through fish gastrointestinal tracts (Jarnagin et al 2000), and may survive overland transport (Ketelaars and Gille 1994). If the fishing gear is subsequently used on another lake without cleaning, dried masses of females and resting eggs may fall off the line; viable resting eggs could then hatch and cause a new invasion.…”

Predicting dispersal of nonindigenous species (NIS) is an essential component of risk analysis and management, as preventative measures are most readily applied at this stage of the invasion sequence. Gravity models provide one of the most useful techniques available to model dispersal of nonindigenous invasive species (NIS) across heterogeneous landscapes, as these models are able to capture transport patterns of recreational boaters who are dominant vectors responsible for aquatic NIS dispersal. Despite the widespread use of gravity models in forecasting biological invasions, different classes of gravity models have not been evaluated regarding their comparative ability to capture recreational transport patterns and subsequent use in predicting NIS establishment. Here we evaluate model selection between unconstrained, total-flowconstrained, production-constrained and doubly-constrained stochastic gravity models to assess dispersal of the spiny waterflea Bythotrephes between Ontario lakes. Differences between the models relate to the amount of data required and constraints under which calculations of source/destination interactions are made. For each class of gravity model, we then estimated the probability of a lake having established Bythotrephes populations by modeling the relationship between empirical presence/absence data and inbound recreational traffic (i.e. propagule pressure) via boosted regression. The unconstrained gravity model provided the best fit to observed traffic patterns of recreational boaters. However, when output from the gravity models was used to predict Bythotrephes establishment, the doubly-constrained gravity model provided the strongest relationship between inbound recreational traffic and observed Bythotrephes presence/absence, followed by the production-constrained model. Our results indicate production-constrained gravity models offer an acceptable balance between modeling recreational boater traffic and their utility to estimate establishment probabilities.

“…Early genetic studies relied on allozyme variation to elucidate the points of origin of invading taxa. For example, allozyme studies determined that North American populations of the cladoceran Bythotrephes longimanus, a species with an invasion history in both Europe and Asia (Ketelaars and Gille 1994), were derived from Finland (Berg and Garton 1994). The origin of the North American populations of Dreissena bugensis from the Dnieper River was similarly elucidated using allozyme markers (Spidle et al 1994;Marsden et al 1996).…”

The predatory cladoceran Cercopagis pengoi has extended its range over the past decade from the Ponto-Caspian basin into the Baltic Sea and the Laurentian Great Lakes. This study employs mitochondrial DNA (mtDNA) sequence analysis to elucidate the invasion corridors exploited during this range expansion. The Caspian and Black Sea populations of C. pengoi exhibit marked genetic divergence, enabling their discrimination as potential sources of the Baltic and Great Lakes populations. The limited mtDNA haplotype diversity detected in the Baltic populations suggests they were founded by a small number of colonists from the Black Sea. The colonization of North America was apparently a result of the transfer of animals from the Baltic Sea in ballast water.

“…The nearly 1 : 1 ratio of piscivores to planktivores in the reservoir was not only higher than in natural lakes but contrasts with stocking patterns for this region, as natural lakes are more commonly stocked with piscivores (mainly walleye). Ketelaars and Gille (1994) also point to weak top-down control as a major cause for the success of B. longimanus in the Biesbosch reservoirs (Table 2) where, in addition to B. longimanus, it is noteworthy that the large invertebrate predator Leptodora kindtii also reaches exceptionally high densities.…”

“…Not surprisingly, a variety of studies have linked fish distribution, productivity, and diversity to the availability and diversity of littoral macrophytes (Randall et al 1996;Weaver et al 1997). Ketelaars and Gille (1994) cite damaged littoral zones in the Biesbosch reservoirs as a primary reason for low zooplanktivore densities. We suspect that this is also a factor in the low I plank indices in Island Lake and the other reservoirs compared to the natural lakes that we assessed.…”

We conducted a 3-yr study of the population dynamics of the invasive cladoceran Bythotrephes longimanus in Island Lake Reservoir (Minnesota) and compared our results to other human-constructed reservoirs and natural lakes to examine ecological differences of B. longimanus between these ecosystem types and to investigate how reservoirs facilitate invasion of this zooplankter. The maximum and mean densities (n 5 number of individuals) of B. longimanus were larger in Island Lake Reservoir (. 100 n m 23 and 20-57 n m 23 , respectively) and in most other reservoirs than in natural lakes. Island Lake Reservoir and most other reservoir populations also exhibited multiple (up to six) cycles of growth and collapse per season, and performed extensive diel vertical migrations (DVM) to near the lake bottom during the day. Multiple lines of evidence indicate that the population dynamics of B. longimanus in Island Lake Reservoir were governed by relaxed top-down control by fish predation and strong bottom-up control by food availability. Developmental stage-specific death rates predicted from a matrix model were density dependent, aligned with predictions of bottom-up control (e.g., largest for the smallest instars, and correlated with food resources), and were inconsistent with anticipated prey demands by fishes. The reproductive and DVM trends of B. longimanus also indicated food stress and abated top-down control, respectively. We propose a mechanistic basis for invasion success in reservoirs by linking several limnological attributes, including chlorophyll a, water level fluctuation, light penetration, and thermal conditions to increased growth potential of B. longimanus.
