Habitat and Scale Shape the Demographic Fate of the Keystone Sea Urchin in Mediterranean Macrophyte Communities
(2012)
Demographic processes exert different degrees of control as individuals grow, and in species that span several habitats and spatial scales, this can influence our ability to predict their population at a particular ...
Prey Responses to Predator Chemical Cues: Disentangling the Importance of the Number and Biomass of Prey Consumed
(2012)
To effectively balance investment in predator defenses versus other traits, organisms must accurately assess predation risk. Chemical cues caused by predation events are indicators of risk for prey in a wide variety of ...
Millipede Taxonomy after 250 Years: Classification and Taxonomic Practices in a Mega-Diverse yet Understudied Arthropod Group
(2012)
Background
The arthropod class Diplopoda is a mega-diverse group comprising >12,000 described millipede species. The history of taxonomic research within the group is tumultuous and, consequently, has yielded a questionable ...
Digits Lost or Gained? Evidence for Pedal Evolution in the Dwarf Salamander Complex ( Plethodontidae)
(2012)
Change in digit number, particularly digit loss, has occurred repeatedly over the evolutionary history of tetrapods. Although digit loss has been documented among distantly related species of salamanders, it is relatively ...
MicroRNA Expression Analysis in the Cellulosic Biofuel Crop Switchgrass () under Abiotic Stress
(2012)
Switchgrass has increasingly been recognized as a dedicated biofuel crop for its broad adaptation to marginal lands and high biomass. However, little is known about the basic biology and the regulatory mechanisms of gene ...
Algal genes in aplastidic eukaryotes are not necessarily derived from historical plastids
(2012-07)
In photosynthetic eukaryotes, many genes were transferred from plastids or algal endosymbionts to nuclear genomes of host cells. These transferred genes are often considered genetic footprints of plastids. However, genes ...
Effects of Aluminum Oxide Nanoparticles on the Growth, Development, and microRNA Expression of Tobacco ()
(2012)
Nanoparticles are a class of newly emerging environmental pollutions. To date, few experiments have been conducted to investigate the effect nanoparticles may have on plant growth and development. It is important to study ...
Selection of Reliable Reference Genes in for Analysis of Nanotoxicity
(2012)
Despite rapid development and application of a wide range of manufactured metal oxide nanoparticles (NPs), the understanding of potential risks of using NPs is less completed, especially at the molecular level. The nematode ...
S.O.S.
(2012-12)
The concept that type 2 diabetes mellitus (T2DM) can be reversed with an intestinal operation is counterintuitive. How could our costliest disease be forced into full, durable, and safe remission with the bypass of a few ...
