Sicyos deppei G. Don (Cucurbitaceae) is an invasive monoic annual tendril-bearing vine; it is endemic to Mexico, adapted to the rainfall cycle (June through the end of September) and produces spiny, single seeded fruits. Under serious infestation conditions, S. deppei grows extensively, covering native plants, crops and tree trunks. This study determined the breeding system and pollinators of S. deppei growing in three study sites at urban gardens and disturbed sites at the Campus of the Universidad de las Américas, Puebla in the city of San Andrés Cholula, Puebla (Mexico). Each female inflorescence had an average of 17 flowers at the three study sites. As a step prior to experiments, the timing for stigma receptiveness and pollen viability was determined with the Peroxtesmo KO test (PKO) and Diaminobenzidine test (DAB),respectively. Stigmas of female flowers reach maximum receptivity when flowers are at anthesis; receptivity decreases as the flower reaches the succeeding floral stages. Viability of pollen grains increases with flower development; viabilitypercentages at early stages of floral development are very low, as opposed to the higher percentages of pollen viability found in flowers at anthesis and following developmental stages. Breeding systems were tested for xenogamy and geitonogamy by hand pollinating female flowers. Breeding systems results demonstrated that S. i deppei has a mixed-mating system, being able to set fruit and seed when pollinated with pollen from different plants and from pollen of the same plants. The pollinators were determined with the single-visit method. The diversity of floral visitors in this study was low; the most effective pollinator for S. deppei in this study was Apis mellifera. Throughout the rainy season, this study also described the phenology of S. deppei at the plant and flower level, as well as total plant length. Each stage of development in male and female flowers lasts one day. At the end of the rainy season (N2010) individual plants measured between 947 and 270 cm. / CONACYT, NSERC-CANPOLIN

Sociometer Theory (Leary & Downs, 1995; Leary, Tambor, Terdal, & Downs, 1995) proposes that state self-esteem is a gauge of social inclusion. Expansions to this theory by Kirkpatrick and Ellis (2001) suggest that this is a domain specific process with different sociometers for different adaptive domains. Two studies were conducted to test predictions derived from the domain specific sociometer model of self-esteem proposed by Kirkpatrick and Ellis (2001). In Study 1, participants (N = 83) who were currently single, received feedback to indicate either acceptance (inclusion) or rejection (exclusion) for a potential dating situation. The results indicated that participants who were accepted versus rejected reported increases in state self-esteem and higher mating aspirations. The same effects were not present for either friendship aspiration or friendship investment, indicating domain specificity. The effect of the manipulation on mating aspirations was also significantly mediated by state self-esteem. Study 2 replicated Study 1 using participants (N = 81) who were currently in an intimate relationship. The results indicated that participants who were accepted versus rejected reported increases in state self-esteem and decreases in perceived relationship quality (commitment and satisfaction). The same effects were not present for either friendships aspirations or friendship investment. The association between the manipulation and resulting changes in perceived relationship quality were significantly mediated by state self-esteem, with state self-esteem acting as a suppressor. The results from both studies support a domain-specific conceptualisation of sociometer theory.

