Optimizing eDNA Replication for Standardized Application in Lotic Systems in Aotearoa, New Zealand
Environmental DNA, Volume 6, Issue 5, September–October 2024.The objective of this study was to optimize eDNA sample replication for the consistent characterization of freshwater fish and aquatic macroinvertebrate communities in flowing New Zealand waters, and ultimately, to inform the development of robust national monitoring standards. Results indicated that six replicates were needed to consistently detect 89.

Preliminary investigation of systematics of some Tasmanian Galaxiidae
Papers and proceedings of the Royal Society of Tasmania, 1966 The investigation has revealed no Tasmanian galaxiid identical with any New Zealand form. The fish known hitherto as Galaxias attenuatus in Tasmania is shown to be at least subspecifically different from the form bearing this name in New Zealand. The two forms are referred to the species maculatus Jenyns on the grounds of page precedence, and are ...

Gorges partition diversity within New Zealand flathead Galaxias populations
Journal of Fish Biology, Volume 104, Issue 4, Page 950-956, April 2024.Abstract Understanding the landscape factors governing population connectivity in riverine ecosystems represents an ongoing challenge for freshwater biologists. We used DNA sequence analysis to test the hypothesis that major geomorphological features underpin freshwater‐limited fish diversity in a tectonically dynamic region of New Zealand ...

Native fish translocations mediated by anthropogenic drainage modifications in southern New Zealand
New Zealand Journal of Zoology, Volume 51, Issue 1, Page 1-13, March 2024.ABSTRACT Freshwater‐limited fish populations are often tightly constrained by river drainage boundaries. As a case in point, the distribution of lineages within New Zealand’s diverse Galaxias vulgaris complex is broadly structured by geographic barriers, reflecting tectonic processes.

Environmental DNA, Volume 6, Issue 1, January–February 2024.At the remote UNESCO Word Heritage Site Te Wāhipounamu, we show that eDNA analysis is a highly sensitive tool with strong potential for biodiversity surveys, which is still limited by the unavailability of local reference data. We hope that by demonstrating the extend of divergence between eDNA and more traditional tools in a real‐life case study of a ...

Freshwater fish as hosts for parasites in Australia: How much do we really know?
Ecology of Freshwater Fish, Volume 33, Issue 1, January 2024.Abstract Australia has a highly endemic freshwater fish fauna, but basic biological knowledge for most is lacking. This includes an understanding, and description, of their parasite fauna. Additionally, the impacts of introduced fish species, and their parasites which have transferred across to native species, are also mostly unknown.

Observations on the Tasmanian mudfish, Galaxias cleaveri (Pisces: Galaxiidae)
Papers and Proceedings of the Royal Society of Tasmania, 1991 Meristic and morphometric comparisons are made of the three known populations of the Tasmanian mudfish; mainland Tasmania, Flinders Island and Victoria. The results of observations on the ecology and behaviour are reported.
