Texte intégralTransposable elements (TEs) are universal components of all living organisms. TEs activity and movement have profound effects on host genome and today many researchers agree to consider them as important actors in genome evolution. The relationships between TEs and their host genomes are still under debate. Different hypotheses were proposed to explain TEs dynamics in host genome; one of these propose that host reproductive strategies can influence TEs evolutionary dynamics (Hickey, 1982). In fact, bisexual organisms, through homologous chromosomes recombination and reassortment during meiosis and amphimixis, can control the spread and proliferation of mobile elements, while unisexual organisms would experience an increase of these elements density due to the inability to eliminate them through exclusive mechanisms of sexual reproduction. In order to evaluate these hypothesis, I isolated and characterized TEs in organisms with non-canonical reproductive strategies. I performed my analyses in two organisms: the stick insects of the Bacillus genus and in the tadpole shrimps T. cancriformis. In both instances reproductive strategies range from bisexual gonochoric reproduction, to unisexual parthenogenesis, making them an excellent model for the study and characterization of TEs. In the Bacillus genus I focused on the R2 non-LTR retrotranposon. I isolated and sequenced by primer walking seven R2 complete elements; both gonochoric and parthenogenetic Bacillus species. I found a R2 degenerate element present in the B. rossius genome since 5 Myr ago. In addition, my analyses for the first time suggest that also R2 retrotransposons can use horizontal transfer as a strategy to colonize a new genome. My data showed a TEs overview in a T. cancriformis parthenogenetic population. In contrast with the theoretical, my analyses highlighted that the 20% of the library is composed by TEs, in which both TEs classes are widely represented (class I, 11.4% and class II, 8.9%).

Texte intégralThe thesis is a contribution to the study of the economic implications of fertility intentions and desires and of the economic aspects of the fertility decision making process. Precisely, it is based on three autonomous chapters and it aims at understanding: a) for women and for individuals within the couples the interplay between fertility and labour market preferences (with a particular focus on the role of women's sector of employment), and the influences that the (un)balanced division of domestic duties play on the intentions of becoming parents for another time in Italy; b) for couples living together the determinants of their (dis)agreement about the intention of becoming parents again; and c) for couples that disagree on future fertility plans, the determinants of female’s contrasting attitude towards her partners’ positive fertility intention. The dissertation uses a mixed-method design- a strategy based on survey data analysis as well as in-depth interviews analysis: this approach allows investigating the topic from different perspectives, by means of both quantitative and qualitative research methods in order to provide new insights into the phenomenon of interest.

Texte intégralThe peripartum period is the most critical stage of the dairy cows. The sudden and major changes in metabolism and life conditions may favor the onset of health problems together with an inflammatory status. An excessive response by the organism to inflammation may subtract primary resources, resulting in a worsening of health status and in a lower milk yield. In the first part of the thesis a new index based on some plasma parameters is proposed to better describe the response to inflammation in the post-calving of dairy cows. An early identification of the animals characterized by a severe response to inflammation, especially without any external symptom, allows an effective intervention in order to avoid further negative consequences. The second and the third part of the thesis describe two experiments aiming to reduce the response to inflammation using ω-3 fatty acids and/or acetylsalicylic acid. The administration of ω-3 fatty acids around calving reduced the inflammatory response and improved the energy balance, while their pre-calving only administration highlighted some slight improvements in inflammatory response and energy balance. The pre-calving administration of acetylsalicylic acid caused the onset of some problems and should be used only after calving.

Texte intégralThis thesis explores the knowledge and practices of the female reproductive body in the process of gynecopoiesis. How do the production, reproduction, transformation and contestation of knowledge about reproduction influence the way women live their bodies? What are the implications of this process on the gender construction and experience? This thesis is based on ethnographic research conducted with thirty women who lived in the city of Bhuj in the state of Gujarat in India. I tried to explore the way in which the different reproductive processes are seen and experienced (ex. menstruation, pregnancy, childbirth, breastfeeding, etc.), paying particular attention to the language and metaphors used to describe them. The research has an approach that integrates a visual and narrative methodology, proposing the technique of body mapping as a tool for analysing body representations. Finally, the research considers how women construct their reproductive health and how reproductive health is reconfigured in the encounter with bio-medicalization of the female body, which is becoming increasingly widespread in the region. The text is organized in three parts. Each part presents with a different angle of analysis: representation, production and care of the female reproductive body. The first part, which is structured around the body maps, focuses on the articulation of anatomical and physiological knowledge. The body is investigated in its materiality and in its somatic manifestations, by the semantic and symbolic articulation of the different bodily substances and fluids. The second part considers the knowledge about the body and different practices that accompany the process of female subjectivation through a project of intentional shaping. The authority of this discourse is set in a model of femininity that transcends the different religious, castal or social groups. This discourse is applied and perpetuated by individual women, through a feminine transmission. In the last section, the body is analysed from the perspective of reproductive health and describes how women conceive and cope with illness. In this context, two of the medical systems most used by women in Bhuj have been taken into consideration: allopathic and local medicine (deśī) represented by the practices of dāī māṃ (traditional birth attendant).