The freshwater prawn, Macrobrachium rosenbergii (de Man, 1879) is an important aquaculture species but one that has the disadvantage of heterogeneous individual growth (HIG) according to different morphotypes. Chemical cues, especially, pheromones, are one of the most important communication types between individual prawns, along with visual and tactile methods. Testing pheromones, whilst restricting other cues, may therefore lead to a better understanding of the influence of these communicatory compounds on the prawn reproductive process. The three principle objectives of this study were therefore: 1) To examine the effect of moult stage and morphotype on pheromone-induced sexual behaviour 2) To examine the role of pheromone / urine concentrations on sexual attraction behaviour 3) To describe the functional morphology of the antennal gland and examine its possible role in pheromone production and release. Identical bioassay tanks were designed and constructed to study the reproductive behaviour of prawns. Experiments were set up to examine responses to pheromone release by live prawns over 30 minutes and behavioural response observations were made with the aid of a Closed-Circuit Videotape System (CCVS). Results were statistically analysed using a repeated measures general linear model (GLM). Three trials were designed to test the effect of moult stage of both males and females and male morphotypes on sexual attraction behavioural responses. Twelve prawns were used for each trial and each prawn was used five times (1 no-pheromone control and 4 for experimental tests). The first trial studied the effect of female moult stages (pre-, inter and newly-moulted) on sexual attraction behaviour of blue claw (BC) male. Results of this trial showed that newly-moulted females spent significantly (p<0.05) less time approaching the BC male than the pre- and inter-moult females. The second trial studied the effect of male moult stage (pre-, inter and newly-moulted) on sexual attraction to receptive females. Results showed that the time taken by the inter-moult males was (p<0.05) less than the pre- and newly-moulted males in approaching the newly-moulted female. The third trial tested the effect of male morphotypes (small male, SM, orange claw, OC and dominant blue claw, BC) on sexual attraction behaviour towards newly-moulted females. Results showed that the BC male was significantly more attractive (p<0.05) than other morphotypes to newly-moulted females and that the OC male was the least attractive. The role of moulting stage for both male and female prawns on reproductive response behaviour was investigated. Because BC males responded significantly faster towards newly-moulted female more than to either pre-or inter-moult females, results of the first trial suggest that BC males are able to use different chemical cues to gather information about a conspecific’s gender and can differentiate female’s moult stages. Since BC males responded significantly faster towards newly-moulted females more than to either pre-or inter-moult females, this suggests that females at this particular stage released a distinct sexual pheromone or concentration of pheromone that differed from those pheromones released by both pre- and inter-moult females. In contrast, newly-moulted females prefer the inter-moult BC males which indicate that females have an ability to distinguish the moult status of BC males. Furthermore, it indicates that pheromone characteristics change with the moult status of BC males. Also, newly-moulted females are most likely to be avoiding the potential costs of mate guarding with soft shell BC males. Results obtained from the third trial suggested that a newly-moulted female can discriminate male morphotypes (SM, OC and BC) from their pheromone cues. This indicates that male morphotypes release pheromones which differ from each other in some way. Newly-moulted females responded positively to both SM and BC males with different levels of attraction with the greatest attraction to BC males to BC males suggesting that pheromone released from the BC male may carry information relating to dominance status. Urine is believed to be one of the main carriers of pheromone and is usually released from the antennal gland. Different urine concentrations (0.1, 1.0, 2.0, 3.0, 5.0 and 10µl l-1) of collected urine from BC males were used to test the sexual attraction behaviour of receptive newly-moulted females. Also, the attractant capability of fresh urine following exposure to different temperature regimes (cooled at 4ºC, frozen at -70ºC and heated at 70ºC) was tested. Since newly-moulted female M. rosenbergii were attracted to BC male urine, this indicates the existence of sex pheromone in the fresh urine. Also, it was found that the sexual response of females to fresh urine of BC males was directly proportional to urine concentration with faster responses observed with increasing urine concentrations. At the three fresh urine concentrations 0.1 µl l-1, 1.0 µl l-1 and 2.0 µl l-1, statistical analysis indicated no significant difference (p>0.05) between these three concentrations while a significant (P<0.05) response was to concentrations more than 3.0 µl l-1. This may indicate that these three concentrations were not sufficient to elicit attraction behaviour in newly-moulted females. A concentration of 3.0 µl l-1 of fresh urine is suggested to be a sufficient concentration to elicit a significant sexual attraction under laboratory conditions. Response of newly-moulted female prawns to the various temperature treatments tested declined in response to nominally increasingly degradative treatments. Also, statistical analysis showed that temperature treatment and concentration added both had a significant effect on the response of females. The greatest degradation of urine attractiveness was found with the 70ºC heat treatment. It can be concluded that the pheromone components of prawn urine are friable when exposed to high temperatures. Using light and transmission electron microscopes, ultrastructural observation of the antennal gland (AG) of M. rosenbergii suggests that it has four distinct regions, the coelomosac, the nephridial tubules, the labyrinth and the bladder. Morphological and functional descriptions of each of these regions were compared with those of other aquatic Crustacea.

