Diversidad de escarabajos coprófagos (Coleoptera: Scarabaeidae) en tres zonas urbanizadas del Caribe colombiano / Diversity of dung beetles (Coleoptera: Scarabaeidae) in three urban areas from Colombian Caribbean

Resumen En el presente trabajo se estudia la diversidad de escarabajos coprófagos en tres zonas urbanizadas del departamento de Sucre, Colombia, cada una con características ecológicas distintas. Los individuos fueron capturados con trampas de caída cebadas. Se analizaron el esfuerzo de muestreo, las curvas de rango-abundancia y los índices de diversidad alfa y beta. Se capturaron 710 individuos, agrupados en nueve géneros y 13 especies. El análisis de completitud arrojó valores por encima del 97%. El ensamble más diverso en cualquiera de los tres órdenes de "q" se encontró en la zona que alberga edificaciones, jardines y un parche de bosque de vegetación secundaria, seguido por una zona de pastizales, con pocas edificaciones; el ensamble de menor diversidad correspondió a la zona rodeada de edificaciones y con escasa cobertura vegetal. El índice de Sorensen-Dice arrojó una similitud total entre las tres zonas del 38%. Las curvas de rango-abundancia mostraron mayor equidad de especies en la zona más diversa. Los resultados indicaron que la composición del ensamble de escarabajos depende de las condiciones ambientales y el grado de urbanización. Así mismo, se evidenció que algunas especies pueden tener alta adaptabilidad y que algunas de ellas corren el riesgo potencial de presentar eventos de extinción local.

Abstract In this paper, diversity and composition of dung beetles assemblage was study in three urbanized areas with different ecological characteristics from Sucre department , Colombia. Individuals were captured with baited pitfall traps. Sampling effort, range-abundance curves, alpha and beta diversity indices were estimated and compared among the sites. Seven hundred ten individuals grouped into nine genera and 13 species were recorded. The completeness analysis yielded values above 97%. The most diverse assemblage in any of the three orders of "q" was found in the site with a mixture of buildings, gardens, and a patch of secondary vegetation forest, followed by the site with few facilities and open green spaces, and the least diverse site corresponded to the area surrounded by buildings with little vegetation cover. Sorensen-Dice index similarity among the three sites was 38%. The range-abundance curves showed higher species equitability in the most diverse site. The results show that the beetle assemblage composition depends on environmental conditions and the degree of urbanization. It was also evident that some species have high adaptability to urban spaces and others are potentially at risk of local extinction events.

Genetic analysis of an insular population of Sapajus nigritus (Primates: Cebidae) in Rio de Janeiro state, Brazil.

The black-horned capuchin (Sapajus nigritus) is a neotropical primate with wide distribution from southeastern Brazil to northeastern Argentina. Although this species has been described with coat pattern variation, even with intrapopulational differences, and characterized as having the greatest genetic diversity among Sapajus species, there are still few studies on natural populations that contribute to the knowledge of this intraspecific variability. We examined individuals from an as yet unstudied population of Ilha da Marambaia, Rio de Janeiro (RJ) state, Brazil, compared with published data for S. nigritus. We sought to confirm the species through phenotypic and genetic characterization using C-banding and fluorescence in situ hybridization with #11qHe+/21WCP probes for chromosomal constitutive heterochromatin (He+) patterns, and cytochrome c oxidase I and II gene sequences for phylogenetic analysis. The coat presented two color patterns, varying from brown to blackish on the body, yellow to brown on the chest, and white to yellow on the face, besides the presence and shape of the tufts on the head, corresponding to S. nigritus. He+ was identified in pairs 4, 12, 13 and 17, and less consistently in pairs 6, 19 and 21, already described for this species. While most Sapajus species have a large He+ block, here pair 11 was identified without extracentromeric He+, the same as reported for S. nigritus from Argentina. Molecular analysis showed divergence of this population from other S. nigritus sequences, reinforcing a trend already demonstrated when samples from RJ are compared with the rest of the distribution, which may represent an evolutionary deviation.