Texte intégralThe thesis is organized into 4 chapters: -in the first chapter, it is briefly overviewed the association of PCV2 with several diseases with particular emphasis to the diagnostic protocols and to the in situ identification of the virus in histological lesions; -in the second chapter, it is presented an original diagnostic protocol to be applied in field conditions, to check for the presence of PCV2 in piglet tissues obtained from stillbirth/abortion. It refers to the application of the protocol in 2 herds and the results are analyzed for a critical review of the used protocol; -in the third chapter, it is presented an experimental trial aimed to infect gilts during artificial insemination by PCV2 infected semen. Conventional gilts were synchronized for oestrus and inseminated with a single dose of semen PCV2 PCR-negative (control group) or experimentally exposed to PCV2 (infected group). The results are analyzed to evaluate the impact that infection in early pregnancy may have on the sow (no pregnancy, return to oestrus), foetuses and foetal membranes. It emphasizes the protective role of circulating antibodies at the time of infection, given the possibility that a low antibody titre is associated with prolonged viremia and increased number of PCV2 positive foetuses; -in the fourth chapter, it is presented a protocol similar to that of Chapter 3, but with the presence of a third group of animals: gilts vaccinated and infected with PCV2 using semen experimentally exposed to the virus. In the discussion 2 important aspects are emphasized: the shedding of the virus is greatly reduced by vaccination, with positive effects on the reduction of the circulation of the virus in the herds; uterine exposure is protected by vaccination, given the low percentage of infected placentas in the vaccinated group compared with not vaccinated and control groups.

Texte intégralFish reproductive ecology, especially reproductive potential, is an essential aspect to understand the population dynamic and for stock assessment purposes. The aim of the PhD thesis deals with the effects of environmental variability on the anchovy reproductive potential. By means of Daily Egg Production Method, were obtained some parameters relative to the reproductive potential. They were analyzed together with environmental parameters (temperature, food availability) during the peak spawning period. Although the data gather information about a thin temporal window, so it was not reasonable to find a wide environmental variability, it shows significant correlations among reproductive parameters, zooplankton density and sea surface temperature. Results could be useful for stock assessment plans, since ecosystem variability has to be included into stock assessment models, according to Ecosystem based approach for sustainable fishery management of the European Common Fishery Policy.

Texte intégralSpecies differences in characters involved in reproductive isolation are candidates for factors that caused speciation. It is not easy to understand whether the species differences that we can detect have been actually involved in speciation, because most species pairs have been accumulating genetic differences since the speciation process was completed often developing multiple reproductive isolating mechanisms. In Hipparchia species and in many taxa of Satyrine butterflies, both sexes have evolved complex genitalia that can mechanically impede the copulation between different species while males have scent located in patches or dispersed on their wings, probably pheromone releaser. Surprisingly, in spite of a growing amount of information on morphology and rearing methods of several species, only the works of Tinbergen on H. semele and some recent research specifically deal with mating behaviour of the genus Hipparchia. Courtship is an important character linked to fitness and can evolve in response to female mate choice, to ensure sex identity and quality of a potential mate. It can also be a major pre-mating isolating mechanism in butterflies and many other species. The aim of this work was to study in detail the reproductive behaviour of two sibling species, Hipparchia fagi and H. alcyone in order to understand which species -specific, visual, behavioural or chemical stimuli are involved in courtship. These two species are sympatric and syntopic at 800 - 1000 m of altitude; adult flight periods overlap in July and August and take place in similar habitats; the two butterflies have very similar wing patterns and sometimes it is very difficult to recognise the species without