8 pages, This study examined the impact of replacing soybean meal (SBM) for treated and untreated sesame meal (SM) with varying amounts of crude protein (CP) on nutrient intake and digestibility, milk composition, and ruminal parameters in lactating goats. Forty mid-lactation Murciano-Granadina goats were randomly allocated to four diets including (1) SBM (16.5% CP; CON); (2) untreated SM (USM; 16.5% CP). (3) formaldehyde-treated SM (FTSM; 16.5% CP), and (4) FTSM containing 14.5% CP (LPFT). FTSM goats had higher dry matter (DM) and nutrient intake than CON and LPFT, as observed for milk fat (P<0.001) and total solids (TS; P=0.001) yield. Milk fat content was higher with USM than LPFT (P<0.05). In general, the sum of milk saturated fatty acids (SFA) decreased, and milk unsaturated FA (UFA), monounsaturated FA (MUFA), polyunsaturated FA (PUFA), and long-chain FA (LCFA) increased by the inclusion of USM, and FTSM in the diet. Incorporation of FTSM in the diet decreased ruminal pH, ammonia nitrogen, and acetate molar proportion compared to CON and USM as observed with LPFT. Also, this inclusion increased total volatile FAs production and propionate proportion compared to CON and USM (P<0.001). In conclusion, substitution of SBM for FTSM in the diet of dairy goats can improve milk and milk component yield as well as health-promoting alterations in milk FAs profile. Furthermore, reducing dietary CP level along with FTSM inclusion in the diet may be considered as a proper tool in compensating the adverse effects of dietary CP deficiency and optimizing the productive performance of dairy goats utilizing lower amounts of nitrogen sources.
5 pages, It can be argued that public forums are a valuable and essential tool for Cooperative Extension professionals. This article narrates the innovative use of the public forum action steps outlined in Kahl’s (2016) “A Convener’s Guide to Hosting a Public Forum”. The primary objective was to address illegal dumping and littering concerns with the Extension professional's role to engage the community. The resulting “Backyard Composting Project” demonstrated that public forums are valuable in creatively engaging urban audiences. Ultimately the authors illustrate how a community concern can be addressed using innovative programming to reach what Extension considers to be non-traditional urban populations.

9 pages, Charismatic megafauna are arguably considered the primary attractor of ecotourists to sub-Saharan African protected areas. However, the lack of visitation data across the whole continent has thus far prevented the investigation of whether charismatic species are indeed a key attractor of ecotourists to protected areas. Social media data can now be used for this purpose. We mined data from Instagram, and used generalized linear models with site- and country-level deviations to explore which socio-economic, geographical and biological factors explain social media use in sub-Saharan African protected areas. We found that charismatic species richness did not explain social media usage. On the other hand, protected areas that were more accessible, had sparser vegetation, where human population density was higher, and that were located in wealthier countries, had higher social media use. Interestingly, protected areas with lower richness in non-charismatic species had more users. Overall, our results suggest that more factors than simply charismatic species might explain attractiveness of protected areas, and call for more in-depth content analysis of the posts. With African countries projected to develop further in the near-future, more social media data will become available, and could be used to inform protected area management and marketing.
22 pages., via online journal., Identifying and communicating uncertainty is core to effective environmental
assessment (EA). This study evaluates the extent to which uncertainties are considered
and addressed in Canadian EA practice. We reviewed the environmental protection
plans, follow-up programs, and panel reports (where applicable) of 12 EAs between
1995 and 2012. The types of uncertainties and levels of disclosure varied greatly.
When uncertainties were acknowledged, practitioners adopted five different
approaches to address them. However, uncertainties were never discussed or
addressed in depth. We found a lack of suitable terminology and consistency in how
uncertainties are disclosed, reflecting the need for explicit guidance, and we present
recommendations for improvement. Canadian Environmental Impact Statements are
not as transparent with respect to uncertainties as they should be, and uncertainties in
EA need to be better considered and communicated.

9 pages., Via online journal., This article reports on an exploratory study designed to measure community leaders’
attitudes toward scenes from working rural landscapes as elicited by photographs
paired with a semantic differential scale. Using this approach it is determined that
age, occupation, knowledge about farm structure, and community size are important
factors shaping the diverse attitudes held by community leaders in rural southern
Illinois. Findings suggest that the position and magnitude of attitude differences
between relevant social groups be examined prior to launching new rural development initiatives.
