title: Environmental niche overlap in sibling planktonic species calanus finmarchicus and c. glacialis in Arctic fjords

description: Knowledge of the environmental preferences of the key planktonic species,
 such as Calanus copepods in the Arctic, is crucial to understand ecosystem
 function and its future under climate change. Here we assessed the
 environmental conditions influencing the development stages of Atlantic C.
 finmarchicus and Arctic C. glacialis, and quantified the extent to which
 their niches overlap by incorporating multiple environmental data. We
 based our analysis on a three-year seasonal collection of zooplankton by
 sediment traps, located on moorings in two contrasting Svalbard fjords:
 the Arctic Rijpfjorden, and the Atlantic-influenced Kongsfjorden. Despite
 large differences in water temperature between the fjords, local realized
 niches of the sibling Calanus species overlapped almost perfectly. The
 exception was the earliest copepodites of C. glacialis in Rijpfjorden,
 which probably utilized the local ice algal bloom in spring. However,
 during periods with no sea ice, like in Kongsfjorden, the siblings of both
 Calanus species showed high synchronization in the population structure.
 Interestingly, differences in temperature preferences of C. finmarchicus
 and C. glacialis were much higher between the studied fjords than between
 the species. Our analysis confirmed the high plasticity of Calanus
 copepods and their abilities to adapt to highly variable environmental
 settings, not only on an interannual basis, but also in a climate warming
 context, indicating some resilience in the Calanus community.

title: Data from: Texas field crickets (Gryllus texensis) use visual cues to place learn but perform poorly when intra- and extra-maze cues conflict

description: Central place foraging field crickets are an ideal system for studying the
 adaptive value of learning and memory, but more research is needed on
 ecology-relevant cognition in these invertebrates. Here, we test the
 visuospatial place learning of Texas field crickets (Gryllus texensis) in
 a radial arm maze. Our study expands previous work on G. texensis
 cognition for accuracy measures and extends our previous findings on
 females to both sexes. Additionally, our study examines whether crickets
 use intra- or extra-maze cues to locate a food reward using a maze
 rotation putting the cues in conflict. We found that male and female
 crickets improved performance over trials when measured by accuracy
 variables but not latency variables; thigmotaxis negatively impacted
 performance in both sexes. In a reward-absent trial, both male and female
 crickets demonstrated place memory. When intra- and extra-maze cues
 conflicted during a rotation trial, crickets’ performance was not better
 than chance. Our rotation results suggest that crickets may experience
 reciprocal overshadowing of conflicting cues – a result most often seen in
 other taxa with conflicting multi-modal cues. We conclude that crickets do
 not rely solely on: (1) a single-cue association; (2) route-following; or
 (3) their own scent cues to navigate the maze. Instead, male and female
 Texas field crickets seem to learn the location of the reward using a
 combination of proximal and distal cues. The possibility to test large
 numbers of wild-caught or laboratory-reared individuals opens the door to
 future investigations on the evolutionary ecology of visuospatial learning
 in these invertebrates.

title: Data for a preliminary molecular phylogeny of the family Hydroptilidae (Trichoptera): exploring the combination of targeted enrichment data and legacy Sanger sequence data

description: The purpose of this study is to provide a proof-of-concept that the use of
 molecular data, particularly targeted enrichment data, and statistically
 supported methods of analysis can result in the construction of a stable
 phylogenetic framework for the microcaddisflies (Trichoptera:
 Hydroptilidae). Here, we use a combination of targeted enrichment data for
 ca. 300 nuclear protein-coding genes and legacy (Sanger-based) sequence
 data for the mitochondrial COI gene and partial sequence from the 28S rRNA
 gene.

title: Estimating Mountain Lion Habitat Connectivity to Guide Wildlife Conservation at The Nature Conservancy’s Jack and Laura Dangermond Preserve; University of California Santa Barbara; 2021-2022.

