description: The South Central Farm (SCF) in Los Angeles was a 14-acre urban farm in one of the highest concentrations of impoverished residents in the county. It was destroyed in July 2006. This article analyzes its epic as a landscape of resistance to discriminatory legal and planning practices. It then presents its creation and maintenance as an issue of environmental justice, and argues that there was a substantive rationale on the basis of environmental justice and planning ethics that should have provided sufficient grounds for the city to prevent its dismantling. Based on qualitative case study methodology, the study contributes to the formulation of creation and preservation rationales for community gardens and other “commons” threatened by eventual dismantlement in capitalist societies.

description: It is recognised that levels of communication impairment are likely to be higher among looked-after children than they are in the general population (Royal College of Speech and Language Therapists [RCSLT], 2006). Moreover, there are claims that communication needs in this vulnerable population remain largely undetected and unmet (Cross, 2004). Empirical research in this area is lacking.

description: Different solutions have been proposed to solve the "faint young Sun problem", defined by the fact that the Earth was not fully frozen during the Archean despite the fainter Sun. Most previous studies were performed with simple 1-D radiative convective models and did not account well for the clouds and ice-albedo feedback or the atmospheric and oceanic transport of energy. We apply a global climate model (GCM) to test the different solutions to the faint young Sun problem. We explore the effect of greenhouse gases (CO2 and CH4), atmospheric pressure, cloud droplet size, land distribution, and Earth's rotation rate. We show that neglecting organic haze, 100 mbar of CO2 with 2 mbar of CH4 at 3.8 Ga and 10 mbar of CO2 with 2 mbar of CH4 at 2.5 Ga allow a temperate climate (mean surface temperature between 10°C and 20°C). Such amounts of greenhouse gases remain consistent with the geological data. Removing continents produces a warming lower than +4°C. The effect of rotation rate is even more limited. Larger droplets (radii of 17 microns versus 12 microns) and a doubling of the atmospheric pressure produce a similar warming of around +7°C. In our model, ice-free water belts can be maintained up to 25°N/S with less than 1 mbar of CO2 and no methane. An interesting cloud feedback appears above cold oceans, stopping the glaciation. Such a resistance against full glaciation tends to strongly mitigate the faint young Sun problem.

Water interaction with raw, intermediate and final pharmaceutical materials
Creators: name: Liu, Zhanjie
Publisher: name: No Publisher Supplied

description: Tablets is the most convenient way to take medication and 70% of the total medicines are dispensed in the form of tablets. The effectiveness of such dosage form depends on how the drug dissolves in the fluids of the gastrointestinal tract. The dissolution of tablets is dominated by two factors mainly: Wettability of the blends and disintegration of the tablets. The objective of this study consists of: A) Studying the wettability of pharmaceutical blends by droplet penetration method. B) Understanding of the Swelling of pharmaceutical tablets in contact with water. In droplet penetration section, blends of 90% Lactose, 9% APAP, 1% MgSt with varying shear level (0Rev, 160Rev, 640Rev and 1280Rev) were prepared as porous material. To characterize wettability of blends, the penetration profile of both water and silicone oil, which is the volume of droplet versus time, was plotted. The water penetration process consists of three phase: bouncing phase, waiting phase and penetrating phase. By reviewing the penetration model developed by Denesuk, a new method for dynamic contact angle calculation was developed. The results reveal that the wettability of blends decreases as the increasing of shear level. In tablets swelling section, formulations with varying percentage of Avicel and Lactose (80% Avicel-10% Lactose, 45% Avicel-45% Lactose and 10% Avicel-80% Lactose) were used to make tablets with different compaction force ranging from 4KN to 24KN. A experiment was designed to measure the swelling of tablets and mass of water uptake meantime. Both the swelling profile and the water uptake profile of tablets present two behaviors: linear and non-linear, which reveal two possible liquid uptake mechanisms: capillary penetration and particle swelling. Swelling rate and water uptake rate of tablets can be calculated from the swelling profile and water uptake profile. Both of them are non-monotonic with compaction and formulation.

