Langridge, R. M.; Villamor, P.; Litchfield, N. J.; Page, M.; Ries, W.; Ansell, I. A.; McNamara, David D.; Martin Gonzalez, F. (GNS Science, 2013)GNS Science has undertaken a field study to investigate the possibility of active secondary faulting in the vicinity of the proposed A7 dam site on the Makaroro River, central Hawke’s Bay. The A7 site is located c. 750 ... -
An assessment of RNA content in Prymnesium parvum, Prymnesium polylepis, cf. Chattonella sp. and Karlodinium veneficum under varying environmental conditions for calibrating an RNA microarray for species detection
McCoy, Gary R.; Touzet, Nicolas; Fleming, Gerard T.; Raine, Robin (Wiley, 2014-02-03)Traditional methods of identification and enumeration can be somewhat ambiguous when identifying phytoplankton that requires electron microscopic examination to verify specific morphological features. Members of the genus ... -
Beyond the green: understanding the evolutionary puzzle of plant and algal cell walls
Popper, Zoë A.; Tuohy, Maria G. (American Society of Plant Biologists, 2010-04-26)Niklas (2000) defined plants as “photosynthetic eukaryotes,” thereby including brown, red, and green macroalgae and microalgae. These groups share several features, including the presence of a complex, dynamic, and ... -
Bioinformatic identification and analysis of extensins in the plant kingdom
Liu, Xiao; Wolfe, Richard; Welch, Lonnie R.; Domozych, David S.; Popper, Zoë A.; Showalter, Allan M. (Public Library of Science, 2016-02-26)Extensins (EXTs) are a family of plant cell wall hydroxyproline-rich glycoproteins (HRGPs) that are implicated to play important roles in plant growth, development, and defense. Structurally, EXTs are characterized by the ... -
Bioreactor scalability: laboratory-scale bioreactor design influences performance, ecology, and community physiology in expanded granular sludge bed bioreactors
Connelly, Stephanie; Shin, Seung Gu; Dillon, Robert J.; Ijaz, Umer Zeeshan; Quince, Christopher; Sloan, William; Collins, Gavin (Frontiers Media, 2017)Studies investigating the feasibility of new, or improved, biotechnologies, such as wastewater treatment digesters, inevitably start with laboratory-scale trials. However, it is rarely determined whether laboratory-scale ... -
Bordetella pertussis expresses a functional type III secretion system that subverts protective innate and adaptive immune responses
Boyd, Aoife (American Society for Microbiology, 2008-01)Certain bacteria use a type III secretion system (TTSS) to deliver effector proteins that interfere with cell function into host cells. While transcription of genes encoding TTSS components has been demonstrated, studies ... -
Bumblebee colony development following chronic exposure to field-realistic levels of the neonicotinoid pesticide thiamethoxam under laboratory conditions
Stanley, Dara A.; Raine, Nigel E. (Nature Publishing Group, 2017-08-20)Neonicotinoid pesticides are used in agriculture to reduce damage from crop pests. However, beneficial insects such as bees can come into contact with these pesticides when foraging in treated areas, with potential ... -
Bumblebee learning and memory is impaired by chronic exposure to a neonicotinoid pesticide.
Stanley, Dara A.; Smith, Karen E.; Raine, Nigel E. (Nature Publishing Group, 2015-11-16)Bumblebees are exposed to pesticides applied for crop protection while foraging on treated plants, with increasing evidence suggesting that this sublethal exposure has implications for pollinator declines. The challenges ... -
Calcite sealing in a fractured geothermal reservoir: Insights from combined EBSD and chemistry mapping
McNamara, David D.; Lister, Aaron; Prior, Dave J. (Elsevier, 2016-05-10)Fractures play an important role as fluid flow pathways in geothermal resources hosted in indurated greywacke basement of the Taupo Volcanic Zone, New Zealand, including the Kawerau Geothermal Field. Over time, the ... -
Cell wall evolution and diversity
Fangel, Jonatan U.; Ulvskov, Peter; Knox, J. P.; Mikkelsen, Maria Dalgaard; Harholt, Jesper; Popper, Zoë A.; Willats, William G. T. (Frontiers Media, 2012-07-06)Plant cell walls display a considerable degree of diversity in their compositions and molecular architectures. In some cases the functional significance of a particular cell wall type appears to be easy to discern: secondary ... -
The cell walls of pteridophytes and other green plants - a review
Popper, Zoë A. (British Pteridological Society, 2006-12-22)The cell wall is one of the defining characteristics of plants and is a fundamental component in normal growth and development. Cell wall composition is a potentially valuable source of phylogenetic information as notable ... -
Ceratopteris richardii (C-Fern): a model for investigating adaptive modification of vascular plant cell walls
Leroux, Olivier; Eeckhout, Sharon; Viane, Ronald L. L.; Popper, Zoë A. (Frontiers Media, 2013-09-23)Plant cell walls are essential for most aspects of plant growth, development, and survival, including cell division, expansive cell growth, cell-cell communication, biomechanical properties, and stress responses. Therefore, ... -
Charophytes: evolutionary giants and emerging model organisms
Domozych, David S.; Popper, Zoë A.; Sørensen, Iben (Frontiers Media, 2016-10-10)Charophytes are the group of green algae whose ancestral lineage gave rise to land plants in what resulted in a profoundly transformative event in the natural history of the planet. Extant charophytes exhibit many features ... -
