The evolution of novel traits ("key innovations") allows some lineages to move into new environments or adapt to changing climates, whereas other lineages may track suitable habitat or go extinct. We test whether, and how, trait shifts are linked to environmental change using Triodiinae, C4 grasses that form the dominant understory over about 30% of Australia. Using phylogenetic and relaxed mol...

As part of a large-scale search for coherent pulsations from LMXBs in the RXTE archive, we have completed a detailed series of searches for coherent pulsations of 4U 1820−30 — an ultracompact LMXB with a binary period of 11.4 min, located in the globular cluster NGC 6624. The short binary period implies any coherent signal would be highly accelerated, so we used phase modulation searches, orbit...

The higher level relationships within Apiaceae (Umbelliferae) subfamily Apioideae are controversial, with no widely acceptable modern classification available. Comparative sequencing of the intron in chloroplast ribosomal protein gene rpl16 was carried out in order to examine evolutionary relationships among 119 species (99 genera) of subfamily Apioideae and 28 species from Apiaceae subfamilies...

We studied White-winged Fairy-wrens ( Malurus leucopterus edouardi ) on Barrow Island (20°43 ′ S, 115°28 ′ E) during September and October 1998. Birds were most abundant (occurring every 1–2 ha of habitat) on ridges in upland areas where Triodia wiseana was the dominant vegetation and was interspersed with open areas. They were less abundant in foredune areas and on red dunes, and were rare in ...

Background: Six ethnographic museum resins with documented adhesive, medicinal and narcotic uses have been analysed by gas chromatography–mass spectrometry (GC-MS) as a step towards understanding the role of specific resins in 20 century Australia and New Guinea. Curated in the Pitt Rivers Museum for over a hundred years, these specimens are examples of resin used for three different purposes, ...

We present the analysis of simultaneous X-ray (RXTE) and radio (VLA) observations of two atoll-type neutron star X-ray binaries: 4U 1820–30 and Ser X-1. Both sources were steadily in the soft (banana) X-ray state during the observations. We have detected the radio counterpart of 4U 1820–30 at 4.86 GHz and 8.46 GHz at a flux density of ∼ 0.1 mJy. This radio source is positionally coincident with...

Sobre el pronunciamiento de Riego en enero 1820 y sobre Trienio Liberal que le siguió no existía una obra especializada como la ahora ofrecen los historiadores Rújula Chust. Su narrativa se enmarca entre rebelión Las Bocas San Juan Manifiesto Fernando VII 1.º octubre 1823. En esa ocasión rey suspendió Constitución anuló lo realizado por gobiernos liberales desde 7 marzo 1820.
