Nutrient enrichment decreased the Cross-Taxon congruence across bacteria, fungi, and zoobenthos in sediment

open access: yesEcological Indicators
Eutrophication is a major problem currently affecting sediment biodiversity in different kingdoms. Surveys at different spatial scales have suggested that nutrient enrichment drove the congruence in biodiversity across different kingdoms.

Zooplankton and zoobenthos of national natural monument Pastvisko (Pasture land)

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2004
In the year 2002 the seasonal dynamic of zooplankton and zoobenthos in six localities of the national natural monument Pastvisko was observed. The localities belong to the lower Podyjí region, wetlands of international importance.

ZOOBENTHOS EFFECT AND THE ROLE OF ZOOBENTHOS IN THE NITROGEN METABOLISM IN A SHALLOW EUTROPHIC LAKE. [PDF]

open access: yesZOOBENTHOS EFFECT AND THE ROLE OF ZOOBENTHOS IN THE NITROGEN METABOLISM IN A SHALLOW EUTROPHIC LAKE.
Effects of zoobenthos, especially chironomid larvae and tubificid worms, usually dominated in eutrophic lakes, on sediment-water interface of lake bottom were discussed with special reference to the role of zoobenthos in nitrogen metabolism in a shallow eutrophic lake, Lake Suwa, Japan.

Zooplankton and zoobenthos of the ponds in the Žďár region

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2007
In the years 1989–2000, the species composition and seasonal dynamics of zooplankton and zoobenthos in six ponds in the Žďár region were monitored. Altogether 83 taxa of water invertebrates were determined. Size and species composition of zooplankton and

The zoobenthos structure in the Dniprovske (Zaporizke) reservoir, Ukraine [PDF]

open access: yes, 2020
The article presents data on monitoring the species composition of the zoobenthos of the Dnipro reservoir during 2015-2018. It has been found that a biocenosis of Dreissena (Dreissena bugensis, D polymorpha) was formed on the pass of the upper part of the reservoir on slightly silty sand.

Sympatric Speciation of Tibetan Loaches (<i>Triplophysa</i>) Driven by Dietary Niche Specialization. [PDF]

open access: yesEcol Evol
The sympatric speciation of Tibetan loaches in a semi‐enclosed postglacial lake on the Qinghai‐Tibet Plateau, which is driven by the synergistic mechanism of the gut microbiomes and dietary specialization. ABSTRACT The Qinghai‐Tibeta Plateau is a hotspot for endemic fish biodiversity.

A Guild-Based Ecological Assessment: Integrating Multi-Model Approaches to Reveal Key Environmental Associations for Waterbirds in Nansi Lake, China. [PDF]

open access: yesEcol Evol
In Nansi Lake, waterbird guild densities were consistently linked to environmental gradients, with negative responses to nutrients and sediment variables, but positive responses to fish diversity and periphyton. Piscivores specifically favored high dissolved oxygen and low nitrogen conditions.

Longitudinal Variation in Population Structure, Growth, and Reproductive Characteristics of <i>Squalidus argentatus</i>, Driven by Cascade Dams in the Largest Tributary of Dongting Lake. [PDF]

open access: yesEcol Evol
The Dongting Lake and the Xiangjiang River. ABSTRACT Cascade dams would affect directly and indirectly life history traits of fish through altering flow regime and habitats. Growth patterns and reproductive strategy of Squalidus argentatus were studied at the Yongzhou above cascade dams, Hengyang heavily regulated by cascade dams, Zhuzhou influenced by
