The enemy release hypothesis, which posits that exotic species are less regulated by enemies than native species, has been well-supported in terrestrial systems but rarely tested in marine systems. Here, the enemy release hypothesis was tested in a marine system by excluding large enemies (>1.3 cm) in dock fouling communities in Washington, USA. After documenting the distribution and abundance ...

There is an economic natural resource curse as well as a political natural resource curse. The economic literature identifies certain characteristics of countries that are likely to fall victims to the former curse. ent literature on the y to explore the question In this essay we draw on these characteristics, rec political natural resource curse and Cuba’s histor of how likely is Cuba to fall...

Popper conceived an experiment whose analysis led to a result that he deemed absurd. Popper wrote that his reasoning was based on the Copenhagen interpretation and therefore invalidated the latter. Actually, Popper’s argument involves counterfactual reasoning and violates Bohr’s complementarity principle. The absurdity of Popper’s result only confirms Bohr’s approach. I called thee to curse min...

If the value of a commodity is unknown, a prospective buyer must realize that a bid based on an overestimate of its value is likely to be accepted. In this situation, merely finding out that one’s bid is accepted may cause one to reduce the estimate of a commodity’s value, so winning an auction can bring a feeling of regret. Acceptance of a bid is an informative event, and failure to incorporat...

Currently, evidence on the ‘resource curse’ yields a conundrum. While there is much crosssection evidence to support the curse hypothesis, time series analyses using vector autoregressive (VAR) models have found that commodity booms raise the growth of commodity exporters. This paper adopts panel cointegration methodology to explore longer term effects than permitted using VARs. We find strong ...

The topic of human relationships—be they positive and sympathetic, or negative and hostile—receives a great amount of attention in the Qur’ān. Human beings need to be aware of both their friends and their enemies in order to learn how to engage with both groups, how to make additional friends and defend themselves from harm caused by enemies, and, if possible, turn these enemies into friends. T...

Genetic correlations between plant resistances to multiple natural enemies are important because they have the potential to determine the mode of selection that natural enemies impose on a host plant, the structure of herbivore and pathogen communities, and the success of plant breeding for resistance to multiple diseases and pests. We conducted a meta-analysis of 29 published studies of 16 dif...

Dengue is an infection that is carried by Aedes mosquitoes (Diptera: Culicidae) and can cause severe disease in peoples living in tropics. It is capable to cause headaches, pain and rash, and in other harsh types, may cause internal bleeding and then mortality of the patient. Currently, there is no vaccine for the treatment of dengue sickness and the most widely used methods for control of dise...

The strength and prevalence of trophic cascades, defined as positive, indirect effects of natural enemies (predatory and parasitic arthropods) on plants, is highly variable in agroecosystems. This variation may in part be due to the spatial or landscape context in which hese trophic cascades occur. In 2011 and 2012, we conducted a natural enemy exclusion experiment in soybean fields along a gra...
