Bioindication of the Influence of Oil Production on Sphagnum Bogs in the Khanty-Mansiysk Autonomous Okrug–Yugra, Russia

open access: yesDiversity, 2019
Algal diversity in the bogs of the Ershov oil field of the Khanty-Mansiysk Autonomous Okrug−Yugra (KMAO-Yugra) with the gradient of oil pollution between 255 and 16,893 mg kg−1 has been studied with the help of bioindication methods and ...

Late Quaternary changes in moisture availability and weathering intensity on the central Tibetan Plateau indicated by chemical signatures of ostracod shells

open access: yesFrontiers in Earth Science, 2022
High-resolution multi-proxy records from two lakes on the southern Tibetan Plateau, Nam Co and Tangra Yumco, are used to infer long-term variations in the Asian monsoon system with a novel set of ostracod shell chemistry proxies.

Diversity of the Summer Phytoplankton of 43 Waterbodies in Bulgaria and Its Potential for Water Quality Assessment

open access: yesDiversity, 2023
The general awareness of the threats on biodiversity and water quality raised the number of studies that use phytoplankton in assessment procedures. Since most metrics require obtaining mean values, this paper presents data that may help speed up field ...

Macrophytes as bioindicators [PDF]

open access: yesRiver Systems, 2003
Submerged macrophytes respond to changes in the nutrient concentrations in their environment. In contrast to diatoms e.g., submerged macrophytes are capable of taking up nutrients from both the sediment pore water and the overlying water. Therefore, macrophytes can provide a more comprehensive assessment of river ecosystems. Two methods using submerged

Migratory Songbirds as Potential Ectozoochorous Protist Dispersal Vectors. [PDF]

open access: yesEcol Evol
We demonstrate that migratory songbirds carry diatoms (Bacillariophyta) in their plumage, revealing an unexpected avian–algal association. All seven bird specimens we examined contained diatoms—224 frustules representing 25 genera and 9 orders, primarily freshwater, benthic pennates—some retaining chloroplasts prior to digestion and mounting (implying ...

Integral assessment of the environment using the bioindication methods [PDF]

open access: yesBIO Web of Conferences
Bioindication is an assessment of environmental factors and their dynamics based on the properties of ecological or biological systems. Bioindication methods are easily applied in monitoring of the environment. Bioindication is one of the areas of modern

Innovative observation of the environment. Bioindicators and biomonitors: definitions, strategies and applications / Aplinkos stebėsenos naujovės. Bioindikatoriai ir biomonitoriai: apibrėžtys, strategijos ir taikymas

open access: yesJournal of Environmental Engineering and Landscape Management, 2012
For a number of years “classical” programs for environmental monitoring are being supplemented by bioindication measures. Investigations on living organisms or their remains (e.g.

Is there a common threshold to subfossil chironomid assemblages at 16 m water depth? Evidence from the Tibetan Plateau

open access: yesJournal of Limnology, 2020
Fluctuating lake levels are an important driver of ecosystem change, and changes in the precipitation/evaporation balance of a region can lead to undesirable changes in ecosystem functioning. Large-scale changes in hydrology will become increasingly more

Lichens as biological indicators of air quality in the urban area of Kuršumlija (Southern Serbia) [PDF]

open access: yesKragujevac Journal of Science, 2017
In this work, we provided a first indication of Kuršumlija (town of Southern Serbia) air quality using epiphytic lichens known as bioindicators. The investigations were carried out from April to October 2014.

Sponges as bioindicators for microparticulate pollutants? [PDF]

open access: yesEnvironmental Pollution, 2020
ABSTRACT Amongst other threats, the world’s oceans are faced with man-made pollution, including an increasing number of microparticulate pollutants. Sponges, aquatic filter-feeding animals, are able to incorporate fine foreign particles, and thus may be a potential bioindicator for microparticulate pollutants.
