Assessment Of Seasonal Variations In Forage Quality In Saanane Island National Park, Mwanza, Tanzania, George M. Sangu, Cuthbert L. Nahonyo

Tanzania Journal of Science

Seasonal variations in proteins, vitamin A, vitamin C, carbohydrates and minerals (Ca, Fe, Na, K and P) for seven most grazed and four most browsed plant species were assessed using laboratory analysis to determine what nutrient resources were available to grazers and browsers inhabiting the Saanane Island. The results indicated great seasonal variations in proteins, vitamin A, vitamin C and carbohydrates which were statistically significant with P < 0.01, F 3.444 at DF 5. Similarly, the minerals (Ca, Fe, Na, K and P) showed greater seasonal variations with K and P being higher during wet season, while Na and Fe were higher in dry season. The levels of proteins, vitamins, fibres and minerals were well above daily dietary requirements for grazers and browsers. These results suggested that both grazers and browsers were benefiting from seasonal differences in terms of available resources at disposal as animal health is regulated by levels of proteins and vitamins available in grazing and browsing materials.  Keywords: Forage Quality, Minerals, Protein Saanane, Seasonality, Vitamin

Thinking In The Global South — Reflections On Anti-Vaxxers As An Instance Of Global Alterity, Raul Pertierra

Social Transformations Journal of the Global South

Excerpt: The COVID-19 pandemic has brought to light several features of the present state of globality. In many countries, objections against vaccination have attracted media prominence. Although reasons for this resistance may differ from one country to another, there seems to be a common thread linking them globally. This paper examines this thread and explores its relationship to conditions underlying modernity. As some have argued (e.g., Latour 2014, Luhmann 1998), modernity is not an explanatory concept but a category that allows us to label a complex reality, which includes internal contradictions (e.g., a society of universal levelling whose mechanism effaces …

The Illegally Traded Elephant In The Room: Species Terrorism & Combating Illegal Wildlife Trade, Áine Dillon

Pace International Law Review

The illegal wildlife trade has been a dilemma for decades

and remains prevalent globally – international intervention is

required now. While most countries participate in the Convention

on International Trade in Endangered Species of Wild

Fauna and Flora (“CITES”), not all countries have the same approaches

to combating the illegal wildlife trade. Unique approaches

can be beneficial because each illegally traded species

requires a different response, and countries with limited resources

can also participate. However, the lack of a unified response

hinders the global fight against the illegal wildlife trade.

While traditional methods to combat crime, such as passing

laws, …