the exam of male and female genitalia structures. The behavioural study was conducted daily, both in the wild and in captivity, during the reproductive seasons in some areas near Vallemare (1,100 m a.s.l.) in the Central Appennines (Rieti, Italy). The observations were carried out with captive and reared individuals inside a large outdoor “flight cage” built in the same locality and in the garden of the Laboratori di Ecologia Sperimentale ed Acquacoltura (University of Roma Tor Vergata). In this study, different aspects of the butterfly reproductive behaviour are described. First, the ethogram and the sequential structure of courtship are showed; second, various parameters of each courtship step are measured; third, the results in H. fagi are compared with the behaviour of the species H. alcyone; fourth, the mating system of each species is described. Moreover, the male chemical patterns were detected by the application of the Electronic Nose and the results in H. fagi were compared with those of H.alcyone. The study reveals general patterns of sexual behaviour in H. fagi and in H. alcyone, that are mainly identical in both species: perching strategy, flight pursuit and courtship. Likewise, the two species show a similar polygynous mating system, with female monandry. In both species, the results revealed a highly stereotypic courtship that consists of six steps (Fanning, Circling, Bowing, Antenna orientation, Copulation attempt e Clasping) leading to the copulation. Courtship most likely follows up to the end, once the male has started with the sequence. However, the development of the courtship seems to respond to the female behaviour, reflecting the complexity of the male -female interaction during the whole sequence. In both species courtship sequence seems to mostly be the outcome of the female’s reaction: her interruptions can produce fragmented sequences and, more interestingly, can induce the repetition of the sequence around a specific point, with the male persisting in courting the female. Male can mate after displaying the courtship sequence once, but mostly repeats the whole sequence or part of it more than once, restarting from Bowing or previous steps, likely waiting for female signals. The behavioural sequential analysis also showed that a male displays the initial and the final phases of the sequence only once, while he can repeat Bowing and Antenna orientation a lot of times in the same sequence. The comparison between H. fagi and H. alcyone showed quantitative interesting differences. The frequency of Bowing is the unique behavioural character that allows to tell apart the two study species , as H. alcyone shows a greater frequency than H. fagi. In satyrine butterflies, male androconia provide the necessary cue, probably of chemical nature, for a successful courtship, and the display of Bowing is likely of primary importance for the production of male pheromones. During Bowing the male repeatedly bashes or strokes the female’s antennae against the androconial scales on his forewing dorsal surface. Bowing could convey chemotactic information to the female, and its repetition within a sequence could represent a mechanical stimulation for her, with the secretion from androconial patches on the male’s forewings. This phase could be of great importance, as a persistent male could drive a female at first unreceptive to eventually mate. Scents and visual stimuli could have an essential role in mating communication: they could operate synergistically and help the female in her decision of acceptance or rejection of a specific male; they could function as sexspecific signals facilitating sexual identification during courtship. The detection of the butterfly smell by Electronic Nose revealed a similar male chemical pattern in both species. In insects and especially in butterflies, pheromones are chemical signals whose composition varies enormously between species and they typically comprise more than one active component. Frequently sympatric species show the same pheromone components, but in different combinations or ratios. In absence of experimental crossability tests between species, it is not possible to be investigate if different visual (i.e., different performance of a male action) or chemical stimuli would change the female response and impede crossmating. However, the behavioural differences observed in H. fagi and H. alcyone could act as important discordant cues, in case of encounters with heterospecific females, and could reflect the presence of different chemical cues (not yet identified) between the two species.

