The Rice Genetics Collection of past symposia and other selected literature contains nearly 4,400 pages of searchable information on rice genetics and cytogenetics published by the IRRI and its partners since 1964. In addition to the five genetics symposia held at 5-year intervals since 1985, the collection contains classic publications that kicked off significant reporting on these subjects in the early 1960s. This collection is a comprehensive and historical documentation on the subject of rice genetics, spanning 45 years of research and scholarly work. Published in 1995, Rice Genetics III contains 138 chapters from various contributors on topics dealing with rice genetic research, including varietal differentiation and evolution; genetics of morphological and physiological traits and disease resistance; cytogenetics; tissue and cell culture; molecular mapping of genes; map-based gene cloning; molecular genetics of cytoplasmic male sterility; transformation; gene isolation, characterization, and expression; genetic diversity in pathogen populations; and rice research priorities.

Bank voles (Clethrionomys glareolus) from three age groups were transferred from conditions in which stereotypic behaviour reliably developed to conditions in which stereotypies rarely developed, to test if environmentally induced stereotypies become independent of their causal factors. Forty-eight voles were used, aged 2 months (Young: n = 18); 6 months (Mid: n = 14); and 14 months (Old; n = 16) at the start of the experiment. All had been bred and housed in conventional laboratory cages, in which roughly half of each age group had developed locomotor stereotypies. Half of the voles were housed in a small cage with no vegetation (barren) and half the voles in a larger cage, containing hay and twigs (enriched). After 60 days, the voles were swapped from one treatment cage to the other. Their behaviour was recorded on three occasions in each cage (after 5 days, 30 days and 55 days) on video for 30 min following an unfamiliar stimulus (ball point pen rattled along roof of cage). Voles usually ran or dug in the barren cage, and remained motionless in the enriched cage, immediately following the rattle. There was no evidence of habituation to the rattle. Eight Young, six Mid and 12 Old voles performed stereotypies in the barren cage and three Mid and ten Old voles also performed stereotypies in the enriched cage. No Young voles performed stereotypic behaviour in the enriched cage, so stereotypies were harder to disrupt through environmental enrichment in older voles. Voles that performed stereotypies had a shorter latency to move and spent less time inactive than voles that did not perform stereotypies, in all age groups and both environments, except for Young voles in the enriched cage. These moved later and spent more time inactive in the enriched cage if they had been found to stereotype in the barren cage. This suggests that young stereotyping voles are more responsive to aversive stimuli than non-stereotyping voles, but that their specific behavioural response t
