Uncertainty assessment for a novel optically shallow water radiometric acquisition platform
Limnology and Oceanography: Methods, EarlyView.Abstract We present a novel motorized platform, a custom‐built jet‐ski designed for acoustic and radiometric measurements in optically shallow coastal waters. This platform integrates in‐water radiometers with single‐beam and multi‐beam acoustic sensors, along with a suite of active and passive instruments (conductivity‐temperature‐depth, fluorescence,

Breynia phuongiana (Phyllanthaceae), a new species from the Central Highlands of Vietnam
Nordic Journal of Botany, EarlyView.A new species, Breynia phuongiana (Phyllanthaceae subgen. Sauropus), is described and illustrated from the Central Highlands of Vietnam. It is morphologically similar to B. beillei, B. bonii, and B. thorelii, but differs in having oblong‐elliptic leaves, sepals marked with reddish striations, an androphore exceeding 1 mm in length, and distinctly ...

Taxonomic reappraisal of the mangrove genus Avicennia (Acanthaceae) in India
Nordic Journal of Botany, EarlyView.A taxonomic reappraisal of the mangrove genus Avicennia in India was undertaken through extensive field surveys and critical examination of herbarium specimens. Three taxa, Avicennia alba, Avicennia marina subsp. marina, and Avicennia officinalis, are described in detail. A synonymic list was compiled using the World Checklist of Vascular Plants (WCVP)

Occurrence, morphology and growth of understory saplings in Swedish forests [PDF]
, 2004 Growing demands for a multipurpose forestry leads to increased use of silvicultural systems that avoid clear-cutting. Regeneration in such systems is based on establishment and ingrowth of new seedlings under a more or less closed canopy.
