AI Article Synopsis
- Water mites are crucial to aquatic ecosystems, but their biodiversity is not well understood, prompting a study in the Detroit River to analyze their assemblages using both morphology and DNA barcoding techniques.
- The research involved collecting water mites from Blue Heron Lagoon, identifying several species, and reporting novel DNA barcodes that may indicate previously unknown variants or new species.
- Findings reveal that while the prevalence of water mites is higher in summer, diversity is lower during summer and winter, peaking during transitional seasons, suggesting that seasonal changes act as an intermediate disturbance that enhances biodiversity.
Article Abstract
Water mites are important constituents of aquatic ecosystems, but their biodiversity is poorly understood. The goal of this study was to improve knowledge of water mite assemblages in the Detroit River through combined use of morphological and cytochrome oxidase I (COI) DNA barcode data and to elucidate seasonal water mite diversity. The diversity of water mites collected from Blue Heron Lagoon at Belle Isle, an island in the Detroit River, is described. Novel DNA barcodes for Albia, Hydrochoreutes, Madawaska, and Axonopsis are reported with a species level barcode for Lebertia. Novel DNA barcodes may represent the presence of previously undescribed variants or new species of several genera. The prevalence of water mites is higher in the summer, but a different pattern is observed for diversity. The diversity of water mites, by several measures, varies seasonally with lower diversity in summer and winter months and higher diversity during seasonal transitions. For these organisms, we interpret seasonal change as an intermediate disturbance resulting in increased biodiversity.

The complexities of non-target effects of registered pesticides on biocontrol agents (BCAs) hinder the optimization of integrated pest management programs in agriculture. The wealth of literature on BCA-pesticide compatibility allows for the investigation of factors influencing BCA susceptibility and the generalized impacts of different pesticides. We conducted a meta-analysis using 2088 observations from 122 published articles to assess non-target effects on two phytoseiid species (Neoseiulus californicus and Phytoseiulus persimilis), a parasitoid (Encarsia formosa), and two microbial BCAs (Trichoderma harzianum and Metarhizium anisopliae).

Xerophilic fungi occupy versatile environments owing to their rich arsenal helping them successfully adapt to water constraints as a result of low relative humidity, high-osmolarity, and high-salinity conditions. The general term xerophilic fungi relates to organisms that tolerate and/or require reduced water activity, while halophilic and osmophilic are applied to specialized groups that require high salt concentrations or increased osmotic pressure, respectively. Species belonging to the family Aspergillaceae, and especially those classified in Aspergillus subgenus Aspergillus (sections Restricti and Aspergillus) and Polypaecilum, are particularly enriched in the group of osmophilic and salt-tolerant filamentous fungi.
