Abstract:
A particularly interesting aspect of the study of organisms in insular environments is plant reproduction and the interaction of plants with their pollinators. Differences in composition between the fauna and flora of continental and island populations, combined with their geographical isolation, have frequently driven rapid evolution in colonizing populations. In particular, floral traits and compatibility systems tend to favour autogamy in response to a paucity of pollinators in the environment. In this context we investigate the origins of the reproductive biology of Aloe mayottensis Berger, a lily endemic to the island of Mayotte. We show that this species is pollinated by the island's endemic sunbird species, and has floral traits and a reproduction system that favour allogamy. Our results show that A. mayottensis is a protandrous and partially self-compatible species. Analysis of stigmatic pollen load shows that stigma received a mean of 56 crossed pollen grains and 62.2 selfed pollen grains per stigma. Study of visitation rates of plants and flowers by the sunbird showed that there is daily variation in the activity of this pollinator, and that males are more active than females.Key words: Aloe mayottensis, floral biology, Lomatophyllum, Nectarinia, bird pollinization, sunbirds, Oceanic islands, Mayotte.

Abstract:
The study of reproduction of Pseudotolithus elongatus in the Ebrie lagoon was investigated between July 2013 and June 2015 on a whole of individuals of 550 specimens. the total length ranges from 14.5 to 42.7 cm. The monthly evolution of the gonado-somatic index (GSI), the liver-somatic index (LSI), the condition factor (K), the Sex-ratio, the fecundity, the diameter of eggs revealed that this species spawns throughout the year but the main breeding period was in raining season. Sex-ratio observed was in favour of females (1: 1. 14; X2 = 2.26; p > 0.05). The percentage of mature specimens by sexes was calculated for each size class. Total length at first maturity was 21.06 cm for females and 20.21cm for males. The ripe ovaries contained 39883-814757 eggs. The relative fecundity was 216-1979 eggs per g of body weight of females. And the mean diameter of eggs is 336 ±138 microns.

Abstract:
L'Atipa, Hoplosternum littorale, Siluriforme à plaques osseuses de la famille des Callichthyidae, est un poisson qui peuple les marais hypoxiques d'une aire de répartition qui s'étend de Trinidad au Paraguay. Son comportement reproducteur est original: la ponte de une ou plusieurs femelles est déposée dans un nid de bulles et de débris végétaux construit et gardé durant toute la durée des incubations par le mâle. Les travaux présentés dans cette thèse ont été réalisés en milieu naturel et en étang. L'observation du comportement reproducteur, le dénombrement et la localisation des nids construits en étang, l'évaluation du poids des pontes individuelles ou collectives, l'enregistrement de l'évolution des valeurs du Rapport Gonado-Somatique au cours du cycle annuel et de celui de la température dans les nids, ont permis: ― La mise en évidence d'un choix de la localisation du nid et de l'heure de la ponte au cours du cycle nycthémèral. ― Une description du cycle annuel de reproduction de l'espèce en pisciculture, et la confrontation de ses caractéristiques à celles établies en milieu naturel. ― Une tentative de quantification des performances de ponte et d'évaluation de l'investissement parental au cours d'une saison de reproduction. ― Une caractérisation des paramètres thermiques de l'incubation en milieu contrôlé et dans les nids construits en étang. ― La mise en évidence de l'influence des conditions thermiques durant l'incubation sur la valeur du sexe-ratio. Ces résultats, conduisent à proposer une vision de la stratégie de reproduction de l'Atipa, à évaluer l'intérêt du modèle biologique que constitue ce poisson pour l'étude de l'influence des conditions thermiques durant l'incubation sur les variations du sexe-ratio et à évoquer les applications piscicoles qu'ils suggèrent

