Understanding the intricacies of animal behaviour is paramount in effective wildlife conservation. A recent paper titled "Should we consider individual behaviour differences in applied wildlife conservation studies?" by Melissa J. Merrick and John L. Koprowski sheds light on the importance of incorporating individual behavior differences, such as animal personalities and behavioral syndromes, into applied wildlife conservation research. The authors argue that integrating knowledge from the field of animal behaviour into applied research can significantly enhance the management and conservation of wildlife populations.


Recognising Individual Behaviour Differences


The paper highlights the presence of inter-individual behavioural differences within animal populations, referred to as animal personalities or behavioural phenotypes. These behavioural traits, including aggression, exploration-avoidance, activity, shyness-boldness, and sociability, are consistent over time and contexts. They often form suites of correlated traits known as behavioural syndromes. Importantly, these behavioural differences are not mere stochastic noise but have observable ecological and evolutionary consequences.


Impacts on Conservation Research Areas


The authors discuss ten research foci commonly addressed in applied wildlife management and conservation and illustrate how animal personalities and behavioural syndromes can influence each of these areas. For instance, in the context of detection probability and trappability, individual behaviour differences can affect the efficacy of monitoring efforts and the estimation of population size and structure. Behavioural traits also influence animal movement and dispersal patterns, habitat selection, mate choice, reproductive success, parasite infection, and responses to human harvest, urbanisation, and disturbance.

Bridging the Gap


The paper highlights a disconnect between basic research on animal behaviour and its application in wildlife conservation. While the concept of animal personalities has gained traction in animal behaviour, ecology, and evolutionary biology literature, it is underrepresented in applied wildlife management and conservation studies. The authors stress the need to bridge this gap by integrating knowledge from both realms. By doing so, researchers and practitioners can gain a more comprehensive understanding of wildlife populations and make informed decisions for their management and conservation.


Implications for Conservation Practice


Animal personalities and behavioural syndromes have significant implications for wildlife conservation practice. They can bias empirical estimates of population size and structure, influence resource selection models and population dynamics, impact responses to disturbance and novel environments, and affect the success of reintroduction and habitat restoration efforts. Considering individual behaviour differences is crucial in all phases of wildlife study, from study design and data collection to analysis and the development of management plans.


Moving Towards Effective Conservation


To enhance wildlife conservation efforts, the paper emphasises the importance of integrating knowledge from animal behaviour research into applied wildlife management and conservation. By recognising and considering individual behaviour differences, researchers and practitioners can gain a deeper understanding of population dynamics, resource utilisation, responses to environmental changes, and other key aspects necessary for effective management and conservation.


Incorporating individual behaviour differences, such as animal personalities and behavioural syndromes, is a crucial component of applied wildlife conservation research. This paper highlights the significance of these behavioural traits in population-level processes and ecological interactions, and their influence on various aspects of wildlife management. By bridging the gap between basic and applied research, we can ensure that wildlife conservation practices are informed by a comprehensive understanding of animal behaviour. Ultimately, by recognising and considering individual behaviour differences, we can pave the way for more effective management, conservation, and recovery of wildlife populations.
