About 60 species are known to infect and kill pest arthropods and vectors of human diseases. This booklet provides an overview on this interesting and biologically and economically...

This paper derives the conditions under which fitness-reducing alleles can survive in a longrun stationary equilibrium for a trading population, extending the results in Saint-Paul (2002) for arbitrary systems of sexual reproduction

The article presents the features of biology and ecology, the growth and development of various types of Cousinia in various environmental conditions of Uzbekistan.

The rapidly increasing human pressure on the biosphere is pushing biodiversity into the sixth mass extinction event in the history of life on Earth. The organisms being exterminated are integral working parts of our planet's life support system, and their loss is permanent. Like climate change,...

The paper develops a simple economic model of a biological invasion. The natural growth of the invasion is non-convex and the immediate cost of controlling the invasion depends on the level of current control as well as the current size of the invasion. Greater control raises control costs today...

In the face of insufficient progress in conserving and restoring biodiversity, the in situ use of advanced genetic modification, gene drives, and other biotechnologies for conservation purposes are being considered, researched, and developed. This paper introduces the methods, applications,...

The purpose of the paper is to enrich the standard toolbox for measuring diversity in economics. In so doing, we compare the indicators of diversity used by economists with those used by biologists and ecologists. Ecologists and biologists are concerned about biodiversity: The diversity of...
