\"Beloved American hero Buzz Aldrin reflects on the wisdom, guiding principles, and irreverent anecdotes he's gathered through his event-filled life--both in outer space and on Earth--in this inspiring guide-to-life for the next generation. Everywhere he goes, crowds gather to meet Buzz Aldrin. He is a world-class hero, a larger-than-life figurehead, best known of a generation of astronauts whose achievements surged in just a few years from first man in space to first men on the Moon. Now he pauses to reflect and share what he has learned, from the vantage point not only of outer space but also of time: still a non-stop traveler and impassioned advocate for space exploration, Aldrin will be 86 in 2016. No Dream Is Too High whittles down Buzz Aldrin's event-filled life into a short list of principles he values, each illustrated by fascinating anecdotes and memories, such as: \"Second comes right after first\": NASA protocol should have meant he was first on the Moon, but rules changed just before the mission; how he learned to be proud of being the second man on the Moon; \"Look for opportunities, not obstacles\": Buzz was rejected the first time he applied to be an astronaut; failure is an opportunity to learn to do better; \"Always maintain your spirit of adventure\": for his 80th birthday, Buzz went diving in the Galapagos and hitched a ride on a whale shark; he stays fit, energetic, and fascinated with life. No Dream Is Too High is a beautiful memento, a thought-provoking set of ideas, and a new opportunity for Buzz Aldrin to connect with the masses of people who recognize his unique place in human history\"-- Provided by publisher.

In migratory birds, population-genetic structure is generally low, but philopatric species can have fine-scale patterns of differentiation. We investigated the population-genetic structure of the Canada Goose (Branta canadensis) across multiple spatial scales to determine whether genetic data support current delineations of subspecies and populations for management. We collected samples from two subspecies (B. c. interior and B. c.maxima) and four management populations across Ontario and Quebec. Using 7 microsatellites and 442 base pairs of mtDNA we found that genetic structure varied with scale. FST revealed low levels of genetic differentiation between subspecies and management populations, and individual-based clustering revealed no genetic differentiation. However, fine-scale spatial autocorrelation revealed significant levels of relatedness at distances <85 km. The lack of clear genetic structure may reflect recent human management. That our fine-scale analysis revealed significant genetic relationships suggests that genetic structure may increase and in time reflect that revealed by banding data. As our markers were unable to accurately distinguish between subspecies they will be of little use in estimating subspecific contribution to harvested stock. Alternative molecular markers under selective pressure may be more informative in assess targets for harvest.

The parallel evolution of phenotypes or traits within or between species provides important insight into the basic mechanisms of evolution. Genetic and genomic advances have allowed investigations into the genetic underpinnings of parallel evolution and the independent evolution of similar traits in sympatric species. Parallel evolution may best be exemplified among species where multiple genetic lineages, descended from a common ancestor, colonized analogous environmental niches, and converged on a genotypic or phenotypic trait. Modern North American caribou (Rangifer tarandus) originated from three ancestral sources separated during the Last Glacial Maximum (LGM): the Beringian–Eurasian lineage (BEL), the North American lineage (NAL), and the High Arctic lineage (HAL). Historical introgression between the NAL and the BEL has been found throughout Ontario and eastern Manitoba. In this study, we first characterized the functional differentiation in the cytochrome‐b (cytB) gene by identifying nonsynonymous changes. Second, the caribou lineages were used as a direct means to assess site‐specific parallel changes among lineages. There was greater functional diversity within the NAL despite the BEL having greater neutral diversity. The patterns of amino acid substitutions occurring within different lineages supported the parallel evolution of cytB amino acid substitutions suggesting different selective pressures among lineages. This study highlights the independent evolution of identical amino acid substitutions within a wide‐ranging mammal species that have diversified from different ancestral haplogroups and where ecological niches can invoke parallel evolution. The parallel evolution of genotypes or phenotypes can provided information as to how selection can occur among lineages within a species. In caribou lineages from Eurasia and the North America, the patterns of amino acid substitutions occurring within different lineages supported the parallel evolution of cytB amino acid substitutions suggesting different selective pressures among lineages. This study highlights the independent evolution of identical amino acid substitutions within a wide‐ranging mammal species that has diversified from different ancestral haplogroups and where ecological niches can invoke parallel evolution.

\"Beloved around the world, Randy Travis has sold more than 25 million albums in both country and gospel and is considered one of the finest performers of his generation, admired by superstars across the musical landscape, from Garth Brooks to Mick Jagger. From a working-class background in North Carolina to a job as a cook and club singer in Nashville to his \"overnight success\" with his smash 1986 album Storms of Life--which launched the neotraditional movement in country music--Randy's first three decades are a true rags-to-riches story. But in 2009, this seemingly charmed life began a downward spiral. His marriage dissolved, he discovered that his finances had unraveled, and his struggles with anger led to alcohol abuse, public embarrassment, and even police arrest in 2012. Then, just as he was putting his life back together, Randy suffered a devastating viral cardiomyopathy that led to a massive stroke which he was not expected to survive. Yet he not only survived but also learned to walk again and in 2016 accepted his induction into the Country Music Hall of Fame by singing the hymn that explains his life today: \"Amazing Grace.\" Filled with never-before-told stories, Forever and Ever, Amen is a riveting tale of unfathomable success, great joy, deep pain, and redemption that can come only from above.\"--Amazon.com.

This article provides details of one approach for evaluating whether to install low‐pressure membranes as part of a water treatment plant (WTP) expansion. Even though the conventional WTP at the Modesto (California) Irrigation District (MID) was exceeding all state and federal water quality requirements, the decision was made to switch to a new filtration technology for the expansion. To verify the membranes' applicability and performance, the MID embarked on an extensive pilot testing program. It also evaluated options for residuals handling and for treating membrane cleaning wastes. Even a well‐operated conventional water treatment plant can have good reasons to expand with a newer technology, such as low‐pressure membranes. For the MID, the anticipated regional population growth and limited land for future water plant expansions, were significant reasons for expanding its conventional water plant with membranes. The authors have presented information that will be useful for utility managers facing their own treatment plant expansions by providing an example of one approach to evaluating a new technology for a plant expansion. Water utilities can see how MID proceeded with evaluation of low‐pressure membranes and how decisions were made. They can also learn about the design considerations for ozone, residuals handling, and disposal of membrane cleaning wastes. Readers will also be interested in the use of a siphon arrangement for drawing water through the membranes, a technique that will help to lower the overall energy use at the expanded facility.
