Workers in many insect societies interact via body contact with their nest mates, and social biting and other forms of contact may play a general role in regulating task performance. Here I present evidence that social biting affects task performance without direct reproductive conflict in Polybia occidentalis, a swarm-founding eusocial wasp. Polybia occidentalis workers engaged in social bitin...

Section Firmae of subgenus Pseudokygrocybe within Hygrocybe is characterized by short parallel to subparallel hyphae that make up the lamellar trama. Section Firmae is further defined by the presence of dimorphic basidia and spores on the same basidiome (Heinemann 1963). Several species classified in section Firmae deviate from other members of the subgenus Pseudohygrocybe, however, in having l...

Schwanniomyces occidentalis invertase is an extracellular enzyme that hydrolyzes sucrose and releases beta-fructose from various oligosaccharides and essential storage fructan polymers such as inulin. We report here the three-dimensional structure of Sw. occidentalis invertase at 2.9 A resolution and its complex with fructose at 1.9 A resolution. The monomer presents a bimodular arrangement com...

BACKGROUND Oleaginous yeast species are an alternative for the production of lipids or triacylglycerides (TAGs). These yeasts are usually non-pathogenic and able to store TAGs ranging from 20 % to 70 % of their cell mass depending on culture conditions. TAGs originating from oleaginous yeasts can be used as the so-called second generation biofuels, which are based on non-food competing "waste c...

Specimens of Ruppia from all eleven Nebraska counties in which it is known fall into two groups: R. occidentalis in alkaline Sandhills waters and R. maritima in saline waters of the Platte River Valley and Lancaster County.
