Genotypic Differences among Argentinean Maize Hybrids in Yield Response to Stand Density
(Amer Soc Agronomy, 2014-10)
Maize (Zea mays L.) stand density selection is an important management practice because yield is maximized at a particularoptimum value. Optimum stand density (OSD) varies across environments, and many have argued that ...
Calculation of the statistical properties in intermittency using the natural invariant density
(Multidisciplinary Digital Publishing Institute, 2021-06)
We use the natural invariant density of the map and the Perron–Frobenius operator to analytically evaluate the statistical properties for chaotic intermittency. This study can be understood as an improvement of the previous ...
Maize stand density yield response of parental inbred lines and derived hybrids
(Crop Science Society of America, 2017-01)
Maize (Zea mays L.) grain yield has a parabolic response to stand density changes, creating an optimum stand density that maximizes yield. Argentinean commercial hybrids differ in their optimum stand density when grown at ...
Impacts of honeybee density on crop yield: A meta-analysis
(Wiley Blackwell Publishing, Inc, 2019-02-03)
1. There is increasing recognition that pollination deficits are limiting crop yields world-wide. However, management strategies for optimal insect pollination are still unclear for most crops. Current management focuses ...
Experimental field test of spatial variation in rodent predation of nuts relative to distance and seed density
The spatial context in which seed predation occurs may modify the spatial structure of recruitment generated by seed dispersal. The Janzen-Connell (J-C) model predicts that granivores will exert greater pressure on ...
Broad snouted caiman (Caiman latirostris) growth under different rearing densities
(Elsevier Science, 2008-04)
The effect of density on growth in body mass (BM) and total length (TL) of Caiman latirostris hatchlings raised in small pens (area 0.36 m2), for 3 months, was investigated. Twelve animals from each of three clutches were ...
Construction of a silvicultural scheme for Nothofagus dombeyi using potential available area, maximum density index and diameter growth variation according to densityConstrucción de un esquema silvícola para Nothofagus dombeyi, usando área potencial aprovechable, índice de máxima densidad y variación del crecimiento diametral según densidad

Density-dependent changes in the distribution of Southern Right Whales (Eubalaena australis) in the breeding ground Peninsula Valdés
Background: The Southern Right Whale (Eubalaena australis) population of the South–western Atlantic Ocean is recovering. In the breeding ground of Peninsula Valdés, as a consequence of the population growth, expansion to ...
Strength and nature of hydrogen bonding interactions in mono- and di-hydrated formamide complexes
(American Chemical Society, 2011-04)
In this work, mono- and di-hydrated complexes of the formamide were studied. The calculations were performed at the MP2/6-311++G(d,p) level of approximation. The atoms in molecules theory (AIM), based on the topological ...
Incorporating dynamic correlation into the variational determination method of the second-order reduced density matrix in the doubly occupied configuration interaction space
(John Wiley & Sons Inc, 2020-04)
The variational determination of the second-order reduced density matrices arising from N-electron doubly occupied configuration interaction wave functions has recently been proposed as a method to describe systems possessing ...
