Contributions of photosynthetic organs to the seed yield of hybrid rice: The effects of gibberellin application examined by carbon isotope technology
(Zheng et al., 2018-12-01)Changes in the structure and quality of a hybrid combination population have been observed after the application of gibberellins. Such changes would affect the accumulation and distribution of photosynthetic products, which ... -
Vegetation indices do not capture forest cover variation in Upland Siberian Larch Forests
(MDPI AG, Basel, Switzerland, 2018-10-25)Boreal forests are changing in response to climate, with potentially important feedbacks to regional and global climate through altered carbon cycle and albedo dynamics. These feedback processes will be affected by vegetation ... -
The Bermuda Triangle : the pragmatics, policies, and principles for data sharing in the history of the Human Genome Project
(Springer, 2018-11-02)The Bermuda Principles for DNA sequence data sharing are an enduring legacy of the Human Genome Project (HGP). They were adopted by the HGP at a strategy meeting in Bermuda in February of 1996 and implemented in formal ... -
Two forms of electrical transmission between neurons
(Frontiers Media, 2018-11-21)Electrical signaling is a cardinal feature of the nervous system and endows it with the capability of quickly reacting to changes in the environment. Although synaptic communication between nerve cells is perceived to be ... -
Stable isotopic evidence of nitrogen sources and C4 metabolism driving the world’s largest macroalgal green tides in the Yellow Sea
(Nature Publishing Group, 2018-11-28)During recent years, rapid seasonal growth of macroalgae covered extensive areas within the Yellow Sea, developing the world’s most spatially extensive “green tide”. The remarkably fast accumulation of macroalgal biomass ... -
Environmental controls, emergent scaling, and predictions of greenhouse gas (GHG) fluxes in coastal salt marshes
(John Wiley & Sons, 2018-07-28)Coastal salt marshes play an important role in mitigating global warming by removing atmospheric carbon at a high rate. We investigated the environmental controls and emergent scaling of major greenhouse gas (GHG) fluxes ... -
Potential role of the anterior lateral line in sound localization in toadfish (Opsanus tau)
(Company of Biologists, 2018-11-26)Male oyster toadfish (Opsanus tau) acoustically attract females to nesting sites using a boatwhistle call. The rapid speed of sound underwater combined with the close proximity of the otolithic organs makes inner ear ... -
Existing climate change will lead to pronounced shifts in the diversity of soil prokaryotes
(American Society for Microbiology, 2018-10-23)Soil bacteria are key to ecosystem function and maintenance of soil fertility. Leveraging associations of current geographic distributions of bacteria with historic climate, we predict that soil bacterial diversity will ... -
Using noble gases to compare parameterizations of air‐water gas exchange and to constrain oxygen losses by ebullition in a shallow aquatic environment
(John Wiley & Sons, 2018-09-07)Accurate determination of air‐water gas exchange fluxes is critically important for calculating ecosystem metabolism rates from dissolved oxygen in shallow aquatic environments. We present a unique data set of the noble ... -
Discontinuities in soil strength contribute to destabilization of nutrient‐enriched creeks
(Ecological Society of America, 2018-08-20)In a whole‐ecosystem, nutrient addition experiment in the Plum Island Sound Estuary (Massachusetts), we tested the effects of nitrogen enrichment on the carbon and nitrogen contents, respiration, and strength of marsh ... -
Spartina alterniflora δ15N as an indicator of estuarine nitrogen load and sources in Cape Cod estuaries
(2018-04)δ15N values of coastal biota have been used as indicators of land-derived N-loads and sources to estuarine systems and should respond predictably to differences in nitrogen and be sensitive to changes in nitrogen, preferably ... -
Seasonal patterns of canopy photosynthesis captured by remotely sensed sun-induced fluorescence and vegetation indexes in mid-to-high latitude forests : a cross-platform comparison
(2018-06)Characterized by the noticeable seasonal patterns of photosynthesis, mid-to-high latitude forests are sensitive to climate change and crucial for understanding the global carbon cycle. To monitor the seasonal cycle of the ... -
Light control of G protein signaling pathways by a novel photopigment
(Public Library of Science, 2018-10-01)Channelopsins and photo-regulated ion channels make it possible to use light to control electrical activity of cells. This powerful approach has lead to a veritable explosion of applications, though it is limited to changing ... -
Optimizing resource use efficiencies in the food-energy-water nexus for sustainable agriculture : from conceptual model to decision support system
(2018-04)Increased natural and anthropogenic stresses have threatened the Earth’s ability to meet growing human demands of food, energy and water (FEW) in a sustainable way. Although much progress has been made in the provision of ... -
Using maximum entropy production to describe microbial biogeochemistry over time and space in a meromictic pond
(Frontiers Media, 2018-10-01)Determining how microbial communities organize and function at the ecosystem level is essential to understanding and predicting how they will respond to environmental change. Mathematical models can be used to describe ... -
Sparsened neuronal activity in an optogenetically activated olfactory glomerulus
(Nature Publishing Group, 2018-10-08)Glomeruli are the functional units of olfactory information processing but little remains known about their individual unit function. This is due to their widespread activation by odor stimuli. We expressed channelrhodopsin-2 ... -
Wheat rhizosphere harbors a less complex and more stable microbial co-occurrence pattern than bulk soil
(2018-07-25)The rhizosphere harbors complex microbial communities, whose dynamic associations are considered critical for plant growth and health but remain poorly understood. We constructed co-occurrence networks for archaeal, ... -
Description and evaluation of the MIT Earth System Model (MESM)
(John Wiley & Sons, 2018-08-15)The Massachusetts Institute of Technology Integrated Global System Model (IGSM) is designed for analyzing the global environmental changes that may result from anthropogenic causes, quantifying the uncertainties associated ... -
Multisensory and motor representations in rat oral somatosensory cortex
(Nature Publishing Group, 2018-09-10)In mammals, a complex array of oral sensors assess the taste, temperature and haptic properties of food. Although the representation of taste has been extensively studied in the gustatory cortex, it is unclear how the ... -
Mapping birefringence in three dimensions using polarized light field microscopy : the case of the juvenile clamshell