description: Since it is commonly believed that the observed large-scale structure of the Universe is an imprint of quantum fluctuations existing at the very early stage of its evolution, it is reasonable to pose the question: Do the effects of quantum nonlocality, which are well established now by the laboratory studies, manifest themselves also in the early Universe? We try to answer this question by utilizing the results of a few experiments, namely, with the superconducting multi-Josephson-junction loops and the ultracold gases in periodic potentials. Employing a close analogy between the above-mentioned setups and the simplest one-dimensional Friedmann-Robertson-Walker cosmological model, we show that the specific nonlocal correlations revealed in the laboratory studies might be of considerable importance also in treating the strongly-nonequilibrium phase transitions of Higgs fields in the early Universe. Particularly, they should substantially reduce the number of topological defects (e.g., domain walls) expected due to independent establishment of the new phases in the remote spatial regions. This gives us a hint for resolving a long-standing problem of the excessive concentration of topological defects, inconsistent with observational constraints. The same effect may be also relevant to the recent problem of the anomalous behavior of cosmic microwave background fluctuations at large angular scales.

description: Reflection measurements give access to the complex impedance of a material on a wide frequency range. This is of interest to study the dynamical properties of various materials, for instance disordered superconductors. However reflection measurements made at cryogenic temperature suffer from the difficulty to reliably subtract the circuit contribution. Here we report on the design and first tests of a setup able to precisely calibrate in situ the sample reflection, at 4.2 K and up to 2 GHz, by switching and measuring, during the same cool down, the sample and three calibration standards.

description: The unusual features of quantum mechanics are enabling the development of technologies not possible with classical physics. These devices utilize nonclassical phenomena in the states of atoms, ions, and solid-state media as the basis for many prototypes. Here we investigate molecular states as a distinct alternative. We demonstrate a memory for light based on storing photons in the vibrations of hydrogen molecules. The THz-bandwidth molecular memory is used to store 100-fs pulses for durations up to 1ns, enabling 10,000 operational time bins. The results demonstrate the promise of molecules for constructing compact ultrafast quantum photonic technologies.

description: Most U.S. households have consistent, dependable access to enough food for active, healthy living—they are food secure. However, some households experience food insecurity at times during the year, meaning their access to adequate food is limited by a lack of money and other resources. USDA’s food and nutrition assistance programs aim to increase food security by providing low-income households access to food for a healthful diet, as well as nutrition education. USDA monitors the extent and severity of food insecurity in U.S. households through an annual, nationally representative survey sponsored and analyzed by USDA’s Economic Research Service (ERS). This report presents statistics from the survey that cover household food security, food expenditures, and use of Federal nutrition assistance programs in 2021.

description: Cloud Mining technique can be applied to various documents. Acquisition and storage of video data is an easy task but retrieval of information from video data is a challenging task. So video Cloud Mining plays an important role in efficient video data management for information retrieval. This paper proposes a Cellular Automata based framework for video Cloud Mining to extract the information from video data. This includes developing the technique for shot detection then key frame analysis is considered to compare the frames of each shot to each others to define the relationship between shots. Cellular automata based hierarchical clustering technique is adopted to make a group of similar shots to detect the particular event on some requirement as per user demand.

description: Ugi-adducts were obtained via a one-pot four-component reaction of divergent aldehydes, amines, aroylacrylic acids and isocyanide in methanol. These products were subjected to intramolecular Michael addition in the presence of K2CO3 in DMF at room temperature to afford a single product. Literally, the formation of two heterocyclic systems, 6membered diones or 7-membered diones are possible, which could not be identified by conventional spectroscopic methods. The X-ray crystallographical data was obtained for one selected product, which indicated preferential formation of the corresponding 6membered dione. In order to establish the generality of this mode of cyclization, the quantum chemistry calculations were performed. The obtained results confirmed the favorable formation of 6-membered diones in the gas and also several solution phases. All the products were screened for their antibacterial and antifungal activities.

description: The purpose of this study was to investigate the impact of metabolic syndrome (MS) on outcome of catheter ablation (CA) for treatment of frequent premature ventricular contraction beats (PVCs) originating from right ventricular outflow tract (RVOT), left ventricular outflow tract (LVOT) or coronary cusps (CUSPs), in patients with normal ventricular systolic function and absence of cardiac structural disease. In this multicentre prospective study we evaluated 90 patients with frequent PVCs originating from RVOT (n = 68), LVOT (n = 19) or CUSPs (n = 3), treated with CA. According to baseline diagnosis they were divided in patients with MS (n = 24) or without MS (n = 66). The study endpoint was a composite of recurrence of acute or delayed outflow tract ventricular arrhythmia: acute spontaneous or inducible outflow tract ventricular arrhythmia recurrence or recurrence of outflow tract PVCs in holter monitoring at follow up. Patients with MS compared to patients without MS showed a higher acute post-procedural recurrence of outflow tract PVCs (n = 8, 66.6%, vs. n = 6, 9.0%, p = 0.005). At a mean follow up of 35 (17-43) months survival free of recurrence of outflow tract PVCs was lower in patients with baseline MS compared to patients without MS diagnosis (log-rank test, p

