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 ...

Development of a flow‐sensitive macroinvertebrate index for Australian rivers
Abstract Hydrologically sensitive macroinvertebrate indices have been developed in Europe, the Americas and New Zealand to serve many purposes such as monitoring ecological responses to drought, flow regulation, water extraction and the provision of environmental flows.

The first record of Helobdella nuda (Hirudinida, Glossiphoniidae) in lake Baikal [PDF]
The First Record of Helobdella nuda (Hirudinida, Glossiphoniidae) in Lake Baikal. Kaygorodova I. A., Utevsky S. Yu. - By far, the leech species Helobdella nuda (Moore, 1924) was known from China and the Amur River basin. It is found to occur in shallow waters of Lake Baikal.

Abstract Sewage released from lakeside development can introduce nutrients and micropollutants that can restructure aquatic ecosystems. Lake Baikal, the world's most ancient, biodiverse, and voluminous freshwater lake, has been experiencing localized sewage pollution from lakeside settlements.

Abstract Leeches play important roles in food webs due to their abundance, diversity and feeding habits. Studies using invertebrate‐derived DNA (iDNA) extracted from leech gut contents to target vertebrate DNA have focused on the Indo‐Pacific region and mainly leveraged the leech family Haemadipsidae, composed of bloodfeeding terrestrial leeches, while

In our paper, four events of blood sucking on human by juvenile and adult specimens of Placobdella costata were described. We presented with a new data of juvenile specimens' body form and considered information about the potential role of mammals as hosts and dispersion vector of this leech.

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

Strong impacts of signal crayfish invasion on upland stream fish and invertebrate communities
Abstract Impacts of invasive signal crayfish Pacifastacus leniusculus on native species and ecosystems are widely recognised, but mostly through small‐scale studies and laboratory experiments that may not always reflect impacts in nature. Recorded effects of signal crayfish on fish populations are equivocal.