A novel Betacoronavirus characterised in collared peccaries from the Rio de Janeiro Zoo (Brazil) killed by unknown disease.

In an enclosure with nine collared peccaries (Pecari tajacu) from the Rio de Janeiro city Zoo, Brazil, one specimen was found dead and two others developed prostration, apathy and dehydration, resulting on its death. Necropsy of two animals pointed to pulmonary and renal damage. Histological examination revealed vasculitis in spleen from both P. tajacu, suggesting a systemic viral infection. Lungs from one specimen showed fibrinoid vasculitis, alveolar damage with hyaline membrane, and interstitial lymphocytes infiltration. Virome analysis in anal wash samples from the latter two animals revealed a new type of Betacoronavirus, lineage A, provisionally named Ptajacu-CoV.

Molecular and morphometric identification of Trypanosoma (Megatrypanum) minasense in blood samples of marmosets (Callithrix: Callithrichidae) from the city of Rio de Janeiro, Brazil.

Callithrix jacchus and C. penicillata marmosets are invasive to the state of Rio de Janeiro, Brazil, threatening the native and vulnerable C. aurita. Both invasive species can be hosts of Trypanosoma cruzi, T. minasense, T. rangeli and T. devei. We aim to investigate the occurrence of trypanosomatids in Callithrix sp. from Jardim Botânico do Rio de Janeiro, located in a central and populous area of the city. Fifteen marmosets were captured. Blood samples were collected for light microscopy and molecular genetics analysis. Parasites morphometric values were evaluated for species identification. DNA was extracted from blood samples by phenol-chloroform method, for partial amplification of the 18S rRNA gene. PCR products were sequenced and aligned using BLAST®. A maximum likelihood phylogenetic tree was constructed to analyze the proximity between the observed sequences. By light microscopy, trypomastigotes were detected in five of the fifteen marmosets. Morphometric measurements and size polymorphism corresponded to those previously described for T. minasense. The DNA sequences of approximately 600 base pairs of the 18S rRNA gene were obtained for three samples with 99% identity with T. minasense sequence, forming a cluster in the phylogenetic tree and corroborating morphometric analysis. Trypanosoma minasense is a highly specific parasite to non-human primates considered as non-pathogenic. There is no evidence of infection in humans and these parasite findings from invasive marmosets do not support additional risks for the native species.

Neotropical carnivores: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non‐detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non‐governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peerreviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non‐detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio‐temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other largescale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used. We also request that users inform us of how they intend to use the data.

Marinoni Martins (1978) proposed Anasillus for a single species, A. crinitus Marinoni Martins, 1978, based on a single male specimen from Peru, and until now, the female remained unknown. Herein, the female of this species is described and illustrated for the first time, and its geographical distribution is expanded to Colombia. Additionally, the geographical distribution of seven species of Cerambycidae is expanded to Colombia: Coleoxestia vittata (Thomson, 1861); Sphallenopsis pilosovittata (Bates, 1872); Aneflus (Protaneflus) minutivestis Chemsak Linsley, 1963; Mallocera amazonica Bates, 1870; Compsibidion charile (Bates, 1870); Alcidion sulphurifer (White, 1855); and Acanthoderes (Acanthoderes) ariasi Chemsak Hovore, 2002.

A new species of Eurysthea Thomson, 1861 (Coleoptera: Cerambycidae) from Colombia.

Eurysthea Thomson, 1861 is currently composed of 23 species (Botero Santos-Silva 2017; Monné 2018). Its distribution extends from Nicaragua to Argentina, with a certain preference toward the sub-Andean forest areas and the Atlantic forest (Martins 2005; Monné 2018). Currently, six species are recorded for Colombia (Botero Santos-Silva 2017; Monné 2018): E. antonkozlovi Botero Santos-Silva, 2017; E. barsevskisi Botero Santos-Silva, 2017; E. cribripennis Bates, 1885; E. rotundicollis (Martins, 1995); E. sordida (Erichson, 1847); and E. tatianakozlovae Botero Santos-Silva, 2017.

