The importance of large-diameter trees in the wet tropical rainforests of Australia.
PLoS ONE, 2019 Large trees are keystone structures in many terrestrial ecosystems. They contribute disproportionately to reproduction, recruitment and succession, and influence the structure, dynamics and diversity of forests.

Rainforest conversion to monocultures favors generalist ants with large colonies
Ecosphere, 2021 The conversion of natural ecosystems to agricultural land is one of the most important drivers of biodiversity decline worldwide, particularly in the tropics.

Tropical Newton-Puiseux polynomials II [PDF]
arXiv, 2021 Tropical Newton-Puiseux polynomials defined as piece-wise linear functions with rational coefficients at the variables, play a role of tropical algebraic functions. We provide explicit formulas for tropical Newton-Puiseux polynomials being the tropical zeroes of a univariate tropical polynomial with parametric coefficients.

Rainforest refugia and Australia's Wet Tropics [PDF]
Proceedings of the Royal Society of London. Series B: Biological Sciences, 1999 Comparison of mitochondrial DNA variation among populations of three endemic lizard species in Australia's Wet Tropics rainforest reveals clear evidence of population-level response to Pleistocene rainforest contraction and subsequent expansion. This pattern is repeated in two separate rainforest regions (natural replicates), between which populations ...

Nano Select, Volume 6, Issue 5, May 2025.ABSTRACT This study examined the synthesis of zinc oxide nanoparticles (ZnONPs) with ethanolic extract from leaf and fruit of Dennettia tripetala (Class: Annonaceae) and the assessment of their biological activities. Mixing of Zn (C2H3O2)2.2H2O solution and the ethanolic extracts resulted in color change, indicating the formation of ZnONPs.

Tropical rainforest bird community structure in relation to altitude, tree species composition, and null models in the Western Ghats, India [PDF]
arXiv, 2005 Studies of species distributions on elevational gradients are essential to understand principles of community organisation as well as to conserve species in montane regions. This study examined the patterns of species richness, abundance, composition, range sizes, and distribution of rainforest birds at 14 sites along an elevational gradient (500-1400 ...

Figs and the Diversity of Tropical Rainforests [PDF]
BioScience, 2005 Abstract Ficus (Moraceae) is arguably one of the most important plant genera in lowland tropical rainforests. A brief review of tropical florulas also demonstrates that Ficus is the only ubiquitously diverse genus in lowland rainforests. Monoecious hemiepiphytic figs, constituting independent radiations in each tropical biome, make up a significant ...

People and Nature, EarlyView.Abstract Reciprocity and relationality are themes which frequently emerge with respect to human–nature associations in Indigenous groups around the world. But many hunter‐gatherers have been shown to reject systems of reciprocity, instead favouring unconditional sharing both between each other and their environment through egalitarian social structures.

People and Nature, EarlyView.Abstract Integrating diverse trees and shrubs (hereafter ‘trees’) in agricultural landscapes has emerged as a crucial nature‐based solution to the triple challenge of biodiversity loss, climate change and food security. The potential benefits of on‐farm trees for both people and nature, however, are often constrained by inadequate consideration of ...

Reproductive isolation between phylogeographic lineages scales with divergence [PDF]
arXiv, 2013 Phylogeographic studies frequently reveal multiple morphologically-cryptic lineages within species. What is yet unclear is whether such lineages represent nascent species or evolutionary ephemera. To address this question, we compare five contact zones, each of which occurs between eco-morphologically cryptic lineages of rainforest skinks from the ...
