Genetic structure of sigmodontine rodents (Cricetidae) along an altitudinal gradient of the Atlantic Rain Forest in southern Brazil Genet. Mol. Biol.
Gonçalves,Gislene L.; Marinho,Jorge R.; Freitas,Thales R.O..
The population genetic structure of two sympatric species of sigmodontine rodents (Oligoryzomys nigripes and Euryoryzomys russatus) was examined for mitochondrial DNA (mtDNA) sequence haplotypes of the control region. Samples were taken from three localities in the Atlantic Rain Forest in southern Brazil, along an altitudinal gradient with different types of habitat. In both species there was no genetic structure throughout their distribution, although levels of genetic variability and gene flow were high.

Sequence variation in the melanocortin-1 receptor (MC1R) pigmentation gene and its role in the cryptic coloration of two South American sand lizards Genet. Mol. Biol.
Corso,Josmael; Gonçalves,Gislene L.; Freitas,Thales R.O. de.
In reptiles, dorsal body darkness often varies with substrate color or temperature environment, and is generally presumed to be an adaptation for crypsis or thermoregulation. However, the genetic basis of pigmentation is poorly known in this group. In this study we analyzed the coding region of the melanocortin-1-receptor (MC1R) gene, and therefore its role underlying the dorsal color variation in two sympatric species of sand lizards (Liolaemus) that inhabit the southeastern coast of South America: L. occipitalis and L. arambarensis. The first is light-colored and occupies aeolic pale sand dunes, while the second is brownish and lives in a darker sandy habitat. We sequenced 630 base pairs of MC1R in both species. In total, 12 nucleotide polymorphisms were...

A redescription of Antispastis clarkei Pastrana (Lepidoptera, Glyphipterigidae) immature stages, with notes on the life history and phylogenetic placement of the genus Rev. Bras. entomol.
Moreira,Gilson R.P.; Brito,Rosângela; Isaias,Rosy M.S.; Silveira Jr,JorgeL.; Gonçalves,Gislene L..
Abstract Antispastis Meyrick, 1926 is a poorly known genus of leaf-mining micromoths endemic to the Neotropics, with still uncertain taxonomic position within the Yponomeutoidea. In the present study, the egg, larva and pupa of A. clarkei Pastrana, previously known only from Argentina, are described and illustrated with the aid of optical and scanning electron microscopy. Data on life history, including histology of the mine, are also provided. Family placement of the genus is reassessed based on comparison of morphology and DNA sequences with closely related lineages. The larvae form blotch mines on the upper surface of Solanum L. (Solanaceae) leaves, feeding on palisade parenchyma in all instars. Pupation occurs outside the mine, in an inverted...

A new species of Leurocephala Davis & Mc Kay (Lepidoptera, Gracillariidae) from the Azapa Valley, northern Chilean Atacama Desert, with notes on life-history Rev. Bras. entomol.
Pereira,Cristiano M.; Silva,Denis S.; Gonçalves,Gislene L.; Vargas,Héctor A.; Moreira,Gilson R.P..
ABSTRACT The Neotropical micromoth genus Leurocephala Davis & Mc Kay, 2011 (Lepidoptera, Gracillariidae) was originally described to include only the type species, L. schinusae Davis & Mc Kay, 2011, whose leaf miner larvae are associated with Anacardiaceae in Argentina, Brazil and Paraguay. An integrative analysis including morphology, life history and DNA barcode sequences revealed that specimens collected on Schinus molle L. (Anacardiaceae) in the coastal valleys of the Atacama Desert of northern Chile belong to a second species of this formerly monotypic genus. Adults of Leurocephala chilensis Vargas & Moreira sp. nov. are herein described and illustrated in association with the immature stages and life history, and corresponding...

Extant diversity and estimated number of Gracillariidae (Lepidoptera) species yet to be discovered in the Neotropical region Rev. Bras. entomol.
Brito,Rosângela; Prins,Jurate De; Prins,Willy De; Mielke,Olaf H.H.; Gonçalves,Gislene L.; Moreira,Gilson R.P..
ABSTRACT Gracillariidae (Lepidoptera) are commonly known by the leaf miner habit found in the larval stage of most species. By using worldwide, public databases on species diversity and DNA sequences available for extant gracillariid species, we determined changes in the rate of taxonomic species descriptions through time, mapped their spatial distributions, examined their phylogenetic diversification, and estimated the number of species yet to be described for the family in the Neotropics. We recovered 185 species, a number that is smaller than that found in any other biogeographic region. However, it was estimated that at least 3875 additional species remain to be described in the region. Phylogenetic diversification showed a pattern of expanding...

A new cecidogenous species of many-plumed moth (Alucitidae) associated with Cordiera A. Rich. ex DC. (Rubiaceae) in the Brazilian Cerrado Rev. Bras. Zool.
Moreira,Gilson R.P.; Pereira,Cristiano M.; Becker,Vitor O.; Specht,Alexandre; Gonçalves,Gislene L..
ABSTRACT Larvae of many-plumed moths (Alucitidae), especially in the world-wide genus Alucita Linnaeus, 1758 are known as borers or gall-inducers on flowers, fruits and shoots of a few dicotyledonous families, including Bignoniaceae, Caprifoliaceae and Rubiaceae. However, there is no study available on the biology of the monotypic, Neotropical genus Prymnotomis Meyrick, 1931 except for its original description that was based on a single male, the holotype of Prymnotomis crypsicroca Meyrick, 1931 from Espirito Santo, Brazil. We describe here a second species for this genus, Prymnotomis cecidicola sp. nov. whose larvae induce galls on Cordiera elliptica (Cham.) Kuntze (Rubiaceae), a dioecious plant with dimorphic inflorescences found in the Brazilian...

Bark consumption by the spiny rat Euryzygomatomys spinosus (G. Fischer) (Echimyidae) on a Pinus taeda Linnaeus (Pinaceae) plantation in South Brazil Zoologia
Gonçalves,Gislene L.; Faria-Correa,Mariana A.; Cunha,Adriano S.; Freitas,Thales R. O..
Feeding damage caused by Euryzygomatomys spinosus (G. Fischer, 1814) (Echimyidae) is documented for a Pinus taeda Linnaeus (Pinaceae) plantation located in Cambará do Sul, Rio Grande do Sul State, Brazil. Under laboratory conditions, feeding acceptance of P. taeda trunk sections was tested with positive results for E. spinosus, but not for other three co-occurring sigmodontine rodents: Akodon montensis Thomas, 1913, Oligoryzomys nigripes (Olfers, 1818) and Delomys dorsalis (Hensel, 1872).
