Sr-Nd-Pb-Hf isotope results from ODP Leg 187: Evidence for mantle dynamics of the Australian-Antarctic Discordance and origin of the Indian MORB source [PDF]

, 2002
New high precision PIMMS Hf and Pb isotope data for 14–28 Ma basalts recovered during ODP Leg 187 are compared with zero-age dredge samples from the Australian-Antarctic Discordance (AAD).

Multi‐Year Monitoring of Small, Threatened Macropods in Two Subtropical Australian Forests Reveals Varied Stability Between Northern Long‐Nosed Potoroo (Potorous tridactylus tridactylus) Populations

Ecological Management &Restoration, Volume 27, Issue 2, May 2026.
ABSTRACT Multi‐year population studies are central to conservation efforts to help determine the status of populations and the necessity of interventions. Small, threatened macropod marsupials are highly susceptible to decline and extinction, yet few studies report multi‐year dynamics of their populations.

Evaluating Bayesian Morphological Clocks for Estimating a Dated Phylogeny in a Relict and Fossil‐Rich Family of Wasps (Hymenoptera, Chrysidoidea)

Zoologica Scripta, Volume 55, Issue 3, Page 448-463, May 2026.
ABSTRACT In recent years, a wide array of tools originally developed for molecular dating analyses has been adapted for use within a morphological clock perspective. This is of paramount relevance for taxonomic groups that cannot be sampled in forms suitable for DNA extraction.

Seismic anisotropy and mantle dynamics beneath Maitri Station in central Dronning Maud Land, East Antarctica: new insights from shear wave splitting analysis of core-refracted and direct S-phases

Polar Research
To elucidate the Gondwana supercontinent, we investigate mantle dynamics in Dronning Maud Land, Antarctica, using shear wave splitting analysis. This involves 12 S-phase teleseismic events and 38 core refracted phase (SKS, SKKS, PKKS and PKS) events ...

Exploring plane symmetric space-time in f(R) modified gravitational theory

East European Journal of Physics
This paper investigates a plane-symmetric cosmological model (PSCM) in the context of modified f(R) gravity theory, incorporating both vacuum and non-vacuum scenarios. A perfect fluid is assumed as the matter source.
