Mycorrhizal phenotypes and the Law of the Minimum
Mycorrhizal phenotypes arise from interactions among plant and fungal genotypes and the environment. Differences in the stoichiometry and uptake capacity of fungi and plants make arbuscular mycorrhizal (AM) fungi inherently more nitrogen (N) limited and less phosphorus (P) limited than their host plants. Mutualistic phenotypes are most likely in P‐limited systems and commensal or parasitic phenotypes in N‐limited systems. Carbon (C) limitation is expected to cause phenotypes to shift from mutualism to commensalism and even parasitism. Two experiments compared the influence of fertilizer and shade on mycorrhizas in Andropogon gerardii across three naturally N‐limited or P‐limited grasslands. A third experiment examined the interactive effects of N and P enrichment and shade on A. gerardii mycorrhizas. Our experiments generated the full spectrum of mycorrhizal phenotypes. These findings support the hypothesis that mutualism is likely in P‐limited systems and commensalism or parasitism is likely in N‐limited systems. Furthermore, shade decreased C‐assimilation and generated less mutualistic mycorrhizal phenotypes with reduced plant and fungal biomass. Soil fertility is a key controller of mycorrhizal costs and benefits and the Law of the Minimum is a useful predictor of mycorrhizal phenotype. In our experimental grasslands arbuscular mycorrhizas can ameliorate P‐limitation but not N‐limitation.

Resource limitation is a driver of local adaptation in mycorrhizal symbioses
Symbioses may be important mechanisms of plant adaptation to their environment. We conducted a reciprocal inoculation experiment to test the hypothesis that soil fertility is a key driver of local adaptation in arbuscular mycorrhizal (AM) symbioses. Ecotypes of Andropogon gerardii from phosphorus-limited and nitrogen-limited grasslands were grown with all possible \"home and away\" combinations of soils and AM fungal communities. Our results indicate that Andropogon ecotypes adapt to their local soil and indigenous AM fungal communities such that mycorrhizal exchange of the most limiting resource is maximized. Grasses grown in home soil and inoculated with home AM fungi produced more arbuscules (symbiotic exchange structures) in their roots than those grown in away combinations. Also, regardless of the host ecotype, AM fungi produced more extraradical hyphae in their home soil, and locally adapted AM fungi were, therefore, able to sequester more carbon compared with nonlocal fungi. Locally adapted mycorrhizal associations were more mutualistic in the two phosphorus-limited sites and less parasitic at the nitrogen-limited site compared with novel combinations of plants, fungi, and soils. To our knowledge, these findings provide the strongest evidence to date that resource availability generates evolved geographic structure in symbioses among plants and soil organisms. Thus, edaphic origin of AM fungi should be considered when managing for their benefits in agriculture, ecosystem restoration, and soil-carbon sequestration.

Pedagogies for the future : leading quality learning and teaching in higher education
This book illustrates a unique and exciting endeavor whereby a group of academics across one university developed a professional learning community for the purposes of investigating, articulating and developing their scholarship of practice. Through their collaborative efforts, these educator-researchers sit at the forefront of calls to take teaching seriously in higher education and to recognize the powerful potential of interdisciplinary collaboration. The book provides a model for establishing learning communities in higher education and demonstrates that such work is not only possible but also successful. From vision to reality, This book offers important insights into the complex nature of researching teaching and learning in higher education from the perspectives of those directly engaged in it. This book will be of great interest and value to both scholars and administrators.

Changing lives: improving care leaver access to higher education
Australian and international research documents the limited access of young people transitioning from out-of-home care (OOHC) to further and higher education. This paper examines the processes, outcomes, and key findings of the Raising Expectations project, a collaborative university and industry approach to promote higher education among care leavers at two Australian universities. That approach was informed by the co-authors' previous research, including interviews with enrolled care-leaver students. The paper highlights the relevance of that research in the design and implementation of Raising Expectations. Our findings reiterate the importance of policy and practice reforms informed by rigorous research, particularly involving the voices and agency of care leavers. We outline strategies adopted by the participating universities resulting in a fourfold increase in enrolments, growth in school outreach activities, and significantly improved retention rates. The paper also highlights barriers to higher education access and success, through care-leaver student interviews and policy analysis. These interviews revealed the need for better university outreach and information to prospective care-leaver students, improved support for enrolled care-leaver students, and better capturing of data by universities and governments. The paper also highlights policy barriers to the greater expansion of care-leavers at university, especially in the absence of extended state care.

Hetty Feather
It's London, 1876 and Hetty Feather is just a tiny baby when her mother leaves her at the Foundling Hospital. The Hospital cares for abandoned children - but Hetty must first live with a foster family until she is big enough to go to school. Life in the countryside is hard but with her 'brothers' Jem and Gideon, she helps in the fields and plays imaginary games. Together they sneak off to visit the travelling circus and Hetty is mesmerised by the show, especially Madame Adeline and her performing horses. But Hetty's happiness is threatened once more when she is returned to the Foundling Hospital. The new life of awful uniforms and terrible food is a struggle for her. But now she has the chance to find her real mother.

Measuring Indices of Happiness and Their Relation to Challenging Behavior
Behavioral correlates to happiness (i.e., indices of happiness) have been used as means of measuring happiness in individuals with developmental disabilities. However, research has not yet evaluated the possibility that indices of happiness/unhappiness (IHUs) may signal the presence of a setting event that could affect other behaviors. The purpose of this study was to assess the relation between indices of happiness/unhappiness (IHUs) and challenging behavior with a 14-year-old boy diagnosed with autism spectrum disorder. A conditional probability calculation was used to evaluate the relation between IHUs, demand type, and challenging behavior. Results indicated that different IHUs predicted specific topographies of challenging behavior given demands to transition or engage in academic tasks.

Airborne Single Particle Mass Spectrometers (SPLAT II & miniSPLAT) and New Software for Data Visualization and Analysis in a Geo-Spatial Context
Understanding the effect of aerosols on climate requires knowledge of the size and chemical composition of
individual
aerosol particles—two fundamental properties that determine an aerosol’s optical properties and ability to serve as cloud condensation or ice nuclei. Here we present our aircraft-compatible single particle mass spectrometers, SPLAT II and its new, miniaturized version, miniSPLAT that measure in-situ and in real-time the size and chemical composition of individual aerosol particles with extremely high sensitivity, temporal resolution, and sizing precision on the order of a monolayer. Although miniSPLAT’s size, weight, and power consumption are significantly smaller, its performance is on par with SPLAT II. Both instruments operate in dual data acquisition mode to measure, in addition to single particle size and composition, particle number concentrations, size distributions, density, and asphericity with high temporal resolution. We also present ND-Scope, our newly developed interactive visual analytics software package. ND-Scope is designed to explore and visualize the vast amount of complex, multidimensional data acquired by our single particle mass spectrometers, along with other aerosol and cloud characterization instruments on-board aircraft. We demonstrate that ND-Scope makes it possible to visualize the relationships between different observables and to view the data in a geo-spatial context, using the interactive and fully coupled Google Earth and Parallel Coordinates displays. Here we illustrate the utility of ND-Scope to visualize the spatial distribution of atmospheric particles of different compositions, and explore the relationship between individual particle compositions and their activity as cloud condensation nuclei.
