SBC LTER: Beach: Distribution of terrestrial organic material in intertidal and nearshore marine sediment due to debris flow response efforts
These data describe the distribution and processing of terrestrial organic material observed in the Santa Barbara Channel (Goleta Bay) during the spring of 2018. Specifically, beach, slough, and marine sediments were sampled during and after the debris disposal event that took place between January and February 2018 following the Thomas Fire and the subsequent Montecito Debris Flow. Data are contained in one table, including organic carbon, carbon isotope, lignin phenol, and pyrogenic carbon measurements analyzed from sediment cores collected at different depths and locations in the nearshore region.
SBC LTER: Reef: The size-dependent functional response of lobster foraging on purple urchin
These data summarize the results of a size-dependent functional response experiment in which California spiny lobster (Panulirus interruptus) foraged on purple urchins (Strongylocentrotus purpuratus). Lobster of different sizes foraged on one of three different size classes of urchins at 4-6 different densities of urchin. Data is used to support manuscript: DiFiore, B.P. and A.C. Stier. 2023. Variation in body size drives spatial and temporal variation in lobster-urchin interaction strength. Journal of Animal Ecology
Biocrust disturbance experiment soil responses 2016
Biological soil crusts (biocrusts) dominate soil surfaces in drylands, providing services that include soil stabilization and carbon uptake. In this study, we investigated the direct and biocrust-mediated effects of anthropogenic disturbances in two dryland ecosystems. We applied low intensity soil surface disturbance (twice-yearly footfalls) in grassland and shrubland ecosystems in northern Chihuahuan Desert, USA. Results. After five years of disturbance, biocrust photosynthetic capacity (chlorophyll a) declined by 44%. Declines were largest in interspaces between grassland plants. Levels of scytonemin, a biocrust sunscreen pigment, were 38% greater in shrubland than grassland and 44% greater under grass canopy than in interspaces, but decreased only 5% with disturbance. Disturbance reduced soil surface stability 2 times more in the grassland than shrubland. Disturbance effects on other hydrologic and physical properties were indirectly mediated by the photosynthetic capacity of biocrusts. Disturbance indirectly increased infiltration depth and shallow (2-3 cm) soil moisture in the grassland but reduced surface moisture (<1 cm) in the shrubland. Conclusions. Biocrusts were more sensitive to low intensity soil disturbance in a grassland than shrubland ecosystem. While biocrusts mediated the effects of soil disturbance on dryland soil hydrological and physical properties, the nature of their influence differed between ecosystem types.
Coastal SEES Collaborative Research: Coastal Sustainability: A cross-site comparison of salt marsh persistence in response to sea-level rise and feedbacks from social adaptations
Coastal ecosystems are often valued for decision-making purposes based on monetized market and non-market values of goods and services, and associated economic impacts. Examples include values of fishery landings, price changes for waterfront homes, and tourism revenues. Monetized quantities such as these do not provide a comprehensive characterization of the values provided by these ecosystems. Human reliance on the goods and services provided by ecosystems and the global decline in the health of many of these ecosystems suggests the need for ecosystem valuation to help inform decision-making and conservation policy. However, traditionally employed economic valuation methods are rarely able to capture the full scope of the benefits ecosystems provide, including benefits provided by "cultural" ecosystem services. Qualitative methods such as focus groups can provide insight on these values not available through quantitative methods alone. This research explores public perceptions of salt marsh value through the use of semi-structured focus groups in marsh-adjacent communities in Massachusetts, Virginia, and Georgia. The data include de-identified focus group transcripts from three 90-minute focus groups held in each state. Initial questions were drawn from the same semi-structured question list in each focus group, with exploratory follow-up questions based on participant responses. Results of text analysis suggest that in case study communities, outdoor experiences in salt marshes inspire serenity in Massachusetts, influence shore identities in Virginia, and promote stewardship cultivation in Georgia. Perceived threats to these benefits, such as the threat of residential development, industrial pollution, and increasing flood risk, together constitute the context for various community responses related to marsh protection. Results supplement information from extant economic valuations and show the importance of utilizing diverse methods to elicit information on soci
PsPM-trSP4: SCR measurement in response to face photographs withangry, neutral, and fearful expression while subjected to auditory distractors
<p>This dataset includes skin conductance response (SCR) measurements for each of 42 healthy unmedicated participants (21 males and 21 females aged 25.2 +/- 4.0 years) in response to 38 face photographs (modified from the Karolinska Directed Emotional Faces set, KDEF), each presented once with angry, neutral, and fearful expression for 1 s each. Meanwhile, participants were listening to regular or random distractor sounds, as described in Bach et al. (2015). ITI was selected randomly on each trial from 7.5 s, 9.0 s, or 10.5 s (misprinted in the publications), plus a variable delay of around 0.1 s for image loading. The experiment was preceded by a 2-minute resting period and divided into 3 blocks, separated by resting periods. Each resting period begins and ends with an event marker in the SCR recordings.</p>

Response of psychrophilic plant endosymbionts to experimental temperature increase
<p>Countless uncertainties remain regarding the effects of global warming on biodiversity, including the ability of organisms to adapt and how that will affect obligate symbiotic relationships. The present study aimed to determine the consequences of temperature increase on the adaptation of plant endosymbionts (endophytes) that grow better at low temperatures (psychrophilic). We isolated fungal endophytes from a high-elevation (paramo) endemic plant. Initial growth curves were constructed at different temperatures (4–25°C). Then, experiments were carried in which only the psychrophilic isolates were subjected to repeated increments in temperature. After the experiments, the final growth curves showed significantly slower growth than the initial curves, and some isolates even ceased to grow. While most studies suggest that the distribution of microorganisms will expand as temperatures increase because most of these organisms grow better at 25°C, the results from our experiments demonstrate that psychrophilic fungi were negatively affected by temperature increases. These outcomes raise questions concerning the potential adaptation of beneficial endosymbiotic fungi in the already threatened plant ecosystems. Assessing the consequences of global warming at all trophic levels is urgent because many species on Earth depend on their microbial symbionts for survival. Associations are mutually beneficial, results from our study have implications on the potential survival of these plants and high-elevation ecosystems.</p>

PsPM-SSNA_1-2: Sudomotor Nerve Activity and Skin Conductance Response to 1: Aversive Sounds and 2: Auditory Oddballs
<p>This dataset includes skin conductance response (SCR) and sudomotor neurography signals for each of 7 healthy unmedicated participants 4 male, 3 female,23.7+/-4.0 years) in response to 20 broadband white noise sounds (SSNA_1) or 10 oddball tones in a oddball task (SSNA_2). Some participants did not complete SSNA_2 or had several repetitions of SSNA_1 such that there are 9 recordings for SSNA_1 and 5 recordings for SSNA_2. White noise sounds in SSNA_1 were 1 s long with 10 ms on- and offset ramp and presented at ~85 dB. Oddball and standard sounds in SSNA_2 were 50 ms long, with 10 ms on- and offset ramp, and presented at ~75 dB. Sound frequency was 440 Hz or 460 Hz. White noise sounds and oddball tones was separated by a random inter trial interval of at least 30 s. All stimuli for each of the experiments were presented in one block. There is a marker for each sound onset (including standard tones) in the spike recordings. Participants where instructed to press a button when hearing any sound (SSNA_1) or an oddball (SSNA_2). These keystrokes where not recorded.</p>
