Rotifers play key roles in aquatic ecosystems, yet significant uncertainty remains about their diversity and evolution, and further evidence is needed to determine how reliably their responses to global change and human impacts can inform conservation. To identify major knowledge gaps hindering progress, we carried out a Delphi process both online and during the 17 th International Rotifer Symposium, involving more than 40 exp...

Aim We investigated how local‐scale environmental heterogeneity influences biodiversity patterns across broad biogeographic gradients, using intertidal microhabitats as a model system within one of the most environmentally stressful ecosystems on Earth. Location Intertidal habitats at 26 locations (two rocky shore sites per location) across six continents, spanning 98° of latitude (38°S to 60°N). Time Period 2019–2022. Major T...

Coral limestone is an important building material worldwide. In this research, a limestone of coral origin (called múcara stone from Veracruz, Mexico) was subjected to weathering tests with the aim to develop an equation relating wet atmospheric deposition volume to stone damage. A two-year rain sampling campaign was performed in Veracruz, Mexico. The volume weighted mean (VWM) of major ions in precipitation was used to prepar...

Whilst it is established that almost all cultivated coffee ( Coffea arabica L.) varieties originated in Yemen after some coffee seeds were introduced into Yemen from neighboring Ethiopia, the actual coffee genetic diversity in Yemen and its significance to the coffee world had never been explored. We observed five genetic clusters. The first cluster, which we named the Ethiopian-Only (EO) cluster, was made up exclusively of th...

Much progress in speciation research stems from documenting patterns of morphological and genetic variation in hybrid zones. Contrasting patterns of marker introgression in different sections of the contact can provide valuable insights on the relative importance of various evolutionary mechanisms maintaining species differences in the face of hybridization and gene flow and on hybrid zone temporal and spatial dynamics. We stu...

Aim To devise a robust phylogenetic hypothesis for midwife toads ( Alytes : Anura: Discoglossidae) and to discuss its implications for the reconstruction of the biogeographical history of the group. Location Western Palearctic. Methods Analysis of sequences of mitochondrial DNA (cytochrome b and 16S RNA, 861 bp) and 29 characters of cranial osteology of all species and subspecies within Alytes . Results Phylogenetic analyses s...
