This book was released on 1993 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2Northern red oak acorn production was measured in 21 maturing stands on good sites in northwestern Pennsylvania. The number of acorns produced per acre varied from a low of 7,000 in a poor seed year to nearly 273,000 in a bumper year. Some acorns were produced in all years. In no year was there consistently good acorn production at all areas, nor was there a good crop for more than 2 consecutive years at any location. Acorn production was not related to the mean diameter and range of basal area of red oak trees in the experimental stands. Freezing temperatures when oaks were in flower was a major factor affecting acorn production on the Allegheny Plateau.S3.

Available in PDF, EPUB and Kindle. Book excerpt: Survival of recently fallen northern red oak acorns after exposure to a cool fall burn was determined on experimental plots in northwestern Pennsylvania. The fire consumed the leaf litter and fine woody material of the forest floor and was considered as a typical fall burn for this region. No acorns were consumed by the fire but some were charred. Between 40 and 49 percent of the acorns contained in the litter were killed. The fire was not hot enough to kill Curculio weevil larvae within the acorns. Burned acorns infested with Curculio that survived the fire had 20 percent lower germination rates than unburned acorns.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Acorns of red oaks (Quercus spp; Subgenus Erythrobalanus) are important forage for wildlife and seed for oak regeneration. I estimated production of viable acorns by red oaks in 5 forests in the Mississippi Alluvial Valley (MAV) and 2 greentree reservoirs (GTRs) in Mississippi. Mean acorn production in the MAV was 439 kg(dry)/ha of red oak crown (CV = 29%) during autumn-winter 2009-2010 and 794 kg/ha (CV = 19%) in GTRs during autumn-winters 2008-2010. I recommend researchers sample acorn production in the MAV for [greater than or equal to] 5 years to improve precision of estimates (i.e., CV [less than or equal to] 15%). I estimated mass and gross energy (GE) of viable red oak acorns after 90 days in unflooded and flooded hardwood bottomlands in Mississippi. Within species, mass loss of acorns was

Available in PDF, EPUB and Kindle. Book excerpt: The Study of Plants in a Whole New Light “Matt Candeias succeeds in evoking the wonder of plants with wit and wisdom.” ―James T. Costa, PhD, executive director, Highlands Biological Station and author of Darwin's Backyard #1 New Release in Nature & Ecology, Plants, Botany, Horticulture, Trees, Biological Sciences, and Nature Writing & Essays In his debut book, internationally-recognized blogger and podcaster Matt Candeias celebrates the nature of plants and the extraordinary world of plant organisms. A botanist’s defense. Since his early days of plant restoration, this amateur plant scientist has been enchanted with flora and the greater environmental ecology of the planet. Now, he looks at the study of plants through the lens of his ever-growing houseplant collection. Using gardening, houseplants, and examples of plants around you, In Defense of Plants changes your relationship with the world from the comfort of your windowsill. The ruthless, horny, and wonderful nature of plants. Understand how plants evolve and live on Earth with a never-before-seen look into their daily drama. Inside, Candeias explores the incredible ways plants live, fight, have sex, and conquer new territory. Whether a blossoming botanist or a professional plant scientist, In Defense of Plants is for anyone who sees plants as more than just static backdrops to more charismatic life forms. In this easily accessible introduction to the incredible world of plants, you’ll find: • Fantastic botanical histories and plant symbolism • Passionate stories of flora diversity and scientific names of plant organisms • Personal tales of plantsman discovery through the study of plants If you enjoyed books like The Botany of Desire, What a Plant Knows, or The Soul of an Octopus, then you’ll love In Defense of Plants.

Download or read book Estimating and Modeling Red Oak Acorn Yield and Abundance in the Mississippi Alluvial Valley written by and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Red oaks (Quercus spp.; Section Erythrobalanus) produce acorns which are valuable forage for wildlife especially mallards (Anas platyrhynchos) and wood ducks (Aix sponsa). Scientists have limited information on amount, timing, and persistence of these acorns in the Mississippi Alluvial Valley (MAV). Conservation planners rely on precise estimates of acorns and other forage to estimate habitat needed by waterfowl in the MAV and other regions. My study provided premiere landscape-scale, multi-year estimates of red oak acorn yield and on-ground abundance in the MAV. Mean yield of acorns was 534 kg(dry)/ha (42.3 acorns/ m2) across all sites, years (falls-winters 2009-2012), and oak species. Yield varied more within years (CV = 11 - 29%) than when data were combined across years (CV = 11%). Yield was not synchronized in any year among MAV sites. However, yield usually was synchronized among species within sites suggesting local factors influenced acorn yield more than landscape-scale factors. Among sites and years, acorn abundance generally was greatest in January (sample mean = 371 kg/ha) and least in November (198 kg/ha). Acorns persisted to February only in years of above-average yield. Except for Nuttall oak (Quercus texana), acorn persistence generally was stable regardless of yield from parent trees. Nuttall oak acorn persistence increased with yield perhaps revealing an evolutionary pressure that encourages masting. Red oak acorn abundance was linearly related to percentage of red oaks in the overstory, but this relationship differed in years of above- and below-average yield. Currently, conservation planners use 166 kg/ha as a forage estimate of red oak acorns, moist-soil seeds, and aquatic macro-invertebrates in bottomland hardwood forests with 100% red oak canopy. I sampled at 5 sites throughout the MAV over 3 years; therefore, I recommend conservation planners consider adopting my predicted estimate of 247 kg of acorns/ha of forest land with 100% red oak canopy. Because acorns persist through most winters and generally reach peak abundance in January, often concomitant with peak abundance of mallards and other ducks in the MAV, biologists and conservation planners may have undervalued the potential of bottomland hardwood forests to support ducks in mid-late winter.

Available in PDF, EPUB and Kindle. Book excerpt: “A timely and much needed call to plant, protect, and delight in these diverse, life-giving giants.” —David George Haskell, author of The Forest Unseen and The Songs of Trees With Bringing Nature Home, Doug Tallamy changed the conversation about gardening in America. His second book, the New York Times bestseller Nature’s Best Hope, urged homeowners to take conservation into their own hands. Now, he is turning his advocacy to one of the most important species of the plant kingdom—the mighty oak tree. Oaks sustain a complex and fascinating web of wildlife. The Nature of Oaks reveals what is going on in oak trees month by month, highlighting the seasonal cycles of life, death, and renewal. From woodpeckers who collect and store hundreds of acorns for sustenance to the beauty of jewel caterpillars, Tallamy illuminates and celebrates the wonders that occur right in our own backyards. He also shares practical advice about how to plant and care for an oak, along with information about the best oak species for your area. The Nature of Oaks will inspire you to treasure these trees and to act to nurture and protect them.
