The objective of this study was to verify the richness and density of aquatic benthic macroinvertebrates after exposure to fungicides and insecticides of the rice paddy elds. In the crop seasons of 2012/13 and 2013/14, eld experiments were performed, which consisted of single-dose applications of the fungicides tri oxystrobin + tebuconazole and tricyclazole, and the insecticides lambda-cyhaloth...

Aquatic insects and other benthic macroinvertebrates are mostly used as bioindicators of the ecological status freshwaters. However, an expensive time-consuming process species identification represents one key obstacles for reliable biomonitoring aquatic ecosystems. In this paper, we proposed a deep learning (DL) based method that evaluated on several available public datasets (FIN-Benthic, ST...

Quantifying and understanding movement is critical for a wide range of questions in basic and applied ecology. Movement ecology is also fostered by technological advances that allow automated tracking for a wide range of animal species. However, for aquatic macroinvertebrates, such detailed methods do not yet exist. We developed a video tracking method for two different species of benthic macro...

The ecological effects of ocean acidification (OA) from rising atmospheric carbon dioxide (CO2) on benthic marine communities are largely unknown. We investigated in situ the consequences of long-term exposure to high CO2 on coral-reef-associated macroinvertebrate communities around three shallow volcanic CO2 seeps in Papua New Guinea. The densities of many groups and the number of taxa (classe...

A set of methodological tools were tested in order to assess the eutrophication quality of selected coastal areas in Eastern Mediterranean Sea, Greece, in the context of the Water Framework Directive under various anthropogenic pressures. Three, five-step tools, namely, TRIX, chlorophyll-a (chl-a) biomass classification scheme, and eutrophication index (E.I.) were applied in oligotrophic waters...

The direct effects of a Virginia trout farm on benthic macroinvertebrates were examined using multiple approaches. Static laboratory tests with the amphipod, Hyallela azteca, were conducted with exposures to water taken from a spring and from effluent both above and below a sedimentation basin. Onsite mesocosms were constructed to expose previously colonized artificial substrates to the same tr...

Parasitism has long been emphasised as an important process structuring animal communities. However, empirical evidence documenting the impact of parasites in other than simple laboratory settings is lacking. Here we examine the trait-mediated indirect effects of echinostome trematodes on a New Zealand soft bottom intertidal community of macroinvertebrates. Curtuteria australis and a second rel...

The objective of this study was to verify the richness and density of aquatic benthic macroinvertebrates after exposure to fungicides and insecticides of the rice paddy fields. In the crop seasons of 2012/13 and 2013/14, field experiments were performed, which consisted of single-dose applications of the fungicides trifloxystrobin + tebuconazole and tricyclazole, and the insecticides lambda-cyh...

We examined inter-habitat variation in benthic macroinvertebrate assemblages in the 180-km Garrison Reach of the Upper Missouri River, North Dakota (USA) in 2001–2003. The Garrison Reach is unchannelized with a mostly rural setting. Flows are regulated by Garrison Dam.We sampled benthos from three habitats defined a priori: channel, shoreline, and backwater. Benthic assemblages were different i...

The ecosystem effects of Limnoperna fortunei have been studied nationally in recent years. However, the interactions that this invader establishes with native benthic fauna not determined detail. objective study was to collect information on between golden mussel and macroinvertebrates Uruguay River, through (a) bibliographic survey, (b) photographic record obtained field (c) analysis data from...
