Edible caterpillars are of vital importance to rural communities in developing countries providing high protein values and income. However, their ecology particularly seasonal fluctuations in their numbers is still poorly understood. With the ongoing climate change and increasing deforestation, their survival is a crucial issue.

Background: The most prevalent kind of diabetes that results from insulin resistance is type 2. Hyperglycemia, polyphagia, polyuria, and polydipsia are the traditional trifecta of symptoms associated with this illness. The purpose of this study was to ascertain the impact of petersianthus macrocarpus ethanolic leaf extract on the lipid profile and haematological markers of streptozotocin-induced type 2 diabetic wistar rats. Materials and methods: Five groups of rats were used: non-diabetic, diabetic, untreated, glibenclamide-treated, ethanolic extract-treated, and 100 mg/kg body weight-treated

Resumen
Wood is a biodegradable material. Decay resistance of wood is improved when the wood is chemically modified. The decayresistance of a chemically modified wood is improved as the modification stabilizes the cell wall polymers against enzyme attackdue to the blocking of accessible hydroxyl groups of the cell wall polymers which reduces the amount of water for hydrolysis. Theimproved durability of the modified wood as a result of reducing the amount of water molecules into the cell wall for hydrolysiswill depend on either bulking or percentage hydroxyl substitution (%OH).

Resumen
Understanding the dynamics of dominant tree species in tropical forests is important both for biodiversity and carbon-related issues. We focus on the Congo Basin (East of Kisangani) to investigate the respective roles of topographic/soil gradients and endogenous dynamics in shaping local variations in dominance. We used a dataset of 30 1-ha plots, in which all trees above 10 cm diameter at breast height (DBH) were censused. Soil samples were analyzed for standard pedologic variables and a digital elevation model permitted to infer topography and hydromorphy. We found that this forest is charac

Abstract Imbrasia epimethea is one of the most esteemed and popular caterpillar species for its remarkable organoleptic and nutritional values. Its consumption extends throughout the Kwilu province and nearly the entire Democratic Republic of the Congo, but its supply is very limited. The high anthropogenic pressure and the poor harvesting techniques employed by the population of Kwilu pose a major threat to the conservation of the species.