Texte intégralIl progetto di ricerca si è focalizzato sugli aspetti ecografici ed endocrinologici della fase prepubere e della gravidanza dei piccoli animali. La prima parte del progetto ha valutato alcuni aspetti endocrinologici della gravidanza in cagne di razza Pastore Tedesco, con anamnesi di interestri brevi e riassorbimenti embrionali. I dati degli ormoni presi in considerazione (progesterone e prolattina) sono stati confrontati con quelli rilevati in un gruppo di cagne controllo, con cicli e gravidanze normali. Inoltre, proteina C reattiva e ceruloplasmina, proteine della fase acuta positive, sono state dosate in alcuni dei soggetti appartenenti ai due gruppi per valutare l'esistenza di segni indicativi di cause infiammatorie di riassorbimento embrionale. Durante lo studio sono state trattate, durante la gestazione, con progesterone esogeno, perché sospette di insufficienza luteale. Lo scopo è stato quello di confrontare la concentrazione di progesterone, prolattina, proteina C reattiva e ceruloplasmina in questi due gruppi di cagne, per valutare l'effettiva esistenza della necessità di trattare i Pastori Tedeschi con progesterone esogeno e per approfondire la correlazione esistente tra il progesterone e la prolattina, principale fattore luteotropo durante la seconda parte della gravidanza. E' infatti spesso stato riscontrato durante la mia pratica clinica un utilizzo di supplementazione di progesterone esogeno non giustificato da evidenze cliniche, basato solo su un abbassamento della concentrazione della progesteronemia e che porta l'allevatore a richiedere l'utilizzo di supplementazioni ormonali. Nel secondo lavoro è stato preso in considerazione l'aspetto ecografico della gestazione canina. In particolare il lavoro è stato focalizzato sulla stima della data di parto in cagne di razza Pastore Tedesco utilizzando sia rette di regressione lineare per parametri calcolati da altri autori, sia rette di regressione da noi calcolate specificatamente per il pastore tedesco. La parte 1 del lavoro ha previsto l'applicazione di formule elaborate da altri autori per i parametri ICC (Inner ChorionicCavity) e BP (Biparietal Diameter) per verificare l'accuratezza della stima della data di parto nei soggetti inclusi nel nostro studio. Nella parte 2 del lavoro sono state elaborate rette di regressione lineare per la stima della data di parto in cagne di razza Pastore Tedesco, per i parametri BD (Body Diameter), CRL (Crow Rump Lenght) e DPTV (DeepPortion of TelencephalicVesicle). Nella parte 3 dello studio le formule ottenute nella parte 2 sono state applicate a dati raccolti in cagne gravide di razza Pastore Tedesco con ovulazione non nota. Il terzo lavoro è stato focalizzato sul controllo della riproduzione. E' stato valutato l'effetto dell'impianto di 4.7 mg di Deslorelin nel posporre l'insorgenza della pubertà in gatte prepuberi. Per verificare l'efficacia di questo trattamento sono stati presi in considerazione gli aspetti clinici e comportamentali del della fase estrale quali citologia vaginale e la presenza di cellule cheratinizzate, vocalizzazioni e cifosi. Inoltre sono state valutate le variazioni delle concentrazioni di progesterone ed estrogeni, per valutarne le eventuali alterazioni rispetto ai livelli basali riscontrati durante il periodo prepubere. E' stato infine valutato l'incremento di peso corporeo nelle gatte incluse nello studio.

Texte intégralRecently high fishing pressure has caused a reduction in the biomass of bluefin tuna (Thunnus thynnus L. 1758) populations. The effective management of these fish requires a thorough knowledge of their biology, in particular of their reproduction. The aims of the present project were to improve our understanding on reproductive biology of bluefin tuna (BFT) in captivity, to test innovative methodologies for induction of final gonads maturation (FOM) in caged tunas, and the development of egg collection methods thus establishing the basis for the sustainable development of the BFT aquaculture. Histological and stereological analysis were carried out on 58 samples of BFT kept in captivity from 8 to 54 days (short period), and after 2 years (long period), sacrificed in the fattening cages of Vibo Marina (Italy) during the natural spawning period (June-July 2005-2006). All tunas sampled were adults. When the pooled data from tunas sacrificed in June were compared with those from tunas sampled in July a significant difference in gonadosomatic index (IG) was found (t-test: P=1,6x10-6). The IG decreased almost four-fold from June to July reflecting an evident difference in the degree of sexual maturity. All the female tunas sampled in early June were non-spawning mature and the most advanced group of oocytes found in the ovaries were in nuclear migration stage (S4). At the end of June and at mid July the gonads were classified as in strong regression due to the conversion in atretic oocytes of all the vitellogenic oocytes (S3). At the end of July all bluefin tuna were identified as post-spawning. For the first time, a comparative analysis among anterior, mid and posterior parts of the ovary was carried out. These parts did not greatly differ in the estimated volume fraction of each oocytes category, with the only exception of a lightly higher number of S4 oocytes in the anterior part. When the mean relative batch fecundity, obtained from the numerical density (NV) of S4 oocytes, of 2 years captive tunas was compared with data from about 10 days captive tunas (all sacrificed in the same period on early June) some negative effects of captivity on gonadic maturation was noted. Tunas from about 10 days in captivity, in fact, showed more than five-fold highly yolked oocytes (43.38 ± 17.65 g-1) than 2 years captive ones (8,1 ± 11,5 g– 1). Further, these values were notably lower than those reported by Medina et al. (2002) (93 g-1) for wild northern bluefin tuna. Therefore a long as well as a short period of captivity seemed to altered the final gonadic maturation and reduce fecundity causing reproductive dysfunctions. In order to induce FOM, ovulation/spermiation and spawning a total of 15 BFT were injected underwater with a single dose (20-80 µg Kg-1) of gonadotropin-releasing hormone agonist (GnRHa) encapsulated in microspheres of a biodegradable copolymer. GnRHa implants were administrated without immobilizing or anaesthetizing the fish and using a spare gun and a purpose-built air charged system to insert syringes and a visual tag at the same time. Many attempts were made with different tag, to mark treated tunas, in order to prolong the tag staying on the fish, and to assure that the entire dose will enter in tuna muscle. After each treatment, a special purpose-built net was placed around the cage which demonstrated to be able to retain many fish eggs and larvae. However, no spawning was observed and no tuna eggs were collected from the cage. The absence of spawning in treated tunas could be due to the non-optimal gonadic maturation stage and by the very low plasmatic level of 17-β-estradiol (<1 ng ml-1) of the treated fishes.

