A Sticky Situation: Functional Responses Of Mast Cells To Acidic pH
(Biology, 2008-04-22)
Precise regulation of extracellular pH is critical for proper function of many cellular activities. Minor fluctuations in pH can have profound effects on ion transport, receptor function, and cellular secretions. This work ...

(Biology, 2008-09-17)
The genus Gonatodes (family Sphaerodactylidae) is a diverse of group of about 20 species currently recognized of mostly diurnal geckos that are collectively distributed from southern Mexico to Brazil and Bolivia, and also ...
Comparative Thermal Biology And Associated Niche Differentiation Among the Five-Lined Skinks
(Biology, 2008-09-17)
Three species of five-lined skinks (Plestiodon fasciatus, P. laticeps, and P. inexpectatus) occur in regional sympatry across much of the Southeastern United States. These closely-related species, at one or more levels of ...
The Control Of Gene Expression By High Light Stress In Cyanobacteria Through The Apparent Two-component NblS-RpaB Signal Transduction Pair
(Biology, 2008-09-17)
In nature photosynthetic organisms including cyanobacteria are dependent upon their
ability to acclimate to changes in environmental conditions including light and nutrient levels. The
NblS sensor kinase of the cyanobacterium ...
How Herbivores Affect Plant Growth, Community Structure And Litter Decomposition In Alaskan Tundra: Implications For Responses To Climate Change
(Biology, 2008-09-17)
Increasing atmospheric carbon dioxide (CO2) concentrations have caused higher air temperatures in the Arctic. Because arctic organisms are temperature limited, warmer conditions lead to higher decomposition and nutrient ...
Efficacy Of A Series Of Organotin Polymers As Anticancer And Antiviral Drugs
(Biology, 2008-04-22)
Anticancer drugs have been shown to have antiviral abilities as well. The two types of diseases are similar in that they hold the cell in a continued growth phase. Therefore, if a drug has anticancer activity, it could ...
Phylogeography And Geographical Variation Of Behavioral And Morphological Characteristics In Paruroctonus boreus
(Biology, 2008-09-17)
Specimens of Paruroctonus boreus were collected from twenty-four sites to assess the geographic variation in behavioral, morphological and molecular traits. Statistical analyses showed males demonstrated a positive response ...
