Present and future distribution of bat hosts of sarbecoviruses: implications for conservation and public health
<p>Global changes in response to human encroachment into natural habitats and carbon emissions are driving the biodiversity extinction crisis and increasing disease emergence risk. Host distributions are one critical component to identify areas at risk of viral spillover, and bats act as reservoirs of diverse viruses. We developed a reproducible ecological niche modelling pipeline for bat hosts of SARS-like viruses (subgenus Sarbecovirus), given that several closely-related viruses have been discovered and sarbecovirus-host interactions have gained attention since SARS-CoV-2 emergence. We assessed sampling biases and modeled current distributions of bats based on climate and landscape relationships and project future scenarios for host hotspots. The most important predictors of species distributions were temperature seasonality and cave availability. We identified concentrated host hotspots in Myanmar and projected range contractions for most species by 2100. Our projections indicate hotspots will shift east in Southeast Asia in locations greater than 2 °C hotter in a fossil-fueled development future. Hotspot shifts have implications for conservation and public health, as loss of population connectivity can lead to local extinctions, and remaining hotspots may concentrate near human populations.</p>
Riverscape heterogeneity in estimated Chinook Salmon emergence phenology and implications for size and growth
<p>Many salmonid-bearing rivers exhibit thermal and hydrologic heterogeneity at multiple spatial and temporal scales, but how this translates into spatiotemporal patterns of fry emergence is poorly understood. Understanding this variability is important because emergence timing determines the biophysical conditions fish first experience (e.g., temperature, flow, food supply), thereby influencing growth opportunities and survival during this critical life stage. We predicted spring Chinook Salmon (<em>Oncorhynchus tshawytscha</em>) emergence phenology across four NE Oregon subbasins over 5-9 years using empirical spawning and temperature data. We then related inter-annual emergence timing estimates to juvenile salmon size and growth rates at consistent sampling locations. There were clear longitudinal patterns of predicted emergence timing in each subbasin: the shape of these patterns was consistent among years, but not among subbasins. In two subbasins emergence occurred progressively later with distance upstream, whereas in the other two subbasins emergence was earliest at upstream sites. Within each year, median emergence dates among sites within each subbasin ranged between 44 and 58 days. This spatial variation was comparable to inter-annual variation, with median emergence dates for a given location in each subbasin ranging between 47 to 74 days among years. Contrary to our expectations, juvenile salmon were not larger in years with earlier emergence, owing to slower spring and summer growth rates compared to years with later emergence. Despite large inter-annual variation in emergence dates, these results suggest that other factors (e.g., stream flow, temperature, density-dependence) were more important than growth duration in determining juvenile salmon growth rates and size among years. We demonstrated considerable spatial and inter-annual variation in emergence phenology within these subbasins. Understanding how this variation translates to spatiotemporal patterns of juvenile salmon habitat use, growth, and survival has important implications for guiding restoration efforts and understanding how climate change may impact these populations.</p>

Data from: Diversity among rare and common congeneric plant species from the Garry oak and Okanagan shrub-steppe ecosystems in British Columbia: implications for conservation
<p>Using universal non-coding chloroplast DNA markers (cpDNA), we investigated genetic diversity and genetic structure in four rare and common plant species pairs inhabiting threatened ecosystems (Garry Oak and Okanagan shrub-steppe) in British Columbia. <span>The species found in the Garry oak ecosystem are:</span><span> </span><em>Sanicula bipinnatifida </em><span>(purple sanicle; Apiaceae; rare),</span><span> </span><em>Sanicula crassicaulis </em><span>(Pacific sanicle; Apiaceae; common), and</span><span> </span><em>Balsamorhiza deltoidea </em><span>(deltoid balsamroot; Asteraceae; rare). The species found in the Okanagan shrub-steppe ecosystem are:</span><span> </span><em>Balsamorhiza sagittata </em><span>(arrowleaf balsamroot; Asteraceae; common),</span><span> </span><em>Orthocarpus barbatus </em><span>(Grand Coulee owl-clover; Orobanchaceae; rare),</span><span> </span><em><u>Orthocarpus </u>luteus </em><span>(yellow owl-clover; Orobanchaceae; common),</span><span> </span><em>Phacelia ramosissima </em><span>(branching phacelia; Hydrophyllaceae; rare), and</span><span> </span><em>Phacelia linearis </em><span>(thread-leaved phacelia; Hydrophyllaceae; common). </span>Eight cpDNA regions were sequenced for each study species. Sequences were aligned and concatenated within each species, and single nucleotide polymorphisms (SNPs) were used to analyze patterns of regional genetic diversity and phylogeographic structure within genera and species.

Geometric Control on Seismic Rupture and Earthquake Sequence along the Yingxiu-Beichuan Fault with Implications for the 2008 Wenchuan Earthquak
<p>A 65000 years seismic sequence is numerical simulated using TriBIE on the unplanar fault plane with variation normal stress. The code is now available in an open-source Git-hub project, <a href="https://github.com/daisy20170101/TriBIE/tree/normal_stress_variation">https://github.com/daisy20170101/TriBIE/tree/normal_stress_variation</a>.</p> <p>The modeling will output the bianary format files of normal stress, fault slip velocity, shear stress, slip during the interseismic loading and coseismic rupture stage, respectively. Since it is impossible to output the data at every time step, especially for the large-scale fault model. Thus, during the interseismic loading, we set a constant time interval to output data and the t-inter-***.dat file will record every time, when the data is outputted. During coseimic rupture, t-cos-**.dat file records time of outputing data. So, the size of t-inter-**.dat and t-cos-**.dat file is the number of outputting steps.The fault plane is discretized into 3,1440 elements and the simulation is carried out by parallel computing on 6 servers with 120 CPUs . Each CPU will dispose data of 262 elements. </p> <p> </p> <p> </p> <p> </p> <p> </p>