Texte intégralInvestigating the reproductive biology and the evolution contributes to define a conceptual model able to explain the processes that allowed any species to succeed. The emergence of innovative anatomical, developmental and physiological features which entail a selective advantage is indeed tightly linked to the success of the reproductive strategy because this favours the species to survive. Furthermore, nowadays, understanding the reproductive strategies is a key for a sustainable use of the biological resources and to respect the principle of intergenerational equity, which consists in the preservation of natural resources and the environment for the benefit of future generations. The overall objectives of the present doctoral dissertation were 1) to investigate the reproductive biology of the swordfish Xiphias gladius and the Atlantic bluefin tuna Thunnus thynnus in the Mediterranean Sea in the context of the fishery management and 2) to shed light onto the evolution of some peculiar anatomical, behavioral and physiological features of the two species. The detailed objectives are provided for each chapter as follows 1) Maturity assignment based on histology-validated macroscopic criteria: tackling the stock decline of the Mediterranean swordfish (Xiphias gladius) • Aims: i) improving the knowledge of the swordfish reproduction in the central and western Mediterranean in terms of histological description of the ovarian stages, reproductive timing and size at first maturity (L50) ii) highlight the importance of the gonadic index (GI) as useful macroscopic indicator through its calibration with the histological approach and the definition of a GI threshold to discriminate sexually immature from mature females 2) A de novo transcriptome assembly approach elucidates the dynamics of ovarian maturation in the swordfish (Xiphias gladius) • Aims: i) elucidating the molecular processes driving the ovarian maturation ii) identifying the main genes of the molecular pathway of steroidogenesis and draw an ad-hoc pathway for the vitellogenin synthesis and uptake integrated with gene expression results iii) characterizing a candidate vitellogenin receptor iv) making the results freely available through a dedicated online portal 3) Some like it hot: the heater tissue transcriptome of the swordfish Xiphias gladius • Aims: i) providing a molecular toolbox to understand the evolution of the regional endothermy in the swordfish ii) expanding the species-specific findings towards the broader exploration of the evolution of endothermy in vertebrates iii) contributing to the knowledge on the heater tissue at a histological level 4) De novo transcriptome assembly, functional annotation and characterization of the Atlantic bluefin tuna (Thunnus thynnus) larval stage • Aims: i) providing the scientific community currently working on the larval rearing with a ready-to-use and annotated transcriptome representative of the larval stage ii) identifying the molecular pathways underlying the high larval growth rates through a comparative approach with other fish species iii) detecting the expanding protein families iv) exploring the biological functions associated with transcripts having higher codon usage bias 5) A comparison of reproductive potential in young and old females: a case study on the Atlantic bluefin tuna in the Mediterranean Sea • Aims: i) Elucidating the reproductive potential of old and young females in the Mediterranean Sea ii) characterizing the expression of mir-202 in young and old females and between reproductive and non-reproductive periods iii) identifying the mir-202 ovarian localization in vitellogenic ovaries

Texte intégralThe qualifying problem of the embryo constitutes the test bed for the civilist in the face of the bursting of innovations in the bio-tech field. While the status of the conceived has been the battleground between the most disparate doctrinal theses and the most recent jurisprudence, the legal status of the extracorporeal embryo is a new but equally controversial issue. The paper moves from a general consideration: there is no unitary discipline to protect the embryo, except for a series of laconic regulatory provisions and penalties, criminal and administrative, contained in the Law February 19, 2004, n. 40, dedicated mainly to assisted fertilization techniques. The legislator in 2004 took the opportunity to