Short‐term impacts of selective logging on forest elephants
This study assesses the impact of selective logging on forest elephants (Loxodonta cyclotis) in Gabon. Using camera traps and dung surveys, we found no negative effects on their presence, abundance, or activity. The results suggest that responsibly managed timber concessions can support forest elephant conservation.

Mass-transport resistances of acid and alkaline ionomer layers: A microelectrode study part 1 - Microelectrode development [PDF]
The use of microelectrodes to study localized mass-transport phenomena in fuel-cell catalyst layers is an increasingly valuable tool. However, existing microelectrode cells have been used in static, equilibrated environment modes with poorly controlled ...
