    THE OUTPUT OF SWARDS ON COMMERCIAL FARMS IN RELATION TO FERTILIZER AND OTHER MANAGEMENT FACTORS (1965)

    Notes: Survey data collected during a grassland-recording investigation showed a strong positive correlation between nitrogen input and the output of utilized starch equivalent per acre. At the levels of output covered, sward type was not very important in relation to total yield. Herbage species were important for other reasons and the choice of seeds mixtures should be determined by factors such as earliness and lateness of growth and resistance to disease and drought. The survey showed that well-managed ley and permanent pasture are both capable of producing at a high level. A disturbing feature of the results was the low production of most spring resowings, primarily as a result of poor management. Although the records were obtained from an above-average group of farms, the results have general application. Potential responses to fertilizers may be even greater on less intensive farms, especially with regard to phosphate and potash. However, the level of production of a field will always depend finally on the level of management exercised by the farmer himself.

    Reproducing Bobcats to Cumberland Island, Georgia (1993)

    Notes: Many felids are threatened by loss of habitat, lack of genetic diversity, and over-exploitation. The reintroduction of bobcats (Felis rufus) to Cumberland Island, Georgia provided an opportunity to reintroduce a mid-sized felid without the concern for species survival that is paramount with endangered species. We captured bobcats from the coastal plain region of Georgia, briefly held them in captivity, and released them on Cumberland Island. We describe and evaluate the protocols and techniques used to accomplish the reintroduction. Future reintroductions of felids should consider the problem of post-release dispersal, although our island was relatively isolated and inhibited dispersal. Also, any reintroduction effort should invest effort and resources into post-release monitoring of the population. Empirical knowledge about the effects of spatial distribution, genetics, population dynamics, especially mechanisms of population regulation, behavior, and environmental conditions on the viability of populations is critical to the conservation of endangered species. Future research of the bobcats on Cumberland Island will be able to address aspects of the population and genetic dynamics of a small, insular felid population.

    Ribosomal Dna Sequences of Encephalitozoon Hellem and Encephalitozoon Cuniculi: Species Identification and Phylogenetic Construction (1993)

    Notes: . A segment of ribosomal DNA, about 1,350 base pairs long, was amplified from the microsporidian species Encephalitozoon hellem, isolated from AIDS patients, and Encephalitozoon cuniculi. the amplified DNA segment extends from position 530 in the small ribosomal RNA subunit to position 580 in the large ribosomal RNA subunit. A comparison of sequence data from this region for Encephalitozoon hellem and Encephalitozoon cuniculi shows relatively high sequence similarity, supporting the placement of these two organisms in the same genus. At the same time, sequence differences between the two organisms confirm that they are not the same species. Three separate isolates of E. hellem were sequenced in the highly variable intervening spacer region. the sequence was identical for all three isolates. Within the amplified DNA segment, regions were sequenced which yield highly variable, moderately variable and highly conserved sequence information, appropriate for comparison with other species in the phylum Microspora at all taxonomic levels. We suggest that sequence data from these regions be included in future species descriptions for the purposes of species identification and phylogenetic analysis. Restriction digests of the amplified region are presented and give a rapid method for distinguishing between the two Encephalitozoon species.

    The Host-Restriction of Haemoproteus sp. indet. of the Wood-Pigeon Columba p. palumbus (1966)

    Notes: SYNOPSIS. Earlier experiments suggested that the species of Haemoproteus which infects English wood-pigeons (Columba p. palumbus) and is transmitted by the hippoboscid dipteran fly Ornithomya avicularia, was unable to infect Columba livia domestica, a host of H. columbae. This has now been confirmed by the injection of sporozoites into two pairs of pigeons, one of each species; in both experiments the C. palubus developed parasitemia while the C. livia did not. It has also been shown that this species of Haemoproteus can complete sporogony in a small proportion (2/73) of Pseudolynchla canariensis, the vector of H. columbae.

    The efficacy of a high magnesium grass cultivar in controlling hypomagnesaemia in grazing animals (1991)

    Notes: A cultivar of Italian ryegrass (Bb 2067), specifically bred for high magnesium content, was assessed for its efficacy in alleviating the incidence of hypomagnesaemia in lactating ewes. Pasture and animal management was regulated to maximize the potential for the development of hypomagnesaemia. The incidence of clinical hypomagnesaemia in ewes grazing the control pasture (cv. RvP) was 21% within the first 10 days and this was accompanied by a significant fall of 35% in serum magnesium concentration. The incidence in ewes grazing the high magnesium cultivar was only 2·5% and there was no significant change in the serum magnesium concentration.The mean magnesium content of Bb 2067 herbage (1·45 gkg DM-1) was 48% higher than cv. RvP (0·93 g kg DM-1) while calcium and phosphorus were 15% and 30% higher. The mean dry matter intake of ewes grazing Bb 2067 was higher than that of ewes grazing RvP, and although the difference was not statistically significant there were significantly increased intakes of magnesium, calcium and phosphorus for ewes grazing Bb 2067 compared with RvP. Ewes grazing Bb 2067 ingested more than the recommended allowance of magnesium and were close to sufficiency for calcium and phosphorus, while those grazing RvP were in serious deficit for all three minerals.There was no significant difference in the ewe body weight loss between the treatments but lamb liveweight gain was significantly greater on the Bb 2067 pastures compared with those on cv. RvP.It was concluded that the high magnesium grass provided an effective means of controlling hypomagnesaemia under grazing despite the extreme predisposing conditions imposed in this trial.

    A COMPARISON OF COCKSFOOT- AND TALL FESCUE-DOMINANT SWARDS FOR OUT-OF-SEASON PRODUCTION (1965)

    Notes: Swards based on a mixture of SI 70 tall fescue and S215 meadow fescue were very early in spring, gave high yields for conservation in mid-season and, rested from mid-August, gave good grazing in November-December. Under this treatment, the tall fescue assumed dominance, and the swards were persistent and remained productive. The digestibility of the tall fescue swards was always higher than that of swards based on cocksfoot with which they were compared. During spring and autumn the former sward was better grazed by stock, but the position was reversed in mid-summer. Cattle grazing tall-fescue-dominant swards made better liveweight gains than those grazing cocksfoot swards during November-December.

    A COMPARISON OF RYEGRASS VARIETIES FOR EARLY–BITE PRODUCTION (1965)

    Notes: The value of varieties of Italian, hybrid and Westerwold ryegrass for early-bite production was compared at 32 centres in different environments. The relative performance of Italian ryegrass varieties was fairly consistent from centre to centre over a period of 3 years. Danish and Leda Daehnfeldt Italians produced the most, and S22 the least, early spring production. Good early-bite and total annual yields were obtained from hybrid ryegrasses. Swards sown in the previous autumn were more winter-hardy than spring-sown swards and appeared to be as early in the following year.

    Notes: Early reproductive development in Lolium perenne L. has been widely used for defining growth stages in spring, and this has been useful in managing seed crops and in trials involving the use of growth retardants.A numerical scale for apical development based on morphological criteria, has been successfully used in research. The scale identifies eleven clearly recognizable stages of apical development, from the vegetative apex through to the immature, but completely-formed spike. It is intended that the key should be used to identify consistantly precise stages in apical development.
