Tengmalm’s Owl has been studied for over 30 years within an area of 150km2 in the Jura Mountains in the northern part of the Canton of Vaud (CH) and in the Department of Doubs (F). From 1985 to 2015, 639 nests were found: 179 in Black Woodpeckers Dryocopus martius cavities and 460 in artificial nestboxes. Each year the number of nests varied from 2 (minimum in 2013) to 57 (maximum in 1992) with an average of 20 nests. Overall and on the long-term, there has been a noticeable reduction in the presence of breeding Tengmalm’s Owl. The average number of nests calculated on a period of 5 years has declined from 19 in 1985-89 to 11.2 in 2010-14. Recaptures and controls of locally ringed birds highlight a considerable nomadism which fluctuates through time. Most adult females and young birds leave the area after “goodyears”, i.e. years with relatively high population densities. Philopatry is highest between the peaks of prey abundance and seems to be male-biased. However, a very low number of them are captured and ringed compared to females. Pine Marten Martes martes is the most important predator of this owl species and can destroy up to two thirds of the nests in specific years. In order to decrease this predation pressure, several mechanical protection systems were tested. These systems give good performances during the first years, but become thereafter less effective and their weakness spreads quickly. Other studies clearly highlighted that predation increases with nestboxes age. The important fluctuations through time of appearance or disappearance of Tengmalm’s Owl in some regions are an adaptation to environmental fluctuation of food conditions and to high vulnerability to Pine Marten predation. Cohabitation of these two predators in mountain forests must have caused adaptation in Tengmalm’s Owl in order to minimize these risks. Among these adaptations, selecting a new nest site rather than an old one seems obvious. A new cavity has less risks to be known and regularly visited by Pine Marten. In order to test this assumption, we moved and reinstalled part of our nestboxes in autumn 2014 and 2015. The first results from 2015 and 2016 seasons are in agreement with this prediction. Nestboxes installed recently or shifted in the previous autumn have a higher occupancy rate (35.5%, N = 42) than those left in place (10.5%, N = 105). Displacement of nestboxes in favourable sectors could be an effective measure to support Tengmalm’s Owl populations. It would stimulate colonization by philopatric males and decrease the risk of predation on breeding nests.
The aim of this study is the analysis of the different treatment of a well-known classical topic in the tradition of the Roman erotic poetry -the poem to the death of a pet-bird-, from the Classical Literature to the Renaissance.

L’étude de la décomposition des carcasses de vertébrés est généralement réalisée lorsque les insectes nécrophages sont actifs ; au printemps, en été et en automne. Mais que se passe-t-il si un animal meurt quelques jours avant l’arrivée des températures froides et de la neige ? Pour répondre à cette question de façon préliminaire, une carcasse de porcelet (30 kg) a été installée dans un boisé de feuillus de novembre 2012 à mai 2013. Pour documenter le processus de décomposition, la carcasse a été photographiée et les insectes échantillonnés à intervalles réguliers. Les résultats démontrent que les températures froides ont perturbé les étapes de décomposition normalement observées (corps frais, gonflé, putréfié, post-putréfié et sec/restes) lors des saisons plus chaudes. En outre, en raison de fluctuations climatiques, seules deux (corps frais/congelé et corps putréfié) des trois premières étapes ont été observées. Les stades post-putréfié et sec n’ont pas été documentés puisque l’ex...

[The mammalian oviduct revisited]The oviducts, or uterine tubes, support the transport and final maturation of gametes, and harbour fertilization and early embryo development. The oviduct environment is finely regulated by ovarian steroids as well as by gametes and embryos that interact with it. Previously regarded as a simple transit zone, the oviduct is now regarded as a complex organ with multiple functions in these various processes. The tubal fluid, now better characterized, is to be regarded as the first interface between the mother and the embryo. It may play a major role in the quality of the conceptus.
