Sin embargo, es mucho lo que se desconoce de su comportamiento en ambientes urbanos. El objetivo del presente estudio fue conocer los hábitos de nidificación de Nannotrigona mellaria en un ambiente urbano. Se realizó un muestreo en el campus Meléndez de la Universidad del Valle, registrando los nidos y el número de colonias por sitio, con lo que se construyó un mapa de distribución usando el programa &#8220;DIVA-GIS&#8221;. Para evaluar la distribución de los nidos se realizó un análisis no espacial de bondad de ajuste a la distribución binomial negativa con una prueba de Chi2. Adicionalmente, se realizó un Análisis Espacial por Índices de Distancia &#8220;SADIE&#8221;. Se localizaron un total de 242 nidos, de los cuales 130 se encontraron en Pithecellobium dulce (Fabaceae: Faboideae), seguido por los nidos en edificaciones con 91. Los análisis indicaron que los nidos presentan una distribución espacial agregada en el campus de la Universidad del Valle, lo anterior se debe probablemente a diversos factores como la localización y abundancia de recursos, los espacios aprovechables para la nidificación (troncos huecos o grietas en edificaciones) y las limitaciones en cuanto a la capacidad máxima de vuelo debido a su tamaño. A pesar de la preferencia por nidificar en P. dulce, las edificaciones son importantes para esta especie y brindan condiciones necesarias para el establecimiento de las colonias en ambientes urbanos.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract: Meliponini bees are important pollinators in natural habitats and their distribution may be affected differently by humans, the buildings causing changes in micro-climate and vegetation structure and composition, which may affects stingless bee communities. However, there is much to know about their behavior in these conditions. The aim of this study was to describe nesting habits of Nannotrigona mellaria at an urban environment. Sampling was conducted at the Universidad del Valle, Melendez campus, the nest location and number of colonies per site, were recorded and mapped using the program DIVA-GIS. The nest distribution was analyzed with a non-spatial analysis performed by adjusting the data to the negative binomial distribution with a Chi2 test. Additionally, Spatial Analysis by Distance Indices (SADIE) was performed. We found 242 nests, of which 130 were on Pithecellobium dulce (Fabaceae: Faboideae), and 91 where found in buildings. Analyses suggested that Nannotrigona mellaria nests have an aggregated distribution at the Universidad del Valle, this probably due to factors such as the location and abundance of resources, usable spaces for nesting and limitations as to the maximum flight because the size of the bees. In addition, P. dulce was mainly used to establish colonies, however, it is clear that buildings are an important space resource for this species and provide the necessary conditions for the establishment of colonies in an urban habitat.]]></p></abstract>
