      The Barnegat Bay-Little Egg Harbor Estuary is classified here as a highly eutrophic estuary based on application of NOAA’s National Estuarine Eutrophication Assessment model. Because it is shallow, poorly flushed, and ...
    • Bcl-xL regulates metabolic efficiency of neurons through interaction with the mitochondrial F1FO ATP synthase 

      Alavian, Kambiz N.; Li, Hongmei; Collis, Leon P.; Bonanni, Laura; Zeng, Lu; Sacchetti, Silvio; Lazrove, Emma; Nabili, Panah; Flaherty, Benjamin; Graham, Morven; Chen, Yingbei; Messerli, Shanta M.; Mariggio, Maria A.; Rahner, Christoph; McNay, Ewan; Shore, Gordon; Smith, Peter J. S.; Hardwick, J. Marie; Jonas, Elizabeth A. (2011-06)
      Anti-apoptotic BCL-2 family proteins such as Bcl-xL protect cells from death by sequestering apoptotic molecules, but also contribute to normal neuronal function. We find in hippocampal neurons that Bcl-xL enhances the ...
    • The behaviour and ecology of the zebrafish, Danio rerio 

      Spence, Rowena; Gerlach, Gabriele; Lawrence, Christian; Smith, Carl (2007-03-07)
      The zebrafish is an important model organism in developmental genetics, neurophysiology and biomedicine, but little is known about its natural ecology and behaviour. It is a small, shoaling cyprinid, native to the flood-plains ...
    • Benthic community metabolism in deep and shallow Arctic lakes during 13 years of whole–lake fertilization 

      Daniels, William C.; Kling, George W.; Giblin, Anne E. (2015-05)
      Benthic primary production and oxygen consumption are important components of lake biogeochemical cycling. We performed whole-lake nutrient manipulations in arctic Alaska to assess the controls of lake morphometry, ...
    • Better to light a candle than curse the darkness : illuminating spatial localization and temporal dynamics of rapid microbial growth in the rhizosphere 

      Herron, Patrick M.; Gage, Daniel J.; Pinedo, Catalina Arango; Haider, Zane K.; Cardon, Zoe G. (Frontiers Media, 2013-09-02)
      The rhizosphere is a hotbed of microbial activity in ecosystems, fueled by carbon compounds from plant roots. Basic questions about the location and dynamics of plant-spurred microbial growth in the rhizosphere are difficult ...
    • Beyond leaf color : comparing camera-based phenological metrics with leaf biochemical, biophysical, and spectral properties throughout the growing season of a temperate deciduous forest 

      Yang, Xi; Tang, Jianwu; Mustard, John F. (John Wiley & Sons, 2014-03-31)
      Plant phenology, a sensitive indicator of climate change, influences vegetation-atmosphere interactions by changing the carbon and water cycles from local to global scales. Camera-based phenological observations of the ...
    • Bidirectional incompatibility among divergent Wolbachia and incompatibility level differences among closely related Wolbachia in Nasonia 

      Bordenstein, Seth R.; Werren, John H. (2007-03-07)
      Most insect groups harbor obligate bacterial symbionts from the alphaproteobacterial genus Wolbachia. These bacteria alter insect reproduction in ways that enhance their cytoplasmic transmission. One of the most common ...
