title: COVID-19 survey in Baja California, Mexico, in February of 2021

description: Baja California is a State located in the north-western region of Mexico,
 which borders with the United States. This area is of particular
 importance in terms of epidemiological surveillance, given that the
 busiest port of entry to the U.S. is located in the Tijuana-San Diego
 region, which is also one of the busiest ports of entry in the world.
 During the first year of the COVID-19 pandemic, Baja California had the
 second mortality rate in Mexico due COVID-19. We conducted a
 cross-sectional study to know the prevalence of COVID-19 in the general
 population at the beginning of 2021, right after the second wave of
 COVID-19 cases in the State. We carried out a population-based survey in
 the 3 largest cities of Baja California, Mexico: Mexicali, Tijuana, and
 Ensenada. The selection of households followed a probabilistic, 3 stage
 approach, with a total of 1,126 individuals included, which were
 representative of a population of 2.7 million after weighting. Real Time
 Polymerase Chain Reaction (RT-qPCR) was used to assess SARS-CoV-2
 infection in nasopharyngeal swabs and IgG seroprevalence was evaluated in
 finger stick blood samples. We also assessed the level of knowledge,
 attitudes, and practices on COVID-19 prevention in the general population.
 In general, Baja California had similar COVID-19 prevalence rate compared
 to other States in Mexico, and crossing the border with the U.S. was not
 associated to higher odds of infection. Ensenada had a higher prevalence
 of COVID-19 by RT-qPCR compared to Tijuana and Ensenada. The
 level of health literacy on COVID-19 shows important areas of opportunity,
 along with a considerable high rate of vaccine hesitancy. Our findings on
 this important area in the Mexico-United States border show that the
 dynamics of COVID-19 are complex, and prevalence rates can significantly
 differ even within the same region. More work needs to be done in terms of
 health promotion in the general population of Baja California in order to
 achieve better health outcomes in future public health emergencies of
 international concern.
description: The survey followed a probabilistic approach for sampling at 3
 levels; the basic geostatistical area, blocks, and households. The survey
 was administered by an interviewer and the data was entered in tablets
 with a previously installed app (KoboToolbox) for data entry. The results
 of sampling testing (RT-PCR and seroprevalence) was captured manually
 afterwards in the dataset generated by KoboToolbox.

title: Precipitation efficiency amplifies climate sensitivity by enhancing tropical circulation slowdown and Eastern Pacific warming pattern

description: Cloud processes are the largest source of uncertainty in quantifying the
 global temperature response to CO2 rise. Still, the role of precipitation
 efficiency (PE) – surface rain per unit column-integrated condensation –
 is yet to be quantified. Here we use 36 limited-domain cloud resolving
 simulations from the Radiative-Convective Equilibrium Model
 Intercomparison Project to show that they strongly imply climate warming
 will result in increases to net precipitation efficiency. We then analyze
 35 General Circulation Models (GCMs) from the Coupled Model
 Intercomparison Project Phase 6 and find that increasing PE enhances
 tropical circulation slowdown and strengthens eastern equatorial Pacific
 warming. These changes trigger pan-tropical positive cloud feedback by
 causing stratiform anvil cloud reduction and stratocumulus suppression,
 and thereby amplify overall climate sensitivity. Quantitatively, we find
 that in the 24 of 35 GCMs which match the cloud-resolving models in
 simulating increasing PE with greenhouse warming, mean Effective Climate
 Sensitivity is 1 K higher than in GCMs in which PE decreases. The models
 simulating increasing PE also comprise all estimates of effective climate
 sensitivity over 4 K. Taken together, these results show that further
 constraining PE sensitivity to warming will reduce uncertainty over future
 climate change.

title: The choanal anatomy of the Sebecus icaeorhinus Simpson, 1937 and the variation of the palatine shape in notosuchians (Crocodyliformes, Mesoeucrocodylia)

