A Comprehensive Evaluation of Taxonomic Classifiers in Marine Vertebrate eDNA Studies

open access: yesMolecular Ecology Resources, EarlyView.
ABSTRACT Environmental DNA (eDNA) metabarcoding is a widely used tool for surveying marine vertebrate biodiversity. To this end, many computational tools have been released and a plethora of bioinformatic approaches are used for eDNA‐based community composition analysis.

Nyctereutes terblanchei: The raccoon dog that never was [PDF]

open access: yes, 2012
Fossils of the raccoon dog (genus Nyctereutes) are particularly rare in the African PlioPleistocene record, whilst the sole living representative, Nyctereutes procyonoides, is found in eastern Asia and parts of Europe. In southern Africa, only one fossil

Arrhinolemur scalabrinii Ameghino, 1898, of the late Miocene : a taxonomic journey from the Mammalia to the Anostomidae (Ostariophysi: Characiformes)

open access: yesNeotropical Ichthyology
The fossil species Arrhinolemur scalabrinii, which was described from late Miocene deposits of Entre Ríos, Argentina, is reevaluated. Whereas the species was originally placed in the Primates (Mammalia) and later made the unique member of the order ...

Observation Bias in Metabarcoding

open access: yesMolecular Ecology Resources, EarlyView.
ABSTRACT DNA metabarcoding is subject to observation bias associated with PCR and sequencing, which can result in observed read proportions differing from actual species proportions in the DNA extract. Here, we amplify and sequence a mock community of known composition containing marine fishes and cetaceans using four different primer sets and a ...

Mouse genome engineering uncovers 18 genes dispensable for male reproduction

open access: yesAndrology, EarlyView.
Abstract Background Male infertility is an intricate multifactorial disease involving the interplay between genetic and environmental factors. Genetic anomalies account for more than 15% of all male infertility cases; however, diagnosing them exhibits enormous challenges due to variable symptomatic presentations and limited knowledge of gene functions.