description: This submission is from a master's group thesis project at The Bren
 School of Environmental Science & Management at the University of
 California, Santa Barbara, and contains the final written report and
 associated datasets. The graduate student researchers who completed this
 project include: Meghan Fletcher, Alyssa Kibbe, Grace Kumaishi, Anna
 Talken, and Nikole Vannest.   The California landscape has been
 fragmented by urban development, infrastructure, and agriculture.
 Maintaining connectivity between areas of wildlife habitat is important
 for the viability of many long-ranging species, such as the mountain lion
 (Puma concolor). Mountain lion populations are highly susceptible to
 habitat fragmentation, and face reduced access to resources and decreased
 genetic diversity. This study explores the habitat connectivity between
 the Jack and Laura Dangermond Preserve (JLDP), a 24,460 acre protected
 property owned by The Nature Conservancy (TNC), and neighboring protected
 areas to identify potential pathways of movement for mountain lions along
 the Central and Southern California coast. In this project, we: 1)
 determine regional connectivity and least cost paths between core habitats
 by modeling suitable mountain lion habitat, 2) estimate mountain lion
 habitat use and movement on JLDP by performing a site-level suitability
 and corridor analysis and 3) create a short film focused on highlighting
 our research, the role that JLDP plays in conservation, and the importance
 of habitat connectivity. The results of our project show that JLDP
 contains suitable habitat for mountain lions and may play a positive role
 in coastal connectivity. When considering the connectivity between JLDP
 and other regional protected areas, our analyses indicate that urbanized
 coastal regions act as barriers to mountain lions and contain pinch points
 that channelize movement. These results can guide TNC in developing
 management strategies for protecting mountain lions on JLDP and in the
 surrounding region.   Analyses were conducted using ArcGIS,
 Google Earth Engine, MaxENT, Circuitscape, and Omniscape. The project
 began in April 2021 and ended in June 2022.

 Earth Engine and Esri ArcOnline from the following sources: NASA, USGS,
 JPL-CalTech, Conservation Science Partners, CalFish, US Census and
 CalFire. It was processed using Esri ArcMap, ArcGIS Pro, Maxent, Omniscape

title: Dataset for: Water, environment, and socioeconomic justice in California: A multi-benefit cropland repurposing framework

description: Low-income, rural frontline communities of California’s Central Valley
 experience environmental and socioeconomic injustice, water insecurity,
 extremely poor air quality, and lack of fundamental infrastructure
 (sewage, green areas, health services), which makes them less resilient.
 Many communities depend financially on agriculture, while water scarcity
 and associated policy may trigger farmland retirement, further hindering
 socioeconomic opportunities. Here we propose a multi-benefit framework to
 repurpose cropland in buffers inside and around (400-m and 1600-m buffers)
 154 rural disadvantaged communities of the Central Valley to promote
 socioeconomic opportunities, environmental benefits, and business
 diversification. We estimated the potential for (1) reductions in water
 and pesticide use, nitrogen leaching, and nitrogen gas emissions, (2)
 managed aquifer recharge, and (3) economic and employment impacts
 associated with clean industries and solar energy. Retiring cropland
 within 1600-m buffers resulted in estimated reductions in annual water use
 of 2.18 km3/year, nitrate leaching into local aquifers of
 105,500 t/year, greenhouse gas emissions of
 2,232,000 t CO2‑equivalent/year, and 5,388 t
 pesticides/year, with accompanying losses in agricultural revenue of
 US$4,213 million/year and employment of 25,682 positions. Buffer
 repurposing investments of US$27 million/year per community for ten years
 showed potential to generate US$101 million/year per community (total
 US$15,578 million/year) for 30 years and 407 new jobs/year (total 62,697
 jobs/year) paying 67% more than prior farmworker jobs. In the San Joaquin
 Valley (southern Central Valley), where groundwater overdraft averages
 2.3 km3/year, potential water use reduction is 1.8 km3/year. We
 identified 99 communities with surficial soils adequate for aquifer
 recharge and canals/rivers within 1600 m. This demonstrates the potential
 of managed aquifer recharge in buffered zones to substantially reduce
 overdraft. The buffers framework shows that well-planned land repurposing
 near disadvantaged communities can create multiple benefits for
 agriculture and industry stakeholders, while improving quality of life in
 disadvantaged communities and producing positive externalities for
 society.

title: Data for: Separation of oil vapor by polyether block amide composite membrane modified with porous materials

description: The ability of membranes to separate oil vapor is affected by
 their permeance and selectivity. This study modifies polyether block amide
 (PEBA) composite membranes with a microporous zeolite, Silicalite-1, or a
 mesoporous zeolite, MCM-41. The results show that when PEBA composite
 membranes are modified with these zeolites, the selective layer of the
 composite membrane is coated more thinly, resulting in a higher flux of
 organic gas. Silicalite-1 increases the hydrophobicity of the membrane,
 which facilitates the adsorption of organic vapor on the membrane
 surface, thus improving the membrane selectivity. In the separation of oil
 vapor, both modified membranes can effectively increase the gas
 permeabilities and selectivities. The main mechanism governing gas
 transport in the MCM-41-modified membrane is Knudsen diffusion, so the
 selectivity for small molecules is improved more significantly. By
 contrast, the dissolution–diffusion mechanism is dominant in the
 Silicalite-1-modified membranes, which considerably increases the
 selectivity for large molecules.

