Spatially Coherent Tip-Enhanced Raman Spectroscopy Measurements of Electron-Phonon Interaction in a Graphene Device.

Coherence length (Lc) of the Raman scattering process in graphene as a function of Fermi energy is obtained with spatially coherent tip-enhanced Raman spectroscopy. Lc decreases when the Fermi energy is moved into the neutrality point, consistent with the concept of the Kohn anomaly within a ballistic transport regime. Since the Raman scattering involves electrons and phonons, the observed results can be rationalized either as due to unusually large variation of the longitudinal optical phonon group velocity vg, reaching twice the value for the longitudinal acoustic phonon, or due to changes in the electron energy uncertainty, both properties being important for optical and transport phenomena that might not be observable by any other technique.

Participação nas aulas de Educação Física em Pernambuco: uma análise de tendência temporal / Participation in Physical Education classes in Pernambuco: a temporal trend analysis

O objetivo do estudo foi analisar a tendência temporal e fatores associados à participação nas aulas de educação física de estudantes de Pernambuco. Estudo de tendência temporal composto por três levantamentos de abrangência estadual. Foram entrevistados 4.207 estudantes em 2006, 6.264 em 2011 e 6.002 em 2016, por meio do questionário "Global School-based Student Health Survey" (GSHS). O desfecho foi a participação nas aulas de Educação Física e as exposições foram as informações sociodemográficas. A análise bivariada foi realizada mediante teste Qui-quadrado e as análises multivariadas por regressão logística binária. Observou-se um aumento na prevalência de participação nas aulas de Educação Física (2006: 35%, 2011: 74% e 2016: 81,2%) destacando o aumento significativo no sexo masculino Δ% (2006-2016) = 123,5%. Ser do sexo masculino, estudar no período integral e ser filho de mães que estudaram, independente do tempo de estudo foi associado a maior participação nas aulas de educação física, assim como residir nas regiões do Agreste, Sertão e Sertão do São Francisco. Apesar do aumento na participação nas aulas de Educação Física em Pernambuco, a garantia deste componente curricular deve ser fortalecida, levando em consideração os grupos de risco para que aumente a participação nas aulas desses grupos

The aim of the study was to analyze the temporal trend and factors associated with participation in physical education classes in Pernambuco. The temporal trend study was composed of three surveys. A total of 4,207 students were interviewed in 2006, 6,264 in 2011 and 6,002 in 2016, using the "Global School-based Stu-dent Health Survey" (GSHS) questionnaire. The outcome was participation in Physical Education classes and the independent variables were sociodemographic information. The bivariate analysis was performed using the chi-square test and the multivariate analysis using binary logistic regression. There was an increase in the prevalence of participation in Physical Education classes (2006: 35%, 2011: 74% and 2016: 81.2%), highlighting the significant increase in males Δ% (2006-2016) = 123.5%. Male, studying full-time and being the son of mothers who studied was associated with greater participation in physical education classes, as well as living in the regions of Agreste, Sertão and Sertão do São Francisco. Despite the increase in par-ticipation in Physical Education classes in Pernambuco, the guarantee of this curricular component must be strengthened, considering risk groups in order to increase participation in classes for these groups

Endoparasites of household and shelter cats in the city of Rio de Janeiro, Brazil.

Endoparasitic infections are associated with morbidity in cats. This study aimed to investigate the occurrence of endoparasites among cats of different life stages in the city of Rio de Janeiro, Brazil. The samples were analyzed individually by macroscopic exploration for proglottids and centrifugal-flotation. Stool samples were obtained from household cats (n = 57) and shelter cats (n = 336). Endoparasites were detected in 50.64% of the samples. Among household and shelter cats, 21.05% and 55.66% were infected with endoparasites, respectively. In household cats, the most prevalent endoparasites were Ancylostoma spp. (in 25.0%) and Strongyloides spp. (in 25.0%), followed by Toxocara spp. (in 16.67%), Dipylidium caninum (in 16.67%), Cystoisospora spp. (in 8.33%), and Uncinaria spp. + Ancylostoma spp. (in 8.33%). In shelter cats, the most prevalent endoparasite was Ancylostoma spp. (in 29.41%), followed by Cystoisospora spp. (in 26.20%) and Toxocara spp. (in 16.58%), as well as Cystoisospora spp. + Toxocara spp. (in 8.02%); Ancylostoma spp. + Toxocara spp. (in 11.76%); Cystoisospora spp. + Ancylostoma spp. (in 3.74%); Cystoisospora spp. + Toxocara spp. + Ancylostoma spp. (in 3.21%); and Dipylidium caninum + Ancylostoma spp. (in 0.53%). Endoparasitic infections in cats underscore the need for preventive veterinary care and routine coproparasitologic tests.