regulate, on the one hand and with few rules, the science law of the new millennium and, on the other hand, the asexual procreatic for the overcoming of infertility conditions and the satisfaction of the parental project of many. It follows that the success achieved by reproductive medicine in the last fifteen years has not been accompanied by the use of the legislative instrument capable of grasping the figure of scientific advancement and constitutes handheld proof of it the "exhausting dialectic" of which the legislation on the subject is addressed. The "law 40" has never obtained a resolute legislative intervention to regulate heterologous fertilization, pre-implantation genetic diagnosis and the condition of cryopreserved and supernumerary produced embryos. Institutes, these, passed through the Italian legal system only as a result of the numerous demolition interventions of the Constitutional Court. So the law protects, by means of prohibitions, sometimes declared unconstitutional, an entity, such as the extrauterine embryo, of which the legislator has no clear contours, nor the legal nature. And therefore, even in the absence of a clear framework, if in the past a special statute could have been avoided by the interpreter at the embryo through the lens of these prohibitions, it is necessary to ask what is its status as a result of a careful, systematic and current interpretation. The paper, then, proposes a legal framework of the embryo and a reconstruction of the applicable discipline, the result of a detailed examination of the stratified regulatory framework dedicated to medically assisted procreation and, more generally, the transfer and use of human tissues and cells in the Italian and supranational Biolaw. With regard to the embryo, the subject of this examination, different interpretative approaches have been analyzed, able to guide the jurist in the selection of the applicable rules. These theories are divided according to the method: the first in the groove of the method of adaptation, the last, advocated in this paper, according to the method of innovation. Among the first are the theories of the embryo as conceived, as a subject of law, as a child, and the theories of the embryo as a thing in the legal sense and as part of the body. However, the adaptation of the above mentioned dogmatic categories has not provided satisfactory results, since it is a gimmick incapable of dealing with the most complex issues that have emerged in the treatment of the entity in question. Then, following the teachings of authoritative interpreters of civil law, the most difficult path is taken, namely the application of the method of innovation. For this we proceed to the elaboration of the procedural theory, by virtue of which a unitary framework must be challenged and, instead, the evolutionary process that characterizes the "nascent life" must be taken into consideration. So for each phase and context the jurist identifies a differentiated treatment according to the time segment of reference.

Texte intégralLa diagnosi prenatale sta subendo una rapida evoluzione a causa dell’introduzione sempre più diffusa nella pratica clinica dei test genetici prenatali non invasivi su DNA fetale libero nel sangue materno periferico (NIPT). Ciò è dovuto al fatto che il NIPT è un test di semplice esecuzione, che può essere eseguito in un periodo molto precoce dell’età gestazionale e che permette di evitare il, seppur minimo, rischio di aborto insito nelle tecniche invasive. Inoltre, è risultato avere una maggiore sensibilità e specificità rispetto ai test prenatali attualmente in uso, ed è suscettibile di molte applicazioni. Un’analisi del dibattito in corso mette però in evidenza che esso solleva diversi interrogativi di carattere etico. Si segnalano, in particolare, quelli relativi all’autonomia riproduttiva, alla proporzionalità e alla giustizia distributiva. Nel presente lavoro tali interrogativi vengono analizzati alla luce di una particolare categoria antropologica, la genitorialità. L’ampliamento delle applicazioni tecnologiche nel contesto della vita nascente sfida questa categoria nelle sue componenti costitutive: responsabilità e amore incondizionato. Obiettivo della tesi è di arrivare a proporre dei criteri etico-normativi per la valutazione delle scelte nell’ambito della diagnosi prenatale nell’orizzonte di senso tracciato da queste due componenti.

