Light response curve methodology and possible implications in the application of chlorophyll fluorescence to benthic diatoms (2006, methodology): “…productivity 64 using different methodologies, principally carbon uptake (radio-labeled 14 C), electron 65 transport rate (Chl a fluorescence) and oxygen evolution (oxygen electrodes) 66 (Flameling & Kromkamp 1998, Hartig et al. 1998, Barranguet and Kromkamp 2000, 67 Perkins et al. 2001, 2002).”
Coupled nitrification‐denitrification in autotrophic and heterotrophic estuarine sediments: On the influence of benthic microalgae (2003, background): “Photosynthesizing microalgae can contribute substantially to the carbon flow in sediments (Underwood and Kromkamp 1999; Middelburg et al. 2000; Perkins et al. 2001) via the release of photoassimilates in the form of carbohydrate (Smith and Underwood 2000) to the sediment environment.”
Spatiotemporal changes in microphytobenthos assemblages in a macrotidal flat (Bourgneuf Bay,France) 1 (2007, background): “At highest irradiance, motile cells move down into the sediments to avoid highlight-induced photodamage (Underwood and Kromkamp 1999, Perkins et al. 2001).”
LIGHT‐INDUCED RESPONSES OF OXYGEN PHOTOREDUCTION, REACTIVE OXYGEN SPECIES PRODUCTION AND SCAVENGING IN TWO DIATOM SPECIES 1 (2010, background): “MPB can also optimize photosynthetic performance partly due to finescale vertical migration by cells into the sediments to adjust their position in the sediment light and oxygen gradients (Perkins et al. 2001, Underwood et al. 2005, Waring et al. 2007).”
Photosynthetic activity, photoprotection and photoinhibition in intertidal microphytobenthos as studied in situ using variable chlorophyll fluorescence (2008, background): “However, only a few of these have simultaneously characterized the photophysiological and migratory responses of microphytobenthos to changing environmental conditions (Brotas et al., 2003; Perkins et al., 2001) and, to our knowledge, none has addressed quantitatively the functioning of photoprotect”
Influence of temperature on the relationship between oxygen- and fluorescence-based estimates of photosynthetic parameters in a marine benthic diatom (Cylindrotheca closterium) (2003, background): “…C-fixation or oxygen evolution and ETR is not always linear and this non-linearity is sometimes observed in microphytobenthos (Hartig et al. 1998, Barranguet & Kromkamp, 2000, Perkins et al. 2001) as well as in planktonic algae (Geel et al. 1997, Flameling & Kromkamp, 1998, Masojídek et al. 2001).”
Patterns in microphytobenthic primary productivity: Species‐specific variation in migratory rhythms and photosynthetic efficiency in mixed‐species biofilms (2005, background): “…estuarine sediments with a photic zone of only ;400 mm in depth (Consalvey 2002); limited periods of light exposure (Serôdio and Catarino 1999); and highly variable, and potentially stressful, temperatures and irradiances (Blanchard and Guarini 1996; Perkins et al. 2001; Underwood 2002).”
RELATIVE INCREASE OF DEOXY SUGARS DURING MICROBIAL DEGRADATION OF AN EXTRACELLULAR POLYSACCHARIDE RELEASED BY A TROPICAL FRESHWATER THALASSIOSIRA SP. (BACILLARIOPHYCEAE) 1 (2003, background): “Nevertheless, protection of the photosynthetic apparatus by an overflow mechanism has become more evident with the advancement of fluorescent techniques for measurements of photophysiological responses in algae (Smith and Underwood 2000, Perkins et al. 2001).”
Physiological versus behavioral photoprotection in intertidal epipelic and epipsammic benthic diatom communities (2011, background): “This is often referred to as behavioral photoprotection (Admiraal, 1984; Kromkamp et al., 1998; Perkins et al., 2001; Serôdio et al., 2006).”
Influence of Corophium volutator and Hydrobia ulvae on intertidal benthic diatom assemblages under different nutrient and temperature regimes (2002, background): “This length of time is considered optimal for achieving a stable value for F015 (Barranguet & Kromkamp 2000, Perkins et al. 2001).”
Biofilm polymers: relationship between carbohydrate biopolymers from estuarine mudflats and unialgal cultures of benthic diatoms (2005, background): “Estuarine diatoms produce different types of EPS in response to varying conditions (de Brouwer & Stal 2001, Perkins et al. 2001, Underwood et al. 2004) and the close relationship between diatom biomass and sediment carbohydrate fractions indicates that diatom exudates are an important source of…”
