Gatun Lake Islands
Basic information
Sample name: Gatun Lake Islands

Reference: G. H. Adler. 2000. Tropical tree diversity, forest structure and the demography of a frugivorous rodent, the spiny rat (Proechimys semispinosus). Journal of Zoology 250:57-74 [ER 2483]
Geography
Country: Panama

Coordinate: 9° 11' N, 79° 53' W
Basis of coordinate: based on nearby landmark
Geography comments: eight islands within Gatun Lake "all of roughly similar size (1.7± 3.5 ha) and isolation (30±152 m from other land masses harbouring P. semispinosus)... All islands were located within a 40-km2 area"
coordinate based on Gatun Lake
elevation is for the surface of the lake and is from Kenoyer (1929, Ecology)
Climate and habitat
Habitat: tropical/subtropical moist broadleaf forest
Altered habitat: fragment
Substrate: ground surface
MAT: 27.0
MAP: 2612.0
Habitat comments: "tropical moist forest" that in most cases has been "regenerating since 1914" and is therefore old secondary forest
MAP is for central Panama; MAT is for the BCI area and is based on many sources, some of which report 26º and most of which report 27º
Methods
Life forms: trees
Sites: 8
Site area: 18.200
Sampling methods: no design
Sample size: 12976
Years: 1991
Minimum size: 10.0cm dbh
Basal area: total is 538.8000
Sampling comments: island areas are 1.9, 1.7, 2.7, 2.1, 1.8, 2.4, 3.1, and 2.5 ha
basal area figures in table 4 are in units of m2 per "100-m2 "circle" at each of 470 stations scattered across the islands, with the number of stations per island not stated
based on the reported mean number of trees per station, the basal figures are too high for the units to be correct, and I am reasonably confident they are off by exactly one order of magnitude
total BA has therefore been back computed from these figures plus the area figures and divided by 10
