We studied the genetic structure of a hybrid zone between Red-legged (Alectoris rufa) and Rock (A. graeca) partridges in the southern French Alps using six allozyme loci. Allele frequencies showed sharp clinal variation across the hybrid zone, shifting by 60% over a distance of about 60 km, on average. Single-locus clines were coincident, but only...
There is growing evidence that the Earth's climate is undergoing profound changes that are affecting biodiversity worldwide. This gives rise to the pressing need to develop robust predictions on how species will respond in order to inform conservation strategies and allow managers to adapt mitigation measures accordingly. While predictions have beg...

Rock partridge Alectoris graeca saxatilis populations surveyed in the southern French Alps declined rapidly from 1994, reaching very low levels in 1997 and 1998. This decline could be due to the impact of several climatic events which occurred from 1994 through 1996. To evaluate the likelih...
Capsule: Double-nesting occurs frequently in Rock Partridges Alectoris graeca living in the southern French Alps.
Aims: To investigate reproductive parameters of a Rock Partridge Alectoris graeca population.
Methods: The reproductive behaviour of 62 radio-tagged birds was monitored during the breeding seasons 2012–16, to record breeding phenology,...
Breeding system of Alectoris partridges is of peculiar interest because of the potential occurrence of double-nesting within the same breeding season: double-nesting refers to females laying two successive clutches in two different nests without interruption. When both clutches are laid, the first one is incubated by the male and the second one by...
The aim of the presentation is a comparison of the characteristics of the long-distance movements of 3 Gps-tagged mountain Galliformes (Black grouse, Rock ptarmigan and Rock partridge)in the French Alps. The aim is to analyze, in particular, the role of topography in the routes taken during these trips.
The chapter of this book (available in English and French languages) document the conservation status and management of Rock partridge populations, that are listed in the Annex II/A of the Birds Directive, in the various countries of its European distribution.
Interactions between incubating Rock Partridges Alectoris graeca saxatilis and domestic livestock. Rock Partridge living in pastoral areas in the French Alps may interact with livestocks. Are these interactions at the origin of disturbance responsible of the decrease in breeding success ? This question was investigated in northern PreAlps (France)...
Fact sheet on Rock Partridge population distribution, abundance and change in Europe.
This poster is describing the different kinds of movements carried out by radiotagged rock partridges throughout an annual cycle and the implications of this knowledge for management.
Breeding system of Alectoris partridges is of peculiar interest because of the potential occurrence of double-nesting within the same breeding season: double -nesting refers to females laying two successive clutches in two different nests without interruption. When both clutches are laid, the first one is incubated by the male and the second one by...
The starvation-predation risk trade-off predicts that animals should lose some weight when facing a higher predation risk, but without impairing fasting and survival performances. This factor has led to particular concern for the conservation of the alpine rock partridge, which is known to store low fat reserves, and lives in high altitude areas su...
Radio-tracking of juveniles and genetic studies have previously suggested that mountain ridges may represent barrier to dispersal for the Black grouse. In the present study, we assessed the potential of a more straightforward approach to test the effect of these topological features on Black grouse dispersal. We simply compared correlations between...
Cette fiche présente une synthèse de l'état des connaissances concernant la biologie et les menaces qui pèsent sur les populations de Perdrix bartavelle dans les Alpes françaises et propose des actions de gestion conservatoire.
Alpine rock partridge is a game species with a southern European distribution. It is of special conservation concern by living in high altitude areas subjected to harsh weather conditions, to habitat loss due to abandonment of agricultural practices and also to disturbance due to leisure activities. Listed in the Bird Directive (2009/147/EC), its e...
Deciphering the effects of climatic conditions on population dynamics is of major importance in understanding how organisms are likely to be affected by climate changes. Using data from broad-scale annual censuses between 1990 and 2007, we show that winter and summer North Atlantic Oscillations affect several breeding success indicators of the Blac...
Similarly, in Rock Partridge, body fuels would offer less than 3 days fasting endurance under cold conditions. We also assume that Phase II of fasting would be very short and that nutritionnaly stressed individuals heavily rely on protein breackdown for their energy requirements. This helps to better understand the higher foraging activity of this...
The chapter presents the status of the Rock Partridge in France (geographical distribution, abundance, habitat), the factors responsible for the decline of populations, monitoring methods, and hunting management practices
Prescribed-burning appeared in France in the 1980's in order to mitigate fire risk, which is itself related to rural abandonment and a calling into question of shepherds' collective skills. Another purpose of prescribed-burning is the opening of landscapes to favor grazing management and the maintenance of biodiversity. A survey undertaken in the M...
Après son institutionnalisation pour répondre au risque d’incendie lié à la déprise rurale, le brûlage dirigé est aujourd’hui requalifié comme technique d’ouverture du milieu, pour favoriser les activités pastorales et la biodiversité. Une enquête dans le Mercantour en 2004-2005 met en évidence les spécificités de la pratique dans
chacun des deux d...
The decline of over-hunted red-legged (Alectoris rufa) and rock (A. graeca) partridge populations has been contrasted with massive releases of captive-reared birds, often hybrids with non-indigenous A. chukar. Released interspecific hybrids raise the risks of introgressive hybridisation, and can contribute to further depress the fitness of native p...
The aim of the meeting was to get an overview to the conservation status, causes of decline, current management actions and conservation needs for the mountain galliforms inhabiting the Alps. My presentation focused on the French Alps. It is available in both English and Italian.

Cet article propose une synthèse des connaissances actuelles sur l'origine et la structuration génétique de la zone d'hybridation naturelle entre Perdrix bartavelle et Perdrix rouge, et révèle que des lâchers d'individus exotiques (Perdrix choukar et hybrides d'élevage) pourraient compromettre gravement la diversité d...
The sexual dimorphism in size was investigated in a galliform species with monomorphic plumage, the Rock Partridge (Alectoris graeca saxatilis), by measuring five morphological variables on 90 males and 90 females collected in the southern French Alps during autumn hunting seasons 1985 to 1995.
Alpine species may be losing habitat because of global warming. Setting management priorities for such species is thus urgent and cannot be achieved without data on population structure. We studied the structure of rock ptarmigan (Lagopus mutus) populations in the Pyrenees, Alps and Norway, using six microsatellites. We found that rock ptarmigan in...

Questions
Question (1)
I cannot remove the false date "January 2024" indicated under the titles of several old articles and posters that I have entered on 27 and 28 January 2024. I did not imagine that the month and year of entry (January 2024) would be displayed under the title of the publication. Could you please indicate me how to replace this wrong date (January 2024) by the right date of the publication ? Do I have to remove all the articles and posters entered on 27 and 28 January and to enter them again by taking precaution of erasing January 2024 ?
Thank you by advance or your answer.
