The Brahmagiri-Nilgiri Eastern Ghats complex in Kerala is a key landscape for Asian elephant conservation and supports the largest single breeding population across their range. However, negative encounters between people and elephants are increasing in frequency and have become a prominent cause for concern. Despite this, the use of predictive distribution models to map the spatio-temporal patterns of human-elephant interactions across the landscape remains poorly explored. Compiling 1942 individual conflict incidents from compensation records, we dynamically extracted 16 ecological and anthropogenic variables identified in the literature as important drivers of interactions between people and Asian elephants. Using an ensemble modelling framework incorporating 10 algorithms, we constructed predictive distribution models for the wet and dry seasons from 2011 to 2023 to map the spatiotemporal distribution of regions at consistent risk of negative human-elephant interactions. Final consensus models achieved a mean accuracy of 0.91 (AUC) and 0.73 (TSS) respectively and suggested that the top predictor in influencing interactions is human population density. Regions within and adjacent to the Wayanad Wildlife Sanctuaries (I and II) have the highest predicted likelihood of interactions, however risk-level differs according to season. During the dry season, areas including Kidanganad, Nulpuzha, and Pulpalli, within the Kurichiat, Muthanga, and Sulthan Battery Forest ranges, were identified as having the largest land area at risk. Conversely during the wet season, the Tirunelli and Trisshaleri areas in the Tholpetty forest range demonstrated the highest risk.

The average period of incarceration was 8 years, ranging from 6 months for illegal entry into the protected area to 30 years for possession of elephant tusks and rifles. Most court cases were filed during the dry season from June to October, and the general trend indicated a decline in cases filed from 2014 to 2022. Evidence tendered before the court indicated that wildebeest (<em>Connochaetes taurinus</em>) are the most poached species and wire snare entanglement was the most used technique to trap and catch ungulates. Furthermore, the evidence presented and the interview results indicate that poaching was not only a subsistence activity for bushmeat or economic gain, but also involved other ethnozoological aspects.

Results revealed significant niche overlap, with Schoener’s D values ranging from 0.55 (summer) to 0.66 (winter), indicating heightened competition risks during overwintering periods. <em>L. polyactis</em> exhibited broader niche breadth and greater salinity adaptability, whereas <em>L. crocea</em> displayed niche conservatism, relying on stable coastal habitats (40–70 m depths). Seasonal drivers differed: mixed layer thickness shaped summer distributions, while temperature and sea surface height dominated winter patterns. Overlap zones (4.73 % of the study area) concentrated in Zhejiang’s coastal waters, coinciding with key fishing grounds. Vertical stratification and dietary differences likely reduced direct competition, but <em>L. crocea</em>’s narrow niche breadth increases its vulnerability to environmental change.

However, bamboo nitrogen content varies dramatically across species, seasons, elevations, and disturbance gradients. This perspective argues that the absence of nitrogen criteria constitutes a critical blind spot in red panda conservation.

Endogenous mutation rates are slow, particularly as natural populations decline and fragment. Phenotypic plasticity has its limits, particularly at extremes of physiological tolerance. Migration is only effective if appropriate habitat exists within dispersal abilities. Introgressive hybridization, an important element of natural diversification, has been effective means to generate novel vigorous phenotypes. Assisting phenotypic diversification through introgressive hybridization among suites of partially interfertile species could be an effective conservation strategy to enable endangered species to adapt and respond. These suites of species function as a geographically and taxonomically networked syngameon, allowing exchange of advantageous traits, replenishing genetic diversity, and restoring lost ecological and physiological functions. Phenotypic outliers within species - individuals with rare but beneficial traits - are important for maintaining adaptive potential within these networks. Fortunately, species typically maintain their cohesive identities given natural levels of interspecific genetic exchange. Experimental programs and theoretical studies will be essential to explore the impacts of accelerated introgressive hybridization within defined syngameons, with the goals of addressing uncertainties and refining methods. As environmental changes accelerate, promoting phenotypic diversification through hybridization offers a proactive strategy to maintain adaptive capacity.

Although we observed some behaviours associated with agonism and anxiety from both sides, the presence of dogs at close proximity was mainly tolerated. This contrasts with data from populations inhabiting protected areas where geladas typically exhibit flight responses to encounters with dogs. These differences between populations hint at gelada behavioural plasticity to adapt and live in human-impacted environments with limited alternative feeding sites.
