Zooplankton Communities

The crustacean zooplankton communities in Lakes Michigan and Huron and the central and eastern basins of Lake Erie have shown substantial, persistent changes since the invasion of the predatory cladoceran Bythotrephes in the mid-1980s. A number of cladoceran species have declined dramatically since the invasion, including Eubosmina coregoni, Holopedium gibberum, Daphnia retrocurva, Daphnia pulicaria, and Leptodora kindti, and overall species richness has decreased as a result. Copepods have been relatively unaffected, with the notable exception of Meso cyclops edax, which has virtually disappeared from the lakes. These species shifts have for the most part been consistent and equally pronounced across all three lakes. Responses of crustacean species to the Bythotrephes invasion do not appear to be solely a consequence of size, and it is likely that other factors, e.g., morphology, vertical distribution, or escape responses, are important determinants of vulnerability to predation. Our results indicate that invertebrate predators in general, and invasive ones in particular, can have pronounced, lasting effects on zooplankton community structure.

Abstract Harsh and unstable aquatic environments present selective forces that influence environmental heterogeneity, dispersal capacity and specific life history strategies that, in turn, affect species distribution and metacommunity dynamics. To date, relatively few studies have examined the potential of bird-mediated dispersal to connect isolated ephemeral habitats. We used zooplankton from temporary ponds to examine the effects of bird morphological diversity and water availability on microcrustacean diversity in temporary ponds. Three bird feet models were constructed based on small, large and webbed anisodactylous forms in order to simulate bird walking on the pond shore. Bird and zooplankton communities were sampled in two temporary ponds and experimentally simulated zooplankton dispersal by bird on dry sediments. We surveyed in two contrasting seasonal periods. Overall, water availability does affect zooplankton composition, and birds with large feet have higher dispersal capacity. In addition, birds with different feet size and shape carry distinct zooplankton species. During the dry season, sediments hold 100% more species than in the wet season, which indicates that birds have higher potential for dispersing zooplankton in drought conditions. Our findings suggest that bird diversity can maintain zooplankton metacommunities by rescuing dormant organisms from dry ponds and connecting to any available aquatic habitats.

Zooplankton Communities

Identifying thresholds of biotic community change along stressor gradients may be useful to both ecologists and lake managers; however, there are several weaknesses in the thresholds that have been identified for zooplankton communities along acidity gradients. The thresholds are often based on a single species even though pH sensitivities vary among species. They often measure changes in species occurrences, though abundances may be a more responsive indicator of damage. Their identification may be confounded by spatial and morphometric factors if they are derived from lake surveys. Finally, the thresholds have usually been subjectively identified. Our goal was to establish a threshold in zooplankton community change along an acidity gradient that did not have these four common weaknesses. We used two crustacean zooplankton community metrics: species richness and scores of a correspondence analysis based on species abundances. Spatial and morphometric patterns were detected in the zooplankton community data and then extracted. The relationship between zooplankton and acidity was then modeled using a step function that objectively identified a threshold of community change at pH 6 for lakes in south-central Ontario.
