Corals are associations of millions polyps that live in symbiotic way with zooxanthellae algae. Most of the polyps live in colonies and form a reef. Coral reefs are rich ecosystems that contain diverse organisms living in it. However, the threat of damage increases with the pressure that enters the waters. Coral transplantation is one way of restorations that can be done to restore damaged corals by cutting live corals and then planting them in places where the corals have been damaged. This study aims to determine the growth rate of Acropora formosa corals that were transplanted on fixed and hanging media. Data was collected in Malalayang Coast Waters, Manado City, North Sulawesi. The research took place for seven months. Beginning with the coral transplant activity of Acropora formosa on fixed and hanging media, then continued with monitoring every month for six months. Transplanted corals were measured using a ruler to determine the length of the coral from the beginning to the end of the study and then the data was analyzed using Microsoft Excel. The results obtained for the average growth rate of Acropora formosa corals transplanted on fixed media were 0.8 cm and on hanging media 1.8 cm. Overall growth rate averaged 1.3 cm.Keywords: Coral, Coral Reef, Transplant, Acropora formosa.

Salah satu pulau di Taman Nasional Karimunjawa yang sering dikunjungi wisatawan adalah Pulau Menjangan Kecil. Wisatawan tertarik mengunjungi Pulau Menjangan Kecil dikarenakan keanekaragaman ekosistemnya, terutama ekosistem terumbu karang dan letaknya yang dekat dengan pulau utama. Namun, aktivitas pariwisata tersebut menyebabkan terjadinya degradasi ekosistem terumbu karang. Tujuan dari penelitian ini adalah untuk mengetahui kondisi fisika kimia perairan, tutupan terumbu karang dan jenis karang yang hidup di titik pengamatan , laju pertumbuhan karang dan korelasi antara variabel fisika kimia perairan terhadap laju pertumbuhan terumbu karang. Metode penelitian menggunakan metode eksplanatif dan dianalisa menggunakan SPSS 23 dan Microsoft Excel 2013. Hasil yang diperoleh adalah kualitas perairan di lokasi tersebut mendukung pertumbuhan ekosistem terumbu karang dengan suhu yang berkisar 27-300C, kecerahan sampai dasar dan salinitas sebesar 35 ppm. Tutupan terumbu karang di titik pengamatan tergolong baik dengan persentase penutupan sebesar 61,92%. Jenis karang yang dominan adalah jenis Acropora formosa dan Acropora divaricata. Laju pertumbuhan karang yang diukur adalah jenis Acropora formosa dengan nilai sebesar 5,47 mm/bulan. Berdasarkan nilai R2 pada grafik rata-rata laju pertumbuhan terumbu karang, waktu pengukuran memiliki pengaruh sebesar 95,1 % terhadap laju pertumbuhan karang. Hasil uji Pearson menunjukkan variabel fisika kimia perairan yang memiliki hubungan terhadap laju pertumbuhan terumbu karang adalah arus dan pasang surut air laut dengan nilai Sig. 0,027<0,05 dan Sig. 0,046<0,05. Temperatur air laut tidak memiliki korelasi terhadap laju pertumbuhan terumbu karang dengan nilai Sig. 0,364>0,05.  One of the islands in Karimunjawa National Park that often visited by tourists is the Menjangan Kecil Island. Tourists are interested to visit Menjangan Kecil Island because the diversity, especially the coral reef ecosystem and its location that close to the main island. However, these tourism activities cause degradation of coral reef. The purpose of this study was to determine the physical chemistry of the waters, coral reef cover and the types of coral, the growth rate of coral and the correlation between the variables of physical chemistry of the waters on the growth rate of coral reefs. The research method used explanatory method and analyzed using SPSS 23 and Microsoft Excel 2013. The quality of water in these locations supported the growth of coral reef ecosystems with temperatures ranging from 27-300C, brightness to base and salinity of 35 ppm. Coral reef cover at the observation point is classified as good with a closing percentage of 61.92%. The dominant coral species are Acropora formosa and Acropora divaricata. The measured coral growth rate was Acropora formosa with a value of 5.47 mm / month. Based on the R2 value on the graph of the average growth rate of coral reefs, the measurement time has an influence on the growth rate of the coral. The results of Pearson's test showed that the physics of water chemistry variables that have a relationship to the growth rate of coral reefs are currents and tides with the value of Sig. 0.027 <0.05 and Sig. 0.046 <0.05. Sea water temperature does not have a correlation to the growth rate of coral reefs with the value of Sig. 0.364> 0.05.

