Seasonal Diversity and Morphometric Variations of Rotifers in Relation to Selected Environmental Variables from a Tropical High-Altitude Lake in Mexico

open access: yesDiversity, 2023
We studied the species diversity and morphometric variations of rotifers from a high-altitude water body, the Llano reservoir, in central Mexico during September 2021 to August 2022. Samples were collected from four stations in the reservoir every month.

The role of paleolimnology in climate and environment reconstruction and lake restoration in light of research on selected bioindicators [PDF]

open access: yesThe Holistic Approach to Environment, 2020
Paleolimnologists and ecologists study biotic and abiotic variables to track long-term and short-term environment changes. Microscopic invertebrates, phytoplankton of freshwater ecosystems, and pollen grains have been extensively studied during the last ...

Zooplankton communities in a river downstream from a lake restored with hypolimnetic withdrawal

open access: yesKnowledge and Management of Aquatic Ecosystems, 2020
Restoring lakes with hypolimnetic withdrawal can severely threaten water quality and biocenosis downstream. The objective of this study was to evaluate the effect of lake restoration on riverine zooplankton during a period of intense hypolimnion water ...

Rotifera from Burundi : the Lecanidae (Rotifera : Monogononta) [PDF]

open access: yesAnnales de Limnologie - International Journal of Limnology, 2000
As part of a survey of the rotifer fauna of Burundi, Lecanidae from Kashira and the floodplain of the river Rusizi in Northwest Burundi are reported. Thirty-four species of Lecane were found. Twenty-five of them are new to Burundi, raising the total Burundian Lecane record to thirty-five. Three species, Lecane aeganea Harring, 1914, L.

Zooplankton community responses to the mixture of imazethapyr with imazapic and bispyribac-sodium herbicides under rice paddy water conditions

open access: yesCiência Rural, 2014
The aim of this study was to assess the effect of concentrations of imazethapyr, imazapic, and bispyribac-sodium herbicides on zooplankton community (Cladocer, Copepod and Rotifer) in rice paddy fields. The decrease of half-life dissipation (DT50) of the

Tardigrades and oribatid mites in bryophytes from geothermally active lava fields (Krafla, Iceland) and the description of Pilatobius islandicus sp. nov. (Eutardigrada) [PDF]

open access: yesPolish Polar Research, 2018
In polar regions, apart from tundra and glaciers, geothermally active areas with elevated temperatures are important elements of ecosystems. One such geothermally active region characterized by mosaic ecosystems and vast areas covered by recent lava ...

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
