Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Introduce legislation to control the use of hazardous substances We found no studies that evaluated the effects of introducing legislation to control the use of hazardous substances on bat populations. ‘We found no studies’ means that we have not yet found any studies that have directly evaluated 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%2F1015https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1015Fri, 20 Dec 2013 17:51:23 +0000Collected Evidence: Collected Evidence: Change effluent treatments used in agriculture and forestry We found no studies that evaluated the effects of changing the effluent treatments used in agriculture and forestry on bat populations. ‘We found no studies’ means that we have not yet found any studies that have directly evaluated this action during our systematic journal and report searches.

One study was in each of Mexico, Portugal, Germany and Columbia. COMMUNITY RESPONSE (3 STUDIES) Community composition (1 study): One replicated, site comparison study in Portugal found that farms using few or no chemicals had different compositions of bat species to farms using high chemical inputs. Richness/diversity (2 studies): One site comparison study in Mexico found that coffee agroforestry plantations using few or no chemicals had a higher diversity of insect-eating bat species than plantations with high chemical inputs, but the diversity of fruit and nectar-eating bat species did not differ. One paired sites study in Germany recorded more bat species over grassland with moderate or no fertiliser applications than grassland with high fertiliser applications. POPULATION RESPONSE (3 STUDIES) Abundance (2 studies): Two site comparison or paired sites studies (one replicated) in Portugal and Germany found that farms or grasslands with few or no chemical inputs had higher overall bat activity (relative abundance) than those using high chemical inputs. Condition (1 study): One replicated, site comparison study in Columbia found that great fruit-eating bats captured in ‘silvopastoral’ areas that used no chemicals, along with agroforestry, had higher body weights and body condition scores than those in conventional farming areas that used chemicals.

Therefore we have no evidence to indicate whether or not the intervention has any desirable or harmful effects.Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F2016https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F2016Wed, 05 Dec 2018 17:43:25 +0000
