Country: Peru

Coordinate: 12° 47' 21" S, 71° 23' 28" W
Basis of coordinate: stated in text
Geography comments: "within the Manu Biosphere Reserve"
Habitat: tropical/subtropical moist broadleaf forest
Altered habitat: secondary forest
Protection: biosphere reserve
Substrate: ground surface
Habitat comments: "The study site... consists of ∼800 ha of regenerating lowland tropical forest" and specifically "completely cleared and now regenerating forest" that was previously converted "to agriculture for coffee and cacao"; "Major human disturbance had started ∼50 years prior to the study and lasted for 20 years before systematic human disturbance activities were abandoned in the 1980s"
Life forms: frogs, salamanders
Sites: 20
Site length: 2000.000
Site width: 4.000
Sampling methods: line transect, hand capture
Sample size: 162
Years: 2012 - 2014
Seasons: dry, wet or monsoon
Sampling comments: "Surveying was conducted through both wet and dry seasons between March 2012 and May 2014... Sixty sampling locations (each consisting of 100 m long 4 m wide transects; surveyed up to two metres in height; Folt and Reider, 2013) were established... twenty within CCR... Each transect was surveyed between 13 and 22 occasions... Individuals captured during nocturnal transects were released behind the searchers" and there were specifically 66 "samples" pertaining to CCR
