Flavonoids in Tropical Citrus Species
Journal of Agricultural and Food Chemistry, 2011HPLC with PDA and MS(2) detection was used to identify and quantify flavonoids in the tropical citrus species Citrus microcarpa , Citrus hystrix , Citrus medica var. 1 and 2, and Citrus suhuiensis . Most of these species contained high amounts of flavones, flavanones, and dihydrochalcone C- and/or O-glycosides, which were identified on the basis ...

The Future of Tropical Species on a Warmer Planet
Conservation Biology, 2009Abstract: Modern global temperature and land cover and projected future temperatures suggest that tropical forest species will be particularly sensitive to global warming. Given a moderate greenhouse gas emissions scenario, fully 75% of the tropical forests present in 2000 will experience mean annual ...

Ecology and genetics of tropical rhizobia species
Biotechnology Advances, 1985Biological nitrogen fixation (BNF) technology with special reference to Rhizobium-legume symbiosis is growing very rapidly with the hope of combatting world hunger by producing cheaper protein for animal and human consumption in the Third World. One can see rapid progress made in the biochemistry and molecular biology of symbiotic nitrogen fixation in ...

Germination characteristics of tropical and sub-tropical rangeland species
The Rangeland Journal, 2011A study was made of the germination characteristics of a broad spectrum of rangeland species by studying their behaviour under different conditions. Seeds of common species (both native and exotic) were collected from tropical (north-east Queensland) (36 species) and sub-tropical areas (south-east Queensland) (47 species).

The evaluation of tropical pasture species in the Transvaal
Proceedings of the Annual Congresses of the Grassland Society of Southern Africa, 1977The performance and compatibility of seven tropical legumes grown in association with two grasses were compared over four years at two localities in the Transvaal.The legume and grass species evaluated were Desmodium uncinatum cv. silverleaf, D. intorturn cv. greenleaf, D. sandwicense, Macrotiloma axillare, Glycine wightii cv.

Allelopathy in tropical and subtropical species
Phytochemistry Reviews, 2018The ability of certain plants to synthesize allelochemicals that disrupt the germination, development, reproduction and/or survival of organisms that compete with them for resources has been observed in a variety of environments worldwide. Tropical and subtropical regions are particularly conducive to the evolution of allelopathic survival strategies ...

Species Concepts, Species Boundaries and Species Identification: A View from the Tropics
Systematic Biology, 2005The species has been treated as a fundamental unit in biology (Hull, 1977) and, more recently, in biodiversity conservation (Sites and Crandall, 1997). Almost all studies in biology, whether at the level of molecules, cells, individuals or populations, are typically referenced to the level of the species.

Agaricus is a large genus of mushrooms including species of nutritional and medicinal interest. With research programs developed over the last decade, a larger diversity of Agaricus came to light. The present review focuses on tropical species of Agaricus and their classification, including a discussion of the definition of tropical species, a brief ...

Towards quantifying tropical tree species richness in tropical forests
International Journal of Remote Sensing, 2009This letter reports tests of whether the normalized difference vegetation index (NDVI) from Landsat Enhanced Thematic Mapper Plus (ETM+) and radar backscatter (C-, L-and P-bands) from Airborne Synthetic Aperture Radar (AIRSAR) imagery can be used to estimate tree species richness from 25 1-ha plots within continuous lowland forest types (dry, moist ...

Micropropagation of Tropical Woody Species
2003During the last thirty years plant micropropagation has been one of the most significant contributions of biotechnology to the horticultural industry (Giles and Friesen, 1994). The possibility of mass propagation of elite, endangered, or difficult-to-propagate genotypes, in relatively small areas and time period, is the most important characteristic of