Habitat fragmentation can have an impact on a wide variety of biological processes including abundance, life history strategies, mating system, inbreeding and genetic diversity levels of individual species. Although fragmented populations have received much attention, ecological and genetic responses of species to fragmentation have still not been fully resolved. The current study investigated the ecological factors that may influence the demographic and genetic structure of the giant white-tailed rat (Uromys caudimaculatus) within fragmented tropical rainforests. It is the first study to examine relationships between food resources, vegetation attributes and Uromys demography in a quantitative manner. Giant white-tailed rat densities were strongly correlated with specific suites of food resources rather than forest structure or other factors linked to fragmentation (i.e. fragment size). Several demographic parameters including the density of resident adults and juvenile recruitment showed similar patterns. Although data were limited, high quality food resources appear to initiate breeding in female Uromys. Where data were sufficient, influx of juveniles was significantly related to the density of high quality food resources that had fallen in the previous three months. Thus, availability of high quality food resources appear to be more important than either vegetation structure or fragment size in influencing giant white-tailed rat demography. These results support the suggestion that a species’ response to fragmentation can be related to their specific habitat requirements and can vary in response to local ecological conditions. In contrast to demographic data, genetic data revealed a significant negative effect of habitat fragmentation on genetic diversity and effective population size in U. caudimaculatus. All three fragments showed lower levels of allelic richness, number of private alleles and expected heterozygosity compared with the unfragmented continuous rainforest site. Populations at all sites were significantly differentiated, suggesting restricted among population gene flow. The combined effects of reduced genetic diversity, lower effective population size and restricted gene flow suggest that long-term viability of small fragmented populations may be at risk, unless effective management is employed in the future. A diverse range of genetic reproductive behaviours and sex-biased dispersal patterns were evident within U. caudimaculatus populations. Genetic paternity analyses revealed that the major mating system in U. caudimaculatus appeared to be polygyny at sites P1, P3 and C1. Evidence of genetic monogamy, however, was also found in the three fragmented sites, and was the dominant mating system in the remaining low density, small fragment (P2). High variability in reproductive skew and reproductive success was also found but was less pronounced when only resident Uromys were considered. Male body condition predicted which males sired offspring, however, neither body condition nor heterozygosity levels were accurate predictors of the number of offspring assigned to individual males or females. Genetic spatial autocorrelation analyses provided evidence for increased philopatry among females at site P1, but increased philopatry among males at site P3. This suggests that male-biased dispersal occurs at site P1 and female-biased dispersal at site P3, implying that in addition to mating systems, Uromys may also be able to adjust their dispersal behaviour to suit local ecological conditions. This study highlights the importance of examining the mechanisms that underlie population-level responses to habitat fragmentation using a combined ecological and genetic approach. The ecological data suggested that habitat quality (i.e. high quality food resources) rather than habitat quantity (i.e. fragment size) was relatively more important in influencing giant white-tailed rat demographics, at least for the populations studied here . Conversely, genetic data showed strong evidence that Uromys populations were affected adversely by habitat fragmentation and that management of isolated populations may be required for long-term viability of populations within isolated rainforest fragments.

No. of bitstreams: 1 texto completo.pdf: 315546 bytes, checksum: 7c3954ee8525d69ec5427b4b0a3dbabb (MD5) Previous issue date: 2006-02-23 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The present thesis had the aim to study the importance of the host plant to the reproductive behavior of L. coffeella. At first, the following aspects were evaluated: (i) the effect of the reproductive condition of females in response to host plant volatiles; (ii) if mating proportion, initiation time and copulation duration are affected by the presence of volatiles in the host plant; (iii) and if females of L. coffeella, under no choice conditions, may be able to lay eggs in an alternative host. The efficiency of the mating disruption technique of males as a control method for this insect was also studied. In addition, the efficiency of PB-Rope dispensers was tested under low population conditions of adults in the field. These PB-Rope dispensers were used in order to saturate the environment with synthetic sexual pheromone and consist of a polyethylene tube containing 200 mg of 5,9-dimethylpentadecane, produced by Shin-Etsu Chemical Co. Ltd (Tokyo, Japan). In order to do so, the following hypotheses were tested: (i) that the PB-Rope dispenser provokes disorientation in males of L. coffeella in the areas treated with pheromone and (ii) that mating disruption leads to a decrease of lesions caused to the genus L. coffeella. In the first work, it was evidenced that only the volatiles emitted by the plant do not comprise relevant clue for females to spot their host. Nevertheless, they play an important role during the mating process. When another non-host plant was offered to the females as an oviposition site, it was observed that there was a considerable reduction in the number of laid eggs, indicating that females use cues of the host plant for oviposition. In the second work, the number of males captured in the pheromone traps in the treated area was reduced in relation to the control areas; however, the damage that this insect causes to the plantation was not different between the treated areas and the control areas. In this