Recruitment filters in a perennial grassland: the interactive roles of fire, competitors, moisture and seed availability
Julia Zimmermann,Steven I. Higgins,Volker Grimm,John Hoffmann,Tamara Münkemüller,Tamara Münkemüller,Anja Linstädter +6 more
TL;DR: This study concludes that recruitment is not limited to above average rainfall years but triggered by events that open up the grass canopy and reduce the abundance of competitors, and shows that fire can play an important positive role in individual turnover of semi-arid perennial grass populations.
Journal ArticleDOI
Climate change and long-term fire management impacts on Australian savannas
TL;DR: A dynamic vegetation model is used, the adaptive dynamic global vegetation model (aDGVM), to project how climate change and fire management might influence future vegetation in northern Australian savannas and identifies how fire management strategies may influence grazing yield, carbon sequestration and greenhouse gas emissions.
Journal ArticleDOI
Understanding global change impacts on South African biomes using Dynamic Vegetation Models
TL;DR: In this article, the authors outline the limitations of existing DVMs and improvements required before reliable projections of global change impacts on South African biomes can be produced, including the plant types and key processes of many South African Biomes.
Journal ArticleDOI
Costs of persistence and the spread of competing seeders and sprouters
TL;DR: Existing theories of colonization ‐ persistence trade-offs do not completely describe interactions between persistent and non-persistent strategies, and the investigation of seeder and sprouter interactions suggests that sprouters will be more threatened by periods of rapid climate change because of their limited colonization ability.
Journal ArticleDOI
Defining functional biomes and monitoring their change globally
TL;DR: A new biome map and classification scheme that uses information on an index of vegetation productivity, whether the minimum of vegetation activity is in the driest or coldest part of the year, and vegetation height is proposed to provide an alternative classification scheme for comparing the biogeochemical rates of terrestrial ecosystems.
