Extreme glacial legacies: a synthesis of the Antarctic springtail phylogeographic record
No full textWe review current phylogeographic knowledge from across the Antarctic terrestrial landscape with a focus on springtail taxa. We describe consistent patterns of high genetic diversity and structure among populations which have persisted in glacial refugia across Antarctica over both short (10 Mya) timescales. Despite a general concordance of results among species, we explain why location is important in determining population genetic patterns within bioregions. We complete our review by drawing attention to the main limitations in the field of Antarctic phylogeography, namely that the scope of geographic focus is often lacking within studies, and that large gaps remain in our phylogeographic knowledge for most terrestrial groups.Angela McGaughran, Mark I.

Identifying appropriate sampling and modelling approaches for analysing distributional patterns of Antarctic terrestrial arthropods along the Victoria Land latitudinal gradient
No full textBiotic communities in Antarctic terrestrial ecosystems are relatively simple and often lack higher trophic levels (e. g. predators); thus, it is often assumed that species' distributions are mainly affected by abiotic factors such as climatic conditions, which change with increasing latitude, altitude and/or distance from the coast. However, it is becoming increasingly apparent that factors other than geographical gradients affect the distribution of organisms with low dispersal capability such as the terrestrial arthropods. In Victoria Land (East Antarctica) the distribution of springtail (Collembola) and mite (Acari) species vary at scales that range from a few square centimetres to regional and continental. Different species show different scales of variation that relate to factors such as local geological and glaciological history, and biotic interactions, but only weakly with latitudinal/altitudinal gradients. Here, we review the relevant literature and outline more appropriate sampling designs as well as suitable modelling techniques (e. g. linear mixed models and eigenvector mapping), that will more adequately address and identify the range of factors responsible for the distribution of terrestrial arthropods in Antarctica.</p
Russian Reception by James Hogg (Soviet period)
No full textThe article continues a series of works devoted to the Russian reception of the Scottish writer James Hogg (1770–1835), a famous interpreter of folk ballads and author of The Private Memoirs and Confessions of a Justified Sinner (1824). Facts and materials related to the perception of J. Hogg in Russia in Soviet times are collected and summarized. It is indicated that during the period under review, in the studies of Russian literary scholars, separate judgments were made on the traditions of R. Burns in the works of J. Hogg, the role of W. Scott in his fate, etc. The Russian translations of the works of the English and American classics (in particular, J. G. Byron, E. A. Poe, J. F. Cooper) that appeared in the Soviet era, which contained references to the Scottish poet, are noted. The publications, which included information about J. Hogg, are comprehended, with special attention paid to S. Ya. Marshak’s epigram “Inscription on the Stone” mentioning J. Hogg’s name, the research of M. P. Alekseev, B. G. Reizov, R. M. Samarin and etc. The scientific works of A. D. Ivanova, first of all her Ph.D. thesis “The originality of the artistic work of James Hogg” (1990), which contributed, along with the changes in social life that occurred at the turn of the J. Hogg, the emergence of new translations of his works are analyzed

Marine wood borers in New Zealand: an interdisciplinary study of their origins, impacts and management
No full textNon-indigenous marine species are a major concern worldwide. For some species, insufficient historical and biogeographical data can leave their origin and patterns of dispersal difficult to determine. Among such species are marine wood borers. This thesis uses an interdisciplinary approach, combining both historical and biological methods, to address marine borer impacts, management attempts, and their status in New Zealand.
This research had two key components. Firstly, a historical review sought to improve the understanding and awareness of the historic impacts and responses to borers, with particular reference to New Zealand between 1850 and 1930. Marine wood borers have had profound impacts throughout history, responsible for significant structural and economic damage to wooden ships and marine infrastructure globally. In New Zealand, trade and economy played an important role in providing both the transportation vectors and infrastructure for marine wood borers to inhabit. Ongoing trialling of timber alternatives and chemicals for the preservation of infrastructure followed, with little success until the introduction of ferro-concrete in the early 1900s. When considered in a global context, the New Zealand case study of borer impacts and management attempts highlights their significant role in environmental history.
Mitochondrial DNA (COI) sequence analyses were used to examine the questionable invasion histories and status of common marine wood borers in New Zealand. It has been assumed that many marine wood borers invaded New Zealand via wooden ships. However, these purported introductions are historic, and the specific origins of many species are unclear. Species from three families and two phyla were collected around the North Island, New Zealand; Teredinidae (Bivalvia: Mollusca), Sphaeromatidae and Limnoriidae (Isopoda: Arthropoda). Low levels of genetic divergence (0-2%) were found among the New Zealand populations of two species, Limnoria quadripunctata and Sphaeroma quoianum, suggesting a non-indigenous status. Limnoria quadripunctata also showed a close genetic affinity to populations in Chile, supporting a non-indigenous status, with its widespread distribution in New Zealand explained by multiple introductions. For Lyrodus pedicellatus, a lack of genetic affinity to conspecifics sequenced elsewhere (France), greater genetic diversity compared to the native Bankia australis, and evidence of population structuring among New Zealand locations, suggested L. pedicellatus may be native to New Zealand. Lyrodus pedicellatus from New Zealand was highly divergent (>20%) from global L. pedicellatus populations, suggesting that either identifications of specimens on global databases are incorrect, or the New Zealand species represents a morphologically undescribed cryptic congener. In conclusion, COI sequences provided a useful tool in elucidating the status of marine wood borers in New Zealand, and highlighted a need for taxonomic resolution of some species.
Collectively the two chapters illustrate the knowledge gaps and lack of recognition surrounding marine wood borers, globally and in New Zealand. This research provides an extensive understanding of their significant historical role in marine environmental history and assists in re-evaluation of their current native or non-indigenous status in New Zealand
