In this study, we show that moonmilk subaerial speleothems in Altamira Cave (Spain) consist of a network of fiber calcite
crystals and active microbial structures. In Altamira moonmilks, the study of the typology and distribution of fiber crystals,
extracellular polymeric substances, and microorganisms allowed us to define the initial stages of fiber crystal formation
in recent samples as well as the variations in the microstructural arrangement in more evolved stages. Thus, we have been
able to show the existence of a relationship among the different types of fiber crystals and their origins. This allowed us
to outline a model that illustrates the different stages of formation of the moonmilk, developed on different substrata, concluding
that microbes influence physicochemical precipitation, resulting in a variety of fiber crystal morphologies and sizes. 相似文献

Altamira Cave contains valuable paleolithic paintings dating back to 15,000 years. The conservation of these unique paintings
is attracting increasing interest, and so, understanding microbial proliferation in Altamira Cave represents a prioritary
objective. Here, we show for the first time that members of the Crenarchaeota were metabolically active components of developing
microbial communities. RNA was extracted directly from the studied environment, and a number of 16S rRNA gene sequences belonging
to the low-temperature Crenarchaeota were detected. Although low-temperature Crenarchaeota detected in a variety of ecosystems
by using molecular techniques remain uncultured, this RNA-based study confirms an active participation of the Crenarchaeota
in cave biogeochemical cycles. 相似文献

We analyze a mathematical model of the epizootic of Hantavirus in mice populations, including the effect of species that compete with the host. We show that the existence of the second species has an important consequence for the prevalence of the infectious agent in the host. When the two mice species survive in the ecosystem, the competitive pressure of the second species may lead to reduction or complete elimination of the prevalence of infection. The transition between the disappearance of the infection and its presence occurs at a critical value of the competitor's population, resembling a second-order phase transition in a statistical system. The results provide a rigorous framework for the study of the impact of biodiversity in the propagation of infectious diseases, and further lends itself to future experimental verification. 相似文献
