The morphology and physiology of Eucalyptus camaldulensis seedlings grown from seed collected from two locations in the dry tropics, two in the humid tropics and two in semi-arid Northern Australia were compared in phytotron growth cabinets under well-watered and water-limited conditions and diurnal temperature ranges of 30-25 and 22-15�C. Seedlings from the two locations in each climate resembled each other more closely than they resembled seedlings from the other climates across the range of conditions tested. When water-limited, seedlings from the dry tropical and semi-arid climates had a higher allocation of dry matter to roots than seedlings from the humid tropics. However, those from the dry tropics shed their lower leaves and initiated small-leaved axillary shoots while those from the semi-arid climate retained their leaves and did not produce axillary shoots. In contrast, seedlings from the humid tropics responded by reduced gas (CO2 and H2O) exchange without changes in morphology or allocation of dry matter. These responses are appropriate for growth in each climate and are consistent with observations made on wild trees in the field, on trees in plantations overseas and also with data from seedlings grown in earlier glasshouse experiments.

Two new agraeciine genera and five new species are described from northern Australia. Both genera have species that live in mixed woodlands in the tropics. Armadillagraecia Rentz, Su, Ueshima, Robinson gen. nov. is known from two species in the Northern Territory and one from Queensland. Kapalgagraecia Rentz, Su, Ueshima, Robinson gen. nov. is known from two species, one apparently widespread in the Northern Territory, the other from Groote Eylandt, NT. Cytological data are provided for all Armadillagraecia species but not for Kapalgagraecia. A table is presented documenting knowledge of the known cytology of all Agraeciini. The calling songs of both A. mataranka and A. yerilla Rentz, Su, Ueshima, Robinson gen. et spp. nov. are noted and documented by sonograms. Known biological, ecological and distributional data are presented.

Cow reproductive rates, mortalities and liveweights, and steer growth rates from a herd of 500 Bos indicus - Bos taurus cross cows and their progeny were recorded over a period of 4 years from June 1981. The cattle grazed native pastures and were not supplemented. Cows which had a calf of more than 100 kg in June were allocated to 2 treatments: weaned and unweaned. Where the calf weighed less than this amount, cows were allocated to a separate 'young calf group. In the year following branding, weaning increased (P<0.05) conception rate from 73.9 to 93.8% and reduced (P<0.05) cow mortality rate from 14.1 to 4.5%, relative to the unweaned group. On average, weaned cows conceived 3 months earlier (P<0.05) than the other 2 groups, in November, and 27% of weaned cows subsequently calved out of season the following year, compared to 4% of the other groups. This affected subsequent weaning management by increasing the number of calves too young to wean in June. Weaned steers grew at a reduced (P<0.05) rate during the first year post-weaning. Despite compensatory gain in the next 2 years, they were still 26 kg lighter (P<0.05) than their unweaned counterparts at 3.5 years of age.

Three new species in the genus Niambia are described from southern African caves: N. botswanaensissp. nov. from Diviner’s Cave (Botswana), N. ghaubensissp. nov. from Ghaub Cave and N. namibiaensissp. nov. from Märchen Cave (Namibia). All these species show troglomorphic traits such as absence of body pigmentation and eyes. These are the first troglobitic species recorded in the genus. Most of the other species of Niambia are epigean and occur in semi-arid environments in the Afrotropical Region.

