Genetic Differentiation of Reed Canarygrass ( L.) within Eastern Europe and Eurasia.

Worldwide molecular research of economically important (Poaceae) is mainly focused on the invasions of this species from Europe to North America. Until the present study, the genetic diversity of the had not been studied across the Baltic countries. The objective of this research is to evaluate the diversity of Lithuanian populations of at simple sequence repeat (SSR) loci comparatively among populations of the Baltic countries, Luxembourg, and the Russian Far East (Eurasian), evaluating differentiation between Lithuanian populations and ornamental accessions, and relating these with environmental features.

Ionomic Parameters of Populations of Common Juniper ( L.) Depending on the Habitat Type.

For the study of the ionomic parameters of needles, fourteen sites covering most of the territory of Lithuania and belonging to distinct habitats (coastal brown dunes covered with natural Scots pine forests (G), scrubs (F), transition mires and quaking bogs (D), subcontinental moss Scots pine forests (G), and xero-thermophile fringes) were selected. Concentrations of macro-, micro-, and non-essential elements were analyzed in current-year needles, sampled in September. According to the concentrations of elements in needles, the differences between the most contrasting populations were as follows: up to 2-fold for Mg, N, K, Ca, and Zn; 2- to 7-fold for P, Na, Fe, Cu, Al, Cr, Ni, and Pb; and 26- to 31-fold for Mn and Cd.

Long-Term Shape, Curvature, and Depth Changes of the Lamina Cribrosa after Trabeculectomy.

Purpose: To evaluate changes in lamina cribrosa (LC) shape, curvature, and depth after trabeculectomy.

Design: Prospective, observational case series.

Participants: A total of 112 patients (118 eyes) with open- or closed-angle glaucoma undergoing trabeculectomy.

The propensity of voles and mice to transmit Borrelia burgdorferi sensu lato infection to feeding ticks.

Lyme borreliosis (LB) caused by the spirochete Borrelia burgdorferi sensu lato is the most common tick-borne zoonosis in the Northern Hemisphere. B. burgdorferi s.
