Study species. Atta cephalotes forms large colonies of strongly polymorphic workers that cultivate a food crop and maintain colony operations through division of labor. Worker size in A. cephalotes (head width 0.5-5.0 mm+) broadly correlates with task performance (reviewed in Muratore et al. 2022).Workers have been historically categorized as minims, medias, and majors according to body size. Cyperus digitatus var. khasianus (C. B. Clarke) J. Kern is often not recognised as a distinct taxon, but treated as a synonym of C. digitatus Roxb. Moreover, the recent World Checklist of Cyperaceae (Govaerts et al.2007) does not list this combination.However, an examination of specimens in the herbaria at BM and K has confirmed that it can, indeed, be treated as a distinct variety, following Abstract. Cephalotes varions (Smith) (Hymenoptera: Formicidae) recently was included on a list of adventive ants established in North America. Published and unpublished records of C. varions from >100 sites reveal that it has an apparently continuous distribution through the Bahamas, Cuba, and southern Florida. from publication: Geographic Distribution of Cephalotes varians (Hymenoptera: Formicidae) | Cephalotes varians (Smith) (Hymenoptera: Formicidae) recently was included on a list of adventive ants 1. Introduction. Immemorially, human societies have been using herbs and their products as sources of medicine, nutrition, and industrial applications [].As an example of the role of plant species in human life, in ancient Egypt, the first paper was made from papyrus (Cyperus papyrus L.), a species of the Cyperaceae family [].Cyperaceae includes grass-like monocots, comprising around 5600 Cephalotes varians has an apparently continuous distribution through the Bahamas, Cuba, and southern Florida.
