Abstract

Some species of freshwater microcrustaceans have been widely used for biological control of mosquito larval populations. These zooplankton communities play an important role against some species of mosquitoes by exerting competitive pressure or predation. However, zooplankters are scarcely studied in many Caribbean islands such as Hispaniola. The goal of this study was to improve the knowledge of these microcrustaceans in order to better understand the biodiversity and ecology of this Antillean Island. Samples of zooplankton were taken from 28 ponds in the northern Dominican Republic during 2020. The total richness of microcrustaceans was 25 species, comprising 17 copepods and 8 cladocerans. Most of the collected species were previously described for the island, and some of them are registered as potential biological controllers of mosquito larvae populations. Five genera (including 6 species) of microcrustaceans that inhabit the ponds are recorded for the first time for Hispaniola: Simocephalus Schoedler, 1858; Pleuroxus Baird, 1853; Ilyocryptus G.O. Sars, 1861; Apocyclops Lindberg, 1942; and Diacyclops Kiefer, 1927. Here, we discuss these new findings in relation to the competitive and/or predatory potential of these species against mosquito larvae. The present study improves the knowledge of biodiversity in ponds in the Dominican Republic.

伊斯帕尼奥拉岛淡水微甲壳类:新记录及其生物防治潜力

一些淡水微型鲸目动物已被广泛用于蚊子幼虫种群的生物控制。这些浮游动物群落通过施加竞争压力或捕食，对某些种类的蚊子发挥着重要作用。然而，在许多加勒比海岛屿，如伊斯帕尼奥拉岛，人们很少研究浮游动物。这项研究的目的是提高对这些微珊瑚的了解，以便更好地了解这个安的列斯岛的生物多样性和生态。2020年，从多米尼加共和国北部的28个池塘中采集了浮游动物样本。微型鲸目动物的总丰富度为25种，包括17种桡足类和8种支角类。大多数收集到的物种以前都被描述为该岛的物种，其中一些被登记为蚊子幼虫种群的潜在生物控制者。伊斯帕尼奥拉岛首次记录到栖息在池塘中的5属（包括6种）微鲸目动物：Simocephalus Schoedler，1858；Pleuroxus Baird，1853年；Ilyocryptus G.O.Sars，1861年；Apocops Lindberg，1942年；和Diacyclops Kiefer，1927年。在这里，我们讨论这些新发现与这些物种对蚊子幼虫的竞争和/或掠夺潜力有关。本研究增进了对多米尼加共和国池塘生物多样性的了解。

期刊介绍： Limnetica publishes original research articles on the ecology of inland waters. The scope of Limnetica includes the ecology of rivers, lakes, reservoirs, coastal lagoons and wetlands, as well as biogeochemistry, paleolimnology, development of new methodologies, taxonomy, biogeography and any aspect of theoretical and applied continental aquatic ecology such as management and conservation, impact assessment, ecotoxicology and pollution. Limnetica will accept for its publication scientific articles presenting advances in knowledge or technological development, as well as as papers derived from new practical approaches on the topics covered by the journal.
