VII.—Some apparently undescribed Neotropical Homoptera

An Apparently Undescribed Infectious Exanthem *

During the past few years, patients with an unidentified acute febrile illness have appeared on the wards of the New Haven Hospital. They present similar signs and symptoms. We have been unable to recognize this syndrome as that of any of the known infectious diseases. We believe that it may be a new disease and we are taking this opportunity to report eleven cases seen in the past five years, ...

Social Behavior and Communication in the Neotropical Cicada Fidicina mannifera (Fabricius) (Homoptera: Cicadidae)

We investigated signalling behavior in relation to social context in the cicada Fidicina mannifera. Four types of acoustic signals were recorded from males: songs, calls, low-amplitude songs, and disturbance sounds. Signal types were similar in frequency and fine temporal structure, but differed markedly in gross temporal structure. Songs and calls were the most frequently observed signals, and...

A previously undescribed tubulin binder.

Microtubules (MTs) are key components of the cytoskeleton for all eukaryotes and are vital for cellular processes such as mitotic spindle formation, intracellular transport, vesicle formation, cellular signaling, and migration. These functions depend on the dynamic nature of MTs, which arises from the polymerization and depolymerization events of individual heterodimers, made up of αand β-tubul...

The Phylogeny of the Homoptera

A previously undescribed pathway for pyrimidine catabolism.

The b1012 operon of Escherichia coli K-12, which is composed of seven unidentified ORFs, is one of the most highly expressed operons under control of nitrogen regulatory protein C. Examination of strains with lesions in this operon on Biolog Phenotype MicroArray (PM3) plates and subsequent growth tests indicated that they failed to use uridine or uracil as the sole nitrogen source and that the ...
