Blending high-resolution satellite rainfall estimates over urban catchment using Bayesian Model Averaging approach por Asfaw, Wegayehu, Rientjes, T., Haile, Alemseged Tamiru

“…New hydrological insights: Main findings from this study are: (i) the blended product outperformed the individual SRE products by notably improving correlation with in-situ observed rainfall, and reducing the error of the estimated rainfall, (ii) the blended and individual SRE products performed better in the highlands than the lowlands of the catchment, and (iii) the amount of daily rainfall during the main-rainy season was mostly overestimated by the individual SRE products but was fairly estimated by the blended product. …”

Effects of season-dependent irradiance levels and nitrogen-deficiency on photosynthesis and photoinhibition in field-grown rice (Oryza sativa) por Chen, Yizhu, Murchie, Erik H., Hubbart, Stella, Horton, Peter, Peng, Shaobing

“…Although Rubisco contents were lower in ND plants, photosynthesis in situ did not decline proportionally. For NS plants, Chlorophyll content, but not Rubisco content, was season‐dependent and results are discussed in terms of the interaction between irradiance use and N content of rice leaves.…”

Extensive ribosomal DNA amplification during Andean common bean (Phaseolus vulgaris L.) evolution por Pedrosa Harand, Andrea, Souza Almeida, C.C. de, Mosiolek, M, Blair, Matthew W., Schweizer, D., Guerra, M.

“…The extent of 5S and 45S ribosomal DNA (rDNA) variation was investigated in wild and domesticated common beans (Phaseolus vulgaris) chosen to represent the known genetic diversity of the species. 5S and 45S rDNA probes were localized on mitotic chromosomes of 37 accessions by fluorescent in situ hybridization (FISH). The two 5S rDNA loci were largely conserved within the species, whereas a high variation in the number of 45S rDNA loci and changes in position of loci and number of repeats per locus were observed. …”

Optimizing the use of breed types in developing country livestock production systems: A neglected research area por Marshall, Karen

“…Such strategic research would include (i) assessing the impact of differing breed types in developing country livestock productions systems, from a range of viewpoints including intrahousehold livelihood benefit, food and nutrition security at different scales, and environmental sustainability; (ii) identification of specific livestock production systems within developing countries, and the type of livestock keepers within these system, that are most likely to benefit from new breed types; and (iii) identification of new breed types as candidates for in-situ testing within these systems, such as through the use of spatial analysis to identify similar production environments combined with community acceptance studies. …”

Seed yam (Dioscorea rotundata Poir) production, storage, and quality in selected yam zones of Nigeria por Asiedu, Robert, Akoroda, M.O., Aighewi, B.A.

“…Between 50.0 and 65.0% of farmers in Asaba treated seed yams with purchased chemicals before planting to protect against yam beetle attack, while in other locations less than 35.0% did any form of treatment. Storage in situ or planting shortly after harvest was widely practiced in Oyo North, Lokoja and Lafia areas. …”

Oppotunities for biotechnology in cowpea por Monti, L., Murdock, L., Thottappilly, G.

“…A molecular map of cowpea has been constructed using RFLP markers, and this has already facilitated the localization of certain quantitative trait loci; gene chromosome localization using in situ hybridization is in progress. Appropriate bioassays have been developed that have facilitated the identification of candidate genes for insect pest resistance in cowpea, including Bacillus rhttrins>ensis protoxin genes, and genes coding a-amylase inhibitor, protease inhibitor, and lectins. …”
