Emerging opportunities and challenges in phenology : a review
(John Wiley & Sons, 2016-08-18)
Plant phenology research has gained increasing attention because of the sensitivity of phenology to climate change and its consequences for ecosystem function. Recent technological development has made it possible to gather ...
Prey capture by the cosmopolitan hydromedusae, Obelia spp., in the viscous regime
(John Wiley & Sons, 2016-08-29)
Obelia spp. are cnidarian hydromedusae with a cosmopolitan distribution but very little is known about their feeding. The small size of Obelia (bell diameter ∼ 1 mm, tentacle width ∼ 0.05 mm) suggests that feeding occurs ...
Regeneration of oral siphon pigment organs in the ascidian Ciona intestinalis
Ascidians have powerful capacities for regeneration but the underlying mechanisms are poorly understood. Here we examine oral siphon regeneration in the solitary ascidian Ciona intestinalis. Following amputation, the ...
Neuronal calcium sensor-1 enhancement of InsP3 receptor activity is inhibited by therapeutic levels of lithium
(American Society for Clinical Investigation, 2006-06)
Regulation and dysregulation of intracellular calcium (Ca2+) signaling via the inositol 1,4,5-trisphosphate receptor (InsP3R) has been linked to many cellular processes and pathological conditions. In the present study, ...
Correction to “Importance of carbon-nitrogen interactions and ozone on ecosystem hydrology during the 21st century”
(American Geophysical Union, 2009-08-22)
Distribution of postsynaptic density (PSD)-95 and Ca2+/calmodulin-dependent protein kinase II at the PSD
(Society for Neuroscience, 2003-12-03)
Postsynaptic densities (PSDs) contain proteins that regulate synaptic transmission. We determined the positions of calcium/calmodulin-dependent protein kinase II (CaMKII) and PSD-95 within the three-dimensional structure ...
Novel structures associated with presumed photoreceptors in the aboral sense organ of ctenophores
(University of Chicago, 2016-10)
It is rare nowadays to find something that nobody has seen before, especially without using a new methodology or looking in a new place. Using conventional differential interference contrast (DIC) microscopy, I describe ...
Analysis of isoform-specific tau aggregates suggests a common toxic mechanism involving similar pathological conformations and axonal transport inhibition
Misfolded tau proteins are characteristic of tauopathies, but the isoform composition of tau inclusions varies by tauopathy. Using aggregates of the longest tau isoform (containing 4 microtubule-binding repeats and 4-repeat ...
Composition and carbon dynamics of forests in northeastern North America in a future, warmer world
(NRC Research Press, 2009-02-13)
Increasing temperatures, precipitation extremes, and other anthropogenic influences (pollutant deposition, increasing carbon dioxide) will influence future forest composition and productivity in the northeastern United ...
Long-term warming alters carbohydrate degradation potential in temperate forest soils
(American Society for Microbiology, 2016-09-02)
As Earth's climate warms, soil carbon pools and the microbial communities that process them may change, altering the way in which carbon is recycled in soil. In this study, we used a combination of metagenomics and bacterial ...
