Outcome of competition between two Daphnia species in the absence of predators: laboratory experiment findings support field observations

Autor: Gardea R. Simoke, Leif K. Hembre, August T. Henneck

Publikováno v: BIOS. 91

Zooplankton communities are typically comprised of smaller-bodied species when size-selective fish predators are abundant, but become dominated by large-bodied species when fish predators are scarce. Superiority by larger-bodied grazers over smaller-

Evolution of predator avoidance in a Daphnia population: evidence from the egg bank

Autor: Laura Ann Peterson, Leif K. Hembre

Publikováno v: Hydrobiologia. 700:245-255

Dormant propagule pools (egg banks) of zooplankton populations that accumulate in sediments provide biological archives of past conditions and enable the investigation of evolutionary changes in populations over relatively long periods of time (many

Direct and indirect effects of predation on the genetic structure of a Daphnia population

Autor: Leif K. Hembre, Robert O. Megard

Publikováno v: Journal of Plankton Research. 28:1129-1141

Communicating editor: K.J. Flynn The effects of fish predation on zooplankton communities are well documented, but relatively little is known about how predation structures the genetic composition of individual populations. This study illustrates how

Timing of predation by rainbow trout controls Daphnia demography and the trophic status of a Minnesota lake

Autor: Robert O. Megard, Leif K. Hembre

Publikováno v: Freshwater Biology. 50:1064-1080

Summary 1. Stocking of lakes with rainbow trout is a common practice that presents a potential conflict for lake managers who must balance the interests of anglers with those concerned that zooplanktivory by trout may trigger a trophic cascade and re

Seasonal and diel patchiness of a Daphnia population: An acoustic analysis

Autor: Robert O. Megard, Leif K. Hembre

Publikováno v: Limnology and Oceanography. 48:2221-2233

Detailed information about the location and extent of zooplankton patches is fundamental to understand how abiotic and biotic forces interact to structure the spatial distribution of zooplankton. We mapped zooplankton patchiness in a Minnesota lake d