Abstract:
Le paradigme unique du travail experimental fait intervenir le risque inherent a un certain nombre de ruptures dans le developpement + spontane ; de l'individu (insemination artificielle, pollution, manipulation genetique). Dans tous les cas et dans les deux ordres possibles, on fait mesurer a chaque sujet les risques que courraient, dans cette situation, d'une part l'enfant a naitre et d'autre part, a long terme, "l'espece humaine". Dans une premiere experimentation, on etablit que l'espece humaine apparait toujours comme courant plus de risques que l'individu a naitre et que l'evocation prealable des risques courus par + l'espece humaine ; fait percevoir comme plus importants les risques courus par l'individu (non reversible). Dans une seconde experimentation, on cherche a etablir que si l'on renforce la representation de donnees biologiques dans la perpetuation de l'espece humaine (vs non- renforcement) ce modele n'apparait plus que de facon allusive. Dans une troisieme experimentation, si on oppose a ce renforcement la representation de valeurs culturelles liees a la representation de la perpetuation de l'espece, c'est seulement dans ce dernier cas que le modele primitif se retrouve. Dans une quatrieme experimentation, on confirme que chez le sujet feminin la representation de la biologie dans la procreation inclut deja des elements culturels et axiologiques que l'un ne retrouve pas chez le sujet masculin
The single paradigm of this research refers itself to the inherent risk of some breaking off in human being natural development (artificial insemination, pollution, genetic manipulation). In any case and in the two different possible orders, the subjects who answered the questionnaire had to assess the risks for the child to be born and for the + species to be ; long dated. In the first experimentation, the + species to be ; is seen as running more risks than the individual to be born and the risks run by individual to be born are seen as greater when the risks run by +the + species ; have been previously assessed (the reverse is not true). In the second experimentation, we try to build up that if we strengthen the representation of biological aspects in species perpetuation (vs non strengthening), this mode is only allusive. In the third experimentation, if we oppose to this strengthening the representation of cultural aspects in species perpetuation, it's in this second case only that we find again the original model. In the fourth experimentation, we confirm that when the subjects answering are females, the representation of biology in the procreation already include some cultural and axiological elements (that is not true when the subjects answering are males)

Abstract:
Chez de nombreux organismes, on assiste à une augmentation du succès reproducteur avec l’âge. Cependant, les mécanismes physiologiques impliqués restent mal connus. Ce doctorat a pour objectif d’explorer chez des oiseaux marins l'influence de l'âge sur les mécanismes hormonaux régulant les comportements parentaux, l'allostasie et la réponse au stress (corticostérone et prolactine). Grâce à des suivis démographiques à long terme, nous avons montré que l’âge et l’expérience de reproduction influençaient les taux basaux de ces hormones et la sensibilité au stress. De plus, nous avons décrit les corrélats hormonaux du phénomène de sénescence. Nous avons montré le rôle de la corticostérone, qui régule en interaction avec la condition corporelle, l'effort de recherche alimentaire et les décisions de reproduction. Enfin, nous avons montré que les variations des taux de corticostérone et de prolactine constituaient l'une des causes fonctionnelles de l'influence de l'âge sur le succès reproducteur. Nous discutons de la contribution possible de cette exploration hormonale dans l'origine évolutive des relations entre âge et succès reproducteur
Breeding success increases with age in many organisms, but the physiological mechanisms underlying this pattern are poorly known. The aim of this dissertation is to explore the influence of age on hormonal mechanisms involved in the regulation of parental behaviour, allostasis and stress response (corticosterone and prolactin) in seabirds. The use of ongoing long-term mark-recapture programme allowed us to show that age and especially breeding experience influence baseline hormones levels and the sensitivity to stressors. We were able to describe the first hormonal correlates of senescence. We showed the role of corticosterone, which in interaction with body condition, mediates foraging decisions and allocations processes. Our data strongly suggest that variations in baseline corticosterone levels and the ability to maintain a threshold levels of prolactin during a stressful situation may be an important physiological mechanism involved in the improvement of reproductive performance with advancing age. These findings are discussed in the light of current the evolutionary theories addressing the effect of age and experience on reproductive success

