Yenziwe Mbuyisa<\/a>, a M.Sc. candidate, is looking at the water use efficiency of different Eucalyptus<\/em> clones using stable isotopes. This project is a collaborative effort between EucXylo<\/span><\/strong>\u00a0and the Global Change Biology Group (GCBG)<\/a>\u00a0under the supervision of Prof. Guy Midgley<\/a> and Prof. Dave Drew<\/a>.<\/p><\/blockquote>\n

The opportunity of climate change mitigation through global tree afforestation\/reforestation programs has become the flavour of the decade. With the likelihood of increasingly frequent and severe droughts and heat waves being a major cause for concern, understanding how trees respond to temperature extremes and limited water availability is critical to forecasting both short and long-term impacts of climate change on forest systems in South Africa.<\/p>\n

This study will evaluate the effects of ambient air temperature in concert with available water availability on the water use efficiency (WUE), physiology, and isotopic discrimination of two Myrtacae species; Eucalyptus grandis <\/em>(a species originally from New South Wales) and\u00a0Syzygium guineense <\/em> \u00a0<\/em>(a local species found predominantly in the eastern parts of South Africa). Currently, the trees have been placed in a high tunnel structure where they are exposed to a temperature gradient stimulated by a built-in wet wall. Two water treatments will be applied to the trees to help determine whether WUE varies between the two species under different temperatures and whether \u03b413<\/sup>C can be used as a reliable signal of historic WUE.<\/p>\n

After transplantation the samples were placed in a shade netted nursery where they received light frequent above-head irrigation for 8 weeks (1). Thereafter, they were moved outside to the patchy canopy of some other eucalypts for 2 weeks (2). The samples are now acclimatizing to the conditions in the tunnel (3,4) before we can initiate the treatments and collect data.<\/p>\n

Looking forward to start understanding how these two Myrtacae species will respond to predicted temperature variability and varying water availability.<\/p><\/blockquote>\n
