Tradeoffs between height growth rate, stem persistence and maximum height among plant species in a post-fire succession

Article Abstract:

Post-fire patterns of height growth were estimated for 11 reseeding and eight resprouting species by surveying patches of known time since fire. The aim was to examine the evidence for faster height growth among shorter than taller species immediately following disturbance and to determine whether increased height growth was associated with decreased stem persistence.

Lack of ant attendance may induce compensatory plant growth

Article Abstract:

The effect of Oecophylla smaragdina ants on the arthropod community, herbivory and plant performance within a studied mangrove ant-plant protection system is presented. The results show that ants remove herbivorous arthropods more efficiently than predators but ant-colonized mangroves do not necessarily benefit from this despite the resulting decrease in herbivory.

Sprouting by semi-arid plants: testing a dichotomy and predictive traits

Article Abstract:

Sprouting was assessed for 45 species from a range of growth forms (grasses, forbs, sub-shrubs, woody shrubs and trees) from semi-arid Southeastern Australia. Differences between sprouting after clipping and burning reflected increased intensity and were related to the depths of buds below ground.