The minimum size of coral transplants, Acropora formosa, was assessed to support their survival and growth. For this, 150 coral fragments of different sizes (5, 10, 15 cm) were transplanted close to the donor colony. Their survivorship and growth were observed for 12 months. At the end of the observation time, 90% of 15 cm-transplanted coral fragments survived, while the others (10cm and 5 cm) did 86% and 82% respectively. The average growth rate of 5 cm-coral fragments was 0.860 cm/month, while 10 and 15 cm-fragments were 0.984 cm/month and 1.108 cm/month respectively. One-way ANOVA showed that there was significant difference (p<0.05) among the three (5, 10, 15 cm) transplant initial sizes in which the longest fragment size tended to survive longer than the smaller one.  However, the smaller transplants grew better than the bigger one, 10.318 cm/year (206%) for 5 cm-transplant, 11.803 cm/year (118%) for 10 cm-transplant, and 13.299 cm/year (89%) for 15 cm-transplant, respectively. Ukuran minimal fragmen karang Acropora formosa yang ditransplantasi diduga untuk mendukung ketahanan hidup dan pertumbuhannya. Untuk itu, 150 fragmen karang ditransplantasi ke lokasi yang berdekatan dengan koloni induknya.  Ketahanan hidup dan pertumbuhan semua fragmen karang yang ditransplantasi diamati selama 12 bulan.  Pada akhir pengamatan, 90% dari fragmen karang berukuran 15 cm yang ditransplantasi dapat bertahan hidup, sedangkan yang lainnya (ukuran 10 cm dan 5 cm) masing-masing sebesar 86% dan 82%.  Rata-rata laju pertumbuhan fragmen karang dengan ukuran awal 5 cm adalah 0,860 cm/bulan, sedangkan ukuran fragmen 10 dan 15 cm masing-masing adalah 0,984 cm/bulan and 1,108 cm/bulan. ANOVA satu arah menunjukkan adanya perbedaan yang nyata (p<0.05) antara ketiga ukuran fragmen yang berbeda, di mana ukuran fragmen karang yang lebih panjang cenderung mempunyai ketahanan hidup yang lebih baik. Namun demikian, ukuran transplant yang lebih kecil memiliki pertumbuhan lebih baik dibandingkan dengan ukuran yang lebih besar, yakni10,318 cm/tahun (206%) untuk transplant berukuran 5 cm, 11,803 cm/tahun (118%) untuk 10 cm, dan 13,299 cm/tahun (89%) untuk ukuran 15 cm.

Lamb Growth

Lamb growth, carcass and pelt measurements are reported from 5775 lambs born to Border Leicester × Merino (BLM) and Hyfer (Dorset × Merino composite) ewes joined to Dorset, Suffolk and Hyfer rams in three lamb-production systems at Cowra and Wagga Wagga over 5 years. The production systems involved lambings at different seasons of the year and increasing levels of intensification from autumn annual joining, spring joining with a backup mating for non-pregnant ewes, to an accelerated 8-monthly lambing system. Lambs from BLM ewes were 0.7 kg heavier at birth and grew 3% faster and reached slaughter, at 18 kg carcass weight, 1–2 weeks earlier than did lambs from Hyfer ewes (P < 0.01). The advantage in growth rate of lambs from BLM compared with Hyfer ewes was greater for lambs born in November. These lambs had poorer growing conditions over the summer months, with 22% lower growth rate and taking 5 weeks longer to reach slaughter than did lambs born in March or August. There was no difference between Dorset and Suffolk sire breeds for any lamb growth traits, with lambs from Hyfer sires growing 7% slower. Ram and cryptorchid lambs reached slaughter 1 week earlier than did wethers, with ewes a further 9 days later (P < 0.01). Sex differences were maximised when lamb growth was greatest. There were no differences in carcass fat measurements between ram and cryptorchid lambs, although both were considerably leaner than wethers (2.2–3.0 mm fat at the GR site), which were 1.3–2.1 mm leaner than ewes at 18-kg carcass weight. The range in average growth rate of progeny of the BLM ewes from the 12 different source flocks at Cowra and Wagga Wagga was 10–14% of the mean which was twice the difference in average growth rate of progeny from the BLM and Hyfer dams. There was also significant variation among the BLM source flocks for carcass fat measurements. Lamb progeny from the different sire- and dam-breed combinations had varying levels of heterozygosity. There appears to be little loss of heterosis or hybrid vigour for lamb growth, although the sire breed × dam breed interaction was significant (P < 0.01) for age at slaughter at Wagga Wagga, in which the ranking of the lamb types was consistent with the levels of heterozygosity. The estimates of between-lambing repeatability for the ewes were highest for birthweight (0.35 Cowra and 0.27 Wagga Wagga) and declined at later ages (0.26–0.17), with lower estimates for carcass traits.

