The species of Massalongia recorded and described from the Southern Hemisphere are revised and it is shown that only one is present; M. patagonica which is widespread, with populations in Australia and New Zealand that differ from the South American populations, but at present best regarded as part of the variation of that species. Records from this hemisphere of all other species placed in the genus are incorrect. The type species, M. carnosa, is restricted to the Northern Hemisphere. Two species, M. antarctica and M. novozelandica cannot be identified precisely due to lack of sufficient type material and with the types as the only collections known of these, but none belongs in Massalongia according to available data. Massalongia griseolobata (from Gough Isl.) is shown here to belong in the Pannariaceae and is part of the parmelielloid clade. M. intricata (from South Georgia) and M. olechiana (from South Shetland) have both recently been correctly transferred to the genus Steinera in the Arctomiaceae.

Co-operation on an international scale is not easy to arrange in the most prosperous times: in these days of financial stress the difficulties of ensuring sufficiently close collaboration to make the second Polar Year a complete success are very great. Since the July statement of the position, published in The Polar Record, ideas have become appreciably clearer as to what is really likely to be done by the various co-operating countries in the year's programme. It now seems that while the relative completeness of the network of stations in the northern hemisphere is assured, there will be little special activity in the southern hemisphere, except within the domains of each of the countries interested. France may have to abandon her Kerguelen and St Paul projects, and recent events in the Argentine, Brazil and Chile have reduced the expectation of co-operation from these countries in establishing special island stations or even extending their present work in the South Atlantic. New Zealand, however, may still find funds for meteorological observations on Macquarie Island, where the Mawson Expedition of 1912–13 had a station.

Last Glaciation

Abstract. The Pleistocene sequence of Wanganui (North Island of New Zealand) and the succession of glaciations in the South Island are shortly reviewed. The Last Glaciation and the Postglacial time in New Zealand were, as C14 determinations definitly show, contemporaneous with those of the Northern Hemisphere. If the Last Glaciation was contemporaneous on the two Hemispheres, then the older ones must also have been contemporaneous. This does not agree with the MILANKOVITCH-curve, which in the form, as it has been given by M., cannot have been the cause of the ice ages.

Abstract. We present 60 years of Δ14CO2 measurements from Wellington, New Zealand (41° S, 175° E). The record has been extended and fully revised. New measurements have been used to evaluate the existing record and to replace original measurements where warranted. This is the earliest atmospheric Δ14CO2 record and records the rise of the 14C "bomb spike", the subsequent decline in Δ14CO2 as bomb 14C moved throughout the carbon cycle and increasing fossil fuel CO2 emissions further decreased atmospheric Δ14CO2. The initially large seasonal cycle in the 1960s reduces in amplitude and eventually reverses in phase, resulting in a small seasonal cycle of about 2 ‰ in the 2000s. The seasonal cycle at Wellington is dominated by the seasonality of cross-tropopause transport, and differs slightly from that at Cape Grim, Australia, which is influenced by anthropogenic sources in winter. Δ14CO2 at Cape Grim and Wellington show very similar trends, with significant differences only during periods of known measurement uncertainty. In contrast, Northern Hemisphere clean air sites show a higher and earlier bomb 14C peak, consistent with a 1.4-year interhemispheric exchange time. From the 1970s until the early 2000s, the Northern and Southern Hemisphere Δ14CO2 were quite similar, apparently due to the balance of 14C-free fossil fuel CO2 emissions in the north and 14C-depleted ocean upwelling in the south. The Southern Hemisphere sites show a consistent and marked elevation above the Northern Hemisphere sites since the early 2000s, which is most likely due to reduced upwelling of 14C-depleted and carbon-rich deep waters in the Southern Ocean. This developing Δ14CO2 interhemispheric gradient is consistent with recent studies that indicate a reinvigorated Southern Ocean carbon sink since the mid-2000s, and suggests that upwelling of deep waters plays an important role in this change.