Resumo Endoparasitoses estão associadas à morbidade em gatos. Este estudo objetivou investigar a ocorrência de endoparasitos em gatos de diversas faixas etárias, na cidade do Rio de Janeiro. As amostras passaram por exploração macroscópica à procura de proglotes de cestódeos e analisadas individualmente por centrífugo-flutuação. Assim, amostras fecais foram obtidas de gatos domiciliados (n = 57) e de abrigos (n = 336). Endoparasitos foram detectados em 50,64% das amostras fecais. Nos gatos domiciliados e de abrigos, 21,05% e 55,66% estavam infectados por endoparasitos, respectivamente. Ancylostoma spp. (25%) e Strongyloides spp. (25%) foram os helmintos mais prevalentes encontrados nas amostras de fezes dos gatos domiciliados, seguido por Toxocara spp. (16,67%), Dypilidium caninum (16,67%), Cystoisospora spp. (8,33%) e a associação de Uncinaria spp. e Ancylostoma spp. (8,33%). Entre os gatos dos abrigos, Ancylostoma spp. estavam presentes em 29,41% das amostras, seguidos por Cystoisospora spp. (26,20%), Toxocara spp. (16,58%) e as associações de parasitos Cystoisospora spp. + Toxocara spp. (8,02%), Ancylostoma spp. + Toxocara spp. (11,76%), Cystoisospora spp. + Ancylostoma spp (3,74%), Cystoisospora spp. + Toxocaraspp. + Ancylostoma spp. (3,21%) e Dipylidium caninum + Ancylostoma spp. (0,53%). Cystoisospora spp. foi o único protozoário encontrado. A presença de endoparasitos reforça a necessidade de cuidados veterinários preventivos e testes coproparasitológicos de rotina para evitar sua disseminação.

Fear or Humour in anti-smoking campaigns? Impact on perceived effectiveness and support for tobacco control Policies / Medo ou Humor em campanhas antitabágicas? O impacto na perceção de eficácia e apoio a políticas antitabágicas

Abstract Several anti-smoking campaigns have been used for decades to reduce smoking consumption. However, so far, there is no consensus regarding the effectiveness of inducing distinct emotions in reducing smoke consumption. This study tested the effects of two types of anti-smoking ads, inducing fear or humor, on emotions, perceived effectiveness, support for tobacco control policies, urges to smoke, and susceptibility to smoke. Participants (N = 108; 54 smokers) of both genders were randomly assigned to one of the two following emotion ads condition: fear (N = 52) or humor (N = 56). During exposure, the continuous flow of their emotions by self-report and physiologically was collected. Measures of ads impact on emotions, perceived effectiveness, urges and susceptibility to smoking, and support for tobacco policies were applied after exposure. The results have shown that fear ads were perceived as more effective and reduced the urges to smoke in smokers. Non-smokers were more supportive of tobacco control policies. In conclusion, this study showed that fear campaigns can reduce the urge to smoke among smokers and are perceived to be more effective. This perceived effectiveness can be partially explained by feelings of fear, regardless the other emotions it also triggers, and of the smoking status.

Resumo Várias campanhas antitabágicas são usadas para reduzir o consumo de tabaco. No entanto, até ao momento não existe um consenso sobre a eficácia da indução de emoções específicas nestas campanhas. Este estudo testou os efeitos de dois tipos de campanhas antitabágicas, induzindo Medo ou Humor, nas emoções, na perceção de eficácia das campanhas, no apoio a políticas antitabágicas, no desejo de fumar, e na suscetibilidade para fumar. Os participantes (N = 108; 54 fumadores), de ambos os sexos, foram aleatoriamente distribuídos para uma das seguintes campanhas indutoras de emoções: medo (N = 52) ou humor (N = 56). Durante a exposição, registou-se o fluxo contínuo das emoções autorreportadas e as respostas fisiológicas. Após a exposição avaliou-se o impacto das campanhas nas emoções, na perceção de eficácia, nas políticas antitabágicas, no desejo e na suscetibilidade para fumar. Os resultados evidenciaram que as campanhas indutoras de medo foram percecionadas como mais eficazes e reduziram o desejo de fumar em fumadores. Políticas antitabágicas foram mais apoiadas por não fumadores. Futuramente deverá considerar-se que induzir diferentes emoções em campanhas antitabágicas pode ter efeitos distintos a nível afetivo e cognitivo, com possível relevância para a mudança comportamental.

