Pomacea canaliculata (Ampullariidae) has extensively invaded most Asian constructed wetlands and its massive herbivory of macrophytes has become a major cause of ecosystem dysfunctioning of these restored habitats. We conducted non-choice laboratory feeding experiments of P. canaliculata using five common macrophyte species in constructed wetlands including Ipomoea aquatica, Commelina communis,...

I present a general equilibrium model of banking in which financial crises can be due to panics (i.e., coordination failures that give rise to multiple equilibria) or fundamentals. Crises are systemic, in the sense that many banks are insolvent and subject to runs. A financial crisis is also characterized by a flight to safety-liquidity, and by sales of assets by banks at a depressed price, tha...

The regenerative capacity of most tissues declines dramatically after embryonic development and during post-natal life. The underlying mechanisms of this phenomenon are incompletely understood. In a recent issue of Cell, Shyh-Chang and colleagues provide experimental evidence that Lin28 prolongs youthful regenerative capacity by increasing oxidative glucose metabolism (Shyh-Chang et al, 2013).

BACKGROUND Polypoidal choroidal vasculopathy (PCV) has been described since the 1980s with great variations in patient data in different countries. We report the first case series in the Taiwanese population. METHODS We reviewed the medical records of all patients diagnosed with PCV between January 2000 and October 2001 at the retina clinics of Chang Gung Memorial Hospital. RESULTS Eight pa...

Introduced accidentally from South America, deeproot sedge is rapidly expanding in a variety of habitats throughout the southeastern United States. Of particular concern is its rapid expansion, naturalization, and formation of monocultures in Texas coastal prairie, one of the most imperiled temperate ecoregions in North America. The objective of this research was to examine how deeproot sedge r...
