Our findings provide practical guidance for agroforestry management by demonstrating that intercropping with selected species can mitigate damage from leaf‐cutter ants in cacao agroforests. At the landscape scale, high tree cover was associated with low herbivory rates, emphasising the need to maintain or restore forested habitats.

Complex relationship between soil fungi and conservation value assessments in boreal forests
Abstract Large‐scale industrial forestry is a threat to biodiversity and imposes long‐lasting changes to many forested biomes. Preserving forests as reserves is an important component of the strategy for safeguarding forest biodiversity. Yet, the selection of forests of high biodiversity value is usually based on proxies (i.e., subsets of aboveground ...

Abstract This essay explores two types of population policies common in Arab countries: pro‐natalist policies, aimed at encouraging higher birth rates, and anti‐natalist policies, aimed at reducing birth rates. Determining their practical impact is often challenging due to the lack of control or comparison groups. However, historical policy patterns in

Land use legacies affect early tropical forest succession in Mexico
Land‐use practices have a strong effect on forest recovery. The implementation of high‐intensity land management practices, specifically the use of machinery, had the highest impact on early forest succession. When machinery was not used, the frequency of land‐use practices, particularly weeding frequency, is the main factor influencing tree cover and ...

Fertilidad del suelo y calidad nutricional de estacas de yuca (Manihot esculenta Crantz)
A study was conducted on the changes in nutritional content of cassava stems as a result of different soil fertilization levels, and on the effect of the stakes obtained from these stems on the subsequent crop. Results showed that the mother plants had different height and vigor depending on the 9 different nutritional levels of fertilizer application ...
