Article
The probability of stem survival after fire is strongly influenced by energy allocation to bark because bark thickness affects heat transfer during fire. Greater relative investment in inner bark versus outer bark should also enhance survival because of greater moisture content of inner bark. We measured stem diameter, bark thickness, and habitat p...
Article
In resprouting species, fire-induced topkill causes a reduction in height and leaf area without a comparable reduction in the size of the root system, which should lead to an increase in the efficiency of water transport after fire. However, large plants undergo a greater relative reduction in size, compared with small plants, so we hypothesized th...
Article
Plant species distributions and transitions between vegetation types are determined by numerous factors, including disturbances such as fire. Documentation of past changes in the distribution and structure of fire-dependent ecosystems is necessary to assess the success of land management in maintaining historic vegetation types. In our study system...
Conference Paper
Background/Question/Methods Species that resprout after fire undergo a reduction in height and leaf area after fire without a comparable reduction in the size of the root system, and this reduction is likely to be greater for larger-statured species. An increase in the root:shoot biomass ratio post-fire should lead to an increase in the efficienc...
Conference Paper
Background/Question/Methods Nitrogen deposition can strongly influence carbon and nitrogen cycling in forest ecosystems. Studies using N additions have shown that carbon sequestration in soil organic matter can increase due to lower soil respiration. We tested this hypothesis along an existing N availability gradient in the southern Appalachian M...

... The code of each hybrid taxa is explained in the text cork cambium, or rhytidome). The amount of outer bark in a stem is associated with protection from fire and other factors, including pathogens (Graves et al. 2014;Schafer et al. 2015;Rosell 2016) and with bark photosynthesis (Rosell et al. 2015). ...
... Elevation ranges from 43 to 176 m. The landscape at Fort Bragg has been divided into discrete burn compartments of which one-third burn annually ( Schafer et al., 2013), approximating the estimated, historic mean fire frequency (2.2 years) of longleaf pine savannas ( Stambaugh et al., 2011). Prescribed fires are started in the upland savanna and allowed to burn downslope towards wetland ( Lashley et al., 2014). ...
... It is common in many vegetation communities worldwide and enables the successful survival of plants after disturbance (Mostacedo et al. 2009, Pausas and Keeley 2014, Zeppel et al. 2015, Pausas et al. 2016, Yao et al. 2021c). In resprouting species, the water absorbed by roots is transported to less aboveground leaf area, which improves tissue water status and gas exchange at the early post-disturbance stage (Utsumi et al. 2010, Ramirez et al. 2012, Nolan et al. 2014, Schafer et al. 2014. The superior performance of younger resprouts relative to their more mature counterparts is usually associated with their higher stem hydraulic conductivity (Genet et al. 2010, Fang et al. 2013, Schafer et al. 2014, Gričar et al. 2020. ...