description: A flow cytometry assay for the glucose transporter SLC2A3/GLUT3 was developed with a genetically-encoded biosensor for measuring free glucose, FLII12Pglu-700md6 (Addgene #17866). This biosensor consists of the E. Coli glucose/galactose-binding protein MglB sandwiched between ECFP and Citrine-YFP. An increase in glucose concentration (dynamic range 0.05 – 11 mM) results in an increased FRET efficiency that can be observed by an increase in Citrine acceptor emission and a decrease in ECFP donor emission.

description: In order to explain cosmic acceleration without invoking "dark" physics, we consider $f(R)$ modified gravity models, which replace the standard Einstein-Hilbert action in General Relativity with a higher derivative theory. We use data from the WiggleZ Dark Energy survey to probe the formation of structure on large scales which can place tight constraints on these models. We combine the large-scale structure data with measurements of the cosmic microwave background from the Planck surveyor. After parameterising the modification of the action using the Compton wavelength parameter $B_0$, we constrain this parameter using ISiTGR, assuming an initial non-informative log prior probability distribution of this cross-over scale. We find that the addition of the WiggleZ power spectrum provides the tightest constraints to date on $B_0$ by an order of magnitude, giving ${\rm log}_{10}(B_0) < -4.07$ at 95% confidence limit. Finally, we test whether the effect of adding the lensing amplitude $A_{\rm Lens}$ and the sum of the neutrino mass $\sum m_ν$ is able to reconcile current tensions present in these parameters, but find $f(R)$ gravity an inadequate explanation.

description: The aim of this study was to investigate the antibacterial, antifungal, and anti-biofilm activities of the methanolic extract of marine Chlorella vulgaris along with its lipid composition, including carotenoids. The C. vulgaris strain, isolated from the Mediterranean coast of northern Morocco, was identified morphologically and molecularly by partial sequencing of the 18S rRNA gene. The methanolic extract of C. vulgaris demonstrated significant antibacterial activity against both Gram-positive and Gram-negative pathogenic bacteria, with MIC values ranging from 3.12 to 12.5 mg mL−1. The antibiofilm activity of the extract was dose-dependent against Staphylococcus epidermidis and Pseudomonas aeruginosa. The extract demonstrated antifungal activity against four fungal strains. A. brasiliensis was shown to be the most sensitive species, whereas M. hiemalis was the least sensitive one. The identified lipid compounds mainly consisted of polar species e.g. phospholipids and carotenoids including lutein and neoxanthin, whose antimicrobial activity is generally recognised.

Transforming Subjectivities: Service that Expands Learning in Urban Planning

description: In a recent service-learning course we taught at the University of Southern California (USC), our goal was the 'transformation of subjectivity", as students traversed their own paths from students to professionals, learners to doers and coeducators, and from experts to collaborators. Our intent was to minimize the boundaries separating classroom and community. We encouraged students to bridge the gap between disciplines (urban planning, public policy, public management, public administration, and real estate) and sought to help them become collaborative and socially responsible professionals. We also tried to change the role that community partners usually play in service-learning partnership. Many public agencies and nonprofit organizations welcome the assistance of students but do not see themselves as educators. We entered each partnership with the goal of becoming coeducators with them. Students were also made explicitly responsible for coeducating their peers on the different project areas they were working on, as they needed to give updates to the rest of the class throughout the semester and their grades were partially assigned by their peers. The transformation of student identities or subjectivities was a central objective of both the service-learning instructors and providers. It was also a major factor in our methodology. We used student evaluations to assess the value of service-learning experiences, and the evaluations were basically a test of whether the transformation we hoped for actually occurred. We used student journals, interviews with community partners, course evaluations, and other course documents to assess this change. As a result of our experience, we offer practical suggestions to urban planning faculty and others who are interested in developing meaningful, sustainable service-learning partnerships that minimize the boundaries between campus and community, student and professional, learner and educator, expert and collaborator, and academic and practitioner. We suggest a pathway to service-learning experiences that can transform the subjectivities of all those involved.