Cytogenetics and Molecular Genetic Analysis of Chimerism in Marmosets (Callithrix: Primates).

The birth of fraternal twins is a characteristic frequently observed in callitrichids. Cytogenetic studies have demonstrated hematopoietic chimerism in marmosets with the occurrence of two cell lines 2n=46,XX/46,XY in females and males co-twins, without phenotypic changes. Amplification by PCR have also been used to verify the presence of the SRY gene in female chimaeras. Our aim was to verify the occurrence of chimerism in Callithrix sp. individuals considered as hybrids according to their intermediate phenotypes between C. jacchus and C. penicillata. Blood samples from 37 Callithrix sp. individuals were collected. Hematopoietic chimerism 2n=46,XX/46,XY was detected by cytogenetic analysis in five individuals, three males and two females. A fragment of approximately 200bp of the SRY gene was amplified in seven females with normal external genitalia. The percentage of 32% of chimeric individuals detected in the present study is similar to that observed for pure specimens of Callithrix. These data suggests that hybridization probably does not interfere with the occurrence of twin gestation, nor of chimerism. Although cytogenetics is the main tool to identify the two cell lineages present in cases of chimerism, the amplification of the SRY gene by PCR has proved to be more efficient to identify the Y chromosome in cases of chimeric female marmoset.

The composition of milk from free-living common marmosets (Callithrix jacchus) in Brazil.

Common marmosets, one of the smallest anthropoid primates, have a relatively high reproductive rate, capable of producing twins or triplets twice per year. Growth and development of infants is relatively rapid, and lactation is relatively short at less than 3 months. Although mean values for the proximate composition (dry matter, protein, fat and sugar) of captive common marmoset milks fall within anthropoid norms, composition is highly variable among individual samples, with concentrations of milk fat ranging from below 1 to over 10%. To examine the extent to which this variation might be a consequence of captive conditions, we collected milk samples from wild common marmosets freely living on a farm in the state of Rio de Janeiro, Brazil. The proximate composition of the milk samples was assayed using identical techniques as used for the captive marmoset milks. The composition of the milk of wild common marmosets was also variable, but tended to be lower in dry matter, fat, protein and gross energy, and higher in sugar than milks from captive animals. Interestingly, the percentage of estimated gross energy from the protein fraction of the milks was relatively constant in both wild and captive marmosets and did not differ between wild and captive animals: 1 kcal of common marmoset milk contains on average (+/-SEM) 0.035+/-.001 g of protein regardless of the gross energy content of the milk or whether the milk was from a wild or captive animal. In contrast, in 1 kcal of low-energy milks, the amount of sugar was significantly higher and the amount of fat significantly lower than in 1 kcal of high-energy milks. Thus, common marmoset milk exhibits axes of variability (especially fat concentration) as well as a significant stability in the relative amount of protein.

Parasitos em sagüi-de-tufo-branco (Callithrix jacchus) no Rio de Janeiro / Parasites in commn marmoset (Callithrix jacchus) in Rio de Janeiro

