Forest disturbance classes were based on both an analysis of canopy disturbance in a chronosequence of satellite images (1988 to 2010) and on field assessments of fire scars, charcoal, and logging debris.\n \nIn each plot, we installed five PVC collars 50 m apart. Each collar was approximately 7 cm in size and were installed so approximately 2 cm stayed belowground and 5 cm aboveground. Collars had a 10 cm diameter. After installation, all collars were left to ‘settle’ for at least a week before the first measurement.  The collar was connected to an infrared gas analyser (EGM5®) to measure the soil CO2 efflux (i.e. soil respiration). Immediately after every soil respiration measurement, both the soil temperature and humidity were measured inside and outside the collar. We also took note on the collar height. Measures were taken every month. After measuring the soil respiration, we also measured the temperature inside and outside the collar, as well as the soil moisture, the latter with the aid of a HydroSense II. \n\n","metadataDate":"2026-06-29T16:05:10","notGEMINI":true,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/data/e5f361b3-b434-4d11-9407-e5f48fe442b0","name":"Download the data","description":"Download a copy of this data","function":"download","type":"OTHER"},{"url":"https://data-package.ceh.ac.uk/sd/e5f361b3-b434-4d11-9407-e5f48fe442b0.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"pointsOfContact":[{"honorificPrefix":"Dr","familyName":"Berenguer","givenName":"Erika","organisationName":"Lancaster University","organisationIdentifier":"https://ror.org/04f2nsd36","role":"pointOfContact","email":"erikaberenguer@gmail.com","address":{"country":"UK"},"fullName":"Berenguer, E.","pointOfContact":"Lancaster University"}],"publicationDate":"2019-01-29T00:00:00.000Z","publishers":[{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"relationships":[{"relation":"http://purl.org/dc/terms/isPartOf","target":"c1c15ef1-c5a8-4777-be71-678c571080f1"}],"resourceIdentifiers":[{"code":"https://catalogue.ceh.ac.uk/id/e5f361b3-b434-4d11-9407-e5f48fe442b0"},{"code":"10.5285/e5f361b3-b434-4d11-9407-e5f48fe442b0","codeSpace":"doi"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"honorificPrefix":"Dr","familyName":"Berenguer","givenName":"Erika","organisationName":"Lancaster University","organisationIdentifier":"https://ror.org/04f2nsd36","role":"pointOfContact","email":"erikaberenguer@gmail.com","address":{"country":"UK"},"fullName":"Berenguer, E.","pointOfContact":"Lancaster University"},{"familyName":"Berenguer","givenName":"E.","organisationName":"Lancaster University","organisationIdentifier":"https://ror.org/04f2nsd36","role":"author","email":"erikaberenguer@gmail.com","nameIdentifier":"https://orcid.org/0000-0001-8157-8792","fullName":"Berenguer, E."},{"familyName":"Rossi","givenName":"L.C.","organisationName":"Universidade Estadual Paulista","role":"author","email":"lianachesinibio@gmail.com","address":{"country":"Brazil"},"fullName":"Rossi, L.C."},{"familyName":"Seixas","givenName":"M.M.M.","organisationName":"Unaffiliated","role":"author","email":"marina.seixas@gmail.com","fullName":"Seixas, M.M.M."},{"familyName":"Barlow","givenName":"J.","organisationName":"Lancaster University","organisationIdentifier":"https://ror.org/04f2nsd36","role":"author","email":"josbarlow@gmail.com","fullName":"Barlow, J."},{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"custodian","email":"info@eidc.ac.uk"}],"spatialReferenceSystems":[{"code":"http://www.opengis.net/def/crs/EPSG/0/4326","title":"WGS 84"}],"spatialRepresentationTypes":["textTable"],"spatialResolutions":[{"distance":"10","uom":"urn:ogc:def:uom:EPSG::9001"}],"temporalExtents":[{"begin":"2015-01-01","end":"2017-11-30"}],"title":"Soil respiration in human-modified forests of Eastern Amazonia","topicCategories":[{"value":"biota","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/biota"}],"topics":["http://onto.nerc.ac.uk/CEHMD/topic/12","http://onto.nerc.ac.uk/CEHMD/topic/17"],"type":"dataset","uri":"https://catalogue.ceh.ac.uk/id/e5f361b3-b434-4d11-9407-e5f48fe442b0","useConstraints":[{"value":"This resource is made available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"},{"value":"© Natural Environment Research Council","code":"copyright"}]}
