Forest Defoliation By And Invasive Outbreak Insect: Catastrophic Consequences For A Charismatic Mega Moth, Richard L. Lindroth, Mark R. Zierden, Clay J. Morrow, Patricia C. Fernandez

Aspen Bibliography

Earth is now experiencing declines in insect abundance and diversity unparalleled in human history. The drivers underlying those declines are many, complex, and incompletely known. Here, using a natural experiment, we report the first test of the hypothesis that forest defoliation by an invasive outbreak insect compromises the fitness of a native insect via damage-induced increases in toxicity of the forest canopy. We demonstrate that defoliation by the invasive spongy moth (Lymantria dispar) elicits an average 8.4-fold increase in foliar defense expression among aspen (Populus tremuloides) genotypes. In turn, elevated defense dramatically reduces survivorship, feeding, and …

Simulating The Long-Term Response Of Forest Succession To Climate Change In The Boreal Forest Of Northern Ontario, Canada, Guy R. Larocque, F. Wayne Bell, Eric B. Searle, Stephen J. Mayor, Thomas Schiks, Parvin Kalantari

Aspen Bibliography

The effect of climate change on forest dynamics is likely to increase in importance in the forthcoming decades. For this reason, it is essential to predict the extent to which changes in temperature, precipitation, and atmospheric CO₂ might affect the development of forest ecosystems and successional pathways. The gap model ZELIG-CFS was used to simulate the potential long-term effects of climate change on species-specific annual change in mean basal area and stand density under two scenarios of representative concentration pathways (RCP), 4.5 and 8.5, for the boreal forest region of Ontario, Canada, where mean temperature, precipitation, and atmospheric CO …

Chinese Tallow Long-Term Impact On Stand Dynamics In A Bottomland Hardwood Forest Following Vegetation Management, Nicklaus R. Langlois

Electronic Theses and Dissertations

Chinese tallow (Triadica sebifera (L.) Small) is an invasive tree known to have negative impacts on bottomland hardwood forests. Chinese tallow is proficient in reproducing and surviving in bottomland hardwood forests because it is more flood and shade tolerant than most native trees. The long-term effectiveness of Chinese tallow control is an important topic to research as only a few long-term studies of Chinese tallow control have been conducted. A 10-year re-measurement of 22 paired plots installed in 2012 on the Pineywoods Mitigation Bank near Diboll, Texas following herbicide treatments examined Chinese tallow and native tree stand structure.

Turkish Journal of Agriculture and Forestry

Global crop yield and growth are severely impacted by hazardous heavy metal contamination of the soil and water. This study examined the effects on a range of physiological, biochemical, and morphological parameters of two canola (Brassica napus L.) cultivars, Punjab (V1) and Super (V2), when they were subjected to three different levels of cadmium (Cd) stress (0, 1.5, and 2.25 mM) and foliar application of biostimulant, i.e., Moringa leaf extract (MLE). Plants in V1 (Punjab) collect more Cd in both their aerial and subterranean sections than in V2 (Super).The morphological and physiological indicators showed a substantial (p < 0.05) deterioration as a result of the Cd buildup. Ascorbic acid and malondialdehyde (MDA) and hydrogen peroxide (H2O2) were considerably (p < 0.05) elevated under Cd stress. V1 has considerably higher H2O2 values than Super (V2), which suggests that oxidative stress levels there are higher. Additionally, the activity of some antioxidant enzymes, such as catalase and peroxidase (65 and 40%, respectively), were reduced by a higher concentration of Cd (2.25 mM). V2 demonstrated stronger antioxidant defence mechanisms than V1, as seen by a 115% rise in POD activity, a 70% increase in shoot fresh weight, and a 49% increase in amino acids following MLE spray. Despite this, the V2 was still able to withstand Cd. Under Cd stress, foliar treatment of MLE increased both kinds' yield, growth, biochemical, and physiological characteristics. The findings indicated that applying MLE foliar spray can improve crop productivity and lessen the impacts of metals on B. napus L.

Carbon In Non-Forested Wetlands Of The Midwest And Eastern United States, Adrienne B. Keller, Stephen D. Handler

Michigan Tech Publications

Although wetlands make up a small percentage of total land area in the United States, they store a disproportionate amount of carbon largely due to their unique hydrology. Wetlands of the Midwest and Eastern regions are comprised of both mineral soil wetlands and organic soil wetlands (peatlands) and store a significant proportion of all wetland carbon in the contiguous United States. Here, a basic summary of how carbon is stored and moves through these wetlands, and how climate change and management may interact with site conditions to alter wetland carbon cycling, is provided.
