Abstract Using the morphology of fin-winged fruits and accompanying foliage, the author characterizes a new fossil species, Dioscorea manchesteri Kvaček, sp. nov. (Dioscoreaceae), recovered from early Miocene deposits of the Most Basin (North Bohemia, Czech Republic). Dioscorea manchesteri matches the extant Dioscorea polystachya Turcz. in its fruit and foliage morphology. This perennial climbing vine native to China now grows throughout East Asia (Japan, Korea, Kuril Islands, Vietnam) in warm temperate to subtropical climate. The record of Dioscorea manchesteri is the first record of this genus in the European Neogene.

AbstractThe fossil record of Australasian Formicidae is extremely sparse. It currently comprises two ants in the subfamilies Ponerinae and Dolichoderinae from Plio/Pleistocene strata in Victoria, Australia, 14 as-yet undescribed ants from Cape York amber, and one ant in the subfamily Amblyoponinae from the early Miocene Foulden Maar in southern New Zealand. Here, we report on a diverse myrmecofauna preserved as compression fossils from Foulden Maar and describe Amblyoponinae gen. et sp. indet.,Rhytidoponera waipiatan. sp.,Rhytidoponera gibsonin. sp.,Myrmecorhynchus novaeseelandiaen. sp., andAustroponera schneiderin. sp. Further isolated wings are designated as Formicidae sp. A, B, and C, the former resembling a member of subfamily Dolichoderinae. Fossils ofAustroponeraandMyrmecorhynchusare reported for the first time, whereasRhytidoponera waipiatan. sp. andR.gibsonin. sp. are the first Southern Hemisphere fossil records of this genus.The fossil taxa from Foulden Maar establish the subfamilies Ectatomminae, Formicinae, Ponerinae and, possibly, Dolichoderinae in the Australasian region in the early Miocene and provide evidence that the few native ants in the extant New Zealand fauna are the surviving remnant of taxonomically different, possibly more diverse, warm-temperate to subtropical myrmecofauna.

A New Species

ABSTRACTAngiosperm wood from the Miocene Landslip Hill silcrete, Southland, New Zealand is described. It is characterised by solitary vessels of two distinct size classes; rays of two size classes alongside aggregate rays; simple perforation plates; and axial parenchyma in tangential bands up to three cells wide. The wood has features similar to Casuarinaceae and is described here as a new species, Casuarinoxylon ildephonsi. The fossils were collected as isolated fragments of wood; there is no directly associated cladode or cone material although isolated fragments of these are common elsewhere in the Landslip Hill silcrete. This is the second record of fossil Casuarinaceae wood from New Zealand and the first sample to be anatomically described. Currently, Casuarinaceae does not occur in New Zealand. Casuarinoxylon ildephonsi would have grown in a warm temperate to subtropical climate on an open deltaic floodplain.

The subtropical front (STF) generally represents a substantial oceanographic barrier to dispersal between cold-sub-Antarctic and warm-temperate water masses. Recent studies have suggested that storm events can drastically influence marine dispersal and patterns. Here we analyse biological and geological dispersal driven by two major, contrasting storm events in southern New Zealand, 2017. We integrate biological and physical data to show that a severe southerly system in July 2017 disrupted this barrier by promoting movement of substantial numbers of southern sub-Antarctic Durvillaea kelp rafts across the STF, to make landfall in mainland NZ. By contrast, a less intense easterly storm (Cyclone Cook, April 2017) resulted in more moderate dispersal distances, with minimal dispersal between the sub-Antarctic and mainland New Zealand. These quantitative analyses of approximately 200 freshly beach-cast kelp specimens indicate that storm intensity and wind direction can strongly influence marine dispersal and landfall outcomes.
