Structure and spatial distribution of the rotifer assemblages along a tropical reservoir

open access: yesBrazilian Journal of Biology
The construction of reservoirs is a common practice in the world. These systems modify the hydric landscape and alter the flow of rivers, becoming lotic environments in lentic. Here we investigated the structure and spatial distribution of rotifers along

An overview of Synchaeta Ehrenberg, 1832 (Rotifera: Monogononta: Synchaetidae) species in the Eastern Gotland Basin, Baltic Sea, with complementary characteristics for the trophi of S. fennica Rousselet, 1902 and S. monopus Plate, 1889; pp. 287–294 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2017
Four species of the genus Synchaeta were identified in the waters of Liepaja harbour (coastal Eastern Gotland Basin, Baltic Sea). Synchaeta baltica and S. monopus are common in the Baltic Sea and they co-dominated most of the samples.

Warm‐wet transition restructures arid lake microbiomes and functional potential

open access: yesiMetaOmics, EarlyView.
This study summarizes how a long‐term warm‐dry to warm‐wet transition restructures microbiomes and functional potential in Lake Bosten, an arid lake in northwestern China. Warm‐wet hydroclimatic change increased water level and hydrological connectivity, while decreasing salinity and total nitrogen.

Effects of environmental factors on species diversity of rotifers using biodiversity indicators and canonical correlation analysis (CCA) [PDF]

open access: yesبوم‌شناسی آبزیان, 2017
Rotifers are microscopic aquatic animals of phylum Rotifera, live in a diverse range of aquatic habitats. They are important in ecology of freshwater ecosystems by recycling nutrients and can alter trophic dynamic of planktonic communities.

Impact of water level fluctuation in the shaping of zooplankton assemblage in a shallow lake.

open access: yesCroatian Journal of Fisheries, 2018
Shallow lakes are strongly affected by global climate changes reflected in significant parameters of ecosystem deterioration, i.e. biodiversity decrease, and water turbidity.

Zooplankton Biodiversity in Reservoirs of Different Geographical Regions of Turkey: Composition and Distribution Related with Some Environmental Conditions

open access: yesAquatic Sciences and Engineering, 2019
The zooplankton fauna and the relationship with their environmental variables were investigated on the epilimnion layer of the seven reservoirs (Demirdöven, Devegeçidi, Menzelet, Sır, Ömerli, Porsuk, Tahtalı) of different regions (Marmara, Aegean ...

Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Glyphosate is one of the most widely used herbicides in the world, including in Brazil, and its dispersion through habitats and surface waters can impact entire aquatic ecosystems. However, experimental studies evaluating the effects of pesticides on whole planktonic communities, considering attributes such as richness, density and composition—

Zooplankton diversity in Philippine Lakes [PDF]

open access: yes, 2001
Sustainable fisheries development partly depends on the availability of adequate zooplankton as principal food items of early life history stages of economically important fish species as well as of the adults of some species such as clupeids (e.g ...
