Drivers of Anuran Assemblage Structure in a Subtropical Montane Region

open access: yesEcology and Evolution, Volume 14, Issue 12, December 2024.
Montane regions are known for high biodiversity and environmental conditions. Here, we investigated how these conditions influence frog diversity. Specifically, we tested whether frog richness, abundance, and composition are related to temperature and productivity between lowlands and highlands.

Transitions Into Freezing Environments Linked With Shifts in Phylogenetic Integration Between Vitaceae Leaf Traits

open access: yesEcology and Evolution, Volume 14, Issue 11, November 2024.
ABSTRACT Understanding how the intrinsic ability of populations and species to meet shifting selective demands shapes evolutionary patterns over both short and long timescales is a major question in biology. One major axis of evolutionary flexibility can be measured by phenotypic integration and modularity.

The non‐flowering plants of a near‐polar forest in East Gondwana, Tasmania, Australia, during the Early Eocene Climatic Optimum

open access: yesAmerican Journal of Botany, Volume 111, Issue 9, September 2024.
Abstract Premise The Cenozoic Macquarie Harbour Formation (MHF) hosts one of the oldest and southernmost post‐Cretaceous fossil plant assemblages in Australia. Coinciding with the Early Eocene Climatic Optimum (EECO) and predating the breakup of Australia from Antarctica, it offers critical data to study the diversity and extent of the Austral Polar ...

Numerical Simulation of Spacecraft Charging Attributed to Ionospheric Plasma in Polar and Equatorial Environment

open access: yesIndonesian Journal of Geography, 2020
The presence of spacecraft in ionospheric plasma can change plasma properties, vice versa plasma can lead to charge buildup on spacecraft. The level of charging, through electric potential of spacecraft, initially depends on plasma density.
