The Use of Environmental DNA as Preliminary Description of Invertebrate Diversity in Three Sicilian Lakes

Animals, Journal Year: 2025, Volume and Issue: 15(3), P. 355 - 355

Published: Jan. 26, 2025

Freshwater ecosystems are among the most severely affected environments by species loss caused climate change and intense anthropogenic pressure. To preserve biodiversity, biomonitoring plays a key role providing reliable data on biological diversity ecological status. Environmental DNA (eDNA) metabarcoding has emerged as powerful non-invasive alternative to traditional morphology-based sampling identification methods. This study represents first application of eDNA analysis assess invertebrate communities in three Sicilian Lakes: Poma, Piana degli Albanesi Scanzano. Water samples were collected at two points each lake after filtration with nitrocellulose membranes, was extracted performed. A total 27 identified, belonging Phyla Annelida, Arthropoda Rotifera. Notably, revealed presence alien (Daphnia parvula Acanthocyclops americanus), dangerous associated transmission viral diseases (Culex pipiens), potential new records for Sicily (Stylaria lacustris, Platypalpus exilis, Pammene aurana, Limnephilus rhombicus). These results provide preliminary snapshot biodiversity these sites, demonstrating how complement, but not replace, methods, contributing assessment ecosystem

Water fleas (Crustacea: Cladocera) are recently regarded as models for phylogeographic studies, but most such publications concerned the planktonic genera, first of all, Daphnia O.F. Müller. The aim our article is to study pattern a very common littoral chydorid Pleuroxus truncatus (O.F. Müller) based on sequences two mitochondrial (cytochrome oxidase (COI) and 16S) nuclear (18S 28S) genes. All totality could be subdivided into major clades, A, having predominantly European distribution with single exclusion, B, Asian distribution, few populations in Russia; clade B three subclades (B1–B3) moderate support. Earlier derived phylogroups (subclades B1 B2) distributed south portion Western Siberia. This known previously studied daphniids. Estimations (A B) subclade differentiation time P. different methods lie interval ca . 0.01–0.3 Mya.

History of Colonization of Jeju Island (Republic of Korea) by the Water Fleas (Crustacea: Cladocera) Is Reflected by the Seasonal Changes in Their Fauna and Species Associations

The aim of this paper is to study the species composition, structure and seasonal dynamics cladoceran fauna associations in inland water bodies Jeju Island (Republic Korea). Only 47 taxa were found 199 samples. Such faunal paucity could be explained by existence only a few types aquatic environments on as compared continental China Far East Russia, with their great diversity types.

Substantial unrealised global biodiversity of continental microcrustaceans

Journal of Plankton Research, Journal Year: 2024, Volume and Issue: 46(3), P. 338 - 347

Published: May 1, 2024

Abstract Freshwater ecosystems provide essential services for human well-being, with their conservation success reliant on the precise quantification of biodiversity. Diplostraca (= Cladocera) and Copepoda are diverse groups microcrustaceans in aquatic ecosystems, important a multitude these services. We examined biodiversity trends groups, utilizing comprehensive dataset, approximately 2341 studies, spanning from early 19th Century to present day, aiming at predicting total number microcrustacean species that will have been described by 2100. Descriptions increased until 1900s, surged, then declined after 1975. The predictive models indicate year 2100, an additional 16–68% cladoceran 37–126% copepod likely be identified, representing significant portion currently unrealised Eighteen prolific authors contributed quarter descriptions, rest spread among numerous authorities. Based our extrapolation, could potentially exceed 6114 2050 9046 notwithstanding extinctions. These findings, which point amount biodiversity, underscore need refine estimates beyond conventional expert opinion. Such accuracy is crucial addressing underappreciated scale current crisis.
