In 1958, writer Rachel Carson began her exhaustive research on the effects of widespread pesticide use for her next book, Silent Spring. Over the next four years, she built up an airtight case showing how the world’s most powerful chemical companies were harming animals, plants, and people. Her effort was also a race against time, as she struggled against an aggressive form of breast cancer. In the second episode of a four-part special series on leadership, HBR Editor in Chief Adi Ignatius and Harvard Business School professor and historian Nancy Koehn trace the modern environmental movement back to Carson’s pioneering reporting and powerful prose. They discover lessons in how to strengthen your resilience, gather your energy and skills for a coming challenge, and why caretaking is an act of leadership.

Rapeseed husks, filtered matter and liquid rejects branch out on arrows to the right. Extract from the T4 separation stage (‘Extrakt als Ruckfuhrung’) is fed back into the second node although this loop is not shown here.

Whitebark pine is a critical component of subalpine ecosystems in western North America, where it contributes to biodiversity and ecosystem function and in some communities is considered a keystone species. Whitebark pine is undergoing rangewide population declines attributed to the combined effects of mountain pine beetle, white pine blister rust, and fire suppression. The restoration and maintenance of whitebark pine populations require an understanding of all aspects of seed fate. In this paper, we review the literature on seed dispersal in whitebark pine. Clark's nutcracker, pine squirrels, and scatter-hoarding rodents are all known to influence whitebark pine seed fate and ultimately affect the ability of whitebark pine populations to regenerate. We also provide a general overview of the natural histories of the most influential species involved with whitebark pine seed fate: Clark's nutcracker and the pine squirrel.

Four types of tree shelters were evaluated in southwestern Washington for their effects on seedling microenvironment and performance of two tree species. Shelter types were fine-mesh fabric shelters, solid-walled white shelters with and without vent holes, and solid-walled blue unvented shelters. Summer mean and daily maximum air temperatures were increased by 0.8 degrees C and 3.6 degrees C, respectively, in solid-walled tree shelters. Shelter color and shelter venting did not influence air temperatures. Tree shelters only affected vapor pressure deficit late in the growing season. Midday photosynthetically active radiation within shelters ranged from 54 percent of full sun in fine-mesh fabric shelters to 15 percent of full sun in blue solid-walled shelters. In the first year after planting, height and diameter growth of western redcedar (Thuja plicata Donn ex D. Don) were significantly increased by all shelter types, with blue solid-walled shelters resulting in the greatest height growth. However, in blue solid-walled shelters, photosynthesis and stem diameter growth of Oregon white oak (Quercus garryana Dougl. ex Hook.) seedlings were significantly less than for unsheltered seedlings.

This study's objective was to document and describe the current seedling bank of Sitka spruce (Picea sitchensis (Bong.) Carr.) and western hemlock (Tsuga heterophylla (Raf.) Sarg.) stands in southeast Alaska that were partially cut between 1900 and 1984.

In dry, open coniferous forests of the montane West, stand-replacing wildfires and land use activities alter the composition and abundance of native grasses and forbs by degrading the habitat and accelerating the invasion of exotic annuals. On these lands, native forbs and grasses delayed or prevented from recovery by natural processes may require intervention through supplementary seeding. However, effective seeding of native plants requires that their seed traits and the potential outcome of the seeding be better understood.
