Wave effect and shyness phenomenon in homogeneous forests of Alnus acuminata
Wave effect and the shyness phenomenon in Alnus acuminata (Kunth) are canopy parameters rarely studied, but they are important in wood quality for standing trees, therefore, a morphometric modeling of crowns for A. acuminata was carried out in homogeneous forests in the Northern Sierra of Puebla.

| description | Wave effect and the shyness phenomenon in Alnus acuminata (Kunth) are canopy parameters rarely studied, but they are important in wood quality for standing trees, therefore, a morphometric modeling of crowns for A. acuminata was carried out in homogeneous forests in the Northern Sierra of Puebla. In 20 rectangular areas of 1000 m2, it was evaluated: total height (TH), diameter at breast height (DBH), crown diameter (CD) and canopy coverage (CC). To the data that did not meet the normality assumption, the Kruskal Wallis test was applied; for those who did, the analysis of variance (ANOVA) was used, with tests of mean comparison by Tukey (α ≤ 0.05). The forest value index was 14.99, whereby its two-dimensional structure is normal, based on the DBH, TH and CC. The average slenderness index was 93.52, making the trees not stable to mechanical damage. The vital space index was 38.92, which is high and shows a better development of the trees with low intraspecific competition. At the canopy level, we observed a pattern that follows a rising wave effect, oscillatory and constant in groups of 10 trees. The shyness phenomenon showed an average crack opening of 27.39 cm between crowns whereby this phenomenon is well-defined for the species. It is concluded that in the cups of A. acuminata, the wave effect occurs because of the inequality in the acquisition of resources, and one way to minimize this inequality is through the phenomenon of botanical shyness. |

El efecto de onda y el fenómeno de timidez en Alnus acuminata (Kunth) son parámetros de copa raramente estudiados, pero importantes en la calidad de la madera de árboles en pie, por lo cual, se realizó un modelaje morfométrico de las copas de A. acuminata en bosques homogéneos en la Sierra Norte de Puebla. En 20 sitios rectangulares de 1000 m2, se evaluó: altura total (AT), diámetro normal (DN), diámetro de copa (DC) y cobertura de copa (CC). A los datos que no cumplieron el supuesto de normalidad, se les aplicó la prueba de Kruskal Wallis; para los que sí cumplieron, se empleó el análisis de varianza (ANOVA), con pruebas de comparación de medias por Tukey (α ≤ 0.05). El índice de valor forestal fue de 14.99, por lo que su estructura bidimensional es normal, con base en DN, AT y CC. Su índice de esbeltez promedio fue de 93.52, lo que hace al arbolado poco estable al daño mecánico. El índice de espacio vital fue de 38.92, es alto y evidencia un mejor desarrollo de los árboles con baja competencia intraespecífica. A nivel del dosel se observó un patrón que sigue un efecto de onda ascendente, oscilatorio y constante, en grupos de 10 árboles. El fenómeno de timidez mostró una apertura de grieta promedio de 27.39 cm entre copas, por lo cual, este fenómeno se encuentra bien definido para la especie. Se concluye que en las copas de A. acuminata, se observa el efecto de onda como consecuencia de la desigualdad en la adquisición de recursos, pero una forma de minimizar esta desigualdad es mediante el fenómeno de timidez botánica.
