Responses of Reef Fish Populations to Similar Environmental Changes Across Distant Oceanic Islands

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 4, April 2026.
ABSTRACT Oceanic islands are among the most remote and understudied regions of the planet, yet they harbour unique reef fish communities that are increasingly vulnerable to global environmental change. Because these islands are geographically isolated, their populations are often assumed to respond mainly to local environmental conditions.

Zooarchaeological Analysis of an Atoll Assemblage From Central Micronesia

open access: yesArchaeology in Oceania, Volume 61, Issue 1, Page 177-198, April 2026.
ABSTRACT There has been a dearth of archaeological research on atolls in the central‐eastern Caroline Islands of Micronesia. This has limited our understanding of pre‐contact subsistence and settlement strategies in these more marginal and remote environments, particularly in regards to zooarchaeological data.

Adipocytes cause leukemia cell resistance to daunorubicin via oxidative stress response. [PDF]

open access: yes, 2016
Adipocytes promote cancer progression and impair treatment, and have been shown to protect acute lymphoblastic leukemia (ALL) cells from chemotherapies. Here we investigate whether this protection is mediated by changes in oxidative stress.

Lower Abundance of Young‐of‐the‐Year Fish in Alpine Rivers Affected by Hydropeaking: An Austrian Field Study

open access: yesEcohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Rapid sub‐daily flow fluctuations caused by hydroelectric power generation (hydropeaking) pose a significant challenge to aquatic ecosystems in Alpine rivers, particularly for young‐of‐the‐year (YOY) fish. Hydropeaking reduces recruitment rates through reduced spawning success and habitat availability and persistence, as well as increased ...

Optimal Strouhal number for swimming animals [PDF]

open access: yes, 2011
To evaluate the swimming performances of aquatic animals, an important dimensionless quantity is the Strouhal number, St = fA/U, with f the tail-beat frequency, A the peak-to-peak tail amplitude, and U the swimming velocity.

Identifying knowledge gaps about context dependency in freshwater species invasions

open access: yesOikos, Volume 2026, Issue 4, April 2026.
The abiotic template of freshwater ecosystems is being altered by human activity on a global scale, often promoting the establishment of new invasive taxa and increasing the likelihood of facilitation between invaders. These positive interactions represent a substantive threat to freshwater ecosystems by promoting the establishment and persistence of ...
