Inferring alternative ecosystem states with field survey data

Methods in Ecology and Evolution, EarlyView.
Abstract Many ecosystems potentially exhibit alternative stable states, where distinct states can coexist under identical environmental conditions. While simulation models have generated key hypotheses in alternative stable states theory, they often rely on scale‐free parameters disconnected from real ecosystems.

Belief merging and revision under social influence: An explanation for the volatility clustering puzzle

A share price in a stock market can be thought of as arising out of an aggregation procedure. The price of a stock aggregates many individual beliefs into a collective one, the collective will of the market, so to speak.

Colony‐level pollen collection reflects visitation of managed bumble bees (Bombus impatiens) in strawberry fields and surrounding landscapes without reducing pollen limitation

Agricultural and Forest Entomology, EarlyView.
We extracted pollen from colony beeswax to quantify season‐long, colony‐level resource use and tested how managed Bombus impatiens visitation and Rosaceae pollen collection relate to landscape context and strawberry pollination. Increased managed bumble bee visitation was not influenced by surrounding landcover, did not reduce pollen limitation and ...

The oscillatory response of the electroretinogram and neuronal adaptation

Acta Ophthalmologica, EarlyView.
Abstract After more than 50 years, there still remains a challenge and an interest to know more as well as extend and deepen our understanding of the small rapid wavelets, the oscillatory potentials (OPs), of the electroretinogram (ERG) and the neuronal adaptation of the retina.

En face localization of retinal telangiectatic capillaries using OCT compared with ICG angiography in chronic vascular macular oedema

Acta Ophthalmologica, EarlyView.
Abstract Purpose Retinal telangiectatic capillaries (TelCaps) are microvascular abnormalities associated with chronic vascular macular oedema and suboptimal response to intravitreal therapy. Targeted laser photocoagulation is beneficial but requires precise localization using indocyanine green angiography (ICG‐A), the reference standard. However, ICG‐A

Reciprocal Tariffs and Systemic Trade Losses: Evidence From Korea, Japan, and the EU

Asia Pacific Viewpoint, EarlyView.
ABSTRACT The resurgence of U.S. protectionism, the proposal of universal reciprocal tariffs targeting major trading partners, poses systemic risks to global trade that existing bilateral analyses have not fully captured. This paper examines the economic consequences of U.S.
