Résumé :

General insights into the causes and effects of social structure can be gained from comparative analyses across socially and ecologically diverse taxa, such as bats, but long-term data are lacking for most species. In the neotropical fringe-lipped bat, Trachops cirrhosus , social transmission of foraging behaviour is clearly demonstrated in captivity, yet its social structure in the wild remains unclear. Here, we used microsatellite-based estimates of relatedness and records of 157 individually marked adults from 106 roost captures over 6 years, to infer whether male and female T. cirrhosus have preferred co-roosting associations and whether such associations were influenced by relatedness. Using a null model that controlled for year and roosting location, we found that both male and female T. cirrhosus have preferred roosting partners, but that only females demonstrate kin-biased association. Most roosting groups (67%) contained multiple females with one or two reproductive males. Relatedness patterns and recapture records corroborate genetic evidence for female philopatry and male dispersal. Our study adds to growing evidence that many bats demonstrate preferred roosting associations, which has the potential to influence social information transfer.

Résumé :

Investigaciones sobre toxicidad ambiental por pesticidas se han realizado principalmente en mamíferos terrestres, pero existe poca información sobre plaguicidas organoclorados en murciélagos. Teniendo en cuenta el papel funcional de este grupo en varios procesos ecosistémicos como insectívoros, frugívoros y polinizadores, su afectación puede estar causando un impacto negativo en la salud de los ecosistemas naturales. En Colombia, no hay estudios que documenten esta problemática; por tanto, el objetivo fue determinar la presencia de plaguicidas organoclorados en el ensamblaje de murciélagos del bosque húmedo tropical (bh-T) en Córdoba, Colombia. Se evaluó la presencia de organoclorados en hígado y músculo de murciélagos del sector Manso-Tigre, un área protegida con ocupación campesina. La concentración de plaguicidas organoclorados como Aldrin, Dieldrin, Endrin, Heptacloro epóxido, α-BCH, βBCH, γ-BCH, 2,4-DDD, 2,4-DDT, 4,4-DDE y 4,4-DDT, se determinó por cromatografía de gases. Niveles de organoclorados en hígado y músculo presentaron diferencias significativas (P<0,05). Se detectó mayor contenido de organoclorados en hígado en las especies Trachops cirrhosus (α–BCH, γ-BCH, Endrin, pp-DDE), Desmodus rotundus (β-BCH), Micronycteris microtis (Aldrin), Platyrrhinus helleri (Heptacloro) y Phyllostomus hastatus (pp-DDT). En tejido muscular, la concentración de organoclorados fue mayor en Trachops cirrhosus (α-BCH, γ-BCH, Endrin, pp-DDE), Artibeus planirostris (β-BCH), Micronycteris microtis (Aldrin, Heptacloro) y Phyllostomus hastatus (pp-DDT). La contaminación por organoclorados en murciélagos posiblemente está relacionada con el uso de agroquímicos, insecticidas y compuestos fosfatados para uso agrícola. Los resultados permiten reconocer a los murciélagos como bioindicadores de contaminación ambiental al indicar procesos de cambios o disturbios en los hábitats.

Résumé :

The aim of this paper is to evaluate the taxonomic diversity of fossil and extant bats from the region of the Serra da Mesa in the State of Goias, Central Brazil. Quaternary fossils were obtained from four limestone caves, namely Igrejinha, Carneiro, Nossa Senhora Aparecida, and Itambé. Information on extant bat fauna used for comparison were obtained from literature and from the collection of Museu Nacional (Rio de Janeiro). The taxonomic identification of the fragments was based on a comparative study of the masticatory apparatus of extant and fossil bat species. A total of 430 fragments were identified, comprising 27 species: Anoura geoffroyi, Artibeus sp., Carollia sp., Chrotopterus auritus, Desmodus rotundus, Desmodus sp., Emballonuridae sp. indet., Eptesicus/ Histiotus, Glossophaga sp., Lionycteris spurrelli, Lonchorhina aurita, Micronycteris megalotis, Mimon bennetti, Mimon crenulatum, Molossidae sp. indet., Myotis sp., Natalus stramineus, Phylloderma sp. n., Phyllostomus discolor, Phyllostomus hastatus, Platyrrhinus sp., Pteronotus davyi, Pteronotus parnelli, Sturnira sp., Tonatia sp. n., Lophostoma silvicola, and Trachops cirrhosus. Phyllostomidae was the most speciose family, but surprisingly most of the fossil fragments were attributed to the families Natalidae and Mormoopidae. Both of which are rare in the area today. The population reduction of these hot-humid-cave dwelling species (Natalus and Pteronotus) may suggest the climate of the area was warmer and wetter during some interval of the Late Pleistocene or Early Holocene. This study presents the first record of the genera Lionycteris, Lonchorhina and Trachops from the Quaternary of South America. The diversity of Chiroptera found in Serra da Mesa is equivalent to that described for Bahia, which heretofore has the most abundant record for Quaternary bats from South America.