Cassava biopolymer polyamide hydrogel accelerates healing of induced skin woundsin rats / Hidrogel de biopolímero de poliamido de mandioca acelera o processo de cicatrização em feridas cutâneas induzidas em ratos

This study aimed to macroscopically and microscopically evaluate the healing of skin wounds induced in rats by topical application of cassava polyamide biopolymer hydrogel. In total, 32 rats were used and divided into four groups (n= 8): negative control - saline solution; positive control - use of commercial ointment; experimental group - I - ointment + cassava hydrogel; experimental group - II - cassava hydrogel. A 1cm2 wound induced on the animals dorsum was treated and evaluated. At day 21 post-operation, the animals were sacrificed by anesthetic overdose, and then 1cm2 of cicatricial skin from the wound region was collected. The material was cut to evaluate healing. In the macroscopic evaluation, complete healing was observed at the end of 21 days. Re-epithelialization was observed histologically; the connective tissue in the negative control, positive, and experimental - I groups was characterized by an abundance of collagen fibers, fibroblasts, and blood vessels. In experimental group - II additional healing was observed, as evidenced by the arrangement of collagen fibers and fibroblasts, and the reduction of neoformed vessels. Thus, we concluded that the hydrogel can assist in healing skin wounds, especially in the remodeling phase.(AU)

O objetivo deste estudo foi avaliar macro e microscopicamente a cicatrização de feridas cutâneas induzidas em ratos, a partir da aplicação tópica do hidrogel de biopolímero de poliamido de mandioca. Trinta e dois ratos foram divididos em quatro grupos (n= 8): controle negativo, tratado com solução salina; controle positivo, com pomada comercial; grupo experimental - I, com pomada + hidrogel de mandioca; grupo experimental - II, com hidrogel de mandioca. Feridas induzidas de 1cm 2 no dorso dos animais foram tratadas e avaliadas em intervalos de três a quatro dias. No 21º dia do pós-operatório, os animais foram mortos por aprofundamento anestésico, em seguida foi coletado 1cm 2 de pele da região cicatricial. O material foi cortado, corado pelas técnicas de hematoxilina-eosina e azocarmine-G, para avaliação da cicatrização. Na avaliação macroscópica, foi observada cicatrização completa no final do período de 21 dias. Histologicamente, observou-se reepitelização, o tecido conjuntivo no grupos controle negativo, positivo e experimental - I se caracterizou pela abundância de fibras colágenas, fibroblastos e vasos sanguíneos. No grupo experimental - II, a cicatrização sugere avanço de etapas, evidenciado pelo arranjo das fibras colágenas, pela redução de fibroblastos e dos vasos neoformados. Assim, foi possível concluir que o hidrogel de biopolímero de amido de mandioca pode auxiliar na cicatrização de feridas cutâneas, principalmente na fase de remodelação.(AU)

Does the retention system influence the stability of implant-supported maxillary overdentures? A comparison with fixed and conventional dentures.

PURPOSE: The purpose of this in vitro study was to compare the stability of removable implant-supported maxillary overdentures with fixed complete dentures and conventional dentures. METHODS: Four types of complete dentures were tested: conventional complete dentures; overdentures retained by a male resilient attachment system; overdentures retained by a combination of clip bar and attachment system; and fixed complete dentures. Each group was placed in the posterior and anterior region and the stability was recorded by measuring the vertical displacement of the prosthesis. RESULTS: There was a difference in the vertical movement of the prosthesis according to the type of system. The results showed that the behavior of the overdenture retained by a combination of a clip bar and attachment system is comparable with the stabilization of an implant-retained fixed complete denture. CONCLUSIONS: Overdentures retained by a combination of a clip bar and attachment presented better stability and retention capacity under our experimental conditions, close to that of the positive control (fixed complete denture), with the advantages of removable overdentures.

