Resumen
Abstract. Much of the variability in the surface ocean's carbon cycle can be attributed to the availability of sunlight, triggering surface heat flux and photosynthesis, which in turn regulate the biogeochemical cycling of carbon over a wide range of time scales. The critical processes of this carbon cycle regulation, occurring at time scales of a day or less, however, have undergone few investigations, most of which have been limited to time spans of several days to months. Optical methods have helped to infer short-term biological variability, but complementing investigations of the oceanic

Resumen
AbstractThe McMurdo Dry Valleys of Antarctica are a climate-sensitive ecosystem, where future projected climate warming will increase liquid water availability to release soil biology from physical limitations and alter ecosystem processes. For example, many studies have shown that CO2 flux, an important aspect of the carbon cycle, is controlled by temperature and moisture, which often overwhelm biotic contributions in desert ecosystems. However, these studies used either single-point measurements during peak times of biological activity or diel cycles at individual locations. Here, we present

Resumen
Inspired by an analogy to AM radio signals, amplitude modulation (AM) is proposed here as a useful view of nonstationary environmental periodicities, and applied to hydrologic and air quality datasets. Both example time series considered exhibit seasonally evolving diel cycles, with large (small) daily cycle amplitudes in summer (winter). The carrier wave is taken to be a sinusoidal daily cycle; this is multiplied by an information signal consisting of a sinusoidal annual cycle, forming an envelope to the diel variations. Our results suggest that amplitude modulation may offer a novel, compact

Resumen
The cycling of organic carbon is fundamental to aquatic ecosystems, reflecting processes that extend from terrestrial watersheds to fish. Here, we use embedded fluorescence sensors that sample at high frequency to investigate the daily dynamics of a proxy for the major pool of organic carbon (chromophoric dissolved organic matter, CDOM) in a clear-water Wisconsin lake (∼3 mg C·L−1). We compare the diel CDOM cycle in this lake with cycles observed previously in two dark-water lakes (10 to 20 mg C·L−1). Despite differences in DOM quality and quantity, diel fluorescence cycles were evident in the

Abstract. Fixation of organic carbon by phytoplankton is the foundation of nearly all open-ocean ecosystems and a critical part of the global carbon cycle. But the quantification and validation of ocean primary productivity at large scale remains a major challenge due to limited coverage of ship-based measurements and the difficulty of validating diverse measurement techniques. Accurate primary productivity measurements from autonomous platforms would be highly desirable due to much greater potential coverage. In pursuit of this goal we estimate gross primary productivity over 2 months in the

As an adaptation to the daily light–dark (diel) cycle, cyanobacteria exhibit diurnal rhythms of gene expression and cell cycle. The light–dark cycle also affects the life cycle of viruses (cyanophages) that infect the unicellular picocyanobacteriaProchlorococcusandSynechococcus, which are the major primary producers in the oceans. For example, the adsorption of some cyanophages to the host cells depends on light, and the burst sizes of cyanophages are positively correlated to the length of light exposure during infection.

Shrinking alpine glaciers alter the geochemistry of sensitive mountain streams by exposing reactive freshly-weathered bedrock and releasing decades of atmospherically-deposited trace elements from glacier ice.

Resumen
Titanium forged components have been widely used in aircraft engine industry because of their superior specific strength to weight ratio at high temperature. Turbine disk is one of the most demanding forging parts. The flow stress of titanium alloy Ti-6Al-4V is strongly dependent on temperature and strain rate during hot forging. The cooling rate can be designed to manage the temperature profile of dies by distinct spray setup. The workpiece loses heat to die by contact when getting heat up for deformation. The study aims to assess the influence of the discrete cooling rate and interfacial con

Resumen
Abstract. In copper extrusion, the dies are continuously subjected to high thermo-mechanical stress. This results in elastic and plastic die deformation as well as extensive wear. To estimate the strain of possible hard phase surface modifications during service, knowledge of the deformation behavior of the extrusion dies is required. Therefore, the plastic deformation of dies made of four different tool materials was investigated in the present study. The applied tool materials were hot-work tool steel 1.2367, special hot-work tool steel CS1, nickel-based alloy 2.4668 (Alloy 718) and cobalt-b

Resumen
Animal-associated microbiomes are critical to the well-being and proper functioning of the animal host, but only limited studies have examined in-sect microbiomes across different developmental stages. These studies revealed large shifts in microbiome communities, often because of significant shifts in diet during insects’ life cycle. Establishing insect colonies as model laboratory organisms and understanding how to properly feed and care for animals with complex and dynamic life cycles requires improved data. This study examined laboratory raised green June beetles (Cotinis nitida) captured

Resumen
This first part of an in-depth treatment of Austrian rust fungi (Pucciniales, formerly Uredinales) contains all genera except Puccinia s.l. and Uromyces. The rust species included here belong to the families Coleosporiaceae, Melampsoraceae, Milesinaceae, Pucciniastraceae (all four in suborder Melampsorineae), as well as Gymnosporangiaceae, Ochropsoraceae, Phragmidiaceae, Tranzscheliaceae, and some taxa of uncertain position. The introductory part consists of four chapters. Instead of a glossary, a short ‘Introduction to the rust fungi’ and their terminology is presented. It is based on the lif

Resumen
The reproduction cycle and the host specificity of the freshwater pearl mussel, Hyriopsis (Limnoscapha) myersiana were studies from April 1990 to May 1991. Marsupia were found already in early November but, the peak occurred between December and January. The glochidia will emerge from late November till early March. In the laboratory, mussel took less than 24 hours to release all the glochidia. The experiment on host specificity of the glochidia on the fry of 11 species of fish was carried out, using 4 levels of glochidium concentration. The mortality of the fish after infection was plotted ag

Resumen
The major bottlenecks in rearing the highly priced gastropod abalone (Haliotis spp.) are the slow growth rate and the high mortality during the first 8 to 12 weeks following metamorphosis and settling. The most likely reason flor these problems is related to nutritional deficiencies in the diatom diet on which the post larvae (PL) feed almost exclusively in captivity. Higher survival and improved growth rate will reduce the considerable expense of hatchery-nursery resisdence time and thereflore the production costs.

Research objectives were: 1) To study the effect of diet energy density, level of exercise, thermal conditions and reproductive state on cardiovascular function as it relates to oxygen (O2) mobilization. 2) To validate the use of heart rate (HR) to predict energy expenditure (EE) of ruminants, by measuring and calculating the energy balance components at different productive and reproductive states. 3) To validate the use of HR to identify changes in the metabolizable energy (ME) and ME intake (MEI) of grazing ruminants.
