Exploring the mechanisms underlying the last male precedence in the North African houbara bustard Open
The last male precedence (LMP) effect refers to the competitive advantage of the last male in the mating sequence. We conducted in vitro and in vivo experiments to explore the mechanisms underlying LMP in the North African houbara bustard …
Evaluating the impact of reinforcement efforts on imperiled species: The North African houbara bustard Open
Population reinforcement can be an effective strategy for stabilizing declining populations. However, assessing reinforcement success requires comprehensive information on the demography of both wild-born and released individuals. Here, we…
Genome wide data recover hierarchical genetic structure and help define conservation units for the threatened Asian Houbara Open
The Asian Houbara Bustard (Chlamydotis macqueenii), a partially migratory bird from the western and Central Asian steppes, is listed as vulnerable on the IUCN Red List. This study reassesses the species’ genetic structure using modern geno…
HuBot: A biomimicking mobile robot for non-disruptive bird behavior study Open
The Houbara bustard, an avian species of conservation concern, poses significant challenges to researchers because of its elusive nature and sensitivity to human disturbances. Traditional research methods, often reliant on human observatio…

A tri‐axial acceleration‐based behaviour template for translocated birds: the case of the Asian houbara bustard Open
Understanding the behaviours and time budgets of translocated animals post‐release has the potential to improve rearing and release protocols, and therefore survival rate. Otididae (bustards) inhabit open landscapes across the Middle East …
Innovations pour la protection des cultures de pomme de terre vis-à-vis de maladies et de ravageurs majeurs ou émergents. Open
The project aimed to prevent the introduction and the development of major or (re)emerging pests and diseases on potato crops, thanks to the implementation of detection tools, of risk analysis and development of new control methods. The ma…
Non-systematic surveys reveal increases in areas occupied by endangered and data-deficient Nubian bustard Open
A large proportion of endangered species lack good-quality data for assessing population trends. Obtaining these data is especially challenging in remote arid ecosystems, in part because these desert environments have historically attracte…
Pre-but not post-meiotic senescence affects sperm quality and reproductive success in the North African houbara bustard Open
Age-dependent reduction in reproductive success can arise due to multiple factors including a deterioration of reproductive physiology. Senescing males have been shown to produce ejaculates with poor sperm quality, which impinges on male r…
Assisted Reproduction Techniques to Improve Reproduction in a Non-Model Species: The Case of the Arabian Bustard (Ardeotis arabs) Conservation Breeding Program Open
Artificial reproductive technologies are highly valuable for ex situ conservation. While Arabian bustard populations are declining and extinct in some parts of the range, the International Fund for Houbara Conservation in the United Arab E…
Density-dependence of reproductive success in a Houbara bustard population Open
Although density-dependent processes and their impacts on population dynamics are key issues in ecology and conservation biology, empirical evidence of density-dependence remains scarce for species or populations with low densities, scatte…
Timing of Release Influence Breeding Success of Translocated Captive-Bred Migrant Asian Houbara Bustard Open
In conservation translocation, released animals should have comparable fitness to their wild counterparts to effectively contribute to the species demography. Captive-bred animals frequently exhibit lower fitness performances, which can of…
Individuality in houbara chick calls and its dynamics throughout ontogeny Open
In many taxa, breeding success depends heavily on reliable vocal recognition between parents and offspring. Although the acoustic basis of this recognition has been explored in several species, few studies have examined the evolution of ac…
Enforced monoandry over generations induces a reduction of female investment into reproduction in a promiscuous bird Open
While uncovering the costs and benefits of polyandry has attracted considerable attention, assessing the net effect of sexual selection on population fitness requires the experimental manipulation of female mating over generations, which i…
Patterns of abundance reveal evidence of translocation and climate effects on Houbara bustard population recovery Open
Population reinforcement, through translocations of individuals, aims to restore populations of threatened species. The increase in population size or geographic distribution is often used as positive facts when assessing the recovery of a…

Exposure assessment for avian influenza and Newcastle disease viruses from peridomestic wild birds in a conservation breeding site in the United Arab Emirates Open
Worldwide, wild birds are frequently suspected to be involved in the occurrence of outbreaks of different diseases in captive‐bred birds although proofs are lacking and most of the dedicated studies are insufficiently conclusive to confirm…

Risk assessment of Avian Influenza and Newcastle disease viruses exposure from peridomestic wild birds in a conservation breeding site in the United Arab Emirates Open
Worldwide, wild birds are frequently suspected to be involved in the occurrence of outbreaks in captive-bred birds although proofs are lacking and most of the dedicated studies are insufficiently conclusive to confirm or characterize the r…
Paternal age negatively affects sperm production of the progeny Open
Parental age has profound consequences for offspring’s phenotype. However, whether patrilineal age affects offspring sperm production remains unknown, despite the importance of sperm production for male reproductive success in species faci…
Post-copulatory sexual selection allows females to alleviate the fitness costs incurred when mating with senescing males Open
Male senescence has detrimental effects on reproductive success and offspring fitness. When females mate with multiple males during the same reproductive bout, post-copulatory sexual selection that operates either through sperm competition…
Male vocalizations convey information on kinship and inbreeding in a lekking bird Open
Kinship and inbreeding are two major components involved in sexual selection and mating system evolution. However, the mechanisms underlying recognition and discrimination of genetically related or inbred individuals remain unclear. We inv…
Sperm competition accentuates selection on ejaculate attributes Open
Ejaculate attributes are important factors driving the probability of fertilizing eggs. When females mate with several males, competition between sperm to fertilize eggs should accentuate selection on ejaculate attributes. We tested this h…
Supplementary material from "Sperm competition accentuates selection on ejaculate attributes" Open
Ejaculate attributes are important factors driving the probability of fertilizing eggs. When females mate with several males, competition between sperm to fertilize eggs should accentuate selection on ejaculate attributes. We tested this h…
No evidence for prezygotic postcopulatory avoidance of kin despite high inbreeding depression Open
Offspring resulting from mating among close relatives can suffer from impaired fitness through the expression of recessive alleles with deleterious effects. Postcopulatory sperm selection (a prezygotic mechanism of cryptic female choice) h…
Breeding success and juvenile survival in a reintroduced captive-bred population of Asian houbara bustards in the United Arab Emirates Open
Identifying factors influencing breeding success in endangered species is vital for undertaking appropriate conservation measures. The reintroduced population of the captive-bred Asian houbara bustard Chlamydotis macqueenii in reserves of …