description: Ion flotation as an efficient method for heavy metal ions removal needs a stoichiometric collector concentration to obtain high ions removal. Collector recycling is necessary to reuse in the process and decrease the collector consumption in the process. In this study, ion flotation of zinc and manganese ions was first performed using graphene oxide (GO) as a collector and sodium dodecyl sulfate (SDS) as a co-collector to obtain high ion removal with low collector consumption. The optimum experimental conditions were determined as a GO concentration of 30 mg/L, SDS concentration of 50 mg/L, pH of 9.5, impeller speed of 800 rpm, and air flow rate of 2 mL/min. The removal percentage of zinc and manganese ions and the water recovery obtained 91.30%, 90.14%, and 13.88%, respectively at the optimum conditions. Then, the recyclability of GO used in the process was evaluated by the desorption process. The recycled GO was reused at the optimum conditions in the process. The removal percentage of zinc and manganese ions and the water recovery obtained 85.20%, 83.12%, and 12.58%, respectively. The results indicated that the GO offered valuable advantages, such as recyclability, low collector consumption, and high adsorption efficiency to remove ions using ion flotation for wastewater treatment effectively.

description: Environmental indicators are increasingly being used in policy and management contexts, yet serious data deficiencies exist for many parameters of interest to environmental decision making. With its global synoptic coverage and the wide range of instruments available, satellite remote sensing has the potential to fill a number of these gaps, yet their potential contribution to indicator development has largely remained untested. In this paper we present results of a pilot effort to develop satellite-derived indicators in three major issue areas: ambient air pollution, coastal eutrophication, and biomass burning. A primary focus is on the vetting of indicators by an advisory group composed of remote sensing scientists and policy makers.

description: Alcohol and marijuana are among the most commonly used drugs by adolescents and young adults. The question of whether these two drugs are substitutes or complements has important implications for public policy and prevention strategies, especially as laws regarding the use of marijuana are rapidly changing. Data were drawn from fatally injured drivers aged 16 to 25 who died within 1 h of the crash in nine states with high rates of toxicology testing based from 1999 to 2011 on the Fatality Analysis Reporting System (N = 7,191). Drug tests were performed using chromatography and radioimmunoassay techniques based on blood and/or urine specimens. Relative risk regression and Joinpoint permutation analysis were used. Overall, 50.5% of the drivers studied tested positive for alcohol or marijuana. Univariable relative risk modeling revealed that reaching the minimum legal drinking age was associated with a 14% increased risk of alcohol use (RR = 1.14, 95% CI: 1.02 to 1.28), a 24% decreased risk of marijuana use (RR = 0.76, 95% CI: 0.53 to 1.10), and a 22% increased risk of alcohol plus marijuana use (RR=1.22, 95% CI: 0.90 to 1.66). Joinpoint permutation analysis indicated that the prevalence of alcohol use by age is best described by two slopes, with a change at age 21. There was limited evidence for a change at age 21 for marijuana use. These results suggest that among adolescents and young adults, increases in alcohol availability after reaching the MLDA have marginal effect on marijuana use.

description: Reading is known to be a highly complex, emotion-inducing process, usually involving connected and cohesive sequences of sentences and paragraphs. However, most empirical results, especially from studies using eye tracking, are either restricted to simple linguistic materials (e.g., isolated words, single sentences) or disregard valence-driven effects. The present study addressed the need for ecologically valid stimuli by examining the emotion potential of and reading behavior in emotional vignettes, often used in applied psychological contexts and discourse comprehension. To allow for a cross-domain comparison in the area of emotion induction, negatively and positively valenced vignettes were constructed based on pre-selected emotional pictures from the Nencki Affective Picture System (NAPS; Marchewka et al., 2014). We collected ratings of perceived valence and arousal for both material groups and recorded eye movements of 42 participants during reading and picture viewing. Linear mixed-effects models were performed to analyze effects of valence (i.e., valence category, valence rating) and stimulus domain (i.e., textual, pictorial) on ratings of perceived valence and arousal, eye movements in reading, and eye movements in picture viewing. Results supported the success of the experimental manipulation: emotionally positive stimuli (i.e., vignettes, pictures) were perceived more positively and less arousing than emotionally negative ones. The cross-domain comparison indicated that vignettes are able to induce stronger valence effects than their pictorial counterparts, no differences between vignettes and pictures regarding effects on perceived arousal were found. Analyses of eye movements in reading replicated results from experiments using isolated words and sentences: perceived positive text valence attracted shorter reading times than perceived negative valence at both the supralexical and lexical level. In line with previous findings, no emotion effects on eye movements in picture viewing were found. This is the first eye tracking study reporting superior valence effects for vignettes compared to pictures and valence-specific effects on eye movements in reading at the supralexical level.

