The allopolyploid complexes in Crocus series Verni represent taxonomic challenges due to their variable or mostly overlapping morphology with one parental species. Moreover, diploid ancestors remain unidentified, even genome-wide SNP data. One such case, collected from the southeasternmost point of series’ geographical distribution, is herein characterised and described as a new species, C. bachofenii. This study integrates phylogenomics cytogenetics infer origin bachofenii establish its diagnostic morphological characteristics. Genome skimming 10 other ser. species enabled development novel satellite repeats cytogenetic markers assembly complete chloroplast genomes that were employed for phylogenetic analysis alongside GBS (2n = 16) was confirmed vernus maternal parent. probably extinct paternal parent affiliated clade comprising heuffelianus, tommasinianus, kosaninii, bertiscensis. Morphologically, distinguished by larger flowers, perigone segment coloration, stigma–anther ratio close relatives. In conclusion, affiliation, distinctive cytological status, unique features justified description this taxon

The lakes known as El Sol and La Luna are high mountain water deposits located in Mexico within an inactive volcanic system. These of ecological importance because they unique Mexico. However, currently, the have experienced changes their shape increase algae blooms, coupled with degradation basin, which has alerted government entities to need address lakes’ problems. To environmental status Luna, a trophic study was conducted during period 2021–2023, including analysis influence climatic variables, lake quality, eutrophication conditions. state established based on index. Pearson correlations defined interrelation between distinct factors influencing status. registered higher conditions than Luna. identified seasonal eutrophic transitioning from oligotrophic mesotrophic, showing levels chlorophyll, total phosphorus, nitrogen low transparency. principal altering were pollution variables (precipitation ambient temperature). Eutrophication prime factor impacting perimeter loss at Sol, whereas it due decline precipitation.
