The taxonomy and phylogenetics of Neotropical deer have been mostly based on morphological criteria and needs a critical revision on the basis of new molecular and cytogenetic markers. In this study, we used the variation in the sequence, copy number, and chromosome localization of satellite I-IV DNA to evaluate evolutionary relationships among eight Neotropical deer species. Using FISH with satI-IV probes derived from Mazama gouazoubira, we proved the presence of satellite DNA blocks in peri/centromeric regions of all analyzed deer. Satellite DNA was also detected in the interstitial chromosome regions of species of the genus Mazama with highly reduced chromosome numbers. In contrast to Blastocerus dichotomus, Ozotoceros bezoarticus, and Odocoileus virginianus, Mazama species showed high abundance of satIV DNA by FISH. The phylogenetic analysis of the satellite DNA showed close relationships between O. bezoarticus and B. dichotomus. Furthermore, the Neotropical and Nearctic populations of O. virginianus formed a single clade. However, the satellite DNA phylogeny did not allow resolving the relationships within the genus Mazama. The high abundance of the satellite DNA in centromeres probably contributes to the formation of chromosomal rearrangements, thus leading to a fast and ongoing speciation in this genus, which has not yet been reflected in the satellite DNA sequence diversification.

Context Polygynous deer rut vocalisations have been found to be highly conspicuous, typical of the species and important in sexual selection. Information about vocalisations is not available for Neotropical species (subfamily Odocoileinae). Aims The objective was to record courtship vocalisations from all Neotropical deer available, looking for differences among species useful for taxonomic identification, characterise the vocalisations according to acoustic parameters and to try to determine functions. Methods Four species of brocket deer (red, Mazama americana (n = 9); grey, M. gouazoubira (n = 7); Amazonian brown, M. nemorivaga (n = 3); Brazilian dwarf, M. nana (n = 1)), and one individual each of marsh (Blastocerus dichotomus), white-tailed (Odocoileus virginianus) and taruca (Hippocamellus antisensis) deer were recorded in captivity at two institutions, in conditions of courtship or human interaction. The acoustic analysis was performed with Praat. Data from the first three species of Mazama were analysed statistically with a multilevel model with two layers. Key results In the context of courting either females or humans, male deer produced low-intensity, short-duration (0.1–0.3 s) bleats with fundamental frequencies (F0) between 100 and 400 Hz; calls were similar among species. The duration of these calls for Amazonian brown brocket males was significantly longer than for males of the other two species. Females of two species had longer-duration calls than did males, in friendly interactions with humans. F0 differences among species for both friendly and courtship calls were almost significant for males of M. gouazoubira. Individual differences were highly significant for both duration and mean F0. Mean F0 for courtship calls of adult males was not correlated with body size in six of the seven species, in contrast to the theory of acoustic allometry. Conclusions The production of male courtship bleats is probably a basic feature of Odocoiline deer and is probably important in sexual selection and female choice. The differences from one species to another are not sufficient for taxonomic use but may be incipient isolating mechanisms between grey and Amazonian brown brocket deer. Implications Studies of deer vocalisations have shown their importance in sexual selection and their incredible variety in closely related species and subspecies, but they have dealt mainly with Old World deer. This study fills a gap in our knowledge, as the first on Neotropical deer, which constitute six genera and 17 species and are widely distributed in the Americas. These data are important for future studies on the function and phylogeny of deer vocalisations.

Dentre as inúmeras informações possíveis de se obter a partir da análise de artefatos ósseos, uma delas é a identificação das espécies e partes anatômicas utilizadas para a confecção desses artefatos. No território brasileiro, quatro espécies de cervídeos são comumente encontradas nas regiões sul e sudeste: Mazama americana, Mazama gouazoubira, Ozotoceros bezoarticus e Blastocerus dichotomus. Ao longo do Holoceno, ossos e galhadas dessas espécies de cervídeos foram utilizados no lascamento lítico, na produção de pontas ósseas e espátulas, entre outros artefatos. Estudos preliminares dos artefatos ósseos recuperados de três sítios arqueológicos de grupos caçadores-coletores do sudeste e sul do Brasil - sítio Lapa do Santo (MG), sítio Tunas (PR), e sítio Garivaldino (RS) - demonstram uma preferência por ossos de cervídeos para a confecção desses artefatos.

