Molluscan foraging efficiency and patterns of mobility amongst foraging agriculturalists: a case study from northern New Zealand

A New Zealand example illustrates the potential of foraging efficiency (FE) measures to inform not only on human-prey dynamics, but also to help identify situations where mobility is constrained or stimulated. Marked declines in Māori molluscan FE, coupled with increased shellfish usage, are identified over a ca. 450-year period at the coastal locality of Harataonga Beach, New Zealand. The potential effects of climate change are considered using newly available southwest Pacific multi-proxy records and temperature sensitive species, but correlations are lacking. The molluscan results signal possible restrictions on logistic and/or residential mobility in late prehistory, while evidence from the broader cultural landscape points to increasing agricultural investments and marked social competition. The Ideal Free Distribution model (IFD) is used to consider regional-scale interactions between foraging efficiency, agricultural developments, and competition, and their effects on mobility. Geographic and temporal variation in the patterning and causes of population movements is highlighted through this model, particularly differences between large game foragers in the south and populations with mixed economies in the north. In late prehistory, many northern areas including Harataonga apparently experienced reductions in the geographic scale of population movements, coupled with intensified intra-territorial mobility. The latter was an outcome of labour being widely dispatched across tribal territories, quasi-specialisation in subsistence tasks, and pooling and exchange of resources through a variety of social mechanisms which often involved population movements.     

Pinniped behavior, foraging theory, and the depression of metapopulations and nondepression of a local population on the southern Northwest Coast of North America

Models derived from foraging theory suggest that high-value prey will be depressed (encounter rates will decrease) relative to low-value prey as human predation intensifies. Numerous case studies in ethnographic and zooarchaeological settings indicate depression of prey is very common. Exceptions to depression are few and have been cited as evidence of conservation and resource management. Reanalysis of pinniped and ungulate data from sites on the Oregon coast indicates that the metapopulation (entire population in the region) of otariids was depressed but a single local population of Steller sea lions exploited over a span of 600 years reached an equilibrium with human predation and was not subsequently depressed. This local population was not historically documented, and thus must have been extirpated by commercial sealing in the late nineteenth century. This singular case of prehistoric epiphenomenal conservation was an unintentional result of human predation that took advantage of the lack of escape behaviors among breeding male Steller sea lions.     

The growth of antinuclearism in New Zealand

This paper explores the transformation of antinuclear opinion in New Zealand into a more durable and structured political orientation. Antinuclear opinion first gripped a large portion of the New Zealand public after that nation's government banned the entry of United States nuclear warships in 1984. At that time, the public rallied behind the government's action. This consolidation effect, however, showed signs of being impermanent by 1986; antinuclear opinion appeared to be on the wane. Surprisingly, by 1989 this sentiment had finned into a more structured attitude, regardless of the fact that the government responsible for the nuclear ships ban had become very unpopular. The youthful cast to antinuclearism in New Zealand suggests that this orientation is in the process of becoming a fixture of that country's political culture. Political socialisation experiences best explain the continuation and growth of this orientation. The database used in this study comes from a series of national surveys—the most pertinent of which are polls conducted in 1985 and 1989.     

The impacts of extra-territorial voting: Swings,interregnums and feedback effects in New Zealand elections from 1914 to 2011

How are elections affected by the votes of people living abroad? The majority of states now allow extra-territorial voting in some form, but the research literature on this topic remains underdeveloped. Moreover, even though extra-territorial voting raises issues about the relationship between territory and political obligation that are relevant to political geographers, political geography has been under-represented in discussions on the topic. Against this background, this research examines a century of overseas voting impacts in New Zealand, a country with an unusually long recorded history of such activity. The study identifies three types of extra-territorial voting impact over the period 1914-2011, referred to as swings, interregnums and feedback effects.     

Condition reporting and monitoring of archaeological sites: The use of large-scale vertical aerial photographs in New Zealand

Abstract

Large-scale aerial photographs (approximately 1:2000 to 1:10000 scale on the negative) have a number of virtues for condition reporting. The same site can be photographed at intervals so that rate of change can be measured. The record is objective and it gives sufficient detail to observe not only patterns but also the details of condition in such matters as past repairs, sheep tracking or the existence and state of repair of fences. In addition, photographic prints provide a ready basis for annotation. They are the primary record of condition and may highlight and focus the needs for conservation intervention. Archiving of photographs makes possible future study in the light of new research interests. Monitoring using photographs taken at regular intervals is also recommended.     

The age of the Takatika Grit,Chatham Islands,New Zealand

Hollis, C.J, Stickley, C.E., Bijl, P.K., Schiøler, P., Clowes, C.D., Li, X, Campbell, H. March 2017. The age of the Takatika Grit, Chatham Islands, New Zealand. Alcheringa 41, xxx–xxx. ISSN 0311-5518.

The oldest Paleogene strata on Chatham Islands, east of New Zealand, are the phosphatized conglomerates and sandstones of the Takatika Grit that crops out on the northeastern coast at Tioriori and unconformably overlies the Chatham Schist. An intact Cretaceous–Paleogene boundary transition is not preserved at this locality. New biostratigraphic analysis of dinoflagellate, diatom and radiolarian microfossil assemblages confirms that the Takatika Grit is of late early–middle Paleocene (New Zealand Teurian stage) age but contains reworked microfossils of early Campanian (Early Haumurian) age. Vertebrate fossils found in this unit are inferred to be a mixture of reworked Cretaceous and in situ Paleocene bones and teeth. The overlying Tutuiri Greensand is of middle–late Paleocene age in its lower part and also contains reworked Cretaceous microfossils.

Schooling on the Missionary Frontier: The Hohi Mission Station,New Zealand

Schooling was integral to the process of missionization in many of the places where it occurred throughout the world, yet it has scarcely been explored through the archaeological record. Excavations at Hohi, New Zealand, located a school founded by CMS missionaries in 1816, providing a material record that, in conjunction with documentary sources, enables reconstruction of schooling during the earliest stages of cultural engagement in this part of the Pacific. The motivations of both missionaries and indigenous Maori in the establishment and erratic progress of this school are examined, highlighting the role of indigenous agency in the cultural engagements that played out there.     

Social groups,sport and political engagement in New Zealand

Many prominent social theorists contend that memberships in voluntary associations make major contributions to making citizens more engaged with democracy. Although substantial attention has been directed at the potential role of sports groups, previous studies using survey data have not found membership in sports groups to be associated with political activity. New Zealand presents an important context for testing this theory, given its high levels of public participation in sports groups. We find that membership in sports and other social groups is associated with higher levels of political engagement. We discuss how these findings advance our understanding of the role that specific group memberships may have in democratic societies.
