AbstractTropical forests are responsible for about half of the terrestrial gross primary productivity on Earth. However, rising temperatures and droughts, including those intensified by El Niño Southern Oscillation (ENSO), are affecting many tropical forests in Central America. ENSO droughts have historically been associated with increased canopy tree death in the tropics, affecting community structure and biogeochemical cycles. Hydraulic safety margins, ie how much plants buffer themselves from the risk of hydraulic failure, may be sensitive to ENSO droughts. We investigated the effect of the 2015-2016 ENSO on 18 dominant canopy trees across two sites with differing precipitation on the isthmus of Panama and asked,'Do hydraulic safety margins vary across a tropical rainfall gradient?'
