Towards evidence-based conservation of subterranean ecosystems.

Article Synopsis
- - Subterranean ecosystems are vast and crucial to biodiversity but largely neglected in conservation efforts, prompting the designation of 2021 and 2022 as International Years of Caves and Karst to raise awareness of their importance.
- - A systematic review of 708 publications from 1964 to 2021 revealed a significant rise in subterranean research since the 2000s, yet the fraction of studies effectively assessing conservation intervention impacts has dwindled.
- - Findings showed that 31% of interventions were statistically tested for effectiveness, with research heavily focused on certain areas and organisms, indicating a need for more rigorous quantitative assessments to better understand and improve conservation strategies in subterranean ecosystems.
In this paper, we redescribe six species of the genus Ilyodromus Sars, 1894: I, stanleyanus (King, 1855), I. varrovillius (King, 1855), I. smaragdinus Sars, 1894, I.

Methodology/principal Findings: We used DNA sequences from the mitochondrial COI gene and the nuclear ITS2 region to check species boundaries according to the evolutionary genetic (EG) species concept in five morphospecies in the putative ancient asexual ostracod genera, Penthesilenula and Darwinula, from different continents.
The copepod family Centropagidae is widely distributed and occurs in marine, estuarine, freshwater, and inland saline settings. Molecular phylogenies based upon the 16S and 28S genes demonstrate a complex biogeographic history, involving at least five independent invasions of continental waters from the sea. The first colonization was ancient, likely into part of Gondwanaland, and resulted in an inland radiation in southern genera via both vicariance and subsequent habitat shifting among different types of continental waters.
