TL;DR
These results demonstrate that H. occipitalis remains genetically cohesive at regional scales, yet locally vulnerable to habitat fragmentation, urbanization, and exploitation, and highlight the importance of maintaining breeding habitat connectivity and regulating harvest in rapidly developing landscapes to preserve genetic diversity in widespread amphibians.
The findings reveal pronounced mitochondrial population structure in G. guttulatus and suggest that geographic distance is more closely associated with population genetic differentiation than contemporary drainage-basin or major-river-system boundaries.
The results indicate shallow genetic structure and incomplete spatial differentiation across the species range, highlighting the importance of preserving remnant restinga habitats and maintaining landscape connectivity to safeguard genetic diversity in A. robusta and other habitat-specialist ants.
Mammillaria parkinsonii and M. perbella are species endemic to the Queretano–Hidalguense Desert (QHD), a potential globose cacti Pleistocene refuge. We tested if the phylogeographic and genetic structures of these species are temporally consistent with the Pleistocene glacial refuge hypothesis. In this case, there woul...
Freshwater fishes are declining globally due to habitat loss, climate change, and other anthropogenic pressures. The Plains Sucker (Pantosteus jordani), recently recognised as a distinct species due to genetic and biogeographical factors, occurs east of the Rocky Mountains in Canada and the northern United States. Cana...
Globally, urban expansion and agriculture have driven widespread wetland degradation and loss. The Brolga (Antigone rubicunda), a wetland-dependent crane species distributed across northern and eastern Australia, is threatened in south-eastern states. In Victoria, census estimates remain below 1,000, and the species is...
Amphibian populations are strongly influenced by geographical and environmental barriers; however, the processes shaping the spatial genetic structure remain poorly understood in many East Asian taxa. We investigated the population structure and evolutionary history of the Korean endemic salamander Hynobius notialis...