Abstract:
Ants and other social Hymenoptera (social bees and wasps) have a remarkable mating strategy. Social Hymenoptera live in societies where reproduction is monopolized by a fertile caste consisting of males and queens. On the other hand, the logistical tasks of the colony are carried out by a sterile female caste known as workers. Reproductive individuals mate during a single bout early in their life and will never engage in additional reproductive events later on. Males die soon after mating while queens store millions of sperm cells in a specialized organ, the spermatheca. Queens will use this sperm stock to fertilize eggs during the rest of their life that can last up to several decades. With a record of 28.5 years in the black garden ant, ant queens have the longest lifespan recorded to date among the social Hymenoptera. In my thesis, I addressed three aspects of ant queen reproduction. First, I tested the effect of mating on the expression of several genes involved namely in fecundity, longevity and immunity. I found that mating induces an up-regulation of the yolk precursor vitellogenin and of the antimicrobial peptide defensin. Second, I measured the intensity of different immune responses in male and queen genital organs in order to determine which immune pathways are activated to protect sperm. Antimicrobial peptide genes are expressed in the genital tract of both sexes and the queen spermatheca is capable of strongly inhibiting bacterial growth. The immune melanization response is, however, overall inactive in the organs tested probably because its unspecific mode of action and cytotoxic by-products are likely to damage sperm cells. Immunity thus seems to be closely regulated in organs that are in contact with sperm. Third, I determined if activation of the queen immune system had an impact on the survival of sperm stored in the spermatheca. There is no detectable effect in young newly mated queens whereas, in one year old queens, immune activation induces a significant reduction in sperm viability. Life stage thus seems to influence queen ability to preserve sperm viability in the event of an immune challenge. In addition, one year old queens have higher sperm viability than newly mated queens suggesting queens are able to displace dead sperm cells from their spermatheca. Finally, I relied on the well-established sequence of behaviors inherent to the early life of ant queens to try to uncover the largely unknown roles of inotocin, the insect ortholog of the vertebrate hormones oxytocin and vasopressin, in regulating insect behavior. I measured gene expression of the inotocin receptor and found that it is highly expressed during social and reproductive behaviors, which is consistent with previous results in vertebrates. Inotocin might thus also be involved in modulating these behaviors in insects, but further studies are needed to be able to fully understand this complex signaling system. Overall, I show that reproduction and immunity are closely linked in ant queens and that the latter provide promising models for investigating the roles of hormones in insects.

Abstract:
La these traite de la reproduction d'une planorbe neotropicale: biomphalaria glabrata. Le premier chapitre est consacre a l'etude de la gonade. Apres une description de l'ovotestis, l'etude de son fonctionnement est aborde par la methode des cultures in vitro. Ensuite, sont etudies les effets de perturbations comme le jeune et les temperatures elevees sur la gonade d'individus jeunes et immatures. Le deuxieme chapitre porte sur les tractus genitaux. Le probleme de la differenciation des tractus et de leur fonctionnement (elaboration des pontes) est aborde par la castration chirurgicale. Il est traite ensuite des perturbations provoquees par le jeune, la dessiccation et les temperatures elevees. Le troisieme chapitre concerne le fonctionnement global de l'appareil genital, a travers sa caracteristique essentielle qui est l'hermaphrodisme. Il est traite du demarrage de l'activite sexuelle, de l'accouplement et des notions de fecondite et de fertilite. Ce chapitre se clot sur l'etude de l'auto- et de l'allofecondation et de leurs consequences sur la reproduction de la planorbe. Le quatrieme chapitre traite, dans diverses conditions experimentales, de l'importance relative des deux modes de reproduction sur les consequences que cela entraine sur les echanges genetiques entre les individus

Abstract:
The successful introduction of promising plant species into the culture, including introducers, is possible on the condition of a deep study of the biology of their development, reproduction, as well as the peculiarities of cultivation and use. Tree and shrub species have a whole range of different abiotic and biotic factors and need to conduct long-term observations, assessment and prediction of their condition. We consider it necessary to conduct an inventory of the woody flora on the territory of our campus and provide data on the state of species in order to improve the microclimate.

Abstract:
The zebrafish (Danio rerio) represents an increasingly popular vertebrate animal model valuable for genetic and developmental biology research, due to its rapid rate of reproduction and the ability to directly observe the growing embryos, which are optically clear and develop ex vivo. However, the need to maintain live stock of each genetic strain (the number of which is growing exponentially) is risky and prohibitively costly. Although long-term banking of frozen embryos would solve this problem, to date, no adequate method for cryopreservation of zebrafish embryos has been found (Hagedorn et al., 2004).

