Adoption of crossbred cow technologies and increased food security among smallholder dairy farmers in the East African highlands by Ahmed, M., Ehui, Simeon K., Mohamed-Saleem, M.A.

“…The analysis of the factors affecting the health status revealed that womens’ practice and knowledge, and age of the mother and female headship are important determinants of the weight-for-age and weight for height scores. Also, participation in village level health programs has a significant effect (at 10% level) on the weight for height. …”

Genetic analysis of resistance to gray leaf spot of midaltitude maize inbred lines by Menkir, A., Ayodele, M.

“…Both general (GCA) and specific (SCA) combining abilities were significant (P < 0.001), with GCA accounting for >70% of the variation for GLS scores, days to silking, plant height, ear height, ear aspect, and ear rot; 68% for grain yield; and 60% for plant aspect (visual phenotypic appeal) score. …”

Assessing lodging resistance in rice: A comparison of two indirect testing methods by Torró, Isabel, Bretó, Pau, García-de-Izaguirre, Álvaro

“…Tiller angle difference was not significantly correlated with pulling strength, but it correlates with plant height (r = 0.56*). The scoring of tiller angle difference is simpler and less dependent on the evaluator than pulling resistance. …”

Widespread mangrove damage resulting from the 2017 Atlantic mega hurricane season by Taillie, Paul J., Roman-Cuesta, Rosa, Lagomasino, David, Cifuentes-Jara, Miguel, Fatoyinbo, Temilola, Lesley E, Ott, Poulter, Benjamin

“…Furthermore, wind speed, rainfall, and canopy height data showed that mangrove damage primarily resulted from high maximum wind speeds, but flooding (cumulative rainfall), previous storm history, and mangrove structure (canopy height) were also important predictors of damage. …”

Damages to residual stand in commercial thinnings by Bobik, Michal

“…The study aimed at investigating the relationship between thinning damages and stand characteristics such as basal area after thinning, dominant height, age at breast height, spacing and tree species. …”

Moose foraging patterns by Lindqvist, Sara

“…The Moose Damage survey could be used in favor of Browsing Pressure survey although both pine density and mean stand height also significantly affected the relationship between the methods. …”

Aerial Bud Bank and Structural Changes of Woody Species from Argentine Chaco in Response to Disturbances by Bravo, Sandra, Basualdo, María, Kunst, Carlos Roberto, Corro, Florencia del

“…ABB size diminished in all species studied when plant height (p = 0.0006) and plant cover (p < 0.0001) increased which could be related to most allocation of resources towards height growth and elongation of growth modules rather than to the differentiation of new shoots. …”
