Arboreal microclimates across Philippines elevation gradient

The dataset provides microclimate time series for climate loggers in the canopy, the understory, and inside Asplenium bird's nest ferns along an elevation gradient spanning 900 m to 1900 m on Mt. Banahaw, the Philippines. Trait characteristics were additionally collected for the ferns in which microclimate were monitored., The data were collected along an elevation gradient spanning 900 m to 1900 m a.s.l. on Mount Banahaw in southern Luzon, the Philippines. The gradient is characterized by dipterocarp and montane rainforest from 900 m to 1700 m and mossy and Pinus forest above 1700 m a.s.l.
Microclimate Data
We monitored temperature in the understory, canopy, and inside BNFs every 200 m in elevation using temperature data loggers (Maxim Hygrochron ibutton Model DS1923; http://www.maxim-ic.com/). We placed a pair of temperature loggers in four to five trees per elevation. In each tree, loggers were placed in the upper canopy, which varied across elevations and transects from an average of 11.75 m to 18.75 m, and directly below, suspended 1 m above the ground (hereafter ‘understory’). Paired canopy-understory loggers were separated by a minimum of 100 m to reduce spatial autocorrelation.
Along two 50 m transects at each elevation from 900 m to 1700 m, we quantified the abundance and the vertical distributio..., , # Asplenium bird's nest fern microclimates

## Description of the data and file structure

Microclimate data were collected in the canopy, understory, and inside Asplenium bird's nest ferns (BNFs) to understand the extent to which BNFs buffer microclimates across an elevation gradient. Additionally, BNF characteristics were collected to determine if BNF morphology influences microclimate buffering capacity.
