DOI: 10.1002/ece3.3821
Abstract: Abstract The KwaZulu‐Natal yellowfish (Labeobarbus natalensis) is an abundant cyprinid, endemic to KwaZulu‐Natal Province, South Africa. In this study, we developed a single‐nucleotide polymorphism (SNP) dataset from double‐digest restriction site‐associated DNA (ddRAD) sequencing of samples… read more here.

DOI: 10.1007/s00128-018-2285-9
Abstract: Although designed to control pests selectively, there is some evidence that environmental contamination by pesticides increases risks for humans and wildlife. In the present study, we evaluated biomarkers of oxidative stress in Astyanax jacuhiensis exposed… read more here.
