Data for: Beyond simple habituation: Anthropogenic habitats influence the escape behavior of spur-winged lapwings in response to both human and non-human threats
<p>Habitat development may affect wildlife behavior, favoring individuals or behaviors that cope better with perceived threats (predators). Bolder behaviors in human-dominated habitats (HDH; e.g., urban and rural settlements) may represent habituation specifically to humans, or a general reduction in predator-avoidance response. However, such carry-over effects across threat types (i.e., beyond humans) and phases of the escape sequence have not been well studied to date. Here we investigated escape behaviors of a locally common wader species, the spur-winged lapwing (Vanellus spinosus). We assayed their flight initiation distance (FID) and subsequent escape behaviors in agricultural areas and in HDH. We found that lapwings in HDH were bolder, and that the difference was manifested in several phases of the predator-avoidance sequence (shorter FIDs, shorter distances fled, and a higher probability of escape by running vs. flying). When re-approached (by an observer) after landing, lapwings in HDH were also more repetitive in their FID than those in other habitats. To determine whether this apparent bolder behavior in HDH areas is merely a consequence of habituation to humans or represents a broader behavioral change, we introduced an additional threat type – a remotely-operated taxidermic jackal ("Jack-Truck"). Finding bolder responses in the HDH to the human threat alone (and not to the Jack-Truck) could have supported the habituation hypothesis. In contrast, however, we found a bolder response in the HDH to both threat types, as well as a correlation between their FIDs across different sites. These bolder behaviors suggest that HDH impose a broader behavioral change on lapwings, rather than just simple habituation. Overall, our findings demonstrate how FID trials can reveal strong behavioral carry-over effects of HDH following human and non-human threats, including effects on the subsequent phases of escaping the predator. Further, FID assays may reveal consistent behavioral types when assessed under field conditions, and offer a direct way to differentiate among the various poorly understood and non-mutually exclusive mechanisms that lead to behavioral differences among organisms in HDH. The mechanistic perspective is essential for understanding how rapid urbanization impacts wildlife behavior, populations, and the range of behaviors within them, even in species apparently resilient to such environmental changes.</p>

Data from: Evaluating anthropogenic threats to endangered killer whales to inform effective recovery plans
Understanding cumulative effects of multiple threats is key to guiding effective management to conserve endangered species. The critically endangered, Southern Resident killer whale population of the northeastern Pacific Ocean provides a data-rich case to explore anthropogenic threats on population viability. Primary threats include: limitation of preferred prey, Chinook salmon; anthropogenic noise and disturbance, which reduce foraging efficiency; and high levels of stored contaminants, including PCBs. We constructed a population viability analysis to explore possible demographic trajectories and the relative importance of anthropogenic stressors. The population is fragile, with no growth projected under current conditions, and decline expected if new or increased threats are imposed. Improvements in fecundity and calf survival are needed to reach a conservation objective of 2.3% annual population growth. Prey limitation is the most important factor affecting population growth. However, to meet recovery targets through prey management alone, Chinook abundance would have to be sustained near the highest levels since the 1970s. The most optimistic mitigation of noise and contaminants would make the difference between a declining and increasing population, but would be insufficient to reach recovery targets. Reducing acoustic disturbance by 50% combined with increasing Chinook by 15% would allow the population to reach 2.3% growth.
