Despite decades of studies on the differential distribution polyploid organisms, causes this pattern have yet to be elucidated. This study aimed explore some possible physiological mechanisms explaining northern clones Daphnia pulex compared one diploid parental species. The critical thermal minimum (CTmin) was measured in 17 D. contrasted ploidy (diploid and triploid) geographic origins (temperate subarctic climates) reared under low high temperatures (16 24°C). Triploid had better cold tolerance (lower CTmin) than both sympatric temperate clones. No significant association found between CTmin body size nor with cell size. We suggest that triploids might express a shock resistant phenotype related higher gene expression and/or fatty acid profiles. Cold can viewed as reasons for preponderance climates.

Polyploid organisms are common and can be found across the tree of life. A key question is to understand how why these polyploid lineages become established persist in populations, particularly since they predicted have a low probability success. While collection papers this special issue addresses broad questions on evolutionary ecology polyploids, ultimately, studies also highlight myriad ways that we examining what drives success lineages. In paper consider where we've been challenges face, then propose several directions will allow us continue propel field towards our ultimate goal understanding rules govern establishment persistence populations. We conclude developing rule set require combination model systems for which detailed knowledge phylogenetic population genetic history, expanding perspective beyond plants include greater taxonomic breadth, conducting ecologically relevant settings. Additionally, argue future research polyploidy should focus integrating theory empirical research, providing mechanistic linkages between effects whole genome duplication demography, build predictive framework anthropogenic change impact organisms.

Polyploidy, or whole-genome duplication (WGD), both a strong evolutionary and ecological force potential pitfall, occurs extensively across the tree of life, particularly in angiosperms. While polyploid organisms are prevalent, ancient polyploidy (paleopolyploidy) is decisively rare. Numerous studies have revealed adaptive changes at genomic, cellular, physiological levels that confer advantages to polyploids, but factors contributing their long-term success remain poorly understood. Here, we assembled large angiosperm genome dataset encompassing 470 different species. We reconstructed highly concordant timescale angiosperms conducted large-scale study identify date WGDs this set unveiled 132 independent WGD events do not seem randomly distributed time, clustered around periods great environmental upheaval. observed majority paleopolyploidizations occurred between 50 75 mya, coinciding with Paleocene-Eocene Thermal Maximum Cretaceous-Paleogene (K-Pg) boundary. A more recent wave can be 25 40 glaciation expansion, rapid shifts sea surface temperatures, marked decrease global mean temperature. Integrating lines evidence, argue polyploids an increased chance survival during times turmoil.
