Forest gene diversity is correlated with the composition and function of soil microbial communities
The growing field of community and ecosystem genetics indicates that plant genotype and genotypic variation are important for structuring communities and ecosystem processes. Little is known, however, regarding the effects of stand gene diversity on soil communities and processes under field conditions. Utilizing natural genetic variation occurring in Populus spp. hybrid zones, we tested the hypothesis that stand gene diversity structures soil microbial communities and influences soil nutrient pools. We found significant unimodal patterns relating gene diversity to soil microbial community composition, microbial exoenzyme activity of a carbonâacquiring enzyme, and availability of soil nitrogen. Multivariate analyses indicate that this pattern is due to the correlation between gene diversity, plant secondary chemistry, and the composition of the microbial community that impacts the availability of soil nitrogen. Together, these data from a natural system indicate that stand gene diversity may affect soil microbial communities and soil processes in ways similar to species diversity (i.e., unimodal patterns). Our results further demonstrate that the effects of plant genetic diversity on other organisms may be mediated by plant functional trait variation.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/147191/1/pope0035.pd

Cholangiography using 64-multi-detector row computed tomography in the normal dog
Hepatobiliary disease can sometimes be difficult to diagnosis due to non-specific clinical signs, and diagnostic imaging is a vital tool in diagnosing these diseases. Multi-slice computed tomographic cholangiography (MSCTC) is a non-invasive way to obtain high quality images of the hepatobiliary system. Our objectives were to determine the best technique for performing MSCTC in normal dogs with regards to contrast agent, dose, and optimal time to imaging. Our test subjects included eight normal adult hounds. Four dogs were administered Cholografin and the other four Biliscopin. Two dose groups were established with four dogs receiving 0.5mL/kg and four receiving 1 mL/kg. Our results demonstrated that MSCTC is feasible in normal dogs and produces high quality images of the hepatobiliary system. The contrast agent Biliscopin at the higher dose subjectively produced the best quality images. The optimal time to image patients following contrast administration varied between contrast agents (15-60 minutes)

Amphiphilic Cross-Linked Liquid Crystalline Fluoropolymer-Poly(ethylene glycol) Coatings for Application in Challenging Conditions: Comparative Study between Different Liquid Crystalline Comonomers and Polymer Architectures
Linear
and hyperbranched polyÂ(ethylene glycol)-cross-linked amphiphilic
fluoropolymer networks comprised of different liquid crystalline comonomers
were developed and evaluated as functional coatings in extreme weather-challenging
conditions. Through variation of the liquid-crystalline comonomer
and hydrophilic:hydrophobic component ratios, several series of coatings
were synthesized and underwent a variety of analyses including differential
scanning calorimetry, water contact angle measurements and solution
stability studies in aqueous media. These materials maintained an
unprecedented reduction in the free water melting transition (<i>T</i><sub>m</sub>) temperature across the hyperbranched and
linear versions. The coatings synthesized from hyperbranched fluoropolymers
preserved the liquid crystalline character of the mesogenic components,
as seen by polarized optical microscopy, and demonstrated stability
in saltwater aqueous environments and in cold weather conditions
