Understanding the biogeographical patterns, and evolutionary and environmental drivers, underpinning morphological diversity are key for determining its origins and conservation. Using a comprehensive set of continuous morphological traits extracted from museum collections of 8353 bird species, including geometric morphometric beak shape data, we find that avian morphological diversity is unevenly distributed globally, even after controlling for species richness, with exceptionally dense packing of species in hyper-diverse tropical hotspots. At the regional level, these areas also have high morphological variance, with species exhibiting high phenotypic diversity. Evolutionary history likely plays a key role in shaping these patterns, with evolutionarily old species contributing to niche expansion, and young species contributing to niche packing. Taken together, these results imply that the tropics are both 'cradles' and 'museums' of phenotypic diversity.

Understanding the diversity of microscopic hyphomycetes is an ongoing effort, and many species remain undescribed. While studying lichen organismal composition in western Canada, metagenomic data revealed the presence of an unknown species of (, Ascomycota), a genus of pollen-parasitic fungus with no previous records in the region. We developed genus-specific primers to amplify DNA in lichen and adjacent substrate extractions, successfully detecting multiple lineages of across a wide geographic range within North America.

Pollination is essential for maintaining biodiversity and ensuring food security, and in Europe it is primarily mediated by four insect orders (Coleoptera, Diptera, Hymenoptera, Lepidoptera). However, traditional monitoring methods are costly and time consuming. Although recent automation efforts have focused on butterflies and bees, flies, a diverse and ecologically important group of pollinators, have received comparatively little attention, likely due to the challenges posed by their subtle morphological differences.

Objective: The terminal Pleistocene is a crucial stage in the formation and differentiation of modern populations. Recent studies show that the population during this period had significant morphological variability and regional divergence. The objective of this study was to investigate the Yahuai-1 (YH1) from the Yahuai Cave site in southern China to understand human morphological diversity and population dynamics during the terminal Pleistocene in Southern East Asia.

The genus Hill ex Schrank is an ecologically significant group of wood-decaying fungi that contribute to nutrient cycling and ecosystem stability in forests worldwide. Despite a recent global increase in the descriptions of new species, Korean species have rarely been reexamined using modern taxonomic frameworks. In this study, dried specimens preserved at the Korea National Arboretum were re-identified through integrative morphological and molecular analyses using four genetic markers (ITS, ACT, TUB2, and RPB2).