Vesicouterine Fistula (Youssef Syndrome): Case Report and Literature Review.

OBJECTIVE: To describe a case of vesicouterine fistula and to review the literature related to this condition. METHODS: For the review, we accessed the MEDLINE, BIREME and LILACS databases; the references of the searched articles were also reviewed. RESULTS: A 38-year-old woman, in the 1st day after her 3rd cesarean, presented heavy hematuria, which was considered secondary to a difficult dissection of the bladder. A total of 6 months after delivery, she failed to resume her regular menstrual cycles and presented cyclic menouria and amenorrhea. At this time, she had two episodes of urethral obstruction by blood clots. She remained without a correct diagnosis until about two years postdelivery, when a vesicouterine fistula was confirmed through cystoscopy. A surgical correction through open abdominal route, coupled with hysterectomy, was performed. After the surgery, the symptoms disappeared. The review showed a tendency of change in the relative frequency of the different types of genitourinary fistulae. Vesicovaginal fistulae, usually caused by inadequate care during labor, are becoming less frequent than those secondary to medical procedures, such as vesicouterine fistulae. The most common cause of this latter kind of fistula is cesarean section, especially repeated cesarean sections. The diagnosis is confirmed through one or more imaging exams, or through cystoscopy. The most common treatment is surgical, and the routes are: open abdominal, laparoscopic, vaginal or robotic. There are some reports of success with the conservative treatment. CONCLUSION: Vesicouterine fistulae are becoming more common because of the increase in the performance of cesarean sections, and the condition must be considered a possible complication thereof.

OBJETIVO: Apresentar um caso de fístula vesico-uterina e realizar revisão da literatura sobre esta condição. MéTODOS: Revisão realizada consultando-se as bases MEDLINE, BIREME e LILACS, além das referências dos artigos consultados. RESULTADOS: Uma mulher de 38 anos, após sua terceira cesárea, no puerpério imediato, apresentou hematúria importante, que foi atribuída a uma dificuldade na dissecção da bexiga durante o procedimento. Seis meses pós-parto, em vez de retomar os ciclos menstruais regulares, apresentou menúria cíclica e amenorreia (síndrome de Youssef). A paciente chegou a apresentar obstrução uretral por coágulos, e permaneceu sem diagnóstico correto até cerca de anos pós-parto, quando este foi feito por cistoscopia. Ela foi então submetida a correção cirúrgica por via abdominal, associada a uma histerectomia, com desaparecimento dos sintomas. A revisão mostrou que tem havido mudança na frequência dos vários tipos de fístulas urogenitais. As fístulas vesicovaginais, normalmente secundárias à má assistência durante o parto, têm sido mais raras, enquanto aquelas secundárias a procedimentos médicos, como as vesicouterinas, têm sido mais frequentes. A causa mais comum deste tipo de fístula é a cesárea, especialmente a de repetição. A apresentação pode ser de amenorreia e menúria e/ou perda urinária. O diagnóstico é feito por um ou mais métodos de imagem ou cistoscopia. O tratamento mais comum é cirúrgico, por via abdominal aberta, laparoscópica, transvaginal ou robótica. Existem relatos de cura com tratamento conservador. CONCLUSãO: As fístulas vesicouterinas têm sido mais comuns devido ao aumento da proporção de cesáreas. Deve-se ter em mente a possibilidade deste diagnóstico e considerá-las uma das possíveis complicações da cesárea.

Improvement of the stereoselectivity of the glycosylation reaction with 2-azido-2-deoxy-1-thioglucoside donors.

2-Azido-2-deoxy-1-thioglucoside donors with an electron withdrawing group at position 6 were employed to study the stereoselectivity of the glycosylation reaction with several acceptors, ranging from unhindered small primary alcohols to other sugars and steroids, using NIS/TfOH as promoter. p-Tolyl 2-azido-3,4-di-O-benzyl-6-O-chloroacetyl-2-deoxy-1-thio-α/ß-D-glucopyranoside afforded the higher α-selectivity, showing that a stronger electron withdrawing ester at O-6 influenced the anomeric selectivity towards the 1,2-cis glucosides. The anomeric stereoselectivity was highly dependent on the acceptor.

Effects of the combined artesunate and mefloquine antimalarial drugs on rat embryos.

