Copper deficiency in sheep and cattle continues to occur in the cereal-pasture zones of South Australia (Cunningham 1974; Hannam and Reuter 1977) even though remedial measures are well known. To examine possible causes, two surveys were undertaken involving the collection and chemical analysis of a wide range of cruciferous plant species and companion pasture legumes (principally annual Medicago species). Plant samples were analysed for copper and for the elements sulfur, cadmium, molybdenum and zinc, which are known to interact with copper in the diets of ruminants. The crucifers had on average lower copper, but far higher concentrations of total sulfur, sulfate sulfur and cadmium than the companion legume species. Concentrations of zinc and molybdenum were similar for both plant groups. The survey data suggest that diets containing appreciable quantities of cruciferous species could induce copper deficiency in ruminants.

Field experiments are described comparing a wide range of annual, winter-growing legume species with regard to their grain yield and protein content in South Australia. In 1974, a year when rainfall was considerably above average, Vicia faba (fieldbeans) outyielded all other species at each of two sites, eighty lines producing a mean yield of 8.2 t ha-1 of air-dry grain. In 1975, when rainfall was again generally above average but poorly distributed, V. faba, V. sativa and certain Lathyrus species yielded well, while other crops maintained average yields or failed in specific environments. The relative merits of new crop species in the diversification of rotations in dry land farming are discussed and it is concluded that field beans could be developed rapidly into a valuable alternative grain crop.

An ecogeographic survey was conducted in six key agricultural zones in Morocco to study the relationship between the natural distribution of medic species and soil and climatic measurements. At each of the 161 sites visited, the presence of medic species was recorded, and soil samples collected. Climatic data were obtained from published records. The influence of soil factors on the presence of medic species was more important than that of climate. With the exception of M. truncatula and M. minima, there were significant soil differences between sites where a species was present and sites where it was absent. Only 5 of the 11 medic species recorded were affected by one or more of the three climatic factors considered. Medics were found most frequently on sites where minimum temperature range was 3-7�C, pH 6.6-7.5, and with the exception of M. littoralis and M. laciniata, maximum temperature 30-35�C and rainfall 300-600 mm. M. truncatula was widespread and tolerant of a wide range of edapho-climatic conditions. It was concluded that this well studied species should be given higher priority in future evaluation programs.

Termination by tillage is one strategy used for regenerating pasture stands. Yet, research gaps exist on how tillage affects carbon (C) and nitrogen (N) forms and amounts in western Canadian soils. We measured total soil organic C (SOC), dissolved organic C (DOC), total dissolved N (TDN), light fraction organic C (LFOC) and N (LFON), microbial biomass C (MBC) and N (MBN), and inorganic N as indicators of soil organic matter (SOM) dynamics. After tillage termination in fall 2018, we sampled soils (0‒10cm; 0‒15cm) under three legume species (alfalfa, cicer milkvetch and sainfoin) three times (spring, summer and fall of 2019) across three landscape positions. Legume species did not affect the measured parameters. Over time, tillage affected DOC, TDN, and inorganic N. Averaged across three pasture legumes and three landscape positions, tillage increased DOC 29% by summer. Fall-applied tillage led to 59% and 33% higher TDN in the succeeding summer and fall. Inorganic N increased by 14% and 40% across landscape positions and sampling after tillage. Averaged across landscape positions, MBC decreased by 31% from spring to summer and increased by 51% from summer to fall. However, MBN increased by 53% and decreased by 5% within the same period. The seasonal fluctuations in MBC/MBN reflected variations in moisture, temperature, and substrate quality. Total SOC, LFOC, and LFON increased on the upper slopes and fall sampling time. Although single intensive tillage did not affect total SOC, several tillage operations could accelerate SOM loss and reduced total C storage over time.

Ghorkhod Protected Area (GPA) is located in a transitional zone among different biogeographical units in North Khorassan Province, NE Iran. The study area is mainly a mountainous region in western extensions of Khorassan-Kopet Dagh floristic province. We investigated the floristic composition, life form spectrum and phytogeography of the study area through several random collection efforts and 200 vegetation samples (reléves) in selected vegetation types during 2007–2012. A total of 663 vascular plant species belonging to 367 genera and 81 families are recorded as native and naturalized in GPA. Angiosperms and Dicots are among the most diverse plant groups. The richest plant families are Asteraceae (88 species), Poaceae (78), Lamiaceae (45), Brassicaceae (43), Fabaceae (38), and Caryophyllaceae (32). The genera Allium L. (17 species), Astragalus L. (15) and Cousinia Cass. (12) are the richest ones, however, the majority of the species belongs to oligotypic and monotypic genera. Life form spectrum of the study area is dominated by hemicryptophytes (38.9%) and therophytes (23.4%). Allium transvestiens Vved., Agropyron desertorum Schult., Helictotrichon turcomanicum Czopanov and Piptatherum latifolium (Roshev.) Nevski are recorded as new to Iran. The core flora of the area has the Irano-Turanian origin. However, the wide-range and widespread elements are also well represented in the study area. GPA is inhabited by several endemic, rare and narrow-range plant species, indicating the biodiversity importance of the study area in NE Iran.

