Litter and root traits control soil microbial composition and enzyme activities in 28 common subtropical tree species
<p><span>1. </span><span>Plant trait-based approaches are frequently used to explore the linkages between aboveground plant communities and belowground ecosystem functions. However, the role of plant leaf litter and living root traits in driving soil microbial biomass, community composition, and enzyme activities has rarely been explored.</span></p> <p><span>2. </span><span>Here, we measured the soil microbial biomass, community composition and enzyme activities related to carbon (C), nitrogen (N), and phosphorus (P) acquisition under three-year-old monocultures of 28 common subtropical tree species in China.</span></p> <p><span>3. </span><span>We found that plant leaf litter and absorptive root traits, including leaf litter C content, litter water holding capacity, and root N content, were the three best predictors for soil microbial biomass and enzyme activities. In particular, resource-exploitative tree species with higher root N contents were associated with microbial communities with lower fungi to bacteria ratios and lower C- and P-acquisition enzyme activities. Tree species with higher leaf litter water holding capacity were associated with microbial resource acquisition strategies for C and P acquisition.</span></p> <p><span>4. </span><span>Synthesis: Our findings highlighted that plant leaf litter and root traits are important for mechanistically understanding the ecological linkage between the plant community and ecosystem functions.</span></p>
Experimental evidence that host species composition alters host-pathogen dynamics in a ranavirus-amphibian assemblage
<p>Losses in biodiversity can alter disease risk through changes in host species composition. Host species vary in pathogen susceptibility and competence. Yet how changes in diversity alter host-pathogen dynamics remains unclear in many systems, particularly with respect to generalist pathogens. Amphibians are experiencing worldwide population declines linked to generalist pathogens, such as ranavirus, and thus represent an ideal group to investigate how host species composition affects disease risk. We conducted experiments where individuals in the laboratory and assemblages of three amphibian species (Pacific tree frogs, Pseudacris regilla; Cascades frogs, Rana cascadae; and Western toads, Anaxyrus boreas) or just A. boreas alone in outdoor mesocosms were exposed to ranavirus as larvae. In laboratory experiment, we observed low survival and high viral loads in P. regilla compared to the other species suggesting that this species was highly susceptible to the pathogen. In the mesocosm experiment, we observed 41% A. boreas mortality when alone and 98% mortality when maintained with P. regilla and R. cascadae. Our results suggest that the presence of highly susceptible species can alter disease dynamics across multiple species, potentially increasing infection risk and mortality in co-occurring species.</p>

Composite Tool Section XCB-105-3612
Sea Mammal Bone, Composite Tool Section. XCB-105-3612. 400 BCE-100 CE XCB-105 Adamagan (Aleut for place of walrus hunters) is at the head of Morzhovoi Bay, western Alaska Peninsula. It is a massive village with multiple occupations. When it was occupied 400 BCE-100 CE, it was the largest village in the Arctic with an estimated 1000 people. It also has limited occupations dated 2200-1700 BCE, 1000-600 BCE, and 900-1100 CE. The Western Alaska Peninsula artifacts are presented as a result of the research conducted under grants NSF 9630072, NSF 9814086, NSF 9996372, NSF 9996415, NSF 1139266, NSF 1321411. H. Maschner, Principal Investigator. These artifacts were scanned with either a Faro Edge Arm or a Minolta Vivid 9i. Processed in Geomagic or Polyworks. 2-8 photos were used for texture in Geomagic Wrap. Original digitizing work done at the IVL at Id. St. Univ.