Abstract:
This article presents results of biology research of two species of Scarabaeidae under the conditions of the Republic of Moldova. The Cetonia aurata development cycle takes place within two years, is a monovoltine spring-summer breeder, hibernates in the adultsand sometime in the larval stage. The adults and larvae lives in plant composts, in decomposed foliage, in rotten roots of plants. Adults sometimes attack inflorescences of fruit trees, so they can be considered pests of orchards, but some larvae live in the soil, consume plant remains and plant composts, so this saprofage species is considered and useful. The second species Protaetia affinis affinis is a mesophyla species with summer-autumn reproduction type, hibernates in the adult stage and larvae, lives in deciduous and semi-degraded vegetal debris from deciduous forests, forests strips, orchards. Species do not cause damage to forestry and agriculture.

Abstract:
i. List the original objectives, as defined in the approved proposal, and any revisions made at the beginning or during the course of project. Our objectives were: 1) develop state-of-the-art functional genomics tools for B. terrestris. These resources will be then used to: 2) characterize genes and molecular pathways that are associated with reproduction, 3) characterize genes and molecular pathways associated with specialization in foraging or nursing activities, and 4) determine the extent to which juvenile hormone (JH) is involved in the regulation of reproduction and division of labor. 5) Use RNA interference to down regulate genes associated with reproductive physiology, division of labor, or both. A decrease in the cost of RNA sequencing enabled us to further use the BARD support to extend our research to three additional related projects: A) The regulation of body size which is crucial for understanding both reproduction (castedetermination) and (size based) division of labor in bumblebees. B) Analyze RNA editing in our RNA sequencing data which improves the molecular understanding of the systems we study. C) The influence of JH on the fat body in addition to the brain on which we focused in our proposal. The fat body is a key tissue regulating insect reproduction and health. ii. Background to the topic. Bees are by far the most important pollinators in agricultural and natural ecosystems. The recent collapse of honey bee populations, together with declines in wild bee (including bumble bee) populations, puts their vital pollination services under severe threat. A promising strategy for circumventing this risk is the domestication and mass-rearing of non-Apis bees. This approach has been successfully implemented for several bumble bees including Bombusterrestris in Israel, and B. impatiens in the US, which are mass-reared in captivity. In spite of their critical economic and environmental value, little is known about the physiology and molecular biology of bumble bees. In this collaborative project we developed functional genomics tools for the bumble bee B. terrestris and use these tools for a first thorough study on the physiology and molecular biology of reproduction, dominance, and division of labor in a bumble bee. iii. Major conclusions, solutions. The valuable molecular data of this project together with the functional tools and molecular information generated in this BARD funded project significantly advanced the understanding of bumblebee biology which is essential for maintaining their vital pollination services for US and Israel agriculture.

Abstract:
A fundamental problem in biology is to understand how fertilization initiates reproductive development. During plant reproduction, one sperm cell fuses with the egg to form an embryo, whereas a second sperm cell fuses with the adjacent central cell nucleus to form the endosperm tissue that supports embryo and/or seedling development. To understand the mechanisms that initiate reproduction, we have isolated mutants of Arabidopsis that allow for replication of the central cell and subsequent endosperm development without fertilization. In this project we have cloned the MEA gene and showed that it encode a SET- domain polycomb protein. Such proteins are known to form chromatin-protein complexes that repress homeotic gene transcription and influence cell proliferation from Drosophylla to mammals. We propose a model whereby MEA and an additional polycomb protein we have cloned, FIE , function to suppress a critical aspect of early plant reproduction and endosperm development, until fertilization occurs. Using a molecular approach we were able to determine that FIE and MEA interact physically, suggesting that these proteins have been conserved also during the evolution of flowering plants. The analysis of MEA expression pattern revealed that it is an imprinted gene that displays parent-of- origin-dependent monoallelic expression specifically in the endosperm tissue. Silencing of the paternal MEA allele in the endosperm and the phenotype of mutant mea seeds support the parental conflict theory for the evolution of imprinting in plants and mammals. These results contribute new information on the initiation of endosperm development and provide a unique entry point to study asexual reproduction and apomixis which is expected to improve crop production.

