We conducted a study to determine the contribution of lethal and nonlethal effects to a
predator's net effect on a prey's population growth rate in a natural setting. We focused on …

Using historical (1970) and more recent (1996) Lake Erie plankton and trophic status data,
we developed a Planktonic Index of Biotic Integrity (P-IBI) to measure changes in lake …

Invasive species represent a threat to aquatic ecosystems globally; however, impacts can be
heterogenous across systems. Documented impacts of invasive zebra mussels (Dreissena …

Rarely do ecologists have the data needed to assess the impacts of invading species on
biodiversity, ie pre‐and post‐invasion census information from both invaded and control …

Invasions of aquatic habitats by non-indigenous species (NIS), including zooplankton, are
occurring at an alarming rate and are causing global concern. Although hundreds of such …

Oligotrophic lakes are generally dominated by calanoid copepods because of their
competitive advantage over cladocerans at low prey densities. Planktivory also can alter …

Abstract Changes in water clarity (secchi disc transparency) in relation to the
presence/absence of introduced, exotic fish, including rudd (Scardinius erythrophthalmus) …

Bien que le cladocère prédateur non indigène Bythotrephes longimanus se répande
rapidement dans les lacs du Bouclier canadien, il n'existe qu'une seule évaluation de son …

Species invasions are a leading threat to ecosystems globally, but our understanding of
interactions among multiple invasive species and their outcomes on ecosystem properties is …

Ecosystems can undergo abrupt regime shifts as a result of many factors. Shifts between
turbid and clearwater states are well understood for human‐impacted shallow lakes, but are …