Artemisinins combination therapy (ACT) is the first choice therapy for falciparum malaria. Data on the safety of ACTs in pregnancy are limited and controversial and the use is not recommended on the first trimester. To evaluate the effects of isolated and combined artesunate (AS)/mefloquine (MQ) on embryo rats, pregnant rats were treated orally with AS (15 and 40 mg/kg body weight (bwt)/day), MQ (30 and 80 mg/kg bwt/day) and AS/MQ (15/30 and 40/80 mg/kg bwt/day) on days 9-11 post coitum (pc). The dams were euthanized on day 12 pc and gestational and embryos histological parameters were evaluated. Embryolethality and histopathological anomalies were significant when AS was given alone or combined with MQ. Combination of AS and MQ did not enhance their toxicity compared to their separate administrations; on the other side, there was a reduction in the toxic effects of the AS when combined with MQ. Isolated MQ did not induce developmental toxicity.

Oral administration of different forms of a tolerogenic peptide to define the preparations and doses that delay anti-DNA antibody production and nephritis and prolong survival in SLE-prone mice.

Therapeutic agents currently in use to treat systemic lupus erythematosus (SLE) are predominantly immunosuppressive agents with limited specificities. Multiple groups, including ours, have illustrated that inducing tolerance in SLE animal models ameliorates disease symptoms and increases survival. We examined if oral administration of a tolerogenic peptide could affect SLE disease progression. The pConsensus (pCons) peptide, based on protein sequences of anti-double stranded (anti-ds)DNA antibodies, induces tolerance through upregulation of regulatory T cells when administered intravenously. Six different forms of pCons, including multiple antigenic peptides (MAP) and cyclic peptides made up of L- and D-amino acids, at three different concentrations, were fed to BWF1 SLE-susceptible mice for 30 weeks. Mice fed 100 µg of L-MAP or D-MAP had less cumulative proteinuria and serum anti-dsDNA antibody levels than controls. In addition, animals in these groups also survived significantly longer than controls with a corresponding increase in serum transforming growth factor beta (TGFß, implying a protective role for pCons-induced regulatory T cells. Oral administration of a tolerogenic peptide is a safe, effective method for ameliorating SLE disease manifestations and prolonging survival in SLE-prone mice. Induction of oral tolerance using modified pCons peptides could lead to a novel targeted therapy for human SLE.

Colony size, sex ratio and cohabitation in roosts of Phyllostomus hastatus (Pallas) (Chiroptera: Phyllostomidae).

Phyllostomus hastatus bat is species broadly distributed over the Neotropical region, which uses as diurnal roosts caves, hollow trees, palm leaves and human buildings. Thirteen diurnal roosts of P. hastatus were analysed from 1990 to 2009 in several localities of Rio de Janeiro State, regarding environment (rural, urban or protected area), type of roost (hollow tree, basement or roof), sex ratio and cohabitation. A nocturnal roost was also analysed. Sex ratio of P. hastatus varied considerably among roosts what may be explained by the fact this species can roost alone, in couples, in harems or in groups of bachelor males. Phyllostomus hastatus was observed in cohabitation with three other species: Molossus rufus, Molossus molossus and Myotis nigricans. Due to the frequency of cohabitation observed between P. hastatus and species of the genus Molossus, one or more advantages for the members of this association may be expected. The simultaneous usage of a feeding roost by a group of bachelor males is unknown information in the literature, and may suggest that this kind of group may interact with each other even when away from their diurnal roosts.

A influência do acompanhamento farmacoterapêutico na adesão à terapia anti-hipertensiva e no grau de satisfação do paciente / Influence of pharmacotherapeutic follow-up on patient compliance and satisfaction with antihypertensive therapy

O objetivo desta pesquisa foi proporcionar o serviço de Acompanhamento Farmacoterapêutico (AFT) a pacientes hipertensos usuários da Farmácia Popular de Alfenas (MG), além de avaliar a adesão do usuário aos medicamentos antes e após o AFT e o grau de satisfação com o serviço prestado. O trabalho foi realizado com 27 pacientes de ambos os sexos e com faixa etária entre 40 e 70 anos ou mais. Os pacientes foram divididos em grupo controle e teste, ambos responderam ao questionário de adesão no início do estudo e, ao final, apenas os pacientes do grupo teste o fizeram. Os pacientes do grupo teste receberam Acompanhamento Farmacoterapêutico durante dez meses (2008) e, ao final desse período, responderam o questionário de satisfação pelo serviço. Um dos motivos mais importantes para a não adesão foi o esquecimento de administrar o medicamento (67% para ambos os grupos). Outros fatores, como a falta de informação sobre a doença e a não compreensão sobre como utilizar os medicamentos, foram sanados com a intervenção farmacêutica. Dos pacientes participantes desta pesquisa, 80% achavam importante o trabalho conjunto do farmacêutico com o médico e 100% disseram que continuariam a utilizar o serviço prestado e o indicariam a amigos e parentes. Os dados sugerem que as intervenções farmacêuticas foram efetivas no sentido de aumentar a adesão no grupo que recebeu AFt e que os pacientes ficaram satisfeitos com o serviço prestado.

