Overview

Research reveals climate change reduces fertility in small-spotted catshark, highlighting risks for elasmobranch species.

Key Points

  • To explore the impact of climate change on fertility in the small-spotted catshark.
  • Examined testis of small-spotted catshark for signs of infertility during elevated water temperatures in 2022
  • Utilized histology and proteomics to assess cellular health and functionality
  • Discovered degenerating sperm-producing cells in the small-spotted catshark
  • Identified cell cycle disruption, impaired DNA damage repair, and increased apoptosis due to temperature rise