Abstract:
Teaching about relationships and sex in UK schools often focuses on the biology of reproduction. Stakeholders have called for lessons to cover a broader range of issues, such as healthy relationships and the risks posed by using digital technology. The subject Relationships and Sex Education (RSE) will become statutory in all secondary schools in England in the near future. There is ongoing consultation into what will be included in the statutory guidance for RSE. This POSTnote reviews evidence on the potential outcomes of RSE in schools and how to maximise its effectiveness.

Abstract:
Symbiotic bacteria have been shown to influence host reproduction and defense against biotic and abiotic stressors, and this relates to possible development of a symbiont-based control strategy. This project was based on the hypothesis that symbionts have a significant impact on Culicoides fitness and vector competence for animal viruses. The original objectives in our proposal were: 1. Molecular identification and localization of the newly-discovered symbiotic bacteria within C. imicola and C. schultzei in Israel and C. sonorensis in California. 2. Determination of the prevalence of symbiotic bacteria within different vector Culicoides populations. 3. Documentation of specific symbiont effects on vector reproduction and defense: 3a) test for cytoplasmic incompatibility in Cardinium-infected species; 3b) experimentally evaluate the role of the symbiont on infection or parasitism by key Culicoides natural enemies (iridescent virus and mermithid nematode). 4. Testing the role(s) of the symbionts in possible protection against infection of vector Culicoides by BTV. According to preliminary findings and difficulties in performing experimental procedures performed in other insect symbiosis systems where insect host cultures are easily maintained, we modified the last two objectives as follows: Obj. 3, we tested how symbionts affected general fitness of Israeli Culicoides species, and thoroughly described and evaluated the correlation between American Culicoides and their bacterial communities in the field. We also tried alternative methods to test symbiont-Culicoides interactions and launched studies to characterize low-temperature stress tolerances of the main US vector, which may be related to symbionts. Obj. 4, we tested the correlation between EHDV (instead of BTV) aquisition and Cardinium infection. Culicoides-bornearboviral diseases are emerging or re-emerging worldwide, causing direct and indirect economic losses as well as reduction in animal welfare. One novel strategy to reduce insects’ vectorial capacity is by manipulating specific symbionts to affect vector fitness or performance of the disease agent within. Little was known on the bacterial tenants occupying various Culicoides species, and thus, this project was initiated with the above aims. During this project, we were able to describe the symbiont Cardinium and whole bacterial communities in Israeli and American Culicoides species respectively. We showed that Cardinium infection prevalence is determined by land surface temperature, and this may be important to the larval stage. We also showed no patent significant effect of Cardinium on adult fitness parameters. We showed that the bacterial community in C. sonorensis varies significantly with the host’s developmental stage, but it varies little across multiple wastewater pond environments. This may indicate some specific biological interactions and allowed us to describe a “core microbiome” for C. sonorensis. The final set of analyses that include habitat sample is currently done, in order to separate the more intimately-associated bacteria from those inhabiting the gut contents or cuticle surface (which also could be important). We were also able to carefully study other biological aspects of Culicoides and were able to discriminate two species in C. schultzei group in Israel, and to investigate low temperature tolerances of C. sonorensis that may be related to symbionts. Scientific implications include the establishment of bacterial identification and interactions in Culicoides (our work is cited in other bacteria-Culicoides studies), the development molecular identification of C. schultzei group, and the detailed description of the microbiome of the immature and matched adult stages of C. sonorensis. Agricultural implications include understanding of intrinsic factors that govern Culicoides biology and population regulation, which may be relevant for vector control or reduction in pathogen transmission. Being able to precisely identify Culicoides species is central to understanding Culicoides borne disease epidemiology.

