Ecology: It is most likely that D. lumholtzi has become a successful invader because of its ability to avoid predation, not because it is a better competitor for the available food supply. Stomach samples of fish from Norris Reservoir contained no D. lumholtzi (Goulden et al. 1995). Work and Gophen (1999) note three aspects of D. lumholtzi that have most likely contributed to its success as an invader in North America. First, due to its tropical to subtropical native range, D. lumholtzi is adapted to higher temperatures than is native Daphnia. Second, D. lumholtzi is adapted to disturbed areas, giving it an invasion advantage (according to invasion theory). Third, the long helmet and tail spine helps D. lumholtzi avoid predation.

Like other Daphnia, D. lumholtzi produces ephippia (resting eggs). All ephippia are resistant to adverse environmental conditions and can lay dormant in sediment for long periods of time delaying hatching until optimal conditions are present. The ephippia of D. lumholtzi have hairs and spines that could grip boats or other objects and thus aid dispersal (Dzialowski et al. 2000).

Means of Introduction: It is uncertain how D. lumholtzi was introduced into the U.S. It is suspected that it may have been transported with shipments of Nile perch from Lake Victoria in Africa where it is a dominant zooplankter. Nile perch was originally introduced into Texas as early as 1983 (Havel and Hebert 1993). The continuing discovery of D. lumholtzi in new locations could be due to contaminated stockings of fish through international commercial trade. At the same time, the close proximity of affected reservoirs in Missouri and in Texas might lead to the conclusion that D. lumholtzi may have spread by recreational boating from the initially infested reservoirs. 

Dzialowski et al. (2000) found that non-human dispersal mechanisms had little to do with the spread of D. lumholtzi in Kansas. D. lumholtzi was not detected in small ponds inaccessible to boats, even though the ponds were within watersheds where D. lumholtzi was established (Dzialowski et al. 2000). Because of rapid and widespread introductions, D. lumholtzi may become a dominant zooplankter in the southern U.S. (Havel et al. 1995).

Status: Daphnia lumholtzi has been collected for several consecutive years in Norris Reservoir (part of the Tennessee River system in Tennessee) and in several reservoirs in Missouri. The range of D. lumholtzi is expanding throughout eastern Kansas (Dzialowski et al. 2000)

Impact of Introduction: The impacts of this invader are not yet fully understood. It competes with native daphnia for food and of its ability to avoid predation (U.S.EPA 2008).   

Studies that have compared native Daphnia to the exotic D. lumholtzi have found that competition between these species is lower than expected. D. lumholtzi is a tropical species, and is adapted to warmer temperatures than native North American Daphnia. Thus D. lumholtzi population sizes tend to rise in late summer when native Daphnia populations are dropping. Thus D. lumholtzi tends to fill a vacant "temporal niche" in the warmer summer months (Johnson and Havel 2001; Work and Gophen 1999; Dzialowski et al. 2000; Goulden et al. 1995; East et al. 1999). Dzialowski et al. (2000) hypothesized that by occupying a niche that was previously unexploited by Daphnia, D. lumholtzi competed with non-daphnid zooplankton otherwise able to obtain resources during that time. One such zooplankter was Diaphanasoma, whose population was found to be significantly lower in reservoirs of Kansas where D. lumholtzi had invaded (Dzialowski et al. 2000). If D. lumholzi has a negative impact on other native zooplankton populations in late summer, this may have a detrimental effect on fishes that depend on zooplankton at that time period but are not able to handle the spines of D. lumholtzi.

Larval and juvenile stages of fish that overlap with high D. lumholtzi populations are more likely to be negatively impacted by D. lumtoltzi due to gape limitation (Kolar and Wahl 1998). Leinesch and Gophen (2001) noted that fish large enough to handle D. lumholtzi spines would have a new prey item with a larger overall body size than the zooplankton normally present in the later summer months. Lemke et al. (2003) studied four fish species that consumed more D. lumholtzi as fish size increased (blue gill, white bass, white crappie, and black crappie of Lake Chautauqua, Illinois). Silversides (Menidia beryllina) may be able to utilize this new prey item and survive longer during their late summer spawning period (Leinesch and Gophen 2001). Leinesch and Gophen (2001) hypothesized that when growing juvenile fish become capable of handling D. lumholtzi, the fish can grow more rapidly and reduce their risk of predation.

Remarks: Nutrient and resource levels in lakes likely play a large role in the presence and spread of D. lumholtzi throughout the United States, though research on mechanism is unclear. Dzialowski et al. (2000) suggested that low resource (algae) levels aid D. lumholtzi invasion because it is better able to take advantage of low quality food resources than small competitors, but Havel et al. (1995) found that reservoirs invaded by D. lumholtzi had much higher levels of nutrients than non-invaded reservoirs. Further research is warranted to clarify discrepancies.
