We report the plaque propagation and genomic analysis of Xfas53, a temperate phage of Xylella fastidiosa. Xfas53 was isolated from supernatants of X. fastidiosa strain 53 and forms plaques on the sequenced strain Temecula. Xfas53 forms short-tailed virions, morphologically similar to podophage P22. The 36.7-kb genome is predicted to encode 45 proteins. The Xfas53 terminase and structural genes are related at a protein and gene order level to P22. The left arm of the Xfas53 genome has over 90% nucleotide identity to multiple prophage elements of the sequenced X. fastidiosa strains. This arm encodes proteins involved in DNA metabolism, integration, and lysogenic control. In contrast to Xfas53, each of these prophages encodes head and DNA packaging proteins related to the siphophage lambda and tail morphogenesis proteins related to those of myophage P2. Therefore, it appears that Xfas53 was formed by recombination between a widespread family of X. fastidiosa P2-related prophage elements and a podophage distantly related to phage P22. The lysis cassette of Xfas53 is predicted to encode a pinholin, a signal anchor and release (SAR) endolysin, and Rz and Rz1 equivalents. The holin gene encodes a pinholin and appears to be subject to an unprecedented degree of negative regulation at both the level of expression, with rho-independent transcriptional termination and RNA structure-dependent translational repression, and the level of holin function, with two upstream translational starts predicted to encode antiholin products. A notable feature of Xfas53 and related prophages is the presence of 220-to 390-nucleotide degenerate tandem direct repeats encoding putative DNA binding proteins. Additionally, each phage encodes at least two BroN domain-containing proteins possibly involved in lysogenic control. Xfas53 exhibits unusually slow adsorption kinetics, possibly an adaptation to the confined niche of its slow-growing host.

Hispanics are a growing segment of the United States population and will be an increasingly important stakeholder in future allocation and management of natural resources, including wildlife. In the United States, Hispanics now are the largest ethnic minority and will remain so over the next 40 years. Texas supports the second‐largest Hispanic population in the United States behind California, and it will have a Hispanic majority by 2040. Some analysts predict that this demographic shift will leave us with a less‐educated population with smaller incomes and higher levels of poverty—posing not only a social concern but also a challenge for conservation of wildlife resources. Here we identify shared Hispanic cultural characteristics, such as family, socioeconomic factors, and language, and their importance in planning wildlife outreach programs. Recognizing differences among Spanish‐speaking cultures is equally important. Knowledge of cultural characteristics will enable wildlife advocates to better expose wildlife issues in a manner receptive by Hispanics. It is in the best interest of wildlife and wildlife professionals to encourage Hispanic participation in this planning process because of their growing political and economic influence.

Latinos in the United States are an increasing segment of the population and are becoming important stakeholders in the management of natural resources. Although Latinos have been included in attitudinal research on environmental concerns, few studies have focused exclusively on Latino attitudes toward natural resources and the environment. We surveyed Texas college and university students of Mexican descent (n = 635) to determine their environmental concerns. Using the New Ecological Paradigm (NEP), we determined an environmental concern score for each respondent and compared this index to several demographic variables. We found that gender, a political candidate's environmental position, mother's education, combined parental income, and, to a lesser degree, the number of grandparents born in the United States and religiosity (church attendance), were important model variables. We hypothesized that acculturation would be an important factor in predicting NEP scores; however, acculturation level was not an important predictor in our study, which we attribute to both the nature of our sample (i.e., highly acculturated college students) and small sample sizes of less‐acculturated college students. We recommend that future research consider determining the importance of acculturation in Latino attitudes toward natural resources and the environment.
