Shoot apex senescence is defined as the collective progressive
and deteriorative processes which ultimately terminate the functional
life of the shoot apex. Senescence of shoot apices of Pisum sativum
L. 'Alaska' as measured by cessation of stem elongation was delayed

The thermophilic aldolase from Bacillus stearothermophilus
(NCA 2184) has been purified to a specific activity of 45.5 μ-moles
of fructose-1, 6-diphosphate cleaved per minute per mg of enzyme,
representing a 624-fold increase over the crude extract. The preparation appeared to be homogenous by sedimentation velocity ultra-centrifugation
and by a specific...
Perloline levels have been associated with poor animal
performance on tall fescue pastures. Animal performance is
low when perloline levels are high. High perloline levels
are reported during hot, dry weather and increased N
fertilization. Tall fescue perloline levels appear to be
affected by genetic and environmental differences. Positive
associations...
The Great Salt Lake is typical of Great Basin
and other arid land saline lakes in morphological and
chemical characteristics. As with other terminal
lakes, the level of Great Salt Lake is determined by
the variable weather patterns that are typical of
arid and semi-arid regions. Because of it's flat,...
This document partially addresses the Wetlands component of San Juan County’s Critical Areas Ordinance (CAO). Drawing from a foundation in best available science, it describes important functions performed by the County's wetlands, effects of various activities on those functions, and strategies for protecting wetland functions from impacting activities, with an...
One pressing economic, societal and environmental issue affecting commercial fisheries is the production of undesirable outputs. In fisheries, undesirable outputs often arise because of economic or regulatory discarding of commercial species and/or the incidentally caught or ‘take’ of protected species, such as sea turtles and marine mammals. In fisheries, undesirable...
