Thoreau's experiment at Walden Pond reveals two potentially contradictory desires, one of which can be linked to agrarian reform, and the other to ecological knowledge. Thoreau conceived his Walden project in a cultural milieu in which agrarian reform was receiving incrasing attention, and the Walden experiments was, in important ways,...
Myxozoans are a group of diverse, spore-forming metazoan microparasites bound to aquatic environments. Sphaerospora dykovae (previously S. renicola) causes renal sphaerosporosis and acute swim bladder inflammation (SBI) in juvenile Cyprinus carpio carpio, in central Europe. A morphologically similar species with comparably low pathogenicity, S. angulata has been described from C....
With advancing computational resources, 3-D inversion techniques have become feasible in recent years and are now a more widely used tool for magnetotelluric (MT) data interpretation. Galvanic distortion caused by small-scale near-surface inhomogeneities remains an obstacle for 3-D MT inversion which so far has experienced little attention. If not considered...
At the submerged margins of the North Atlantic, andesitic to dacitic and basaltic volcanic rocks occur together. The silicic rocks were derived by processes requiring the presence of continental crust (crustal anatexis and/or contamination of mafic magmas) while the majority of the basaltic lavas had little or no contact with...
This translation consists of excerpts from a book on Jiao Juyin, who was a distinguished director of Chinese spoken drama. The selections translated here highlight Jiao's two principal theories: the Theory of Mental Images and "On Nationalizing Spoken Drama." The first represents his adaptation of the Stanislavsky system; the second...
Transcriptional studies in relation to fruit ripening generally aim to identify the transcriptional states associated
with physiological ripening stages and the transcriptional changes between stages within the ripening programme.
In non-climacteric fruits such as grape, all ripening-related genes involved in this programme have not been identified,
mainly due to the...
Palms are an important component of tropical ecosystems, living alongside dicotyledonous trees, even though they have a very different growth pattern and vascular system. As monocots, vessels in palms are located within vascular bundles and, without a vascular cambium that many dicotyledonous trees possess, palms cannot add additional vessels to...
Recent comparative studies across sex-changing animals have found that the relative size and age at sex change are strikingly invariant. In particular, 91%–97% of the variation in size at sex change across species can be explained by the simple rule that individuals change sex when they reach 72% of their...
