Opis:
The agronomic management of maize (Zea mays L.) modifies the structure and composition of maize grain and its products like flour, masa, and tortillas. Results have shown that the protein content in flour obtained from maize grains treated with nejayote applied at 150 m3 ha-1 (10.36 g × 100 g-1) and nejayote applied at 75 m3 ha-1 with ovine manure applied at 25 t ha-1 (10.17 g × 100 g-1) was higher than that determined in flour treated with chemical fertilizer (10.05 g × 100 g-1). The flours obtained from maize fertilized without nejayote showed the highest viscosity values and the lowest values were for chemical fertilizer (2816 mPa s) and 75 m3 ha-1 of nejayote with ovine manure applied at 25 t ha-1 (2498 mPa s). The highest elastic and viscous moduli were obtained for masa with the following fertilization regimes: 75 m3 ha-1 of nejayote with 25 t ha-1 of ovine manure, and 150 m3 ha-1 of nejayote with 25 t ha-1 of ovine manure and the lowest values of these parameters were obtained for 75 m3 ha-1 of nejayote with 50 t ha-1of ovine manure. The cohesiveness of masa was the lowest for maize fertilized with nejayote applied at 75 to 150 m3 ha-1, and 50 t ha-1 of ovine manure. The highest concentration of 150 m3 ha-1 for nejayote and the lowest level for ovine manure applied at 25 t ha-1 had a positive influence on the production of nixtamal and tortilla.

Opis:
In arid environments, protist diversity is higher in soil covered by vegetation than in bare soil and is also likely to vary in line with the marked seasonal patterns; however, these patterns have not been explored in detail in arid zones. Herein, we used culture – and morphological-based approaches to describe patterns of amoeboid protist diversity in  vegetated and bare soil areas from the intertropical desert of Tehuacán, Mexico, during dry and wet seasons. Overall, 27 protist species belonging to Amoebozoa, Discoba and Rhizaria were retrieved using culture-dependent methods. Among the soil protist groups found, Discoba (principally represented by Heterolobosea) was always the most prevalent taxa. Protist diversity was different between soil with vegetation and bare soil, principally during the dry season. Moreover, the electrical conductivity and pH of the soil were correlated with the protist species during the wet season. Our results support the hypothesis that soil protist diversity patterns exhibit a seasonal variation between dry  and wet seasons. This seasonal variation likely relies on water availability, although the role of other environmental factors cannot be completely ruled out. In addition, the soils with vegetation could be a refuge for the amoeboid protists during the harsh soil conditions of dry seasons.

Opis:
For a herbaceous species, the inverse of the fresh leaf surface density, the Hughes constant, is nearly conserved. We apply the Hughes constant to develop an absolute method of leafarea measurement that requires no regression fits, prior calibrations or oven-drying. The Hughes constant was determined in situ using a known geometry and weights of a sub-set obtained from the fresh leaves whose areas are desired. Subsequently, the leaf-areas (at any desired stratification level), were derived by utilizing the Hughes constant and the masses of the fresh leaves. The proof of concept was established for leaf-discs of the plants Mandevilla splendens and Spathiphyllum wallisii. The conservativeness of the Hughes constant over individual leaf-zones and different leaftypes from the leaves of each species was quantitatively validated. Using the globally averaged Hughes constant for each species, the leaf-area of these and additional co-species plants, were obtained. The leaf-area-measurement-by-mass was cross-checked with standard digital image analysis. There were no statistically significant differences between the leaf-area-measurement-by-mass and the digital image analysis measured leaf-areas and the linear correlation between the two methods was very good. Leaf-areameasurement- by-mass was found to be rapid and simple with accuracies comparable to the digital image analysis method. The greatly reduced cost of leaf-area-measurement-by-mass could be beneficial for small agri-businesses in developing countries.
