Land‐use changes impact root–fungal network connectivity in a global biodiversity hotspot

open access: yesJournal of Ecology, Volume 113, Issue 5, Page 1136-1149, May 2025.
Dimensioning the impacts of rainforest transformations below‐ground is constrained by our understanding of fungal functional guilds. Highly modified systems exhibited fewer connections, suggesting a dynamic restructuring of root–fungal relationships in response to land‐use changes.

Progress and problems in the assessment of flower morphology in higher-level systematics [PDF]

open access: yes, 2018
Floral features used for characterization of higher-level angiosperm taxa (families, orders, and above) are assessed following a comparison of earlier (precladistic/premolecular) and current classifications.

Review of larval food plant associations of the Agaristinae (Lepidoptera: Noctuidae) in Australia

open access: yesAustral Entomology, Volume 64, Issue 2, May 2025.
Abstract The Australian Agaristinae comprises a small group of predominantly diurnal moths with aposematic larvae and adults that are assumed to be unpalatable to most predators. A critical review of the larval food plants of this subfamily based on published records in the literature, together with unpublished records, is presented.

High Species Diversity in Fleshy-Fruited Tropical Understory Plants [PDF]

open access: yes, 2001
Key innovations may increase the number of taxa in a clade that possesses the proposed innovation in comparison to its sister group that lacks the trait through either increased speciation or reduced extinction rates.

Chromosome‐level genome assembly of Iodes seguinii and its metabonomic implications for rheumatoid arthritis treatment

open access: yesThe Plant Genome, Volume 18, Issue 1, March 2025.
Abstract Iodes seguinii is a woody vine known for its potential therapeutic applications in treating rheumatoid arthritis (RA) due to its rich bioactive components. Here, we achieved the first chromosome‐level assembly of the nuclear genome of I. seguinii using PacBio HiFi and chromatin conformation capture (Hi‐C) sequencing data.