Se analiza la explotación de ungulados por parte de los grupos cazadores-recolectores que ocuparon el sector centro-oriental de la región Pampeana durante la fase final del Holoceno tardío (<2000 años AP). Para ello, consideramos las características eto-ecológicas de los principales taxa explotados (Lama guanicoe, Blastocerus dichotomus y Ozotoceros bezoarticus) y comparamos la información arqueofaunística procedente de dos sitios arqueológicos situados en dos de las unidades del paisaje que integran la región bajo estudio. A partir de los resultados obtenidos, mediante la aplicación de diferentes índices, se postulan distintas hipótesis con el fin de establecer y discutir similitudes y diferencias relacionadas con la importancia económica que adquirieron dichas presas y las modalidades utilizadas para su procesamiento y consumo.

El sitio arqueológico Cerro Tapera Vázquez (CTV) se encuentra dentro del Parque Nacional Pre-Delta, en el ambiente insular del río Paraná. Dos dataciones radiocarbónicas sobre restos de carbón vegetal ubican la ocupación humana en torno a los 600 años radiocarbónicos AP. En este artículo se presentan nuevos resultados obtenidos a partir del reanálisis del conjunto faunístico de este sitio arqueológico. Se identificaron diferentes especies de mamíferos, las cuales incluyen cérvidos (Blastocerus dichotomus, Ozotoceros bezoarticus), carnívoros (Leopardus geoffroyi, Lycalopex gymnocercus) y roedores (Myocastor coypus, Cavia aperea, Hydrochoerus hydrochaeris). Además, en menor medida, se identificaron algunos restos de aves (Podiceps major), peces (Pimelodus sp., Doradidae) y moluscos de agua dulce. La principal presa explotada fue el coipo (Myocastor coypus). Por otra parte, la presencia de otros recursos acuáticos y terrestres probablemente se deba a la caza ocasional (e.g. Leopardus geoffroyi) o a su incorporación natural al depósito (e.g. Cavia aperea).

ABSTRACT The aim of this study was to establish normal baseline ERG values of 23 anesthetized deer belonging to 8 neotropical species (Mazama americana, Mazama nemorivaga, Mazama gouazoubira, Mazama nana, Mazama bororo, Ozotocerus bezoarticus, Odocoileus virginianus and Blastocerus dichotomus). Only right eyes were studied. Chemical restraint was performed using xylazine associated with ketamine, IM, for M. americana, M. gouazoubira, M. nemorivaga, M. nana, M. bororo, O. bezoarticus and O. virginianus. A combination of tiletamine/zolazepam diluted in xylazine 2% was used for B. dichotomus individuals. After 20min of dark adaptation, electroretinograms were obtained using a handheld electroretinography (ERG) machine using the QuickRetCheck Protocol at three different light intensities: 0.01cd.s/m2, 3cd.s/m2, and 10cd.s/m2. After light adaptation, photopic phase was recorded. A-wave amplitude recorded during pattern mixed rod/cone response in M. americana was significantly lower when compared to B. dichotomus. No other differences were observed between the species studied. ERG in Neotropical deer is applicable using a portable ERG system and did not show differences among species in relation to the retinal response at different light intensities. Therefore, the lifestyle of the species is more dictated by the selection pressure of the environment than by physiological factors.

A large proportion of the genomes of grasses is comprised of tandem repeats (TRs), which include satellite DNA. A mini-satellite DNA sequence with a length of 44 bp, named Ta-3A1, was found to be highly accumulated in wheat genome, as revealed by a comprehensive sequence analysis. The physical distribution of Ta-3A1 in chromosomes 3A, 5A, 5B, 5D, and 7A of wheat was confirmed by nondenaturing fluorescence in situ hybridization (ND-FISH) after labeling the oligonucleotide probe. The analysis of monomer variants indicated that rapid sequence amplification of Ta-3A1 occurred first on chromosomes of linkage group 5, then groups 3 and 7. Comparative ND-FISH analysis suggested that rapid changes occurred in copy number and chromosomal locations of Ta-3A1 among the different species in the tribe Triticeae, which may have been associated with chromosomal rearrangements during speciation and polyploidization. The labeling and subsequent use of Ta-3A1 by ND-FISH may assist in the precise identification and documentation of novel wheat germplasm engineered by chromosome manipulation.
