Summary: This study focuses on the thermal activity in the central part of the Sierra Madre Occidental in western Mexico. The anomalous water temperature of the thermal springs in this region is likely caused by heat production from radioactive decay, convection through deeply rooted faults, and the intersection of regional structures. The findings provide valuable insights into the geothermal system in this area.

Summary: This study aims to explicitly test whether the Sierra Madre del Sur includes areas with significant neo-, paleo- and mixed endemism and explore possible environmental drivers for their high species richness and spatial phylogenetic patterns. The results show that the distribution of species richness, endemism, and phylogenetic metrics in the area is heterogeneous. Neoendemism is mainly found in higher elevation pine-oak forests, while paleo-endemism is present in lower elevation pine-oak forests and seasonally dry tropical forests. Mixed and super-endemism are located in cloud forests and their ecotones with other forest types. The importance rating: 7 out of 10.

Summary: Several taxonomic novelties of the genus Sisyrinchium have been presented recently. A new species, Sisyrinchium jacquelineanum, was discovered in northwestern Mexico during a floristic inventory in a Natural Protected Area. It differs morphologically from the most similar species, S. polycladum, in terms of growth habit, position of root thickenings, absence of fibrous remnants of old leaves at the base of the stem, flower size, and capsule shape and pubescence. An identification key for the 16 species of Sisyrinchium in the Sierra Madre Occidental and their richness patterns are also provided.

Summary: This study generated niche models for 33 species of small, non-flying mammals in the Sierra Madre Occidental using Maxent and high-resolution physiographic layers. The resulting ecoregionalization proposed two major regions, tropical and xerophilous, with a transitional region between them. The complexity of the Sierra Madre Occidental goes beyond traditional subdivision based on the Nearctic-Neotropical division.
