(a): IAvH-P 9836, WC 2005-09-27-01, male, 360 mm TL, Nikolsky gonad stage 4 (fully mature). (b): IAvH-P 7026, WC 2005-09- 27-03, female, 326 mm TL, Nikolsky gonad stage 4 (fully mature). Waveforms are plotted head-positivity upwards, time on abscissa (scale bar = 1 ms), voltage on ordinate, horizontal dashed line = 0 volts. PSD were computed by 65536=point fast Fourier transform from 3s digital recordings. Amplitude on ordinate is scaled so that the peak power frequency is 0dB.

NPP Tropical Forest: Magdalena Valley, Colombia, 1970-1971, R1
This data set contains two NPP data files and one climate data file (ASCI .txt format). The NPP files contain data for above-ground biomass, litterfall, and nutrient content of above-ground vegetation, organic surface layer, and soils measured during an 18-month period in 1970 and 1971 at two contrasting tropical seasonal evergreen forests in Magdalena Valley, Colombia. The climate record provides mean monthly and annual precipitation (1951-1992) and mean monthly and annual average temperature (1970-1997) from Barranca Bermeja (7.00 N 73.80 W) near the Magdalena Valley sites.One forest stand sits atop a perched water table on a typical valley terrace. It is low in height, basal area (22 m2/ha), and above-ground biomass (18,109 g/m2), but rich in palms with a simple two-layered structure, frequent windthrows and mortality, and few older trees. The contrasting forest stand developed on a lower slope site under more advantageous soil and water conditions. Although number of stems/ha in this forest are smaller and palms less conspicuous, the slope forest shares dominant species of both forests but with taller trees and greater basal area (32 m2/ha) and above-ground biomass (32,581 g/m2). The above-ground biomass and the vegetative bioelement stores were estimated by harvesting sample trees and palms and allometric regressions.Above-ground net primary production (ANPP) is based on total litterfall accumulation, measured over a 12-15 month period (1,202 g/m2/yr for the terrace forest and 873 g/m2/yr for the slope forest), giving minimum estimates of NPP.