Abstract:
As is true for all crops, production of Citrus fruit is limited by traits whose characteristics are the products of many genes (i.e. cold hardiness). In order to modify these traits by marker aided selection or molecular genetic techniques, it is first necessary to map the relevant genes. Mapping of quantitative trait loci (QTLs) in perennial plants has been extremely difficult, requiring large numbers of mature plants. Production of suitable mapping populations has been inhibited by aspects of reproductive biology (e.g. incompatibility, apomixis) and delayed by juvenility. New approaches promise to overcome some of these obstacles. The overall objective of this project was to determine whether QTLs for environmental stress tolerance could be effectively mapped in the perennial crop Citrus, using an extensive linkage map consisting of various types of molecular markers. Specific objectives were to: 1) Produce a highly saturated genetic linkage map of Citrus by continuing to place molecular markers of several types on the map. 2) Exploiting recently developed technology and already characterized parental types, determine whether QTLs governing cold acclimation can be mapped using very young seedling populations. 3) Determine whether the same strategy can be transferred to a different situation by mapping QTLs influencing Na+ and C1- exclusion (likely components of salinity tolerance) in the already characterized cross and in new alternative crosses. 4) Construct a YAC library of the citrus genome for future mapping and cloning.

Abstract:
- Original objectives and revision: The feasibility study performed in the last year was aimed at determining the symbiotic profiles of eight selected Culicoidesspecies in Israel and the USA by: Comparing bacterial communities among geographic populations of primary bluetongue virus (BTV) vectors. Comparing bacterial communities between adults of field-collected, mammal-feeding BTV vectors and non-vectors. Comparing bacterial communities within and between mammal feeders and bird feeders, with special attention to species with unique immature habitats. We made an effort to collect the eight species during the beginning of the project, however, due to the short available collection season, and the significant changes in habitats available for Israeli Culicoides, we initially determined the symbiotic profile of five species: two BTV vectors (C. sonorensis, C. imicola), one mammal feeders with unknown vectoring ability (C. schultzei), one bird feeder (C. crepuscularis), and one unique habitat species (C. cacticola). In addition, upon preliminary symbiont identification we focused our effort on relevant specific symbionts. Background: Biting midges (Culicoides, Diptera: Ceratopogonidae) are vectors of many major viral diseases affecting farm animals, including BT, which is listed among the most damaging by the World Organization for Animal Health (OIE) and has recently emerged in completely unexpected areas (Northern Europe). One of the strategies to reduce the vectorial capacity of insect vectors is by manipulating their specific symbionts either to affect the vector species or to influence performance of the disease agent within it. Despite significant efforts to elucidate the vectorial capacity of certain Culicoidesspecies, and the critical basis of variability in infection, almost no attention has been given to symbiotic interactions between the vector and its bacterial tenants. It is now established that bacterial symbionts have major influences on their host biology, and may interact with disease agents vectored by their hosts. - Major conclusions, solutions, achievements: During the feasibility project we have found two major bacterial symbionts in Israeli and American Culicoides. In Israel we discovered that C. imicola, a known vector of BT, and C. schultzeigp. a suspected vector of BT, carry the symbiotic bacterium Cardinium, a reproductive manipulator symbiont. In C. imicolathe infection rate was close to 50%, and in C. schultzeiit was lower, and restricted to one of two species within Schultzeigroup. In 3 American species (C. sonorensis, C. crepuscularis, C. cacticola) we found the bacterium Burkholderiasp. In all species tested we have also found other bacterial species in diverse quantities and frequencies. - Implications, both scientific and agricultural: Finding specific symbionts in Culicoidesvector species is the first step in developing symbiont based control (SBC) strategies. Both identified symbionts are known from other insects, and Cardiniumis also known as a reproductive manipulator that can cause cytoplasmic incompatibility, an important phenomenon that can be used for spreading desired traits in infected populations. The role of the symbionts in Culicoideshost can be target for manipulation to reduce the vectorial capacity of the host by either changing its fitness so that it is unable to serve as a vector, or by directly changing the symbiont in a way that will affect the performance of the disease agent in its vector. Since Burkholderiaperhaps can be cultured independently of the host, it is a promising candidate for the later option. Thus, we have now opened the door for studying the specific interactions between symbionts and vector species.
