Schwartz Soon after we came into extensive meadows: and I was assured that those meadows continue for a hundred and fifty miles. being in winter drowned lands and marshes. By the dryness of the season they were now beautiful pastures, and here presented itself one of the most delightful prospects I have ever beheld; all low grounds being meadow, and without wood, and all of the high grounds being covered with trees and appearing like islands: the whole scene seemed an elysium. Capt. Thomas Morris. 1791 I am sitting in a 60-mile-an-hour bus sailing over a highway originally laid out for horse and buggy. The ribbon of concrete has been widened and widened until the field fences threaten to topple into the road cuts. In the narrow thread of sod between the shaved banks and the toppling fences grow the relics of what once was Illinois: the prairie.

Available in PDF, EPUB and Kindle. Book excerpt: White-tailed deer (Odocoileus virginianus) have considerable impacts on woody and herbaceous vegetation. Many oak-hickory forests in the eastern U.S. are experiencing a lack of oak (Quercus) and hickory (Carya) regeneration, with deer being a likely culprit. Furthermore, few have studied deer use of different herbaceous food plot mixtures. I addressed these gaps in the literature by assessing deer impacts on forest and herbaceous vegetation in southern Illinois. I established 150 paired plots (enclosed and control) in June 2015 and measured 25 habitat variables to assess impacts of deer herbivory from August 2015 to August 2016. Oak seedlings were present more often and in higher numbers within enclosed plots (F1,299 = 6.25, P 0.050 and F1,387 = 4.50, P 0.050, respectively). There were no differences in the height of oak seedlings or the presence, number, or height of hickory seedlings in enclosed versus control plots (F1,53 = 0.010, P = 0.938; F1,299 = 0.850, P = 0.357; F1,267 = 1.16, P = 0.282; and F1,15 = 0.030, P = 0.855; respectively). During September-November 2015, I counted and marked fallen acorns within 50 random paired plots; the number of acorns discovered or lost did not differ between enclosed and control plots (F1,94 = 0.310, P = 0.578 and F1,8 = 0.120, P = 0.736, respectively). I suggest managers incorporate potential deer impacts when designing management plans to best encourage oak regeneration. During September-November 2015, I established 16 food plots (half tilled; each 0.05 ha in size), planted to 4 food plot types. I compared Big Tine Buck Brunch, Evolved Harvest Throw & Gro, Antler King No Sweat, and a food plot mixture that I created. I measured deer use via 2 methods: vegetation growth in exclosures versus control (i.e., unfenced) areas and camera traps. Deer used all 4 food plot mixtures (n = 292 - 2,522 pictures/plot over 9 weeks), having a negative impact on mean vegetation height outside of exclosures (F3,1148 = 6.71, P

This book was released on 2001-04-26 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological research and the way that ecologists use statistics continues to change rapidly. This second edition of the best-selling Design and Analysis of Ecological Experiments leads these trends with an update of this now-standard reference book, with a discussion of the latest developments in experimental ecology and statistical practice. The goal of this volume is to encourage the correct use of some of the more well known statistical techniques and to make some of the less well known but potentially very useful techniques available. Chapters from the first edition have been substantially revised and new chapters have been added. Readers are introduced to statistical techniques that may be unfamiliar to many ecologists, including power analysis, logistic regression, randomization tests and empirical Bayesian analysis. In addition, a strong foundation is laid in more established statistical techniques in ecology including exploratory data analysis, spatial statistics, path analysis and meta-analysis. Each technique is presented in the context of resolving an ecological issue. Anyone from graduate students to established research ecologists will find a great deal of new practical and useful information in this current edition.

This book was released on 2017 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ungulates are widely regarded as keystone herbivores and ecosystem engineers in ecosystems around the world. In forests of eastern North America, white-tailed deer (Odocoileus virginianus) can directly affect the presence, abundance, and reproductive success of many plant species via herbivory. Moreover, the direct effects of herbivory, along with the impacts of associated deer activities, may perturb the forest understory environment by altering the availability of understory light and soil resources. I used deer exclosures and motion-sensitive video cameras to explore the consequences of differing population densities of deer on understory environmental conditions, community composition, and interactions between deer, the environment and vegetation. I focused on several deer-mediated environmental factors including sapling abundance, light availability, soil compaction and thickness of the soil E horizon, in addition to other site characteristics including overstory cover and soil texture and chemistry. My three projects included a total of nine study sites that were scattered across northern Wisconsin and the Upper Peninsula of Michigan, USA, primarily in northern hardwood forests dominated by Acer saccharum. Across my study areas, herbivory was concentrated on woody regeneration within easy reach of deer. Environmental modifications wrought by deer browsing, such as higher light availability, soil compaction and thickness of the soil E horizon layer, affected the richness and abundance of native tree seedlings, shrubs and herbs, often in species-specific manners, and encouraged invasion by exotic species. Thus, I suggest a reexamination of the common assumption that understory community shifts in response to changes in deer abundance stem primarily from tissue removal and encourage further investigation of indirect mechanisms mediated by deer. Direct and indirect effects of abundant deer appeared to act in concert to diminish the efficacy of environmental variation to drive community heterogeneity, or the realized niche. With reduced deer abundance, particularly where overstory basal area was low, tree species richness increased. Such results provide evidence that silvicultural treatments like gap creation, in conjunction with deer control, can help reverse biotic homogenization of forest communities.
