This research work deals with mathematical modeling in complex biological systems in which several types of individuals coexist in various populations. Migratory phenomena among the populations are allowed. We propose a class of mathematical models to describe the demographic dynamics of these type of complex systems. The probability model is defined through a sequence of random matrices in which rows and columns represent the various populations and the several types of individuals, respectively. We prove that this stochastic sequence can be studied under the general setting provided by the multitype branching process theory. Probabilistic properties and limiting results are then established. As application, we present an illustrative example about the population dynamics of biological systems formed by long-lived raptor colonies.

The Southeastern Spanish Region of Guadix is a mainly agrarian territory located in the Granada province, which is in demographic decline and has low economic dynamism. Reversing such a difficult socioeconomic situation requires the implementation of policies capable of promoting demographic revitalization and fruitfully exploiting potential for sustainable development in the zone. Such policies must be based on an appropriate diagnosis of the existing problems. In order to provide elements to make said diagnosis, this research combines the use of quantitative and qualitative methods. Quantitatively, the evolution of demographic dynamics in the region have been analyzed, as well as its levels of occupation, education, its economic situation, or its environmental conditions. In this regard, correlation analysis, factorial analysis, and clustering have been completed with the aim of revealing internal territorial imbalances. A series of qualitative interviews with key actors has also been conducted. Finally, given the little success of development programs applied to date, among other things, it is concluded that a greater involvement of local actors in said programs is needed. Thus, these actors have to be involved in development policies, which in turn must take into account the socioeconomic, cultural, environmental, and geological resources available in the area.

Demographic crisis remains one of the main challenges to socio-economic development of Russia. The COVID–19 pandemic has aggravated preconditions for a possible recovery from depopulation. The present article substantiates the need to develop and approve the RF social doctrine upon completion of national projects in 2018–2024. The authors suggest their own approach to overcoming the socio-demographic crisis with regard to the long-term demographic dynamics in Russia. Various scenarios of the “post-coronavirus” future of both specific countries and the world as a whole are proposed.

Metropolitan growth in Europe has resulted in drastic changes of urban forms, socio-spatial structures and land-use patterns due to sequential processes of urbanization, suburbanization and re-urbanization. To assess latent shifts from mono-centric models towards more disarticulated and decentralized settlement configurations, the present study evaluates spatio-temporal patterns of growth between the 1920s and the 2010s in three Mediterranean cities with different structure and functions (Barcelona: compact and moderately polycentric; Rome: dispersed, medium-density; Athens: mono-centric, hyper-compact). To identify and characterize long-term urban transformations, an original approach was illustrated in this study, based on a multivariate analysis of 13 indicators resulting from descriptive statistics and linear regression modeling the relationship between population density and distance from inner cities. The empirical results of this study indicate that Barcelona, Rome and Athens have experienced different urbanization cycles, characterized by a (more or less) concentrated distribution of population along urban gradients. Despite similarities in demographic dynamics and planning practices, these processes have determined (i) a mostly centralized growth in Barcelona, (ii) a relatively dispersed and discontinuous spatial structure in Rome, and (iii) a steep decline of population density with the distance from downtown Athens. Compact urban expansion, population decline and urban de-concentration were finally assessed using the analytical approach proposed in this study.