case, it was not possible to quantify the efficiency of the technique because the same levels of mined leaves and eggs were found in both areas. / Nesta tese foi estudada a importância da planta hospedeira no comportamento reprodutivo de L. coffeella. Inicialmente avaliou-se: (i) o efeito da condição reprodutiva das fêmeas em resposta aos voláteis da planta hospedeira; (ii) se a proporção de acasalamento, tempo de início e duração da cópula são afetadas pela presença de voláteis da planta hospedeira; (iii) e se fêmeas de L. coffeella, em condições de não escolha, podem ovipositar em hospedeiro alternativo. Foi estudada também a eficiência da técnica de confusão sexual de machos como método de controle deste inseto. Foi testada a eficiência dos liberadores de feromônio PB-Rope em condições de baixa população de adultos em campo. Estes liberadores PB-Rope foram usados para saturar o ambiente com feromônio sexual sintético e consistem de um tubo afilado de polietileno contendo 200 mg de 5,9-dimetilpentadecano, fabricados pela Shin-Etsu Chemical Co. Ltda (Tókio, Japão). Para isto testaram-se as hipóteses: (i) de que nas áreas tratadas com feromônio, o liberador PBRope provoca desorientação nos machos de L. coffeella e (ii) que a confusão sexual leva a redução das injúrias causadas ao cafeeiro por L. coffeella. No primeiro trabalho, ficou evidenciado que os voláteis sozinhos emitidos pela planta não constituem pista relevante para as fêmeas localizarem seu hospedeiro, porém têm papel importante durante o acasalamento. Quando ofereceu-se às fêmeas outra planta não hospedeira como sítio de oviposição, pode-se observar uma redução considerável no número de ovos depositados, indicando que as fêmeas usam pistas da planta hospedeira para a oviposição. No segundo trabalho, o número de machos capturados nas armadilhas de feromônio nas áreas tratadas foi reduzido em relação às áreas controles, mas, o dano deste inseto à lavoura não foi diferente entre as áreas tratadas e áreas controles. Neste caso, não foi possível quantificar a eficiência da técnica porque os mesmos níveis de folhas minadas e ovos foram encontrados em ambas as áreas.

The intracellular proteolysis of ingested meal plays an essential role in tick development. The thesis focuses on the factors influencing the expressions and activities of digestive enzymes in Ixodes ricinus females during the feeding and post-feeding period. We have revealed the effect of fertilization on blood feeding and digestion. The females cannot reach the rapid engorgement phase without being fertilized. The rate of mated females in the nature proved the presumption that mating can occur even off the host. Implementation of in vitro feeding technique further extended our current knowledge about tick digestive apparatus. Adult females were fed on hemoglobin-rich and hemoglobin-poor diet and the mRNA expression levels of digestive proteases were determined. In line with obtained data, we assumed that albuminolysis is conducted by the same or similar pathway as hemoglobinolysis. The gene silencing method and protein immuno-detection were used to unequivocally identify the isoforms of 'early expressed' IrCL1 and 'late expressed' IrCL3 isoform of cathepsin L.

To motivate my analysis, I document a positive cross-country correlation between intergenerational persistence of income (and education) and educational assortative mating. I then develop an overlapping generations model in which parents invest in their children's education and individuals choose whom they are going to marry, and estimate the model to fit the postwar U.S. data. My results suggest that both of these changes have affected the intergenerational earnings persistence, but that the marriage decision plays only a very small role in these results.

In this thesis we aim to analyze how agents’ decisions on marriage and education can be interconnected assuming that men and women have preferences for intra-group marriage. In our framework we find that preferences for intra-group marriage can increase the proportion of men and women who decide to get married and study. We also show that empirically for Brazilian data there is a positive assortative mating between people with same traits, such as, education, religion or race. In addition, married couples that share the same religion tend to have the same level of schooling. We investigate how changes in marital sorting, educational composition and returns to education that occurred in Brazil in the last years can impact in household income inequality. We calculate counterfactual scenarios for Gini Coefficient keeping one of these three variables fixed in one year and comparing the counterfactual values with the actual one. If marriage were formed randomly, the Gini Coefficient would be lower than the actual one. Keeping the returns to education fixed in year 2014 we also show that the counterfactual Gini would be lower than the actual one. / A sociedade mudou nas últimas décadas abrindo a possibilidade para cientistas sociais estudarem essas mudanças e analisar os seus impactos na unidade familiar. Nesta tese pretendemos analisar como as decisões dos agentes com relação a decisão de casar e estudar pode estar conectado considerando que homens e mulheres têm preferências pelo casamento intragrupo. No modelo estudado encontramos que as preferências para o casamento intragrupo podem aumentar a proporção de homens e mulheres que decidem se casar e estudar. Mostramos também que empiricamente há um positive assortative mating entre pessoas com as mesmas características, tais como, educação, religião ou raça. Além disso, a probabilidade de casais casados na mesma religião aumenta a probabilidade dos casais estarem casados dentro do mesmo nível de escolaridade. Considerando as mudanças em como os casais se formam, a composição educacional e os retornos da educação que aconteceram no Brasil nos últimos anos, investiga-se os impactos dessas mudanças na desigualdade de renda dos casais. Calculamos cenários contrafactuais para o Coeficiente de Gini mantendo uma dessas três variáveis fixas em um determinado ano, comparando o contrafactual estimado com o Gini real. Se o casamento for formado aleatoriamente com relação à educação, o Coeficiente de Gini seria menor do que o real. Mantendo os retornos da educação fixos no ano de 2014 encontramos um Gini contrafactual menor do que o real.

