Methodology

Methods: 

Bromeliads were collected from each of the three forest types and separated into four components: live bromeliad tissue, and coarse, medium and fine debris. Sampling units were individual bromeliads, which were collected and dismantled leaf by leaf to obtain contents.Samples of each component were oven-dried t 105 °C for at least 24 h and ground with a Wiley mill. The ground material was analysed for phosphorus, potassium, calcium and magnesium using a Beckman plasma emission spectrometer Spectra Span V) after a digestion in concentrated HNO3 and 30% H2O2 (Luh Huang & Schulte 1985). Nitrogen, carbon and sulphur were analysed using a LECO CNS-2000 and the dry combustion method (Tabatabai & Bremmer 1991). Precision for all analyses was assured by running samples of known chemical composition every 40 samples.The ground material was analysed for phosphorus, potassium, calcium and magnesium using a Beckman plasma emission spectrometer (Spectra Span V) after a digestion in concentrated HNO3 and 30% H2O2 (Luh Huang & Schulte 1985).