title: Real-world heavy-duty truck trajectories on signalized corridors

description: This dataset contains real-world trajectories of a heavy-duty truck
 traveling on two urban freight corridors—Alameda St and Wilmington
 Ave—near the Ports of Los Angeles and Long Beach in California. Some of
 the signalized intersections on these two corridors have been instrumented
 with communication devices to enable a connected vehicle application
 called Eco-Approach and Departure (EAD). The EAD application uses signal
 phase and timing information from the upcoming traffic signal along with
 the information about the state of the host vehicle and preceding traffic
 to determine the best course of action for the host vehicle to pass
 through the intersection. The truck trajectories in this dataset were
 collected during the real-world experiment to evaluate the effectiveness
 of a truck EAD system in reducing energy consumption of the truck. The
 dataset contains truck trajectories when driving with and without the use
 of the truck EAD system in both directions of the two corridors.
description: Both real-world baseline and eco-drive data files are in .csv
 format. The contents of each file include vehicle speed (in mph), fuel
 rate (in liters/s), and distance to the next intersection (in meters)
 collected every second (1Hz).

title: Islands Within Islands: Bacterial Phylogenetic Structure and Consortia in Hawaiian Lava Caves and Fumaroles

description: Lava caves, tubes, and fumaroles in Hawai‘i present a range of volcanic,
 oligotrophic environments from different lava flows and host unexpectedly
 high levels of bacterial diversity. These features provide an opportunity
 to study the ecological drivers that structure bacterial community
 diversity and assemblies in volcanic ecosystems and compare the older,
 more stable environments of lava tubes, to the more variable and extreme
 conditions of younger, geothermally active caves and fumaroles. Using 16S
 rRNA amplicon-based sequencing methods, we investigated the phylogenetic
 distinctness and diversity and identified microbial interactions and
 consortia through co-occurrence networks in 70 samples from lava tubes,
 geothermal lava caves, and fumaroles on the island of Hawai‘i. Our data
 illustrate that lava caves and geothermal sites harbor unique microbial
 communities, with very little overlap between caves or sites. We also
 found that older lava tubes (500–800 yrs old) hosted greater phylogenetic
 diversity (Faith's PD) than sites that were either geothermally
 active or younger (&lt;400 yrs old). Geothermally active sites had
 a greater number of interactions and complexity than lava tubes. Average
 phylogenetic distinctness, a measure of the phylogenetic relatedness of a
 community, was higher than would be expected if communities were
 structured at random. This suggests that bacterial communities of Hawaiian
 volcanic environments are phylogenetically over-dispersed and that
 competitive exclusion is the main driver in structuring these communities.
 This was supported by network analyses that found that taxa (Class level)
 co-occurred with more distantly related organisms than close relatives,
 particularly in geothermal sites. Network “hubs” (taxa of potentially
 higher ecological importance) were not the most abundant taxa in either
 geothermal sites or lava tubes and were identified as unknown families or
 genera of the phyla, Chloroflexi and Acidobacteria. These results
 highlight the need for further study on the ecological role of microbes in
 caves through targeted culturing methods, metagenomics, and long-read
 sequence technologies.

title: The role of tetradecane in the identification of host plants by the pest bugs Apolygus lucorum and Adelphocoris suturalis

description: Apolygus lucorum and Adelphocoris suturalis are considered serious pests
 to many cultures in China. Safe alternatives are needed to manage these
 mirid pests. The current study identified compounds
 from  volatiles of the ethanol extracts of Phaseolus
 vulgaris pods and the other 10 common hosts. GCMS
 detection showed that tetradecane, 2-propyl-1-pentanol, and dodecanal were
 included in these volatiles and   tetradecane
 was present in all the volatiles.
description: About 10 mL of any given
 extract was added to a glass jar (35 × 20 cm – height and diameter)
 provided with an airflow inlet and outletat the top. An adsorption column
 was attached to the outlet, while activated carbon filter (air flow rate:
 600 L/min) was attached to the inlet. After collecting for 8 h, the
 adsorption column was eluted with chromatographically-pure hexane for
 GC-MS detection of samples. Gas chromatograph settings included an Rtx-5 MS
 chromatographic column (30 m. 0.25 mm; 0.25 µm), injector temperature set
 to 250°C, the carrier gas was helium, and injections were made on
 splitless mode. The oven temperature program was set to three steps: (i)
 40°C for 1 min; (ii) increased to 130°C at the rate of 4°C/min,
 maintaining for 5 min; (iii) increased to 250°C at the rate of 10°C/min
 and maintaining for 5 min. Mass spectrometer has its ion source
 temperature set to 250°C, and scanning speed at 2500, with a 0.3 s
 interval. Mass spectra were compared with standards in the
 Labsolution software to predict the chemical structure of the main
 volatiles in P. vulgaris pods extracts.

title: Do prey recognise the varying risk of lion predation?

