The storage method used to gather aquatic invertebrates has not been standardised across the scientific community, and the effects of common storage methods on the organism's microbial composition are uncertain. Both the bacterial community was preserved for two samples of field-collected crayfish frozen in ethanol or frozen, as was the aquarium crayfish's gut microbiome. However, there were significant differences between the bacterial cultures discovered on the exoskeleton of aquarium crayfish stored in ethanol compared to those that were frozen. The microbiome was preserved between storage methods, showing significant differences in gut microbial composition between species of gut microbial composition, but storage methods maintained the microbiome. These results show that preserving aquatic invertebrates cultured in 95% ethanol is likely to be a simple and cost-effective sample preservation technique for subsequent gut microbiome testing, but not so good for the external microbiome.

With TSAIs being largely ignored in conceptual models, legislation, policy, and ecological monitoring, less is known about the species composition and ecological roles of TSAIs of IRES than their aquatic counterparts. We review the TSAI literature that has increased dramatically over the past decade in the last decade, as well as present conceptual models describing how TSAIs react to hydrological changes in IRES. We test these models in Australia and France during wet and dry seasons. Then, we test these models with results gathered during wet and dry phases of IRES. Water managers and policy makers alike can use these generic models to ensure that both wet and dry phases are considered in the planning and protection of IRES. Any hydrological stage, IRES should be treated as a habitat continuum through time, with taxa from a swath of aquatic, semi-aquatic, and terrestrial invertebrates inhabiting at any hydrological stage.

Both the bioacoustics and the animal responses to sounds associated with pre-construction, installation, and operations of offshore wind energy development are severely lacking. As the OSW industry grows, a taskgroup of the 2020 State of the Science Workshop on Wildlife and Offshore Wind Energy conducted research for the next five years to help stakeholders better understand the potential cumulative biological effects of sound and vibration to fishes and aquatic invertebrates. However, filling up significant knowledge will increase our knowledge of the potential effects of OSW energy development on populations and ecosystems.

Stem cells in vertebrates typically reside in "stem cell niches," morphologically restricted tissue microenvironments that are vital for SC survival and reproduction. The comparative analysis will allow for the future functional characterization of SCNs by both establishing the invertebrates SCNs as distinct species and simultaneously allowing inclusivity among them.

Invertebrates are key components of aquatic ecosystems and play a vital role in the change of matter and energy in continental water bodies. Aquatic invertebrates' communities are characterized by their vulnerability to environmental pollution by nutrients and toxic chemicals, as well as acidification of water bodies; they act as reliable bioindicators of the aquatic environment and hydroecosystems. The following dataset includes details on the aquatic invertebrate community of a large northern river.
