Full textAbstract:
The morphology of the internal male genitalia of selected genera of Melanoplinae (Orthoptera: Acrididae) was studied. A detailed comparison of these structures was carried out, in an attempt to identify new characters that may be useful in analyzing relationships between the members of the subfamily. Twenty-two genera were examined, mostly of North American distribution, using one exemplar species for each of them. Standard dissection and drawing techniques were followed. The epiphallus and the apical parts of the aedeagus were found to be the most important taxonomic characters. The genera Aptenopedes and Buckellacris were highly divergent from the rest of the melanoplines, while the close relationship between Appalachia, Dendrotettix and Podisma was confirmed by genital characters. Internal male genitalic characters did not provide significant support for many currently recognized tribes and subtribes, suggesting that there is a great need for reclassification in the subfamily.

Full textAbstract:
Merkel cell polyomavirus (MCPyV) is an oncogenic virus exist in about 80% of Merkel Cell Carcinoma (MCC), an aggressive human skin cancer. Evidence of MCPyV existing in other kind of skin neoplasms such as cutaneous squamous cell carcinomas (SCCs) has been reported. Since the major type of cervical cancer is SCCs, MCPyV may be associated with cervical cancer tumorigenesis. A Japanese research group has documented the presence of MCPyV DNA in both cervical SCCs and cervical adenocarcinomas (ACs) from Japanese patients. Nevertheless, the association between MCPyV and cervical cancer remains inconclusive and the prevalence of MCPyV in cervical cancer may show demographic variation. This study is aimed to examine whether MCPyV is present in some of the most common gynaecological cancers, namely cervical cancer, ovarian cancer, endometrial cancer, and gestational choriocarcinoma, in Hong Kong patients.
Genomic DNA was obtained from 50 cases of cervical cancer, 20 cases of ovarian cancer, and 35 common gynaecological cancers cell lines. Genomic DNA extracted from four MCC samples were used as positive controls. The integrity of the samples was first checked by β-globin PCR. Detection of MCPyV was then performed by MCPyV Large T antigen (LT-ag) PCR. Our PCR analysis showed that only 1 out of 50 (2%) of the cervical cancer samples was positive for MCPyV DNA. The PCR product was purified and cloned for sequencing analysis. Comparing the LT-ag sequence obtained from the only MCPyV positive cervical cancer with reference sequence and with the MCPyV sequence from one of the control cases revealed the presence of different MCPyV variants in Hong Kong patients. None of the ovarian cancer, endometrial cancer, or choriocarcinoma was positive for MCPyV. Our data did not support the notion that MCPyV is associated with gynaecological malignancies. MCPyV may hence be a fairly specific oncogenic agent for Merkel cell carcinoma.<br>published_or_final_version<br>Pathology<br>Master<br>Master of Medical Sciences

Sour cherry (Prunus cerasus L. (sin. Cerasus vulgaris Mill., Prunus vulgaris Schur)) is widely grown stonefruit tree in Lithuania.
Productivity of sour cherry orchard depends on many tightly related factors. It's know that negative temperature and spring frosts are important factors determinating plant productivity. These factors must be considered in plant breeding.
Risks of extreme temperatures, humidity deficiency and spring frosts increases due to climate change. Plant reaction to climate change depends on plant species, cultivar and on biotic or abiotic factors. Spring starts earlier and suddenly during past years, thus vegetation of cherries starts earlier. However, probability of plant damage to spring frosts increases due to earlier vegetation, because plants are susceptible to negative temperatures due to loss of the predictive and consequential (secondary) dormancy. The aim of the research was to evaluate DNA polymorphism of sour cherry cultivars with different resistance to spring frosts, to characterize nature of phenological phase changes, to evaluate biochemical characteristics of sour cherry resistance to spring frosts formation by analysis of changes in carbohydrate amount and composition in generative organs and fruit ovaries at different phenological phases, and to evaluate changes in gene expression levels of galactinol synthase and raffinose synthase during flower development. It was established, that specific rhythm of phenological development is... [to full text]<br>Paprastoji vyšnia (Prunus cerasus L. (sin.

