Observation Bias in Metabarcoding

Molecular 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 ...

Prioritizing future evidence needs for marine and freshwater mammal conservation action

Animal Conservation, EarlyView.
To improve conservation practice, decisions should be informed by the available evidence on the effectiveness of conservation actions. Here, we review the comprehensiveness of this evidence base for marine and freshwater mammals. We assess the taxonomic and geographic coverage of the evidence base, identify biases and suggest priorities for future ...

Parental Age, Inbreeding and Incubation Method Influence Extremely Low Hatching Success in the Ex‐Situ Population of the Extinct in the Wild Sihek

Animal Conservation, EarlyView.
Reproductive success rates are a key parameter determining the recovery potential of ex‐situ managed threatened species, with high rates often being required to produce offspring for wild releases while ensuring ex situ population viability. Here, we quantify reproductive success rates in the Extinct in the Wild sihek (Guam kingfisher) and find ...
