Genomic characterization of a wild-like tomato accession from Arizona

Tomato domestication history has been revealed to be a highly complex story. A major contributor to this complexity is an evolutionary intermediate group (Solanum lycopersicum var. cerasiforme (Alef.) Voss; SLC) between the cultivated tomato (Solanum lycopersicum var. lycopersicum L.; SLL) and its wild relative (Solanum pimpinellifolium L.; SP). SLC includes accessions with a broad spectrum of genomic and phenotypic characteristics. Some of the SLC accessions were previously hypothesized to be spreading northward from South America into Mesoamerica and that migration probably entailed reversal to wild-like phenotypes such as smaller fruits. Prior to this study, the northernmost confirmed extension of the SLC was limited to northern Mexico. In this study, we employed genomic methods to investigate the origin of a wild-like tomato found in a garden in Scottsdale Arizona, USA. The so-called "Arizona tomato" featured a vigorous growth habit and carried small fruits weighing 2-3 grams. Our phylogenomic analyses revealed the identity of the Arizona tomato as a member of the Mexican SLC population (SLC MEX). To our knowledge, this is the first report of an SLC accession, confirmed using genomics, growing spontaneously in Arizona. This finding could have implications for conservation biology as well as agriculture.

Oligocene–Miocene exhumation of the Pinaleño metamorphic core complex, southeastern Arizona: support for magmatism and plate margin reorganization as controls on regional exhumation trends

We present thermochronology data from igneous and metamorphic rock samples collected from the Pinaleño Mountains, southeast Arizona, U.S.A.  Our interpretations of the data are described and discussed in a paper in the journal Tectonics, titled “Oligocene–Miocene exhumation of the Pinaleño metamorphic core complex, southeastern Arizona: support for magmatism and plate margin reorganization as controls on regional exhumation trends.”  New data include biotite and white mica Ar/Ar analyses, apatite fission track analyses, apatite (U-Th-Sm)/He analyses, and zircon (U-Th-Sm)/He analyses. The data were used for inverse HeFTy modeling and forward radiation damage and annealing modeling (RDAAM) to investigate time-temperature histories. The data set comprises a table summarizing the results of Ar/Ar analyses (Table S1), a table with the detailed results of zircon (U-Th-Sm)/He thermochronology (Table S2), a table with the detailed results of apatite (U-Th-Sm)/He thermochronology (Table S3), a table summarizing the results of apatite fission track analyses, including radial plots (Table S4), and a table summarizing the input data and constraints used for inverse modeling.

Mojave Bell's Sparrow (Artemisiospiza bellii canescens) and Sagebrush Sparrow (Artemisiospiza nevadensis) captures at western Arizona sites, February 2014

Bell's Sparrows (Artemisiospiza belli)) have only recently been recognized as distinct from Sagebrush Sparrows (A. nevadensis), and the "Mojave" subspecies (A. b. canescens) shares an overlapping wintering distribution with Sagebrush Sparrow in the Mojave and Sonoran deserts of southeastern California and western Arizona. We lack understanding of the 2 species' respective wintering habitat preferences and the degree to which they interact or segregate on their wintering grounds due to the difficulty in separating them in the field and to their previous classification as one species. We captured and sampled 74 Artemisiospiza sparrows from 5 sites across western Arizona, supporting field identifications with genetic analyses of mitochondrial DNA to confirm species and molecular sexing of sampled individuals. Bell's Sparrows and Sagebrush Sparrows segregated into different habitat types across our study area, with only one species detected at 4 of 5 study sites. Bell's Sparrows comprised 82 percent (n = 33) of Artemisiospiza sparrows captured at the 5th site at Robbins Butte. Broadly, Sagebrush Sparrows were found in more upland, well-drained locations that were sparsely vegetated with xerophytic scrub. Bell's Sparrows were found in more vegetated locations with halophytic Mojave seablite (Suaeda nigra) and saltbush (Atriplex) adjacent to mesquite and tamarisk woodlands. Bell's Sparrow sex ratios were significantly female-biased (binomial test: n = 56, observed k = 48 females, expected k = 28 females for assumed p = 0.5, Pr (k ≤ 8 or k ≥ 48) < 0.0001; 95% CI = 0.369 – 0.631 for assumed p = 0.5) at Fort Mohave and Robbins Butte, the 2 sites where Bell's Sparrows were found. Our observed sex-ratios and well-documented year-round presence of Bell's Sparrows on and near the breeding grounds suggest that Bell's Sparrow males and females employ different migration strategies, a phenomenon not previously documented for this taxon.
