ABSTRACT Understanding Neotropical megadiversity remains challenging due to fundamental taxonomic issues, including identifying and describing cryptic species and their distribution, and the limited knowledge of key factors driving biological diversification. Such challenges are especially prominent in diverse clades with high levels of cryptic species,

Estimating Speciation and Extinction Rates for Phylogenies of Higher Taxa [PDF]
Speciation and extinction rates can be estimated from molecular phylogenies. Recently, a number of methods have been published showing that these rates can be estimated even if the phylogeny is incomplete, that is, if not all extant species are included.

ABSTRACT Understanding insect responses to global climate change involves identifying strategies used during past climate oscillations. Phylogeography offers a powerful framework to unravel how historical climatic and geological events have shaped the spatial genetic patterns of species, providing critical insights into evolutionary processes, whereas ...

Can language be a valuable predictor of genetic diversity even at the level of extremely circumscribed areas of linguistic diversity? We report on the analysis of mtDNA and NRY variation extracted from the whole-genome sequencing of 27 natives of Grecìa ...

We molecularly characterized parrots (Amazona spp.) and macaws (Ara spp.) rescued from illegal trafficking in Colombia using two mitochondrial markers (COI and 16S rRNA). The COI gene showed high resolution for species identification and revealed considerable intraspecific diversity, while 16S rRNA displayed limited taxonomic resolution.

Structural and evolutionary dissection of NADPH‐binding motifs in NADPH‐preferring ene‐reductases
Abstract Ene‐reductases (ERs) catalyze nicotinamide‐dependent, stereoselective reductions of activated CC bonds. While their catalytic chemistry and applications are well‐explored, cosubstrate (NAD(P)H) binding remains poorly understood. Most ERs strongly prefer NADPH despite lacking canonical dinucleotide‐binding folds and instead employ flexible ...

Colletotrichum species with curved conidia from herbaceous hosts [PDF]
Colletotrichum (Glomerellaceae, Sordariomycetes) species with dark setae and curved conidia are known as anthracnose pathogens of a number of economically important hosts and are often identified as C. dematium.

Abstract Discordance among gene trees, including discrepancies with the species tree, is increasingly reported in analyses of phylogenomic data. Such discordance can result from technical issues such as misalignment, paralogy, or model misfit, or from biological processes such as incomplete lineage sorting (ILS), hybridization with introgression, or ...

Differences in mycelial turnover and persistence of wood‐decay fungi at the microscale
Summary How long do fungal hyphae persist in the environment? And how does this differ between groups and species of fungi? Despite growing knowledge of fungal contributions to decomposition and soil carbon cycles, surprisingly little is known about the turnover of mycelia: What happens to fungal hyphae over time? And how this impacts different fungi's

Summary Flowering of perennial Arabis alpina is differentially regulated on primary and axillary shoots. Although contributions of vernalization and ageing pathways have been analysed, those of photoperiodic flowering genes CONSTANS (CO), FLOWERING LOCUS T (FT), and TWIN‐SISTER OF FT (TSF) remain unexplored.
