Evaluating Methods of Preserving Aquatic Invertebrates for Microbiome Analysis.

The storage procedure used to collect aquatic invertebrates has not been standardised in the scientific community, and the effects of common storage methods on the organism's microbial composition are uncertain. We discovered that the bacterial community was preserved for two specific species of field-collected crayfish stored either in ethanol or frozen, as well as aquarium crayfish's gut microbiome. However, there were significant differences between the bacterial cultures found on the exoskeleton of aquarium crayfish stored in ethanol compared to those that were frozen. The microbiome was conserved between storage methods, indicating significant differences in gut microbial composition between species of the digestive tract, but storage methods preserved the microbiome. These results show that preserving aquatic invertebrates cultured in 95% ethanol is expected to be a quick and cost-effective sample preservation strategy for subsequent gut microbiome analysis, but not so effective for the external microbiome.

The terrestrial and semi-aquatic invertebrates of intermittent rivers and ephemeral streams.

TSAIs of IRES are less well understood in conceptual models, legislation, policy, and ecological monitoring, with TSAIs being somewhat less popular in conceptual models, legislation, policy, and ecological monitoring. Herein we review the TSAI literature that has increased dramatically over the past decade, as well as present conceptual models describing how TSAIs respond to hydrological changes in IRES. These models are validated by us and France during wet and dry seasons in IRES. Wen, we validate these models with results obtained during wet and dry phases in IRES. Water managers and policy makers can use these generic models to ensure that both wet and dry phases are considered in the planning and protection of IRES. IRES should be considered as a habitat continuum through time, with taxa from a pool of aquatic, semi-aquatic, and terrestrial invertebrates inhabiting at any hydrological stage.
