“…Yet, these responses changed in their detail with season, highlighting the ecological complexity of BT-dependent space use. In contrast to other examples [23,25,27,57,58], the space-use differences we observed among BTs did not result from confounding factors such as using a movement-based BT definition (e.g. activity or exploration), or from any difference among BTs in the habitat or niche they occupied, or from differences in their social context (e.g.…”

When the going gets tough: behavioural type-dependent space use in the sleepy lizard changes as the season dries

Understanding space use remains a major challenge for animal ecology, with implications for species interactions, disease spread, and conservation. Behavioural type (BT) may shape the space use of individuals within animal populations. Bolder or more aggressive individuals tend to be more exploratory and disperse further. Yet, to date we have limited knowledge on how space use other than dispersal depends on BT. To address this question we studied BT-dependent space-use patterns of sleepy lizards (Tiliqua rugosa) in southern Australia. We combined high-resolution global positioning system (GPS) tracking of 72 free-ranging lizards with repeated behavioural assays, and with a survey of the spatial distributions of their food and refuge resources. Bayesian generalized linear mixed models (GLMM) showed that lizards responded to the spatial distribution of resources at the neighbourhood scale and to the intensity of space use by other conspecifics (showing apparent conspecific avoidance). BT (especially aggressiveness) affected space use by lizards and their response to ecological and social factors, in a seasonally dependent manner. Many of these effects and interactions were stronger later in the season when food became scarce and environmental conditions got tougher. For example, refuge and food availability became more important later in the season and unaggressive lizards were more responsive to these predictors. These findings highlight a commonly overlooked source of heterogeneity in animal space use and improve our mechanistic understanding of processes leading to behaviourally driven disease dynamics and social structure.

“…Although the detection of personality-dependent spatial behaviors is relatively rare, our detection of personality-dependent HR, movement, dispersal, and site fidelity complements personalitydependent spatial ecology noted in other studies and for other taxa, including HR in feral cats Felis catus (Barratt 1997), and starlings Sturnus vulgaris (Minderman et al 2010), migratory movements and site fidelity in roach Rutilus rutilus (Chapman et al 2011;Brodersen et al 2012), and dispersal in invasive mosquitofish G. affinis (Cote et al 2010(Cote et al 2011. Furthermore, our repeatability values are similar to the average values (R = ~0.37) reported for most behaviors in a meta-analysis by Bell et al (2009).…”

“…Nonetheless in both fish and other animal populations, evidence of temporally consistent, cross-contextual patterns of personality-dependent dispersal is rare (Miriam et al 2013). Furthermore, only a few authors have investigated the role of personality in other important spatial ecology metrics including HR (Minderman et al 2010), movement (Fraser et al 2001;Chapman et al 2011;Brodersen et al 2012), and site fidelity (Brodersen et al 2012). Indeed, individual differences in movement behaviors are a typical feature of spatial ecology data sets, particularly in fishes (Conrad et al 2011;Taylor and Cooke 2012), which often feature "resident" and "mobile" contingent strategies (Skalski and Gilliam 2000;Fraser et al 2001;Morrissey and Ferguson 2011;Radinger and Wolter 2013).…”

Personality-dependent spatial ecology occurs independently from dispersal in wild burbot (Lota lota)

Although personality has been documented in numerous animals and characters, research into personality-dependent spatial ecology has focused on dispersal. Indeed, few authors have investigated the role of other important spatial traits such as home range, movement distance, vertical activity, and site fidelity, and it is not clear whether these behaviors are correlated with dispersal. In this study, we investigated individual differences in home range, dispersal from release, vertical activity, movement distance, and site fidelity of 44 wild burbot Lota lota over 2 years, using an acoustic telemetry array and a Bayesian mixed modeling framework. We tested whether the spatial behaviors met the following criteria for personality-dependent behavior: repeatability, cross-contextual consistency, and an absence of pseudo-repeatability associated with spatial context choice. We then tested for between-individual correlations among spatial behaviors, indicative of a behavioral syndrome. Our results documented repeatable, cross-contextually consistent, personalitydependent home range, movement, dispersal from release, and site fidelity. In contrast, behavioral differences in vertical activity were inconsistent across sampling years and may have been a product of habitat heterogeneity. Our data indicate a spatial behavioral syndrome occurred independently from dispersal from release, with behavioral types ranging from "resident" individuals with small home ranges, high site fidelity, and minimal movement to "mobile" individuals with large home ranges, high movement rates, and little site fidelity. Our findings suggest animal personality can play a key role in shaping the space use of individuals, and this diversity in spatial behaviors may be too complex to be captured by often used simple linear measures of dispersal.

“…Previous studies have reported relationships between boldness and activity axes (Boyer et al 2010;Lantová et al 2011;Dammhahn 2012;Herde and Eccard 2013), while others have demonstrated links between those traits and dispersal (Fraser et al 2001;Dingemanse et al 2003) or space use (Boon et al 2007;Minderman et al 2010). Although we did not relate tests to behavior of bears after release, we believe our study provides a framework for future rehabilitation and release programs interested in assessing individual behavior and correlates to post-release behavior and space use.…”

Personality is defined as consistency in individual differences in organismal behavior across time or context, a phenomenon of interest within behavioral and evolutionary ecology. Empirical data have revealed an ever-increasing number and diversity of taxa that display these phenotypic patterns in both wild and captive settings. Moreover, these behavioral traits are frequently linked to wild behavior, life history strategies, and measures of individual fitness. Understanding personality is of particular importance for some animals, such as large carnivores, which may express maladaptive behavior that can lead to conflict with humans. To date, few studies of personality exist on large carnivores and none have investigated the presence of personality in black bears (Ursus americanus). Through focal animal sampling, and open field, novel object, and startle object tests, we investigate the potential for personality in captive black bear cubs. Results indicate the presence of personality, with consistency in behavior across five metrics for the bold-shy axis, and eight sampling events measuring responses for the activity axis. Information presented here reveals the presence of personality in black bear cubs, and may provide a framework for future investigations into relationships of personality with ecology and life history.
