Age Estimates

New 14C ages date the eruptions that produced the White River and Bridge River tephras, two important Holocene marker beds in western Canada. The 14C ages were obtained on trees in growth position buried in coarse tephra and a pyroclastic flow near the source vents. The mean calendric age of the White River eruption, based on four 14C ages, is 1147 cal years BP (calibrated years, approximately equivalent to calendric years) or AD 803 (the 2σ age range, obtained from the two most precise 14C ages, is 1014–1256 cal years BP or AD 694–936). The mean age of the Bridge River eruption, determined both from (i) the single most precise outer-ring 14C age and (ii) the weighted mean of six outer-ring 14C ages is 2360 cal years BP or 411 BC (2σ age range = 2349–2704 cal years BP or 755–400 BC).

Species Groups

AbstractThe New World species of Trissolcus, exclusive of the flavipes and thyantae species groups, are revised. This encompasses seven species: T. basalis (Wollaston) recorded in the southeastern USA, West Indies, Venezuela, and southeastern Brazil; T. cosmopeplae (Gahan) from the USA and Canada; T. erugatus n. sp. from the western USA and Canada; T. hullensis (Harrington) widely distributed throughout Canada, USA, Mexico, Dominica, and Venezuela; T. radix n. sp. from Guatemala, Costa Rica, Colombia, Venezuela, and the southeastern USA; T. solocis n. sp. from Mexico and the southeastern USA; and T. utahensis (Ashmead) from the western USA and Canada. Available host information for each species is summarized. These species are described and an identification key is provided.

Throw Trap

It is unclear how urbanization affects secondary biological production in estuaries in the southeastern USA. We estimated production of larval/juvenile Fundulus heteroclitus in salt marsh areas of North Carolina tidal creeks and tested for factors influencing production. F. heteroclitus were collected with a throw trap in salt marshes of 5 creeks subjected to a range of urbanization intensities. Multiple factor analysis (MFA) was used to reduce dimensionality of habitat and urbanization effects in the creeks and their watersheds. Production was then related to the first 2 dimensions of the MFA, month, and year. Lastly, we determined the relationship between creek-wide larval/juvenile production and abundance from spring and abundance of adults from autumn of the same year. Production in marsh (g m-2 d-1) varied between years and was negatively related to the MFA dimension that indexed salt marsh; higher rates of production were related to creeks with higher percentages of marsh. An asymptotic relationship was found between abundance of adults and creek-wide production of larvae/juveniles and an even stronger density-dependent relationship was found between abundance of adults and creek-wide larval/juvenile abundance. Results demonstrate (1) the ability of F. heteroclitus to maintain production within salt marsh in creeks with a lesser percentage of marsh as long as this habitat is not removed altogether and (2) a density-dependent link between age-0 production/abundance and subsequent adult recruitment. Given the relationship between production and marsh area, natural resource agencies should consider impacts of development on production when permitting construction in the southeastern USA.

Diaspora Policy

AbstractPolicy towards Hungarians living in neighbouring countries has been a central issue for Hungarian governments, yet Hungarian diaspora living mainly in Western Europe and North America have received very little attention. This has changed after the 2010 landslide victory of Fidesz. The new government introduced a structured policy focused on engaging Hungarian diaspora, largely due to the nationalist rhetoric of the governing party. The article argues that this change reflects a turn of Hungarian nationalism into what Ragazzi and Balalowska (2011) have called post-territorial nationalism, where national belonging becomes disconnected from territory. It is because of this new conception of Hungarian nationalism that we witness the Hungarian government approach Hungarian communities living in other countries in new ways while using new policy tools: the offer of extraterritorial citizenship; political campaigns to motivate the diaspora to take part in Hungarian domestic politics by voting in legislative elections; or the never-before-seen high state budget allocated to support these communities. Our analysis is based on qualitative data gathered in 2016 from focus group discussions conducted in the Hungarian community of Western Canada to understand the effects of this diaspora politics from a bottom-up perspective. Using the theoretical framework of extraterritorial citizenship, external voting rights and diaspora engagement programmes, the paper gives a brief overview of the development of the Hungarian diaspora policy. We focus on how post-territorial nationalism of the Hungarian government after 2010 effects the ties of Hungarian communities in Canada with Hungary, how the members of these communities conceptualise the meaning of their “new” Hungarian citizenship, voting rights and other diaspora programmes. We argue that external citizenship and voting rights play a crucial role in the Orbán government’s attempt to govern Hungarian diaspora communities through diaspora policy.
