Tropical plant species are expected to have high heat tolerance reflecting phenotypic adjustments warm regions or their evolutionary adaptation history. However, tropical highland specialists adapted the colder temperatures found in highlands, where short and prostrated vegetation decouples plants from ambient conditions, could exhibit different upper thermal limits than those of lowland counterparts. Here we evaluated leaf 21 alpine paramo determine: 1) whether with restricted distribution...
Páramos, tropical alpine ecosystems, host one of the world’s most diverse floras, account for largest water reservoirs in Andes, and some soil carbon pools worldwide. It is global importance to understand future this extremely carbon-rich ecosystem a warmer world its role on climate feedbacks. This study presents result first situ warming experiment two Colombian páramos using Open-Top Chambers. We evaluated response several balance-related processes, including decomposition, respiration,...
The protocol is based on Krause (2010) with some modifications proposed by the Feeley Lab in 2016. This for finding heat tolerance or critical thermal maximum temperature of plant leaves. Plants can undergo damage that be repaired as long value not exceed. called (CTmax) (T50) and highest a leaf take before irreversible occurs, when exceeded leads to necrosis. way we measure this using chlorophyll fluorescence, more specifically, efficiency PSII Fv/Fm, which optimal values are around 0.83...