Kids and the Scary World of Video In MIA 42, November 1986, page 70, in Book Reviews & Magazines & Journals, incorrect information was published. Any inconvenience this may have caused is regretted. Let's get it right this time! The South Australian Council for Children's Films & Television produced KIDS and The Scary World of Video - a 200-page report which costs $18.50 (including postage within Australia, less for multiple copies). For overseas orders, SACCFT will, unfortunately, have to charge for postage. For further information, telephone or write to Ms Felicity Coleman, SACCFT Inc., 181 Goodwood Road, Millswood 5034. Telephone: (OS) 373 0282. We reprint Henry Mayer's review from MIA 42:70, November 1986: This careful study of video viewing among 1,498 primary school children in South Australia looks both at children and parents. It shows that access to videos, considered in more controlled circumstances as unsuitable, is easy through a wide range of sources. Over a third reported seeing videos containing extreme violence and horror, including mutilation and dismemberment. The children are affected and report scenes they would like to but cannot forget. A smaller number report a desire to continue to remember scenes of striking violence. Sixty-one per cent had a VCR at home and 85.7% reported watching tapes at a friend's home. The report includes very detailed extracts from the responses. It is by far the most careful study yet of access and responses to content, with proposals for action.

Pyrite is the most common sulphide in a wide range of ore deposits and well known to host numerous trace elements, with implications for recovery of valuable metals and for generation of clean concentrates. Trace element signatures of pyrite are also widely used to understand ore-forming processes. Pyrite is an important component of the Olympic Dam Cu–U–Au–Ag orebody, South Australia. Using a multivariate statistical approach applied to a large trace element dataset derived from analysis of random pyrite grains, trace element signatures in Olympic Dam pyrite are assessed. Pyrite is characterised by: (i) a Ag–Bi–Pb signature predicting inclusions of tellurides (as PC1); and (ii) highly variable Co–Ni ratios likely representing an oscillatory zonation pattern in pyrite (as PC2). Pyrite is a major host for As, Co and probably also Ni. These three elements do not correlate well at the grain-scale, indicating high variability in zonation patterns. Arsenic is not, however, a good predictor for invisible Au at Olympic Dam. Most pyrites contain only negligible Au, suggesting that invisible gold in pyrite is not commonplace within the deposit. A minority of pyrite grains analysed do, however, contain Au which correlates with Ag, Bi and Te. The results are interpreted to reflect not only primary patterns but also the effects of multi-stage overprinting, including cycles of partial replacement and recrystallisation. The latter may have caused element release from the pyrite lattice and entrapment as mineral inclusions, as widely observed for other ore and gangue minerals within the deposit. Results also show the critical impact on predictive interpretations made from statistical analysis of large datasets containing a large percentage of left-censored values (i.e., those falling below the minimum limits of detection). The treatment of such values in large datasets is critical as the number of these values impacts on the cluster results. Trimming of datasets to eliminate artefacts introduced by left-censored data should be performed with caution lest bias be unintentionally introduced. The practice may, however, reveal meaningful correlations that might be diluted using the complete dataset.

Foliar symptoms of copper deficiency shown by five tropical and five temperate pasture legumes are described. The descriptions are sufficiently diverse to permit individual treatment. The more succulent species showed severe chlorosis and necrosis of leaves, whereas the less succulent ones showed chlorosis followed by leaf abscission and little necrosis. Species within a genus developed somewhat similar symptoms. The initial symptoms of copper deficiency in the Trifolium species in particular were wilting and partial dehydration. The implications of copper deficiency on wilting are discussed.

An improved technique for successful artificial hybridization in annual medic (Medicago spp.) is described. Using a previously reported method, only four out of seven species were successfully crossed, with the percentage of success ranging from 3 to 22%. Initial modifications to this technique gave a 7-8 fold increase in the successful crossing rate in M. murex and M. polymorpha medic, from 9 to 64% with M. murex and from 10 to 82% with M. polymorpha. Further modifications to the technique resulted in a success rate of 100% in both species. The numbers of seeds per pod obtained from crosses in both species were also increased by using the modified techniques compared to the established method. Selection of larger, more mature flowers, differences in flower cutting position, as well as post pollination position were the main modifications which accounted for the greatly improved success rate. The modified technique was subsequently applied successfully to obtain for the first time inter-specific crosses involving M. polymorphax M. murex, M. polymorphax M. sphaerocarpos, M.murexx M. sphaerocarpos, M. solerolii x M. littoralis/M.truncatula hybrid, M. solerolii x M, tornata, and M. littoralis/M.truncatula hybrid x M. sphaerocarpos.
