WHEN COMMON BIRDS BECAME RARE: HISTORICAL RECORDS SHED LIGHT ON LONG-TERM RESPONSES OF BIRD COMMUNITIES TO GLOBAL CHANGE IN THE LARGEST WETLAND OF FRANCE.

When Common Birds Became Rare: Historical Records Shed Light on Long-Term Responses of Bird Communities to Global Change in the Largest Wetland of France.

Many species have suffered large population declines due to the anthropogenic influence on ecosystems.Understanding historical population trends is essential for informing best efforts to preserve species.We propose a new method to reconstruct the past structure of Girls Easter Dress a regional species pool, based on historical naturalist literatur

Rat Merkel cells are mechanoreceptors and osmoreceptors.

Merkel cells (MCs) associated with nerve terminals constitute MC-neurite complexes, which are involved in slowly-adapting type I mechanoreception.Although MCs are known to express voltage-gated Ca2+ channels and hypotonic-induced membrane deformation is known to lead to Ca2+ transients, whether MCs initiate mechanotransduction is currently unknown.

Isothermal pumping analysis for high-altitude tethered balloons

High-altitude tethered balloons have potential applications in communications, surveillance, meteorological observations and climate engineering.To maintain balloon buoyancy, power fuel cells and perturb Switchmode atmospheric conditions, fluids could be pumped from ground level to altitude using the tether as a hose.This paper examines the pumping
