Verified Papers

Hatching Plasticity in Captive-Bred Pickersgill's Reed Frog

Zoo Biology (2025): shows disturbance can shift hatching timing, with lower survival in disturbed clutches by day 30. Practical implication: reduce clutch disturbance in captive workflows.

Developmental Life Stages in Ex-Situ Pickersgill's Reed Frog

Zoo Biology (2022): defines seven developmental stages under captive conditions and provides timing references for conservation breeding and release support.

Collaborating for Conservation: First Five Years of the Biodiversity Management Plan

African Biodiversity and Conservation (2025): reports coordinated implementation outcomes for Pickersgill's reed frog conservation under a multi-partner management framework.
