Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

open access: yesJournal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

First occurrences of Trionychidae (Testudines, Cryptodira) from the Miocene of Poland: Detailed cranial anatomy and biogeographic implications

open access: yesJournal of Anatomy, EarlyView.
Fossil finds from three Middle Miocene sites in Poland reveal the northernmost known presence of trionychid turtles in Europe, tentatively identified as Trionyx cf. vindobonensis, suggesting a warmer climate that supported thermophilic species in Central Europe during this period. Abstract Modern trionychids (Testudines, Cryptodira) have a pan‐tropical

Understanding marine biodiversity patterns and drivers: The fall of Icarus

open access: yesMarine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.
