Relative Differences

A field experiment was established between 1989 and 1993 to study the effects of competing vegetation on growth of planted Norway spruce (Picea abies (L.) Karst.) seedlings. Effects of clearcut age, scarification (mounding), herbicide treatment, and seedling stock type were investigated 5 years after planting. On fresh clearcuts, amounts of vegetation were negligible, whereas 2.1-3.7 Mg·ha-1 was found on 4-year-old and older clearcuts. Soil temperatures were about 10% higher in mounds than in undisturbed ground, while herbicide and clearcut age only marginally affected soil temperatures. Seedlings planted on old clearcuts showed significant reductions in growth due to interference from vegetation. Five years after planting, the reduction in growth corresponded to about 1 year's growth. Most of the interaction between seedlings and vegetation occurred during the first 2 years after planting. Thus, scarification was just as effective as repeated herbicide treatments in reducing competition from vegetation. Differences in periods of drought between years could largely explain variation in leading shoot length. However, leading shoot length was affected in the same way irrespective of vegetation control treatments. Five years after planting, the relative differences in diameter between bare-root and containerized seedlings were the same as at the time of planting.

The Impact

Abstract Work in other species has demonstrated an impact of gestational exposure on flavor preferences. Although equine palatability preferences in mature horses have been identified, feeding behaviors in growing horses are not well documented. The objective of this study was to evaluate the impact of exposure to common palatants in utero on feeding preferences of weanlings. Stock-type weanlings (n = 4) weighing 225(±18.15) kg at 29(±2.55) weeks of age were used in a side-by-side comparison test with a divided feeding platform. Common palatants (apple and anise) were utilized throughout the broodmare gestational period. A novel palatant, peppermint, was withheld during gestation to identify impacts associated with neophobic tendencies. Treatments were offered once daily for three consecutive days across three periods (4 weeks apart) using a pelleted concentrate feed with an application rate of 0.375 mL/0.23 kg. Weanlings were allowed free access to the feeding platform with identical pans spaced 6” apart for 20 minutes. Treatment location within the feeding platform was changed daily to limit effects associated with side-eating. Data were measured as a Chi Square test of SAS using PROC FREQ statement with α ≤. 0.05. Despite gestational exposure to apple and anise, no preference was measured in palatability assessments including First Sniff (P = 0.29), First Consumed (P = 0.70), First Finished (P = 0.29). These data suggest that exposure in utero failed to elicit a preference for common palatants in weanling horses. Additionally, these data fail to demonstrate a neophobic effect for a novel palatant, peppermint.

AbstractThere is a shift in livestock auction sales in consolidation of live markets and movement toward virtual marketplaces. We examine buyer preferences for nonracing stock-type horses sold through virtual auctions to better understand how animals are sold and their valuation. A shift towards online sales of equine has impacted the number of potential buyers through increased exposure to sale horses. Using data collected from online auctions, we estimate factors influencing propensity to sell as well as price determinants in this market platform. We find many factors contribute to the likelihood of a horse selling and to the final sale price.

The Relationship

This paper explores the relationship between firm size and sustainable innovation in large international firms. To this end, we develop a labor demand framework. The contribution to the literature is to explore external knowledge in determining the employment impact of sustainable innovation. Our investigation is based on firms in three economic areas: Europe, Japan, and the United States. In this way, we will appreciate the extent to which the technological spillovers are important from a geographical perspective. The findings provide evidence of the significance of spillover effects on a firm’s size; however, these effects depend on the spillover stock type.

Simulated Browsing

Animal herbivory is a major limiting factor to successful oak (Quercus spp.) regeneration. Although bare-root seedlings are the most commonly used nursery stock type for oak plantings in the eastern United States, container seedlings may better resist planting stress and help enable seedlings to overcome browsing pressure. Four stock types (1 + 0 bare-root seedlings and seedlings in 164, 336, and 520 mL containers) of northern red oak (Quercus rubra L.) were planted on two reforestation sites in Indiana, USA, which were fenced to exclude white-tailed deer (Odocoileus virginianus Zimmerman). Seedlings were then subjected to three simulated browsing treatments (control unclipped, dormant clipped, and summer clipped). Container seedlings exhibited higher relative growth rates on both sites; for example, at one site, control seedlings in 336 mL containers had relative height growth of 558% compared with 79% for bare-root control seedlings. On both sites, summer-browsed seedlings of all stock types had negligible height growth, and summer browsing reduced survival at one site by 23% for all stock types compared with control seedlings. Browsing of seedlings during the dormant period did not affect growth for any stock type. Container seedlings may help facilitate rapid establishment of planted oak seedlings, but browse protection is necessary to ensure oak regeneration success in areas of large populations of deer.

Abstract Oxidative stress (OS) causes health complications through the destruction of cellular components as individuals age. Reactive oxygen species are used to measure OS through Trolox equivalent antioxidant capacity (TEAC) and thiobarbituric acid reactive substances (TBARS). Other prebiotics have been used to reduce OS markers in numerous species; however, the effect of short-chain fructooligosaccharides (scFOS) on OS has not been studied in the horse. Ten healthy stock-type horses were blocked by age into 2 groups: mature (MA; n = 5; 7.0 ± 0.87 yr) and senior (SR; n = 5; 22.6 ± 1.1 yr) to analyze effects of scFOS on TEAC and TBARS. Horses were randomly assigned to 1 of 3 diets for 25 d before transition to another diet. Diets were bermudagrass hay offered at 1.5% BW/d hay as-fed, hay with a ration balancer (CON), or hay with a ration balancer and scFOS added at a rate of 2.5 g/kg (PRE). Prior to a total fecal collection for an alternate study, horses were fasted overnight for 8 h with blood samples taken immediately prior to feeding (0), 30, and 60 min postprandial. Oxidative stress markers were analyzed for the 2 ration balancer diets. Statistical analysis was performed with SAS using the MIXED procedure with horse within diet as a random effect with significance of P ≤ 0.05. Trolox equivalent antioxidant capacity was unaffected by diet (P = 0.827) or age (P = 0.347). Time (P = 0.006) was significant for TBARS which increased postprandial regardless of treatment or age. Consistent with other species, higher levels of OS was found in SR compared to MA regardless of time or diet (P = 0.037; 4.491 µM vs. 3.412 µM TBARS, respectively). These results indicate that scFOS do not seem to be effective in reducing OS in SR and MA horses.

From a sustainable material management perspective, vacant houses represent material stock and still have potential in the circular economy. This article addresses two aspects of understanding and managing vacant houses: the difficulty of understanding their spatial and temporal patterns and the management of the social costs behind the phenomenon of vacant houses. These aspects are approached by combining a 4D GIS analysis with expert interviews and additional qualitative tools to assess the spatial and temporal dimension of vacant houses. Furthermore, this manuscript presents a tool to estimate the obsolete dwelling material stock distribution within a city. The case of the city of Kitakyushu demonstrates the relationship that exists between the historical trajectories of housing norms and standards, such as comfort, cleanliness, safety, and convenience, and the dynamics of the built material stock and demography for three selected neighbourhoods. The results show that the more locked-in a district is in terms of “obsolete norms and codes”, the more likely it is that the obsolete stock is dead, and consequently, urban mining should be considered. The article concludes that a revisiting of the norms and standards of convenience and other domains is one of the prerequisites of the transition toward a circular built environment and the prevention of obsolete stock accumulation.