Oro temperatūra yra vienas svarbiausių vyšnių paplitimą ir jų derlių lemiantis veiksnys. Žinoma, kad neigiamos temperatūros ir pavasario šalnos yra svarbus veiksnys, į kurį reikia atsižvelgti vykdant augalų selekciją. Keičiantis klimatui, didėja ekstremalių temperatūrų ir drėgmės deficito pavojus bei pavasario šalnų rizika (Augspurger, 2013). Augalų reakcija į klimato kaitos pokyčius priklauso nuo augalo rūšies ir veislės bei abiotinių ir biotinių veiksnių. Pastaraisiais metais pavasaris ateina greičiau ir staigiai. Tai paveikia vyšnias – jų vegetacija prasideda anksčiau. Anksti pradėjus vegetuoti išauga tikimybė, kad augalus pažeis pavasario šalnos. Lietuvoje nuostolių padaro vėlyvos pavasario šalnos, kurių metu pažeidžiami žiedai ir vaisių užuomazgos.

Full textAbstract:
Intermedin (IMD) is a peptide hormone discovered in 2004 belonging to the calcitonin/calcitonin gene-related peptide superfamily. It signals through a Gprotein coupled receptor by the coupling of a calcitonin receptor-like receptor (CRLR) and one of the receptor activity-modifying proteins (RAMPs) 1-3. Due to its similarity to adrenomedullin in structure and functions, IMD is also known as adrenomedullin 2 (ADM2).
Among members of the superfamily, IMD shares the highest degree of homology with ADM, which is a multifunctional vasodilator ubiquitously expressed in various tissues and organs and has been studied by our group for its reproductive functions. It is hypothesized that IMD may be present in the reproductive systems of the rat and exert some effects on reproductive functions.
The objectives of this study were to investigate the expression of IMD and its receptor components in the male and female reproductive systems of the rat, the changes in expression across the oestrous cycle, and its effect on uterine contraction. The gene expression levels of Imd and its receptor components and peptide levels of IMD were measured by RT-PCR and enzyme immunoassay respectively. The effect of IMD on the uterine contraction was studied by the organ bath technique.
Imd mRNA and IMD levels were detected in the testis, epididymis, ventral prostate, coagulating gland, and seminal vesicle of the male rat and the ovary, oviduct, and uterus of the female rat, suggesting possible roles for IMD in both the male and female reproductive systems. In the male, the Imd mRNA levels were the highest in the seminal vesicle but lowest in the testis and the epididymis and IMD peptide levels were the highest in the coagulating gland but lowest in the epididymis. In the female, the Imd mRNA and IMD peptide levels were the highest in the oviduct and the uterus respectively while both the Imd and IMD levels were the lowest in the ovary.
Imd mRNA and IMD levels displayed cyclic changes in various female reproductive tissues across the oestrous cycle. In the ovary, positive immunostaining was detected in the follicles and corpora lutea with more staining in the latter. The Imd mRNA level was significantly higher at prooestrus than dioestrus while the IMD peptide level was significantly higher at metoestrus than dioestrus. In the oviduct, the Imd mRNA level was the lowest at dioestrus but the IMD peptide level was the highest at dioestrus. Positive immunostaining was observed in the ciliated epithelial cells. Uterine Imd mRNA level was the highest at prooestrus while the IMD level was the highest at dioestrus. IMD was found in the luminal and glandular epithelia.
IMD significantly reduced the uterine contraction amplitude and frequency but not the basal tone. CGRP receptor antagonist hCGRP8-37 and ADM receptor antagonist hADM22-52 partially abolished the inhibitory effect of IMD on uterine contraction while the IMD specific receptor antagonist hIMD17-47 completely blocked the actions. Enzyme inhibitors of NO (L-NAME) and PI3K (Wortmannin) pathways diminished the IMD-mediated effects on uterine contraction while cAMP/PKA blocker KT5720 had no effect.<br>published_or_final_version<br>Physiology<br>Master<br>Master of Philosophy

A mouse testis cDNA library was screened with an oligonucleotide probe corresponding to a sequence in the 5$ sp prime$ region of mouse N-cadherin cDNA. A composite clone containing three individual cDNAs was isolated. These included a 711 bp cDNA encoding part of mouse testicular N-cadherin, an unidentified 392 bp cDNA, and a 1500 bp cDNA encoding the mouse homologue of a human breast tumor autoantigen.<br>The cadherins, the influenza strain A hemagglutinins, and the fibroblast growth factor receptors are three different families of integral membrane glycoproteins that harbour the amino acid motif histidine-alanine-valine (HAV) in regions involved in protein-protein interactions. In order to identify other proteins that possess the HAV motif in functionally important regions, the SwissProt database was searched using a consensus sequence derived from the cadherins, influenza strain A hemagglutinins, and fibroblast growth factor receptors. This search identified the $ alpha$ chains of the HLA class I histocompatibility antigens as a fourth family of integral membrane glycoproteins with an HAV-containing region that is involved in a protein-protein interaction.

