Evolutionary tradeoff and equilibrium in an aquatic predator-prey system [PDF]

open access: yes, 2004
Due to the conventional distinction between ecological (rapid) and evolutionary (slow)timescales, ecological and population models to date have typically ignored the effects of evolution.

A first step to assess suspended microplastics in a freshwater wetland from the coastal region of Ecuador

open access: yesFrontiers in Environmental Science, 2023
Introduction: La Segua is an important wetland in Ecuador, recognized as a Ramsar site and of great ecological relevance. Currently, La Segua is threatened by human pressures and unsustainable landscape use associated with agriculture and aquaculture ...

The effects of zinc-enriched Saccharomyces cerevisiae on the growth and mineral composition of marine rotifer, Brachionus plicatilis

open access: yesInternational Journal of Aquatic Biology, 2018
Rotifers are important zooplankton in commercial finfish hatcheries. However, due to the limited variety of food available, zinc content of cultured rotifers in artificial environments may not meet the requirements of fish larval.

Soil Rotifers new to Hungary from the floodplain Gemenc (Duna-Dráva National Park, Hungary) [PDF]

open access: yes, 2013
In summer and autumn 2010, we collected soil samples from the Gemenc floodplain of the Danube (Duna-Dráva National Park) from places with different flood regimes and vegetation cover and examined them for rotifers.

Comparative genomics of bdelloid rotifers: Insights from desiccating and nondesiccating species

open access: yesPLoS Biology, 2018
Bdelloid rotifers are a class of microscopic invertebrates that have existed for millions of years apparently without sex or meiosis. They inhabit a variety of temporary and permanent freshwater habitats globally, and many species are remarkably tolerant

Experimental Studies on Zooplankton-Toxic Cyanobacteria Interactions: A Review

open access: yesToxics, 2023
Cyanobacterial blooms have been recognized as a problem in fresh water for about 150 years. Over the past 50 years, experimental studies on the subject have gained importance considering the increasing need to control toxic cyanobacterial blooms.

Rotifers: Exquisite Metazoans [PDF]

open access: yesIntegrative and Comparative Biology, 2002
Rotifers comprise a modestly sized phylum (≈1,850 species) of tiny (ca. 50-2,000 μm), bilaterally symmetrical, eutelic metazoans, traditionally grouped within the pseudocoelomates or Aschelminthes. These saccate to cylindrically shaped protostomes possess three prominent regions (corona, trunk, foot).

Rotibot: Use of Rotifers as Self‐Propelling Biohybrid Microcleaners

open access: yesAdvanced Functional Materials, 2019
Self‐propelled biohybrid microrobots, employing marine rotifers as their engine, named “rotibot,” are presented and their practical utility and advantages for environmental remediation are demonstrated.
