Nuclear DNA content in Galaxias maculatus (Teleostei: Osmeriformes: Galaxildae)

open access: yes, 2021
The nuclear DNA content (2C value) was determined in the commercial fish Galaxias maculatus (Galaxiidae) was determined by microdensitometry of erythrocyte nuclei after Feulgen staining; rainbow trout erythrocytes with a known 2C value were used as a ...

Culvert baffle design to improve fish passage for small‐bodied fishes: A rapid evidence synthesis

open access: yesConservation Science and Practice, Volume 7, Issue 7, July 2025.
The overall weight of evidence indicates that the addition of baffles generally increases the passage of small‐bodied fishes through culverts. However, there is an emerging consensus that baffles that minimize the generation of large recirculation zones while maximizing the area of low velocities are most suitable for enhancing passage.

Luz difusa en cúmulos y grupos de galaxias [PDF]

open access: yes, 2009
La luz difusa está compuesta por estrellas desligadas de las galaxias del cúmulo y que se mueven bajo la acción del potencial global del cúmulo. Esta componente cúmular corresponde a un 5-15% de la masa total del cúmulo.

Common bully (Gobiomorphus cotidianus) and mosquitofish (Gambusia affinis) shift littoral zooplankton community composition to smaller bodied taxa

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 2, Page 339-355, June 2025.
ABSTRACT We investigated the effects of native common bully (Gobiomorphus cotidianus) and non‐native western mosquitofish (Gambusia affinis) on zooplankton assemblages in an outdoor mesocosm experiment. Twenty‐one 100 L mesocosms containing zooplankton were assigned either four G. cotidianus, four G. affinis, or were left as a control group (i.e.

Accounting for interspecies and intraspecies variation in swimming performance for fish passage solutions

open access: yesJournal of Applied Ecology, Volume 62, Issue 2, Page 231-241, February 2025.
Previous maximum traversable water speeds for fish passage designs have been based on average swimming ability, but this approach only enables fish that are better than the average swimmers of their species to overcome barriers. This study highlights the importance of evidence‐based designs for successful fish passage solutions to account for the ...

Fishways provide catchment-scale improvements to common galaxias (Galaxias maculatus) upstream of a barrier in south-eastern Australia

open access: yes, 2023
The common occurrence of dams is a major threat to riverine fish communities globally and a common remediation technique for fragmented fish communities is fishway construction.
