Researchers tracked more than 440 wild female Asian elephants over a 12-year study in Sri Lanka to evaluate how population declines alter behavioral dynamics. The findings, published in the journal Science, revealed that gradual individual losses eventually pushed the herds beyond a critical social tipping point. Outside the 119-square-mile national park, compounding factors like human conflict, poaching, and disrupted habitat connectivity continue to accelerate these demographic shifts.

Elephants Found to be Increasingly Isolated, Leading to Fractured Social Networks
With a troubling decline in the population, researchers warn of a tipping point for the highly social animals

Key Takeaways
- UC San Diego researchers studied the social dynamics of hundreds of Asian elephants over more than a decade in Sri Lanka.
- They tracked a decrease in the population of the highly social animals that has led to fractured and more isolated communities.
- Surpassing a social “tipping point,” they warn, can be detrimental to the future of the animals.
Humans and many other social animals thrive in well-established community networks. Asian elephants are one example of a species that flourishes in groups that work together to access food and care for their young, among other social bonds.
University of California San Diego scientists in the School of Biological Sciences studying the intricacies of Asian elephant community structures have documented a troubling downturn in the population of the animals resulting in fractured social communities. Their study is published on the cover of the November…
Emerging from A*STAR in November 2025, Healbac is engineering stem-cell-derived antimicrobial molecules that burst bacterial membranes to bypass standard drug-resistance mechanisms. The biotechnology venture aims to provide veterinarians with early intervention treatments for animal ear and skin conditions before traditional systemic antibiotics become necessary. This veterinary rollout establishes practical validation for a versatile platform that may eventually eliminate chemical additives from processed food su…
Researchers using 3D photogrammetry at Balquhidder Parish Church discovered that an elaborately carved slab was repeatedly altered over centuries before marking an eighteenth-century burial. The presence of early liturgical carvings suggests the monument was originally crafted to honor an important early medieval cleric. These findings reveal a complex history of reuse that continued through the later addition of secular imagery.
Researchers monitored nearly five hundred American youths over multiple years to evaluate how hostile, punitive control influences adolescent behavioral development and emotional health. Youths facing high levels of this rigid discipline proved increasingly prone to justifying rule violations and bullying. These findings show that heavy-handed home environments directly foster attitudes that excuse disruptive social conduct.
