The thesis includes the results of over ten years' research and observations of lichens on the straw-thatched roofs. The research sites were the villages located inside and on the edge of the vast lowland forests in Poland. The thatched roofs made of straw, which has been laid out for 1–50 years, were examined. Duration of the population process and quantitative changes of pioneering lichens were analysed. The following phases of the initial stage of formation of lichen flora were distinguished and characterized: the phase of occurrence of crustose lichens ('the straw thatch'), the phase of expansion of cup-moss ('the cup-moss thatch') and the phase of a shared domination of lichens and mosses ('the grey-green thatch'). The morphological and ecological features of pioneering lichens were revealed.

This note is a reply to Kim's critique on my paper concerning Simon's city-size distribution model. First, Kim's critique is shown not to be relevant. Second, to make the debate constructive, a possible direction toward a more general city-size distribution model is shown in the context of a Markov population process.

Este artigo teve por base rever os principais resultados de investigações arqueológicas realizadas entre os anos 1990 e 2020 no sítio Pedra do Alexandre, Seridó, Rio Grande do Norte, com pinturas rupestres e sepultamentos humanos. Durante este processo, foram identificados três problemas de pesquisa: caracterização da tradição dos registros rupestres; a geomorfologia e paleoambiente e a formação do depósito arqueológico; as práticas funerárias e as características bioarqueológicas, com ênfase neste artigo. As prerrogativas para o futuro demandam o uso de tecnologia para análises bioquímicas, radiocarbônicas e isotópicas para a interpretação do processo de povoamento regional, como também novos dados sobre dieta, paleopatologia e reconstituição do paleoambiente. THE PEDRA DO ALEXANDRE ARCHAEOLOGICAL SITE, SERIDÓ, RIO GRANDE DO NORTE: Main Results of Studies, Burials and Perspectives for the Future  ABSTRACTThis article is intended to review the main results of archaeological investigations carried out between the 1990s and 2020 at the Pedra do Alexandre site, Seridó, Rio Grande do Norte, with cave paintings and human burials. During this process, three research problems were identified: characterization of the tradition of rock records; geomorphology and paleoenvironment and the formation of the archaeological deposit; funerary practices and bioarchaeological characteristics, with emphasis on this article. The prerogatives for the future demand the use of technology for biochemical, radiocarbon and isotopic analyzes for the interpretation of the regional population process, as well as new data on diet, paleopathology and paleoenvironmental reconstitution.Keywords: Pedra do Alexandre; archaeological research; human burial

A particle travels along the half-line [0,∞) in such a way that it has probability λδu + o(δu) of generating an event in any small element (u,u + δu) of its track. The particle is observed only in the line segment 0 ≦ u ≦ x and successive events occur at X 1, X 2, …, X n (0 ≦ X 1 ≦ X 2 ≦ … ≦ X n ≦ x) where X 1, …,Xn are random variables and the number n of events in [0, x] is also random. The distances constitute a finite univariate population process as defined by Moyal [1], the individuals being the distances Yi with state space [0, x].
