After accounting for body size, bats have the longest lifespan of all mammals. Little Brown Bats (Myotis lucifugus) are one of the most common and widely distributed mamm[...]

WNT5A is a secreted ligand involved in differentiation, proliferation, cell movement and apoptosis. WNT5A is often misregulated in cancer and is known to be involved in c[...]

The abundance of eleven cyanobacteria operational taxonomic units (OTUs) was assessed in six Piedmont North Carolina Lakes using real-time quantitative polymerase chain r[...]

Studies in Dictyostelium discoideum have established that the cycle of myosin II bipolar filament assembly and disassembly controls the temporal and spatial localization [...]

Honey bee queens are exceptionally promiscuous. Early in life, queens perform one to five nuptial flights, mating with up to 44 drones. Many studies have documented poten[...]

Honeybees (Apis mellifera L.) display a pronounced natural aging plasticity. The differences in aging rates between the alternative phenotypes and behavioral classes coul[...]

Honeybee colonies are highly integrated functional units characterized by a pronounced division of labor. Division of labor among workers is mainly age-based, with younge[...]

Senescence can be defined demographically as an age- dependent increase in mortality risk, or functionally as a decline in performance. The relationship between the two p[...]

The attached PowerPoint file contains images suitable for quizzes, tests, and student study aids of plant and fungi life cycles. The images are all drawn in the same form[...]

Perspectives on the role of large-effect quantitative trait loci (QTL) in the evolution of complex traits have shifted back and forth over the past few decades. Different[...]

Allometry was used to compare differential growth of the floral organs in seven species of the Marantaceae and in Canna indica. Different relative sizes of the floral par[...]

Epstein-Barr Virus (EBV) is a human herpesvirus that infects approximately 90% of the global human population. Infection with EBV is associated with several diseases, suc[...]

Understanding how changes to habitat characteristics affect behaviors is necessary to integrate biodiversity goals with land management. Managed forests are a significant[...]

Alternative reproductive tactics are common in males but rather rare in females. In this respect, ants are apparently an interesting exception. Ant queens can either star[...]

We report the results of a comprehensive investigation of the queen size dimorphism in the North American ant Leptothorax rugatulus. Employing allozymes and microsatellit[...]

The mechanical interactions of cells are mediated through adhesive interactions. In this study, we examined the growth, cellular behavior, and adhesion of MDCK epithelial[...]

Screening of a small library of natural product extracts derived from endophytic fungi of the Sonoran desert plants in a cell-based anti-HIV assay involving T-cells infec[...]

Invasive plant species are becoming a major concern because they have been found to have negative effects such as decreasing biodiversity and inhibiting growth of native [...]

Social insect colonies represent distinct units of selection. Most individuals evolve by kin selection and forgo individual reproduction. Instead, they display altruistic[...]

To enhance current knowledge on growing plants in microgravity and reduced gravity conditions (e.g., Moon, Mars), this research project aimed to find strains of the model[...]

Previous studies have shown that myosin heavy chain kinase A and B (MHKA and MHKB) are able to phosphorylate and disassemble Dictyostelium discoideum myosin II bipolar fi[...]

"There is great concern with an increase in the number of Americans who are overweight and obese. Fat cells or adipocytes play a central role in obesity. These cells are [...]

Estrogen receptor (ER) antagonists such as tamoxifen have been used successfully to treat ER+ breast cancers for more than 30 years. Tamoxifen targets the ER and blocks t[...]

Ecdysteroid regulation of gene transcription in Drosophila melanogaster and other insects is mediated by a heterodimer comprised of Ultraspiracle (USP) and one of three e[...]

Polarization microscopy was used to examine the cause of hygroscopic movement in umbellet pe- duncles, or primary rays, of Daucus carota (Apiaceae). Net microfibril orien[...]
