Site Characteristics and Plant Invasion: Light Limitation of Invasive Establishment and Impacts of Elaeagnus Umbellata on Soil Nitrogen Availability and Co-occurring Species
soil nitrogen invasion facilitation
2015/1/6
Invasive species have become an increasing threat to many habitats worldwide. This research addressed the questions of whether several invasive woody plants can germinate, survive and grow in light le...
Modulation of Nhlh2 expression by energy availability leads to downstream effects on body weight regulation
The hypothalamus transcription factors nerve energy hormone neurons arcuate nucleus neurons
2014/12/11
Mice with a deletion of the hypothalamic basic helix-loop-helix transcription factor Nhlh2 (N2KO) display adult onset obesity, implicating Nhlh2 in the neuronal circuits regulating energy availability...
Energy availability signals and the prohormone convertase 1 gene are regulated by Nhlh2
Gene regulation signals transcription factors leptin thalamus arcuate nucleus neurons
2014/12/11
Body weight is controlled by gene regulation through the activation of signal transduction pathways which ultimately regulate transcription factors and their gene targets. Fluctuating leptin levels re...
