Species' geographic ranges are limited by climate and species interactions. Climate is the prevailing explanation for why live only within narrow elevational in megadiverse biodiverse tropical mountains, but competition can also restrict species' ranges. We test contrasting predictions of these hypotheses conducting a global comparative birds' range sizes 31 montane regions, using more than 4.4 million citizen science records from eBird to define each region. find strong support that competition, not climate, leading driver These results highlight importance interactions shaping Earth's hottest biodiversity hotspots.

Biotic interactions play a fundamental role in shaping multitrophic species communities, yet incorporating these into distribution models (SDMs) remains challenging. With the growing availability of interaction networks, it is now feasible to integrate SDMs for more comprehensive predictions. Here, we propose novel framework that combines trophic networks with Bayesian structural equation models, enabling each be modeled based on its predators or prey alongside environmental factors. This addresses issues multicollinearity and error propagation, making possible predict distributions unobserved locations under future conditions, even when predator are unknown. We tested validated our realistic simulated communities spanning different theoretical ecological setups. scenarios. Our approach significantly improved estimation both potential realized niches compared single SDMs, mean performance gains 8% 6%, respectively. These improvements were especially notable strongly regulated by biotic factors, thereby enhancing model predictive accuracy. supports integration various SDM extensions, such as occupancy integrated offering flexibility adaptability developments.

ABSTRACT Continental islands have long been used as ecological models for understanding species assembly dynamics in isolated habitat fragments. But competition or colonisation constraints might be different to mainland populations, manifesting expanded contracted ranges across a geographic distribution of comparison population range. Here, we demonstrate that plants on coastal do not experience release due lack competition, but rather range at the cool edge cross‐continental dataset 843 small spanning contrasting environments fringing Australian coast. We found their averaged 2.2°C warmer mean annual temperature, about 4–500 km nearer equator. The tendency colonise suggests may struggle track niche poleward climate shifts over fragments mainland.
