Bark beetle outbreaks are often fueled by drought and fire-damaged trees, killing more trees and exacerbating the effects of climate change (CFPC 2015). This paper will be focusing on the decline of one of California’s most abundant species, the Ponderosa pine (Pinus ponderosa). Ponderosa pine trees have a wide range and can be found throughout the western United States, southern Canada, and northern Mexico (Little 1971). Here in California they primarily occupy mountainous regions but have been found in elevations ranging from sea level to 10,000 ft. depending on latitude (Oliver and Ryker 1990). Ponderosa pines are susceptible to further decline as we continue to see increases in temperature and drought in California. It is inevitable that we will continue to see changes in our forest structures so long as we continue to manipulate and influence the natural world. However, what will these changes mean for the health and well-being of humans and wildlife? P. ponderosa is a beautiful tree that provides scenery, solace, and enjoyment to humans and crucial habitat for birds, mammals, insects, and associated understory plant species. Future forest management decisions depend on thorough interdisciplinary solutions to major problems like the bark beetle attacks and…
Look for branches breaking near the trunk, slits in the bark, woodpecker injury and chewed on foliage on ash trees. “EAB can wreak havoc in your cemetery, causing huge risk and budgetary issues. Spot EAB warning signs early. Or, you risk losing 15 to 30 percent of all the trees on your property within 3 to 5 years,” cautioned Borkowicz. If you spot a tree risk, call a trained arborist for help. “Preventive tree care can save thousands of dollars in potential damage or tree removal later on,”…
Malicious A twisted tree trunk protrudes out of the silt like earth, covered in crude knots and lanky dead branches; the trunk hovers over the small stretch of land it sits upon. The rough, callous bark of the foreboding tree a dark hazel splattered with sections of sunken grooves. A shadow casts upon the intruding tree, darkening the bottom section of the once splendid trunk to a sinister shade of black. The upper top half on the trunk splintered, as if its own structure and size had betrayed…
Rickie Williams Zoology Ms. Julie Lady Bugs (Coccinellidae) Research paper Introduction Lady bugs are a part of the Coleoptera order. According to University of Arkansas, United States department of Agriculture and County Governments Cooperating Coleoptera is identified by two pairs of wings; front pair hard and shell-like, and hind pair is membrane like. Their mouth part is chewing and their metamorphosis is complete. According to Turkish Journal of Zoology Lady bugs are predator insects. They…
forests has emerged in the form of two invasive species of beetles, the Asian Longhorned Beetle and the Emerald Ash Borer. Both beetles are major pests of widespread forest and neighborhood trees, and if left unchecked, have the potential to completely change the character of our forests. Although not as widely known as some higher-profile environmental issues, invasive species like the Asian Longhorned Beetle and the Emerald Ash Borer are nevertheless one of the greatest problems facing the…
oxygen and consume carbon dioxide. If the trees are killed by the fires, it can lead to a rise in carbon emission, since there are no trees around and burning trees can also cause the release of carbon dioxide. The more greenhouse gases the trees release will in turn to create stronger effects for the global warming. Second of all, the insect outbreak is also affected by global warming. The survival of insects and diseases is largely depend on climate. Due to the warmer and wetter conditions by…
Adaptations allow certain animals to live in certain environments/habitats, these adaptations are crucial for the survival of an organism. Group 2 - Insects Insects are able to survive on land or in water. Both land insects and aquatic insects do the same gas exchange process however both have different adaptations that allow them to live in either land or water. A diving beetle and a mayfly are both good examples of how insects have adaptations that allow them to live in the water and be fully…
always busy with work. The only person that could be said to be close to him was his sister, who would turn on him later in the story. Upon metamorphosis, Gregor could no longer provide for himself, which wasn't a problem, or his family who, he was most worried about. From the point of this major physical change from a human to a beetle, his family starts to turn on him. This is due to the fact that Gregor had no longer acquired the ability to work to work and provide for his family. After…
will starve. It messes up the whole reproduction process. Another way climate change impacts is causing to relocate or migrating up north because it 's now available. An issue in the gulf of Maine has showed up in the past few years. That issue is that the waters are warming up the fastest than any place on earth. This causes fish such as cod and herring to leave. Maine fisheries have been having to shut down creating major job loss and are going to continue to close because scientists predict a…
This is because each species fills a specific ecological niche, by being adapted to that environment. The loss of one species affects another as any species that will take over the niche will not be able to replace the function of the original species. They are important in maintaining the ecosystem services such as photosynthesis, biological control of pests, nutrient recycling, control of climate, pollination and treatment of microbial waste. Dung Beetles, play an important role in…
