Book ; Online: Koolstofvastlegging in grasvelden

Fuchs, Lennart / van der Schoot, Jan Rinze / Dekkers, Maria-Franca / van Gestel, Stefan

Abstract	Een van de maatregelen om de effecten van klimaatverandering te beperken is de opslag van CO2 in de bodem. In stedelijke gebieden zijn verschillende grasvelden te vinden, zoals sportvelden, parken en bermen. In de PPS Grasvelden, Klimaat & Biodiversiteit is onderzocht hoeveel koolstof er is vastgelegd. De hoeveelheid koolstof is afhankelijk van veel verschillende factoren, waarvan een deel niet eenvoudig te beïnvloeden zijn. In veldonderzoek is in de laag van 0-20 cm gemiddeld 50 tot 80 ton C/ha aanwezig. Omdat niet bekend was hoeveel koolstof aanwezig was voor de aanleg, kunnen geen uitspraken worden gedaan over de hoeveel koolstof die door het gras zelf is vastgelegd. De resultaten gaven aan dat bij grasveldbeheer ten behoeve van (extra) koolstofvastlegging, geen onderscheid gemaakt hoeft te worden tussen de verschillende soorten grassoorten. Rietzwenkgras vormt hierop een mogelijke uitzondering. Bij grasonderhoud kan wel rekening worden gehouden met de maaifrequentie en maaihoogte. Deze factoren kunnen namelijk invloed hebben op de koolstofopslag onder grasvelden.

Abstract	Soil quality and thus sustainable soil management has become increasingly important in modern agricultural systems. Since 2011 the experiment Soil quality on sandy soil (Bodemkwaliteit op Zand) combines noninversion tillage with conventional ploughing to research the effects on ecosystem services. The effect of non-inversion tillage on the crop yields and quality and soil quality are small. Weed densities increase under non-inversion tillage, while nitrogen losses decrease. Overall, non-inversion tillage is well applicable in an arable system on a sandy soil, when weeds can be controlled.

Abstract	For centuries, scientists are intrigued by the differences in personality between individuals. As early as in the ancient Greek civilization, people tried to formulate theories to systematize this diversity. With the increased interest in behavior genetics, personality was also considered a challenging phenotype. From the early start, studies suggested a heritable component in personality. After the successes of molecular genetic studies in unraveling the genetic basis of (mostly) monogenic diseases, the focus shifted towards complex traits, including psychiatric disorders. It was observed in several studies that personality measures differed between patients with psychiatric disorders and healthy controls. Therefore, normal personality was considered a viable endophenotype in the search for genes involved in psychiatric disorders such as affective disorders, ADHD and substance dependence. Genes that were to be found in studies on personality could be candidate genes for particular psychiatric disorders. In the course of time, however the study of genes for personality turned out to be at least as hard as the search for genes involved in other complex disorders. In this review, past studies, present problems and future directions concerning the study of personality genetics are discussed.

Abstract	Intrauterine factors important for cognitive development, such as birth weight, chorionicity and umbilical cord characteristics were investigated. A total of 663 twin pairs completed the Wechsler Intelligence Scale for Children-Revised and scores were available for Performance, Verbal and Total Intelligence Quotient (IQ). The intrauterine factors examined were birth weight, placental weight and morphology, cord knots, cord length and cord insertion. IQ scores for the varying levels of the intrauterine markers adjusting for gender and gestational age were calculated. The heritability of IQ and the association between IQ and intrauterine environment were examined. Twins with lower birth weight and cord knots had lower IQ scores. The aetiology of IQ is largely distinct from that of birth weight and cord knots, and non-shared environment may influence the observed relationships.

Article: A prospective twin study of birth weight discordance and child problem behavior.

Abstract	Background: We investigated whether low birth weight constitutes a causal risk factor for child problem behavior, using a variation of the co-twin control method. Methods: In a representative sample of 745 twin pairs (monozygotic: 324 pairs), birth weight was recorded at birth and child problem behavior at mean age 10 years was measured with the Child Behaviour Checklist (CBCL). Results: Lower birth weight was a continuous risk factor for later child problem behavior (adjusted regression coefficient over units of 500 g: beta = -.15, p =.046), and greater levels of within-pair CBCL discordance did not result in a reduced effect size. Greater within-pair birth weight discordance was associated with greater within-pair CBCL score discordance (beta =.35, p <.001). This latter effect was similar in monozygotic (beta =.34, p =.005) and dizygotic twins (beta =.37, p =.003). Conclusions: The fact that (1) the effect size of the association between low birth weight and child problem behavior was not reduced in pairs with greater levels of CBCL discordance, and (2) similar effect sizes were found in monozygotic and dizygotic twins for the within-pair association between birth weight discordance and CBCL score discordance, suggests that the observed relationship between low birth weight and child problem behavior is not due to a shared environmental or genetic variable that influences both characteristics. Lower birth weight is a causal risk factor for child problem behavior, the effects of which may well extend into adulthood.

Abstract	The aim of this study was to validate a zygosity questionnaire that can be administered over the telephone. Mothers of same-sexed twins of known zygosity and chronicity between 2 and 31 years of age were interviewed on a nine-item questionnaire. From the answers one unweighted and four weighted indices were computed. As single questions, the mother's opinion and the "two peas in a pod" question differentiated best between monozygotic and dizygotic twins. One independent well-trained observer assessed the zygosity based on the questionnaire and made the correct diagnosis in 96% of the cases. A weighted index of eight similarity questions yielded an accuracy of 98%. This study shows that the zygosity of same-sexed twins more than 2 years old and without gross physical malformation can reliably be determined by a telephone questionnaire with a high accuracy.

Abstract	Background: Twin studies suggest that environmental effects on the development of child psychopathology largely involve nonshared environmental processes. However, the influence of the nonshared environment may have been overestimated, as the relationship between environment and behaviour may be genetically mediated. A direct measure of the nonshared environment (using the Sibling Inventory of Differential Experience - SIDE) was investigated in relation to child psychopathology, and tested for possible genetic mediation. Method: Parent-rated versions of the Child Behaviour Checklist (CBCL) and the SIDE were collected in 760 twin pairs aged 6-17 years. Multilevel regression analysis was used to assess the influence of SIDE scores on CBCL total problem scores, internalising symptoms, externalising symptoms and depressive symptom scores. Genetic mediation was assessed by examining interaction with zygosity in the association between SIDE scores and differences in CBCL scores (absence of interaction indicating no genetic mediation). Results: The results revealed significant associations between SIDE dimensions on the one hand, and degree of internalising, externalising, depression and total symptom scores on the other. However, the effects were non-linear, and especially apparent for the extremes of differential environmental experience within twin pairs. Overall, there was no strong evidence for genetic mediation of associations between nonshared environment and symptoms. Conclusions: Direct, genetically unconfounded but skewed relationships may exist between nonshared environment on the one hand and behavioural differences on the other, although longitudinal data are necessary to determine the direction of effects.

Abstract	Background: The authors present a patient and describe other cases from the literature which demonstrate that prolonged use of nasogastric tubes can result in life-threatening aortoesophageal fistula formation in patients with a double aortic arch. Conclusion: Aortoesophageal fistula (AEF) is an abnormal communication between the esophagus and the aorta. It can cause massive gastrointestinal hemorrhage. We present an infant with an operatively corrected double aortic arch, who developed this complication after prolonged nasogastric intubation.
