“…Indirect evidence of the costs of dispersal comes from studies showing that migration is costly (especially for young and inexperienced individuals) compared to individuals that stay at breeding sites 10 – 12 . However, some individuals may also increase or maintain their reproductive performance after dispersal 13 , 14 , although estimating the costs and benefits of dispersal is challenging in ecological studies 15 , 16 .…”

Standard procedures for capture–mark–recapture modelling (CMR) for the study of animal demography include running goodness-of-fit tests on a general starting model. A frequent reason for poor model fit is heterogeneity in local survival among individuals captured for the first time and those already captured or seen on previous occasions. This deviation is technically termed a transience effect. In specific cases, simple, uni-state CMR modeling showing transients may allow researchers to assess the role of these transients on population dynamics. Transient individuals nearly always have a lower local survival probability, which may appear for a number of reasons. In most cases, transients arise due to permanent dispersal, higher mortality, or a combination of both. In the case of higher mortality, transients may be symptomatic of a cost of first reproduction. A few studies working at large spatial scales actually show that transients more often correspond to survival costs of first reproduction rather than to permanent dispersal, bolstering the interpretation of transience as a measure of costs of reproduction, since initial detections are often associated with first breeding attempts. Regardless of their cause, the loss of transients from a local population should lower population growth rate. We review almost 1000 papers using CMR modeling and find that almost 40% of studies fitting the searching criteria (N = 115) detected transients. Nevertheless, few researchers have considered the ecological or evolutionary meaning of the transient phenomenon. Only three studies from the reviewed papers considered transients to be a cost of first reproduction. We also analyze a long-term individual monitoring dataset (1988–2012) on a long-lived bird to quantify transients, and we use a life table response experiment (LTRE) to measure the consequences of transients at a population level. As expected, population growth rate decreased when the environment became harsher while the proportion of transients increased. LTRE analysis showed that population growth can be substantially affected by changes in traits that are variable under environmental stochasticity and deterministic perturbations, such as recruitment, fecundity of experienced individuals, and transient probabilities. This occurred even though sensitivities and elasticities of these parameters were much lower than those for adult survival. The proportion of transients also increased with the strength of density-dependence. These results have implications for ecological and evolutionary studies and may stimulate other researchers to explore the ecological processes behind the occurrence of transients in capture–recapture studies. In population models, the inclusion of a specific state for transients may help to make more reliable predictions for endangered and harvested species.

“…Even though there are a large number of empirical evolutionary studies on survival-reproduction trade-offs in animals e.g. [15][16][17] , and some of them used uni-state CMR e.g. 7,8 , relatively little is known about their potential effects on population dynamics.…”

“…This heterogeneity may result from the species behaviour in relation to breeding site selection and dispersal. Indeed, during the breeding season, kittiwake behaviour may be influenced by individual and conspecific breeding performance (Chambert et al 2012, Ponchon et al 2015a, 2017b, which may itself condition site fidelity the following year (Danchin et al 1998, Naves et al 2006, Boulinier et al 2008, Ponchon et al 2015a, 2017b, Acker et al 2017). If individuals successfully breed within a monitored plot, they will be more likely to remain faithful to their breeding site and thus their probability to be resighted the following year may be higher.…”

“…We also evaluated the benefits of buffer areas on the estimation of annual adult survival. The black‐legged kittiwake is particularly suitable for this analysis because dispersal is often induced after breeding failure due to predation on offspring and it can occur both at local and regional spatial scales (Danchin et al 1998, McCoy et al 2005, Acker et al ). We built three datasets, corresponding to three different spatial scales covered in the survey (Fig.…”

Survival estimates strongly depend on capture–recapture designs in a disturbed environment inducing dispersal

Capture–recapture (CR) approaches are extensively used to estimate demographic parameters. Their robustness relies on the selection of suitable statistical models, but also on the sampling design and effort deployed in the field. In colonial or territorial species showing breeding site fidelity, recurrent local perturbations, such as predation‐induced breeding failure, may lead individuals to disperse locally or regionally. This might induce heterogeneity in individual CR histories and biases in demographic parameter estimates. Here, we assessed the effect of buffer areas and multi‐site designs on annual survival estimate accuracy and precision. First, using simulated data with and without a multi‐site design, we compared survival estimates for different scenarios involving contrasted local and regional dispersal. Then, using data from a local multi‐site long‐term monitoring survey carried out in a colony of black‐legged kittiwakes, we tested the homogeneity of individual CR histories and compared survival estimates from three datasets including one or several breeding cliffs with or without buffer areas. Results from simulations highlighted that a single‐site design consistently led to underestimated or less precise survival values compared to a multi‐site design. Similarly, a multi‐site design allowed detecting significant temporal trends while a single‐site one did not. In the field‐based study, adding buffer areas reduced individual heterogeneity, but all three datasets suffered from strong trap‐dependence possibly due to individual breeding success affecting nest‐site fidelity. Implementing a multi‐site design significantly improved the accuracy and precision of annual survival estimates, regardless of CR models applied. Adapting the spatial scale of sampling design to the local environment and species behaviour is essential to provide robust parameters of key relevance for population monitoring and management. We show that implementing buffer areas and/or multi‐site designs may be especially beneficial for long‐lived species facing regular local perturbation events leading to local dispersal.

“…Moreover, decision‐making based on density could depend on spatial scale. Habitat selection is often a hierarchical process starting at the broader habitat patch scale (discrete options on a landscape characterized by dominant vegetation and structure; Söderström & Part, ; Bowne & Bowers, ; Acker, Besnard, Monnat, & Cam, ), followed by finer within‐patch settlement decisions (such as territory establishment; Holmes, Marra, & Sherry, ; Chalfoun & Martin, ). Songbirds use social cues for habitat selection at both scales (habitat patch: Doligez et al., ; Citta & Lindberg, ; and territory: Ahlering et al., ; Kivelä et al., ).…”

Who is in the neighborhood? Conspecific and heterospecific responses to perceived density for breeding habitat selection

et al. 2018

Theoretical models of habitat selection often incorporate negative density dependence. Despite strong negative density‐dependent effects on habitat selection, more recent studies indicate that animals settle near members of their own (conspecific) and other species (heterospecific) when selecting habitat with social cues. Social cue use for habitat selection is particularly common among songbirds, but few studies have investigated if songbirds use social cues to assess conspecific or heterospecific density (as opposed to just presence/absence) when making settlement decisions. We conducted a playback experiment to evaluate if yellow warblers (Setophaga petechia) and willow flycatchers (Empidonax traillii), two potential competitors for breeding habitat, use social cues to assess density (conspecific for warblers and heterospecific for flycatchers) when selecting breeding locations at two spatial scales. We simulated yellow warbler density to be high or low at multiple treatment plots (3.14 ha) with song playback and then evaluated settlement decisions by comparing yellow warbler and willow flycatcher abundances across plots (broad‐scale habitat selection) and individual space use within plots (fine‐scale territory establishment). Yellow warbler density treatments did not affect habitat selection by yellow warblers at the broad scale, but caused individuals to cluster territories at high‐density treatments. Willow flycatchers were most abundant at high‐density treatment plots, but yellow warbler density treatments did not affect territory locations. The results indicate that perceived density affects the habitat selection process for both conspecifics and heterospecifics.
