Las ciudades presentan una biodiversidad asociada que subsiste en medio de las fuertes presiones antropogénicas que impone la urbanización. Cartagena de Indias es un Distrito del norte de Colombia que contiene un mosaico de ecosistemas costeros: arrecifes, litorales, humedales, manglares y bosques secos. La presencia de estos distintos ambientes ha...

Entre septiembre de 2017 y febrero de 2018 se realizaron muestreos de mariposas diurnas en siete zonas urbanas de la ciudad de Cartagena de Indias, usando redes entomológicas y trampas tipo Van Someren-Rydon. Se encontraron 1.210 individuos pertenecientes a 66 especies, 45 géneros y seis familias. Los valores más altos de abundancia se observaron e...

En el presente trabajo se estudia la diversidad de escarabajos coprófagos en tres zonas urbanizadas del departamento de Sucre, Colombia, cada una con características ecológicas distintas. Los individuos fueron capturados con trampas de caída cebadas. Se analizaron el esfuerzo de muestreo, las curvas de rango-abundancia y los índices de diversidad a...

Urbanization has caused the local extinction of several butterfly species around the world, while others have managed to thrive in urban areas. Butterflies of the genus Eumaeus are among the most striking and colorful lycaenid butterflies in the Americas, but their neurotoxic hostplants, cycads, are a highly threatened plant group. The main threats...

Human migration to urban centers has resulted in diverse environmental disturbances that affect biodiversity. Although urbanization has been highlighted as one of the main drivers of biodiversity endangerment, this topic is still poorly studied in many countries. In order to establish the status quo of the ecology of butterflies in urban centers, w...

The world has become an urban world, more than 50 % of the human population live in cities. The effects of urbanization are diverse, complex and wide; ranging from unbalanced biogeochemical cycles in urban areas, to the local extinction of several species in different cities around the globe. However, diverse biological groups live and thrive in ci...

Ceratotrupes fronticornis (Erichson) es un escarabajo estercolero de tamaño mediano, perteneciente a la subfamilia Geotrupinae (Coleoptera: Scarabaeoidea: Geotrupidae). Es endémico de México, distribuyéndose en la zona montañosa alta del Sistema Volcá- nico Transversal. En esta nota señalamos la presencia de esta especie en dos áreas urbanas (Cuaji...

Urbanization poses important environmental, social, and ecological pressures, representing a major threat to biodiversity. However, urban areas are highly heterogeneous, with some greenspaces (e.g., urban forests, parks, private gardens) providing resources and a refuge for wildlife communities. In this study we surveyed 10 taxonomic groups to asse...

Urbanization poses severe threats to biodiversity; thus, there is an urge to understand urban areas and their biological, physical, and social components if we aim to integrate sustainable practices as part of their processes. Among urban wildlife groups, butterflies have been used as biological indicators due to their high sensitivity to environme...

Immature stages of the tigerwing butterfly, Mechanitis menapis doryssus Bates (1864), were collected during 10 days of fieldwork southwest of the city of Xalapa, Veracruz, Mexico. Three species of host plants were identified as belonging to the genus Solanum L. (Solanaceae), all of them new records for Ithomiini host plants in Mexico, and two of th...

The growing number of urban ecology studies has raised concern about the importance of comprehending the ecological patterns and processes of urban areas in order to manage and plan them properly. In this study, we performed a rapid descriptive ecological assessment of the biodiversity patterns in a neotropical mid-sized urban area from a multi-tax...

Latin America is one of the most urbanized developing regions, however little is known about the biodiversity of its cities and the way this biodiversity is affected by landscape and local variables. We evaluated butterfly diversity in two Mexican cities by establishing four categories of urbanization: urban, suburban, areas of ecological protectio...

Between March and August 2005, diurnal butterflies were sampled with aerial nets and Van Someren-Rydon traps, in six urban zones and one suburban zone that cover approximately 210 ha of the municipality Santiago de Cali, in the department Valle del Cauca. The inventory recorded 193 species grouped in five families, Nymphalidae being the family with...
