Ontogeny of rake mark scarring on common dolphins ( Delphinus delphis ): insights to aggression and affiliation?

Abstract Aggressive and affiliative interactions shape resource allocation, social structure and reproduction in social species. In delphinids, rake marks (parallel scars from tooth raking) indicate social interactions. When examined alongside ontogeny, demographic traits and sca...

Metabarcoding reveals mixed Cryptosporidium and apicomplexan infections in New Zealand dairy cattle

Abstract Cryptosporidium species are significant enteric parasites of cattle with zoonotic potential. Molecular surveillance of bovine cryptosporidiosis typically relies on 18S rRNA PCR and Sanger sequencing, which may underestimate mixed infections and overlook broader apicomple...

Food Sovereignty, Whakapapa, and Place

ABSTRACT Food sovereignty is increasingly promoted as an alternative to dominant food systems. In Aotearoa it is inseparable from Māori relationships to whenua and from colonial dispossession. This paper presents a kaupapa Māori review of academic, policy, and grey literature, wi...

From Uncertainty to Risk: How Firms Respond in Circular Economy Transitions

ABSTRACT The transition to a circular economy exposes firms to multiple sources of uncertainty, yet existing research largely treats these challenges as barriers rather than drivers of firm behavior. This paper develops a conceptual understanding of how uncertainty is translated...

Selected Physical and Geotechnical Properties of Loess in Wairarapa Valley, New Zealand

Loess up to 10 m thick covers marine terraces, old river aggradation terraces, and gentle hill country slopes in Wairarapa, New Zealand. In the drier eastern and southern parts of Wairarapa, the loess is subject to dry summer and autumn and wet winter and spring in most years. Un...

Effects of iso-nutritive creep-feeding formulations on nutrient digestibility, growth performance, and economic returns of Madura beef calves under smallholder conditions

Context Feeding locally designed creep feeds to Madura calves presents a viable opportunity for adoption by smallholder farmers. Aim This study evaluated the effects of iso-nutritive creep-feeding formulations on feed intake, nutrient digestibility, growth performance, feed effic...

Sugar-rich foods exacerbate antibiotic-induced microbiome disruption

Diet shapes the composition of the gut microbiota1; however, the specific effects of distinct food groups on microbiome dynamics are unclear, particularly in circumstances of extreme perturbation. Here we evaluated the relationship between diet and intestinal microbiome dynamics...

Tumor microbial biodiversity and microsatellite instability in colorectal cancer

Background Growing evidence links the gut microbiome to colorectal cancer (CRC) progression, with certain bacterial species enriched in specific molecular tumor subtypes. DNA mismatch repair deficiency in CRC, evidenced by the presence of microsatellite instability (MSI), has bee...

Melt evolution and crystal cargo uptake at Mount Ruapehu: a magma plumbing system characterized by narrow dikes and sills

Abstract To assess the magma plumbing architecture of Mount Ruapehu, an active stratovolcano in the Taupō Volcanic Zone (New Zealand), we combine whole rock, groundmass and crystal geochemistry of lava samples from the south-west flank, focusing on the Mangawhero (50–15 ka) and W...

Towards explainable sports analytics: A physics-based trajectory simulation model for predicting yards after catch in American football

Yards after catch (YAC) is one of the most consequential outcomes in American football, yet existing predictive models operate as opaque black boxes that cannot be interrogated by coaches or analysts. This study presents a physics-based trajectory simulation model that addresses...

Underground Signals: The Ecological Power of Root Volatiles

Root volatiles mediate diverse belowground interactions among plants, microbes, and invertebrates, but biological and environmental conditions strongly influence their production, movement, perception, and ecological effects. This review synthesizes current knowledge through an i...

Use of cannabidiol products in Canada, United States, Australia, Aotearoa New Zealand, United Kingdom and Germany: products, sources and reasons for use

Background Cannabidiol (CBD) has attracted scientific, clinical, and public interest due to its perceived therapeutic benefits and favourable safety profile. However, a gap remains in understanding how different CBD-only regulatory frameworks shape consumers interaction with the...

Implementing and upscaling pregnancy and postpartum physical activity: a workgroup report from the international society of behavioral nutrition and physical activity — from individual-level barriers to multilevel implementation and scale-up

Abstract Background Physical activity during pregnancy and the postpartum period is important for maternal health, yet participation remains suboptimal, and the implementation and scale-up of physical activity initiatives across diverse cultural and health-system contexts remain...

Advancing equity in mathematics education: stories of success

Despite ongoing global efforts to reform mathematics education, students continue to experience inequity and marginalisation in relation to mathematics learning identities, opportunities, outcomes, and advancement.A key focus of this special issue was to avoid 'gap gazing', an ap...

Beyond unstructured use: scaffolded integration of generative AI in assessment for learning

This study examined how scaffolded integration of generative artificial intelligence (GenAI) within an assessment task influenced students’ experience, evaluative engagement, learning, confidence, and competence. A cross-sectional quantitative survey was completed by 164 first-ye...

Corporate intentions and behaviours when complying with mandatory assurance of climate reporting: a qualitative study of New Zealand reporting entities

Purpose This study aims to examine how reporting entities in New Zealand have responded to mandatory requirements for assurance of climate reporting and the behavioural intentions that drive such responses. Design/methodology/approach The authors interviewed professionals from 15...

Myalgic encephalomyelitis/chronic fatigue syndrome and overlapping post-acute infection syndromes: international expert consensus framework for diagnostic standardization

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) lacks validated objective diagnostic criteria, leading to delayed diagnosis and inconsistent management. We aimed to establish an international expert consensus framework integrating measurable, risk-stratified assessmen...

One-Dimensional First Return Maps for the Two-Dimensional Border-Collision Normal Form with a Zero Determinant

Abstract The two-dimensional border-collision normal form is a four-parameter family of continuous, piecewise-linear maps. When this form has a zero determinant, all of its nonlinear dynamics are captured a one-dimensional first return map. The first return map is discontinuous a...

Exploring the impact of robot-based services on hotel brand image among senior consumers

Robot has introduced new opportunities for enhancing hotel brand image, yet few studies on hotel robots have focused on senior consumers. Drawing on the Information Systems Success (ISS) model, this study examines the impact of information quality, system quality, and service qua...

White Resilience: The Self-Sustaining Architecture of Whiteness Through Mediocrity, Fragility, and Rage

This article introduces the concept of white resilience as a theoretical framework for understanding the self-perpetuating capacity of whiteness as a structural, cultural, and communicative formation. Drawing on and synthesizing critical scholarship on white mediocrity, white fra...
