Isolation of genes involved in the mental dysfunction in these disorders should define loci important in brain formation or function. We have identified a highly conserved locus in the distal part of 11 p 13 that is prominently expressed in fetal brain. Minimal expression is observed in a number of other fetal tissues. The gene maps distal to PAX-6 but proximal to the loci for brain-derived neurotrophic factor (BDNF) and the beta subunit of follicle stimulating hormone (FSHB), within a region previously implicated in the mental retardation component of some WAGR syndrome patients. Within fetal brain, the corresponding transcript is prominent in frontal, motor and primary visual cortex as weil as in the caudate-putamen. The characteristics of this gene, including the striking evolutionary conservation at the locus, suggest that the encoded protein may function in brain development.}, subject = {Biochemie}, language = {en} } @inproceedings{FialaRabensteinMaschwitz1994, author = {Fiala, Brigitte and Rabenstein, R. and Maschwitz, Ulrich}, title = {Ant-attracting plant-structures: Food bodies of SE Asian Vitaceae}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-55177}, year = {1994}, abstract = {No abstract available}, subject = {Pflanzen}, language = {en} } @inproceedings{FialaFederleMaschwitzetal.1994, author = {Fiala, Brigitte and Federle, W. and Maschwitz, U. and Azarae, Idris}, title = {The first myrmecophytic 2-partner-system in the genus Macaranga: The association between Macaranga puncticulata and a Componotus (Colobopsis) in Malaysia}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-55144}, year = {1994}, abstract = {No abstract available}, subject = {Biologie}, language = {en} } @article{BlackenhornPerner1994, author = {Blackenhorn, Wolf U. and Perner, Dirk}, title = {Heritability and repeatability of behavioural attributes affecting foraging success and fitness in water striders}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-52496}, year = {1994}, abstract = {Heritabilities and repeatabilities are presented for various behavioural attributes affecting foraging performance and fitness in Aquarius (Gerris) remigis (Heteroptera: Gerridae) females. These behavioural attributes were patch choice, foraging success, capture accuracy, and measures of mobility, activity, skittishness and aggressiveness. Most heritabilities were not significantly different from zero, which may be related to the low sampIe size. Conclusions as to the potential of direct selection on behaviour in this species were consequently limited. In contrast, with a few exceptions (capture accuracy, foraging success), most repeatabilities were significant and at times high (range=O'22-O'79), indicating consistent, stereotypical individual behaviour. Tbe Iife history or reproductive state of the daughter generation individuals signifieantly affected the magnitude of the repeatabilities as weil as the mean values of many of the variables (notably mobility and aggressiveness), the latter in a manner consistent with field observations. This indicates that the state of the organism affects the general environmental variance, thus contributing to the discrepancies between the repeatabilities and the heritabilities obtained. It is suggested that common physiological proeesses (e.g. hormones) may underlie several of the behavioural attributes examined, resulting in possible pleiotropie effects and eonstraints on selection in a heterogeneous environment. It is further suggested that field studies of selection on behavioural attributes may be a more fruitful approach in this species, whose suitability for genetic analysis is limited.}, subject = {Teichl{\"a}ufer}, language = {en} } @article{MaschwitzFialaLinsenmair1994, author = {Maschwitz, Ulrich and Fiala, Brigitte and Linsenmair, Karl Eduard}, title = {Clerodendrum fistulosum (Verbenanceae), an unspecific myrmecophyte from Borneo with spontaneously opening domatia}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-31013}, year = {1994}, abstract = {Clerodendrumjistulosum Becc. is a true myrmecophyte as it offers nesting space for ants in hollow intemodes.
