A Cytogenetic Approach to the Study of Neotropical Odontomachus and Anochetus Ants (Hymenoptera: Formicidae)
ABSTRACT Odontomachus (Latreille) and Anochetus (Mayr) (Hymenoptera: Formicidae: Ponerinae) are closely related pantropical genera of ponerine ants that share morphological and behavioralExpand

Cytogenetic data on six leafcutter ants of the genus Acromyrmex Mayr, 1865 (Hymenoptera, Formicidae, Myrmicinae): insights into chromosome evolution and taxonomic implications
Abstract Cytogenetic data for the genus Acromyrmex Mayr, 1865 are available, to date, for a few species from Brazil and Uruguay, which have uniform chromosome numbers (2n = 38). The recentExpand

Karyotype characterization of Trigona fulviventris Guérin, 1835 (Hymenoptera, Meliponini) by C banding and fluorochrome staining: report of a new chromosome number in the genus
Although many species of the genus Trigona have been taxonomically described, cytogenetic studies of these species are still rare. The aim of the present study was to obtain cytogenetic data byExpand

Comparative molecular cytogenetics in Melipona Illiger species (Hymenoptera, Apidae)
Cytogenetic studies in Melipona are scarce with only 24 species analyzed cytogenetically. Of these, six species had the rDNA sites physically mapped and characterized by Fluorescent in situExpand

Not endemic after all: Imparipecten Freeman, 1961 (Diptera: Chironomidae) described from the Neotropical Region.
Imparipecten, a previously monotypic genus, was considered endemic to Australia. Here, we report Imparipecten from the Neotropical region for the first time and describe Imparipecten sychnacanthusExpand

Numerical and structural chromosome variation in the swarm-founding wasp Metapolybia decorata Gribodo 1896 (Hymenoptera, Vespidae)
The Neotropical Polistinae wasps are diverse in taxonomy, social behavior, and nesting founding characteristics. Although some species in this group have been used as models for studies on wasp’sExpand

Occurrence of pre-nucleolar bodies and 45S rDNA location on the chromosomes of the ant Mycocepurus goeldii (Forel) (Formicidae, Myrmicinae, Attini).
The ant Mycocepurus goeldii (Forel) is known for having a relict karyotype with low chromosome number and the present study help the understanding of this ant cytogenetics by describing theExpand

Physical location of the carotenoid biosynthesis genes Psy and β-Lcy in Capsicum annuum (Solanaceae) using heterologous probes from Citrus sinensis (Rutaceae).
Carotenoids are responsible for a range of fruit colors in different hot pepper (Capsicum) varieties, from white to deep red. Color traits are genetically determined by three loci, Y, C1, and C2,Expand

Gyretes Brullé (Coleoptera: Gyrinidae) from Brazil: Morphology of eggs and early instars.
Taxonomic information regarding Gyrinidae is mostly based on adults, especially due to the difficulty in collecting immatures and assigning them to a particular species. Association between immaturesExpand

Leaf carbon assimilation and molecular phylogeny in Cattleya species (Orchidaceae).
We examined leaf CO(2) assimilation and how it varied among species within the orchid genus Cattleya. Measurements of CO(2) assimilation and maximum quantum yield of PS II (Fv/Fm) were made forExpand