Résumé :

Abstract Chemical signals can play important roles in communication, and this is especially true for social mammals such as bats. Male fringe-lipped bats (Trachops cirrhosus) produce an odorous substance on their forearm, called forearm crust. Only adult males with descended testes produce forearm crust. This is thus a sexually dimorphic odour, which suggests that it is a sexually selected trait. Since males lack a specific gland on their forearm we sought to identify the source of the forearm crust. Our second aim was to test female and male preference for this trait. Based on gas chromatography and mass spectrometry analyses we tentatively identified several compounds that were exclusive to the forearm crust. We found that the chemical composition of the forearm crust was not mainly composed of chest gland secretions or urine. We conducted a y-maze odour preference experiment to test whether adult females and reproductive males preferred the odour of a male with forearm crust compared to the odour of a male without forearm crust. Contrary to our prediction we found that females did not approach the scent of a male with forearm crust more frequently than the scent of male without forearm crust. We found that males with forearm crust, however, preferred the odour of males without forearm crust. Overall our results suggest that in this Neotropical bat species, reproductive males could use odorous signals in the forearm crust to mediate interactions between reproductive males and potentially avoid costly competition for mates or aggression. In sum, our results shed light on the role that chemical mediated signals can play in mammalian social behaviour.

Pesquisas recentes têm mostrado que a abordagem molecular é uma poderosa ferramenta no reconhecimento de clados que podem ter escapado do reconhecimento pela taxonomia tradicional devido a sua convergência morfológica. Apesar de ser amplamente distribuído geograficamente e por ambientes distintos, Trachops é considerado um gênero monotípico. Questionamentos sobre o número de táxons que o gênero poderia abranger foram levantados anteriormente, entretanto os estudos permaneceram inconclusivos, continuando a hipótese de especiação críptica no gênero. Diante deste cenário, este trabalho teve como objetivo analisar a diversidade genética de Trachops, utilizando sequências de DNA mitocondriais e um nuclear de indivíduos da Mata Atlântica, do Cerrado, da Amazônia, da América Central e do México. Apesar do marcador nuclear não revelar polimorfismos suficientes para esclarecer a história da espécie, análises filogenéticas e populacionais, gerados pela análise do citocromo c oxidase I (COI) e citocromo b mostraram alta diversidade dentro do gênero, com forte estruturação geográfica. Os nove clados encontrados pelas análises do COI divergiram entre o Plioceno e o Pleistoceno e é possível que os clados que estão em zonas de simpatria tenham divergido em alopatria e restabelecido contato posteriormente. O Escudo das Guianas pode ter exercido influência na diversificação dos grupos amazônicos, bem como a Hipótese do Lago. Todavia, essas são especulações de prováveis fatores que possam ter contribuído para a diversidade do gênero. Aplicando-se o conceito filogenético de espécies, os clados encontrados poderiam ser diagnosticados como nove espécies válidas. A combinação com outros caracteres, como outro marcador nuclear e a morfologia, deve ser utilizada como complemento aos dados do DNA mitocondrial.

Neste trabalho foram estudadas cromossomicamente as espécies de morcegos Phyllostomidae Lonchorhina aurita (Lonchorhininae) e Trachops cirrhosus (Phyllostominae). Diferentes técnicas citogenéticas foram usadas, incluindo análise convencional, bandeamentos G, C, coloração com nitrato de prata e fluorocromos base específicos. Dados da análise convencional obtidos para L. aurita e T. cirrhosus revelaram constituição cariotípica de 2n=32,XY (NF=60) e 2n=30,XY (NF=56), respectivamente. Estes resultados estão de acordo com aqueles descritos na literatura, exceto pela morfologia dos cromossomos sexuais, indicando variação cromossômica geográfica para essas espécies. Adicionalmente, sugere-se que a morfologia acrocêntrica do cromossomo X de T. cirrhosus constitui um caráter autapomórfico e possivelmente foi originada a partir de uma inversão pericêntrica. O bandeamento C revelou padrão pericentromérico de distribuição da HC em todos os autossomos e no X. O cromossomo Y foi quase totalmente heterocromático nas duas espécies. A coloração com AgNO3 revelou RONs localizadas no braço curto do par 13 em L. aurita e no braço longo do par 11 em T. cirrhosus. Nas duas espécies a coloração CMA3/DA/DAPI revelou padrões de bandas R evidenciados pelo CMA3, enquanto que o fluorocromo DAPI mostrou uma coloração uniforme em todos os cromossomos. As regiões heterocromáticas pericentroméricas de alguns cromossomos apresentaram uma marcação CMA3 +. A coloração seqüencial AgNO3/CMA3/DAPI revelou que as RONs são CMA3 positivas em L. aurita e CMA3 neutras em T. cirrhosus, indicando uma heterogeneidade quanto à composição de bases da HC nas RONs