O contato crescente entre os animais selvagens com os domésticos e os seres humanos tem possibilitado o aumento do trânsito de parasitos entre as espécies. A cidade do Rio de Janeiro, por sua geografia e forma de desenvolvimento urbano, somado a presença do Parque Nacional da Tijuca (PNT) no meio da área urbana, estimula hábitos em seus habitantes e possibilita o contato das pessoas com áreas naturais de uma forma mais ampla do que em outras grandes cidades. Este Parque abriga uma série de espécies autóctones e exóticas, como o sagüi-de-tufo-branco (Callithrix jacchus), originário da região nordeste. Os primatas da família Cebidae são considerados pela Fundação Nacional de Saúde como hospedeiros ou reservatórios de parasitos com potencial risco biológico, merecendo atenção da Coordenação de Vigilância e Controle dos Fatores de Risco Biológico (Cofab). O objetivo desta pesquisa foi realizar um estudo das infecções por fungos, bactérias e helmintos em Callithric jacchus, que possam transitar, por intermédios desta espécie para os seres humanos. Escolhendo-se áreas do interior do PNT, áreas urbanas e animais provenientes de cativeiro, foram realizadas comparações para observação dos diferentes parasitos circulantes. 65 espécimes foram analisados, sendo 34 do Parque Nacional da Tijuca, 11, de áreas urbanas e 20 provenientes de cativeiro, por meio de exames clínicos e laboratoriais, para pesquisa hemoparasitos, levantamento de flora bacteriana e fúngica. 27,7 % dos animais do estudo apresentaram problemas dentários e no PNT foi diagnosticadas microfilárias em 29,4 %, Trypanosoma minasense em 47 % dos animais e T. devei em 5,9 %. Somente foram encontrados espécies de fungos saprófitas, porém a flora bacteriana, além das saprófitas apresentou Campylobacter jejuni tipos I e II e Salmonela newland, como espécies que merecem atenção.

The increased contact among wildlife with domestic animals and human beings has been improving the crescent transit of parasites between species. Because of its geography, urban development, and the presence of Tijuca National Park (PNT) in the middle of urban area, the city of Rio de Janeirostimulates the inhabitants to a bigger contact with natural areas than in other big cities. This Park protects a series of autoctonous and exotic species as the common marmoset (Callithrix jacchus), from Northeastern region. Primates from the family Cebidae are considered hosts and reservoirs of zoonoticparasites by the National Health Foundation, deserving, special attention from Biological Risk Factors Control and Surveillance Coordination (Cofab). The objective of this research was study fungi, bacterial and helminth infection of Callithric jacchus, that can transit by them, to humans. Comparisons were made between PNTs core forested areas, urban areas and captive animals. Clinical and laboratorial examination, including hemoparasite, bacterial and fungi search were developed in 65specimens, 34 from PNT, 11 from urban areas and 20 from captivity. 27,7% had teeth problems, and in PNT 29,4% had microfilarids, 47% Trypanosoma minasense and 5,9% T. devei.

Behavioral and ecological interactions between reintroduced golden lion tamarins ( Leontopithecus rosalia Linnaeus, 1766 ) and introduced marmosets ( Callithrix spp, Linnaeus, 1758 ) in Brazil's Atlantic Coast forest fragments

Callithrix jacchus e spp (micos estrela) tem sido introduzido no estado do Rio de Janeiro em áreas designadas para a reintrodução do Leontopithecus rosalia (mico leão dourado). Os objetivos deste estudo foram estimar a população de sagüis em dois fragmentos particulares, e caracterizar a interação entre as espécies. A densidade de sagüis (0.09 a/ha) foi maior que a de mico-leão (0.06 a/ha). O grau de associação entre mico-leão e o sagüi variou entre grupos e estações do ano (inverno= 61%, verão =35%). Foram observados sinais de competição durante o inverno quando a presença do mico estrela está associada a mudanças no forrageio do mico-leão e aumento de comportamentos territoriais. No verão, sinais de benefícios foram uma diminuição da vigilância por parte dos adultos de micos leões. Além disso, os micos leões foram observados se alimentando de goma proveniente dos buracos feitos pelos micos estrela. Estes resultados sugerem que o mico estrela é uma ameaça para a conservação do mico-leão, no entanto.