Full textAbstract:
Sexual selection arises via competition for access to mates, and is thus intimately tied to the social environment. For example, individual mating success may depend strongly on how many rivals or mating partners are available. Studies of mate choice and sexual selection may vary the number of mates a subject is presented with during mating experiments, yet it is not clear how this influences the strength and shape of sexual selection acting on traits in either sex. In this thesis I investigate the effect of social environment on sexual selection acting in two closely-related species of lygaeid seed bug: Lygaeus equestris and Lygaeus simulans. Males in both species possess an extremely elongate intromittent organ, which is over two-thirds average male body length. I show that the strength of pre-copulatory selection acting on male processus length in Lygaeus equestris and genital clasper shape in Lygaeus simulans is significantly influenced by the social context. However, selection on male and female body size in Lygaeus equestris is not. Additionally, I use a meta-analysis of 38 published studies to show that mating preferences are significantly stronger when more than one mate option is available, compared to when only a single option is available. I also investigate the functional morphology of male genital traits in Lygaeus simulans, and use formal selection analysis to quantify the strength of selection acting on these traits before, during and after mating. Finally, I use experimental manipulations in Lygaeus simulans to confirm that male processus length directly influences sperm transfer, and that intact genital claspers are required for successful intromission. Overall, my results illustrate that sexual selection in the wild may vary both spatially and temporally depending on the social environment. It is thus especially important that experiments are performed under ecologically relevant conditions.

Full textAbstract:
The management of advanced cervical and ovarian cancers remains a significant challenge as many women fail to respond to recommended therapy, resulting in disease progression and ultimately patient death. Because of tumour heterogeneity, it is rare for all cancers of a particular type to respond to a specific therapy. Many patients therefore receive treatment from which they derive little or no benefit, leading to increased morbidity and costs. A marker that could rapidly predict disease outcome would clearly be beneficial in allowing the administration of tailored therapy while reducing toxicity and cost. Novel functional imaging techniques have the ability to characterise biological tissues and non-invasively integrate physical and metabolic information. These include diffusion weighted MRI (DW-MRI), which is particularly sensitive to the microscopic motion of water molecules and changes in tissue cellularity, as well as dynamic contrast-enhanced MRI (DCE-MRI) which can assess tumour vascular characteristics during the passage of a paramagnetic contrast agent through tissues. Both imaging techniques have demonstrated potential as biomarkers of tumour response in various malignancies such as brain tumours, but have not been fully explored in gynaecological cancers.

Thesis (DMed (Obstetrics and Gynaecology))--University of Stellenbosch, 2010.<br>ENGLISH ABSTRACT: Chapter 1 is a literature review investigating the incidence of cancer in children and
young adults. It describes the most important treatment options including
chemotherapy, radiotherapy and surgery and the effect of treatment on future
endocrine development and fertility. Different primary cancer sites are discussed in
more detail.
Chapter 2 is a literature review on the effects of cancer surgery in women and the
options for fertility sparing. Cervical cancer and pre-cancer are discussed in detail
with options for more conservative surgery in selected patients. A summary of the
available published cases of trachelectomy with pregnancy outcomes is included.
Other gynaecological cancers requiring surgery are also discussed with reference to
conservative options.
Chapter 3 is a literature review about the medical (pharmacological) options for
protection of ovarian function in patients undergoing oncotherapy. The role of
gonadotrophin releasing hormone analogues and hormonal contraceptives in ovarian
suppression is discussed in detail.
