Dwarf forms of Pinus rigida inhabit a variety of environments where stress factors (nutrient deprivation, drought, wind, and salt spray) and fire disturbances are strong selection factors within the local biological community. Pinus rigida morphology in stressed and disturbed communities ranges from medium sized trees to dwarf and prostrate trees forms. I selected three communities where Pinus rigida exhibited stress adapted morphology including the...

Wolves (Canis spp.) have recolonized the Great Lakes region (GLR) and expanded into agricultural areas, resulting in an increase in predations on livestock and domestic dogs (n = 121), seasonality of predations on livestock, and the association between previous winter severity and predations on livestock, and the association between previous winter severity and predations on livestock, in the Upper Peninsula of Michigan, U.S.A., between 15 April 1996...

Rusty Blackbird Euphagus carolinus populations have suffered a steep decline in the past few decades, but the reasons for this decline remain unclear. Until recently little information was known about the species' ecology due to its secretive nature and the remoteness of its breeding habitats in the boreal forest, but the recent development of a working group of biologists to study the species is rapidly improving our knowledge of the species. A number...

"When Jennifer Doudna was a sixth grader in Hilo, Hawaii, she came home from school one afternoon and found a book on her bed. It was The Double Helix, James Watson's account of how he and Francis Crick had discovered the structure of DNA, the spiral-staircase molecule that carries the genetic instruction code for all forms of life. This book guided Jennifer Doudna to focus her studies not on DNA, but on what seemed to take a backseat in biochemistry:...

"Weaving his own moving family story with this sweeping history of cancer research, Lawrence Ingrassia delivers an intimate, gripping tale that sits at the intersection of memoir and medical thriller"--
