Effects of logging on the ecological strategy spectrum of a tropical montane rain forest

Ecological strategy is the various adaptation tactics of species to different living conditions, which can reflect their contrasting approaches to survival in varying habitats. The number and relative abundance of species in different types of ecological strategies actually forms an ecological strat...

The number and relative abundance of species in different types of ecological strategies actually forms an ecological strategy spectrum in a community. Logging is a widespread driver of forest degradation, severely influencing the composition of communities and the ecological strategy spectra in forest ecosystems. Understanding effects of logging on the ecological strategy composition of communities is vital to biodiversity conservation and efficient restoration of degraded forest ecosystems.
