Article Synopsis
- Global changes have altered fire regimes, affecting tree communities in both savanna and forest ecosystems across various climates.
- Fire frequency significantly impacts tree populations, with an average increase in fire occurrences leading to a 48% reduction in stem density and a 53% decrease in basal area after 50 years compared to unburned areas.
- The interaction between fire characteristics, climate (wet vs. dry seasons), and tree species traits, especially in terms of soil nutrient changes, plays a critical role in determining how tree communities respond to these fire regime shifts.
Abstract Temperature sensitivity of community-level physiological profiles (CLPPs) was examined for two semiarid soils from the southwestern United States using five different C-substrate profile microtiter plates (Biolog GN2, GP2, ECO, SFN2, and SFP2) incubated at five different temperature regimes. The CLPPs produced from all plate types were relatively unaffected by these contrasting incubation temperature regimes. Our results demonstrate the ability to detect CLPP differences between similar soils with differing physiological parameters, and these differences are relatively insensitive to incubation temperature.
