Littoral habitat structure influences freshwater crayfish populations in five volcanic lakes of Aotearoa New ZealandNARA Subscribed
Freshwater crayfish are increasingly threatened by habitat degradation, declining water quality, and invasive species. In Aotearoa New Zealand, lake populations of the endemic northern freshwater crayfish Paranephrops planifrons (kōura) have declined by up to 91%. Identifying key habitat requirements is essential to improve the conservation of crayfish facing multiple threats. To assess littoral habitat associations, we survey...
Towards Holistic, Justice‐Oriented, and Coordinated Freshwater Fish Science and Governance in Aotearoa New ZealandNARA Subscribed
Aotearoa New Zealand faces accelerating loss of freshwater fish biodiversity and growing pressures on culturally significant fisheries. Technical solutions alone have failed because the challenge is not only ecological, but also institutional, cultural, and relational. Change is needed across policy, research, and practice to drive better outcomes for freshwater fish, beginning with how science is conceived and undertaken. Dra...
Sea to the mountains: quantifying freshwater eel and trout diet reliance on marine subsidies from upstream migrating fishNARA Subscribed
Despite the Southern Hemisphere's high proportion of endemic diadromous fish, the trophic role of upstream migrating forage fish in freshwater ecosystems remains unquantified. We combined food web δ 13 C and δ 15 N analyses with fish biomass estimates to quantify estuarine resource contribution (from the ecologically significant Waituna lagoon) to the diet and growth of the apex predators, longfin eels ( Anguilla dieffenbachii...
Induction of metallothionein in the common bully ( Gobiomorphus cotidianus ) from the Motueka RiverNARA Subscribed
The Motueka catchment is a major river system in the South Island, New Zealand, typically considered to be of ‘good water quality’. The catchment has high metal inputs originating from a mineral belt in the headwaters. This study investigated the induction of metallothionein (MT) in the common bully, Gobiomorphus cotidianus , to assess exposure to trace metal contamination in the Motueka River. The results showed a significant...
Purpose To determine the relationship between metabolic fitness test scores and performance in police occupational tasks. Methods Retrospective data from 106 law enforcement officers who completed two metabolic fitness assessments [anaerobic: a 20-m (10-m and 20-m splits) sprint, aerobic: 20 m Multi-Stage Fitness Test (20 m-MSFT)] and three routine occupational tasks [1.22 m Fence jump (FJ), 8.5 m Victim Drag (VD with 102.3 kg...
Motivation The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community‐led open‐source database of biodiversity time series. Our goal is to accelerate and facilitate quantitative analysis of temporal...
