Response to Comments on “Changes in Climatic Water Balance Drive Downhill Shifts inPlantSpecies’OptimumElevations”
We recently reported that changes in climatic water balance across much of the state of California have led to downhill shifts in plant species’ distributions (1). Wolf and Anderegg (2), Hijmans (3), and Stephenson and Das (4) contend that our analysis was flawed.We address their comments here. Wolf and Anderegg (2) state that our results are narrowly applicable because of the limited number of...
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...
متن کاملDownhill domination in graphs
A path π = (v1, v2, . . . , vk+1) in a graph G = (V,E) is a downhill path if for every i, 1 ≤ i ≤ k, deg(vi) ≥ deg(vi+1), where deg(vi) denotes the degree of vertex vi ∈ V. The downhill domination number equals the minimum cardinality of a set S ⊆ V having the property that every vertex v ∈ V lies on a downhill path originating from some vertex in S. We investigate downhill domination numbers o...
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 کاملRan’s downhill slide during mitosis
Ran’s downhill slide during mitosis H asegawa et al. clarify the role of RanGTP in the formation of the mitotic spindle. Because RanGTP is prevalent in the cell, its job during spindle assembly has been difficult to nail down. One possibility is that RanGTP promotes construction of the spindle by liberating spindle assembly factors from the importins that carry them. Previous studies of Xenopus...
