A systematic survey of the integration of animal behavior into conservation
The role of behavioral ecology in improving wildlife conservation and management has been the subject of much recent debate. We sought to answer 2 foundational questions about the current use of behavioral knowledge in conservation: To what extent is behavioral knowledge used in wildlife conservation and management, and how does the use of animal behavior differ among conservation fields in both frequency and types of use? We searched the literature for intersections between key fields of animal behavior and conservation and created a systematic heat map (i.e., graphical representation of data where values are represented as colors) to visualize relative efforts. Some behaviors, such as dispersal and foraging, were commonly considered (mean [SE] of 1147.38 [353.11] and 439.44 [108.85] papers per cell, respectively). In contrast, other behaviors, such as learning, social, and antipredatory behaviors were rarely considered (mean [SE] of 33.88 [7.62], 44.81 [10.65], and 22.69 [6.37] papers per cell, respectively). In many cases, awareness of the importance of behavior did not translate into applicable management tools. Our results challenge previous suggestions that there is little association between the fields of behavioral ecology and conservation and reveals tremendous variation in the use of different behaviors in conservation. We recommend that researchers focus on examining underutilized intersections of behavior and conservation themes for which preliminary work shows a potential for improving conservation and management, translating behavioral theory into applicable and testable predictions, and creating systematic reviews to summarize the behavioral evidence within the behavior-conservation intersections for which many studies exist. El papel de la ecología conductual en el mejoramiento de la conservación y el manejo de la fauna ha sido sujeto recientemente a muchas discusiones. Buscamos responder dos preguntas fundamentales acerca del uso actual del conocimiento conductual en la conservación: ¿Hasta qué punto se utiliza el conocimiento conductual en la conservación y manejo de la fauna y cómo difiere el uso del comportamiento animal, tanto en frecuencia como en tipos de uso, entre las áreas de conservación? En la literatura buscamos intersecciones entre áreas clave de la conservación y el comportamiento animal y creamos un mapa sistemático de calor (es decir, una representación gráfica de los datos en la que los valores se representan con colores) para visualizar los esfuerzos relativos. Algunos comportamientos, como la dispersión y el forrajeo, se consideraron como comunes (media [SE] de 114.38 [353.11] y 439.44 [108.85] artículos por celda, respectivamente). En contraste, otros comportamientos como el aprendizaje y las conductas sociales y anti-depredadores se consideraron como raras (media [SE] de 33.88 [7.62], 44.81 [10.65] y 22.69 [6.37] artículos por celda, respectivamente). En muchos casos, la detección de la importancia del comportamiento no se tradujo en una herramienta aplicable de manejo. Nuestros resultados presentan un reto a las sugerencias previas de que existe poca asociación entre las áreas de la ecología conductual y la conservación y revelan una variación tremenda en el uso de diferentes comportamientos dentro de la conservación. Recomendamos que los investigadores se enfoquen en examinar intersecciones sub-utilizadas de temas de comportamiento y conservación para los que el trabajo preliminar muestre un potencial para mejorar la conservación y el manejo; traduzcan la teoría conductual a predicciones aplicables y evaluables; y creen revisiones sistemáticas para resumir la evidencia conductual dentro las intersecciones de comportamiento-conservación para las que existen muchos estudios.
Aversive conditioning increases short-term wariness but does not change habitat use in black bears associated with conflict
Conflict between humans and black bears ( Ursus americanus ) occurs throughout North America with increasing public demand to replace lethal management with non-lethal methods, such as aversive conditioning (AC). AC aims to teach animals to associate negative stimuli with humans or their infrastructure. We sought to test the efficacy of AC using radio-collared black bears in Whistler, British Columbia, by monitoring individuals and assigning those in conflict with people to control or treatment groups. We measured wariness using overt reaction distance, displacement distance, and reaction to researchers before, during and after executing 3–5-day AC programs that consisted of launching projectiles at bears in the treatment group. We also assessed predictors of successful AC events (i.e., leaving at a run), changes in bear use of human-dominated habitat during the day and at night, and the effects of including a sound stimulus to signal the beginning and end of AC events. Among treated bears, overt reaction distance increased by 46.5% and displacement distance increased by 69.0% following AC programs, whereas both overt reaction distance and displacement distance decreased over time among control group bears. Each additional AC event during the previous 30 days increased likelihood of bear departure in response to researcher presence by 4.5%. The success of AC events varied among individuals, declined with distance to cover, and increased with exposure to previous AC events. Projectiles launched from guns were slightly more effective at causing bears to displace compared to those launched from slingshots, and sound stimuli decreased the likelihood of a successful AC event. AC did not alter diurnal use by bears of human-dominated habitat. Our results suggest that AC effectively increases short-term wariness in black bears but does not alter bear use of human-dominated spaces, highlighting the importance of proactive attractant management and prevention of food conditioning.
