Habitat and fire heterogeneity explain the co-occurrence of congeneric resprouter and reseeder Hypericum spp. along a Florida pine savanna ecocline

Abstract: The distribution of resprouting and reseeding woody plants may be limited by the frequency of disturbances. Such species have a high probability of persisting in frequently and rarely disturbed habitats and may co-occur at intermediate disturbance frequencies. Nonetheless, resprouters and reseeders of the genus Hypericum co-occur in frequently burned pine savannas of southeastern North America. We predicted that these congeners would sort along a fire frequency gradient resulting from fine scale variation in t… Show more

“…Because altered fire regimes allow for invasion of fire‐intolerant species (Klaus and Keyes , Nowacki and Abrams ), land managers should not be alarmed if they observe a reduction in populations of some of those species when fire‐maintained conditions are restored. Fire refugia at multiple spatial scales are available for non‐fire‐adapted species in the Coastal Plain (Harper , Platt , Hoctor et al , Crandall and Platt ).…”

“…). In habitats that historically experienced frequent fires, many of the native species are adapted to survive, regenerate/resprout and reproduce quickly after fire (see Crandall & Platt ). They have traits that insulate them from the heat of fires such as thick bark, protected buds, or seeds retained in cones (Bond & van Wilgen ).…”

“…There is evidence that native species are adapted to deal with environments with recurrent disturbances; this is particularly well-studied in ecosystems that experience frequent fires (reviewed by Keeley et al 2011). In habitats that historically experienced frequent fires, many of the native species are adapted to survive, regenerate/resprout and reproduce quickly after fire (see Crandall & Platt 2012). They have traits that insulate them from the heat of fires such as thick bark, protected buds, or seeds retained in cones (Bond & van Wilgen 1996).…”
