Ant Communities (Hymenoptera: Formicidae) in a Protected Urban Park in Northeast Mexico

Rev. biol. trop; 72 (1), 2024
Abstract Introduction: The creation of protected natural areas within urban environments has played an essential role in providing small reservoirs of native vegetation and refuges for endemic species. However, knowledge of how land management and landscape design can influence the different community ...

Riqueza y diversidad de hormigas (Hymenoptera: Formicidae) según uso de suelo en dos paisajes agroforestales de Colombia

Rev. biol. trop; 71 (1), 2023
Introducción: Las hormigas cumplen funciones ecológicas importantes en muchos ecosistemas, y son altamente sensibles a los cambios en el uso del suelo. Sin embargo, la respuesta ante estos cambios está poco documentada, a grandes escalas espaciales y en distintos usos de suelo, en ecosistemas poco est...

New records of three Neotropical arboreal ant species of Camponotus, subgenus Dendromyrmex (Hymenoptera: Formicidae) for the southern Amazon, including biological information

Acta amaz; 49 (1), 2019
Camponotus (Formicinae) is the most specious and abundant genus of the family Formicidae. The genus is represented by ants that both forage and nest in the most diverse terrestrial and arboreal environments. Among the arboreal species of Camponotus are those of the subgenus Dendromyrmex. We recorded, for...

Generalized papular-purpuric eruption due to Solenopsis fugax bites

An. bras. dermatol; 93 (4), 2018
Abstract: A 59-year-old atopic man referred to for the onset of a diffused itching papular-purpuric eruption involving his trunk and legs but without systemic symptoms. History revealed that he started feeling itching after spending few hours in his basement. Direct examination of the environmental dust ...

Richness and structure of ant assemblies (Hymenoptera: Formicidae) in Atlantic forest in southern Brazil

An. acad. bras. ciênc; 89 (4), 2017
ABSTRACT Ant diversity is influenced by the structural complexity of the environment. Ants are thus an ecologically important group due to their potential to serve as indicators of environmental quality. The objective of this study was to evaluate ant diversity in areas with different land use histories ...

Ant assemblage (Hymenoptera: Formicidae) in three wind farms in the State of Paraná, Brazil

Braz. j. biol; 77 (1), 2017
Abstract The transformation of natural habitats into areas destined to agriculture or projects of energy production has generated a growing concern about the impact on biological diversity. Thus, this study evaluated the diversity of ants in agroecosystems in the area of direct influence of three wind fa...

Taxones superiores de hormigas como sustitutos de la riqueza de especies, en una cronosecuencia de bosques secundarios, bosque primario y sistemas agroforestales en la Amazonía Oriental, Brasil

Rev. biol. trop; 65 (1), 2017
ResumenLa deforestación es una de las principales causas de pérdida de biodiversidad en todo el mundo. Las hormigas son clave como ingenieras del ecosistema, por lo tanto, la pérdida de la diversidad de hormigas puede indicar la pérdida de funciones cruciales de los ecosistemas. El objetivo de este e...

Canopy cover negatively affects arboreal ant species richness in a tropical open habitat

Braz. j. biol; 76 (4), 2016
Abstract We tested the hypothesis of a negative relationship between vegetation characteristics and ant species richness in a Brazilian open vegetation habitat, called candeial. We set up arboreal pitfalls to sample arboreal ants and measured the following environmental variables, which were used as surr...

The diversity of ant communities (Hymenoptera: Formicidae) and their connections with other arthropods from three temperate forests of Central Mexico

Rev. biol. trop; 64 (2), 2016
AbstractAnts have been considered useful for bioindication because of their ecological characteristics. Nonetheless, among the characteristics of a bioindicator group, there must be a consistent and replicable response to disturbance. In this sense, divergent reactions have been found, even between taxon...

Can anthropic fires affect epigaeic and hypogaeic Cerrado ant (Hymenoptera: Formicidae) communities in the same way?

Rev. biol. trop; 64 (1), 2016
AbstractFire occurrences are a common perturbation in Cerrado ecosystems, and may differently impact the local biodiversity. Arthropods are one of the taxa affected by fires, and among them, ants are known as good bioindicators. We aimed to evaluate the effect of anthropic fires on epigaeic and hypogaeic...
