The Role of Awns Evolution in Shaping the Biogeographical History of Pappophorinae (Poaceae: Chloridoideae)

Journal of Biogeography, Volume 53, Issue 3, March 2026.
ABSTRACT Aim We reconstructed the biogeographic history of Pappophorinae and tested whether the evolution of awns is associated with differences in species' geographic ranges. Location Americas. Time Period Miocene. Major Taxa Studies Pappophorinae (Poaceae: Chloridoideae).

Patterns of Interploidy Admixture in Polyploid Complexes: Insights From Thymus Sect. Mastichina (Lamiaceae)

Molecular Ecology, Volume 35, Issue 3, February 2026.
ABSTRACT Understanding gene flow between ploidy levels in polyploid complexes is essential for species delimitation and conservation. This study explores evolutionary dynamics in the polyploid complex Thymus sect. Mastichina (Lamiaceae), comprising three taxa: T. mastichina subsp. mastichina, T. mastichina subsp.

Frog Diversity in Central Amazonian Macrophyte Beds: The Role of Local Environmental Gradients

Austral Ecology, Volume 50, Issue 12, December 2025.
ABSTRACT Ecological assemblages can be shaped by neutral, niche‐based processes, or a combination of both. Understanding the influence of these processes and evaluating diversity measures based on taxonomic, functional, and phylogenetic metrics on the structure of ecological assemblages can show patterns and unravel community assembly mechanisms ...

The Hidden Diptera Diversity in Aristolochia Trap‐Flowers: Revealing the Identity of Pollinators Through Taxonomic Knowledge

Journal of Applied Entomology, Volume 149, Issue 10, Page 1502-1512, December 2025.
ABSTRACT Although Diptera is one of the most diverse insect orders with a high potential for pollinating plants, it remains poorly studied and neglected. This is partly due to limited taxonomic efforts in species identification. For instance, despite being primary pollinators of trap flowers, species‐level identification in these systems remains scarce.
