Collected Evidence: Collected Evidence: Amphibians: Vary food provision to reflect seasonal availability in the wild No evidence was captured for the effects of varying food provision to reflect seasonal availability in the wild. 'No evidence' for an action means we have not yet found any studies that directly and quantitatively tested this action during our systematic journal and report searches. Therefore we have been unable to assess whether or not the action is effective or has any harmful impacts. Please get in touch if you know of such a study for this action.Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1883https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1883Fri, 19 Jan 2018 13:51:52 +0000Collected Evidence: Collected Evidence: Amphibians: Formulate adult diet to reflect nutritional composition of wild foods No evidence was captured for the effects of formulating diet to reflect nutritional composition of wild foods.
