Article Alert: Does #plant performance under stress explain divergent life history strategies? #AquaticBotany

My recently accepted article on how flooding and nutrient stress interact to impact the growth and biomass allocation of two wetland sedges was published in the January issue of Aquatic Botany. It ran as the first article in Volume 120B. I briefly mentioned this paper last fall, a portion of my M.S. work at UW that strived to see how seedlings of an evergreen sedge (Carex obnupta) and a fast-growing deciduous sedge (Carex stipata) differed in their growth responses to environmental stress and resource subsidy. 

A Principal Component Analysis that didn't make the final manuscript. CO = Carex obnupta; CS = Carex stipata; H = high nutrients; L = low nutrients; D = deep flooding; S = shallow flooding. 
Initially, I was following up on Ewing's 1996 paper that looked at how flooding and drying shaped survival and growth in four facultative or obligate wetland species. During my thesis days I thought the project mainly had implications for wetland restoration, but have more recently come to see that the research showed fundamental differences in the capability of each species to grow under stress. Accordingly these species had vastly different life history strategies which helped to explain their range limits and ecology during succession and following hydrologic disturbance.



The academic equivalent of seeing one's name in lights...not that glamorous, eh?
