“…Several of these species are still present regionally in nearby localities of the Farallones de Cali National Park, and further explorations may find others (Palacio et al. ). Although populations in the periphery of their ranges may not be intrinsically vulnerable (Channell & Lomolino ), a decrease in connectivity limits the dispersal of species whose source populations are found in other regions or located at lower or higher elevations.…”

Long-term studies to understand biodiversity changes remain scarce-especially so for tropical mountains. We examined changes from 1911 to 2016 in the bird community of the cloud forest of San Antonio, a mountain ridge in the Colombian Andes. We evaluated the effects of past land-use change and assessed species vulnerability to climate disruption. Forest cover decreased from 95% to 50% by 1959, and 33 forest species were extirpated. From 1959 to 1990, forest cover remained stable, and an additional 15 species were lost-a total of 29% of the forest bird community. Thereafter, forest cover increased by 26% and 17 species recolonized the area. The main cause of extirpations was the loss of connections to adjacent forests. Of the 31 (19%) extirpated birds, 25 have ranges peripheral to San Antonio, mostly in the lowlands. Most still occurred regionally, but broken forest connections limited their recolonization. Other causes of extirpation were hunting, wildlife trade, and water diversion. Bird community changes included a shift from predominantly common species to rare species; forest generalists replaced forest specialists that require old growth, and functional groups, such as large-body frugivores and nectarivores, declined disproportionally. All water-dependent birds were extirpated. Of the remaining 122 forest species, 19 are vulnerable to climate disruption, 10 have declined in abundance, and 4 are threatened. Our results show unequivocal species losses and changes in community structure and abundance at the local scale. We found species were extirpated after habitat loss and fragmentation, but forest recovery stopped extirpations and helped species repopulate. Land-use changes increased species vulnerability to climate change, and we suggest reversing landscape transformation may restore biodiversity and improve resistance to future threats.

“…Otras especies como: Agapornis roseicollis, Nymphicus hollandicus, Melopsittacus undulatus, Psittacara erythrogenys y Lonchura oryzivora, son introducciones más recientes (principios de siglo XXI) y han sido observadas por los autores en Cali y alrededores (Palacio et al, 2017;eBird Basic Dataset, 2019;Fierro-Calderón & Fierro-Calderón, 2020). Para el caso de Lonchura oryzivora no se ha observado evidencia reproductiva, pero las poblaciones están aumentando por lo que asumimos que se reproducen en el departamento.…”

La avifauna del departamento del Valle del Cauca, Colombia, ha sido uno de los grupos biológicos mejor estudiados en Colombia desde finales del siglo XIX. Producto de estos ejercicios de compilación de información, los estimados de la riqueza de especies varían entre 818 y 1025 especies. Recopilamos información de registros de aves de diferentes fuentes y obtuvimos un listado de 989 especies de aves confirmadas para el departamento y 13 especies que fueron catalogadas como potencialmente presentes. Documentamos ocho especies introducidas que no tienen registros publicados o son anecdóticos en Colombia. Futuras expediciones o investigaciones deberían enfocarse en llenar los vacíos de información de aves que se concentran en el cañón del río Garrapatas, y el área al sur de Buenaventura y la cordillera Central.

The Economic Value of Wetlands in Urban Areas: The Benefits in a Developing Country

2022

Urban growth has impacted natural ecosystems such as wetlands. This situation destabilizes the beneficial contributions of nature, generating a socioeconomic effect. There is a need to quantify the benefits of wetlands in developing countries and urban areas, where the growth of cities is fastest. This is the first valuation study of urban and peri-urban wetlands in Colombia. The methodology includes a benefit transfer (BT) method with a geographical information system (GIS) and an exploratory governance analysis. Because there are few studies on the economic valuation of urban wetlands in Latin America, we present a methodology of interest, which can be easily replicated in other cities of this subcontinent. Based on an economic approach, our results find that 76% of the total value of wetlands is provided by ecosystem services (ES) of existence and legacy value, followed by maintenance of the life cycle of migratory species and water supply. Urban areas are identified where users benefit more than areas where the population exerts greater pressure on wetlands. Weak governance is due to the disarticulation between regulation, land-use planning, and the social-ecological system. This research contributes to urban wetland management policies, as well as to sustainable solutions in cities.