Chapter 4 This chapter examines germ cell physiology with reference to cryopreservation. It
includes two major parts. Part 1 is the description of germ cell- and follicle physiology, the principles of cryobiology followed by a review of oocyte
cryopreservation and ovarian tissue preservation. Both slow freezing and vitrification
techniques are described. The second part of chapter 4 is a report on a randomised
controlled evaluation of two different slow freezing cryopreservation protocols. This
experimental study compared ultrastructural changes in fresh and previously
cryopreserved ovarian cortical tissue after equilibration and thawing using two
different cryoprotectants. This is the first randomised investigation into DMSO and
PROH as cryoprotectants.
Chapter 5 is an investigation into cryopreservation of ovarian tissue as a strategy to
protect hormonal function and fertility against gonadotoxic treatment. This chapter
consists of two parts. The first part is a thorough literature review of all the published
work about grafting of previously cryopreserved ovarian tissue. The largest case
series found from a single institution was five patients. Another report of six patients
included patients from various sites in Denmark.
Part 2 is a description of a cohort of patients followed up after re-implantation of
previously cryopreserved ovarian cortical tissue. Follow-up hormone levels of 13
individual cases are described in detail. This is the largest case series ever
reported.
The experimental study described in Chapter 4 and the clinical study described in
Chapter 5 was approved by the ethical research committee of the Faculty of Health
Sciences, Stellenbosch University, project number N05/10/182. Chapter 6 provides an integrated overview of the incidence and treatment of cancer
in young women and how its negative effects may be prevented or mitigated.
Aspects of chemotherapy, radiotherapy and surgery are evaluated where it may
affect future reproductive health. The role of oocyte and ovarian tissue
cryopreservation is discussed. Guidelines are provided for clinicians.<br>AFRIKAANSE OPSOMMING: Hoofstuk 1

Previous issue date: 2012<br>Resumo: Entre as ordens de insetos alados com representantes vivos, os membros da ordem Ephemeroptera estão entre os mais antigos que existem. Suas ninfas são aquáticas e os adultos, alados, sobrevivem por pouco tempo, morrendo logo após o acasalamento. Ainda existem algumas dúvidas sobre a relação dos Ephemeroptera com os demais Pterygota, bem como algumas famílias dentro da ordem são atualmente consideradas parafiléticas. A morfologia do sistema reprodutivo masculino e dos espermatozoides dos insetos pode fornecer informações úteis para estudos filogenéticos. No entanto, tais estudos envolvendo espécies de Ephemeroptera são escassos. O objetivo deste trabalho foi estudar a morfologia do sistema reprodutivo masculino e dos espermatozoides de espécies de Ephemeroptera existentes no Brasil, analisando a variabilidade morfológica encontrada nessas espécies. No Brasil são encontradas espécies pertencentes a dez famílias de Ephemeroptera e analisamos a morfologia do sistema reprodutor masculino de seis espécies pertencentes a cinco famílias e os espermatozoides de 17 espécies pertencentes a nove famílias. Nas seis espécies a morfologia do sistema reprodutivo foi muito constante sem glândulas acessórias ou órgãos especializados no armazenamento de espermatozoides. No entanto, observamos diferentes padrões de organização da musculatura intrínseca dos ductos espermáticos, provavelmente refletindo diferenças na fisiologia reprodutiva de cada espécie. A morfologia dos espermatozoides se mostrou mais variável. As espécies da família Leptophlebiidae possuem espermatozoides aflagelados e imóveis. Nas demais famílias, os espermatozoides são flagelados e móveis. A organização do axonema se mostrou constante nas diferentes espécies com o padrão 9+9+0 típico para esses insetos. Apenas os microtúbulos acessórios mostraram variação na estrutura, podendo assumir o padrão de subunidades 13+7 ou 13+0. Os flagelos são caracterizados por apenas uma mitocôndria que se alonga por quase todo flagelo. A morfologia dos corpos acessórios dos flagelos varia entre as espécies. Parece haver correlação entre a organização das cristas mitocondriais e os corpos acessórios. A morfologia da vesícula acrossomal é variável podendo