Ten microsatellite markers were developed for the fungus Kirramyces gauchensis, which causes an important stem canker disease of Eucalyptus trees in plantations. Primers for 21 microsatellite regions were designed from cloned fragments. Fourteen of the primer pairs provided single amplicons and 10 of these were polymorphic for K. gauchensis. Allelic diversity ranged from 0.21 to 0.76 with a tot...

Traveler: Adrián Ares-University of Hawaii Objectives: The objective of this trip was to discuss P diagnostics and fertilization experiments for peach palm (Bactris gasipaes) with Costa Rica collaborators and to visit peach palm plantations in order to refine the research protocols for these experiments. The overall goals of this portion of the project are: 1. To determine advantages and disadv...
Recently, a rapid decline in the quality of Indian tea production has been observed due to the old age of the plantations, disease and pests infestations and frequent application of pesticides and insecticides. This paper shows an application of remote sensing and GIS technologies for monitoring tea plantations. We developed an approach for monitoring and assessing tea bush health using texture...

In this paper we study the Lyapunov stability and Hopf bifurcation in a biological system which models the biological control of parasites of orange plantations.

LONGHORN BEETLES (COLEOPTERA Cerambycidae) have been used to identify sites of high biological diversity and conservation value in cultivated landscapes, but were rarely studied in changing landscapes of humid tropics. This study was conducted in a region of southern Yunnan, China, which was dominated by natural rainforest until 30 years ago, but is successively transformed into commercial rubb...
Nitrogen (N) fertilization is necessary to sustain productivity in eucalypt plantations, but it can increase the risk of greenhouse gas emissions. However, the response of soil greenhouse gas emissions to N fertilization might be influenced by soil characteristics, which is of great significance for accurately assessing greenhouse gas budgets and scientific fertilization in plantations. We cond...
