Megafauna moves nutrients uphill
Large animals have a disproportionate capacity to transport nutrients along gradients and against water flow directions, making them more available to ecosystems and ultimately saving them from disappearing in sea floor sediments. Megafauna extinctions have reduced this capacity dramatically, while humans and their livestock aren’t stepping in to restore this important ecosystem service.
متن کاملDetailed Analysis of Uphill Moves in Temperature Parallel Simulated Annealing and Enhancement of Exchange Probabilities
This paper demonstrates that the probability of the occurrence of uphill moves in temperature parallel simulated annealing is so small that the effects of parallelization might be lost when the number of processing nodes is small. A modification in the probability of solution exchange between the processes is one tactic to recover the parallelization effects. This method is evaluated by a trave...
متن کاملUphill/downhill nystagmus
Differential diagnosis between peripheral and central spontaneous nystagmus can be difficult to classify (as peripheral or central) even on the basis of criteria recommended in the recent literature. The aim of this paper is to use the combination of spontaneous nystagmus and ocular tilt reaction to determine the site of origin of the disease that causes nystagmus. We propose to classify the ny...
متن کاملUphill or Downhill
Companies know the amount of profit they make, but may not know whether they are operating on the uphill side or downhill side of the profit function with respect to each marketing investment variable. We first identify the risks of an uphill-located firm acting as if it were a downhill-located firm. Then, we develop a diagnostic tool to infer a company’s type based on its location on the profi...
