Isolation-by-distance and outbreeding depression are sufficient to drive parapatric speciation in the absence of environmental influences.

A commonly held view in evolutionary biology is that speciation (the emergence of genetically distinct gator mini bone and reproductively incompatible subpopulations) is driven by external environmental constraints, such as localized barriers to dispersal or habitat-based variation in selection pressures.We have developed a spatially explicit model

Measurement and modeling of excess pore-water pressure in warm saturated frozen soil based on dynamic loading effect

Measuring pore-water pressure (PWP) in frozen soils poses significant challenges in geotechnical testing experiments, and understanding PWP is crucial for unraveling the mechanism of frost heave generation in cold regions.This paper aims to clarify the development pattern of PWP in frozen soil through laboratory tests, specifically focusing on exce

Cliffs support lichen communities unique from nearby forests

Cliffs support rare, endemic, and glacial relict vegetation that may differ from vegetation in surrounding forests.Yet, cliffs are difficult to sample, and rock-dwelling lichens can be challenging to identify; therefore, cliff lichens are often excluded from biodiversity studies.This omission creates fundamental gaps in our understanding of cliff l
