Did incentives help municipalities recover from the Great Recession? Evidence from Midwestern cities

This study assesses the impacts of local business incentives in the largest urban areas of Illinois, Michigan, and Wisconsin, three Midwestern states that share similar histories and settings. We assembled a unique dataset combining information on two types of incentives, tax increment financing districts and tax abatements, together with socio‐economic, geographic, fiscal, and spatial competitive characteristics for all of the municipalities in six metropolitan areas. The outcome measures include employment growth, establishment formation, and business relocation. The analysis extends knowledge of the effects of economic development incentives in two ways. First, we improve upon previous research by incorporating key factors in municipal decisions to offer incentives. Second, we add to limited empirical evidence concerning local incentives following the Great Recession. Variation in the use of incentives reflects not only local decision‐making but also differing fiscal capacities and situations of adaptation to adverse economic conditions, with some governments pulling back on incentives and others initiating new approaches to retain or lure businesses.     

What factors influence the stem taper of <Emphasis Type="Italic">Eucalyptus</Emphasis>: growth,environmental conditions,or genetics?

• Introduction   

Stem taper equations have been widely used for volume estimation to varied top diameter limits or for biomass calculations. However, their main drawback is that specific calibration is often necessary for each species or clone, and accounting for genetic and environmental effects is often a challenge.     

Keystone effects of the endangered Stephens' kangaroo rat (Dipodomys stephensi)

Kangaroo rats (Dipodomys) have been argued to exert keystone effects because they interact strongly with other species, and their removal results in major changes in community structure. We evaluated the nature and magnitude of such impacts by the endangered Stephens' kangaroo rat (Dipodomys stephensi), employing an exclosure experiment to determine how the removal of this species impacted relative cover by vegetation, plant species diversity, abundance of a dominant annual plant genus (Erodium), and predation of seeds from artificial trays. Fifteen months of D. stephensi removal resulted in significant increases in herb cover and Erodium abundance, and significant declines in bare ground and in seed predation. These results support the hypothesis that D. stephensi has major impacts on plant community structure and seems to function as a keystone species. It remains to be seen how the loss of this species from much of its range will influence local community composition and dynamics.     

Surgical correction of periocular fat pads and entropion in a potbellied pig (Sus scrofa)

A 16-year-old Vietnamese potbellied pig was examined because of recurrent ocular discharge and reduced visual ability. Bilateral upper eyelid entropion and impaired vision secondary to periocular fat deposition were diagnosed. Surgical correction with excision of subdermal fat and redundant skin was performed to address both issues. Surgery restored vision and resolved ocular irritation. More than 1 year following surgical therapy the pig is visual and comfortable with no evidence of recurrent fat deposition or entropion.
