Spatial patterns generated by simultaneous cooperation and exploitation favour the evolution of altruism

Journal of Theoretical Biology, 2018
In kin selection theory in the evolution of social behaviours, the relatedness between interacting individuals is influenced by the spatial structure of the population. It is generally considered that in the 'viscous' population competition among individuals tends to suppress the evolution of altruism. We consider that more complex interactions produce

Evolution of Spatial Patterns in Host-Parasitoid Metapopulation

2018
Diverse patterns of species persistence, abundance, and distribution are seen in nature. Ecological interactions, environmental and habitat heterogeneity, demographic and genetic inhomogeneity—are some of the factors that shape population persistence, spatial distribution, and diversity of the species, as well as their life history traits.

Global spatial patterns of infectious diseases and human evolution

2007
Abstract This chapter surveys global spatial patterns of the incidence of infectious diseases and human genetic variation. Contagious diseases are everywhere; zoonotic pathogens are concentrated in the tropics. Thus, populations in the tropics have suffered, and are still suffering, from a greater diversity of pathogens.

Spatial Pattern Evolution and Influencing Factors of Foreign Star-Rated Hotels in Chinese Cities

open access: yes
Spatial distribution is a critical factor influencing the success or failure of hotel management. This study examines the spatial distribution patterns of foreign star-rated hotels in China from 2000 to 2015 based on 27 typical city cases, using global ...

Spatial Pattern Evolution of Coal Consumption at Provincial Level in China

Advanced Materials Research, 2013
Exploratory Spatial Data Analysis was used to analyze the evolvement of spatia1 pattern on coal consumption in China since 2002. General spatial autocorrelation of coal consumption in 31 provinces of China was analyzed by Morans I and Getis-Ord General G.

Emergence and Evolution of Heterogeneous Spatial Patterns [PDF]

open access: possible, 2006
We live in a quite heterogeneous space. There are cities and rural areas, and population density varies a lot across space. People migrate and commute to the places of their work. The goal of this article is to clarify the mechanism of commuting as an equilibrium in heterogeneous space with different technologies.

Spatial and temporal evolution patterns and spatial spillover effects of carbon emissions in China in the context of digital economy

Journal of Environmental Management
Global warming caused by carbon emissions has become a significant concern for countries worldwide. This study thoroughly examines the spatiotemporal patterns and spatial spillover effects of carbon emissions in China. This research employs kernel density estimation, Moran's index, and the standard deviation ellipse model to analyse the spatiotemporal ...
