Drivers of dune formation control ecosystem function and response to disturbance in a barrier island system.

Barrier islands are landscape features that protect coastlines by reducing wave energy and erosion. Quantifying vegetation-topographic interactions between adjacent habitats are essential for predicting long-term island response and resilience to sea-level rise and disturbance. To understand the effects of dune dynamics on adjacent interior island ecosystem processes, we quantified how sediment availability and previous disturbance regime interact with vegetation to influence dune building and ease of seawater and sediment movement into the island interior on two US mid-Atlantic coast barrier islands.

Tick-borne encephalitis virus foci in Slovakia.

Tick-borne encephalitis (TBE) virus as a typical arbovirus relies on two types of hosts for its survival: ticks act both as virus vectors and reservoir hosts, and vertebrates amplify the virus infection by acting as a source of infection for feeding ticks. Longitudinal monitoring of TBE virus in ticks and vertebrate hosts including humans over a period of 40 years resulted in the identification of the areas of Slovakia where TBE virus is endemic. These are concentrated to the western, southern, and eastern parts of the country.
