title: Population genetic structures of two New Zealand corophiid amphipods and the presence of morphologically cryptic species: Implications for the conservation of diversity

authors: Schnabel, Kareen E.

subjects: aquatic ecology

abstract: We evaluated the population genetic structures (allozyme variation) of Chaetocorophium lucas i (Hurley 1954) Karaman 1979 and Paracoro‐phium excavatum (Thomson 1884) Stebbing 1899 (Amphipoda: Crustacea) from the North Island and South Island of New Zealand. Individuals of C. lucasi were found in both freshwater and estuarine habitats, whereas P. excavatum was restricted to estuarine sites. Allele frequencies showed significant inter‐ and intra‐specific differences among populations of both C. lucasi and P. excavatum. C. lucasi appears to be a single species, albeit with considerable genetic differentiation among populations (FSX = 0.51). However, P. excavatum revealed even greater levels of genetic differentiation among populations (FST = 0.81), and may consist of at least three genetically distinct species. Geographic distance, perhaps dictated by prevailing ocean currents and overland dispersal routes, best explained observed patterns of differentiation among populations of both species. From a conservation perspective, the presence of morphologically cryptic species suggests that current taxonomic inventories of aquatic amphipods may be grossly underestimated.

title: Make me special: Gender differences in consumers’ responses to loyalty programs

authors: Melnyk, Valentyna

subjects: Gender differences

abstract: Current literature on loyalty programs emphasizes the importance of psychological rewards and special treatment. However, it is not clear if male and female customers respond to these incentives in a similar way. We explore the differential effect for female versus male consumers of two psychological rewards that are provided through a loyalty program (a) high status (e. g., Gold membership), and (b) personalization, at different levels of visibility to other consumers. Across three experiments and a field study, we find a coherent pattern of gender differences in the way customers respond to different types of psychological rewards in the context of loyalty programs. The results show that men respond more positively than women to loyalty programs that emphasize status, but only when their higher status is highly visible to others. In contrast, women respond more positively than men to loyalty programs that emphasize personalization, but only for personalization in private settings. We discuss managerial implications for the design of loyalty programs

title: Grounding our collective Talanoa, Enabling open conversations

authors: Fa'avae, David Taufui Mkiato

abstract: As co-editors in this special issue of the Waikato Journal of Education (WJE), we share our talanoa thoughts and open conversations from the University of Waikato in Kirikiriroa (Hamilton), a place and space that has a special relationship with Waikato-Tainui and the Kīngitanga. We acknowledge our ties with Māori as tangata moana (people of the ocean), noting the past as well as the existing vā connections between the Kīngitanga and other Pacific peoples and leaders, including the House of Tupou, the royal family of Tonga. We are also mindful of our responsibility to honour Te Tiriti and to the honouring of tangata whenua and their mana whenua. At the same time, we embrace the ancestral connections between Māori and Pacific people through shared common heritages (Te Punga Somerville, 2012), of voyaging, wayfinding, knowledge and ako by which they settled Moananuiākea (the Hawaiian term for the Pacific Ocean) in one of “the greatest feats in human history” (Hawaii State Legislature, 2021, n.p.). We hope this volume honours those relationships and our shared whakapapa, whanaungatanga, and kaupapa.