Texte intégralThis research was carried out from 2009 to 2011 in the Lake of Angitola on the reproductive biology of the slider turtle Trachemys scripta elegans, an alien species that in this site has been naturalized since the 1980’s. According to the International Union for Conservation of Nature (IUCN), invasive species are one of the most important causes of biodiversity decline on a global scale. As a consequence, the impact of introduced species on local ecosystems is important to evaluate. Pet voluntary introductions are done by private people and usually concern only the release of a few individuals. However, the number of releases is as numerous as the number of pet owners that don't want to keep their pet anymore and consequently decide to "release" it. Although only a small percentage of these alien species will become invasive, the environmental impact would be insidious and often irreversible. In fact on a global scale alien species may be as damaging to native species and ecosystems as the loss and degradation of habitats. We can describe 3 steps in the biological invasions processes, comprising the initial dispersal, when an organism moves long distances to areas outside its native range, for example through human assisted dispersal; establishment of self-sustaining populations within the non-native range; and invasion of the new range. However, when species are invasive, they have strongly positive demographic trends and are often numerous, therefore their management can be extremely difficult and expensive. Our experimental model was Trachemys scripta elegans, the most popular freshwater turtle in the pet trade in the world. It is a medium to large-sized turtle as females reach a carapace length of up to 24 cm and males up to 20 cm. This reptile lives in a wide variety of freshwater habitats and it is a habitat generalist. It prefers larg pools and ponds with soft bottoms, and with many aquatic plants and suitable basking sites for thermoregulation. Trachemys scripta elegans is an opportunistic omnivore subsisting on a wide variety of plant and animal foods. The food preferences change with age. Juveniles are highly carnivorous. Instead the adults, mainly eat vegetable food. In the late 1970s a several turtle farms were established in southern USA, where the hatchlings are packed, in hundreds in small boxes, and are shipped abroad. At least 80% of them die during the first year in captivity. If released terrapins survive in nature, they pose a threat to local wildlife. Only in 1996 the total exports of Trachemys scripta elegans from USA were 8 million individuals, of which 3 million individuals were imported by Europe. With effect from 1997 the EU implemented a ban on the import of this species, in fact already in 1975 the U.S. Food and Drug Administration banned the sale of turtles under 10 cm carapace length in the United States and Canada because they transmitted human salmonellosis. Trachemys scripta elegans distribution includes eastern USA, in particular the Mississipi valley from Illinois to the Gulf of Mexico. It now has a far greater distribution area that include a lot of countries in America, Europe and Asia, where it has naturalized in some cases. Trachemys scripta elegans released in seminatural conditions were first recorded in Campobasso in the early 1970s, but sightings only becoming more common in the mid-80s. It is presently known in all of Italy except for Valle d’Aosta, Sardinia and Campania. Reproduction is common in captivity, but little is known about its reproduction in nature. Some authors suggest that naturalization wouldn’t be a serious problem, but it is known that this species is certainly able to reproduce in Friuli Venezia Giulia, Latium, Emilia Romagna and in Calabria. This research was aimed to investigate reproductive biology of Trachemys scripta elegans in order: • to evaluate if reproduction is an effective phenomenon that could interest the study area; • to estimate the reproductive success in natural condition; • to determine preferences of Trachemys scripta elegans in the nest site selection; • to define the step of the invasion process of slider turtle in the Lake of Angitola, in order to suggest conservation measures. The research was conducted at Lake of Angitola, a 196 ha artificial lake located about 5 km from Pizzo Calabro. The lake became a WWF oasis in 1975, and ten years later was declared an International Ramsar area due to the large presence of migratory birds. Today the lake is included in the Regional Park of Serre and in 2005 the area was proposed as a Site of Community Importance (SIC) by ministerial decree. The climate is typically Mediterranean; the vegetation is very varied: the shrub layer is formed by aromatic herbs; the arboreal layer includes a forests of genus Quercus . The animal communities are very interesting, especially the bird population; in fact we can see more than 150 different species per year. The study was conducted from three years, and included 3 monitors per month, in particular from April to October, when the turtles were more active. The lake’s shores were divided into eight transects using environmental criteria. Data collection were sampling focused on visual census observations, on the nesting sites research and on trapping. Also to analyze the nest site selection we divided the whole lake perimeter by differing vegetative covers and differing soil types to study the use of these selected environments by nesting females. Vegetative cover was classified by five categories by a buffer of 50 m, and including shrub land, grass, fruit growing and reforestation; mixed category was used in cases where no one coverage was present in more than 75% of the subdivisions. Soil type was classified by using the methodology of Casanova (1991), yielding three main categories of dirt, sand and clay substrates and the possible combination of them. Collected variables used in this research were tested with InStat 3.0 software; in particular we used Chi-square goodness of fit, Kruskal-Wallis and Spearman Rank Correlation tests. The results of the visual census showed that Cavalcavia was the preferred basking area for Trachemys thermoregulation. In fact, in this area was observed the highest percentage of turtle presence that performed basking on the emerged deadwood. The heterogeneity χ² test, that was used to compare number of observation and the areas, was statistically significant (N=2015; χ²=893,03; d.f.