Root-Induced Iron Oxidation, pH Changes and Zinc Solubilization in the Rhizosphere of Lowland Rice por Kirk, G.J.D., BAJITA, J.B.

“…The zones of accumulation and depletion coincided with zones of Fe(III) accumulation and soil acidification in which the pH decreased from the bulk soil value of 7.3 by over 0.2 pH units; i.e. a two‐fold increase in H+ concentration, The acidification was the result of H+ released from the roots to balance excess intake of cations over anions, and H+ generated in the oxidation of Fe(H) by root‐released O2. …”

Towards sustainable management of mixed dipterocarp forests of South-east Asia: moving beyond minimum diameter cutting limits por Sist, P., Fimbel, R., Sheil, Douglas, Nasi, Robert, Chevallier, M.H.

“…These guidelines, a pragmatic reflection of science and ‘best guess’ judgement, include: (1) integration of reduced-impact logging practices into normal management operations; (2) cutting of eight trees per hectare or less (with a felling cycle of 40–60 years to be determined according to local conditions); (3) defining minimum diameter cutting limits according to the structure, density and diameter at reproduction of target species; (4) avoiding harvesting species with less than one adult tree per hectare (diameter at breast height [dbh] larger and equal to 50cm over an area of 50–100 ha); (5) minimizing the size and connectivity of gaps (<600m2 whenever possible); (6) refraining from treatments such as understorey clearing; and (7) providing explicit protection for key forest species and the ecological processes they perform. …”

Quantification of the relative importance of trypanotolerance measurements on productivity of N'Dama cattle (Addendum) por Wissocq, N.M., D'Ieteren, G.D.M., Trail, J.C.M., Kakiese, O.

“…A reduction of one standard deviation in length of time infected increased growth by 9.8 per day or 6.5 percent. a reduction of one standard deviation in parasitaemia score increased growth by 9.0 g per day or 6.0 percent, and an increase of one standard deviation in average PCV increased growth by 8.4 g per day or 5.6 percent. The necessity for simultaneously considering the infection aspects of trypanosome species, length of time parasitaemic and intensity of parasitaemia, and the anaemia measure of average PCV, is illustrated by their approximately equal effects on the final performance trait of daily liveweight gain. …”
