Multi‐year partner fidelity is associated with higher annual reproductive output in a biparental subtropical shorebird

Oikos, Volume 2026, Issue 8, August 2026.
Partner fidelity is a key component of reproductive strategies in socially monogamous species, yet its adaptive value remains context dependent and poorly understood outside environments with short breeding seasons. In most bird species, partners may remain together or re‐pair between successive nesting attempts, but it remains unclear which components

HOW TO ESTIMATE BLACK WATTLE ABOVEGROUND BIOMASS FROM HETEROSCEDASTIC DATA?

FLORESTA, 2020
This study developed a system of equations for predicting total aboveground and component biomass in black wattle trees. A total of 140 black wattle trees at age 10 years were measured regarding their diameter at 1.30 m height above the ground (d), total tree height (h), basic wood density (branches and stem), and biomass (stem, crown, and aboveground).

Temognatha sundholmi Lang sp. nov. (Coleoptera: Buprestidae), a New Species From the Great Victoria Desert and New Host Plants: An Investigation Using DNA Barcoding With Implications for Taxonomy of Temognatha and Melobasis

Austral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT A new species of jewel beetle, Temognatha sundholmi Lang, sp. nov., is described from the Great Victoria Desert in South Australia. A broader investigation, using mtDNA COI ‘barcode’ sequences from 178 specimens representing 54 buprestid species, places the new species with Temognatha flavocincta (Gory & Laporte, 1838) in the informal ...

Population Collapse of the Spidery Wattle (Acacia araneosa) During Late Holocene Aridification: Genomic Evidence for Critically Endangered Status

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Acacia araneosa is an extremely range‐restricted aridland shrub endemic to South Australia, coexisting sympatrically with the more common Acacia rivalis. Using SNP data we explore the species boundaries between the two and find evidence of non‐threatening hybridisation. We find strong and short‐range barriers to gene flow between the two A.

The origins of tannins and flavonoids in black-wattle barks and heartwoods, and their associated ‘non-tannin’ components [PDF]

Biochemical Journal, 1965
1. The distributions of flavonoid, carbohydrate, amino acid and imino acid components in the leaves, twig bark, stem bark, root bark and heartwoods of the black-wattle tree were compared by paper chromatography after their isolation from specific portions of the tree. 2.
