Collected Evidence: Collected Evidence: Use temperature treatment to reduce chytridiomycosis infection Four of five studies (including four replicated, controlled studies) in Australia, Switzerland and the USA found that increasing enclosure or water temperature to 30–37°C for over 16 hours cured frogs and toads of chytridiomycosis. One found that heat treatment at 30–35°C for 36 hours did not cure northern leopard frogs.  Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F770https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F770Mon, 19 Aug 2013 16:15:16 +0100Collected Evidence: Collected Evidence: Use signs and access restrictions to reduce disturbance We found no evidence for the effects of using signs and access restrictions to reduce disturbance on amphibian populations. '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%2F795https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F795Thu, 22 Aug 2013 14:38:56 +0100Collected Evidence: Collected Evidence: Use zooplankton to remove zoospores We found no evidence for the effects of using zooplankton to remove chytrid zoospores on amphibian populations.
