During spring and early summer, shrub- and herbaceous-level vegetation provides nesting and foraging habitat for many shrub-habitat birds. We examine relationships among arthropod biomass and abundance, foliage leaf surface area and weight, vegetation ground cover, soil characteristics, relative humidity, and temperature to evaluate what factors may influence arthropod food resources for birds.

Rotavirus nonstructural protein 4 (NSP4) is known to function as an intracellular receptor at the endoplasmic reticulum (ER) critical to viral morphogenesis and is the first characterized viral enterotoxin. Exogenously added NSP4 induces diarrhea in rodent pups and stimulates secretory chloride currents across intestinal segments as measured in Ussing chambers. Circular dichroism studies further reveal that intact NSP4 and the enterotoxic peptide (NSP4114-135) that is located within the extended, C-terminal amphipathic helix preferentially interact with caveola-like model membranes. We now show colocalization of NSP4 and caveolin-1 in NSP4-transfected and rotavirus-infected mammalian cells in reticular structures surrounding the nucleus …
A New Moustache Wasp In Dominican Amber, With An Account Of Apoid Wasp Evolution Emphasizing Crabroninae (Hymenoptera: Crabronidae), Daniel J. Bennett, Michael S. Engel
A New Moustache Wasp In Dominican Amber, With An Account Of Apoid Wasp Evolution Emphasizing Crabroninae (Hymenoptera: Crabronidae), Daniel J. Bennett, Michael S. Engel
Faculty Publications
A new, extinct species of the wasp genus Lindenius (Crabroninae: Crabronini: Crabronina) is described and figured from two exquisitely preserved specimens discovered in Early Miocene Dominican amber. Lindenius paleomystax, new species, represents the first record for the tribe Crabronini in Dominican amber and the southernmost record for the genus in the New World. The unique locality and habitat data begin to reveal a more complicated natural history for the genus than that suggested by Recent taxa alone. A checklist of fossil apoid wasps in amber is provided and the new species is discussed within the context of an overview …

Food For Early Succession Birds: Relationships Among Arthropods, Shrub Vegetation, And Soil, Richard N. Conner, Daniel Saenz, Brent Burt
Food For Early Succession Birds: Relationships Among Arthropods, Shrub Vegetation, And Soil, Richard N. Conner, Daniel Saenz, Brent Burt

During spring and early summer, shrub- and herbaceous-level vegetation provides nesting and foraging habitat for many shrub-habitat birds. We examined relationships among arthropod biomass and abundance, foliage leaf surface area and weight, vegetation ground cover, soil characteristics, relative humidity, and temperature to evaluate what factors may influence arthropod food resources for birds. Relative humidity was inversely associated with arthropod biomass; as humidity increased biomass decreased (r = -0.44, P = 0.004). We failed to detect any relationships between deciduous foliage (surface area and weight) and arthropod biomass or abundance. However, both arthropod abundance (r = 0.30, P = 0.06) and …