First Descriptions

The schizomid fauna of mainland Australia currently comprises 60 species within seven named genera, of which five are endemic to the continent: Attenuizomus Harvey, 2000, Brignolizomus Harvey, 2000, Draculoides Harvey, 1992, Julattenius Harvey, 1992, Notozomus Harvey, 2000. Most Australian schizomids have been described from eastern and northern Australia, but there is also a significant subterranean fauna that has been found in hypogean habitats in the semi-arid Pilbara region of Western Australia. The vast majority of these species can be assigned to the genus Draculoides and this study is the first in a proposed series to revise this highly diverse genus. We treat the species found in the western Pilbara region, which includes 13 new species and 13 previously named species, using morphological characters and multi-locus sequence data. We also incorporate a molecular “mini-barcode” approach for COI, 12S and ITS2 to diagnose the new species. The new species are named: Draculoides akashae Abrams and Harvey, n. sp., D. belalugosii Abrams and Harvey, n. sp., D. carmillae Abrams and Harvey, n. sp., D. christopherleei Abrams and Harvey, n. sp., D. claudiae Abrams and Harvey, n. sp., D. immortalis Abrams and Harvey, n. sp., D. karenbassettae Abrams and Harvey, n. sp., D. mckechnieorum Abrams and Harvey, n. sp., D. minae Abrams and Harvey, n. sp., D. noctigrassator Abrams and Harvey, n. sp., D. nosferatu Abrams and Harvey, n. sp., D. piscivultus Abrams and Harvey, n. sp. and D. warramboo Abrams and Harvey, n. sp. We also provide the first descriptions of males of D. anachoretus (Harvey, Berry, Edward and Humphreys, 2008) and D. gnophicola (Harvey, Berry, Edward and Humphreys, 2008). All of the new species are subterranean-dwelling, short-range endemic species that occur in regions subject to mining activities, rendering them of high conservation significance.

More than ten new species of colonial volvocine algae were described in world literature during recent years. In present review, the published data on taxonomy, geographical distribution and the species problem in this group of algae, mainly from the genera Gonium, Pandorina, Eudorina, and Volvox, are critically discussed. There are both cosmopolitan volvocalean species and species with local or disjunct distribution. On the other hand, the description of new cryptic taxa in some genera of the colonial family Volvocaceae, such as Pandorina and Volvox, complicates the preparation of a comprehensive review on their geography.

A New Species

A total of 14 species in seven tingid genera have been described from the mid-Cretaceous Burmese (Kachin) amber from northern Myanmar, with very distinct paleofauna. Here, a new species of a new genus, Burmavianaida anomalocapitata gen. et sp. nov., is described from Kachin amber. This new species can be readily distinguished from the other described tingid taxa by the apparently smaller body and the structures of the pronotum and hemelytron. Burmavianaida gen. nov. shares the diagnostic characters with two clades composed of three extant subfamilies (Cantacaderinae + Tinginae) and Vianaidinae and may represent an extinct clade distinct from them. To the best of our knowledge, B. anomalocapitata sp. nov. is the smallest species of Tingidae among over 2600 described species. Our new finding supports the hypothesis of the miniaturization phenomenon of insects in Kachin amber, as suggested by previous studies.

A New Species

We sampled two forms of Leptobrachium in syntopy at the type locality of L. pullum at upper elevations on the Langbian Plateau, southern Vietnam. The two forms differed in morphology (primarily in coloration), mitochondrial DNA, and male advertisement calls. One form closely agrees with the type series of L. pullum (but not to its original description due to error), and the other is described as new. Leptobrachium leucops sp. nov. is distinguished from its congeners by having small body size (males with SVL 38.8–45.2), the upper one-third to one-half of iris white, a blue scleral arc, a dark venter, and sexually active males without spines on the upper lip. Leptobrachium pullum and L. mouhoti, a recently described species from low-elevation slopes of the Langbian Plateau in eastern Cambodia, are morphologically divergent but genetically similar, warranting further investigation into geographic variation in the red-eyed Leptobrachium of southern Indochina.

Two new species of Terebrasabella Fitzhugh & Rouse, 1999 are described from eastern Australia. Terebrasabella hutchingsae sp. nov., was found from preserved coral rock debris collected in 1977 on the outer Barrier Reef near Lizard Island, Queensland. Terebrasabella fitzhughi sp. nov., was found alive in burrows in and among spirorbin serpulid tubes on intertidal rocks in Tasmania in 1996. Both species were found in mucoid tubes, and brood their young in a manner similar to the only other described species of Terebrasabella, T. heterouncinata Fitzhugh & Rouse, 1999. Terebrasabella hutchingsae sp. nov., is exceptional as it possesses a type of thoracic neurochaetal uncinus different from the other two species, and which is similar to the notochaetal acicular “palmate hook” seen in Caobangia. Descriptions of both species are given, and the diagnosis for Terebrasabella is emended. Larval and chaetal morphology and relationships among of the three known Terebrasabella spp. are discussed.