AbstractThe bryozoan fauna from the South American Cenozoic is poorly known. The study of new material collected in the Monte León Formation (early Miocene), gave us the opportunity to describe four new species: Valdemunitella canui n. sp., Foveolaria praecursor n. sp., Neothoa reptans n. sp., and Calyptotheca santacruzana n. sp. Two of them (V. canui and C. santacruzana) were first recorded by F. Canu and interpreted as recent species from the Australian bryozoan fauna, but are herein described as new species. The stratigraphic range of Otionella parvula (Canu, 1904) is extended to the early Miocene. The present study emphasizes the close relationships between the South American Neogene bryozoan faunas and those of other Gondwanan sub-continents such as New Zealand and Australia.

Australasian pericomoids, psychodids resembling northern hemisphere species of Pericoma Walker (tribe Pericomini), are mostly members of the tribe Maruinini, here re-defined. Amongst Maruinini, they are like several neotropical genera named by Enderlein (1937), but their actual relationship to Enderlein's genera, and hence their identity, has been a long-standing taxonomic problem. Consideration of extensive new collections and observations made in the southern hemisphere now shows that they consist of the following: Genus Notiocharis Eaton. Tribe Maruinini: genus Didicrum Enderlein, and five new genera, Eremolobulosa, Rotundopteryx, Alloeodidicrurn, Satchellomyia and Ancyroaspis. Of these, the Australian Eremolobulosa is the possible sister group of the European Lobulosa Szabo, and the New Zealand genera Satchellomyia and Ancyroaspis are possible sister groups. Of Enderlein's neotropical genera, five classified by Quate (1963) as synonyms, or in one case a subgenus, of Pericoma (Didicrum, Desmioza, Synmormia, Syntomolaba and Podolepria) are recognised as full genera. A key to Australasian pericomoid genera is provided.

The type species of the genus Loricariichthys Bleeker, 1862, Loricariichthys maculatus (Bloch, 1794), is redescribed from two syntypes, one of which is designated the lectotype. The same specimen is also designated the neotype for Plecostomus cataphracta Gronovius (ed. Gray), 1854 (non Loricaria cataphracta Linnaeus, 1758, sensu stricto). The type locality of both nominal species is restricted after a comparison to specimens recently collected from a locality in Surinam.

A brief review of the movements of Alpine glaciers throughout the Holocene in the Northern Hemisphere (European Alps) and in the Southern Hemisphere (New Zealand Southern Alps) is presented. It is mainly based on glacier studies where 14C dating, dendrochronology and surface exposure dating with cosmogenic isotopes is used to establish the chronology of advances and retreats of glaciers. An attempt is made to draw some general conclusions on the temperature and climate differences between the Northern and Southern Hemisphere.

AbstractThe genusMycoblastusin cool temperate latitudes of the Southern Hemisphere is reviewed. Eight species are treated in detail:M. bryophilusImshaug ex Kantvilas sp. nov., from Campbell Island and Tasmania;M. campbellianus(Nyl.) Zahlbr.,M. coniophorus(Elix & A.W. Archer) Kantvilas & Elix comb. nov. andM. dissimulans(Nyl.) Zahlbr., all widespread across the austral region;M. disporus(C. Knight) Kantvilas comb. nov., from New Zealand and Tasmania;M. kalioruberKantvilas sp. nov, from Tasmania;M. sanguinarioidesKantvilas sp. nov., from Tasmania and south-eastern Australia; andM. leprarioidesKantvilas & Elix sp. nov., from south-eastern Australia (Victoria). Notes are provided on many other species ofMycoblastus, including those recognised for the Northern Hemisphere, and those originally described from austral regions but now excluded from the genus. Major characters of the genus are discussed, including thallus morphology and chemistry, apothecial pigments and ascus structure. It is suggested that the genus is heterogeneous and that some of its closest affinities may lie with the familyMegalariaceaeand the genusJapewia.
