Table 1. Abbreviated Dataset A - Pyrodiversity and Specific Forest Characteristics, grouped by Island ID Code
Table 2. Abbreviated Dataset B - ARU and Sampling Period Environmental Parameters, grouped by Island ID Code-UTM
In this study, two primary datasets were combined and utilized for analyses. Table 1 exhibits basic pyrodiversity parameters as they relate to the associated islands they were collected upon. Table 2 is an abbreviated example of data collected from ARU's set across all sample sites and their respective variables (abundance detected, vocalization type, weather parameters, etc..). These datasets are much larger when in use, but not all variables are necessary for visualization.
This study uses a multi-variate approach due to a series of predictor variables and their delineated response variables. As such, predictor variables most often used in analyses include Time since Fire, Island Area, and Distance to Mainland. Response variables encompass all those aspects that are influenced by the above. A list of the most compelling includes Basal Area, Coarse Woody Debris (CWD) Volume, Species Detected (sp. code), Abundance, and myriad others.
All of the abiotic components are applied as metrics of habitat quality and suitability for both generalist and specialist species, and are further used to determine relationships between taxon abundance and detection rates across sites.
Exploratory Graphics
Figure 1. A top-down visualization of the spatial relationship with avian species richness detected on each island site Each island site has been assigned a circle for visualization of species richness variation. Circle size corresponds to the number (n) of species detected; the larger the circle, the greater the richness. Reference Figure 1 for corresponding Island ID's.
Figure 2. Multi-panel visualization of control and response variable interactions; a comparison of number of species detected as a function of island biogeography and pyrodiversity. Each circle represents the corresponding data point from an individual island site.