Recorded Data

The preweaning growth of the progeny from 2531 first-calf heifers calving on commercial properties in the south-west of Western Australia was studied over 5 years. Animals included the progeny of Angus sires mated to Angus, Angus x Friesian, Simford, Hereford and Beef Shorthorn crossbred heifers; the progeny of Hereford sires mated to Hereford, Hereford x Friesian, and Beef Shorthorn crossbred; and those of Devon crossbred, Simford or Wokalup multibreed heifers mated inter se. Calves were born between mid January and July of each year and date of birth, calving information and calf growth through to weaning at an average age of 230 days were recorded. Data recorded on the calves' dams included regular liveweight and condition score assessment and the date of second calving. Angus-sired calves were lighter at birth than Hereford-sired calves; breed means ranged from 25.1 kg for purebred Angus to 33.2 kg for Wokalup multibreeds, with male calves weighing 1.4 kg more than females at birth. Calf birth weight was positively and linearly related to weight of dam at the beginning of joining. Breed of calf, sex of calf, year of birth, day of the year born, liveweight and liveweight change of the dam at the beginning of rejoining all significantly influenced calf growth, with up to 64% of variation accounted for. At 50 days of age, Devon crossbreds, Simfords and Wokalup multibreeds were significantly heavier than crossbred Hereford or Angus calves, and this trend persisted until weaning. The average growth rate to 200 days of Angus calves was 0.113 kg/day slower, and Hereford calves 0.77 kg/day slower, than the average growth rate of their respective crossbred calves. Heaviest 200-day weights were found in Devon crossbred (235 kg), Simford (221 kg) and Wokalup multibreed (219 kg) calves. A strong seasonal influence on calf growth was detected. Each 1 day increase in calf age in calves born between mid January and June resulted in 0.29 kg extra liveweight at 100 days and 0.68 kg extra liveweight at 200 days of age. Overall, the liveweight of the dam at the beginning of re-joining was positively associated with calf growth, with 0.119 kg of calf liveweight/kg dam liveweight at 100 days and 0.123 kg at 200 days. There was less effect of dam liveweight in Herefords and Hereford x Friesians on calf growth to 200 days, but this relationship was closer in faster growing and later maturing breeds, including Angus x Friesian, Simford, and Wokalup multibreed. The dairy crossbreeds generally lost weight at the beginning of re-joining, resulting in a negative association between this weight change and calf growth to 100 days. No assistance was required in 93% of calvings and the highest incidence of dystocia corresponded with the highest birth weight calves in Wokalup multibreeds. The most common calving difficulty was an apparently slow birth where no assistance was given, resulting in a stillborn calf. Male calves experienced 3 times the level of dystocia recorded for female calves. There was no association detected between dystocia and dam liveweight subsequent to calving. The study highlighted the importance of dam breed, liveweight and condition of the dam and timing of calving as important influences on the growth of progeny reared by first-calf heifers.

An experiment was carried out to find the salinity tolerance capability and growth performance of Climbing Perch, Anabas testudineus (Bloch, 1795). Anabas testudineus commonly cultured fish in Bangladesh was reared in laboratory conditions at different salinities of 0, 3, 6, 9, 12, 15, 18 and 21‰ for 60 days. Hundred per cent survivals were detected at 0, 3, 6 and 9‰ salinity while 100% mortality was recorded at 18 and 21‰ salinity. Various responses to threat and feeding were observed among the fish in different treatments. Lowest feed conversion ratio was found in the control group while the highest was detected at 15‰ salinity. On the other hand, decreasing trend of specific growth and average growth rate were observed in A. testudineus fingerlings from 0 to 15‰ salinity. Significantly higher specific growth rate and average growth rate were detected in A. testudineus fingerlings reared at 0 - 6‰ salinity (p < 0.05). The present study suggests that Climbing Perch fingerlings can be reared at fresh water growth rates in coastal water with salinity up to 6‰.Dhaka Univ. J. Biol. Sci. 25(1): 65-73, 2016

Abstract Continued post-collapse volcanic activity can cause the rise of a new edifice. However, details of such edifice rebirth have not been documented yet. Here, we present 7-decade-long photogrammetric data for Bezymianny volcano, Kamchatka, showing its evolution after the 1956 sector collapse. Edifice rebirth started with two lava domes originating at distinct vents ~400 m apart. After 2 decades, activity became more effusive with vents migrating within ~200 m distance. After 5 decades, the activity focused on a single vent to develop a stratocone with a summit crater. We determine a long-term average growth rate of 26,400 m3/day, allowing us to estimate the regain of the pre-collapse size within the next 15 years. Numerical modeling explains the gradual vents focusing to be associated with loading changes, affecting magma pathways at depth. This work thus sheds light on the complex regrowth process following a sector collapse, with implications for regrowing volcanoes elsewhere.

Annual Average Growth Rate

In his note on my recent two articles in this journal, Professor Addington Coppin states that the results obtained for estimating agricultural contribution to economic growth in various economies are sensitive to employing annual average growth rate data, end-of-period output shares, and geometric “weights” in some of the calculations. He suggests that the results would have been more accurate by employing (1) simple percentage changes in the level variables over the entire period of consideration; (2) beginning-of-period data on output shares; and (3) arithmetic weights. This reply addresses the logic and correctness of the approach undertaken in my research that strengthen the confidence in the results offered in my articles.
