A Five-Species Jungle Game

A Five-Species Jungle Game

In this paper, we investigate the five-species Jungle game in the framework of evolutionary game theory. We address the coexistence and biodiversity of the system using mean-field theory and Monte Carlo simulations. Then, we find that the inhibition from the bottom-level species to the top-level species can be critical factors that affect biodiversity, no matter how it is distributed, whether h...

Diverging fluctuations in a spatial five-species cyclic dominance game.

A five-species predator-prey model is studied on a square lattice where each species has two prey and two predators on the analogy to the rock-paper-scissors-lizard-Spock game. The evolution of the spatial distribution of species is governed by site exchange and invasion between the neighboring predator-prey pairs, where the cyclic symmetry can be characterized by two different invasion rates. ...

A serological survey of brucellosis in wild ungulate species from five game parks in Zimbabwe.

A retrospective serosurvey was carried out between 2009 and 2012 to detect antibodies to Brucella spp. in free-ranging African wildlife ungulates from five selected game parks in Zimbabwe. Samples were drawn from wildlife-livestock interface and non-interface areas in Zimbabwe. A total of 270 serum samples from four different species, namely African buffalo (Syncerus caffer) (n =106), impala (A...

Twelve scientists from Indonesia, Australia and the US recently returned from a two-week trek through the Foja Mountains in the Indonesian west of New Guinea. Their finds have yet to be evaluated and officially classified by experts around the world, but a preliminary count of new species includes one bird, four butterflies, five palms, one flower, four or five mammals, and 20 frogs — close to ...
