Abstract T. candida is a shrub 2-3 m tall, thought to be indigenous to Malaysia, and has been introduced and become naturalized in many parts of the tropics, including: Vietnam, Bhutan, Myanmar, India, Sri Lanka, Papua New Guinea, Indonesia, New Zealand, Philippines, Hawaii, and Puerto Rico. It is drought-tolerant, and commonly used in agroforestry systems. It grows well on acid and impoverished soils. Its soil improving characteristics have led to its use as a pioneer plant, in contour hedgerows to prevent soil erosion on steep slopes, as a shade tree in agroforestry systems (Nguyen and Thai, 1993), and as a nurse tree for commercial timber species (e.g. for Shorea robusta in India; Krishnaswany, 1956). It is one of the most common green manure species planted in Vietnam. Extracts from T. candida have insecticidal properties (Stoll, 1996). The flowers and fruits are susceptible to damage from Maruca vitrata (Chan Dang Dinh, 1982).

Abstract T. catappa is a hardy, fast-growing, deciduous multipurpose tree, reaching 25 (-40) m tall and producing an edible fruit. It plays a vital role in coastline stabilization as a tree component of strandline plant communities in the western Indian Ocean, South-East Asia and the South Pacific. Under suitable conditions it is a well-formed tree and has been widely planted throughout the tropics for shade, ornament and nuts, especially along sandy seashores (Heinsleigh and Holaway, 1988; Little and Skolmen, 1989). It is much used in agroforestry systems in the Philippines.

Abstract I studied fruit-feeding by nine species of birds of paradise in Papua New Guinea from July 1978 through November 1980 and gathered 1,187 records of foraging at 31 species of trees and vines from 14 botanical families. Fruit consumed was consistently small-to moderate-sized (mean: 1 cm diameter), but fruit of different species of plants showed high morphological diversity. I classify the fruit of 31 plant species into three morphological groups: capsule, fig, and drupe/berry. Each of the primarily frugivorous birds of paradise was recorded taking fruits from 10-21 plant species, including representatives from each class. The monogamous Trumpet Manucode and Crinkle-collared Manucode were fig specialists. More than 80% of their diet was figs. The polygamous species of paradisaeids were more "generalized" fruit-feeders and took significant amounts of fruit from all three morphological categories. The most important types of fruit among the polygamous birds were capsular species (49% of diet). While fig species were visited by birds from many families, most nonfig trees hosted a narrower range of foragers, and two species of trees, Chisocheton weinlandii (Meliaceae) and Gastonia spectabilis (Araliaceae), were visited only by birds of paradise. The frugivorous habits of birds of paradise are similar in several respects to those of the neotropical cotingids and manakins. It is argued that while frugivory is an important component of the evolution of polygamous arena display in these birds, it cannot, by itself, explain why some birds are polygamous and others monogamous. Frugivory in the tropics is a complex syndrome that offers a number of ecological alternatives that, in turn, promote different behavioral adaptations.

New Strategies

The expansion and modernization of the cocoa area under new strategies, such as the use of adapted genetic material and the establishment of Agroforestry Systems with cocoa, under criteria of competitiveness and sustainability, require selecting sites with adequate biophysical conditions, which facilitate the optimization of resources for production. In this sense, we conducted a study in the Estación Agraria Cotové, of the Universidad Nacional de Colombia, located in a tropical dry forest life zone (TDF), at 540 meters of elevation, with an average temperature of 27 ºC, average annual precipitation annual of 1,031 mm and relative humidity less than 70 %. The yield components and productive potential of four cocoa clones, ICS 95, TSH565, CCN 51, and ICS 60, were evaluated. The cocoa clones were planted under two controlled sunlight habitats, generated by the timber species Gmelina arborea Roxb. (single-row and double-row arrangement), and two different canopy management of the cocoa plants (plagiotropic and orthotropic growth stimulus). The clones TSH 565 and CCN 51 showed the highest yields in the two harvest years. ICS 95 showed the lowest bean index. Regarding the pod index, no differences were observed between the cocoa clones. Clones TSH 565 and CCN 51 stood out as the earliest and most productive clones.

Cut Foliage

The demand for special forest products used in the floral industry has a rapidly expanding market. Woody cuts come from perennial shrubs, trees, or woody vines, and are used as floral design materials for the flowering branches, foliage, fruits, or stems. Evaluation of specialty and woody cut production is needed to determine if these plants may be adapted to sustainable agroforestry production systems. An agroforestry approach to woody cuts production for longleaf pine (Pinus palustris) producers in Florida is a natural approach given the relatively open canopy of this timber species and the occurrence of several native species with ornamental characteristics that are currently utilized on a small scale for woody cuts production. The present approach to evaluating the suitability of these systems utilizes the following objectives: 1) Evaluate the production potential of ornamental species in monoculture and agroforestry silviculture systems and determine the biophysical interactions between system components. This objective will assess system design and its role on system productivity; determine time to ornamental yield. 2) Quantify the cost of establishing ornamentals for woody cuts production in both monoculture and agroforestry systems. This objective will identify and track overhead/fixed costs and variable costs associated with the ornamental cuts and timber crops for monoculture and agroforestry production systems over a 3-year period. 3) Investigate potential markets for the distribution and sale of cut foliage, flowers or stems. This objective will lead to consultations with florists and cut foliage wholesalers about potential market volume, price, and specifications for products produced within the longleaf pine agroforestry production system.

The Tropics

Tropical forests represent vast carbon stocks and continue to be key carbon sinks and buffer climate changes. The international policy constructed several mechanisms aiming at conservation and sustainable use of these forests. Illegal logging is an important threat of forests, especially in the tropics. Several laws and regulations have been set up to combat illegal timber trade. Despite significant enforcement efforts of these regulations, illegal logging continues to be a serious problem and impacts for the functioning of the forest ecosystem and global biodiversity in the tropics. Microscopic analysis of wood samples and the use of conventional plant DNA barcodes often do not allow to distinguish closely-related species. The use of novel molecular technologies could make an important contribution for the identification of tree species. In this study, we used high-throughput sequencing technologies and bioinformatics tools to obtain the complete de-novo chloroplast genome of 62 commercial African timber species using the genome skimming method. Then, we performed a comparative genomic analysis that revealed new candidate genetic regions for the discrimination of closely-related species. We concluded that genome skimming is a promising method for the development of plant genetic markers to combat illegal logging activities supporting CITES, FLEGT and the EU Timber Regulation.
