Comparative studies on a zooplankton–fish model subjected to infection in zooplankton with varying rates of disease transmission

open access: yesFranklin Open
Eco-epidemiological models offer practical demonstrations of non-linear dynamics, enriching the realm of mathematical biology. The importance of viruses in oceanic plankton ecosystems is becoming more widely acknowledged.

Community composition of zooplankton and macroinvertebrates of Chelekleka wetland, Ethiopia, and the seasonal visitation of greater flamingo (Phoenicopterus roseus)

open access: yesGlobal Ecology and Conservation
Greater flamingos (Phoenicopterus roseus) are key species in wetlands and feed mainly on zooplankton and macroinvertebrates. Little is known about the zooplankton and macroinvertebrate communities of East African wetlands and the relationship with the ...

Diel vertical migration strategies of zooplankton in oligotrophic Russell Pond, New Hampshire [PDF]

open access: yes, 2014
Russell Pond is an ultra-oligotrophic lake with low chlorophyll a (1.9 mg L-1), total phosphorus (3.4 mg L-1), high Secchi Disk (10.4 m) and high light transmission (water coefficient of water, kw=0.33). Vertical migration of Chaoborus, Bosmina, Daphnia,

Exploring indirect effects of a classic trophic cascade between urchins and kelp on zooplankton and whales

open access: yesScientific Reports
Kelp forest trophic cascades have been extensively researched, yet indirect effects to the zooplankton prey base and gray whales have not been explored. We investigate the correlative patterns of a trophic cascade between bull kelp and purple sea urchins

Evaluation of climate change scenarios based on aquatic food web modelling [PDF]

open access: yes, 2008
In the years 2004 and 2005 we collected samples of phytoplankton, zooplankton and macroinvertebrates in an artificial small pond in Budapest. We set up a simulation model predicting the abundance of the cyclopoids, Eudiaptomus zachariasi and Ischnura ...
