The ecology, geopolitics, and economics of managing Lymantria dispar in the United States

Critical patch size generated by Allee effect in gypsy moth, Lymantria dispar (L.)

Allee effects are important dynamical mechanisms in small-density populations in which per capita population growth rate increases with density. When positive density dependence is sufficiently severe (a 'strong' Allee effect), a critical density arises below which populations do not persist. For spatially distributed populations subject to dispersal, theory predicts that the occupied area also...

چالش ظهور چین و هژمونی آمریکا در پرتو توافق تجارت آزاد فراپاسیفیک

Beyond its dynamic economic effects, TPP also has powerful geopolitical implications. Centerpieces of United States policy toward Asia—especially East and Southeast Asia—during the Obama presidency have included the “pivot” or “rebalancing” on the security side and seeking Trans-Pacific Partnership as a massive trade agreement on the economic side, from the start, this particular trade pact has...

Geopolitics and Environmental Issues in the Caspian Sea

Nowadays, a noticeable part of the relations among the states turn around the environment protection. Therefore, the right for ever-creasing use of the existing resources of this inland sea cannot be exclusive to any Caspian State and the aftermath involves all countries of this basin. In this respect, agreement on political border and boundaries with the Caspian Sea?s ecosystem is a difficul...

Stock Market Interactions between the BRICS and the United States: Evidence from Asymmetric Granger Causality Tests in the Frequency Domain

The interaction of BRICS stock markets with the United States is studied using an asymmetric Granger causality test based on the frequency domain. This type of analysis allows for both positive and negative shocks over different horizons. There is a clear bivariate causality that runs both ways between the United States stock market and the respective BRICS markets. In addition, both negative a...
