SCALE DEPENDENCE OF LANDSCAPE-STRUCTURE-BASED ESTIMATION OF ABUNDANCE OF EURASIAN SKYLARK (ALAUDA ARVENSIS)

The habitat and occurrence of farmland birds are strongly determined by the agricultural-landscape structure.Changes in land cover composition and configuration are one of the main causes of the significant decline in abundance of the Eurasian skylark (Alauda arvensis) in recent decades.This farmland-bird species is common in agricultural areas of

Tumor-derived exosomes are considered as a key biomarker in the field of liquid biopsy.However, conventional separation techniques such as ultracentrifugation, co-precipitation and column chromatography cannot isolate samples with high throughput, while traditional immunomagnetic separation techniques, due to steric effect of magnetic beads, reduci
