Characterization of <em>Ulex europaeus<em> L. invasions of different ages, as a tool for ecological restoration of Andean forests, Colombia

Abstract (en):

Ulex europaeus invasions of different ages were characterized as a tool for ecological restoration of the Andean forest, (Area of Usme - south of Bogotá D. C., Colombia). Three ages of invasion were considered: 1-3 (recent invasion), 18-22 years (20 year invasion) and greater than 40 years (40 year invasion). Vegetation was sampled by the point intercept method in transects of 50 meters. The Importance Value Index (IVI), Physiognomic Dominance Index (IPF) and Shannon-Wiener diversity index were calculated. Richness and abundance data were compared using Generalized Linear Models (GLM). In the recent invasion the number of species was 29, in 20 year invasion, 65 and 40 year invasion, 53. The GLM showed that the values of Shannon diversity and abundance were significantly different between the recent invasion and invasions of 20 and 40 years. However, species richness did not differ among the three ages of invasion. Meanwhile, abundance values showed differences for the 20 year invasions, when compared with recent invasions and 40 year invasions. Finally, the Sørensen similarity index showed differences in the recent invasion when compared with the invasions of 20 and 40 years.

Abstract (es):

Se caracterizaron las invasiones de Ulex europaeus de diferente edad, como herramienta para la restauración ecológica del bosque altoandino (localidad de Usme, sur de Bogotá D.C., Colombia). Se consideraron tres edades de invasión: 1-3 años (invasión reciente), 18-22 años (invasión 20 años) y mayores a 40 años (invasión 40 años). La vegetación fue muestreada por el método del punto intercepto, en transectos de 50 metros. Se calcularon el índice de valor de importancia (IVI), el índice de predominio fisionómico (IPF) y el índice de diversidad de Shannon-Wiener. Se compararon datos de riqueza y abundancia mediante modelos lineales generalizados (GLM). En la invasión reciente el número de especies fue 29, en la de 20 años de 65 y en la de 40 años de 53. Los GLM evidenciaron que los valores de diversidad de Shannon y de abundancia fueron significativamente diferentes entre la invasión reciente y las invasiones de 20 y 40 años. Sin embargo, la riqueza específica no presentó diferencias entre las tres edades de invasión. Por su parte, los valores de abundancia presentaron diferencias ente la invasión de 20 años, comparada con las invasiones reciente y la de 40 años. Finalmente, el índice de similitud de Sørensen mostró diferencias de la invasión reciente al compararla con las invasiones de 20 y 40 años.
