For thousands of years, humans have known the value of honeybees in agriculture. Their pollination services are crucial for the mankind, the Global ecosystem and food production. The recently documented decline of the honeybee colonies in the world is alarming and may threaten the whole living...

Building on the philosophy of Charles Sanders Peirce, recent advances in biosemiotics have resulted into a concise framework for the analysis of signs in living systems. This paper explores the potential for economics and shows how biosemiotics can integrate two different research agendas, each...

Based on economic methodology we model an ecosystem with two species in predator-prey relationship: mice feed on grain and grain feeds on a resource. With optimizing behavior of individual organismus a short-run ecosystem equilibrium is defined and characterized that depends on the farmer's use...

We analyze the effect of environmental uncertainties on optimal fishery management in a bio-economic fishery model. Unlike most of the literature on resource economics, but in line with ecological models, we allow the different biological processes of survival and recruitment to be affected...

Empirical studies of tropical forest hunting have shown the existence of marked spatial gradients of hunting effort, game harvest, and animal abundance, as hunters mostly hunt near villages, roads, and rivers. The mechanisms underlying these patterns have, however, hitherto been poorly known....