description: We report on a comparison between 21 cm rotation measure (RM) and the optically-thin atomic hydrogen column density (N_HI) measured towards unresolved extragalactic sources in the Galactic plane of the northern sky. HI column densities integrated to the Galactic edge are measured immediately surrounding each of nearly 2000 sources in 1-arcminute 21 cm line data, and are compared to RMs observed from polarized emission of each source. RM data are binned in column-density bins 4x10^20 cm^-2 wide, and one observes a strong relationship between the number of hydrogen atoms in a 1 cm^2 column through the plane and the mean RM along the same line-of-sight and path length. The relationship is linear over one order of magnitude (from 0.8-14x10^21 atoms cm^-2) of column densities, with a constant RM/N_HI -23.2+/-2.3 rad m^-2/10^21 atoms cm^-2, and a positive RM of 45.0+/-13.8 rad m^-2 in the presence of no atomic hydrogen. This slope is used to calculate a mean volume-averaged magnetic field in the 2nd quadrant of ~1.0+/-0.1 micro-Gauss directed away from the Sun, assuming an ionization fraction of 8% (consistent with the WNM). The remarkable consistency between this field and =1.2 micro-Gauss found with the same RM sources and a Galactic model of dispersion measures suggests that electrons in the partially ionized WNM are mainly responsible for pulsar dispersion measures, and thus the partially-ionized WNM is the dominant form of the magneto-ionic interstellar medium.

description: Previous studies have indicated that early life adversity, genetic factors and alcohol dependence are associated with reduced brain volume in adolescents. However, data on the interactive effects of early life adversity, genetic factors (e.g. p.Met66 allele of BDNF), and alcohol dependence, on brain structure in adolescents is limited. We examined whether the BDNF p.Val66Met polymorphism interacts with childhood trauma to predict alterations in brain volume in adolescents with alcohol use disorders (AUDs). We examined 160 participants (80 adolescents with DSM-IV AUD and 80 age- and gender-matched controls) who were assessed for trauma using the Childhood Trauma Questionnaire (CTQ). Magnetic resonance images were acquired for a subset of the cohort (58 AUD and 58 controls) and volumes of global and regional structures were estimated using voxel-based morphometry (VBM). Samples were genotyped for the p.Val66Met polymorphism using the TaqMan® Assay. Analysis of covariance (ANCOVA) and post-hoc t-tests were conducted using SPM8 VBM. No significant associations, corrected for multiple comparisons, were found between the BDNF p.Val66Met polymorphism, brain volumes and AUD in adolescents with childhood trauma. These preliminary findings suggest that the BDNF p.Met66 allele and childhood trauma may not be associated with reduced structural volumes in AUD. Other genetic contributors should be investigated in future studies.

description: The Remote Associates Test (RAT, CRA) is a classical creativity test used to measure creativity as a function of associative ability. The RAT has been administered in different languages. Nonetheless, because of how embedded in the language the test is, only a few items are directly translatable, and most of the time the RAT is created anew in each language. This process of manual (and in two cases computational) creation of RAT items is guided by the researchers’ understanding of the task. However, are the RAT items in different languages comparable? In this paper, different RAT stimuli datasets are analyzed qualitatively and quantitatively. Significant differences are observed between certain datasets in terms of solver performance. The potential sources of these differences are discussed, together with what this means for creativity psychometrics and computational vs. manual creation of stimuli.

description: The potential for altered ecosystems and extreme weather events in the context of climate change has raised questions concerning the role that migration plays in either increasing or reducing risks to society. Using modeled data on net migration over three decades from 1970 to 2000, we identify sensitive ecosystems and regions at high risk of climate hazards that have seen high levels of net in-migration and out-migration over the time period. This paper provides a literature review on migration related to ecosystems, briefly describes the methodology used to develop the estimates of net migration, then uses those data to describe the patterns of net migration for various ecosystems and high risk regions. The study finds that negative net migration generally occurs over large areas, reflecting its largely rural character, whereas areas of positive net migration are typically smaller, reflecting its largely urban character. The countries with largest population such as China and India tend to drive global results for all the ecosystems found in those countries. Results suggest that from 1970 to 2000, migrants in developing countries have tended to move out of marginal dryland and mountain ecosystems and out of drought-prone areas, and have moved towards coastal ecosystems and areas that are prone to floods and cyclones. For North America results are reversed for dryland and mountain ecosystems, which saw large net influxes of population in the period of record. Uncertainties and potential sources of error in these estimates are addressed.
Ethnomusicology as Interdisciplinary Musicology: A Case Study
Creators: name: Williams, Sean
Publisher: name: Columbia University
Year: 1998
Subjects: Music

