Complex sociality in primates often is argued to have evolved after the appearance of diurnal activity. Studying the behaviour of nocturnal primates is fundamental to understanding the evolutionary origins of primate behaviour and ecology, yet much less is known about the nature of sociality in nocturnal primate species than their diurnal counterparts. We investigated group size, communication, and social interactions in free-...
High‐frequency sampling captures variability in phytoplankton population‐specific periodicity, growth, and productivityNARA Subscribed
The Hawaii Ocean Time‐series (HOT) at Station ALOHA (22.75°N, 158°W) in the North Pacific Subtropical Gyre (NPSG) serves as a critical vantage point for observing plankton biomass production and its ecological implications. However, the HOT program's near‐monthly sampling frequency does not capture shorter time scale variability in phytoplankton populations. To address this gap, we deployed the SeaFlow flow cytometer for conti...
Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disab...
Salmonid diseases caused by infections of Flavobacterium psychrophilum , the causative agent of bacterial coldwater disease, remain difficult to manage as novel, pathogenic strains continue to emerge in aquaculture settings globally. To date, much of the research regarding treatment options and vaccine development has focused on rainbow trout ( Oncorhynchus mykiss ), but other inland‐reared salmonids are also impacted by this...
Isolation and experimental challenge of cultured burbot ( Lota lota maculosa ) with Flavobacterium columnare and Aeromonas sp. isolatesNARA Subscribed
Burbot ( Lota lota maculosa ) are a potential new species for commercial aquaculture. As burbot culture expands, there is a need to further define pathogen susceptibility and characterize aspects of the burbot immune response in an effort to assess fish health. A recent clinical diagnostic case from juvenile burbot reared at a commercial production facility resulted in the isolation and identification of Flavobacterium columna...
Murihiku Cultural Water Classification System: enduring partnerships between people, disciplines and knowledge systemsNARA Subscribed
The Murihiku Cultural Water Classification System is founded on partnerships between people, disciplines and knowledge systems. This freshwater management framework is being developed at the scale of the Te Ara Koroka Pounamu Trail. Numerous barriers prevented Ngāi Tahu ki Murihiku use of the trail from around the 1880s; however, this cultural landscape and the values, beliefs and practices it supports (past, present and futur...
Validation of diagnostic assays to screen broodstock for Flavobacterium psychrophilum infectionsNARA Subscribed
It is hypothesized that the frequency of bacterial coldwater disease outbreaks can be reduced through the detection of the aetiologic agent, Flavobacterium psychrophilum , in broodstock followed by culling of eggs from heavily infected broodstock. Before a culling programme can be instituted, however, it is necessary to determine the sensitivity and specificity of existing assays for the detection of F. psychrophilum . In this...
In this study, susceptibility and potential carrier status of burbot, Lota lota , were assessed for five important fish pathogens. Burbot demonstrated susceptibility and elevated mortality following challenge with infectious haematopoietic necrosis virus (IHNV) by immersion and to Aeromonas salmonicida by intraperitoneal (i.p.) injection. IHNV persisted in fish for at least 28 days, whereas A. salmonicida was not re‐isolated b...
Flavobacterium psychrophilum is the aetiological agent of rainbow trout fry syndrome and bacterial cold water disease. This study examined the genetic diversity of F. psychrophilum isolates retrieved from multiple epizootics at rainbow trout, Oncorhynchus mykiss , rearing facilities and from spawning coho salmon, O. kisutch . A total of 139 isolates were confirmed as F. psychrophilum by PCR assay and were further typed using p...
