Influence of within-and between-row mulching on soil temperature, soil moisture, root development and yield of maize (Zea mays L.) in a tropical soil por Lal, R.

“…Soil temperature in the row zone was 2–7°C lower than in the inter-row zone at 15.00 h. Since mulched strips had high earthworm activity, bulk density and penetrometric resistance were low compared with unmulched zones. …”

Identification of novel QTL associated with whitebacked planthopper (WBPH) and brown planthopper (BPH) resistance in the rice line RP2068 por Sahu, Nihar, Naik, Sabhavat Bhaskar, Padmavathi, G., Gangurde, Sunil S., Pandey, Manish K., Bentur, Jagadish Sanmallappa, Divya, Dhanasekar

“…This study aimed to identify QTL governing three traits of the resistance against the two planthoppers such as damage score (DS), nymphal survival (NS) and days to wilt (DW) using the 94 RIL population derived from the cross TN1/RP2068 utilizing 125 SSR and 1500 SNP markers. In case of the whitebacked planthopper (WBPH) five major and three minor QTL while for the brown planthopper (BPH) four major and seven minor QTL were identified to be associated with these three traits. …”

Conservation priorities for Prunus africana defined with the aid of spatial analysis of genetic data and climatic variables por Vinceti, B., Loo, J., Gaisberger, H., Zonneveld, M.J. van, Schueler, S., Konrad, H., Kadu, C.A.C., Geburek, T.

“…The potential distribution of P. africana was then modeled based on a dataset of 1,500 georeferenced observations. This enabled an assessment of whether the priority populations identified are exposed to threats from agricultural expansion and climate change, and whether they are located within the boundaries of protected areas. …”

Extensive seed and pollen dispersal and assortative mating in the rain forest tree Entandrophragma cylindricum (Meliaceae) inferred from indirect and direct analyses por Monthe, F.K., Hardy, Olivier J., Doucet, J.L., Loo, J., Duminil, J.

“…Extensive pollen‐ and seed‐mediated gene flow is further supported by the weak, fine‐scale spatial genetic structure (Sp statistic = 0.0058), corresponding to historical gene dispersal distances (σg) reaching approximately 1,500 m. Using an original approach, we showed that the relatedness between mating individuals (Fij = 0.06) was higher than expected by chance, given the extent of pollen dispersal distances (expected Fij = 0.02 according to simulations). …”
