Morphological and nutritional characteristics of Gambel's Quail, Callipepla gambelii, in the greater Phoenix metropolitan area, Arizona (July-September 2015)
Gambel's Quail, Callipepla gambelii, are gregarious birds commonly found in the southwestern deserts of the United States and Northwestern Mexico. With expanding urbanization, these birds are often found in exurban and suburban areas where they have access to food sources that may differ from those used by birds living in rural-urban fringes. To investigate this question, we compared the morphology and nutritional physiology of quail sampled at sites varying with respect to land use and cover. We hypothesized that quail living in urbanized areas have access to a greater variety of food sources and to more stable food resources, and so are in better body condition, than quail residing in less urbanized areas. We sampled birds at locations in the Phoenix, Arizona (USA) area, that vary with respect to land use and cover types. Birds were weighed and we measured their body length and chest circumference. A blood sample was collected from the jugular vein of each individual for analysis of plasma glucose, total proteins, triglycerides, and free glycerol using commercially available kits. Consistent with our hypothesis, birds living in more urbanized environments were longer, and they had larger chest circumferences and greater circulating triglyceride concentrations than birds living in less developed areas, suggesting greater access to lipid-rich foods. In addition, the abundance of grass at the sampling sites was associated positively with plasma protein concentrations but negatively with plasma free glycerol levels. Areas with more grass may provide birds with less dietary fats than the diet of urban birds, resulting in the breakdown of triglycerides into free glycerol. These findings are the first to demonstrate an association between urbanization and the morphology and nutritional physiology of Gambel's Quail.

Historical specimens and the limits of subspecies phylogenomics in the New World quails (Odontophoridae)
<p>As phylogenomics focuses on comprehensive taxon sampling at the species and population/subspecies levels, incorporating genomic data from historical specimens has become increasingly common. While historical samples can fill critical gaps in our understanding of the evolutionary history of diverse groups, they also introduce additional sources of phylogenomic uncertainty, making it difficult to discern novel evolutionary relationships from artifacts caused by sample quality issues. These problems highlight the need for improved strategies to disentangle artifactual patterns from true biological signal as historical specimens become more prevalent in phylogenomic datasets. Here, we tested the limits of historical specimen-driven phylogenomics to resolve subspecies-level relationships within a highly polytypic family, the New World quails (Odontophoridae), using thousands of ultraconserved elements (UCEs). We found that relationships at and above the species level were well-resolved and highly supported across all analyses, with the exception of discordant relationships within the two most polytypic genera which included many historical specimens. We examined the causes of discordance and found that inferring phylogenies from subsets of taxa resolved the disagreements, suggesting that analyzing subclades can help remove artifactual causes of discordance in datasets that include historical samples. At the subspecies-level, we found well-resolved geographic structure within the two most polytypic genera, including the most polytypic species in this family, Northern Bobwhites (<em>Colinus virginianus</em>), demonstrating that variable sites within UCEs are capable of resolving phylogenetic structure below the species level. Our results highlight the importance of complete taxonomic sampling for resolving relationships among polytypic species, often through the inclusion of historical specimens, and we propose an integrative strategy for understanding and addressing the uncertainty that historical samples sometimes introduce to phylogenetic analyses.</p>
