Vertical distribution of birds in a temperate forest with different perturbation levels
In the period from February through June 2004, the presence of different bird species was studied in two zones located at the Experimental Forest Station Zoquiapan (EFEZ for its Spanish acronym), state of Mexico, one with slightly disturbed pine forest (ZOQ 1) and another with mixed perturbed forest...

| description | In the period from February through June 2004, the presence of different bird species was studied in two zones located at the Experimental Forest Station Zoquiapan (EFEZ for its Spanish acronym), state of Mexico, one with slightly disturbed pine forest (ZOQ 1) and another with mixed perturbed forest (ZOQ 2). The points recounting method with fixed radio for bird monitoring was used as well as the square embedded method and the quadrant with a central point, the last one to allow sampling the vegetation. The distribution of birds in vertical vegetation strata was characterized and compared using Poisson regression analysis and frequency observation; furthermore, a specific analysis was developed to describe the vegetal structure in both zones. The vertical distribution of birds followed four patterns: low (B), high (A), high-low (AB) and indeterminate (I). The individual’s abundance per stratum had a different value within strata and zones; in both sites the upper stratum showed a greater abundance than in the low and medium ones, although the number of individuals per specie registered in each stratum was the greatest in the perturbed mixed forest. The relative importance value (VIR for its Spanish acronym) of vegetation confirmed than ZOQ 1 had Pinus hartwegii as the predominant specie with some shrubs of Penstemon gentianoides and Senecio asteracae. ZOQ 2 was a mixed forest comprised by S. asteracae, P. gentianoides, Lupinus montanus shrubs and Alnus jorullensis, P. hartwegii and Abies religiosa trees. The height histograms determined two and three vertical strata, respectively. |

De febrero a junio del 2004, la presencia de diferentes especies de aves fue estudiada en dos zonas localizadas en la Estación Forestal Experimental Zoquiapan (EFEZ), Estado de México: una con bosque de pino poco alterado (ZOQ 1) y otra con bosque mixto perturbado (ZOQ 2). Se empleó el método de recuento en puntos con radio fijo para el monitoreo de aves; así como los métodos de cuadros empotrados y cuadrantes con punto central para el muestreo de la vegetación. Se caracterizó y comparó la distribución de aves en estratos verticales de la vegetación, mediante análisis de regresión Poisson y por frecuencia de observación; además, se desarrollaron análisis específicos para describir la estructura vegetal de ambas zonas. La distribución vertical de las aves siguió cuatro patrones: bajo (B), alto (A), alto-bajo (AB) e indeterminado (I). La abundancia de individuos por estrato tuvo un valor diferente entre estratos y zonas; en ambas, el estrato superior tuvo una mayor abundancia que el inferior y medio. Sin embargo, el número de individuos por especie, registrado en cada estrato, fue mayor en el bosque perturbado. El Valor de Importancia Relativa (VIR) de la vegetación confirmó que ZOQ 1 es un rodal dominado por Pinus hartwegii y algunas arbustivas de Penstemon gentianoides y Senecio asteracae. ZOQ 2 es un bosque mixto conformado por arbustos de S. asteracae, P. gentianoides, Lupinus montanus y árboles de Alnus jorullensis, P. hartwegii y Abies religiosa. Los histogramas de alturas definieron dos y tres estratos verticales, respectivamente.
