Vigilance behaviour in Alpine ibex (Capra ibex) and Alpine chamois (Rupicapra rupicapra) kids
In prey species, vigilance is an important behavioural trait with regard to antipredator strategies. It has been studied intensely in animals. However, lile is known about vigilance in animal kids. In this study, I investigated the inuence of various environmental and social factors on Alpine ibex (Capra ibex) and Alpine chamois (Rupicapra rupicapra) kid vigilance behaviour. In the Gran Parad...
متن کاملEpizootiologic investigations of selected abortive agents in free-ranging Alpine ibex (Capra ibex ibex) in Switzerland.
In the early 2000s, several colonies of Alpine ibex (Capra ibex ibex) in Switzerland ceased growing or began to decrease. Reproductive problems due to infections with abortive agents might have negatively affected recruitment. We assessed the presence of selected agents of abortion in Alpine ibex by serologic, molecular, and culture techniques and evaluated whether infection with these agents m...
متن کاملA Note on the Convergence of the Homotopy Analysis Method for Nonlinear Age-Structured Population Models
In this paper, a theorem is proved which presents the series solution obtained from the homotopy analysis method is convergent to the exact solution of nonlinear age-structured population models.
متن کاملThe replicator dynamics for age structured populations
1 Abstract In this paper is presented the new modelling framework combining the repli-cator dynamics (which is the standard model of the frequency dependent selection) with the Leslie Matrix model of the age-structured population. Firstly the continuous version of the discrete Leslie Matrix model is derived. It is shown that Euler–Lotka equation is satisfied when new model reaches the steady st...
متن کاملGenerating a Dynamic Synthetic Population – Using an Age-Structured Two-Sex Model for Household Dynamics
Generating a reliable computer-simulated synthetic population is necessary for knowledge processing and decision-making analysis in agent-based systems in order to measure, interpret and describe each target area and the human activity patterns within it. In this paper, both synthetic reconstruction (SR) and combinatorial optimisation (CO) techniques are discussed for generating a reliable synt...
