Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures

High Voltage, EarlyView.
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

Hummingbird interaction niche packing is influenced by species richness and resource availability in the southern tropical Andes

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Niche partitioning is often considered an important mechanism promoting species co‐occurrence in species‐rich communities. As species richness increases, niche partitioning may lead to different niche structures, including increased packing of species niches when the ...
