We present the first self-consistent simulations of the coupled spin-shape evolution of small gravitational aggregates under the influence of the YORP effect. Because of YORP's sensitivity to surface ...
During the course of normal DNA replication, replication forks are constantly encountering "housekeeping" types of routine damage to the DNA template that may cause the forks to stall or collapse. One...
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...
To explore how gradients in nutrient availability influence the stoichiometry of freshwater autotrophs, we sampled algal and submerged vascular plant tissues, as well as water for C : N : P ratios in...
Spring bloom composition in the Baltic Sea, a partially ice-covered brackish coastal waterbody, is shaped by winter–spring weather conditions affecting the relative dominance of diatoms and a heteroge...
Arsenic and phosphorus are biochemically very similar, and hence arsenate (As5+) is toxic by interfering with the energy metabolism, in particular during P limitation. However, many phytoplankton deto...
The trace metals aluminum (Al) and manganese (Mn) were studied in the Weddell Sea in March 2008.Concentrations of dissolved Al ([Al]) were slightly elevated (0.23–0.35 nmol L21) in the surface layer c...
I show that the growth ofTrichodesmium, the primary diazotrophic phytoplankton in tropical and subtropical oceans, can be limited by Ni availability in both trace metal–defined culture media and natur...
Karenia brevis blooms impair human health, marine ecosystems, and coastal economies in the Gulf of Mexico via their production of carbon-based neurotoxins (brevetoxins), which contain no nitrogen (N)...
We present data on eicosapentaenoic acid (EPA)-limited growth responses ofDaphnia magnaunder different temperatures and different dietary cholesterol availabilities to assess how EPA growth saturation...
Exposing the coral Stylophora pistillata to seawater depleted in available iron by complexation with the strong chelator desferrioxamine B reduces the photosynthetic efficiency and alters the pigment...
The relationship between phosphatase activity and the element limiting microbial activity (carbon [C], nitrogen [N], or phosphorus [P]) was studied experimentally in sediment from four stations in th...
Despite their high abundance, secondary production, and known reliance on detrital material, the role of chironomids (Diptera) in fine particulate organic matter (FPOM) dynamics has not been well quan...
Controversy exists about the historic shift of primary producer community structure (PPCS) in Lake Apopka,a shallow, 125-km2lake in central Florida, U.S.A. The controversial questions are: was a lake-...
Molybdenum (Mo) is essential for the biological assimilation of inorganic nitrogen (N). We compared Mo requirements for N2 -fixation in two species of filamentous heterocystous cyanobacteria (HC) to...