Allemão). O estudo foi conduzido na Estação Ecológica de Paulo de Faria (435,73 ha), onde a população da espécie em estudo ocupa uma área aproximada de 142 ha. Todas as 467 árvores adultas encontradas foram amostradas, tiveram o diâmetro à altura do peito (DAP a 1,3 m) medido e foram mapeadas. Adicionalmente amostraram-se 149 regenerantes e 514 progênies de polinização aberta, coletadas de 30 árvores matrizes da população. Sobre a amostra total de cinco locos em 1130 genótipos (adultos + regeneração + progênies) foram observados 60 alelos, o que sugere um nível de polimorfismo relativamente alto. O número de alelos por loco variou de 7 a 25, com média de 12 alelos por loco. A heterozigosidade esperada média em equilíbrio de Hardy-Weinberg foi de 0,662, enquanto que a heterozigosidade observada foi de 0,713. O índice de fixação variou de -0,348 a 0,215 entre locos, com média de -0,076, sugerindo excesso de heterozigotos. A análise da distribuição espacial dos genótipos indicou a presença de estrutura genética espacial (EGE) na população adulta até aproximadamente 40 m e nos regenerantes até aproximadamente 30 m. Foram detectados cruzamentos entre parentes, pela diferença entre a unidade e a taxa de cruzamento uniloco (st1=0,019, P<0,05). A estimativa da correlação de paternidade ()(mpr) indicou que as progênies são compostas por misturas de meios-irmãos e irmãos-completos, embora estes últimos em menor proporção (média de 0,158) O coeficiente de coancestria (Θxy) dentro das progênies... / The aims of this study were to investigate for microsatellites loci the genetic diversity, mating system, the intrapopulational spatial genetic structure, the distance and patterns of pollen dispersal, and the dynamics of inbreeding among generations, in a fragmented population of the dioicious tropical tree Myracrodruon urundeuva (F.F. & M.F. Allemão). The study was carried out in the Paulo de Faria Ecological Station (435.73 ha), where the studied population occupies about 142 ha. All 467 adult trees found in the stand were sampled, have the diameter at breast height (D.B.H of 1.3 m) measured and were mapped. Additionally 149 juveniles and 514 open-pollinated offspring from 30 seed-trees were sampled in the population. On the total of five loci sampled in 1135 genotypes (adults + juveniles + offspring), 60 alelos were detected, suggesting a relative high level of polimorphis. The number of alleles per locus ranged from 7 to 25 alleles, with average of 12 alleles. The average expected heterozygositys in Hardy-Weinberg equilibrium was of 0.662, were the average observed heterozygosity was of 0.713. The fixation index ranged among locus from -0.348 to 0.215, with average of -0.076, suggesting excess of heterozygous. The analysis of the intra-population spatial genetic structure (SGS) detected the presence of SGS in adults until about 40 m and in juveniles until about 30 m. Mating among relatives were also detected by the difference between the unit and the single-locus outcrossing rate ( s t 1 =0.019; P<0.5). The paternity correlation ( p (m ) r ) indicated that the offspring were composed by mixtures of half-sibs and full-sibs, where the last one occurred in low frequency (average of 0.158). The coancestry coefficient (Θxy) within families was larger than expected in half-sibs (Θxy=0.125), with population average of 0.150. The variance effective population size (eN) within...
