Oldest Australian vespertilionid (Microchiroptera) from the early Miocene of Riversleigh,Queensland

An upper molar of a small bat, here described from an early Miocene freshwater lime-stone deposit at Riversleigh, northwestern Queensland, is the oldest record in Australia of the microchiropteran family Vespertilionidae. The new taxon is referred to the cosmopolitan genus Leuconoe, but it does not appear to be closely related to the two extant Australian species of this genus.     

The charophyte Lamprothamnium succinctum as an environmental indicator: a Holocene example from Tom Thumbs Lagoon,eastern Australia

The palaeobiota from a middle to late Holocene succession in Tom Thumbs Lagoon, N.S.W., Australia, reflects a range of environmental conditions caused by sea-level changes and active estuarine sedimentation. At the base of the succession (～ ?0.4 m AHD) a thin bed, containing molluscs dated at 6.7 ka B.P. by radiocarbon and amino acid racemisation, and foraminifers is indicative of open estuarine conditions. From +0.35 m AHD towards the top of the sequence the charophyte Lamprothamnium succinctum occurs in subrecent deposits. This species is characterised here by statistical measurements, and new characters are described and illustrated. The charophytes record a drop in sea level and the establishment of a lower salinity artificial wetland. The investigation has also established that decalcification in charophytes can be related to acidification produced by the release of organic acids, aggravated after 1928 by anthropogenic pollution.     

SLEEPING ABROAD BUT WORKING AT HOME: CROSS‐BORDER RESIDENTIAL MOBILITY BETWEEN TRANSNATIONALISM AND (RE)BORDERING

Cross‐border residential mobility (CBRM) has so far largely been approached from a transnational perspective. However, recent developments in border studies and transnationalism give rise to certain doubts. While border studies have come to include mental borders next to physical borderlands, transnationalism today refers not just to cross‐border movements but also to identities trans‐cending the national. But border studies have shown that the increased crossing of borders is not necessarily coupled with their diminished significance. CBRM is a particularly interesting phenomenon as it entails the continuous crossing of a physical border, but the question is whether it also implies the erosion of mental borders and the emergence of transnational ties. While drawing on experiences from parallel cases, my study focuses on Poles from Szczecin moving just across the boundary to Vorpommern, Germany. Some are integrating there, but their large majority appears to carry on with everyday life in Poland as before moving. This settlement has triggered considerable resentment among local Germans, who as a reaction mark the borderland discursively and physically. As my survey shows, while both groups regularly cross the physical border, many even among the cross‐border residents consider it as a necessary dividing line or prefer cooperation to be reserved to some activities. Hence, unlike longdistance migration leading either to diaspora identities or to gradual dissolution in the majority culture, CBRM appears as a specific form of international migration where the physical proximity allows such intensive links with the country of origin that transnational effects are mitigated.
