BIEN: A biodiversity informatics ecosystem advancing open and reproducible workflows for plant observation, plot and trait data

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 ...

Multi-algorithm Swath Consistency Detection for Multibeam Echosounder Data [PDF]

, 2007
It is unrealistic to expect that any single algorithm for pre-filtering Multibeam Echosounder data will be able to detect all of the “noise in such data all of the time. This paper therefore presents a scheme for fusing the results of many pre-filtering

A new method to control the invasive sun corals (Tubastraea spp.): Underwater compressed‐air blasting

Ecological Solutions and Evidence, Volume 7, Issue 2, April/June 2026.
Underwater compressed‐air blasting is a novel method developed to control invasive sun corals (Tubastraea spp.). The technique removes coral soft tissue without fragmenting colonies, reducing the risk of regeneration and accidental spread. This approach offers a safer and practical tool for managing invasive corals in natural reefs and biofouling ...

‘EcoCleanR': enhancing data quality of biogeographic ranges with application for marine invertebrates

Ecography, Volume 2026, Issue 3, March 2026.
Published distribution data, while invaluable for understanding species' biogeography, often suffer from limitations such as dated and static representations of ranges, a bias toward latitudinal information, and lack of resolution in sampling frequency and variation in abundance throughout a species' distribution.

Development of portable microfading spectrometers for measurement of light sensitivity of materials [PDF]

, 2011
Microfading was originally designed for efficiently detecting extremely light-sensitive materials on objects in situ to determine the appropriate exhibition lighting conditions. By focusing an intense beam of light to a tiny submillimetre sized spot and
