Breeding propensity, i.e., the probability that a mature female attempts to breed in given year, is critical demographic parameter long‐lived species. Life‐history theory predicts this trait should be affected by reproductive trade‐offs so of future reproduction depend on current investment. However, breeding propensity one most difficult parameters estimate because nonbreeders are often absent from area, thereby requiring inclusion unobservable states analysis. We developed new...
Understanding effects of harvest on population dynamics is major interest, especially for declining species. European lapwing Vanellus vanellus populations increased from the 1960s until 1980s and declined strongly thereafter. About 400,000 lapwings are harvested annually it thus high conservation relevance to assess whether hunting was a main cause observed changes in trends. We developed multi-event cause-specific mortality model which we applied long-term ring-recovery data set...
In migrant animals, conditions encountered at various times and places throughout their annual cycle may affect breeding success. Yet, most studies so far have only investigated the effect of specific parts cycle, despite importance to understand how different stages can interact these compare intrinsic quality properly modulate Using a structural equation modelling approach, we drivers success (migration individual quality, conditions) in hoopoes Upupa epops , long‐distant migrant. Our...
The survival of captive‐bred individuals from release into the wild to their first breeding season is crucial assess success reintroduction or translocation programmes, and potential impact populations. However, assessing following often complicated by immediate dispersal once in wild. Here, we apply Lindberg's robust design model, a method that incorporates emigration study site, obtain true estimates Mallards Anas platyrhynchos , common duck species released on large scale Europe since...

Abstract There is growing evidence that the Earth's climate undergoing profound changes are affecting biodiversity worldwide. This gives rise to pressing need develop robust predictions on how species will respond in order inform conservation strategies and allow managers adapt mitigation measures accordingly. While have begun emerge at extremes of so‐called slow‐fast continuum might change, empirical studies for which all demographic traits contribute relatively equally population dynamics...

Abstract Migratory birds have a narrow time window to breed, especially in the Arctic, where early nesting typically yields highest reproductive success. We assessed temporal changes (1991–2015) success components relation timing of breeding greater snow geese ( Chen caerulescens atlantica ). This species breeds Canadian region that has experienced strong warming trend. tested effect laying or hatching date, year and their interaction on six components: Total clutch laid, success, egg...
Abstract Adaptive management of harvested waterfowl requires accurate estimations demographic parameters. These must also be representative the targeted population. In greater snow goose, all parameters so far have been estimated from long‐term banding conducted at a single nesting colony in Arctic, Bylot Island, where 15% population breeds. We used data second program on Ellesmere 800 km north Island and near northern limit breeding range, to compare adult survival between these 2 sites...
In western Europe, common pochard populations have experienced a sharp decline over the last two decades, together with an increasing proportion of males. Both these changes were suggested to result from decreasing survival nesting females (i.e. adult females) owing predation pressure. To test this hypothesis, we used capture–mark–recapture/recovery data ringed during autumn–winter (October–February) in three countries Europe (Switzerland, United Kingdom and France). We found no evidence for...
Assessing trends in the relative abundance of populations is a key yet complex issue for management and conservation. This major aim many large-scale censusing schemes such as International Waterbird Count (IWC). However, owing to lack sampling strategy standardization, likely suffer from biases due spatial heterogeneity effort. Despite huge improvements statistical tools that allow tackling these issues (e.g., GLMM, Bayesian inference), conservationists still prefer rely on stand-alone...
The consequences of releasing captive-bred game animals into the wild have received little attention, despite their potential demographic impact, as well costs and/or benefits for recipient populations. If restocking aims at increasing harvest opportunities, increased hunting pressure is expected, which would then be supported by either or released individuals. On other hand, population may benefit from release conspecifics if this reduces on former through dilution risk selective harvesting...
Understanding demographical processes underlying abundance and population size fluctuations is critical to species management. Knowing key parameters responses observed changes can reduce the number of realistic management scenarios. In hunted species, survival might be targeted parameter for effective plans. The red‐legged partridge Alectoris rufa a native in Mediterranean countries. hunted, especially France where some release plans are implemented. However, estimates scarce there most...
Abstract To document and halt biodiversity loss, monitoring, quantifying trends assessing management conservation strategies on wildlife populations communities are crucial steps. With increasing technological innovations, more data collected new quantitative methods constantly developed. These rapid developments come with an need for analytical skills, which hardly accessible to managers. On the other hand, researchers spend time research grant applications administrative tasks, leaves...
