Degradation of sexual reproduction in Veronica filiformis after introduction to Europe

2011

Abstract Background Baker’s law predicts that self-incompatible plant species are generally poor colonizers because their mating system requires a high diversity of genetically differentiated individuals and thus self-compatibility should develop after long-distance dispersal. However, cases like the introduction of the self-incompatible Veronica filiformis (Plantaginaceae) to Europe constitute an often overlooked alternative to this rule. This species was introduced from subalpine areas of the Pontic-Caucasian Mountains and colonized many parts of Central and Western Europe in the last century, apparently without producing seeds. To investigate the consequences of the absence of sexual rep…

Le professioni di agente sportivo e avvocato: reviviscenza dei profili di incompatibilità

2019

This article addresses the issue of the incompatibility between the activity of sports agent and that of lawyer in the light of the new regulation on the sports agent introduced by art. 1, par. 373, of the statute 205/2017. This question appeared, if not completely resolved, at least attenuated following the opinion expressed by the National Bar Council (17 July 2015) according to which, in the absence of a legislative regulation referring the activity of sports agent to a specific profession, the exercise of this activity by the lawyer should be authorized without the need of registration in the relevant register kept by the FIGC. The above mentioned question is re-proposed today to the at…

Étude de la biologie d'une messicole en régression: le bleuet (Centaurea cyanus L.)

2011

Agroecosystems are currently experiencing high biodiversity loss, in particular among the plant species specifically adapted to this habitat. This decline results from cropping systems that have been intensified in Western Europe since the 1950s. The cornflower (Centaurea cyanus L.), considered as emblem of the flora associated with traditional cereals, appears as a species that may be at risk and should be monitored. Indeed, cornflower can serve as a host to predators of crop pests and is strongly attractive for the pollinators. This study examines the biological factors that could potentially cause the decline of this species: spatial distribution, potential for growth, population's genet…

Cytoplasmic incompatibility between Old and New World populations of a tramp ant

2020

Reproductive manipulation by endosymbiotic Wolbachia can cause unequal inheritance, allowing the manipulator to spread and potentially impacting evolutionary dynamics in infected hosts. Tramp and invasive species are excellent models to study the dynamics of host-Wolbachia associations because introduced populations often diverge in their microbiomes after colonizing new habitats, resulting in infection polymorphisms between native and introduced populations. Ants are the most abundant group of insects on earth, and numerous ant species are classified as highly invasive. However, little is known about the role of Wolbachia in these ecologically dominant insects. Here, we provide the first d…

Obstetric significance of anti-Jr(a) antibody.

2001

Abstract The first case in the English-language medical literature of anti-Jr a antibody during pregnancy in a Spanish woman is described. The few reported cases to date about this issue are reviewed, with advice as to an obstetric guideline to follow for pregnant women with this antibody. (Am J Obstet Gynecol 2001;184:75-6.)

Preliminary identification of self-incompatibility genotypes of Sicilian almond landraces

2018

Sicily is the main almond producer in Italy. The almond tree is one of the main protagonists of the Sicilian agrarian landscape, especially in the winter, when the bare branches are covered by white or pinkish flowers. Its presence is particularly significant in the province of Agrigento, in Syracuse and in Ragusa areas, where the almond nut is used for fresh consumption and for the preparation of typical sweets. The extremely rich Sicilian almond germplasm can be useful for genetic improvement, since many local landraces possess aromatic characteristics of the nuts of high value. Self-incompatibility in this species is gametophytic and controlled by a multi-allelic S locus, coding for the …

Is the European Commission a hothouse for supranationalism? : theorising and exploring the world of Commission civil servants

2005

Does the European Commission (Commission) manage to transform and re-direct the roles played by Commission civil servants? To test the old neo-functionalist claim on loyalty transfer among civil servants, this article provides fresh survey and interview data on seconded national experts in the Commission. The transformative powers of the Commission are tested by assessing the extent to which seconded national experts adopt supranational role perceptions. Theoretically, the emergence of supranational role perceptions is accounted for by considering (i) processes of pre-socialisation outside the Commission, (ii) processes of resocialisation inside the Commission, and (iii) organisational inco…

Development of cytoplasmically incompatible and integrated (translocated incompatible) strains ofCulex pipiens fatigans for use in genetic control

1976

Crosses were made between strains of the Culex pipiens complex to select and develop strains with suitable cytoplasmic incompatibility properties for use in field experiments in genetic control of Culex pipiens fatigans near Delhi, India.

First clinical uterus transplantation trial: a six-month report.

2014

Objective To report the 6-month results of the first clinical uterus transplantation (UTx) trial. This type of transplantation may become a treatment of absolute uterine-factor infertility (AUFI). Design Prospective observational study. Setting University hospital. Patient(s) Nine AUFI women and their live uterine donors, the majority being mothers. Intervention(s) Live-donor UTx and low-dose induction immunosuppression. Main Outcome Measure(s) Data from preoperative investigations, surgery and follow-up for 6 months. Result(s) Durations of donor and recipient surgery ranged from 10 to 13 hours and from 4 to 6 hours, respectively. No immediate perioperative complications occurred in any of …