Résumé :

Cette thèse explore la systématique moléculaire et morphologique des chauves-souris Phyllostomidées, utilisant des génomes mitochondriaux complets pour éclairer les relations évolutives, le statut taxonomique et la spéciation cryptique au sein de cette famille diverse. Dans le premier chapitre, je présente une phylogénie révisée des Phyllostomidae basée sur des génomes mitochondriaux complets de 26 espèces, dont 23 ont été nouvellement séquencées pour cette étude. Grâce à une analyse minutieuse, j'ai établi un cadre évolutif robuste qui clarifie les relations auparavant incertaines parmi les sous-familles, notamment celles des Lonchorhininae et des Macrotinae. Ce travail pose les bases pour une classification plus précise au sein de la famille. Le deuxième chapitre se concentre sur le genre Trachops, réévaluant son statut taxonomique à travers une approche intégrée combinant des données morphologiques, morphométriques et moléculaires. Nos découvertes suggèrent l'élévation de T. cirrhosus ehrhardti au rang d'espèce, reconnaissant sa distinction génétique et morphologique dans le sud-est du Brésil. En plus, je ne trouve aucun soutien pour maintenir T. c. coffini comme une sous-espèce distincte. Le genre Trachops comprendrait alors deux espèces monotypiques, T. cirrohosus et T. ehrhardti. Le troisième chapitre enquête sur la biodiversité et la spéciation cryptique potentielle au sein des genres Phylloderma et Macrophyllum, avec un accent particulier sur la révélation d'une nouvelle espèce cryptique d'Amérique centrale. Les analyses complètes indiquent la présence de deux clades fortement soutenus au sein de Phylloderma stenops et Macrophyllum macrophyllum, menant à la proposition d'élever la population d'Amérique centrale du Nord de Phylloderma, P. s. septentrionalis, au rang d'espèce, et l'introduction de Macrophyllum sp. nov., une nouvelle espèce endémique de la région. Cette thèse souligne la complexité de la diversité des chauves-souris Phyllostomidées et le rôle crucial des analyses moléculaires et morphologiques intégrées pour découvrir la diversité cachée. Cette contribution fournit une compréhension plus claire des processus de spéciation chez les chauves-souris tropicales, soulignant l'importance d'une classification taxonomique précise pour des stratégies de conservation efficaces
This thesis explores the molecular and morphological systematics of Phyllostomid bats, utilizing complete mitochondrial genomes to illuminate the evolutionary relationships, taxonomic status, and cryptic speciation within this diverse family. In the first chapter, I present a revised phylogeny of Phyllostomidae based on complete mitochondrial genomes from 26 species, 23 of which are newly sequenced for this study. Through meticulous analysis, I achieved a robust evolutionary framework that clarifies previously uncertain relationships among subfamilies, notably those of Lonchorhininae and Macrotinae. This work sets the stage for a more accurate classification within the family. The second chapter focuses on the genus Trachops, reassessing its taxonomic status through an integrated approach that combines morphological, morphometric, and molecular data. Our findings suggest the elevation of T. cirrhosus ehrhardti to species status, recognizing its genetic and morphological distinctiveness in southeastern Brazil. Additionally, I find no support for maintaining T. c. coffini as a distinct subspecies. The genus Trachops would then consist of two monotypic species, T. cirrohosus, and T. ehrhardti. Chapter three investigates the biodiversity and potential cryptic speciation within the genera Phylloderma and Macrophyllum, with a particular emphasis on revealing a new cryptic species from Central America. Our comprehensive analyses indicate the presence of two highly supported clades within both Phylloderma stenops and Macrophyllum macrophyllum, leading to the proposal of elevating the North Central American population of Phylloderma, P. s. septentrionalis, to species status, and the introduction of Macrophyllum sp. nov., a new species endemic to the region. This thesis underscores the complexity of Phyllostomid bat diversity and the critical role of integrated molecular and morphological analyses in uncovering hidden diversity. This contribution provides a clearer understanding of speciation processes in tropical bats, emphasizing the importance of accurate taxonomic classification for effective conservation strategies

Résumé :

