Article Reference A comparison of gene flow estimates based on private allele frequencies.
The frequency of private alleles is often used to assess the amount of gene flow (Nm) between populations, with the equations proposed by SLATKIN (1985b) and by SLATKIN and BARTON (1989). Although these equations express the same relationship, they may yield different estimates of gene flow for the same data. These differences increase with decreasing frequencies of private alleles. Comparisons of Nm estimates, based on different equations can therefore be misleading. It is advisable to use these equations method only to distinguish between Nm > 1 and Nm < 1.

Article Reference A comparison of three main scientific literature databases using a search in aquatic ecology
Online searches for relevant scientific references using keywords have become common practice. Several multidisciplinary scientific online databases are available, of which Web of Science, Scopus (both payable) and Google Scholar (free of charge) are the most commonly used. We test the hypothesis that results of highly similar searches in these three databases do not necessarily give comparable results. We set out to query the three databases with a real example on “diapause in microcrustaceans” (Cladocera, Copepoda and Ostracoda), using the same time period (2012–2021), the same keywords with the same syntaxis and the same sorting criterion (“relevance”), and compared the first 100 hits provided by each database. There were several references provided which were irrelevant to the search, especially in the Web of Science, and of the remaining relevant references, only 9.84% were provided by all three databases. Our survey showed significant differences amongst the results provided by the databases, especially for “hydroperiod” and “type of environment”. These differences can be the result of different coverage of the scientific literature by the databases, but also of the different ways by which the criterion “relevance” is calculated by the three algorithms. We, therefore, recommend that literature surveys must be based on several databases; otherwise, the results might become biased.

Article Reference A distinct island population of threatened freshwater fish: to split or lump?
Freshwater fishes in the Balkans display high percentages of endemic species, many being limited to restricted distributions. Their management, for example, through identification of priority areas for conservation or through re-introduction, is hampered by a poor understanding of their taxonomic diversity and interrelationships. We evaluate the identity of a sand goby belonging to Knipowitschia, limited to a single wetland on the Greek island of Zakynthos. Its representatives morphologically differ sufficiently from their congeners to qualify as a separate species. However, in view of the similarity in mitochondrial ribosomal DNA sequences, the evolutionary plasticity of said morphological characters, and in the absence of a taxonomic revision of the Ionian Ecoregion’s Knipowitschia gobies, describing it as a new species seems unjustified and premature. Rather, we advocate that its unique habitus and its vulnerability as the island’s only resident freshwater fish necessitate conservation efforts as a kind of ‘‘phenotypically significant unit’’. We also propose sand gobies as flagships for wetlands in the region. This case study suggests a possible approach for fish conservation prioritization in the region, taking a precautionary angle in order to avoid taxonomic inflation, which is an imminent risk given the importance of nominal species and endemics in conservation policy.
