“…Aquatic birds, such as Blue-winged Teal ( Spatula discors ) or Little Blue Heron ( Egretta caerulea ), were present in only three green spaces and comprised 17 species including migratory ones. We recorded three species endemic to the YP (Calmé et al., 2015): Yucatan Woodpecker ( Melanerpes pygmaeus ), Yucatan Jay ( Cyanocorax yucatanicus ), and Orange Oriole ( Icterus auratus ) and two exotic species in the area: Rock Pigeon ( Columba livia ) and Eurasian Collared-Dove ( Streptopelia decaocto ).…”

“…), the main city of the Yucatan Peninsula (YP), southeastern Mexico with more than 1.1 million people (Consejo Nacional de Población, 2015). YP is one of the Mexican biogeographic regions with highest levels of bird species richness (Navarro-Sigüenza et al., 2014), and it holds considerable importance for wintering and transient Nearctic-Neotropical species (Calmé et al., 2015). The area was originally covered by seasonally dry tropical forest characterized by a dry season that may last between 7 and 8 months (Torrescano-Valle & Folan, 2015).…”

Given current urbanization trends, understanding the factors that affect local biodiversity is paramount for designing sound management practices. Existing evidence suggests that the assembly of urban communities is influenced by the environmental filtering of organisms based on their traits. Here, we investigate how environmental characteristics including isolation measurements affect the functional composition of avian assemblages in green spaces of Merida, Mexico, a Neotropical city. We sampled 22 sites, analyzed point-count data collected during fall migration, and characterized the habitat with regard to floristic and structural vegetation attributes, vegetation cover within green spaces, urban infrastructure, and isolation. We assessed the relationship between habitat descriptors and bird functional traits using RLQ and fourth-corner tests and compared trait–environment associations between resident and wintering species. Our results showed that functional composition of resident bird assemblages was linked to the environmental characteristics of the site, while the functional composition of wintering species was not. In particular, the degree of isolation revealed to be an important determinant of trait composition. Plant species richness, particularly native tree and shrub species, were critical for the functional composition of resident birds in green spaces. Our findings suggested shifts in body mass from less to more isolated green spaces. Specifically, we observed that large-bodied species predominated in isolated green spaces. This information is useful given the predicted increases in habitat isolation and transformation of green spaces due to urbanization.

Actualmente, los ecosistemas enfrentan una gran pérdida de biodiversidad debido a perturbaciones antrópicas, lo cual que tiene efectos negativos en los procesos ecológicos. Para conocer el estado de conservación de un ambiente se pueden determinar especies indicadoras, que desempeñan un rol importante en distintos procesos ecológicos y son sensibles a los disturbios. El objetivo de este estudio fue determinar la diversidad y composición de aves en respuesta a diferentes perturbaciones del hábitat en el ejido Laguna Om, Quintana Roo, México, mediante conteo por puntos de agosto a septiembre de 2017. Se seleccionaron hábitats con diferente estado de conservación denominados: Selva, Laguna, Carretera, Potrero y Helechal. La mayor riqueza de especies se registró en los hábitats de Laguna y Carretera. Los patrones de abundancia de especies tolerantes a la perturbación fueron mayores en las áreas perturbadas. Encontramos mayor similitud en la composición de los gremios tróficos de las especies entre Laguna y Selva, y entre Helechal y Carretera, mientras que la composición en Potrero no mostró similitudes respecto a los otros hábitats. La diversidad y la composición de las especies de aves dependen de la complejidad estructural a nivel de hábitat, más que el tipo de perturbación que se asocia localmente.