Tratamento do carcinoma renal metastático / Treatment of the metastic renal cell carcinoma

O carcinoma de células renais (COR) é a sétíma principal causa de câncer, respondendo por 3por cento dos tumores malignos no homem. Em um terço dos casos se apresenta como doença avançada e até 50por cento dos pacientes tratados cirurgicamente terão recidiva tumoral Acomete os homens duas vezez mais frequentemente que as mulheres e é mais comum entre a quinta e a sétima década de vida. O CCR teve sua incidência aumentada a partir da década de 70 devido ao uso rotineiro do ultra-som e aumento dos fatores de risco na população como fumo, obesidade e hipertensão. Pacientes com CCR metastático não tratados têm uma sobrevida média de seis a dez meses e apenas 10por cento a 20por cento estarão vivos após dois anos. Atualmente, com um melhor estudo da biologia e história natural do CCR, muitos avanços têm ocorrido nas áreas da genética molecular e ímunologia. Os autores fazem uma revisão das atuais modalidades terapêuticas do CCR avançado.

Serial clinical, colpo-cytological and endocrinological evaluations of Cerdocyon thous bitches from the Rio de Janeiro zoo

Serial clinical, colpo-cytological and endocrinological examinations of two five-year-old females of the crab-eating dog (Cerdocyon thous), from the RIOZOO Foundation in the State of Rio de Janeiro - Brazil, were carried out over a 10-month period. Clinically healthy animals were kept in sand substratum enclosures, located 500m apart from each other. They were each housed with two males. The colpo-cytological technique employed for Cerdocyon thous used methods similar to those developed for domestic bitches. Unlike domestic dogs, blood cells were absent in all phases of the estrus cycle, including the pro-estrus phase. Differentiation of each type of vaginal cells during the estrus cycle phases in this species follows the same patterns shown by domestic bitches. The estradiol and progesterone levels were similar to those occurring in domestic bitches. The progesterone levels reach their maximum (46 ng/ml) around the 10th day of pregnancy. The estradiol analysis demonstrated that, although levels of this hormone could be high at various times throughout the year, mating actually occurs in late winter and in spring. It was impossible to evaluate whether males and females kept in close proximity throughout the entire year would stimulate the production of estradiol, resulting in what would be considered a captivity artifice

Objetivo: investigar a eficácia e a tolerabilidade do extrato lipoesterólico de Serenoa repens (LSESr) no tratamento da Hiperplasia Prostática Benigna (HPB). Métodos: estudo multicêntrico prospectivo, aberto, näo-controlado, realizado em 17 clínicas urológicas. Estudados 142 pacientes ambulatoriais com idade acima dos 50 anos e HPB sintomática, Pontuaçäo Internacional de Sintomas Prostáticos (I-PSS) maior ou igual a 8 na escala da OMS e taxa máxima de fluxo urinário menor ou igual a 12 ml/s para um volume urinário maior ou igual a 150 ml. Os pacientes receberam uma capsula de 160 mg do extrato lipidoesterólico de Serenoa repens duas vezes ao dia durante três meses. Avaliados I_PSS, índice de qualidade de vida (QV), urofluxometria e dosagem do antígeno prostático específico (PSA) sérico no início e ao término do estudo. Os efeitos colaterais foram registrados sistematicamente. A análise estatística foi realizada, utilizando-se um teste "t" pareado para avaliar a evoluçäo do I-PSS e da urofluxometria em D90 comparado ao D0. Obsevadas alteraçöes significativas nos parâmetros, nenhuma reaçäo adversa séria foi observada, outras reaçöes adversas leves e passageiras foram registradas em 10,56 porcento dos casos, principalmente gastrointestinais. Somente um paciente abandonou o tratamento devido à reaçäo adversa gastrointestinal. Näo houve diferença estatísticamente significante entre a média basal e final dos valores do PSA. Neste estudo o extrato lipidoesterólico da Serenoa repens demonstrou ser uma terapia medicamentosa da HPB com boa eficácia na sintomatologia e nas aferiçöes objetivas, além de ter sido muito bem tolerado pela grande maioria dos pacientes.(au)
