Summary: During the Late Pleistocene, there were ice sheets covering parts of North America. However, it is unclear whether ice-free refugia existed in the Alexander Archipelago along the SE Alaska coast during the last glacial maximum (LGM). Genetic analyses of black and brown bears in SE Alaska show that there were two subclades of black bears, one preglacial and one postglacial, that diverged over 100,000 years ago. Ancient brown bears are closely related to modern brown bears in the archipelago, suggesting colonization after the LGM. These findings suggest that there were no refugia in SE Alaska during the LGM, but vegetation quickly expanded after deglaciation.

Summary: The study revealed complex genetic structure and historical evolution of Magnolia tree species in the Tropical Montane Cloud Forests of Mexico, influenced by Pleistocene climatic fluctuations. Environmental factors played a crucial role in genetic differentiation, with demographic expansions predating the Last Interglacial period. Conservation management of genetically diverse populations in remnant forest fragments in the three TMCF regions is essential for the protection of these Magnolia populations.

Summary: This study conducted a geomorphic investigation and modeling analysis to evaluate the debris flow process in postglacial terrain. The results showed that volcanic tephra soils and timber harvest are important controls on debris flow occurrence. The application of the SHALSTAB model successfully predicted areas of high landslide potential. This study demonstrates the practical utility of hazards analysis in postglacial landscapes.

Summary: The study found that the dietary behavior of Yukon gray wolves has remained consistent over time, with no significant changes in their consumption of flesh rather than bone. They have been generalist predators, feeding on several large ungulate species for thousands of years. The extinction of megafaunal species around 11.7 ka led to a shift in their diet from horses to cervids, such as moose and caribou, with the survival of large-bodied cervids being crucial for wolf survival.

Summary: This study investigated the impact of climatic, geographical, and historical factors on earwig species richness and composition in Italy. The results showed that the richness of earwig species in Italy does not follow a clear geographical pattern, but is positively correlated with precipitation. Inter-regional similarities in species composition are more influenced by geographical proximity rather than climatic similarity. There is a decrease in similarity with central European fauna as we move southward, suggesting possible species exchanges between central Europe and Italy. The isolation of ancient earwig populations on Italian mountains has led to the development of a large number of endemic species, making the Italian earwig fauna one of the richest in Europe.

Summary: This study reanalyzes contemporary and ancient Canis DNA genomes to more accurately estimate divergence dates among lineages, and reviews literature on Late Pleistocene Canis distributions to identify potential progenitors and ancient hybridization events. The proposed Beringian gray wolves and extinct large wolf-like coyotes may represent previously unrecognized sources of introgressed genomic variation within contemporary Canis genomes.

Summary: A study on the White-backed Woodpecker using multilocus molecular data and species distribution modelling revealed genetic differentiation among subspecies and discussed the colonization history of the Japanese archipelago. The results suggest a historical split between the leucotos and lilfordi lineages and a possible eastward population expansion from a glacial refugium in Central Europe.

Summary: Research has shown that Quaternary climate fluctuations can impact the assembly of regional biodiversity in the European Alps. Endemic fish species may have evolved through adaptive radiation, while endemic amphipods may have originated from ancient populations with limited range expansion and local Pleistocene survival. Terrestrial endemics mainly formed in the Pleistocene, influenced by the glacial species pump.

Summary: This study used high-throughput sequencing technology to analyze the genetic diversity and structure of the critically endangered montane shrub, Lonicera oblata, and identified important conservation units. The results showed low genetic diversity and high genetic differentiation among populations. Two drastic population size contractions and the possibility of glacial refugia were also inferred from the data.

Summary: Recent studies have questioned the prevailing paradigm about the Quaternary ecological and evolutionary history of Central European ecosystems, and proposed an alternative hypothesis. By synthesising recent advances in various research fields and analysing the cold tolerance of native flora, it was found that the flora in the Carpathian Basin has long-term continuity. This has important implications for understanding local biogeography and ecology, as well as developing conservation strategies for ancient species-rich ecosystems and local gene pools.

Summary: This study aims to investigate the effect of climatic oscillations during the Pleistocene glaciation on the diversification pattern and evolutionary history of hemipteran insects. By studying the mitochondrial genome and nuclear ribosomal RNA genes of spinous assassin bugs, we found that the five species are highly diverged, with three of them being cryptic. Our analysis suggests that this genus may have experienced climate-driven habitat fragmentation and postglacial expansion in the Pleistocene, promoting allopatric speciation and intraspecific diversification.

Summary: The glaciations during the Pleistocene had a significant impact on the distribution of temperate species in Europe. This research shows that the effects of glaciations on the genetics of temperate species are more complex than previously believed, uncovering the existence of multiple glacial refugia across Europe.

Summary: The study found that despite the unequal climatic niches among the three Cerastium taxa, they share similarities in their overall phylogeographic structure, suggesting similar underlying processes and responses to historical events. It is anticipated that these taxa will respond differently to ongoing climate warming.

Summary: The study reveals stable wolverine populations in Northwest Alaska since at least the Last Glacial Maximum, minimal divergence in Southeast Alaska without genetic signatures of long-term refugial persistence, and mixed characteristics on the Kenai Peninsula indicating a more recent colonization history. The findings support the notion of a distinct subspecies of wolverines on the Kenai Peninsula and provide valuable data for informing conservation and management strategies.

Summary: The discovery of genetically distinct hantaviruses in multiple species of shrews, moles and bats reveals a complex evolutionary history involving cross-species transmission. Different viruses, such as SWSV, ALTV, LENV, and ALTV-related viruses, have been found in various shrew species in different regions, suggesting a diverse and geographically widespread distribution pattern. These findings hint at the emergence of new hantavirus species through ancient cross-species transmission and subsequent diversification within Sorex shrews in Eurasia.

Summary: Limited sampling obstructs effective management for imperiled taxa, hindering understanding of ecological and evolutionary processes and impeding conservation efforts. Researchers have discovered eight new locations for the endangered New Mexico Meadow Jumping Mouse, expanding their known distribution across three states. Future predictions indicate complex changes, including regional expansion and unsuitability of half of the designated critical habitat areas by 2070. A holistic sampling strategy is needed to fully document the distribution and facilitate genomic analyses for improving understanding of geographic variation and adaptive potential.
