A feasibility study: Forest Fire Advanced System Technology (FFAST) [PDF]
The National Aeronautics and Space Administration/Jet Propulsion Laboratory and the United States Department of Agriculture Forest Service completed a feasibility study that examined the potential uses of advanced technology in forest fires mapping and ...

Ecology and Evolution, Volume 16, Issue 5, May 2026.Our paper addresses the problem of “How to predict where a tree can be found from its traits?” We show that wood density, bark thickness, maximum height and seed mass combine for a useful model of tree distributions. ABSTRACT Trait‐Species Distribution Models (trait‐SDM) help to understand the importance of plant strategies to niches, assess their ...

Ecography, Volume 2026, Issue 5, May 2026.The ecological niche concept is fundamental to understanding species distributions but often overlooks the demographic processes shaping said distributions. Conversely, demographic theory has traditionally neglected how vital rates vary and covary across environments, limiting our understanding of population dynamics across species' ranges.

Hydrological Processes, Volume 40, Issue 5, May 2026.The extreme flooding of April 2024 caused a complete “geomorphic reset”, resulting in a 24% widening of the channel and a transition to critical or supercritical flow regimes. The energy of the event broke through the stable armouring layer, reducing the armouring ratio from 7.9 to 4.9 and intensely removing fine sediments from the subsurface.

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR
River Research and Applications, Volume 42, Issue 4, Page 886-900, May 2026.ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.

Hydraulic Effects of Channel Realignment and Floodplain Reconnection in a Headwater Stream
Water Resources Research, Volume 62, Issue 5, May 2026.Abstract Channel realignment and floodplain reconnection are increasingly used as nature‐based solutions for flood management, yet their hydraulic effects remain poorly quantified in field settings of moderate‐gradient, small order channels. This study examines the impact of such interventions on hydraulic response in a headwater catchment, Goldrill ...

Methods in Ecology and Evolution, Volume 17, Issue 5, Page 1556-1584, May 2026.Abstract The rapid expansion of biodiversity data presents new opportunities to understand and forecast biosphere dynamics. However, disparate and dispersed data, taxonomic and geographic inconsistencies, pervasive quality issues, and a lack of reproducable workflows hinder synthesis, introduce biases and limit accurate assessment of biodiversity ...

Journal of Biogeography, Volume 53, Issue 5, May 2026.ABSTRACT Aim Southern Africa's remarkable environmental heterogeneity drives high biodiversity and endemism, yet biogeographical regionalisations often overlook invertebrates despite their ecological significance. This study presents a comprehensive regionalisation of southern Africa using tenebrionid beetles (Coleoptera: Tenebrionidae), a diverse and ...

Journal of Communications Software and Systems, 2018 In this paper, a novel approach for an automatic object detection and localisation on aerial images is proposed. Proposed model does not use ground control points (GCPs) and consists of three major phases.