estar relacionada com diferenças na espessura do corion dos ovos. No início dos flagelos observamos o adjunto do centríolo, que acreditava-se estar ausente nos espermatozoides dos Ephemeroptera. Em uma espécie estudada o núcleo dos espermatozoides está associado paralelamente ao flagelo. Nossos resultados sugerem que os espermatozoides dos Ephemeroptera possuem variabilidade morfológica suficiente para fornecer dados para futuros estudos filogenéticos. No entanto, é preciso que mais espécies sejam estudadas aumentando a abrangência dentro do grupo. Alem disso, alguns pontos como a origem dos corpos acessórios dos espermatozoides dos Ephemeroptera precisam ser melhor estudados<br>Abstract: Ephemeroptera species are the oldest living winged insects. Their nymphs are aquatic and the adults are short living, dying just after mating. At the present, there are still some doubts about the phylogenetic relationships between Ephemeroptera and the other Pterygota. The morphology of the male reproductive systems and of the spermatozoa is useful to furnish data for phylogenetic studies. However, there are few studies on this subject for Ephemeroptera. This study analyzes the morphology of the male reproductive system and of the spermatozoa of Brazilian Ephemeroptera species.. Species from ten Ephemeroptera families are found in Brazil. In the present study we analyzed the male reproductive system of six species from five families. We also analyzed the sperm morphology of 17 species from nine families. The male reproductive systems analyzed were very similar in the different species, with no accessory glands or specialized organs for sperm storage. However, the intrinsic musculatures of the sperm ducts have different organization patterns, probably related to differences in the reproductive physiology of each species. Greater morphological variation was observed among the spermatozoa. Species from Leptophlebiidae family have aflagellate and immotile spermatozoa. Species from the other families have mobile and flagellate spermatozoa. The organization of the axoneme was the same in all species, with the 9+9+0 microtubule pattern, typical for this insect group. Only the accessory microtubules vary between the 13+7 and the 13+0 subunit patterns. The flagella are characterized by the presence of only one mitochondrion along the flagellum. The accessory bodies morphology may vary between the species and it seems to be correlated to the organization of the mitochondrial cristae and the accessory bodies morphology. The acrosomal vesicles have morphological variations that must be related to differences in the egg chorion thickness. A centriolar adjunct is observed at the flagellum anterior region of the spermatozoa. This structure was thought to be absent in the Ephemeroptera spermatozoa. One species studied has its nucleus laterally associated to the flagellum. Our results suggest that the spermatozoa of Ephemeroptera have enough morphological variation to furnish useful data for future phylogenetic studies. However, more species, representing different groups of the order must be studied, increasing the scope of these studies. Also some questions, such as the origin of the accessory bodies of Ephemeroptera must be further studied<br>Doutorado<br>Biologia Celular<br>Doutor em Biologia Celular e Estrutural

Thesis (MScPhysio (Interdisciplinary Health Sciences. Physiotherapy))--University of Stellenbosch, 2010.<br>ENGLISH ABSTRACT: The pelvic floor muscles (PFM) contribute to urinary continence and overactive PFM seem to be associated with pelvic pain syndrome (PPS). The literature indicates that ethnic differences regarding symptoms of urinary incontinence may exist. Research is needed to establish relationships between PFM function and symptoms reported by women of different ethnic groups. Objectives: To compare the PFM strength and endurance in black, white and coloured women. To investigate relationships between PFM strength, vaginal resting pressures, risk factors and symptoms associated with PFM dysfunction and PPS. Method: A cross-sectional study assessed the PFM strength and vaginal resting pressures of 122 nulliparous black (n=44), white (n=44) and coloured (n=34) university students. A self-developed questionnaire determined inclusion, demographic variables, factors affecting/factors associated with PFM strength and symptoms