Relocated, range-limited, but resilient: niche shift and constraints on spread in introduced Nanday parakeets (Aratinga nenday)NARA Subscribed
Introduced species often encounter novel environments that test their capacity for ecological flexibility and adaptation. We investigated ecological niche dynamics in Nanday Parakeets ( Aratinga nenday ), a naturalized parrot species in Los Angeles, to assess whether their introduced range reflects a shift from their native range in South America. Using principal components analysis and niche overlap tests, we found that the i...
Aim After environmental disasters, species with large population losses may need urgent protection to prevent extinction and support recovery. Following the 2019–2020 Australian megafires, we estimated population losses and recovery in fire‐affected fauna, to inform conservation status assessments and management. Location Temperate and subtropical Australia. Time period 2019–2030 and beyond. Major taxa Australian terrestrial a...
Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disab...
TRY plant trait database – enhanced coverage and open accessNARA Subscribed
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodivers...
Phylogeography of ants from the Brazilian Atlantic ForestNARA Subscribed
How are nitrogen availability, fine‐root mass, and nitrogen uptake related empirically? Implications for models and theoryNARA Subscribed
Understanding the effects of global change in terrestrial communities requires an understanding of how limiting resources interact with plant traits to affect productivity. Here, we focus on nitrogen and ask whether plant community nitrogen uptake rate is determined (a) by nitrogen availability alone or (b) by the product of nitrogen availability and fine‐root mass. Surprisingly, this is not empirically resolved. We performed...
Adapting Stand‐Alone Renewable Energy Technologies for the Circular Economy through Eco‐Design and RecyclingNARA Subscribed
Summary Renewable energy (RE) technologies are looked upon favorably to provide for future energy demands and reduce greenhouse gas (GHG) emissions. However, the installation of these technologies requires large quantities of finite material resources. We apply life cycle assessment to 100 years of electricity generation from three stand‐alone RE technologies—solar photovoltaics, run‐of‐river hydro, and wind—to evaluate enviro...
Genome‐wide signals of drift and local adaptation during rapid lineage divergence in a songbirdNARA Subscribed
The formation of independent evolutionary lineages involves neutral and selective factors, and understanding their relative roles in population divergence is a fundamental goal of speciation research. Correlations between allele frequencies and environmental variability can reveal the role of selection, yet the relative contribution of drift can be difficult to establish. Recently diversified taxa like the Oregon junco (Aves,...
Aim The aim of our study was to reconstruct ancestral geographic distributions from time‐calibrated phylogenies generated from phylogenomic data to answer three broad questions about the biogeography of skinks in the Plestiodon brevirostris group: (1) Are biogeographic patterns correlated with the formation of the Trans‐Mexican Volcanic Belt? (2) Do different methods of phylogenetic estimation result in different topologies? I...
Genomic studies are revealing that divergence and speciation are marked by gene flow, but it is not clear whether gene flow has played a prominent role during the generation of biodiversity in species‐rich regions of the world where vicariance is assumed to be the principal mode by which new species form. We revisit a well‐studied organismal system in the Mexican Highlands, Aphelocoma jays, to test for gene flow among Mexican...
Genomic data reveal ancient microendemism in forest scorpions across the California Floristic ProvinceNARA Subscribed
The California Floristic Province ( CFP ) in western North America is a globally significant biodiversity hotspot. Elucidating patterns of endemism and the historical drivers of this diversity has been an important challenge of comparative phylogeography for over two decades. We generated phylogenomic data using dd RAD seq to examine genetic structure in Uroctonus forest scorpions, an ecologically restricted and dispersal‐limi...
Next‐generation phylogenetics takes rootNARA Subscribed
It has been a tumultuous 5 years in phylogeography and phylogenetics during which both fields have struggled to harness the power of next‐generation sequencing ( NGS ) (Ekblom & Galindo ; McCormack et al . ). Fortunately, several methodological approaches appear to be taking root. In this issue of Molecular Ecology , O'Neill et al . ) employ one such method – parallel tagged sequencing ( PTS ) – to elucidate the phylogeography...
Landscape genetics is an emerging discipline that utilizes environmental and historical data to understand geographic patterns of genetic diversity. Niche modelling has added a new dimension to such efforts by allowing species–environmental associations to be projected into the past so that hypotheses about historical vicariance can be generated and tested independently with genetic data. However, previous approaches have prim...
