The methods for estimating methane emissions from cattle as used in the Australian national inventory are based on older data that have now been superseded by a large amount of more recent data. Recent data suggested that the current inventory emissions estimates can be improved. To address this issue, a total of 1034 individual animal records of daily methane production (MP) was used to reassess the relationship between MP and each of dry matter intake (DMI) and gross energy intake (GEI). Data were restricted to trials conducted in the past 10 years using open-circuit respiration chambers, with cattle fed forage-based diets (forage >70%). Results from diets considered to inhibit methanogenesis were omitted from the dataset. Records were obtained from dairy cattle fed temperate forages (220 records), beef cattle fed temperate forages (680 records) and beef cattle fed tropical forages (133 records). Relationships were very similar for all three production categories and single relationships for MP on a DMI or GEI basis were proposed for national inventory purposes. These relationships were MP (g/day) = 20.7 (±0.28) × DMI (kg/day) (R2 = 0.92, P < 0.001) and MP (MJ/day) = 0.063 (±0.008) × GEI (MJ/day) (R2 = 0.93, P < 0.001). If the revised MP (g/day) approach is used to calculate Australia’s national inventory, it will reduce estimates of emissions of forage-fed cattle by 24%. Assuming a global warming potential of 25 for methane, this represents a 12.6 Mt CO2-e reduction in calculated annual emissions from Australian cattle.

ABSTRACT: In 2012, giant tiger shrimp Penaeus monodon originally sourced from Joseph Bonaparte Gulf in northern Australia were examined in an attempt to identify the cause of elevated mortalities among broodstock at a Queensland hatchery. Nucleic acid extracted from ethanol-fixed gills of 3 individual shrimp tested positive using the OIE YHV Protocol 2 RT-PCR designed to differentiate yellow head virus (YHV1) from gill-associated virus (GAV, synonymous with YHV2) and the OIE YHV Protocol 3 RT-nested PCR designed for consensus detection of YHV genotypes. Sequence analysis of the 794 bp (Protocol 2) and 359 bp (Protocol 3) amplicons from 2 distinct regions of ORF1b showed that the yellow-head-complex virus detected was novel when compared with Genotypes 1 to 6. Nucleotide identity on the Protocol 2 and Protocol 3 ORF1b sequences was highest with the highly pathogenic YHV1 genotype (81 and 87%, respectively) that emerged in P. monodon in Thailand and lower with GAV (78 and 82%, respectively) that is enzootic to P. monodon inhabiting eastern Australia. Comparison of a longer (725 bp) ORF1b sequence, spanning the Protocol 3 region and amplified using a modified YH30/31 RT-nPCR, provided further phylogenetic evidence for the virus being distinct from the 6 described YHV genotypes. The virus represents a unique seventh YHV genotype (YHV7). Despite the mortalities observed, the role of YHV7 remains unknown.

This study explores ecumenical activity of professor and bishop E. G. Gulin (1893 1975). Gulin was one of the key figures in the Finland s Evangelical Lutheran Church during the twentieth century. He was also one of the leading persons who imported ecumenical influences from abroad. However, unlike other churches, the Church of Finland did not recognise his importance. For example, in the 1950s Gulin was seen by the Anglicans as a future archbishop for the Evangelical Lutheran Church of Finland. Gulin s career as an ecumenist can be divided to three parts. Between 1917 and 1929, Gulin learned ecumenical working methods in Finland s World Student Christian Federation. He had a background in the revivalist movement, and his parents supported him in his studies. The Evangelical Lutheran Church did not originally play a major role for Gulin, although he was a member. Between 1930 and 1944, Gulin had more and more responsibility as a leading ecumenist in Finland. He became a member of Finland s ecumenical board, Yleiskirkollinen toimikunta. During the Second World War Gulin tried to solicit assistance for Finland s war effort at theological conferences, where Finnish theologians often discussed cooperation among Christians. A third period started in 1945, when Gulin became the bishop of Tampere. His new status in the Evangelical Lutheran Church placed him in a challenging position in ecumenical questions. He had responsibility for inter-church aid in Finland. He also participated in the World Council of Churches (WCC) assemblies in Evanston in 1954 and in New Delhi in 1961. Gulin s role was quite insignificant in those meetings. Closely related to Gulin s texts about ecumenism is kokemus, experience. Gulin wrote about his ecumenical experience or ekumeeninen kokemus. He believed that it was vital for the churches to appreciate their own experiences, since experience was the basis for further development. Yet Gulin mentioned very little about Christian dogma. The main reason seems to have been that he did not believe that a union between churches could be built on dogma.