description: Sebecidae is a clade of large carnivorous crocodyliforms that thrived in
 the Cenozoic and is the only lineage of the diverse and terrestrial group
 Notosuchia that survived the end-Cretaceous mass extinction event. Sebecus
 icaeorhinus is the best-known taxon from this clade, both in terms of its
 cranial and postcranial anatomy (known primarily from the holotype and the
 specimen MPEF-PV 1776 respectively). An additional material represented by
 a partial skull (MMP 235) is the only specimen that has preserved a
 complete choanal region. Here we describe new information from this
 specimen based on an X-ray computed tomography and identify through
 comparisons with other taxa a large degree of variability in the palatal
 anatomy within Sebecidae, in particular in the shape and extension of the
 palatine (the bone that defines the anterior position and shape of the
 secondary choana). We quantify here the variation in the shape of the
 palatine bone of sebecids through a 2D morphogeometric analysis within the
 context of notosuchian crocodyliforms. Although traditional accounts of
 palatal evolution in crocodyliforms linked variation of this structure to
 the adaptation to the aquatic environment, our analysis allows the
 recognition of eight palatine morphotypes among terrestrial crocodyliforms
 with very distinct paleoecological traits, including carnivorous,
 omnivorous, and possibly herbivorous taxa. Furthermore, we show that
 sebecids had a higher morphological disparity in the choanal region than
 other terrestrial groups of Notosuchia, underscoring the importance of
 this region for comparative, morphofunctional, and phylogenetic studies.

 &lt;i&gt;Sebecus icaeorhinus&lt;/i&gt; Simpson, 1937 and
 the variation of the palatine shape in notosuchians (Crocodyliformes,
 Mesoeucrocodylia) is associated with two appendices (Appendix 1.docx and
 Appendix 2.docx) that contain information that will help the reader to

title: Post-fire Debris Flows: Leveraging Science for Environmental Management and Community Resiliency

description: The movement of soil particles and rocks down hillslopes has affected the
 southern Santa Barbara County foothills over millions of years. The
 landscape has been shaped by the periodic cascades of soil debris in Santa
 Barbara County watersheds. Sediment transport from higher elevations to
 lower elevations, driven by gravity, can be exacerbated by soil cohesion,
 rainfall intensity, wildfire, and topographical relief. The combination of
 these factors influences the overall volume of sediment transported.
 Predicting the volume of a debris flow often has large uncertainty. Debris
 flows can have dire consequences, as evidenced by the post-Thomas Fire
 event on January 9, 2018, where 23 people lost their lives. With the built
 environment encroaching into potential inundation zones, adaptive
 management strategies can limit the risk to those most vulnerable. One
 such strategy is the conversion of existing debris basin infrastructure
 into slotted outfalls, which better facilitate the transport of fine
 sediments downstream while also providing improved fish passage for the
 endangered Southern Steelhead. In addition to infrastructure
 modifications, beneficial reuse of sediment such as beach nourishment
 provide further ways to address this issue, particularly considering a
 changing climate. This project (1) modeled debris flow probabilities and
 volumes with geospatial tools and datasets, (2) evaluated environmental
 and socioeconomic impacts of sediment from debris flows via cost-benefit
 analysis, and (3) examined the broader implications of climate change
 influence on debris flow recurrence and volumes.

title: Coffee Leaf Rust monitoring data on Hawaii Island

description: CLR was detected in Hawaii for the first time in 2020 and quickly spread
 across the state. We initiated a CLR monitoring program in Kona, West
 Hawaii Island to track the spread of this new invasive disease across a
 broad elevational gradient. The goals of the program were to assist
 growers in the early detection of CLR, to characterize patterns of disease
 incidence across the region, and to collect information on farm
 agronomics, management practices, and costs to apply fungicides, all of
 which can be used to develop IPM strategies for this pathogen. We
 monitored 30 coffee lots in Kona, located between 204 and 875 m elevation.
 Average CLR incidence remained below 4% early in the season and increased
 to 36% during harvest. We observed no significant difference in CLR
 incidence between low-, mid- and high-elevation farms. A significant
 reduction in the number of leaves per branch was observed at the end of
 the harvest season, and a significant negative correlation was found
 between the number of leaves per branch and maximum CLR severity. Mean
 disease incidence and mean severity were observed to have a significant
 positive correlation. Incidence increased above threshold levels (5%)
 despite most growers applying preventative fungicides 3-10 times
 throughout the season, suggesting that improved coverage and timing of
 applications is needed along with the addition of systemic fungicides. Our
 study provides the first insights into CLR disease patterns under the
 unique and variable conditions under which Hawaiian coffee is grown and
 will aid in the development of IPM programs that can be used to sustain
 Hawaii’s coffee industry under this new threat.

