Consensus among analysesindicated that Sericorniscomprises two primary lineagesof hithertounassociated species: S. beccarii with S.magnirostris, S.nouhuysi and the S. perspicillatusgroup; and S. papuensisand S. keriwith S. spiloderaand the S. frontalis group. Both lineages are shared by Australia and New Guinea. Patternsof latitudinal and altitudinal allopatry and sequencesof introgressiveintergradation are concordantwith these groupings,but many featuresof external morphologyare not. Apparent homologiesin face, wing and tail markings, used formerly as the principal criteria for grouping species,are particularly at variance and are interpreted either as coinherited ancestraltraits or homo- plasies. Distribution patternssuggest that both primary lineageswere first split vicariantly between

Homalopoa has diversified extensively in the Americas. Over half of the species in the supersection are diclinous; most of these are from the New World, while a few are from South-East Asia. Diclinism in Homalopoa can be divided into three main types: gynomonoecism, gynodioe- cism and dioecism. Here the sampling of species of New World Homalopoa is expanded to date its origin and diver- sification in North and South America and examine the evolution and origin of the breeding system diversity. Methods A total of 124 specimens were included in the matrix, of which 89 are species of Poa supersect. http://aob.oxfordjournals.org/ Homalopoa sections Acutifoliae, Anthochloa, Brizoides, Dasypoa, Dioicopoa, Dissanthelium, Homalopoa sensu lato (s.l.), Madropoa and Tovarochloa, and the informal Punapoa group. Bayesian and parsimony analyses were conducted on the data sets based on four markers: the nuclear ribosomal internal tanscribed spacer (ITS) and exter- nal transcribed spacer (ETS), and plastid trnT-L and trnL-F.

At how- by any plant family present, accurate estimate of the of Malesian orchid is difficult to make. ever, an number species Subtracting the numberofestablishedsynonyms from the numberof names attributed to Malesian orchid species results in the staggering figure of 6414 species, with a retention of 0.74. This is ratio (ratio of ‘accepted’ species to heterotypic names) undoubtedly a overestimate, of the 209 Malesian orchid have been revised gross as most genera never their entire from availablerevisions estimate realis- over range. Extrapolating to a more tic retention ratio is problematic due to the small number of modern revisions and the different of treated. If look for Malesian of nature the groups we comparison at species wide ofretention ratios: some recently revised groups, we encounter a range Bulbophylluw sect.

Correspondingly, we find a wide rangeof estimates for the ‘real’ numberof known Male- sian orchid species: from 2050 to 5125. Another approach would be to look at a single area, and to compute the retention ratio for the orchid flora of that area.

Photographer: Geoff North Island, South Island, Chatham Island (apparently absent from Walls Chatham Island now despite being formerly abundant). Also found in temperate Australia. HABITAT Coastal dunes; sandy and rocky places near the shore, especially foredunes and dune hollows. FEATURES Yellow-green tussocks up to about 70 cm tall. Leaves fine, rolled, somewhat drooping (coarser than silver tussock), initially green, often fading at tips to silver, and drying to golden-straw colour. Seed heads no longer than leaves; seeds relatively large, barley-like, leaving a characteristic zig-zag look to the remaining head when fallen. Flowers in early summer and the seed are produced in late summer. It could be confused with Poa chathamica which has blue- green or grass-green flat leaves and an open seed head which overtops the foliage. It could also be confused with marram grass which has similar foliage but large cat’stail-like seed heads which overtop the foliage. SIMILAR TAXA Ammophila arenaria (marram grass) is often confused with sand tussock because they grow in the same habitat.

Life history data on fire-specialists, including longevity, are needed to develop tools to assist fire management for conservation. We used skeletochronology to estimate the age of individuals of three South Australian fire-specialist lizard species: Amphibolurus norrisi (Agamidae), Ctenotus atlas (Scincidae) and Nephrurus stellatus (Gekkonidae).

    LEVEL 1 BIOLOGICAL ASSESSMENT OF RAVENSTHORPE GOLD PROJECT, WESTERN AUSTRALIA Page | 101 home ranges may overlap, there tends to be a smaller non-overlapping ‘core’ area defined by den locations. Core areas are approximately 4 km2 and 0.9 km2 for males and females, respectively (Serena & Soderquist, 1989). Females tend to be territorial, although some areas may be shared by a mother and her adult daughter (Serena & Soderquist, 1989). Male core areas are much larger and overlap broadly with other males as well as females. Both sexes occur at similar densities in the Jarrah forest. Home range size may be smaller in areas where foxes are effectively controlled, and where Chuditch population densities are higher (DEC, 2012b; Mathew, 1996). Chuditch are opportunistic feeders, foraging primarily on the ground at night. In the forest, insects and other large invertebrates comprise the bulk of their diet, though some mammals, birds and lizards are also included (DEC, 2012b; Serena et al., 1991). The Chuditch is primarily a nocturnal species, they may be diurnally active during the breeding season (April to July) or when cold, wet weather restricts nocturnal foraging (DEC, 2012b). The average life span of an established adult is two years, and wild Chuditch generally don’t live past four years (Soderquist, 1988). Factors contributing to Chuditch mortality include: ▪ Motor vehicle strike (Chuditch commonly forage along dirt roads and tracks making them more susceptible to this); ▪ Illegal shooting near roads; ▪ Predation by foxes, raptors and feral cats; ▪ Injury in rabbit traps; and ▪ Natural accidents and disease. The Chuditch has been recorded on camera within the Project Area during the two fauna surveys conducted by APM in 2016 and 2017.
