| En las zonas rurales de México, la hormiga "escamolera" (Liometopum apiculatum) es socioeconómicamente importante porque sus larvas, conocidas como "escamoles" se extraen de los hormigueros y son vendidos para el consumo humano. Sin embargo, la hormiga escamolera está siendo explotada de manera no sostenible y no existen estudios sobre el uso del hábitat por esta especie en el centro de México. Para identificar el uso del hábitat por la hormiga escamolera, durante la primavera-verano de 2012, se evaluaron catorce variables del hábitat en parcelas circulares de 20 m de diámetro, de 54 nidos de hormigas y de 162 parcelas seleccionadas al azar; asimismo, se estimó la densidad de nidos en sitios con tres niveles de perturbación del ecosistema. Asimismo, para... |

| The present study used the previously defined relationships among the snail-killing species of Sepedonea as the starting point for a cladistic biogeography analysis of endemic areas in the Neotropical region. The goal of the study was to use two different data sets to test the possible monophyly of two important biomes in the region: the Amazon and the Atlantic Forest. The possible historical significance of the arid biomes was also investigated. The study used Brooks Parsimony Analysis (Primary BPA). The area groups were based on previous biogeographical classifications of the Neotropial region. The analyses showed Amazonia to be non-monophyletic whereas the Atlantic forest was found to be a natural unit. The importance of including dry areas in the... |

| In rural areas of Mexico, the native "escamolera" ant (Liometopum apiculatum Mayr) is socioeconomically important. However, this ant is being exploited unsustainably, and studies of habitat of this species in central Mexico are nonexistent. During spring-summer 2012, fourteen habitat variables were evaluated, habitat use by the ant was identified and its nest density was estimated. Data were analyzed with stepwise logistic regression, correspondence analysis, Chi-square and simultaneous Bonferroni confidence intervals analyses, and the minimum Akaike Information Criteria. The variables that better described the presence of the ant were width of the agave pineapple, percentage of agaves infested with scale insects, woody plant-cacti-agave density, soil... |
