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 ...

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 (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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Aim of the study: To characterize wood anatomical traits of three Eucalyptus species that differ in wood density and ecological requirements, and to examine the relationships between some anatomical features, wood density, ...
