In other niches, such as strict blood feeding, diversification has been severely constrained. Symbioses therefore appear to solve widespread nutrient deficiencies for insects, but the consequences for insect diversification depend on the feeding niche that is invaded....
Diversity is a fundamental, yet threatened, property of ecological systems. The idea that diversity can itself favour diversification, in an autocatalytic process, is very appealing but remains controversial. Here, we study a generalized model of ecologi
Linear classification of EU member states in terms of sustainable development level was carried out on the basis of standard and non-standard methods. Moreover convergence of the classifications was examined. Ward's method and the PAM method were used to group EU member states in terms of ...
Z(λ). In the current setup, in which the constraint space is a Cartesian product of intervals, that is, Ω=∏𝑑𝑖=1[𝑎𝑖,𝑏𝑖],Ω=∏i=1d[ai,bi], the choice of reference measure is very simple: just set 𝑑𝑄(𝜉)=∏𝑗=1𝑑(𝜖𝑎𝑗(𝑑𝜉𝑗)+𝜖𝑏...
One way to balance risk and reward in your investment portfolio is to diversify your assets. This strategy has many different ways of combining assets, but at its root is the simple idea of spreading your portfolio across several asset classes. Diversification can help mitigate the risk and vola...

Insects contain more than half of all living species, but the causes of their remarkable diversity remain poorly understood. Many authors have suggested that herbivory has accelerated diversification in many insect clades. However, others have questioned
