Facts

I was wondering around a week ago on facebook and found something very interesting. If you want to see what the world would look like if it was shrunken down to a village of 100 or so, this is what it would look like. You should ponder the questions at the end of this .jpg file.

Stimulus what?

President elect Obama stimulus package, on top of creating a higher national debt, in not giving enough tax benefits towards alternative forms of energy. Firstly, the majority of the energy that is produced in America is coming from coal...a dirty source of energy, no matter what is advertised on the television. Here is a what clean coal looks like. Secondly, our debt makes it so that we borrow money from China, which is a country that tries to poison, uses children for slave labor and unnecessarily imprison people for numerous violations for acts that should be free.

Lets re-evaluate where all of our money is going first, then use some of that money to stimulate our economy. Let stop feeding nations with war (i.e., Iraq, Israel, Afghanistan, Pakistan) and use some of that money to create jobs. Our nation would be so more secure if we didn't occupy other countries unnecessarily. We try to force our ideas onto others that do not want it. For that we are hated...

Here is more on the subject.

The thought of expanding technology and its impact on the environment has been a major concern in my mind. With new technology making new "stuff" and using more resources from this already stricken earth is disheartening. Mining for these resources has polluted our waterways and destroyed pristine natural habitat. The waste created is through technology is being tossed away into landfills. On US-27 south out of Oxford, OH, before entering Colerain, a business district before getting to Cincinnati, is the Rumpke Sanitary Landfill.

This is the view that I found as you travel north on US-27. The site is appalling. Almost 40% of waste is paper and I have read that 40% of that comes from businesses and corporations. Technology was supposed to cut down on waste be digitizing everything, but tons of waste is still generated. Most colleges has implemented ways to cut down on waste by recycling but what concerns me is the amount that is tossed into the recycling bins that is not recycled.

It has been said that technology will save us, but I am starting to doubt that. To know that other products has cut down on wastes is a light at the end of a tunnel (though the tunnel might be a hole that we are falling through and the light might be HELL) Getting back on topic, because my mind doesn't always follow a straight path, using computers to generate other forms of digital information has cut back on waste. Digitizing music into MP3 and putting them onto a device to listen to it instead of buying CDs in one thing. Also reading my morning news on slate.com on Green my Blog: The Best Way to Make a Web Site Energy Efficient has put hope back into society...somewhat. Lets try to do something about this. Lets not be a "throw away" generation and ultra consumer Americans. Lets try to create better places for future generations instead of making huge piles of waste for everyone to look at.

Mini-proposal for master's thesis

Over the past decade, increases in industrial agriculture have caused rapid declines in insect biodiversity because of the simplification of the landscape through the enlargement of crop field sizes and reduction of non-crop habitat (Bianchi et al. 2006). Non-crop habitat is necessary for a wide diversity of insects, especially for pollinators and natural predators for crop pests (e.g., Kremen et al. 2002, Tscharntke et al. 2007, Ricketts et al 2008). Natural habitat is beneficial for pollinators by supplying a diversity of nectar sources and nesting habitat (Kremen et al. 2004, Winfree et al. 2008) and is also beneficial for natural predators by supplying alternative hosts and overwintering sites (Bianchi et al. 2006, Vollhardt et al. 2008). Landscape management in an agroecosystem is needed to keep insect biodiversity in these natural habitats.

Connectivity between natural habitat in a landscape (i.e., an agroecosystem) enhances both diversity of natural predators and pollinators because high proportions of non-crop habitats have a greater diversity of natural predators and pollinators (Bianchi et al. 2006, Holzscheh et al. 2007). The economic value of these natural habitats to crop production is poorly understood. Theorectically, if land management practices are influenced by positive feedback through market forces then agroecosystems will become presumably more heterogeneous (Kremen et al. 2007).

Agricultural practices that increase insect biodiversity through increasing landscape complexity (Vollhardt et al. 2008, Tscharnke et al. 2007) and reducing or elimating pesticide input, would also increase the numbers of pollinators and natural predators within an argoecosystems (e.g., Holzschuh et al. 2007, Kremen et al. 2007, Winfree et al. 2008). Total diversity (gamma) on the landscape level is the combination of both the diversity within (alpha) and between (beta) habitats or patches (Clough et al 2007, Tscharntke et al. 2007). Tscharntke et al. (2007) hypothesized that as landscapes became more complex (i.e., more heterogeneous), then gamma diversity would increase. Beta diversity contributes significantly to total diversity because high beta diversity carries benefits for biological control through promoting predator-prey or parasite host systems at larger spatial scales. Higher beta diversity allows exploitation of heterogeneous pest populations because different natural enemies species have different microhabitat preferences (Tscharntke et al. 2007).

