Rest to roam: behavioural adaptations of tigers in anthropogenically altered landscapes.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLarge carnivores in human-dominated landscapes face significant risks from increased anthropogenic pressure, making it crucial to understand their movement behaviour for conservation strategies.
methodsWe used conventional and generalised hidden Markov models (HMMs) to analyse GPS telemetry data collected from 2016 to 2022 on 15 subadult tigers to classify behavioural states across three life stages (pre-dispersal, dispersal, post-dispersal) in the Eastern Vidarbha Landscape, India. We further examined how intrinsic and extrinsic factors influenced transitions between these behavioural states.
resultsThree distinct behavioural states were identified: resting (stationary movement with very short step lengths), area-restricted movement (tortuous movement with short to intermediate step lengths), and travelling (highly directional movement with long step lengths). During the pre-dispersal phase, tigers displayed exploratory movement within their natal range, with significant emphasis on area-restricted movement (42.10%), followed by travelling (30.47%), and resting (27.42%). Travelling peaked at dusk and showed the highest probability of occurrence throughout the night until dawn and exhibited faster movement in areas with high human density. Area-restricted movement was most frequent during the day and peaked between 09:00-11:00 h, while resting showed the highest probability between 22:00-23:00 h. Dispersing tigers allocated their activity budget equally among resting (32.09%), area-restricted movement (35.77%), and travelling (32.14%), as they navigated fragmented landscapes comprising of forests, wildlife corridors, agricultural fields, and human settlements. They exhibited faster, directed movements in low-cover areas and increased step lengths in fragmented, non-forest habitats, with a greater likelihood of travelling at dusk and night. Tigers in the post-dispersal phase had stable home ranges and maintained well-defined territorial boundaries. During area-restricted movement, they exhibited longer step lengths in forest habitats and faster travel speeds in a human‒agricultural matrix. Moreover, they tended to rest at high temperatures and travelled more when the temperatures were between 20 and 30 °C.
conclusionsOur study provides crucial insights on tiger movements in human-dominated landscapes across different life stages and habitats. Understanding their behavioural patterns and implementing effective conservation efforts can ensure the long-term survival of tigers and their coexistence with humans.
