Dear all,
The International Tree Mortality Network, an initiative of the IUFRO
task force on monitoring trends and patterns in global tree mortality,
continues the online seminar series on *March 15, 4 pm CET*, with:
*Bonaventure Ntirugulirwa*
*Title: **Mortality of Afrotropical trees in a temperature manipulation
experiment: Result from the Rwanda TREE project*
_Abstract:_ Knowledge on mortality responses of tropical trees and
communities under projected warmer climate is limited. Trees in tropical
montane forests (TMFs) are considered particularly vulnerable to climate
change, but this hypothesis remains poorly evaluated due to data
scarcity. To reduce the knowledge gap on the warming response of TMFs,
we have established a field experiment along an elevation gradient
ranging from 2400 m a.s.l. (15.2 °C mean temperature) to 1300 m a.s.l.
(20.6 °C mean temperature) in Rwanda. Twenty tree species, native to
East and Central Africa, from two forest types of origin (transitional
rainforest at 1600 – 2000 m a.s.l, and TMF at 2000 – 3000 m a.s.l.) and
two successional groups, early (ES) and late succession (LS), were
planted in multispecies plots at three sites along the gradient. Tree
growth and survival of 5400 trees was monitored regularly over two
years. The results showed that ES trees from lower elevations grew
faster at warmer sites while several of the LS species, especially from
higher elevations, did not respond or grew slower. Moreover, tree
mortality increased in a warmer climate and this was more pronounced in
high-elevation and LS species compared to lower-elevation and ES tree
species. ES species with transitional rainforest origin strongly
increased in proportion of stand basal area at warmer sites, while
tropical montane forest species declined, suggesting that
higher-elevation and LS species are at risk to be outcompeted by
lower-elevation and ES species in a warmer climate. We conclude that
tree mortality and growth responses combined may lead to modified tree
community composition in a warmer climate, favouring lower-elevation and
ES tree species. This has important implications for biodiversity and
carbon storage of Afromontane forests.
_Bio:_ Bonaventure Ntirugulirwa is a research fellow in the Forest
Productivity and Improvement Program at the Rwanda Forestry Authority of
the Ministry of Environment in Rwanda. He is a PhD candidate at the
University of Rwanda and at the University of Gothenburg in Sweden. His
research focus are native tree species, their relation to ecological
regions, and the influence of climate change on growth and mortality.
