Many obligate symbiotic fungi are difficult to maintain in culture, and there is a growing need for alternative approaches to obtaining tissue and subsequent genomic assemblies from such species. In this study, the genome of Elaphomyces granulatus was sequenced from sporocarp tissue. The genome assembly remains on many contigs, but...
There were two viable theories of generation, preformation
and epigenesis, existing in the Seventeenth and
Eighteenth Centuries. Due to their irreconcilable nature,
they were often at loggerheads during this time interval.
The status of these generation theories can be effectively
understood in terms of Thomas Kuhn's conception of preparadigm
science....
Cellulose nanocrystals (CNCs) have received considerable attention over the last ten years because CNCs can be produced from renewable materials such as straw, wood, cotton, and sea animals (tunicates). CNCs are slender rods with high aspect ratios (10-100) and the final dimensions of the CNCs depend on the starting material....
Large-scale poisoning events are common to scavenging bird species that forage communally, many of which are in decline. To reduce the threat of poisoning and compensate for other persistent threats, management, including supplemental feeding, is ongoing for many reintroduced and endangered vulture populations. Through a longitudinal study of lead exposure...
Sand dams – low-head dams built in ephemeral streambeds that store water within saturated sediments – are a proven means to increase water supplies for rural communities in arid and semiarid regions. Water percolates into the reservoir-impounded sediments during wet season rains and can subsequently be extracted during the dry...
The seasonal concentration, turnover and mode of accumulation
of ³²P by the juvenile starry flounder in Alder Slough, a small eco-system in the Columbia River Estuary, was examined during 1969 and
1970.
Levels of ³²P and concentrations of total P were measured to
permit computation of specific activities (nCi³²P/g total...
The pea crab Fabia subquadrata is frequently found as a symbiont
of mussels, living within the mantle cavity. This study examined
the nature of this symbiotic relationship by recording the pattern
of distribution of individuals in a mussel bed, testing responsiveness
to host secretions, and observing the feeding mechanics and...
