Greenhouse mixed culture experiment from August 2002 to April 2003 (FCE): Evaluate the effect of salinity and hydroperiod on interspecific mangrove seedlings growth rate (mixed culture) / Morphometric variables
A greenhouse experiment (mixed culture experiment) was performed for 8 months to evaluate the effect of salinity and hydroperiod on seedling growth rates of 2 mangrove species( Laguncularia racemosa and Rizhophora mangle). Data analyses are currently being performed.
Consequences of intraspecific and interspecific biodiversity in willows and poplars: Tree growth and herbivory
Research addressing the relationship between biodiversity and ecosystem function abounds (Balvanera et al. 2006; Cardinale et al. 2012) though most researchers have focused on the effects of either intraspecific or interspecific diversity on ecological function. Research at Cedar Creek and elsewhere has documented associations between species diversity (?interspecific diversity?), species interactions and many ecological functions, including primary productivity, nutrient cycling, soil and water quality, ecosystem stability, and resistance to invasion. (Tilman et al. 1996; Symstad et al. 2003; Hooper et al. 2005; Balvanera et al. 2006; Quijas et al. 2010) In parallel, research in systems such as goldenrod (Crutsinger et al. 2006, 2008a,b, 2009; Souza et al. 2011) and poplar (Schweitzer et al. 2004, 2008; Bailey et al. 2005; Madritch et al. 2009; Fischer et al. 2010; Courty et al. 2011; Lowejewski et al. 2012; Robinson et al. 2012), among others, has demonstrated the relationship between genotypic diversity (?intraspecific diversity?) and a similar group of functions that include primary productivity; nutrient cycling; resistance to invasion; ecosystem stability; microbial, epiphyte, and arthropod community diversity; litter decomposition; and fungal endophyte and mycorrhizal associations. Taken together, these two discourses suggest that interspecific and intraspecific diversity jointly drive species interactions and structure ecosystem processes including primary productivity, nutrient dynamics, resistance to and resilience following disturbance. Yet the relative roles of intraspecific versus interspecific diversity in structuring these processes remain uncharacterized. Several groups of investigators have explored the consequences for ecological function of varying intraspecific diversity of a focal species and interspecific diversity of its surrounding community (Booth and Grime 2003; Cook-Patton, et al. 2011; Hargrave et al. 2011; Whitlock et al. 2011; Chang et
Data from: Interspecific variation in post-disturbance growth responses of a savanna tree community and its implications for escaping the fire trap
<p>Vegetation states in savannas are highly sensitive to tree growth rates, which determine whether individual trees can 'escape' periodic disturbances. Resprouting trees have lopsided shoot:root ratios and are often multi-stemmed, and these variables can modify post-disturbance growth rates and therefore the probability of escape. To date, few studies have systematically examined the implications of interspecific variation in these factors for escape. We conducted a two-year field experiment in lowveld savanna in South Africa and quantified post-disturbance growth characteristics of topkilled trees among 16 species. We examined the dependence of growth on pre-disturbance stem size across species, and the relationship between growth rates and the tendency of trees to produce a few large <i>vs.</i> many small resprouts following disturbance. We found that resprout growth was strongly influenced by pre-disturbance size, but the relationship did not vary among species. In contrast, our results showed that fast-growing species tend to allocate resources towards a few dominant stems, while slow-growing species allocated new biomass towards many smaller stems. Tree species that produced a few large stems also tended to produce individual stems that were tall and thin, further suggesting that the "few large <i>vs.</i> many small" axis is linked to intrinsic species attributes. These findings have implications for understanding how interspecific variation in savanna tree communities may influence their ability to escape disturbance traps.</p>
