BIOGEOGRAPHIC DISTRIBUTION OF AUTOTROPHIC BACTERIA WAS MORE AFFECTED BY PRECIPITATION THAN BY SOIL PROPERTIES IN AN ARID AREA

Biogeographic distribution of autotrophic bacteria was more affected by precipitation than by soil properties in an arid area

IntroductionAutotrophic bacteria play an important role in carbon dioxide fixation and are widespread in terrestrial ecosystems.However, the biogeographic patterns of autotrophic bacteria and the driving factors still remain poorly understood.MethodsHerein, we conducted a 391-km north to south transect (mean annual precipitation <600 mm) survey

Research and Simulation on the Development of a Hydraulic Prop Support System of Powered Roof Support to Increase Work Safety

The underground mining environment is currently based on technology that uses mainly analogue sensors in machine and equipment control systems.The primary machine performing the most important functions in a mining system is the powered roof support.In order for it to work properly, it is important that it achieves the required power.To ensure this

And yet, migration, population growth or mortality are not balanced among Cantabrian brown bear subpopulations. Reply to Blanco et al (2020).

In a recent paper, we presented new evidence and provided new insights on the status of Cantabrian brown bear subpopulations, relevant for this species conservation.Namely, we revealed the likely phylogeographic relation between eastern Cantabrian subpopulation and the historical Pyrenean population.We have also detected an asymmetric flow of allel
