How surface rock cover affects water and nutrient availability of Sonoran Desert annual plants -- Honors Thesis
Water and nutrient availability are the primary and secondary drivers of net primary productivity (NPP) in arid ecosystems. Although precipitation regulates water inputs, soil properties influence water availability for plant growth. Aridland soils are often covered with surface rocks, which can increase or decrease water availability by modifying evaporation, infiltration, light levels, and temperature. Due to the complexity of these direct and indirect mechanisms, the relationship between rock cover and NPP is not well understood. In this research we explore the relationship between rock cover, soil nutrient availability, and aboveground growth of desert annual plants over four years across a long-term nutrient enrichment experiment in the Sonoran Desert. We surveyed surface rock cover at fifteen sites in central Arizona that have been fertilized with nitrogen (N) and phosphorus (P), alone and in combination, for seven years. Using ANCOVA, we then explored the relative importance of rock cover, precipitation, and nutrient treatment on peak aboveground biomass of spring herbaceous annual plants that were collected in 2008, 2009, 2010, and 2013. We expected surface rocks to strengthen the positive relationship between precipitation, nutrient additions, and annual plant growth. Precipitation, nutrient additions, and surface rock cover together significantly influence growth of Sonoran Desert annual plants. As expected, nutrients and precipitation were the strongest drivers of annual plant biomass. Plant growth was positively related to N additions across all four years (ANCOVA, p <0.01); P in 2008 and 2010 years (p = 0.01 and 0.005, respectively);and precipitation in three of the four years (p < 0.05). Precipitation was the primary driver of plant biomass in the two driest years, 2009 and 2013 (partial eta2 = 0.51 and 0.52, respectively). Gravel (2-64 mm diameter) was only rock size class that was significantly related to annual plant biomass. Contrary to our expecta
Forest soil acidification consistently reduces litter decomposition irrespective of nutrient availability and litter type
<p><span><span>Nitrogen (N), phosphorus (P), and acid deposition are co-occurring in many ecosystems, likely with complex interactive effects on litter decomposition. </span></span></p> <p><span><span>Few studies have been conducted to distinguish the interactive effects of these three factors on forest litter decomposition. Thus, we performed a 5-year litter decomposition experiment with N, P, acid addition in a temperate forest of Changbai Mountain in China, including four litter types from <i>Pinus koraiensis</i>, <i>Quercus mongolica</i>, <i>Tilia amurensis</i> and their mixtures. </span></span></p> <p><span><span>Our results showed that acid addition consistently reduced litter decomposition rate, irrespective of nutrient addition or litter types. In contrast, N and P addition had less impact on litter decomposition. Litter decomposition rate linearly reduced with decreasing soil pH, but positively increased with soil N availability. No relationship was found between soil P availability and litter decomposition. Soil enzyme activity played a key role in regulating litter decomposition response, such as acid phosphatase, xylosidase, N-cacetyl-b-D-glucosaminidase and α-1,4 glucosidase. Besides, low-quality litter (i.e. high C concentration, C:N and C:P ratio) amplified the negative effect of soil acidification on litter decomposition. </span></span></p> <p><span><span>This study suggests that soil acidification consistently decelerates litter decomposition in temperate forests, which is independent of soil nutrient availability and litter types. The intensifying soil acidification with continuous N deposition in the future will greatly reduce litter nutrient return to soil, increasing the risk of multiple soil nutrient limitation.</span></span></p>
Effect of maternal infection on progeny growth and resistance mediated by maternal genotype and nutrient availability
<div class="_3U2q6dcdZCrTrR_42Nxby JWNdg1hee9_Rz6bIGvG1c allowTextSelection"> <div> <div class="BodyFragment"> <div class="PlainText">1. Maternal effects of pathogen infection on progeny development and disease resistance may be adaptive and have important consequences for population dynamics. However, these effects are often context dependent and examples of adaptive transgenerational responses from perennials are scarce, although they may be a particularly important mechanism generating variation in the offspring of long-lived species.</div> <div class="PlainText"> <br> 2. Here, we studied the effect of maternal infection of Plantago lanceolata by Podosphaera plantaginis, a fungal parasite, on the growth, flower production and resistance of the progeny of six maternal genotypes in nutrient rich and poor environments. For this purpose, we combined a common garden study with automated phenotyping measurements of early life-stages, and an inoculation experiment.</div> <div class="PlainText"> <br> 3. Our results show that the effects of infection on the mother plants transcend to impact their progeny. Although maternal infection decreased total leaf and flower production of the progeny by the end of the growing season, it accelerated early growth and enhanced resistance to the pathogen P. plantaginis.</div> <div class="PlainText"> <br> 4. We also discovered that the effects of maternal infection affected progeny development and resistance both directly, and through a three way-interaction between maternal genotype, maternal infection status and nutrient availability.</div> <div class="PlainText"> </div> <div class="PlainText">5. Synthesis: Our results emphasize the importance of maternal effects mediated through genotypic and environmental factors in long living perennials and suggest that maternal infection can create a layer of phenotypic diversity in resistance. These results may have important implications for both epidemiological and evolutionary dynamics of host–parasite interactions in the wild.</div> </div> </div> </div>
