Aquatic entomology is the study of insects that inhabit aquatic environments, including freshwater and marine ecosystems. This field examines the biology, ecology, behavior, and interactions of aquatic insects, contributing to our understanding of biodiversity, ecosystem health, and the roles these organisms play in aquatic food webs.

Key research themes

1. How does anthropogenic activity, including biomonitoring, impact aquatic insect populations and biodiversity?

This research area investigates the direct and indirect effects of human interventions such as environmental monitoring protocols, land use changes, and pollution on the mortality, population dynamics, and biodiversity of aquatic insects. It addresses ethical and conservation concerns related to sampling-induced mortality and broader environmental degradation that threaten insect populations, which are vital for aquatic ecosystem functioning.

Key finding: Analyzing extensive biomonitoring data in Poland, the study found that 83-95% of over 8.8 million collected aquatic insects die unnecessarily due to sub-sampling procedures, with mortality rates varying up to 30-fold between... Read more
Key finding: This work highlights that the common use of non-selective bulk sampling and excessive subsampling in freshwater biomonitoring causes steep mortality of aquatic invertebrates—often many thousands per sample—which surpasses... Read more
Key finding: From a broad entomological perspective, the research identifies the global decline of insect populations, accelerated habitat degradation, and climate change as critical challenges requiring urgently improved monitoring and... Read more

2. How do aquatic insect emergences and landscape hydrography interact to influence terrestrial and aquatic ecosystem dynamics?

This theme encompasses the spatial-temporal distribution of emerging aquatic insects across diverse aquatic habitats, their dispersal into terrestrial ecosystems, and how hydrographic mapping and landscape features modulate these processes. Understanding hydrographic complexity and insect emergence patterns is crucial for unraveling subsidies from aquatic to terrestrial food webs and effectively managing ecosystem connectivity.

Key finding: The study quantitatively linked aquatic insect (Ephemeroptera, Plecoptera, Trichoptera, Megaloptera) abundance to dynamically mapped hydrographic networks in a temperate agricultural landscape in Brittany, France. By... Read more
Key finding: Through comparative analysis of sampling methodologies in neotropical streams, the work identified effective methods for collecting benthic macroinvertebrates and freshwater crabs. It underscored the importance of appropriate... Read more

3. What roles do aquatic insects and associated parasites play in freshwater ecosystems and aquaculture, and how can parasitological insights inform sustainable management?

Research here explores the diversity and ecological significance of aquatic insects as well as the diversity of their parasites in freshwater ecosystems and aquaculture environments. It examines parasite impacts on host organisms, the use of parasites as biological tags for fisheries management, and the development of integrative parasitological approaches to improve fish health and sustainable production practices.

Key finding: This comprehensive review outlines the significant advances in fish parasitology over the past century, emphasizing the use of parasites as biological tags to delineate fish stocks and monitor population dynamics. It also... Read more
Key finding: The study documents the high parasite diversity infecting nine freshwater fish species, identifying 26 parasite taxa including protozoans, trematodes, and monogeneans, and associates parasite prevalence with potential... Read more
