The complete nucleotide sequence of the mitochondrial genome of the Oriental white stork, Ciconia boyciana, has been determined from captive storks by a novel method incorporating Long PCR and shotgun sequencing. 13 protein-coding genes, two ribosomal RNA genes and 22 transfer RNA genes were identified as in other vertebrate mitochondrial genomes. The position and direction of the NADH6 and tRNA-Glu genes were the same as previously reported for avian mitochondrial genomes. A 71 bp direct repeat and long CAAA repeat sequences were found at the 3' end of the D-loop region, together with SCB-1, SCB-2, SCB-3, and three TAS sequences. Direct sequencing of the PCR fragments in the D-loop region in 26 captive Oriental white storks originating from Japan, China, and Russia revealed nucleotide differences at 18 sites along 1,248 bp, and a total of nine haplotypes have been identified. It was found that one pair of individuals in the Japanese captive breeding program were of the same haplotype, suggesting that they were caught from the same nest. The pair has since been dissolved in consideration of the possibility of inbreeding depression.

On February 10, 2008, a newborn male spectral tarsier (Tarsius tarsier) was found on the floor of the indoor exhibit room in the Small Mammal House of the Ueno Zoological Gardens. The dam showed no signs of providing maternal care and therefore we decided to hand-raise the infant. Its birth weight was 18.7 g. We placed the dam and infant in an incubator and gave 12.5-25% formula (for kittens), until the 145th day after birth. We limited the volume of formula intake to avoid excessive intake and to prevent diarrhea. For nutrition enrichment, we added a chicken liver homogenate to the formula 1-3 times per day. The infant was given a sunbath for 10 min on the 28th day. He showed no serious decline in health, except for diarrhea that occurred during the first few days after birth. He ate a small cricket for the first time on the 50th day and easily caught mealworms on his own on the 105th day. Gradual changes in feeding times, formula concentration, and the nutritionally enriched formula were essential for successfully hand-raising the tarsier.
