“…Within each of these categories, there is great variation in soil properties and floristic composition, but these habitat differences are rarely reported. Edaphic characteristics, such as soil nutrient concentration and texture, have been shown to significantly affect the distributions of many plant groups, such as ferns and lycophytes (“pteridophytes”), palms (Arecaceae), and some shrub and tree families like Melastomataceae and Burseraceae (Cárdenas et al, 2007; Fine et al, 2005; Rodríguez et al, 2003; Ruokolainen et al, 2007; Salovaara et al, 2004; Suominen et al, 2013; Tuomisto, Poulsen, et al, 2003; Tuomisto, Ruokolainen, Aguilar, et al, 2003; Tuomisto, Ruokolainen, Yli‐Halla, 2003; Tuomisto & Ruokolainen, 2005; Vásquez & Phillips, 2000; Vormisto et al, 2004).…”
