Herbicide impacts on exotic grasses and a population of the critically endangered herb "Calystegia affinis" (Convolvulaceae) on Lord Howe Island [PDF]

open access: yes, 2013
Introduced perennial grasses are capable of altering the habitat of native species, causing reductions in population size and vigour, and potentially affecting life-history processes such as survival, pollination and seedling recruitment. We examined the

Pilliga Ghosts: The Novel Fungi of the Rivers, Creeks, Lakes, and Dams of the Narrabri Region, Australia

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Freshwater systems of the semi‐arid Narrabri region, Australia, are hotspots of novel fungal and eukaryote diversity, dominated by zoosporic fungi and unclassified lineages. ITS‑based DNA and water chemistry analyses across various water bodies revealed strong seasonal patterns, a scarcity of aquatic hyphomycetes that may reflect environmental ...

Early recognition by Ball and Hooker in 1878 of plant back-colonization (boomerang) events from Macaronesia to Africa [PDF]

open access: yes, 2020
Recent work in island biogeography has shown that back-colonization (‘boomerang’ events) from islands to continents have occurred more frequently than previously understoodWe report possibly the earliest inference of this pattern, by John Ball and Joseph

Alternative Approaches and Plant‐Based Remedies for Livestock Health Management Among the Batswana of Southern Africa: A Review

open access: yesChemistry &Biodiversity, Volume 23, Issue 4, April 2026.
ABSTRACT Due to limited access to, and the high cost of conventional veterinary services, Batswana communities often rely on ethnoveterinary practices for livestock health management. This review provides an in‐depth analysis on the ethnoveterinary uses, biological properties and safety assessment of plants utilised in livestock husbandry. A systematic

Tree Seedling‐Recruitment in Temperate and Subtropical Species: A Systematic Narrative Review of Biotic and Abiotic Modifiers, and Experimental Treatments

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Our systematic review of 91 peer‐reviewed articles on tree recruitment highlights a research bias toward seedling‐focused studies and reveals a high prevalence of nonsignificant results. We recommend targeted experimental work on seedling treatments, mycorrhizal associations, fertilization, warm stratification, scarification, and chemical treatments ...
