Towards increased shading capacity: A combined phenotypic and genetic analysis of rice shoot architecture por Huber, Martina, Julkowska, Magdalena M., Snoek, L. Basten, van Veen, Hans, Toulotte, Justine, Kumar, Virender, Kajala, Kaisa, Sasidharan, Rashmi, Pierik, Ronald

“…The identified haplotypes can be used in breeding programmes to improve weed suppression by rice, thus contributing to sustainable agriculture.Summary In modern rice farming, one of the major constraints is weed proliferation and the entailed ecological impact of herbicide application. This requires increased weed competitiveness in current rice varieties, achieved via enhanced shade casting to limit the growth of shade‐sensitive weeds. …”

Climate change and forest genetic resources - state of knowledge, risks, and opportunities por Loo J, Fady, B., Dawson, I., Vinceti, B., Baldinelli, G.

“…Lack of information on the following hinders our ability to manage climate change impacts better: (1) little is known about the sequences and functions of the genes conferring adaptation; (2) the genetic and epigenetic basis of phenotypic plasticity and its role in producing responses to environmental alterations is unclear; (3) the basic life-history characteristics, ecological determinants and geographic distributions of many trees are not well studied; and (4) meaningful syntheses of such information into predictive models of change and response are poorly developed.…”

Effect of temperature on the life history parameters of noctuid lepidopteran stem borers, Busseola fusca and Sesamia calamistis por Khadioli, N., Tonnang, Henri E.Z., Ong'amo, G., Achia, Thomas, Kipchirchir, I., Kroschel, Jürgen, Le Ru, B.

“…The lower lower thermal threshold found for B. fusca than for S. calamistis and the higher upper thermal threshold found for S. calamistis than for B. fusca explain in part the observed distribution of both species in sub‐Saharan Africa with S. calamistis occurring in all the agro‐ecological zones but being usually more common than B. fusca in savannah lowland and B. fusca reported mainly from mid and high altitude areas.…”
