You probably know that buying in bulk is a great way to reduce packaging and get a rock bottom price. Another perk is that it keeps spoiled food and dollars from going down the drain — that’s because bulk bins allow you to select only the amount you need.

Summary: Understanding the determinants of the length of food chains is of fundamental importance to ecologists. Food chain length influences the potential complexity of the community, patterns of biomass in each trophic level, and possible biomagnification of harmful substances (e.g. mercury or DDT, Post 2002). There are many factors that may affect food chain length and debate over the importance of each has recently intensified (Post 2002). Additionally, very little is known about the functioning of urban ecological communities. Here we examine the influence of resource availability (water), disturbance (wind), and ecosystem size (number of plants) on the food chain length of arthropod communities inhabiting brittlebush (Encelia farinosa) at the Desert Botanical Gardens, a remnant desert site located in the urban Phoenix, AZ area. To do this we set up a field experiment consisting of 108 sets of replicate brittlebush locations, subject to three levels of watering (resource availability; one, three, or seven times per week), leaf blower wind (disturbance; none, once, or twice per month), and number of plants (ecosystem size; 1, 2, or 3 plants in sets). Our preliminary results suggest that water increases and wind decreases food chain length in brittlebush arthropod communities, and that there is a potential interaction between these two variables. Our results suggest no support for an effect of ecosystem size (number of plants in replicate sets) on FCL, though total plant volume may exert a heretofore unmeasured effect. Overall, our results suggest strong climatic control on the length of food chains on this naturally occurring plant in desert cities.

Strolling down one of our world-famous canal banks in 2025, it’s hard to imagine that a renaissance of greater Phoenix was launched in 2009 during the nation’s economic meltdown. With the financial and real estate industries in tatters and major infrastructure in decline, Valley leaders nevertheless joined forces and seized the opportunity to implement bold, yet practical new ideas for creating a truly sustainable urban place.

Five new solar initiatives totaling $4 million dollars to advance Arizona’s renewable energy leadership
PHOENIX – Science Foundation Arizona announced its new solar technology initiatives and the opening of the Solar Technology Institute (STI) on April 17, with simultaneous events at the APS Star Facility in Phoenix and Global Solar in Tucson.
In a collaborative effort, STI is deploying Arizona’s significant solar resources with industry and the research strengths of Arizona State University (ASU) and the University of Arizona (UA) to grow the state’s global leadership in renewable energy. STI is being led by two pioneers in the solar field, Robert “Bud” Annan and Richard Powell, to serve as co-directors. The Stardust Foundation is assisting in the financial support of the investments.

Communication is the basis of all social relationships between animals. Birds use acoustic signals (calls and songs) to attract and bond with mates, defend territories and warn of danger from approaching predators. Background noise reduces the distance over which a call or song can be heard. As well as natural noises (e.g. wind and rain), birds in urban habitats must compete with human-generated noise such as road-traffic noise, much of which occurs in the lower-frequency bands below 2,000 Hz. Birds in cities have been known to use a number of strategies for overcoming noise, such as singing at a higher pitch to reduce masking by the low-frequency noise, singing more loudly, or singing at night time when traffic noise is at its lowest.
I travelled to Phoenix to investigate the how birds there respond to traffic noise. In a collaborative project with researchers from GIOS and SoLS at ASU, I recorded the calls and songs of birds and measured noise levels at 24 neighbourhood parks around the city. We are particularly interested to see whether doves such as the Inca dove and mourning dove are calling at a higher pitch in noisy areas. Of all the birds that live in cities, we would expect them to have the most difficulty hearing each other in traffic noise. This is because they have very low-pitched calls that are overlapped by the low-pitched traffic noise. But these species are very common around Phoenix, which suggests that they can still attract mates and breed successfully in noisy urban environments. In the future, we would like to investigate the breeding success of doves in noisy and quiet locations, to see whether urban noise is actually having an impact on their populations.

“In periods of great flux and uncertainty, the people who love [change] are going to find opportunities,” says Andrew J. Hoffman, the author of Climate Change: What’s Your Business Strategy? (2008). Speaking to an ASU audience and reporters on Mar. 19, the University of Michigan professor of sustainable enterprise cast climate change as both a threat and an opportunity.

Eric Williams, an assistant professor of civil, environmental and sustainability in the Ira A. Fulton School of Engineering, is interviewed on a segment of the program Sustainability, which aired recently on National Public Radio, including local Phoenix-area affiliate station KJZZ-91.5 FM.
The show focuses on projects that scientists and engineers are working on to solve many of the world’s environmental problems.
Williams talks about his National Science Foundation-funded search for solutions to the growing worldwide problem caused by a proliferating amount of “e-waste.” That’s a short way of referring to all the junk we are creating when we toss out our old and used electronic equipment, especially computers.
Williams suggests ways we could properly recycle computer components or keep old computers in use. That way the chemicals and materials would not pile up on waste heaps and threaten to do environmental damage by finding their way into soils and water sources.
The segment begins about 18 minutes and 15 seconds into the 50 minute show (the entire program is worth a listen). Sustainability is part of the Global Challenges Series from the Purdue University College of Engineering.

What comes to mind when you look across grasslands? That they are major components of “drylands,” regions that cover more than 40 percent of the world’s land area and home to more than 25 percent of the global human population? Or, rather, lyric phrases, such as “Leaves of Grass” and “Amber waves of grain?”

Whispered rumors have reached us about a dedicated band of “Recycling Gurus” on ASU campuses who can enlighten students on how to improve the ecological footprints of their residence halls. The Gurus’ mantra for recycling compactors: “No glass, no plastic bags, no pizza boxes.” Repeat 50 times, please. We tracked down two of the Recycling Gurus and in a Q&A with the duo found out what makes them tick. Hailing from the Center Complex dorms, freshman Mechanical Engineering and Sustainability students Andrew Latimer and Alex Davis tell us more about their lives as Recycling Gurus…