related to PPS. Maximum voluntary contraction pressure (cmH2O) and vaginal resting pressure (cmH2O) were measured with the Peritron TM 9300 (Cardio Design, Australia) used with the Camtech AS vaginal balloon sensor (Sandvika, Norway). Two sets of 3 maximum voluntary contractions of the PFM were recorded. Results: The mean age of the group was 22 ± 3.54 years and mean BMI of 23± 4.16 kg/m2. Black women (25 cmH2O ± 13.5) had significantly stronger PFM than white (p=0.02) or coloured (p<0.01) women, but no significant difference (p=0.78) in PFM strength existed between white (18.4 cmH2O ± 9.8) and coloured (15.6 cmH2O ± 8) women. In black women, PFM strength decreased significantly (p=0.02) between the sets, whereas no significant difference between sets was noted in the other ethnic groups. Increased PFM strength was associated with SUI (p=0.03) and amenorrhoea (p=0.01) and decreased PFM strength was associated with decreased frequency of bowel motion (p=0.01). In this sample, increased vaginal resting pressure was associated with menorrhagia (p=0.04). Conclusion: Black nulliparous women had stronger PFM than white and coloured women. There was no difference in PFM strength between white and coloured women. Endurance, as measured in this study, indicates that black women have decreased endurance of the PFM compared to white and coloured women. These findings inform the current research on ethnic differences in the prevalence of urinary incontinence. Preliminary data suggest that there was no relationship between vaginal resting pressures and symptoms of PPS and risk factors for PFM dysfunction, except for menorrhagia.<br>AFRIKAANSE OPSOMMING: Die bekkenvloer spiere (BVS) dra by tot urinêre kontinensie en ooraktiewe BVS kan moontlik geassosieer wees met pelviese pyn sindroom (PPS). Uit die literatuur blyk dit of daar etniese verskille bestaan in die simptome van urinere inkontinensie gerapporteer deur vroue. Navorsing is nodig om die verwantskap tussen BVS funksie en simptome wat deur pasiënte van verskillende etniese groepe gerapporteer word vas te stel. Doel: Om „n vergelyking te tref tussen BVS sterkte in swart, wit en kleurling vroue. Om vas te stel of daar assosiasies bestaan tussen BVS sterkte, rustende vaginale druklesings en risiko faktore en simptome geassosieer met bekkenvloer disfunksie en PPS. Metodologie: „n Dwarssnit studie het die BVS sterkte en rustende vaginale drukke van 122 nullipareuse swart (n=44), wit (n=44) en kleurling (n=34) universiteit studente geëvalueer. Insluiting, uitsluiting, demografiese veranderlikes, faktore wat kan affekteer/faktore geassosieer met BVS sterkte en simptome geassosier met PPS is deur „n self ontwikkelde vraelys geëvalueer. Maksimale willekeurige spiersametrekking drukke (cmH2O) en rustende vaginale drukke (cmH2O) was gemeet met „n Peritron™9300 perineometer (Cardio Design, Australië) wat saam „n vaginale ballon sensor (Camtech AS, Sandvika, Noorweë) gebruik is. Twee stelle van 3 maksimale willekeurige sametrekkings van die BVS was gemeet. Resultate: Die groep se gemiddelde ouderdom was 22±3.54 jaar en die gemiddelde liggaamsgewig indeks was 23±4.16kg/m2. Swart vroue (25 cmH2O ±13.5) het beduidend sterker BVS gehad as wit (p=0.02) en kleurling (p<0.01) vroue, maar daar was geen beduidende verskil (p=0.78) in BVS sterkte tussen wit (18.4 cmH2O ± 9.8) en kleurling (15.6 cmH2O ± 8) vroue nie. Die BVS sterkte in swart vroue het beduidend (p=0.02) verminder tussen die stelle, maar geen beduidende verskille was waargeneem in die ander etniese groepe tussen stelle. Verhoogde BVS sterkte was geassosieer met druklek (p=0.03), amenorrhoea (p=0.01) en verminderde BVS sterkte was geassosieer met verminderde frekwensie van opelyf (p=0.01). Verhoogde rustende vaginale drukke was geassosieer met menoragie in hierdie steekproef. Gevolgtrekking: Swart nullipareuse vroue het sterker BVS gehad as wit en kleurling vroue, Daar was geen verskil in BVS sterkte tussen wit en kleurling vroue nie. Uithouvermoë soos in hierdie studie getoets toon dat swart vroue verminderde uithouvermoë het i.v.m. wit en kleurling vroue. Hierdie bevindings dra by tot die huidige navorsing oor etniese verskille in die prevalensie van urinêre inkontinensie. Daar was geen verwantskap tussen vaginale rustende drukke en simptome van PPS en risiko faktore vir die ontwikkeling van bekkenvloer disfunksie, behalwe vir menoragie.