This research was designed to provide a Pharmacotherapeutic Follow-up (PF) service to hypertensive patients who attend the Popular Pharmacy in Alfenas (Minas Gerais, Brazil) and to assess user adherence to medication before and after the PF and the degree of satisfaction with the service rendered. This study was carried out with 27 patients of both sexes, aged 40 years and above. The patients were divided into two groups, control and test; all patients answered the adherence questionnaire at the beginning of the study and, at the end, only those in the test group. The patients in the test group received PF for ten months (2008) and, at the end of this period, they were asked to complete a questionnaire regarding their satisfaction with the service. One of the commonest reasons given for non-adherence to medication was forgetfulness (67% for both groups). Other problems, such as lack of information on the disease and poor understanding of how to take the medicines, were solved by pharmaceutical intervention. According to 80% of the patients involved, this teamwork between pharmacist and physician is important, and 100% reported they would continue to use the service and would recommend it to friends and relatives. The data suggest that pharmaceutical interventions were effective in improving adherence to medication among patients in the group that received PF and that the patients were satisfied with the service given.

Bat diversity of Ilha da Marambaia, Southern Rio de Janeiro State, Brazil (Chiroptera, Mammalia).

Few sites have been well sampled for bats, and samplings in islands are even scarcer. Therefore, the objectives of the present study were: (1) to list the bat species of Ilha da Marambaia; (2) to compare richness, abundance and biomass of bat guilds found there; (3) to analyse abundance patterns of bat species; and (4) to compare richness, abundance and composition of the bat fauna among different kinds of environment. To capture bats we used mist nets set in five different environments, totalising 3559.2 net-hours, during 37 nights between October 2006 and August 2008. A total of 1,133 captures were accomplished, comprising 34 species from five families. The most abundant species was Molossus molossus. Frugivorous bats exhibited higher richness, abundance and biomass if compared to other guilds. Most species (N = 22) exhibited abundances between 1 to 10% of all captures. Sixteen species were restricted to just one of the environments sampled. The high richness may be attributed to sampling carried out in several environments, and to the capture of insectivorous species over water bodies.

A total of 1,133 captures were accomplished, comprising 34 species from five families. The most abundant species was Molossus molossus. Frugivorous bats exhibited higher richness, abundance and biomass if compared to other guilds. Most species (N = 22) exhibited abundances between 1 to 10 percent of all captures. Sixteen species were restricted to just one of the environments sampled. The high richness may be attributed to sampling carried out in several environments, and to the capture of insectivorous species over water bodies.

Poucos são os locais satisfatoriamente amostrados para morcegos e menos ainda as ilhas. Os objetivos deste estudo foram listar as espécies de morcegos da Ilha da Marambaia, comparar a riqueza, abundância e biomassa das guildas de morcegos encontradas, analisar o padrão de abundância das espécies de morcegos e comparar a riqueza, abundância e composição entre os diferentes ambientes amostrados. O método de amostragem consistiu do uso de redes de neblina armadas em cinco ambientes diferentes, totalizando 3559,2 redes-hora, em 37 noites entre outubro de 2006 e agosto de 2008. Foram obtidas 1.133 capturas, compreendendo 34 espécies de cinco famílias. A espécie mais abundante foi Molossus molossus. Os frugívoros apresentaram maior riqueza, abundância e biomassa. A maior parte das espécies (N = 22) apresentou abundâncias entre 1 e 10 por cento do total de capturas. Dezesseis espécies foram restritas a apenas um dos ambientes amostrados. A elevada riqueza encontrada pode ser atribuída à realização de coletas em vários ambientes, e a captura de espécies insetívoras sobre a água.
