National and intergovernmental regulation of fisheries has not been sufficient to prevent many failures of fisheries management at the global scale. International trade in fisheries is of the order of USD 10 billion annually, mostly from “South” to “North”. Developing countries, particularly in Asia, benefit from this trade, and domestic...
With agriculture continuing to play an ever-increasing role in our modern economy, more and more attention is being directed toward the hitherto more or less neglected finer points of crop production. In the past it has been the tendency to concentrate research on those factors which most obviously affect agricultural...
Previous research has indicated several soil-applied herbicides
are more effective by exposure to emerging shoots than from
root uptake. Studies were conducted in the greenhouse and growth
chamber to investigate effects of herbicide placement in soil on
toxicity to emerging seedlings.
In these studies, an inch of treated soil was...
Bembidion (Sloanephila) tahitiense, sp. nov., is described from Mont Mauru, an isolated massif of Tahiti Nui volcano. Based upon evidence from seven genes (four nuclear protein-coding, one mitochondrial protein-coding, two nuclear ribosomal), its sister group is the Australian B. jacksoniense Guérin-Méneville, with which it shares a synapomorphic spur on the...
This paper presents the design and evaluates the performance of a double-walled electrically aspirated radiation shield for thermometers measuring air temperature and its gradients in the atmospheric surface layer. Tests were performed to quantify its solar radiation error and wake production, and to characterize the observer effect of the forced...
Austral winter oceanographic measurements from the
northwest Australian continental shelf reveal salty water
forming evaporatively inshore, moving across the wide
shelf near the bottom and into the adjacent open ocean when
the shelf edge alongshore flow is equatorward. The salt
tongue is absent during more normal conditions, when the
poleward...
