“…Certain owls are among the predators that have adapted to and colonized suburban and urban environments (Gehlbach 2012, Clément et al 2021, Rodríguez et al 2021. However, large species, such as the Tawny Owl (Strix aluco), may be limited by the size of urban woodland patches (Fröhlich and Ciach 2017).…”

Understanding birds' evolving responses to urbanization is an essential aspect of contemporary biology, and knowledge of the responses of nocturnal species lags behind that of diurnal species. In this issue of Western Birds, Jonah Gula addresses the occurrence of the Western Screech-Owl in a mosaic of oak woodland, chaparral, and residential development in the foothills of San Diego County, California. He found the owl more reliably in larger patches of woodland and in patches adjacent to undeveloped chaparral. But the distance to and size of the next nearest patch of woodland were unrelated to the owl's occurrence, suggesting the birds disperse readily across the habitats separating the woodland patches.

“…Plasticity is complex because it can be either reversible or irreversible and may occur across generations (Pigliucci, 2001; Galloway & Etterson, 2007). Behavioural plasticity may occur in response to changes in the environment with regard to habitat selection, including breeding and foraging habitats, and has been observed across a wide variety of taxa (Clément et al, 2021; Gilbert et al, 2017; Morelli, 2012). Behavioural responses may be conditioned by past experience, whereby a stimulus elicits a fixed response after the first experience (e.g.…”

Adaptive capacity can present challenges for modelling as it encompasses multiple ecological and evolutionary processes such as natural selection, genetic drift, gene flow and phenotypic plasticity. Spatially explicit, individual‐based models provide an outlet for simulating these complex interacting eco‐evolutionary processes. We expanded the existing Cost‐Distance Meta‐POPulation (CDMetaPOP) framework with inducible plasticity modelled as a habitat selection behaviour, using temperature or habitat quality variables, with a genetically based selection threshold conditioned on past individual experience. To demonstrate expected results in the new module, we simulated hypothetical populations and then evaluated model performance in populations of redband trout (Oncorhynchus mykiss gairdneri) across three watersheds where temperatures induce physiological stress in parts of the stream network. We ran simulations using projected warming stream temperature data under four scenarios for alleles that: (1) confer thermal tolerance, (2) bestow plastic habitat selection, (3) give both thermal tolerance and habitat selection preference and (4) do not provide either thermal tolerance or habitat selection. Inclusion of an adaptive allele decreased declines in population sizes, but this impact was greatly reduced in the relatively cool stream networks. As anticipated with the new module, high‐temperature patches remained unoccupied by individuals with the allele operating plastically after exposure to warm temperatures. Using complete habitat avoidance above the stressful temperature threshold, habitat selection reduced the overall population size due to the opportunity cost of avoiding areas with increased, but not guaranteed, mortality. Inclusion of plasticity within CDMetaPOP will provide the potential for genetic or plastic traits and ‘rescue’ to affect eco‐evolutionary dynamics for research questions and conservation applications.
