Tyrosinemia type II (Richner-Hanhart syndrome) is a rare autosomal recessive disease with deficiency of tyrosine aminotransferase and subsequently increasing level of serum tyrosine. We report the case of a 2-year-old girl who was referred due to bilateral corneal lesions. Slit-lamp examination showed small granular white deposits arranged in a dendritic pattern in the superficial central corne...

C ross-fostering techniques in which infants are taken from their genetic parents and reared by unrelated foster parents have been widely used in behavioural research to investigate several developmental questions. Here we address some of the central issues involved in using cross-fostering to study kin recognition where it has been applied frequently. We do so by first outlining general princi...

Future plans of the California Ins titute of T echno logy Libraries (Brudwig, 1984) include an online analytic catalog of books, serials, journals, a nd technical reports . In an attempt to avoid the observation of Mandel a nd Herschman (1983) that " new technologies are often adapted to traditiona l uses without exploiting added capabilities" (p . 148), a number of innovative cataloging approa...

In birds, the quality of rearing conditions is a major determinant of nestling body condition, nestling survival and recruitment probability (Martin 1987). When food becomes short, sibling competition increases (Mock & Parker 1997), growth is depressed (Smith et al. 1989), and chicks are more vulnerable to environmental stress factors (Hoffmann & Merila 1999). Although the effect of rearing con...

In species with biparental care, a female gains fitness benefits from the joint reproductive investment of herself and her partner, but pays only the costs of her own care. Selection thus favours mechanisms that allow females to elicit a higher paternal investment from their partners. In oviparous species, the allocation of maternal yolk androgens to the eggs might represent such a female adapt...

—We tested for the presence of compensatory growth (i.e. faster age-specific growth) following ephemeral periods of food restriction in altricial nestlings using the House Sparrow (Passer domesticus) as a model species. To simulate periods of poor food conditions, we raised nestlings in captivity, fed them a synthetic diet, and held them at constant body mass for 48 h beginning on either day 3 ...

Four lines of evidence indicate that evening bats, Nycticeius humeralis, at nursery colonies in northern Missouri transfer information by following each other to feeding and roosting sites . (1) Daily estimates of insect density from five automated suction traps showed that common prey in evening bat faecal samples, small beetles and flies, occur in rich patches that persist for several days . ...
