Invasive mammals disrupt sea–land nutrient inputs over 169 years on subtropical oceanic islands

open access: yesEcosphere, Volume 17, Issue 9, September 2026.
Abstract Invasive mammals have severely impacted oceanic islands, reducing or extirpating seabird populations and driving the collapse of nutrient flows with lasting ecosystem effects. We investigated these dynamics on contrasting subtropical oceanic islands in the South Pacific: Rangitāhua, a large island where goats, cats, and rats caused the ...

The thermal responses of barren‐forming urchins: Common patterns and knowledge gaps

open access: yesEcosphere, Volume 17, Issue 9, September 2026.
Abstract As climate change accelerates, there is increasing need to understand how species and ecosystems respond to warming. The challenge we face is the huge diversity of responses among species, and their variability across biological, temporal, and spatial scales.

Corallivore assemblage, feeding behavior, and cover of Acropora corals drive fish corallivory on tropical reefs

open access: yesEcosphere, Volume 17, Issue 9, September 2026.
Abstract Understanding spatial patterns and drivers of corallivory is essential for assessing reef resilience and identifying recovery pathways. Fish corallivory patterns arise from the complex direct and indirect effects of key factors, including food availability (cover of preferred corals), the nature of the corallivore assemblage (richness and ...

Reducing consumer pressure increases community dissimilarity leading to coral‐ or algal‐dominance on a coral reef

open access: yesEcology, Volume 107, Issue 9, September 2026.
Abstract In many ecosystems, anthropogenic influences are altering the strength of top‐down (e.g., herbivory and predation by consumers) and bottom‐up (e.g., nutrients) processes through the exploitation of consumers and increasing anthropogenic nutrient inputs.

Fish Community Composition Revealed by eDNA Metabarcoding in Mangrove‐Associated Lagoons of Negombo and Puttalam, Sri Lanka

open access: yesEnvironmental DNA, Volume 8, Issue 5, September‐October 2026.
eDNA metabarcoding revealed distinct fish community composition between Negombo and Puttalam lagoons, with richness broadly comparable to conventional surveys. The approach detected diverse taxa, including cryptic taxa, demonstrating its value as a complementary tool for biodiversity monitoring in Sri Lanka's mangrove‐associated lagoons.

Altered Coral‐Turf Algae Competition Leads to the Passive Dissolution of Coral Skeletons Under Ocean Acidification

open access: yesGlobal Change Biology Communications, Volume 1, Issue 3, September 2026.
Under ocean acidification, turf algae are favored over corals, shifting the competition outcome and decreasing coral survival. The local pH microenvironment under the turf, resulting from associated biological activity, drives the dissolution of the coral carbonate skeleton.

Age‐ and Growth‐Based Life‐History Traits of Striated Surgeonfish (Ctenochaetus striatus) and Achilles Tang (Acanthurus achilles) from Miti‘āro, Cook Islands

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 3, September 2026.
Striated surgeonfish (Ctenochaetus striatus) and Achilles tang (Acanthurus achilles) are two surgeonfish species commonly harvested for subsistence on Miti‘āro, Cook Islands. Using individuals collected by local fishers, this study provides the first age‐ and growth‐based assessment of these species from Miti‘āro.

Fast‐Growing, Short‐Lived, and Sex‐Changing: Life History of the Blue‐Barred Parrotfish (Scarus ghobban) From the Solomon Islands

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 3, September 2026.
The population dynamics of the blue‐barred parrotfish (Scarus ghobban) was examined to estimate key life‐history traits of this important reef fishery species in the Solomon Islands. The population was dominated by individuals within the 220–239 mm size class, corresponding to a modal age of 1‐year‐olds.