=5; P‹0,0001). Monthly monitoring activities of basking showed an increasing of turtle presence from April to July, and it is possible to observe a subsequent decreasing of basking activities from August to October. During the research we found 229 nests. The greatest distance of a nest from the shoreline was 100 m, but the greatest number of nests was found between 0 and 20 m from the shoreline. Kruskal-Wallis non-parametric test association between number of eggs and months of the year was statistically significant (KW=14,318; P=0,0137). “Movrella” and “Ceramida” were the main nesting areas; in these transects there are a lot of emerged spaces that female turtles can use for nesting activities. The correlation between the number of eggs and the depth of the nest was statistically extremely significant (N=229; r=0,2105; P<0,0001). More than 85% of nests were found in mixed soil type habitats, particurarly in dirt-sand and dirt-clay soil types. Chi squared test between number of nests and soil type categories was statistically significant (N=229; χ²=116,22; d.f.=3; P<0,0001). More than 65% of nests were found in environments with mixed vegetative cover (Grass+Shrubland). Chi squared test associations between number of nests and the 4 vegetative cover types were statistically significant (N=229; χ²=116,22; d.f.=3; P‹0,0001). We collected by trapping, and marked 26 specimens and in particular 6 juveniles; the more effective trapping method was represented by “basking trap”, that we used on the water surface. In Europe reproduction under natural conditions has been reported only for Spain and France. As we said before, little is known about Trachemys scripta elegans reproduction out of captivity in Italy, but in 2002 Ficetola recorded the first reproduction case of Trachemys scripta elegans on the Po Delta on sympatric condition with an Emys orbicularis population. The population of Angitola represents one of the largest reproductive population of Europe and the most important for our country. In Italy Trachemys scripta elegans deposition in seminatural conditions takes place once a year at the end of June. We recorded for the first time that in our study area deposition takes place twice a year, as reported for the American populations: we think that the first event in April-May, with hatching in June and July, and the second event in July- August, with hatching in September-October. Some tropical Trachemys species tend to nest in open areas that receive direct sunlight for at least part of each day. Analysis of the use of vegetative cover in our study area revealed that Trachemys scripta elegans nests were not randomly distributed within the general area used for nesting, and it suggesting that females were actively selecting nesting sites. In fact the largest number of nests around the lake was found in areas with mixed vegetative cover, as reported for Trachemys callirostris in Colombia. Mixed vegetative cover might reduce thermal stress to the nesting females, as well as lower the detectability of nests to natural predators and human hunters. It has been reported that Trachemys nesting females prefer only dirt soil, but in our study area the largest number of nests in our study area were found in habitat with mixed soil type categories, these zones were characterized by heterogeneous granulometry that increase the ventilation of the nest and the humidity degree for hatching success. We investigated experimentally the occupation of basking sites thus providing a better knowledge on this behavioral pattern. During thermoregulation turtles of lake Angitola mainly bask along the emergent deadwood. Floating (thermoregulation on the water surface) is showed especially during the summer season. This population performs basking from April to October at different times of the day: for example during the cooler months the time of sunlight exposure increases and the basking behavior occurs during the hottest hours of the day. These results are also important for further evaluations on competition for occupation of basking places between this allocthonous specie and Emys orbicularis, our endangered European pond turtle. In fact as reported in literature that Trachemys scripta elegans requires less exposure time for thermoregulation than Emys orbicularis, and for this reason American slider turtle is the winning species in competition for basking sites in sympatric conditions. The invasion process of the Trachemys population inhabiting the lake of Angitola is at the second step, in fact we are in front of a self-sustaining and growing population. Moreover the local population of Emys orbicularis, historically present in the lake until the early 2000's, nowadays is probably extinct. In conclusion it is very important to complete echo-ethological investigations for better understanding the biology and ecology of this invader, and to provide a monitoring and controlling plans, and to define translocation and eradication plans, but this operations could be extremely difficult and more expansive. The results of this research were objects of a scientific paper and of same participation for congresses. Two more papers are in preparation.
