Title: Serendipity during long-term monitoring of translocation trials Abstract: Abstract: An essential component of all translocation projects is the monitoring of outcomes and evaluation of processes after planting has taken place. Monitoring goals and objectives are usually formulated early in the translocation planning process based on available knowledge of the species' biology and ecology. However, nature is rarely predictable, and occasionally unexpected and even surprising observations can be made during the course of long-term monitoring that may be missed altogether in the short-term. Such serendipitous observations may be readily explainable, or may lead to further experimentation or extended monitoring in order to understand their underlying mechanisms. I have experienced several examples of such serendipity in the course of long-term monitoring of translocation trials in South Australia, and will briefly discuss four of them here. None of these outcomes were predicted to occur in the way they did when the translocation trials were first planned or set up, and each one was revealed only after a significant period of consistent and regular monitoring.

Title: Youngest reported radiocarbon age of a moa (Aves: Dinornithiformes) dated from a natural site in New Zealand Author: Rawlence, Nicolas James; Cooper, Alan Abstract: The extinction date of the giant flightless New Zealand ratite bird, the crested moa (Pachyornis australis), is of considerable interest because the youngest verified remains are dated to the Pleistocene–Holocene transition c. 10,000 yr BP, which was characterised by severe climatic and habitat change, and are considerably earlier than the late Holocene extinctions of the other eight moa species. Analysis of a partial crested moa skeleton (NMNZ S23569) from Castle Keep Entrance, Bulmer Cave System, Mount Owen, South Island, generated a radiocarbon date of 564±26 yr BP (544–508 cal yr BP; 95.4% AD 1396–1442). As a result the Bulmer Cave specimen represents the youngest moa yet found from a natural site in New Zealand. Combined with additional crested moa remains dated to the late Holocene from Cheops Cave (Mount Arthur) and Magnesite Quarry (Cobb Valley), this indicates that crested moa did not go extinct during the Pleistocene–Holocene transition but survived until after Polynesian colonisation in c. AD 1280. The new radiocarbon dates reported here have important implications for the timing of moa extinction and the late survival of moa in alpine areas of New Zealand.

Title: Challenging species delimitation in Collembola: cryptic diversity among common springtails unveiled by DNA barcoding Author: Porco, David; Bedos, A.; Greenslade, Penelope; Janion, C.; Skarżyński, D.; Stevens, Mark Ian; van Vuuren, Bettine Jansen; Deharveng, Louis Abstract: Collembola is one of the major functional groups in soil as well as a model taxon in numerous disciplines. Therefore the accurate identification of specimens is critical, but could be jeopardised by cases of cryptic diversity. Several populations of six well characterised species of springtails were sequenced using the COI barcode fragment as a contribution to the global Collembola barcoding campaign. Each species showed high intraspecific divergence, comparable to interspecific sequence divergence values observed in previous studies and in 10 congeneric species barcoded here as a reference. The nuclear marker, 28S, confirmed all the intraspecific lineages found with COI, supporting the potential specific status of these entities. The implications of this finding for taxonomy and for disciplines relying on species names, such as evolution and ecology, are discussed.