description: Ethnomusicologists belong to an inherently interdisciplinary musicology. We often come to graduate work in the field with undergraduate training in Western music and anthropology, and take graduate courses in politics, religion, cultural studies, multicultural literature, and related fields. Like our colleagues in musicology, we learn several languages (at least one local language and often a national or colonial language as well as French and/or German). After graduating with Ph.D.s in ethnomusicology and beginning careers as assistant professors, we are generally expected to teach four or five courses a year, including a Western "classical" music survey course and very often a world music survey course'! Of course, this graduate school track does not apply to all of us, but surely to many. When the moment comes to present survey course material to our students, however, we tend to back away from that interdisciplinary approach in favor of covering as many areas, genres, and musical terms as possible. Greater coverage may be the norm either because it was ordered from the college administration or simply because it reflects the way many of us received survey courses as undergraduates. This article uses the case study of interdisciplinary work in music at The Evergreen State College as a potential pathway to greater depth of understanding at an undergraduate level than one might otherwise achieve.

description: Assume that a block operator of the form $\left(\begin{smallmatrix}A_{1}\\A_{2}\quad 0\end{smallmatrix}\right)$, acting on the Banach space $X_{1}\times X_{2}$, generates a contraction $C_{0}$-semigroup. We show that the operator $A_{S}$ defined by $A_{S}x=A_{1}\left(\begin{smallmatrix}x\\SA_{2}x\end{smallmatrix}\right)$ with the natural domain generates a contraction semigroup on $X_{1}$. Here, $S$ is a boundedly invertible operator for which $ε\ide-S^{-1}$ is dissipative for some $ε>0$. With this result the existence and uniqueness of solutions of the heat equation can be derived from the wave equation.

description: The Gemini Planet Imager (GPI) is currently in its final Acceptance & Testing stages. GPI is an XAO system based on a tweeter & woofer architecture (43 & 9 actuators respectively across the pupil), with the tweeter being a Boston Michromachines $64^2$ MEMS device. The XAO AO system is tightly integrated with a Lyot apodizing coronagraph. Acceptance testing started in February 2013 at the University of California, Santa Cruz. A conclusive acceptance review was held in July 2013 and the instrument was found ready for shipment to the Gemini South telescope on Cerro Pachon, Chile. Commissioning at the telescope will take place by the end of 2013, matching the summer window of the southern hemisphere. According to current estimates the 3 year planet finding campaign (890 allocated hours) might discover, image, and spectroscopically analyze 20 to 40 new exo-planets. Final acceptance testing of the integrated instrument can always bring up surprises when using cold chamber and flexure rig installations. The latest developments are reported. Also, we will give an overview of GPI's lab performance, the interplay between subsystems such as the calibration unit (CAL) with the AO bench. We report on-going optimizations on the AO controller loop to filter vibrations and last but not least achieved contrast performance applying speckle nulling. Furthermore, we will give an outlook of possible but challenging future upgrades as the implementation of a predictive controller or exchanging the conventional 48x48 SH WFS with a pyramid. With the ELT era arising, GPI will proof as a versatile and path-finding testbed for AO technologies on the next generation of ground-based telescopes.

description: As a consequence of ongoing climate change, the frequency of extreme heat events is expected to increase. Recurring heat pulses may disrupt functions supported by soil microorganisms, thus affecting the entire ecosystem. However, most perturbation experiments only test effects of single heat events, and therefore it remains largely unknown how soil microorganisms react to repeated pulse events. Here we present data from a lab experiment exposing 32 filamentous fungi, originally isolated from the same soil, to sequential heat perturbations. Soil saprobic fungi isolates were exposed to one or two heat pulses: mild (35oC/2h), strong (45oC/1h), or both in sequence (35oC/2h+45oC/1h), and we assessed growth rate. Out of the 32 isolates 13 isolates showed an antagonistic response, 3 isolates a synergistic response and 16 isolates responded in an additive manner. Thus the 32 filamentous fungal isolates used here showed the full range of possible responses to an identical heat perturbation sequence. This diversity of responses could have consequences for soil-borne ecosystem services, highlighting the potential importance of fungal biodiversity in maintaining such services, particularly in the context of climate change.
