Ancient Burial Mounds Provide Safe Havens for Grassland Specialist Plants in Transformed Landscapes—A Trait-Based Analysis

چکیده
Due to the intensified land use in transformed landscapes, grassland biodiversity is often restricted habitat fragments inadequate for arable or urban development. In continental parts of Eurasia, ~600,000 ancient burial mounds (called “kurgans”) built by nomadic tribes steppes are amongst most widespread landmarks providing refuge dry species. our study using plant functional groups and traits, we aimed at gaining insight into ecological evolutionary processes shaping structure composition assemblages specialist species on kurgans embedded agricultural landscapes East-Hungary. As a comparison, also studied roadside verges pristine extensive grasslands same region. We found that despite their small size, due lack human disturbances high microhabitat diversity can maintain richness percentage cover specialists, especially when compared verges. revealed plants characterized traits typical terrestrial islands such as self-compatibility, large seed mass tall stature. Kurgans were higher (both level single multi-trait based dispersion) which probably environmental heterogeneity homogeneous environment

متن کاملDating of Prehistoric Burial Mounds by 14c Analysis of Soil Organic Matter Fractions
Dating of prehistoric anthropogenic earthworks requires either excavation for archaeological artifacts or macroscopic organic matter suitable for 14C analysis. Yet, the former, in many cases, is undesirable and the latter is difficult to obtain. Here we present a soil science procedure, which has the potential to overcome these problems. It includes careful sampling of buried former soil surfac...
متن کاملRetinal drusen: harbingers of age, safe havens for trouble.
Drusen are small focal extracellular deposits underneath the retina, visible ophthalmoscopically as yellow dots. The more hard drusen there are, the greater the risk of developing soft drusen and retinal pigmentary changes, which in turn increase the risk of developing advanced age-related macular degeneration. Much remains to be discovered about drusen. For the patient with drusen, basic advic...

MOTIVATION The data that put the 'evidence' into 'evidence-based medicine' are central to developments in public health, primary and hospital care. A fundamental challenge is to site such data in repositories that can easily be accessed under appropriate technical and governance controls which are effectively audited and are viewed as trustworthy by diverse stakeholders. This demands socio-tech...
