Data from: Retinal capillary rarefaction in patients with untreated mild-moderate hypertension

Agnes J. Bosch, Joanna M. Harazny, Iris Kistner, Stefanie Friedrich, Joanna Wojtkiewicz & Roland E. Schmieder
Background: Microvascular rarefaction influences peripheral vascular resistance, perfusion and metabolism by affecting blood pressure and flow pattern. In hypertension microvascular rarefaction has been described in experimental animal studies as well as in capillaroscopy of skin and biopsies of muscle tissue in patients. Retinal circulation mirrors cerebral microcirculation and allows non-invasive investigations. We compared capillary rarefaction of retinal vessels in hypertensive versus normotensive subjects. Methods: In this study retinal capillary rarefaction in 70 patients with long...

Data from: Analysis of morphological variability in the clam shrimp Eosestheria middendorfii (Crustacea, Spinicaudata) from the Lower Cretaceous of China, and its implications for spinicaudatan taxonomy

Manja Hethke, Franz T. Fürsich, Jacob D. Morton & Baoyu Jiang
Unresolved taxonomic issues regarding spinicaudatans, clam shrimps that formed the most abundant faunal element in the lacustrine Barremian to Aptian Yixian Formation, have hampered palaeoecological and evolutionary interpretations of this key fossil group. Here, we analyse morphological variability in East Asian clam-shrimp taxa by quantifying: (1) size and shape; and (2) ornamental features (radial lirae distances). Intergeneric variability was examined using 51 specimens of various East Asian Mesozoic taxa, 16 of which were chosen for...

Data from: Harnessing stratigraphic bias at the section scale: conodont diversity in the Homerian (Silurian) of the Midland Platform, England

Emilia Jarochowska, David C. Ray, Philipp Röstel, Graham Worton & Axel Munnecke
Fossil abundance and diversity in geological successions are subject to bias arising from shifting depositional and diagenetic environments, resulting in variable rates of fossil accumulation and preservation. In simulations, this bias can be constrained based on sequence-stratigraphic architecture. Nonetheless, a practical quantitative method of incorporating the contribution of sequence-stratigraphic architecture in community palaeoecology and diversity analyses derived from individual successions is missing. As a model of faunal turnover affected by the stratigraphic bias, we use...

Data from: Measuring β‐diversity by remote sensing: a challenge for biodiversity monitoring

Biodiversity includes multiscalar and multitemporal structures and processes, with different levels of functional organization, from genetic to ecosystemic levels. One of the mostly used methods to infer bio- diversity is based on taxonomic approaches and community ecology theories. However, gathering extensive data in the field is difficult due to logistic problems, especially when aiming at modelling biodiversity changes in space and time, which assumes statistically sound sampling schemes. In this context, airborne or satellite remote...
