Much research has been conducted on the resource curse, the idea that development of natural resources can reduce economic growth. There are a variety of reasons why an abundance of natural resources might reduce economic growth, including a phenomenon referred to as Dutch Disease where a boom in local resource production leads to increased costs for other sectors. A sudden end to the resource boom or when other sectors have a higher growth rate than...

Seadragons are widely recognized for their derived and novel traits. Research and conservation efforts involving these unique fish species and their relatives have been hindered by a lack of genomic resources. From this project we present full, annotated genomes of leafy and weedy seadragons, which help uncover surprising features of gene family and genome architecture evolution that likely relate to extreme phenotypic traits in seadragons, pipefishes, and seahorses. These genomes are important research resources for...

Numerous novel adaptations characterise the radiation of notothenioids, the dominant fish group in the freezing seas of the Southern Ocean. To improve understanding of the evolution of this iconic fish group, we generated and analysed new genome assemblies for 24 species covering all major subgroups of the radiation, including five long-read assemblies. We present a new estimate for the onset of the radiation at 10.7 million years ago, based on a time-calibrated phylogeny derived from...

Background:We evaluated imaging features suggestive of neurodegeneration within the brainstem and upper cervical spinal cord (UCSC) in non-progressive multiple sclerosis (MS).Methods:Standardized 3-Tesla three-dimensional brain magnetic resonance imaging (MRI) studies were prospectively acquired. Rates of change in volume, surface texture, curvature were quantified at the pons and medulla-UCSC. Whole and regional brain volumes and T2-weighted lesion volumes were also quantified. Independent regression models were constructed to evaluate differences between those of Black or African ancestry (B/AA)...

Understanding the phenotypic and genetic architecture of reproductive isolation is a longstanding goal of speciation research. In several systems, large-effect loci contributing to barrier phenotypes have been characterized, but such causal connections are rarely known for more complex genetic architectures. In this study, we combine ‘top-down’ and ‘bottom-up’ approaches with demographic modeling toward an integrated understanding of speciation across a monkeyflower hybrid zone. Previous work suggests that pollinator visitation acts as a primary barrier to...

Single cell RNA sequencing (scRNAseq) is a powerful technique that continues to expand across various biological applications. However, incomplete 3’ UTR annotations can impede single cell analysis resulting in genes that are partially or completely uncounted. Performing scRNAseq with incomplete 3’ UTR annotations can hinder the identification of cell identities and gene expression patterns and lead to erroneous biological inferences. We demonstrate that performing single cell isoform sequencing (ScISOr-Seq) in tandem with scRNAseq can rapidly...

Biologists recognize the Caribbean archipelago as a biodiversity hotspot and employ it for their research as a “natural laboratory”, but do not always appreciate that these ecosystems are in fact palimpsests shaped by multiple human cultures over millennia. We discuss two case studies of the Caribbean’s fragmented natural history collections, the effects of differing legislation and governance by the region’s multiple nation states. We use digital natural history specimen data from GBIF to demonstrate how...

Ungulate migrations are crucial for maintaining abundant populations and functional ecosystems. However, little is known about how or why migratory behavior evolved in ungulates. To investigate the evolutionary origins of ungulate migration, we employed phylogenetic path analysis using a comprehensive species-level phylogeny of mammals. We found that 95 of 207 extant ungulate species are at least partially migratory, with migratory behavior originating independently in 17 lineages. The evolution of migratory behavior is associated with reliance...

These data are based on tree-ring data from the internation tree ring data base and PRISM climate data.

Visual input during natural behavior is highly dependent on movements of the eyes and head, but how information about eye and head position is integrated with visual processing during free movement is unknown, since visual physiology is generally performed under head-fixation. To address this, we performed single-unit electrophysiology in V1 of freely moving mice while simultaneously measuring the mouse’s eye position, head orientation, and the visual scene from the mouse’s perspective. From these measures, we...

Does drought stress in temperate Pacific Northwest, USA, grasslands alters the relationship between plant structure and function? Here we report data from an experiment focusing on growth form and species traits that affect the critical functions of water- and nutrient-use efficiency in prairie and pasture plant communities. A total of 139 individuals of 12 species (11 genera and four families) were sampled in replicated plots maintained for three years across a 520 km latitudinal gradient...

Abstract Background An essential determinant of a neuron’s functionality is its neurotransmitter phenotype. We previously identified a defined subpopulation of cholinergic neurons required for social orienting behavior in zebrafish. Results We transcriptionally profiled these neurons and discovered that they are capable of synthesizing both acetylcholine and GABA. We also established a constellation of transcription factors and neurotransmitter markers that can be used as a “transcriptomic fingerprint” to recognize a homologous neuronal population in another vertebrate....
