Overall, this study sheds light on the intricate decision-making processes of African elephants when it comes to finding food and navigating their environment. By understanding how these majestic creatures balance energy costs with resource availability, conservation efforts can be better tailored to protect their habitats and ensure their survival in the face of increasing human activity and climate change.
The researchers behind this study hope that their findings will not only benefit African elephants but also serve as a model for studying the movement patterns of other wildlife species. By delving into the complex interactions between animals and their environments, scientists can gain valuable insights into how best to protect biodiversity and preserve the delicate balance of ecosystems around the world.
As we continue to learn more about the behaviors and needs of elephants and other wildlife, we can work towards creating a more sustainable future where humans and animals coexist harmoniously. Through careful observation and research, we can ensure that future generations will still have the privilege of witnessing these incredible creatures roam freely in their natural habitats.

African elephants, the largest land animals on Earth, face the challenge of finding food efficiently to survive. These endangered pachyderms must consume up to 330 pounds of low-calorie vegetation daily to sustain themselves. However, the strategies they use to locate the best food sources remain a mystery. A recent study involving over 150 elephants reveals that these gentle giants plan their movements based on resource availability and energy costs, highlighting the importance of every step they take.
Emilio Berti, an ecologist from the German Centre for Integrative Biodiversity Research (iDiv) and Friedrich-Schiller-University Jena, emphasizes the significance of these new findings in guiding conservation efforts and habitat restoration initiatives. By considering the energy costs associated with elephant movements, conservationists can better plan dispersal corridors and protect the habitats of these majestic creatures.
Every step you take
The African forest elephant (Loxodonta cyclotis) and the African savanna elephant (Loxodonta africana) are listed as Critically Endangered and Endangered, respectively, by the International Union for Conservation of Nature (IUCN). With human activities causing habitat fragmentation, understanding how elephants navigate their landscapes is crucial for effective conservation strategies. These elephants can travel long distances, spanning between 31 to 121 miles in a single day, yet the factors influencing their movements have not been fully understood.
Researchers from the University of Oxford, iDiv, and Friedrich Schiller University Jena utilized GPS tracking data from 157 African elephants in northern Kenya, collected by the conservation organization Save the Elephants from 1998 to 2020. The data revealed that elephants exhibit a strong preference for areas with lower movement costs, avoiding rough terrain and steep slopes to conserve energy. This suggests that elephants are capable of making informed decisions about the most efficient paths to take based on their surroundings.
Furthermore, elephants show a preference for areas with higher vegetation productivity, indicating their ability to select resource-rich environments. Water sources also play a critical role in their movement decisions, with individual elephants exhibiting varying responses to water availability. These findings suggest that elephant movement choices are more complex than simply seeking the nearest water source.
When it comes to speed, elephants moving at slower paces demonstrate a stronger avoidance of energetically costly terrain, with a majority of individuals avoiding rough or steep areas. This behavior indicates that elephants carefully balance effort and energy efficiency during their journeys, akin to birds utilizing thermal uplifts to reduce flying costs.
Enter ENERSCAPE
To analyze the tracking data, researchers employed a modeling method called ENERSCAPE, which estimates the energy costs of movement based on body mass and terrain slope. By integrating these estimates with satellite data on vegetation productivity and water availability, the team constructed detailed energy landscapes to elucidate elephants’ movement decisions.
Additionally, a statistical approach known as step-selection functions was utilized to assess how elephants selected their paths. By comparing visited locations with nearby unselected areas, the researchers identified environmental factors influencing elephants’ movement decisions and habitat selection.
These new insights can inform conservation efforts by aiding in the design of protected areas and migration corridors to mitigate human-elephant conflicts. Understanding individual differences in habitat preferences, particularly regarding water access, is crucial for effective conservation strategies. Moreover, these findings can help predict how elephant movements may respond to climate change, as shifts in temperature and rainfall patterns impact energy costs and resource availability.
Future research aims to refine energy landscape models by incorporating seasonal variations, human disturbances, and climate change impacts on elephant movements. By delving deeper into elephants’ habitat usage, researchers strive to gain a comprehensive understanding of these animals’ decision-making processes.
In conclusion, this study sheds light on the intricate behaviors of African elephants and their adaptive strategies for survival in challenging environments. By unraveling the complexities of elephant movements, scientists can better tailor conservation efforts to protect these iconic species and preserve biodiversity for future generations.
Saving energy whenever possible is not only good for the environment, but it can also save you money in the long run. By making small changes to your daily habits and being mindful of your energy consumption, you can make a big difference in reducing your carbon footprint. Here are some tips on how to save energy in your daily life:
1. Turn off lights and electronics when not in use: One of the simplest ways to save energy is to turn off lights and electronics when you are not using them. This includes computers, televisions, and other devices that are plugged in but not actively being used. By turning off these devices, you can reduce energy waste and lower your electricity bill.
2. Use energy-efficient appliances: When shopping for new appliances, look for energy-efficient models that are certified by Energy Star. These appliances are designed to use less energy while still providing the same level of performance. By replacing old, inefficient appliances with Energy Star certified ones, you can save money on your energy bills and reduce your overall energy consumption.
3. Adjust your thermostat: Heating and cooling your home accounts for a significant portion of your energy usage. To save energy, consider adjusting your thermostat by a few degrees depending on the season. In the winter, lower your thermostat and wear warmer clothing to stay comfortable. In the summer, raise your thermostat and use fans to circulate air. You can also invest in a programmable thermostat to automatically adjust the temperature based on your schedule.
4. Seal drafts and insulate your home: Proper insulation and sealing drafts can help to keep your home at a comfortable temperature without using excess energy. Check for air leaks around windows, doors, and other openings, and use weather stripping or caulk to seal them. Adding insulation to your walls, attic, and floors can also help to reduce heat loss in the winter and keep your home cooler in the summer.
5. Use natural light and ventilation: Take advantage of natural light during the day by opening curtains and blinds to let in sunlight. This can help to reduce the need for artificial lighting and lower your energy usage. Similarly, use natural ventilation to cool your home by opening windows and using fans instead of relying on air conditioning.
By incorporating these energy-saving tips into your daily routine, you can make a positive impact on the environment and save money on your energy bills. Small changes can add up to significant energy savings over time, so make an effort to be mindful of your energy consumption and make smart choices to reduce waste.
