A Phase-Congruency-Based Scene Abstraction Approach for 2D-3D Registration of Aerial Optical and LiDAR Images

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Registration of aerial images to enrich 3-D light detection and ranging (LiDAR) points with radiometric information can enhance the capability of object detection, scene classification, and semantic segmentation.

Geoarchaeological site documentation and analysis of 3D data derived by terrestrial laser scanning [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
Terrestrial laser scanning was conducted to document and analyse sites of geoarchaeological interest in Jordan, Egypt and Spain. In those cases, the terrestrial laser scanner LMS-Z420i from Riegl was used in combination with an accurate RTK-GPS for ...

When wolves aren't enough: revisiting trophic cascades in northern Wisconsin

open access: yesOikos, Volume 2026, Issue 8, August 2026.
Elimination of top predators has allowed large herbivores to flourish in many terrestrial ecosystems, transforming food webs and ecosystem functions. Restoration of large predator communities is hoped to reverse negative effects of this trophic downgrading, but evidence for such effects is elusive.

Flowering out of sync: Climate change alters the reproductive phenology of Terminalia paniculata in the Western Ghats of India

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1322-1333, July 2026.
Understanding how climate change impacts the plant life cycle is critical for maintaining biodiversity and ecosystem services. Our findings suggest that Terminalia paniculata Roth, a common tropical deciduous tree species in the Western Ghats, is now flowering and fruiting at more scattered times than it used to in the past.

Digitisation of herbarium specimens to the benefit of research: An African perspective focusing on South Africa and Western Indian Ocean Island states

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1042-1056, July 2026.
Botanical exploration, discovery and conservation rely heavily on access to herbarium collections. Recently, digital access to label information, including georeferenced locality data, and images of herbarium specimens available online have greatly increased usage of herbarium specimen data.

Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1345-1356, July 2026.
The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

Flow‐pattern evolution of the Scandinavian Ice Sheet indicated by the subglacial lineation record over Norway, Sweden and Finland

open access: yesBoreas, Volume 55, Issue 3, Page 612-669, July 2026.
We present a 25‐stage reconstruction of the ice‐flow pattern evolution of the Scandinavian Ice Sheet based on mapping and analysis of ~240 000 subglacial lineations and lineation fields across Norway, Sweden, Finland, and parts of NW Russia. Our reconstruction uses a glacial geomorphological inversion approach, in which we generated 611 individual ...

Soil Diversity and Climate: An Overview of Profile Data and Acquisition With the WoSIS Global Legacy Dataset

open access: yesEuropean Journal of Soil Science, Volume 77, Issue 4, July/August 2026.
ABSTRACT Soil profiles are the primary field evidence from which pedogenesis, soil classification and land‐use effects are interpreted, yet their availability remains uneven across climates and land‐cover contexts. Here, we analyse the World Soil Information Service (WoSIS) 2023 snapshot together with Copernicus Global Land Cover 2015 and the global ...

Stepping Up or Stepping Out? Sustainable Livelihood Resilience, Heterogeneous Strategies and Poverty Alleviation Among Retired Fishermen in the Yangtze River Basin

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT The ‘Ten‐Year Fishing Ban’ policy in the Yangtze River Basin has compelled over 230,000 fishermen to cease fishing and transition to alternative livelihoods, making their post‐ban livelihood development critical to the policy's long‐term effectiveness. Drawing on household survey data from Hubei and Hunan provinces—which account for nearly 40%