description: Predators can induce behavioural changes in prey that influence vigilance,
 grouping patterns and space use, and these can ultimately affect prey
 demography and trophic interactions. Consequently, prey must respond to
 the risk of predation, but little is known about the features that drive
 the spatial responses of prey species to predators. We tested whether prey
 rely more heavily on olfaction or vision in determining their proximity to
 lions reintroduced to Addo Elephant National Park, South Africa. We also
 tested whether prey that are preferentially killed by lions show greater
 responsiveness than those that are not, and whether prey respond to
 predator behavioural states and hunger. Over 1588 observations of
 potential prey locations in relation to lions under varying wind
 directions, lion behaviours and hunger states throughout the day and
 night, we found that vision is the primary determinant of risk avoidance
 with no evidence of wind-driven odour responses affecting prey proximity.
 Prey outside the preferred prey weight range of lions occurred closer to
 lions than those species most at risk of lion predation. Prey were more
 likely to be closer to covertly behaving lions and further from stationary
 lions. Our evidence suggests prey responses to predators in intact,
 multi-species assemblages are context dependent, but driven largely by
 vision.

title: The importance of considering the duration of extreme temperatures when investigating responses to climate change

description: The frequency and duration of heatwaves are increasing because of human
 activities. To cope with the changes, species with longer generation times
 may have to rely on plastic responses. The probability that their
 responses are adaptive is higher if the species have experienced
 temperature fluctuations also in their evolutionary past. However,
 experimental studies investigating responses to heatwaves often use
 exposure times that are significantly shorter than recent heatwaves. We
 show that this can lead to faulty conclusions and that the duration of
 higher temperature has to be considered in experimental designs. We
 recorded the response of threespine stickleback to prolonged duration of
 higher temperature during the breeding season, using a population that has
 experienced large fluctuations in temperature in its past and, hence, is
 expected to endure temperature changes well. We found males to adaptively
 adjust their reproductive behaviours to short periods of higher
 temperature, but not to longer periods that extended across two breeding
 cycles. Males initially increased their reproductive activities - nest
 building, courtship and parental care - which ensured high reproductive
 success during the first breeding cycle, but decreased their reproductive
 activities during the second breeding cycle when exposed to sustained high
 temperature. This reduced their courtship success and resulted in fewer
 offspring. Thus, a species expected to cope well with higher temperature
 suffers fitness reductions when the duration of high temperature is
 prolonged. The results stress the importance of considering the duration
 of extreme environmental conditions when investigating the impact that
 human activities have on species. Responses to short-term exposures cannot
 be extrapolated to assess responses to longer periods of extreme
 conditions.

title: Can fire-age mosaics really deal with conflicting needs of species? A study using population hotspots of multiple threatened birds

description:  Locations that support high densities of a species (“population
 hotspots”) have a disproportionate influence on species’ persistence. In
 fire-prone ecosystems, managers attempting to promote population hotspots
 of multiple species must understand how hotspot locations might shift with
 post-fire succession and how much overlap exists in the locations of
 population hotspots for multiple species. Mangers are then tasked with
 resolving fire-management conflicts in overlapping locations. We studied
 three co-occurring threatened bird species in a fire-prone ‘mallee’ region
 of south-eastern Australia. We undertook field surveys for each species
 (1508 surveys; 540 sites; 9-ha each). We used N-mixture models to
 determine (a) what factors affect species’ density (including post-fire
 succession); (b) species’ population sizes; (c) locations of species’
 current population hotspots and locations that may become population
 hotspots in the future as the post-fire successional state changes and (d)
 the degree of overlap in the current and possible future hotspots of
 species. We found substantial variation in the densities of the three
 species across the study area, with roughly half of each species’
 population occurring in only 20 percent of potential habitat (i.e.
 population hotspots). All species shared a preference for subtle
 depressions in the landscape, resulting in substantial overlap in their
 population hotspots. Two species had contrasting responses to post-fire
 succession in the subtle depressions. As a result, there was only a narrow
 post-fire period that supported population hotspots of both species,
 creating a challenge for fire managers in these shared locations.
 Synthesis and Applications. Many studies make vague recommendations for
 fire-age mosaics that do not provide managers with the detail they need to
 implement appropriate fire-age mosaics. By contrast, we explicitly
 quantify, then balance the conflicting post-fire needs of species in
 locations that support population hotspots of multiple species. Using this
 approach, we develop principles to guide the implementation of fire-age
 mosaics in such locations. This approach represents a step towards
 applying fire-age mosaic theory to support effective species conservation.
description: This is bird survey data collected in the field. 9-ha area
 searches were undertaken during the austral spring of 2019. Repeat surveys
 were used to model detectability. Sites were surveyed 2 to 4 times and
 detection covariates recorded for each survey. Bird species abundances for
 the three study species were also recorded during each survey.  
description: Becasue the number of repeat surveys varied between sites, there
 are missing values where no further surveys were conducted for that site.
 For example, sites that were surveyed only twice have missing values for
 columns relating to the third and fourth rounds of surveys.
