People and Nature, EarlyView.Abstract The town of Gamba in southwest Gabon represents an exceptional example of how the development of an extractive industry (in this case oil production) may impact wild meat consumption in an area of global importance for biodiversity. Studies in the 1990s identified an active wild meat trade; however, no studies have been undertaken since, and ...

Erosion Resistance Enhancement in Epoxy Composites by Recycled Rubber: Effect of Rubber Type
Polymer Engineering &Science, EarlyView.Erosion resistance enhancement in epoxy composites by recycled rubber. ABSTRACT Epoxy‐based materials have low erosion resistance due to their brittle nature, and toughness modification stands out for enhancing it. At this stage, the use of waste rubber as a reinforcement component in the composite system is of interest due to its role in providing ...

Permafrost and Periglacial Processes, EarlyView.ABSTRACT Due to its subsurface nature, permafrost cannot be directly observed with the naked eye or optical remote sensing. Consequently, accurately describing its distribution and thermal state is challenging. This is especially true in vast, remote environments, where obtaining comprehensive field data is demanding or improbable.
