We investigated color preference, seasonal abundance, spatial distribution and species composition of thrips in northern highbush blueberries, Vaccinium corymbosum L., in New Jersey (USA). White sticky traps were more attractive to thrips compared with yellow or blue traps. Thrips captures using white sticky traps showed that their flight activity begins 20e30 d after the onset of flowering, wi...

In the present tutorial we address a problem with a long history, which remains of great interest to date due to its many important applications: It concerns the existence and stability of periodic and quasiperiodic orbits in N degree of freedom Hamiltonian systems and their connection with discrete symmetries. Of primary importance in our study is what we call nonlinear normal modes (NNMs), i....

Three new species of the genus Neophyllobius Berlese, 1886 are described and illustrated from Iran: Neophyllobius edwardi sp. nov. and Neophyllobius seemani sp. nov. collected from soil under oak trees; and Neophyllobius dogani sp. nov. collected from soil under Astragalus bushes. A key to the species of Iran is provided.

During the last decades, large-scale land use changes took place in the Hailiutu River catchment, a semiarid area in northwest China. These changes had significant impacts on the water resources in the area. Insights into groundwater and surface water interactions and vegetationwater dependencies help to understand these impacts and formulate sustainable water resources management policies. In ...

Flume studies have been carried out to investigate flow structure for relatively low velocities and inundation for vegetation typical to floodplains and wetlands, such as grasses and bushes. Mean velocity profiles and turbulence characteristics from flume experiments on three different natural vegetal roughness types are reported. Two relatively new approaches for describing vertical velocity p...

Along with traditional and popular berry crops in private gardens, there are few common types decorative forms. The purpose of the research was to expand range ornamental shrubs landscaping large Metropolitan areas popularize knowledge about new or little-known bushes. As a result studies on value adaptation coefficient, studied shrub species were divided into three groups according degree pros...

We prove that the supercritical one-dimensional contact process survives in certain wedge-like space-time regions, and that when it survives it couples with the unrestricted contact process started from its upper invariant measure. As an application we show that a type of weak coexistence is possible in the nearest-neighbor “grass-bushes-trees” successional model introduced in [5].

Two new species of the genus Anoplocheylus Berlese, 1910 are described: Anoplocheylus marivaniensis sp. nov. collected from soil and rotten leaves under oak trees and Anoplocheylus qorvehiensis sp. nov. from soil under Astragalus sp. bushes in Kurdistan province, Iran. A key to females of all known species of Anoplocheylus is provided, based on original descriptions and other literature.
