Tropic interactions within South African intertidal mussel beds
… shown to be strongly influenced by trophic interactions, particularly interactions between predators of mussels and their prey. This investigation involved, firstly, construction of models to simulate trophic interactions in the mussel beds of the west coast of South Africa under different …

Population oscillations in continuous culture of the prey-predator systems Escherichia coli - Dictyostelium discoideum and Proteus vulgaris - Dictyostelium discoideum
… in a continuous flow culture of prey-predator interactions was made. A Coulter Counter was used to enumerate the population levels and periodic checks were performed with a Petroff-Hausser bacterial counts. Population oscillations of both prey and predator occurred in the continuous …

Investigating Mechanisms of Co-Occurrence Between Two Similar Specis of Predaceous Diving Beetles (<i>Coleoptera: Dytiscidae</i>) in Temporary Aquatic Habitats
… are hypothesized to have strong interspecific interactions. I investigated several possible mechanisms that may promote such coexistence, including segregation in habitat domain, differences in behavior, and differences in dispersal that may allow co-occurrence between these two species of …

Variation in predator communities and anti-predator behaviors of Milne-Edwards' sifakas (Propithecus edwardsi) in southeastern Madagascar
… Madagascar, we must examine the persistence and interactions of species in human-disturbed habitats. I investigated lemur-predator interactions in southeastern Madagascar through a comparison of predator communities and anti-predator behaviors of Milne-Edwards' sifakas (Propithecus edwardsi) in …

The Effects of noise of Zebrafish (Danio rerio) memory
… as communication, feeding, breeding, and prey-predator interactions to physiological alterations in hormones levels or even severe damages to internal organs. In this study, I investigated the effects of white noise on the cognitive performance of zebrafish (Danio rerio) and its possible …

Aspects of the ecology and management of small mammalian predators in northern New Zealand
… at Trounson Kauri Park, Northland New Zealand. Predatory mammals were monitored by radio telemetry through a 1080 then brodifacoum poison baiting operation at Trounson Kauri Park in Northland, New Zealand to target possums (Trichosurus vulpecula) and rodents (Rattus rattus, Rattus norvegicus & …

Competitive interactions among two specialist predators and a generalist predator of hemlock woolly adelgid, <i>Adelges tsugae </i>Annand (Hemiptera: Adelgidae)
Competitive interactions among two specialist predators, <i>Laricobius nigrinus</i> Fender (Coleoptera: Derodontidae) and <i>Sasajiscymnus tsugae</i> Sasaji and McClure (Coleoptera: Coccinellidae), and a generalist predator, <i>Harmonia axyridis</i> Pallas (Coleoptera: Coccinellidae), of hemlock …
