“…In this case, a stochastic network was characterized as a graph consisting of breeding locations (nodes) connected via immigration (directional edges) and fidelity (self‐loops). Using network analysis can improve our understanding of the characteristics of breeding locations and connectivity of spatially distinct breeding areas at a fine scale, allowing for empirical tests of habitat selection and identifying key areas to conserve (e.g., le Roux & Nocera, 2021). Management actions to improve habitat quality, such as vegetation removal or predator control, could be targeted to specific areas by identifying nodes with high connectivity values from the network graphs (Swift et al, 2023).…”

“…Habitat fragmentation and loss can influence connectivity among habitat patches by changing the spatial structure of the habitat network, such as through the removal of highly connected patches (i.e., hubs; Masier & Bonte, 2020). Habitat loss has been implicated in population declines for numerous species (Fahrig, 2001; Johnson, 2007; le Roux & Nocera, 2021), so an improved understanding of how individuals select habitats over both space and time, and differences between individuals immigrating to new areas and those with site fidelity is critical to effectively manage habitats.…”

Conspecific density and habitat quality affect breeding habitat selection: Support for the social attraction hypothesis

Breeding habitat selection is a critical component of the annual cycle because of its effect on fitness. Multiple theories of habitat selection can be differentiated by their responses to the quantity of habitat, conspecific density, and habitat quality. Here, we use network analysis to understand the characteristics of fine‐scale breeding habitat selected by both immigrant and returning adult piping plovers (Charadrius melodus) to test five hypotheses of habitat selection. Between 2014 and 2019, we recorded 2034 uniquely marked adults breeding at 326 breeding locations with 1240 successive breeding events. Among adults, immigration events (i.e., individuals that moved to a new breeding location) were detected as often as fidelity to the same breeding location. We found support for the social attraction hypothesis for both immigrants and returners, indicating that adult plovers use social cues for settlement decisions. Adult plovers selected habitats with intermediate levels of conspecific density and high habitat quality, as assessed by con‐ and heterospecific nest survival, with no effect from the amount of available habitat. We also simulated the loss of breeding habitat and identified highly connected breeding locations, which occurred mostly on the riverine habitat type, which have important implications for habitat conservation for this listed species. Our results highlight the role of conspecifics at identifying high‐quality breeding habitat regardless of whether individuals return to the same breeding site or immigrate to new areas.

“…Understanding sleep behavioural decisions is important to fully comprehend their impact on ecological dynamics, including resource acquisition [15], mating [16] and mechanisms reducing predation risk [17]. Moreover, integrating social network analysis (SNA), which elucidates the spatial structure and implications for behaviour [18,19], allows for a more comprehensive evaluation of the consequences of spatial behaviours on social dynamics and network connectivity [20][21][22].…”

Wildlife demography is influenced by behavioural decisions, with sleep being a crucial avian behaviour. Avian species use roost sites to minimize thermoregulation costs, predation risk and enhance foraging efficiency. Sleep locations are often reused, forming networks within the home range. Our study, focusing on female eastern wild turkeys ( Meleagris gallopavo silvestris ) during the reproductive season, used social network analysis to quantify both roost site selection and network structure. We identified roost networks which were composed of a small percentage of hub roost sites connecting satellite roosts. Hub roosts were characterized by greater values of betweenness ( β = 0.62, s.e. = 0.02), closeness ( β = 0.59, s.e. = 0.03) and eigenvalue centrality ( β = 1.15, s.e. = 0.05), indicating their importance as connectors and proximity to the network’s functional centre. The probability of a roost being a hub increased significantly with greater eigenvalue centrality. Female wild turkeys consistently chose roost sites at lower elevations and with greater topographical ruggedness. Hub roost probability was higher near secondary roads and further from water. Our research highlights well-organized roost site networks around hub roosts, emphasizing the importance of further investigations into how these networks influence conspecific interactions, reproduction and resource utilization in wild turkeys.

Although the global conversion of wildlife habitat to built environments often has negative impacts on biodiversity, some wildlife have the ability to cope by living in human-made structures. However, the determinants of this adaptation on a global scale are not well understood and may signify species with unique conservation needs at the human–wildlife interface. Here, we identify the trait profile associated with anthropogenic roosting in bats globally and characterize the evolution of this phenotype using an original dataset of roosting behavior developed across 1,279 extant species. Trait-based analyses showed that anthropogenic roosting is predictable across bats and is associated with habitat generalism, small geographic ranges, small body size, temperate zone distributions, and insectivory. We identified moderate phylogenetic signal in this complex phenotype, which has undergone both gains and losses across bat evolution and for which speciation rates are lower compared to natural roosting bats.
