    • Glycinergic feedback enhances synaptic gain in the distal retina 

      Jiang, Zheng; Yang, Jinnan; Purpura, Lauren A.; Liu, Yufei; Ripps, Harris; Shen, Wen (2013-09)
      Glycine input originates with interplexiform cells, a group of neurons situated within the inner retina that transmit signals centrifugally to the distal retina. The effect on visual function of this novel mechanism is ...
    • Going beyond the green : senesced vegetation material predicts basal area and biomass in remote sensing of tree cover conditions in an African tropical dry forest (miombo woodland) landscape 

      Mayes, Marc; Mustard, John F.; Melillo, Jerry M.; Neill, Christopher; Nyadzi, Gerson (IOP Science, 2017-08-08)
      In sub-Saharan Africa (SSA), tropical dry forests and savannas cover over 2.5 million km2 and support livelihoods for millions in fast-growing nations. Intensifying land use pressures have driven rapid changes in tree cover ...
