Leucaena leucocephala is an important agroforestry species pan-tropically, but relatively little is known of the forage production potential of other species in the genus. The agronomic potential of 116 accessions, represent ing the 28 species and subspecies of the Leucaena genus and several arti...

Our aim in this study was to identify the economically optimal level of use of resources for a grazing system in tropical Australia and to compare it with the biological optimum. Grazing management trials were conducted in the Ord River irrigation area of north-western Australia. Biologists at th...

A breeding program to select low-mimosine lines of leucaena has been in progress since 1970. Selections were evaluated in two field trials at Lansdown. Although the low-mimosine selections did indeed have lower mimosine than the control cultivars, their dry matter yield was also inferior (about t...

In rural regions, land use changes (LUC) are often the result of the decision-making of individual farmers. To influence this decision-making, compulsory and voluntary mechanisms are implemented. However, farmers’ decision-making is a heterogeneous process that depends on their ability and willin...

An agent-based approach to explore the effect of voluntary mechanisms on land use change: a case in rural Queensland, Australia
A wide range of fungi, two bacteria and several viruses and nematodes have been recorded throughout the tropics on a group of Cassia species defined as taxonomically and geographically related to Cassia rotundifolia. Although limited information was found on the relative importance of these patho...
Diseases of Aeschynomene spp. observed in forage evaluation trials in South America and Florida, U.S.A. are described and discussed. Newly discovered diseases include Polythrincium sp. leaf blotch, Calonectria sp. dieback, and Rhizoctonia solani Kuhn foliar blight. Diseases previously reported fr...

Recent discoveries that high prolificacy in sheep carrying the Booroola gene (FecB) is the result of a mutation in the BMPIB receptor and high prolificacy in Inverdale sheep (FecXI) is the result of a mutation in the BMP15 oocyte-derived growth factor gene have allowed direct marker tests to be d...
