Genomics of Tropical Fruit Tree Crops

Spatial patterns of a tropical tree species growing under an eucalyptus plantation in South-East Brazil.

The objectives of this study were to evaluate the influence of propagules source and the implication of tree size class on the spatial pattern of Xylopia brasiliensis Spreng. individuals growing under the canopy of an experimental plantation of eucalyptus. To this end, all individuals of Xylopia brasiliensis with diameter at soil height (dsh) > 1 cm were mapped in the understory of a 3.16 ha Eu...

Non-labile Soil 15Nitrogen Retention beneath Three Tree Species in a Tropical Plantation

T species composition affects forest biogeoSoil organic matter is the largest sink for N additions to forests. chemistry because species differ in their rates of Species composition may affect soil N retention by altering the amount nutrient and energy cycling (Zinke, 1962; Boettcher and or proportion of added N stored in non-labile organic pools. We Kalisz, 1990; Hobbie, 1992; Wardle et al., 1...

Diseases in tropical and plantation crops as affected by climate changes: current knowledge and perspectives

Tropical and plantation crops include important crops for food security and alternative energy resources. Even so, there are few studies on the impact of climate change on diseases of these crops. Findings from previous studies concerning some climate-change effects on diseases of coffee, sugarcane, eucalyptus, cassava, citrus, banana, pineapple, cashew, coconut and papaya have been summarized ...

Ecological Impact on Nitrogen and Phosphorus Cycling of a Widespread Fast-growing Leguminous Tropical Forest Plantation Tree Species, Acacia mangium

Symbiotic nitrogen fixation is one of the major pathways of N input to forest ecosystems, enriching N availability, particularly in lowland tropics. Recently there is growing concern regarding the wide areas of fast-growing leguminous plantations that could alter global N2O emissions. Here, we highlight substantially different N and phosphorus utilization and cycling at a plantation of Acacia m...
