Species Being

This catalogue lists 139 species (in 12 orders, 26 families and 63 genera) of brown algae from New South Wales and Lord Howe Island. More than half (71) are endemic to Australia, with the remainder being very widely distributed (e.g. Europe, the Americas and Asia); 28 species have New South Wales type localities (14 from the mainland and 14 from Lord Howe Island). As a result of extensive searching of archival records, the exact locality of many 'Nov. Holl.' types is deduced to be the Sydney region of New South Wales. Four genera (Austronereia, Nemacystis, Nereia and Tomaculopsis) and 10 species are newly recorded, six species being new to the Australian continent. The largest genus represented is Sargassum, for which 37 species have been recorded, including 10 based on local types. Eleven of these Sargassum records are eliminated, the remaining 26 are in urgent need of regional monographic treatment. Eclipsed only by the Fucales (39 species in 9 genera), the order Dictyotales with 36 species in 13 genera, is the dominant group in terms of cover and possibly biomass along the mainland and at Lord Howe Island from low intertidal habitats to to depths of at least 35 m. In many areas of the seabed, brown algae and the cmstose corallines seem to be especially resilient to grazing by the sea-urchin Centrostephanis rodgersii which is presently besieging this coast.

Marine Algal

Fifteen species in seven genera of the marine benthic red algal order Gelidiales are reported from the New South Wales coast including Lord Howe Island and Norfolk Island. Critical sampling, a re-examination of herbarium specimens filed in the Royal Botanic Gardens Sydney and the University of Melbourne, and molecular sequencing of most of the species has determined that many of the previous identifications from this region of the Pacific were incorrect. Gelidium pusillum (Stackhouse) Le Jolis, once widely reported from this coast, is shown not to occur here and the specimens on which these misidentifications were made have proved to represent either new species or previously described species. Similarly, records of Gelidium australe J. Agardh have been found to represent misidentification of the formerly New Zealand endemic Gelidium allanii V.J.Chapman, and specimens identified as Gelidium caulacantheum J. Agardh actually represent the new species Gelidium hommersandii sp. nov. Previously recorded species verified in this study are Capreolia implexa Guiry & Womersley, Gelidiella acerosa (Forsskål) Feldmann & G.Hamel, Gelidium maidenii Lucas, Pterocladia lucida (Turner) J. Agardh, Pterocladiella caerulescens (Kützing) Santelices & Hommersand [as Pterocladia caerulescens (Kützing) Santelices], Pterocladiella capillacea (Gmelin) Santelices & Hommersand [as Pterocladia capillacea (Gmelin) Bornet], and Ptilophora pectinata (A. & E.S. Gepp) R.E.Norris. These species are described and illustrated in detail along with previously unreported reproductive structures. Three species are newly recorded for the New South Wales mainland [Parviphycus antipae Celan, Gelidium crinale (Turner) Gaillon, and Pterocladiella caloglossoides (Howe) Santelices], and two species (Gelidium isabelae W.R.Taylor and Gelidium allanii V.J.Chapman) represent new records for the Australian continent. In addition, three new species are described: Gelidium bernabei sp. nov., Gelidium declerckii sp. nov., and Gelidium hommersandii sp. nov.

The marine benthic green macroalgae of the New South Wales mainland and of Lord Howe Island are listed, each with bibliographic, distributional and specimen-voucher details. Included are 113 species in 9 orders, 14 families and 38 genera, of which 12 species are based on New South Wales types. With respect to biodiversity, New South Wales is as rich in numbers of genera and species as southern Australia. Eight genera (Pedobesia, Boodlea, Neomeris, Trichosolen, Ventvicaria, Caulerpella, Pseudochlorodesmis, Sporocladopsis) and 41 species are new records for the State, and 14 species are newly recorded for the Australian continent. The largest genus represented is Cladophora; 22 species are recorded, 13 from Lord Howe Island alone, and 7 are new to Australia (C. cymopoliae, C. colabense, C. dotyana, C. nigrescens, C. ohkuboana, C. patentirainea, C. ryukyuensis). Examination of type and recently collected material of Caulerpa annulata (from Port Arthur, Tasmania) shows it to be synonymous with the earlier Caulerpa hodgkinsoniae (from Ballina, New South Wales).

Species Being

Yellow-footed Rock-wallabies (YFRW) Petrogale xanthopus have declined in numbers since European settlement from past hunting for skins, habitat disturbance and predation and competition with feral animals (Gordon et al. 1978, 1993; Copley 1983; Henzell 1990). This has led to the species being classed as potentially vulnerable to extinction in Australia (Kennedy 1992), and endangered in New South Wales (Schedule 1, Threatened Species Conservation Act, 1995).

The Family

Four new species of the family Thanerocleridae are described from Australia (Queensland, New South Wales): Isoclerus (Isoclerus) rumcajs, I. (I.) manka, I. (I.) cipisek and I. (I.) gerstmeieri. These species are the first records of the family’s autochthonous members from the Australian continent. The subgenus Isoclerus (Lyctosoma) Lewis is synonymised with Isoclerus (Isoclerus) Lewis. Hypotheses concerning the biogeography of subtribe Isoclerina Kolibáÿč in which the newly described species belong, are proposed. The ancestral area of Isoclerina may be in Africa or somewhere in the region of Europe, Greenland and the eastern part of North America – in either case, in the Lower to Middle Cretaceous era. Also, pan-biogeographic hypotheses are formulated for the distribution patterns of species of the subgenus Isoclerus.

A Site

Aerial photography was used to estimate the representation of shallow subtidal habitats in New South Wales. Sixty sites, each between 4 and 5 hectares, were mapped with Geographical Information Systems software using ortho-rectified images digitized from 1:8000-scale photographs and ‘ground truthed’ in the field by divers. Barrens habitat covered an estimated 50% (s.e. = 3.9) of nearshore reefs between Port Stephens and Disaster Bay. Coverage of barrens habitat was greatest in Disaster Bay (68%, s.e. = 6.7) and least south of Disaster Bay (1%, s.e. = 0.3). There were clear differences among localities in the area of reef within the mapped sites; those at Cape Howe, Nadgee, and Turingal were significantly smaller in area than all others. There was no clear latitudinal trend in these differences but there was evidence of sand inundation at a site at Nadgee, where the reef was small. Differences in the densities and size-structure of the sea urchin Centrostephanus rodgersiiat 27 of the mapped sites provide a basis for testing relationships between the demography of this species and the persistence of the barrens habitat. The extensive coverage of the barrens habitat in New South Wales is likely to limit the productivity of the abalone industry. The development of a sea urchin fishery may have large impacts on habitat representation on nearshore reefs.
