Article Synopsis
- - A healthy ecosystem requires a balanced relationship between carnivores and their prey, which this study explores through the predator-prey power law equation in Nepal's lowland protected areas.
- - The study found that predator biomass density increases about three times for every five times the increase in prey biomass density, creating a lopsided biomass pyramid that supports the idea of predator reliance on prey.
- - By examining competition between predators, the research suggests that maintaining the power law exponent can help scientists better understand the growth patterns in ecological communities, leading to new research opportunities.
Article Synopsis
- Human-wildlife conflict (HWC) research in high-altitude areas is limited, but this study focuses on the Gaurishankar Conservation Area in Nepal, examining the rising conflict trends involving leopards and Himalayan black bears over the past decade.
- The analysis reveals that goats are the primary livestock attacked, with the Dolakha district reporting the most incidents, underlining the urgent need for mitigation strategies, as livestock attacks account for 85% of compensation claims.
- The study suggests various solutions to reduce conflicts, such as increasing prey populations, community education, and implementing insurance programs, highlighting the research's importance for local communities and biodiversity conservation.
Human activities can influence behaviors of predators and prey, as well as predator-prey interactions. Using camera trap data, we investigated whether or to what extent human activities influenced behaviors of predators (tigers and leopards) and prey (sambar deer, spotted deer, wild boar, and barking deer), and predator-prey interactions in the Barandabhar Corridor Forest (BCF), Chitwan District, Nepal. A multispecies occupancy model revealed that the presence of humans altered the conditional occupancy of both prey and predator species.

We estimated gharial abundance in the Rapti River, one of the major rivers in Chitwan National Park (CNP) holding the largest numbers of gharials in Nepal. The Rapti River, running across the CNP, was divided into 18 segments, each measuring ~4 km, and gharials were counted directly with three replicates.
