1Root and leaf functional trait relations in Poaceae species: implications of differing resource- acquisition strategies显示文摘Aims root systems play an essential role in grassland functioning in both acquisition and storage of resources.Nevertheless,root functional traits have not received as much attention as those measured on above-ground organs,and little is known about their relations.our objec-tives were to test whether morphological and root system traits allowed identification of grass species’functional strategies and to determine whether a relation exists between above-and below-ground traits.Methods Functional traits of root tissues(specific root length,diameter,tissue density and nitrogen concentration),whole root systems(root mass,root length density,root mass percentage below a depth of 20 cm and fine root%)and two major leaf traits(specific leaf area and leaf dry matter content)were determined under field conditions and their rela-tions were analysed in eleven perennial temperate Poaceae species.Important Findings Canonical correspondence analysis along axis 1 revealed a gra-dient of species,from those with deep,dense and coarse root systems with a large root mass to those with shallow root sys-tems,thin roots and high specific root length;this suggests strong correlations among root traits.Correlations between specific root length and specific leaf area reveal two groups of species,which probably indicates different drought-tolerance capacities.root trait syndromes enable ranking grasses along a gradient from conservative-strategy species(from stressful habitats),which display a deep and coarse root system,to acquisitive species(from rich and moist meadows),which display a shallow and thin root system.although both types display similar above-ground strategies,drought-tolerant species have lower specific root lengths than drought-sensitive species,revealing more conservative root strategies.Florian Fort Claire Jouany Pablo Cruz 2013Journal of Plant Ecology2013,6,3:11
2Hypothalamic-pituitary-adrenal axis function during perinatal depression显示文摘Abnormal function of the hypothalamic–pituitary–adrenal(HPA) axis is an important pathological finding in pregnant women exhibiting major depressive disorder. They show high levels of cortisol proinflammatory cytokines, hypothalamic-pituitary peptide hormones and catecholamines, along with low dehydroepiandrosterone levels in plasma. During pregnancy, the TH2 balance together with the immune system and placental factors play crucial roles in the development of the fetal allograft to full term. These factors, when altered, may generate a persistent dysfunction of the HPA axis that may lead to an overt transfer of cortisol and toxicity to the fetus at the expense of reduced activity of placental 11β-hydroxysteroid dehydrogenase type 2. Epigenetic modifications also may contribute to the dysregulation of the HPA axis. Affective disorders in pregnant women should be taken seriously, and therapies focused on preventing the deleterious effects of stressors should be implemented to promote the welfare of both mother and baby.Phillipe Leff Gelman Mónica Flores-Ramos Margarita López-Martínez Carlos Cruz Fuentes Juan Pablo Reyes Grajeda 2015Neuroscience Bulletin2015,31,3:6
