	abstract = {Grass populations in tropical savannas are highly resilient in relation to different fire regimes, but the
mechanisms conferring such resilience have been poorly studied. Here we examine one such mechanism, high adult
survival during fire, for three perennial grass species in an Australian savanna: Eriachne triseta Nees ex Steud,
Eriachne avenacea R.Br and Chrysopogon latifolius S.T.Blake.The study examined survivorship after 3 years, at plots
subject to experimental fire regimes (experiencing 0, 1, 2 or 3 fires over the study period) at theTerritory Wildlife
Park near Darwin in the Northern Territory, Australia. Mean survivorship was 79.9\%, 64.3\% and 62.0\% for E.
avenacea, E. triseta and C. latifolius respectively. For the two species of Eriachne, mean survivorship was highest (E.
avenacea, 94.6\%; E. triseta, 77.1\%) in unburnt plots, whereas survivorship of C. latifolius was highest (71.7\%) under
highest fire frequency. However, variation in survivorship among fire regime treatments was not statistically
significant for any of the study species. This negligible difference in survivorship among regimes points to fire
tolerance (sprouting ability) as an important mechanism contributing to the resilience and persistence of perennial
grasses in these savannas.},

	abstract = {Environmental features associated with the distribution of grass species are poorly known in tropical savannas, particularly at smaller spatial scales. The present study aimed to determine the relative influence of 11 environmental characteristics on grass-species composition in a savanna woodland in northern Australia. Environmental characteristics relating to woody-vegetation structure and soil, plus the long-term (14-year) fire frequency, were documented along an environmental gradient and compared with grass-species composition. Differences in grass-species composition, as well as richness and evenness, were related to differences in vegetation structure and edaphic characteristics. In particular, grass-species composition was most strongly related to plant-available moisture, the density of woody plants in the midstorey (2.0{\textendash}9.99 m height), and canopy and litter cover. Grass-species richness and evenness were extremely low in areas where midstorey density, canopy cover and litter cover were high, and where soil moisture content in the root zone of grasses was low. Differences in fire frequency also influenced grass-species composition, with areas that had experienced lower fire frequency during the previous 14 years having lower density of the annual grass Sorghum intrans (F.Muell. ex Benth.) and the perennial grass Heteropogon triticeus (R.Br.) Stapf, and increased dominance of the perennial Eriachne triseta Nees ex Steud. The results of the present study demonstrate a complex interplay between bottom-up environmental factors and top-down processes such as fire, as determinants of grass-species composition in tropical savannas},
