Patterns of Genetic Diversity Within Three California Quail Species Are Best Explained by Climate and Landscape ChangesNARA Subscribed
Many North American game animals experienced severe population declines during the 19th century due to market hunting. However, estimates of the timing and magnitude of these declines often rely on anecdotal evidence, which makes it difficult to understand the lasting impacts of hunting pressures versus climate or landscape changes on the genetic diversity of contemporary populations. Historical reports suggest the California...
Reading tea leaves worldwide: Decoupled drivers of initial litter decomposition mass‐loss rate and stabilizationNARA Subscribed
The breakdown of plant material fuels soil functioning and biodiversity. Currently, process understanding of global decomposition patterns and the drivers of such patterns are hampered by the lack of coherent large‐scale datasets. We buried 36,000 individual litterbags (tea bags) worldwide and found an overall negative correlation between initial mass‐loss rates and stabilization factors of plant‐derived carbon, using the Tea...
Spatial variation in population genomic responses to over a century of anthropogenic change within a tidal marsh songbirdNARA Subscribed
Combating the current biodiversity crisis requires the accurate documentation of population responses to human‐induced ecological change. However, our ability to pinpoint population responses to human activities is often limited to the analysis of populations studied well after the fact. Museum collections preserve a record of population responses to anthropogenic change that can provide critical baseline data on patterns of g...
Common, low-frequency, rare, and ultra-rare coding variants contribute to COVID-19 severityNARA Subscribed
The combined impact of common and rare exonic variants in COVID-19 host genetics is currently insufficiently understood. Here, common and rare variants from whole-exome sequencing data of about 4000 SARS-CoV-2-positive individuals were used to define an interpretable machine-learning model for predicting COVID-19 severity. First, variants were converted into separate sets of Boolean features, depending on the absence or the pr...
Detecting introgression despite phylogenetic uncertainty: The case of the South American siskinsNARA Subscribed
Genetic introgression among closely related species is a widespread phenomenon across the Tree of Life and could be an important source of adaptive variation during early stages of diversification. In particular, genomic studies have revealed that many rapidly radiating clades tend to have complex, reticulate evolutionary histories. Although rapid radiations appear to be susceptible to introgression, they present special chall...
Biogeography of the Andean metaltail hummingbirds: contrasting evolutionary histories of tree line and habitat‐generalist cladesNARA Subscribed
Aim To assess geographical and temporal patterns of diversification in Metallura hummingbirds, particularly with respect to topographical barriers and climatic variation between different populations. Location Tropical Andes. Methods We estimated a multilocus phylogeny for all nine species of Metallura and evaluated phylogeographical patterns within Metallura tyrianthina using mitochondrial DNA sequences from across its range...
Tree mineral nutrition is deteriorating in EuropeNARA Subscribed
The response of forest ecosystems to increased atmospheric CO 2 is constrained by nutrient availability. It is thus crucial to account for nutrient limitation when studying the forest response to climate change. The objectives of this study were to describe the nutritional status of the main European tree species, to identify growth‐limiting nutrients and to assess changes in tree nutrition during the past two decades. We anal...
