Interactions between host sex and seasonal changes shape the gut microbial communities of wild blue sheep (Pseudois nayaur)

Frontiers in Microbiology
The construction of gut microbial communities in wildlife is influenced by both environmental factors and host genetic background. However, the mechanisms through which these factors interact to shape microbial communities remain poorly understood.

Melatonin increases the chilling tolerance of chloroplast in cucumber seedlings by regulating photosynthetic electron flux and the ascorbate-glutathione cycle

Frontiers in Plant Science, 2016
The aim of the study was to monitor the effects of exogenous melatonin on cucumber (Cucumis sativus L.) chloroplasts and explore the mechanisms through which it mitigates chilling stress. Under chilling stress, chloroplast structure was seriously damaged

The dietary patterns of water deer recently rediscovered in Northeast China exhibit remarkable similarities to those observed in other regions

Scientific Reports
Climate change, human activities, and habitat fragmentation—or even loss—pose ongoing threats to the survival of wildlife. Understanding the dietary habits of endangered species is a critical component of their conservation.

Wide Area Voltage Protection

IET Generation, Transmission & Distribution, 2010
Two very promising wide-area voltage protection (V-WAP) solutions, able to face stability and security problems in the transmission grid, are presented. Both require real-time effective risk indicators whose timely computing is a crucial issue. The first method makes use of a voltage instability index based on real-time computing of the Thevenin ...