Conservation of biological control and pollinators is dependant on heterogeneous landscapes because intensely used homogenous landscapes with low species pools is unable to recover after a disturbance. The more complex a landscape becomes the quicker and more likely it will recover (Tschantke et al. 2007). Populations from adjacent habitats provide spatiotemporal complexity that allows for populations of natural enemies and pollinators to build up (Bianchi et al. 2006). This insurance (Yachi and Loreau 1999) buffers against fluctuations in ecosystem functioning by supporting higher species richness in a landscape.

To provide for a diversity of pollinators, nesting materials and nectar sources are needed. Determining how pollinators’ foraging range is affected by limited resources in nesting sites and/or floral resources are important area to look at. Changes in landscape alter the searching behavior of pollinators and their natural enemies. Top-down vs. bottom-up forces on pollinator’s relative abundance is another important area that needs to be identified (Kremen et al. 2007).

It is important to look at conservation biology in the agroecosystem on the landscape level because most arthropods are affected by spatial scales larger than their plot level. In the surrounding landscape, the species pools are important for the conservation of natural enemies and pollinators during the recovery period of species after a disturbance, especially for poorly-dispersing insects and specialized enemies (e.g., Kremen et al. 2002, Bianchi et al. 2006, Tscharntke et al. 2007, Ricketts et al 2008). I will test two hypotheses in my thesis. The first is, as complexity of landscape increases, the total diversity (gamma) increases is affected by beta (between) habitat or patch diversity than alpha (within) habitat or patch diversity, leading to higher pest control and pollinator relative abundances. Second I will to test the hypothesis that because of the loss of non-crop habitat, bottom-up forces have a greater effect to the biodiversity of natural enemies and relative abundances of pollinators as natural habitat decreases. I predict that as the landscape becomes more homogenous, the diversity of natural enemies and relative abundances of pollinators decline because of shrinking of the natural habitat that is required for there survival.

Within Butler and Preble counties in Ohio, I will be doing my study on Conservation Reserve Program (CRP) and Three-Valley Trust lands. CRP lands are part of the Natural Resources Conservation Services (NRCS) branch of the United Stated Department of Agriculture (USDA). The CRP provides assistance to farmers to address soil, water, and other related natural resources on their lands that will provide an environmental benefit to the lands in a cost-effective manner (Kremen et al. 2002). I will use a variety of techniques for collecting data, including a grid of combination pan/flight intercept traps, sweep sampling along transects within the interior and along edges of habitat patches, and patrolling fixed plots in a serpentine manner to estimate populations of butterflies, another common pollinator.

I will be using a number of tools to quantify biodiversity and abundances. Firstly, I will be using Geographical Information Systems (GIS) to explain connectivity and variation in a landscape. I will take waypoints in the field using a Geographic Positioning System (GPS) and used land cover to explain the variation inside a landscape. Secondly, I will also be focusing on specific species of a pollinator, a herbivore and a natural predator and use different matrices to explain alpha-, beta-, and gamma-diversity.

I expect to show that with lesser landscape heterogeneity, that the biodiversity of natural predators and abundances of pollinators will decrease with less natural habitat. I would expect that this is an effect from the bottom up because lack of resources required for these species to persist (e.g., Kremen et al. 2002, Tscharntke et al. 2007, Ricketts et al 2008). I also expect to see that as habitat heterogeneity decreases that species turn-over of both natural predators and pollinators to decrease because of the decreasing effect of beta-diversity on the total diversity (Clough et al 2007, Tscharntke et al. 2007).

life till now

What can I say? It has been a long winding road that I have been on with a lot of hills; some of them steep that it seems impossible to surmount...but somehow I manage. I have way to many things in my life going on at once, and I want more. Graduate school is kicking my ass, but somehow I managed a B and B+ in the two classes. My research is stagnant and seems to lead nowhere. Hopefully that will change once I get into the field. So what can I say up to now?

This is my first post to this site. I want to write to open peoples eyes to everything that is going on in this world that is wrong. I hope that other will help me. Global change. War. Destruction. Over-consumption. My graduate thesis follows some of these topics. I hope to post more and will because I will make time for this. I will be more structured.

My graduate thesis is on increasing in industrial agricultural and how it effects insect biodiversity and pollinator abundances. I am concern about pollinators, because they produce the fruit and vegetables that we consume. Once the honeybees are gone because of the sudden colony collapse, we loose the major pollinators. We still have other pollinators (e.g., true flies and other bees and wasps), but they are not as good. It is all because of homogeneous fields of corn, which is wind pollinated. The big fields of monocropping cuts back the natural habitat that other insects need for alternative food sources and nesting. This all comes back into the who over-consumptions of humans, especially Americans.

I hope to make this site as a basis of discussion for a lot of these topics, and I will promote this as much as I can as well as my friends site Under the Concrete. Let see if I can get this started...
