Collected Evidence: Collected Evidence: Amphibians: Vary enclosure humidity to simulate seasonal changes in the wild using humidifiers, foggers/misters or artificial rain No evidence was captured for the effects of varying enclosure humidity to simulate seasonal changes in the wild using humidifiers, foggers/misters or artificial rain. '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%2F1863https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1863Thu, 18 Jan 2018 16:28:00 +0000Collected Evidence: Collected Evidence: Amphibians: Vary enclosure temperature to simulate seasonal changes in the wild One small, replicated study in Italy found that one of six females bred following a drop in temperature from 20-24 to 17°C, and filling of an egg laying pond. One replicated, before-and-after study in Australia that provided a pre-breeding cooling period, alongside allowing females to gain weight before the breeding period, separating sexes during the non-breeding period, providing mate choice for females and playing recorded mating calls, increased breeding success.

However, frogs given the UV boost had a significantly greater fungal load than frogs that were not UV-boosted.
