AbstractPhytoliths in the modern vegetation of sub-Antarctic Campbell Island are compared with those in the soil beneath to assess the accuracy of vegetation reconstructions made from dispersed phytolith assemblages. The soil phytoliths alone suggest the source vegetation is a grassland association for all study sites, which reflects none of the herb, fern or shrub component of the overlying vegetation. It is concluded that at this locality dispersed phytoliths on their own are not reliable indicators of source vegetation and should be used with caution in this context for palaeoecological studies. However, they can provide useful botanical information where all other organic material is absent. With further research, based on the abundance and diversity of Poaceae phytoliths observed in this and other studies, dispersed phytoliths from the fossil record have the potential to contribute significantly to the understanding of grassland ecosystem development in the geological past.

Abstract A description is provided for Endophragmiella pinicola, which colonies are found on dead decaying leaves, twigs and cones of conifers, occasionally on other substrata, very often in association with other fungi, effuse, greyish-brown. Information is included on geographical distribution (USA (Alabama, Kentucky and Tennessee), Campbell Island, India (Himachal Pradesh), New Zealand, Czech Republic, France, UK and Ireland), hosts (Abies alba, Cedrus deodara, Myriophyllum spicatum, Picea sitchensis, Picea sp., Pinus montezumae, P. nigra, P. radiata, P. sylvestris, P. thunbergii, P. torreyana, Pinus sp. and Taxus cuspidata), biology and conservation status.

The Australian and New Zealand species of Clinocera Meigen are revised. Clinocera gressitti Smith is known from Campbell Island (New Zealand) and the following seven new species are recognised from eastern Australia: C. australiana, sp. nov., C. bickeli, sp. nov., C. irrorata, sp. nov., C. monticola, sp. nov., C. queenslandica, sp. nov., C. rubriventris, sp. nov. and C. spinosa, sp. nov. All species are described and illustrated. A key to species of Clinocera from Australia and New Zealand is provided and phylogenetic relationships and biogeographic patterns are discussed.

Future Population

AbstractPopulations of grey petrels have declined globally due to both incidental capture in commercial fisheries and predation by introduced mammals at breeding sites. In the New Zealand region, grey petrels only breed on Campbell and Antipodes islands. Rats were successfully eradicated from Campbell Island in 2001. We assessed the spatial extent and conducted the first quantitative population estimate of the grey petrel population on Campbell Island and surrounding islets. There was an estimated c. 96 pairs (95% CI: 83, 109) of breeding grey petrels from the four colonies. Since work was conducted during the middle of the chick-rearing stage, this is an underestimate of the breeding population. The Campbell Island grey petrel breeding population remains small. Our study provides a baseline for future population estimates of grey petrels on Campbell Island.

Although feral horses are a common management problem in numerous countries, detailed and long-term demographic studies are rare. We measured the age and sex structure, and pregnancy, birth and death rates in a population of 413 feral horses in New Zealand during 1994–98 and used them to construct a model simulating population growth. Survivorship increased with age (0–1 years old = 86.8%, 1–2 = 92.3%, 2–4 = 92.4%, ≥�4 years old = females 94%, males 97% per annum). Birth sex ratio parity, a slight female bias in the adult sex ratio (92 males per 100 females) and higher adult male survivorship indicated lower average survivorship for young males than females that was not detectable in mortality statistics. Pregnancy and foaling rates for mares ≥�2 years old averaged 79 and 49%, respectively. Foaling rates increased as mares matured (2–3-year-old mares = 1.9%, 3–4 = 20.0%, 4–5 = 42.1%, ≥�5 = 61.5% per annum). Young mares had higher rates of foetal and neonatal mortality (95% of pregnancies failed and/or were lost as neonatal foals in 2–3-year-old mares, 70.6% in 3–4, 43.2% in 4–5, and 31% in mares ≥�5 years old). Population growth was 9.6% per annum (9.5–9.8, 95% CI) without human-induced mortalities (i.e. r = 0.092). Our model, standardised aerial counts, and historical estimates of annual reproduction suggest that the historical sequence of counts since 1979 has overestimated growth by ~50% probably because of improvements in count effort and technique.

AbstractThe genusMycoblastusin cool temperate latitudes of the Southern Hemisphere is reviewed. Eight species are treated in detail:M. bryophilusImshaug ex Kantvilas sp. nov., from Campbell Island and Tasmania;M. campbellianus(Nyl.) Zahlbr.,M. coniophorus(Elix & A.W. Archer) Kantvilas & Elix comb. nov. andM. dissimulans(Nyl.) Zahlbr., all widespread across the austral region;M. disporus(C. Knight) Kantvilas comb. nov., from New Zealand and Tasmania;M. kalioruberKantvilas sp. nov, from Tasmania;M. sanguinarioidesKantvilas sp. nov., from Tasmania and south-eastern Australia; andM. leprarioidesKantvilas & Elix sp. nov., from south-eastern Australia (Victoria). Notes are provided on many other species ofMycoblastus, including those recognised for the Northern Hemisphere, and those originally described from austral regions but now excluded from the genus. Major characters of the genus are discussed, including thallus morphology and chemistry, apothecial pigments and ascus structure. It is suggested that the genus is heterogeneous and that some of its closest affinities may lie with the familyMegalariaceaeand the genusJapewia.
