Wildlife Biology, EarlyView.Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Wildlife Biology, EarlyView.Methods to estimate abundance from unmarked populations of animals are widely used because of their efficiency and presumed accuracy. These methods account for imperfect detection by comparing observed data against the assumed distribution of the entire population.

Wildlife Letters, EarlyView.In the winter of 2021/2022, a winter track survey revealed 43–46 tigers (without cubs) in 5.4 thousand km2 of suitable habitats in the Southwest Primorsky Province of Russia. In the same period, a network of camera traps registered 54 adult/subadult tigers here.

Parametric flyover optimization framework
Frontiers in Built EnvironmentIntroductionRapid urbanization in Tier-II Indian cities demands systematic approaches to grade separation infrastructure. Conventional iterative design often fails to integrate geometric, economic, geological, and regulatory constraints.

Wildlife Letters, EarlyView.Asiatic black bears in Russia face conservation threats such as habitat destruction and fragmentation, which exacerbate food shortages caused by crop failures. This study explores an innovative approach to rehabilitating bears that abandon hibernation in mid‐winter due to extreme exhaustion by providing supplemental food near their den sites.

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range
Wildlife Society Bulletin, EarlyView.We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

Wildlife Society Bulletin, EarlyView.Autonomous recording units (ARUs) are increasingly used for passive acoustic monitoring, but deploying them in remote or inaccessible locations remains challenging. We developed and field‐tested a lightweight, low‐cost floating platform for drone‐assisted deployment and retrieval of ARUs in wetland interiors.

Modeling of Unsymmetrical Single-lane Roundabouts based on Stopping Sight Distance
KSCE Journal of Civil Engineering, 2019 Evaluation of the adequacy of sight distance at roundabout is usually performed graphically as no quantitative guidelines are available for the lateral clearance needs. This paper presents analytical lateral clearance models to satisfy Stopping Sight Distance (SSD) at unsymmetrical single-lane roundabouts (with different entry and exit radii).