Trachoma continues to be the leading cause of infectious blindness. Mass administration of antibiotics is part of the current control effort, an approach which is costly when drugs are not donated. Trachoma has been shown to cluster by household and therefore this unit could be a means to target treatment. This thesis shows that active inflammatory disease is a more sensitive marker of infection within an individual’s household than just in that individual. The potential impact of a more efficient, targeted treatment of households with at least one member with active disease depends on the relative contributions of community and household transmission of infection. A mathematical model of the household transmission of ocular Chlamydia trachomatis was fitted to detailed demographic and prevalence data from four endemic populations, two in The Gambia and two in Tanzania. Maximum likelihood estimates of the household and community transmission coefficients were obtained. The estimated household transmission coefficient exceeded both the community transmission coefficient and the rate of clearance of infection by individuals in three of the study populations, indicating persistent transmission of infection within households. Allowing children and adults to have a different duration of infection improved the fit of the model to the data in three populations. For a given level of treatment coverage, targeting antibiotics to households with active disease was predicted to have similar post‐treatment dynamics to those observed after mass treatment but to be much more drug sparing. Using available cost data this approach was shown to be more cost effective when antibiotics are not donated. If targeting increases treatment coverage of diseased households, it was found to be more effective and more cost‐effective than mass treatment even if antibiotics are donated. Further work is now required to explore the feasibility of incorporating household targeted treatment into trachoma control programmes.

Résumé :

Introdução: as regiões tropicais têm enfrentado constante fragmentação e isolamento dos ambientes florestais, comprometendo a biodiversidade e expondo diversas espécies ao risco de extinção. Objetivos: avaliou-se, portanto, a importância da Ordem Chiroptera como mantenedores e reguladores dos ecossistemas neotropicais e sua possível contribuição para estudos ambientais. Material e métodos: foi realizada revisão bibliográfica exploratória sobre a temática abordada, com foco nas espécies de quirópteros presentes nos biomas brasileiros e seus hábitos alimentares. Resultados: observou-se que no Brasil, há, aproximadamente, 168 espécies de morcegos catalogadas, pertencentes a nove famílias, representando 1/3 da mastofauna brasileira. Sua diversidade de hábitos alimentares, associada às suas adaptações morfológicas, permitem a utilização dos mais variados habitats, em complexa relação de interdependência com o meio. À medida que partilham recursos, os quirópteros influenciam a dinâmica dos ecossistemas naturais agindo como dispersores de sementes (espécies frugívoras), polinizadores (espécies nectarívoras) e reguladores de populações animais (espécies animalívoras, piscívoras, carnívoras e insetívoras), além de garantirem o aporte de nutrientes em ambientes cavernícolas por meio da excreção de suas fezes (guano). Devido à sensibilidade dos morcegos às alterações ambientais, à essa variedade de espécies e ao seu amplo espectro de locomoção, diversos autores os descrevem como importantes indicadores de fragmentação dos habitats e da qualidade ambiental. Os morcegos da subfamília Phyllostominae, como Chrotopterus auritus e Trachops cirhossus, são potenciais indicadores de áreas menos degradadas, sendo que áreas com maior abundância desta subfamília são consideradas mais preservadas, assim como a presença de morcegos do gênero Sturnira pode indicar alteração do ambiente. Já as espécies frugívoras tem sido consideradas as principais responsáveis pela ampliação de áreas florestadas e pela regeneração de ambientes florestais mediante a dispersão das sementes nas fezes. Evidenciou-se, também, que devido aos quirópteros cavernícolas, outras espécies podem coexistir em ambientes subterrâneos, uma vez que se alimentam do guano e de restos alimentares deixados ao chão pelos morcegos. Conclusão: a importância funcional da quiropterofauna para a dinâmica dos ecossistemas tropicais poder ser sugerida pela diversidade e densidade das espécies de morcegos, demonstrada pelo seu potencial na recuperação de ecossistemas florestais e atuação como bioindicadores de perturbações ambientais na região Neotropical.

Résumé :

Congenital Tracheal Stenosis (CTS) is a rare birth defect requiring surgical interventions when it affects more than 30% of the trachea. Slide tracheoplasty, the current standard of care, is associated with reinterventions including the need for intraluminal stenting leading to increased airway infections. We propose a novel Bio-Synthetic Graft for long segment tracheal reconstructions in CTS patients. Preliminary bench performance testing, using lamb tracheas, shows that the Bio-Synthetic Graft reconstructed tracheas have comparable radial, axial and bending stiffness in hyperextension to healthy tracheas and resist collapse when subjected to bending in flexion. These results suggest that Bio-Synthetic Graft could be a promising alternative to existing solutions for long segment CTS.

Résumé :

Abstract Since human organs, such as blood vessels, tracheas and urethras, have similar characteristics to collapsible tubes, a lot of studies on both steady and unsteady flow through the collapsible tubes have been done in biological and physiological fields [1, 2]. Recently, Sakurai et al carried out an experimental analysis concerning the effect of longitudinal tension on collapsible tube flow [3]. However, the real figure of this complex system, including the influence of the tube parameters on self-excited oscillation is still not sufficiently understood. In present report an experiment was performed to investigate the dynamic characteristics of a collapsible tube flow. The effect of initial axial strain of the tube on the self-excited oscillation was studied by changing the initial stretch of a thin-walled silicone rubber tube for various values of supply flow rate.
