Alcohol boosts pheromone production in male flies and makes them sexier
2020
The attraction of Drosophila melanogaster towards byproducts of alcoholic fermentation, especially ethanol, has been extensively studied 1–4. However, the adaptive value of this behavior has not been elucidated. Previous studies have suggested anthropomorphic interpretations of D. melanogaster behavior towards alcohols 5,6. Here, we instead assert that there exists a simple yet vital biological rationale for alcohol contact and consumption by these insects. We show that exposure to alcohols, especially methanol, results in an immediate amplification of fatty acid ester pheromone levels, which in turn elevates the probability that a male will successfully compete for a female during courtshi…
Voila, a New Drosophila Courtship Variant that Affects the Nervous System: Behavioral, Neural, and Genetic Characterization
1998
InDrosophila melanogaster, a specificPGAL4transposon induces theVoila1genetic variant and produces multiple phenotypes. HomozygousVoila1/1flies rarely reach adulthood, whereas heterozygousVoila1/+adult males show strong bisexual behavior. Males with a single copy ofVoila1driving the feminizing transgeneUAS-transformershow very reduced sexual activity but no overall effect on their behavior.Voila1is specifically expressed in the nervous system. In the CNS, it is expressed mainly in the mushroom bodies and, to a lesser extent, in the antennal lobes. In the peripheral nervous system, GAL4 expression is almost entirely restricted to the gustatory sensilla. Using chromosomal deficiencies, the be…
Towards a resolution of the lek paradox
2001
Genetic benefits in the shape of 'good genes' have been invoked to explain costly female choice in the absence of direct fitness benefits. Little genetic variance in fitness traits is expected, however, because directional selection tends to drive beneficial alleles to fixation. There seems to be little potential, therefore, for female choice to result in genetic benefits, giving rise to the 'lek paradox'. Nevertheless, evidence shows that genetic variance persists despite directional selection and genetic benefits of female choice are frequently reported. A theoretical solution to the lek paradox has been proposed on the basis of two assumptions: that traits are condition-dependent, and th…
Stan techniczny i wykorzystanie zabudowań po klasztorach skasowanych w guberni wołyńskiej w latach 1832–1853 w świetle raportu wołyńskiego gubernator…
2019
W trakcie XIX-wiecznych kasat klasztorów na obszarze cesarstwa rosyjskiego względy ekonomiczne stanowił istotny, może najważniejszy, ale niejedyny czynnik, uwzględniany przy podejmowaniu decyzji o zniesieniu domu zakonnego. Oficjalnie władze rosyjskie głosiły, że cały majątek klasztorny miał być wykorzystany na utrzymanie szkół oraz instytucji opiekuńczych i charytatywnych. W rzeczywistości przejęte ziemskie dobra klasztorne zasiliły skarb publiczny, a mienie z różnych powodów niezbywalne powiększyło majątek, pozostający w dyspozycji władz gubernialnych oraz Cerkwi prawosławnej. Władze długo nie doceniały znaczenia zabudowań poklasztornych. Dla większości z nich nie znaleziono nowego użytko…
Family law, religious marriage and sharia courts in western societies.
2019
The chapter analyses the way in which religious marriages and sharia courts interface with State's legal orders in some European countries, focusing on limping marriages and split of status, which derive by the existence of different and pall legal orders: the major, based on the principle of territoriality of the law, and the minor, organized on the personality of the law.
International Courts and the Crime of Genocide
2013
En este trabajo realizo un análisis jurídico de los elementos constitutivos (tanto subjetivos como objetivos) del crimen de genocidio, tal y como han sido interpretados y aplicados por la jurisprudencia internacional. En concreto, se estudia la jurisprudencia de la Corte Internacional de Justicia, del Tribunal Internacional Penal para la antigua Yugoslavia y del Tribunal Internacional Penal para Ruanda sobre el crimen de genocidio.
The role of the agreement as a tool for management of property relations in cases of cross border marriages and civil unions/partnerships registered …
2021
The essay examines the role of the agreement as a tool for managing property relationships in crossborder marriages and registered partnerships, in light of EU Regulations 1103 and 1104 of 2016, on the property regimes of international married or registered couples. The main prerogative of such acts is the recognition of the parties? freedom to choose the court and the applicable law. The law governing the matrimonial property regimes, or the property consequences of registered partnerships, has universal scope. This agreement in the form envisaged, which is backed by the need for legal certainty and predictability of the applicable rules, means that the spouses, in family problems which ha…
Le sollecitazioni delle Corti e l’inerzia del legislatore in tema di suicidio assistito. Un confronto tra Italia e Inghilterra
2019
Starting from the analysis of the decision of the Italian Constitutional Court on the ���Cappato case���, the essay is the occasion for a joint reflection between Italian constitutional law and comparative law on the subject of assisted suicide and euthanasia, which seems to determine the inertia of the legislators in the face of activism of the Courts, perpetually seeking a dialogue with the first. To suffer the most serious damage of these attitudes are the sick, who in this matter more than ever need certainty to the law.
Contact with attractive women affects the release of cortisol in men
2010
Previous studies have shown that situations relevant for human mating can affect the levels of many hormones. This study focused on the hypothalamus-pituitary-adrenal axis by measuring salivary cortisol levels in 84 young men prior to and after a period of short social contact with a woman or man. Results showed that after contact with another man the cortisol levels of the participants declined according to the circadian release pattern of cortisol. However, cortisol levels in men declined less when they had contact with a woman. Furthermore, cortisol levels of men increased when they perceived the woman with whom they had contact as attractive. Our findings provide indirect evidence for t…
Quantitative Genetics of the Aging of Reproductive Traits in the Houbara Bustard
2015
International audience; Do all traits within an organism age for the same reason? Evolutionary theories of aging share a common assumption: the strength of natural selection declines with age. A corollary is that additive genetic variance should increase with age. However, not all senescent traits display such increases suggesting that other mechanisms may be at play. Using longitudinal data collected from more than 5400 houbara bustards (Chlamydotis undulata) with an exhaustive recorded pedigree, we investigated the genetics of aging in one female reproductive trait (egg production) and three male reproductive traits (courtship display rate, ejaculate size and sperm viability), that displa…
