Multi-Band Spectrum Camera (MBSC) for Automatic Fixed-Point Reflectance Image Collection in a Crop Field

open access: yesPlant Production Science, 2011
Here we describe the configuration and operation of a field-use digital imaging system (multi-band spectrum camera, MBSC) that captures images in two spectral bands in the visible and near infrared wavelength ranges, and automatically converts and stores

Impacts of Coastal Underground Brine Exploitation on the Depletion of Shallow Brine in Beach and Neritic Zones

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract Coastal underground brine (CUB) exploitation and groundwater discharge jointly drive the depletion of beach and neritic shallow underground brine (BNSUB). BNSUB is crucial for CUB exploitation, yet its reserve remain unquantified, and the impacts of different mining models on its evolution are poorly understood.

Shifting in the shadows: Morphofunctional variations of Miconia sellowiana Naudin (Melastomataceae) associated with cave environments

open access: yesPlant Biology, Volume 28, Issue 2, Page 441-451, March 2026.
Cave environments filter plant traits, selecting thinner, smaller leaves with reduced photosynthetic and vascular structures. Abstract Caves present unique ecological conditions that influence the distribution and adaptation of species, yet studies on cave‐associated vegetation remain limited.

Determination of biogeochemical properties of marine particles using above water measurements of the degree of polarization at the Brewster angle [PDF]

open access: yes, 2007
Retrieval of biogeochemical parameters from remotely sensed data in optically complex waters such as those found in coastal zones is a challenging task due to the effects of various water constituents (biogenic, nonalgal and inorganic particles ...

Building Off‐Paddock Infrastructure: Insights, Decisions and Lessons Learnt from Southern New Zealand Dairy Farmers

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
Many regions across New Zealand experience cold, wet winters with low pasture growth. Consequently, farmers often rely on winter forage crops to feed cows, resulting in challenges with animal welfare, environmental damage and operational difficulties. Despite the potential of off‐paddock facilities to overcome negative outcomes of crop wintering, only ...
