Filter no more: A modified plankton sampler for rapid in‐water eDNA capture

open access: yesMethods in Ecology and Evolution, Volume 15, Issue 1, Page 60-68, January 2024.
Abstract The combination of an efficient sampling method and high‐throughput analysis of environmental DNA (eDNA) can be a powerful approach for characterising biodiversity across aquatic ecosystems. Plankton net tows are one of the oldest, simplest, and least expensive methods for seston and eDNA collection, but require laborious filtration steps ...

Failure of isoxsuprine HCl to increase sheep fertility after cervical versus laparoscopic AI using chilled semen at different durations

open access: yesAnimal Science Journal, Volume 95, Issue 1, January/December 2024.
Abstract To improve the fertility of cervical artificial insemination (AI) in sheep, we investigated isoxsuprine HCl usage on the cervical passage during cervical AI. We also compared cervical and laparoscopic AI fertility results of using chilled semen at different durations.