title: Parameters of leaf phenology for North American forests

description: Leaf phenology regulates multiple aspects of plant vital activities and
 provides feedback to climate change. Despite its importance, an effective
 parameterization method to predict continental-scale leaf phenology has
 been elusive. Here, we developed a new parameterization method using local
 climatic conditions instead of species or plant function types to
 calibrate the phenology parameters of forests. We provided the parameters
 of phenology include: the effective temperature threshold (TA) to
 determine spring phenology (i.e. start of the season; SOS); the critical
 heat threshold (SA) to determine SOS; the effective temperature threshold
 (TB) to determine autumn phenology (i.e. end of the season; EOS); the
 effective photoperiod threshold (Pstart) to determine EOS, and the
 critical chilling threshold (SB) to determine EOS.
description: We used the average
 temperature and photoperiod from the first day to the phenological date in
 a given year to express the climatic conditions. Using this
 parameterization method and the typical phenology models, we extrapolated
 to the continental scale using satellite-derived leaf area index product
 as a basis to predict the distribution and changes of forest leaf
 phenology.

title: Regenerative agriculture can improve productivity and profitability while reducing greenhouse gas emissions on Australian sheep farms

description: This dataset contains raw data, simulation files, and outputs for (1) grazing treatment, (2) pasture species diversity, and (3) antecedent soil organic carbon (SOC), generated using the biophysical model SGS (v5.4.3) in conjunction with DairyMod. Simulations incorporated 100 years (1924–2023) of SILO climate data and representative soil types from the Digital Atlas of Australian Soils. Four sheep farms—WA (F1), SA (F2), VIC (F3), and VIC (F4)—located across key Australian livestock regions, from cool temperate (Victoria) to semi-arid (Western Australia), were modelled using site-specific soil, climate, and management parameters to assess pasture and soil responses under varying environmental conditions.

title: H-O isotopic compositions in China's wetlands

description: Water oxygen isotopic analysis is a useful tool for tracing water cycle in
 aquatic ecosystems on the premise that it is no oxygen isotope effect from
 phytoplankton activity. We measured the water hydrogen and oxygen isotopic
 compositions, phytoplankton Fv/Fm and related environmental factors in
 China's wetlands. We found that phytoplankton photosynthesis can
 modify water oxygen isotopic signature (δ18O), based on a national-scale
 survey of wetlands and a culture experiment. Phytoplankton photosynthesis
 can make water δ18O more negative, and this biological effect counteracts
 part of the evaporation effect on water δ18O. This effect depends on
 phytoplankton biomass and light utilization efficiency and could be
 overwhelmed by the evaporation effect when the biomass is small. The
 biological effect may be universal in aquatic ecosystems, and thus this
 study refreshes the traditional understanding on water oxygen isotope
 biogeochemistry.

title: Echinoderm sperm swimming and fertilization

description: In an era of climate change, impacts on the marine environment include
 warming and ocean acidification. These effects can be amplified in shallow
 coastal regions where conditions often fluctuate widely. This type of
 environmental variation is potentially important for many nearshore
 species that are broadcast spawners, releasing eggs and sperm into the
 water column for fertilization. We conducted two experiments to
 investigate: 1) the impact of water temperature on sperm swimming
 characteristics and fertilization rate in sand dollars (Dendraster
 excentricus) and sea urchins (Mesocentrotus franciscanus) and; 2) the
 combined effects of multiple stressors (water temperature and pH) on these
 traits in sand dollars. We quantify thermal performance curves showing
 that sand dollar fertilization rates, sperm swimming velocities, and sperm
 motility display remarkably wide thermal breadths relative to red urchins,
 perhaps reflecting the wider range of water temperatures experienced by
 sand dollars at our field sites. For sand dollars, both temperature (8,
 16, 24°C) and pH (7.1, 7.5, 7.9) affected fertilization but only
 temperature influenced sperm swimming velocity and motility. Although
 sperm velocities and fertilization were positively correlated, our
 fertilization kinetics model dramatically overestimated measured rates and
 this discrepancy was most pronounced under extreme temperature and pH
 conditions. Our results suggest that environmental stressors like
 temperature and pH likely impair aspects of the reproductive process
 beyond simple sperm swimming behavior.

title: A polygenic architecture with habitat-dependent effects underlies ecological differentiation in Silene

description: Ecological differentiation can drive speciation but it is unclear how the
 genetic architecture of habitat-dependent fitness contributes to lineage
 divergence. We investigated the genetic architecture of cumulative
 flowering, a fitness component, in second-generation hybrids between
 Silene dioica and S. latifolia transplanted into the natural
 habitat of each species. We used reduced-representation sequencing and
 Bayesian Sparse Linear Mixed Models (BSLMMs) to analyze the genetic
 control of cumulative flowering in each habitat. Our results point to a
 polygenic architecture of cumulative flowering. Allelic effects were
 mostly beneficial or deleterious in one habitat and neutral in the other.
 Positive-effect alleles were often derived from the native species,
 whereas negative-effect alleles, at other loci, tended to originate from
 the non-native species. We conclude that ecological differentiation is
 governed and maintained by many loci with small, habitat-dependent effects
 consistent with conditional neutrality. This pattern may result from
 differences in selection targets in the two habitats and from
 environmentally-dependent deleterious load. Our results further suggest
 that selection for native alleles and against non-native alleles acts as a
 barrier to gene flow between species.

