Spawning, egg development and recruitment of diadromous galaxiids in Taranaki, New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Ecology at Massey University [PDF]

open access: yes, 2002
Spawning biology of Galaxias postvectis Clarke (shortjaw kokopu) was investigated in streams in northwest Taranaki, New Zealand. Most G. postvectis were found to spawn near their adult habitat on the river bank during spate flows between May 9 and 17 ...

The impact of isosmotic conditions on the metabolism and hypoxia tolerance of a reportedly oxyconforming teleost

open access: yesJournal of Fish Biology, EarlyView.
Abstract Fish must manage the competing demands of ion balance and gas exchange across the gills – a physiological tension known as the osmorespiratory compromise. In dynamic estuarine environments, the osmorespiratory compromise may be exacerbated by variable salinity and periods of hypoxia that demand high respiratory work.

Haemoglobin and size dependent constraints on swimbladder inflation in fish larvae [PDF]

open access: yes, 2006
In developmental studies of fish species (especially physostomians) it could be demonstrated, that the lack of haemoglobin during larval and juvenile stages is a relatively common phenomenon. Generally it is linked with body translucency.

Ecology of common bully (Gobiomorphus cotidianus) in the Tarawera and Rangitaiki rivers: isolation by inland distance or anthropogenic discharge? [PDF]

open access: yes, 2009
Previous research has identified distinct genetic, life-history and reproductive differences between populations of common bully (Gobiomorphus cotidianus) upstream and downstream of a pulp and paper mill outfall on the Tarawera River in the Bay of Plenty,

Geological processes shaping freshwater biodiversity: a synthesis of global evidence

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1568-1581, June 2026.
ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...

Além das galáxias brilhantes: a descoberta da matéria escura e o papel de Vera Rubin [PDF]

open access: yesRevista Brasileira de Ensino de Física
Desde a década de 1930 os cientistas enfrentavam dificuldades para calcular a massa de aglomerados de galáxias a partir da luminosidade, pois os efeitos gravitacionais observados não correspondiam à soma das massas visíveis.

Swimming Under the Radar: Trout‐Free Kōaro Populations in Aotearoa Lakes and Tarns Are Rare, Understudied, and Disappearing

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 2, June 2026.
Over the last 150 years, most large, easily accessible lakes and tarns in Aotearoa (New Zealand) have experienced trout introductions or incursions, leaving few salmonid‐free reference lakes. Using database information and field surveys, we characterized lake, pond/tarn, and wetland systems found throughout Aotearoa that support populations of kōaro ...

Estimating the abundance of banded kokopu (galaxias fasciatus gray) in small streams by nocturnal counts under spotlight illumination [PDF]

open access: yes, 2002
The abundance of banded kokopu (Galaxias fasciatus Gray) in small streams has usually been determined by the labour intensive and invasive method of electric fishing.