Full textAbstract:
In the present work I analysed different aspects of the evolution of genus Limnebius (Coleoptera, Hydraenidae), including its molecular evolution using mitochondrial (COI, 16S, tRNA-leu, NAD1) and nuclear markers (18S, 28S) as well as morphological data, for which I measured more than 3000 exemplars from 123 species. The study concentrated on the shape of the male genitalia, as the species of Limnebius are extremely uniform in their external characters. In the molecular phylogeny, which included 65 species and was obtained with BEAST, there were two principal branches, coinciding with the ancient separation into two subgenera. In the one of those subgenera, Limnebius s.str., the male genitalia have an extreme variability, with from one up to seven appendages. Other than the median lobe with the spermiduct and the lateral lobes (parameres) typical of the genitalia of Coleoptera, there are up to four additional appendages, sometimes crossing each other. In the second subgenus, Bilimneus, except for one species male genitalia consist only of the median lobe. Other than differences in the male genital structure, Limnebius s.str. is more variable in body size and sexual dimorphism: in this subgenus males could be bigger or smaller than females, while among Bilimneus males are always smaller, and have no secondary sexual characters. In general a large body size is associated with larger males, presence of secondary sexual characters such as modifications of the abdomen or posterior tibias, and more complexity of the male genitalia. There are, however, some exceptions caused by secondary loss of characters, first of all, according the phylogenetic reconstructions, large body size. The size of the male genitalia is also associated with its complexity, but less than with body size, and with more random evolutionary changes. The reconstruction of the ancestral body size for each of the subgenera show that in the origin it was larger in Limnebius s.str. than in Bilimneus, and this could be the reason for the differences in evolution. This reason may not be sufficient, but we have no other evidence for the differences between the evolution of the two subgenera. Differences could also be due to the structure of the parameres, which in Limnebius s.str. are separated from the medial lobe, but we have no precise data to support this hypothesis. The complexity of the male genitalia in Limnebius s.str. evolved in two different forms, with different consequences for the morphological changes: in one (L. parvulus group) its seems that size of the body and genitalia increased before the complexity, and in the other (L. nitidus group) it seems that the complexity is less dependent on the size. Complexity was secondarily lost in one of the subgroups, which could be an indication of character saturation. Other than these differences there are also structural difference in complexity, formed by structures completely different between the two groups. Their homology is possible, but it is not obvious even in the histological serial sections.<br>En la presente tesis he analizado varios aspectos de la evolución del genero Limnebius (Coleoptera, Hydraenidae): molecular (utilizando los marcadores mitocondriales COI, 16S, tRNA-leu, NAD1 y los nucleares 18S y 28S) de 65 especies y morfológica, utilizando mas de 3,000 ejemplares de 123 especies. En el árbol molecular hay dos ramas principales que coinciden con la antigua separación en dos subgéneros: Limnebius s.str., cuya genitalia masculina tiene una enorme variabilidad, con desde uno hasta 7 apéndices; y Bilimneus, que con la excepción de una especie sólo tienen la pieza principal por donde pasa el espermiducto. Limnebius s.str varía más en el tamaño del cuerpo y en el dimorfismo sexual: los machos pueden ser mas pequeños o mas grandes de las hembras, mientras que en Bilimneus los machos siempre son más pequeños y sin caracteres sexuales secundarios. El cuerpo grande está asociado a machos más grandes, presencia de caracteres sexuales secundarios, como modificaciones en el abdomen y en las tibias posteriores, y una mayor complejidad de la genitalia masculina. Hay pérdidas de complejidad secundarias, sobre todo del tamaño del cuerpo. El tamaño de la genitalia masculina esta asociado con su complejidad, pero menos que el tamaño del cuerpo, y cambia de forma más aleatoria. La reconstrucción del tamaño del cuerpo ancestral muestra que en su origen Limnebius s.str. era más grande que Bilimneus, lo que podría ser la razón de las diferencias en su evolución, así como la estructura de los parámetos, que en Limnebius s.str. están siempre más o menos separados de la pieza principal. La complejidad de la genitalia en Limnebius s.str. evolucionó de dos formas distintas, con diferentes consecuencias para los cambios morfológicos: en una (grupo de L. parvulus) el tamaño de cuerpo y la genitalia parece que aumentan antes que la complejidad, y en la otra (grupo de L. nitidus) parece que la complejidad depende menos del tamaño, aunque en uno de los subgrupos se pierde, lo que puede ser una indicación de su saturación. Hay estructuras aparentemente completamente diferentes entre estos dos grupos, cuya homología es posible pero no se puede apreciar en cortes histológicos.
