First record of Bothrioneurum vejdovskyanum Štolc, 1886 (Oligochaeta, Tubificidae) in Serbia [PDF]

Archives of Biological Sciences, 2012
We report the discovery of Bothrioneurum vejdovskyanum Štolc, 1886 (Annelida: Oligochaeta: Tubificidae: Rhyacodrilinae) in Serbian freshwaters. Fifteen specimens were found in the middle course of the River Ibar (southern Serbia), at a locality where ...

Declines in prey production during the collapse of a tailwater Rainbow Trout population are associated with changing reservoir conditions

Transactions of the American Fisheries Society, Volume 152, Issue 1, Page 35-50, January 2023., 2023
Abstract Objective Understanding how energy moves through food webs and limits productivity at various trophic levels is a central question in aquatic ecology and can provide insight into drivers of fish population dynamics since many fish populations are food limited.

Freshwater macroinvertebrate traits assessment as complementary to taxonomic information for mining impact detection in the northern Peruvian Andes

Diversity and Distributions, Volume 28, Issue 8, Page 1582-1596, August 2022., 2022
Abstract Aim We studied the distribution of freshwater macroinvertebrate taxa and traits to distinguish ecological gradients among the mining‐controlled and natural headwaters, and rural and urban economic activity influences. Location In 2016’s dry season, macroinvertebrate samples were collected at 40 locations in the Mashcon watershed, northern ...

Impacts of shelter on the relative dominance of primary producers and trophic transfer efficiency in aquatic food webs: Implications for shallow lake restoration

Freshwater Biology, Volume 67, Issue 6, Page 1107-1122, June 2022., 2022
Abstract Wind‐induced turbulence can strongly impact ecological processes in shallow lake ecosystems. The creation of shelter against wind can be expected to affect both primary producers and herbivores in aquatic food webs. Shelter may benefit particular primary producers more than others by changing relative resource availabilities for different ...

Can artificial ecological islands alter the biodiversity of macroinvertebrate? A case study in Fujin National Wetland Park, the Sanjiang Plain, China

Ecology and Evolution, Volume 11, Issue 21, Page 14988-15003, November 2021., 2021
This paper proves that it is feasible to build artificial ecological islands in open water to increase the microhabitat heterogeneity and water‐level gradient as a means of ecological restoration, so as to provide more suitable habitats for aquatic organisms and thus increase the biological diversity of the ecosystem. Macrobenthos are the main food for

Invertebrate zoogeomorphology: A review and conceptual framework for rivers

WIREs Water, Volume 8, Issue 5, September/October 2021., 2021
Invertebrates affect the transport of sediment in rivers but are often overlooked due to their small size. Diverse behaviors result in significant effects on fluvial geomorphology. Abstract Invertebrates are important sediment engineers, making up for their small body size with abundance and behavioral diversity.

Enhancing ecological integrity while preserving ecosystem services: Constructing soft‐sediment islands in a shallow lake

Ecological Solutions and Evidence, Volume 2, Issue 3, July–September 2021., 2021
The Marker Wadden project shows how forward‐looking sustainable development of lake ecosystems using a rewilding approach can enhance natural processes and attract birds and fish, without conflicting with existing ecosystem services. This inspires new directions for halting and reversing the degradation of other vital ecosystems worldwide.
