Behavioral and Historical Processes Jointly Maintain Genetic Connectivity in Fragmented Chinese Water Deer Populations. [PDF]

Ecol Evol
We challenge a major paradigm in mammalian ecology by demonstrating female‐biased dispersal in an artiodactyl, the endangered Chinese water deer. This key behavioral mechanism drives high gene flow across a fragmented landscape, effectively creating a genetic rescue effect that maintains population connectivity and counters inbreeding. ABSTRACT Habitat

Genesis and microscopic characteristics of tight reservoirs in the Fengcheng Formation, at the southern margin of the Mahu Sag

Energy Geoscience, 2023
The tight reservoirs of the Fengcheng Formation at the southern margin of the Mahu Sag have strong heterogeneity due to the diversity in their pore types, sizes, and structures. The microscopic characteristics of tight reservoirs and the mechanisms that generate them are of significance in identifying the distribution of high-quality reservoirs and in ...