title: Data for: Patterns of species diversity in a network of artificial wetlands

description: Aim Artificial island habitats such as human-made wetlands are emerging
 novel ecosystems. Understanding the drivers of diversity in such
 artificial systems is essential for balancing the goals of biodiversity
 conservation and human socio-economic needs.   Location
 Telangana State, India. Methods We surveyed water birds in a network of 57
 artificial wetlands and assessed four macroecological biodiversity
 patterns: spatial beta diversity, temporal beta diversity,
 species-abundance distributions (SADs), and the species–area relationship
 (SAR). We employed a mix of phenomenological and mechanistic models to
 examine the four macro-ecological patterns. We hypothesised that the
 wetland bird communities are primarily structured by
 immigration–extinction dynamics and thus that spatial and temporal beta
 diversity would be high, the within-wetland SADs would exhibit a large
 number of rare species and a monotonically declining overall shape, and
 that the SAR across wetlands would be strongly increasing. 
 Results Spatial and temporal beta diversity were both high and mostly
 attributable to turnover rather than nestedness. While the pooled SAD
 exhibited an interior mode, the SAD for individual wetlands was generally
 log-series distributed, consistent with a model in which immigration among
 wetlands is high. The SAR exhibited an increasing trend, with the
 “small-island effect”, which reflects constraints on immigration and is
 often observed for true island archipelagos, being absent.  Main
 Conclusions We tentatively conclude that bird diversity in this network of
 artificial wetlands is mainly structured by immigration–extinction
 dynamics, although we acknowledge that some of the patterns are also
 consistent with niche dynamics and future research should measure relevant
 biotic and abiotic variables in these wetlands. We encourage future work
 in which our rich data set is used to fit dynamic models that permit more
 detailed quantitative inferences about mechanisms structuring diversity in
 this novel ecosystem, which can ultimately also inform conservation
 management.

title: Patterns of genetic variation and morphology support the recognition of five species in the Gaultheria leucocarpa Blume (Ericaceae) group from mainland China

description: Gaultheria leucocarpa and its varieties form a clade of aromatic shrubs
 that is widely distributed in subtropical and East Asian tropical regions.
 The group is taxonomically difficult and is in need of thorough taxonomic
 investigation. This study focused on taxonomic delimitation within the G.
 leucocarpa group from mainland China. Field surveys covering the
 distributional range of G. leucocarpa in mainland China were conducted,
 wherein four populations from Yunnan and one from Hunan were found bearing
 visibly morphological and habitat differences. A 63-species phylogenetic
 tree of Gaultheria based on one nuclear and three chloroplast markers that
 included samples from the G. leucocarpa group was reconstructed with
 maximum likelihood to clarify the monophyly of the G. leucocarpa group.
 Taxonomic relationships among populations of the G. leucocarpa group were
 investigated with morphology and population genetics, the latter by using
 two chloroplast genes and two low-copy nuclear genes. Based on the sum of
 morphological and genetic analyses, we described three species of
 Gaultheria as new to science, clarified the taxonomic status of G.
 leucocarpa var. pingbienensis, elevating it to the species level, and
 resurrected G. crenulata and treated the varieties G. leucocarpa var.
 crenulata, and G. leucocarpa var. yunnanensis as synonyms of this species.
 We provide a key to the five species now recognized, along with
 descriptions and photographs.

title: A STP-HSI index method for urban built-up area extraction based on multi-source remote sensing data

description: The changes of urban built-up areas can reflect the process of
 urbanization, and it can reflect the population, economy, and cultural
 development of the city. Therefore, accurate and timely extraction of
 urban built-up areas plays an important role in the dynamic management of
 the city. In the existing research, single-source remote sensing data is
 used to extract urban built-up areas, and there is a problem that the
 spectrum of urban areas and non-urban areas is easily confused.
 Multi-source remote sensing data, including luojia-1 remote sensing data,
 Landsat 8 OLI remote sensing data, etc., can make up for the spectrum
 confusing issues. We fuse the time series information of night light
 remote sensing data, neighborhood information and point of interest (POI)
 data in spatial dimension, and propose a built-up area extraction method
 that integrates night light time and space information and POI
 information.
