Speciation, dispersal and the build‐up of fern diversity in the American tropics
Ecography, EarlyView.Understanding how the remarkable biodiversity of the American tropics developed has been a long‐standing question, yet knowledge gaps remain. Previous studies examined the roles of bioregions in shaping diversity patterns but often overlooked speciation, a critical driver of species richness, and insufficiently accounted for temporal changes in ...

An isothermal workflow for low‐cost and PCR‐free field‐based community metabarcoding
Methods in Ecology and EvolutionDNA metabarcoding has revolutionized our ability to monitor ecosystems. However, the method is still rarely used in developing countries where resources are limited and fieldwork is challenging.

Earth History and the Evolution of Caribbean Bats [PDF]
, 2009 Although the natural history of the Caribbean is better understood now than ever before, a general biogeographic explanation for the peculiar faunal composition of the islands remains elusive.

iMetaOmics, EarlyView.This study showed that four Mycobacterium tuberculosis complex (MTBC) sub‐lineages might be introduced into China 1000–400 years ago via Europe‐China dispersal routes, where they diversified into local clades, and later underwent population expansions that coincided with periods of climatic cooling and warfare.

Integrative Conservation, EarlyView.Accurate species identification is critical for conserving endangered Firmiana trees in China. However, morphological similarities among closely related Firmiana species complicate its taxonomic identification. We conducted genome skimming on 62 samples representing all 10 Chinese species and discovered nrITS as the optimal DNA barcode, achieving 100 ...

Making vertebrate fossil radiocarbon dates more useful for global scientific research
Journal of Quaternary Science, EarlyView.ABSTRACT Radiocarbon dating of bones is essential for reconstructing timelines of species' occurrences, domestication, extinction, migrations, and interactions with Quaternary environments. Many studies compile these chronologies at continental to global scales by aggregating radiocarbon dates from various sources, often balancing data quantity and ...

Limnology and Oceanography, EarlyView.Abstract Nitrogen fixation, the microbial reduction of dinitrogen to ammonia, is increasingly recognized to occur in the Arctic Ocean. However, knowledge about the composition, biogeography, abundance, and ecology of nitrogen‐fixing organisms (diazotrophs) is poor.

Aquatic fungal diversity assessment through metagenomics is still limited to current databases
Limnology and Oceanography, EarlyView.Abstract Fungi play essential roles across ecosystems, yet their diversity in aquatic environments remains poorly understood compared to terrestrial systems. To address this gap, we analyzed metagenomes from 26 lakes in the boreal and subarctic zones, along with one tropical reservoir, to characterize fungal and fungal‐like (Oomycota) community ...
