Conservation and divergence of cortical cell organization in human and mouse revealed by MERFISH
<p>Please contact Rongxin Fang (r3fang@fas.harvard.edu) for any question about the dataset.</p> <p>The human cerebral cortex has tremendous cellular diversity. How different cell types are organized in the human cortex and how cellular organization varies across species remain unclear. In this study, we performed spatially resolved single-cell profiling of 4000 genes using multiplexed error-robust fluorescence in situ hybridization (MERFISH), identified more than 100 transcriptionally distinct cell populations, and generated a molecularly defined and spatially resolved cell atlas of the human middle and superior temporal gyrus. We further explored cell-cell interactions arising from soma contact or proximity in a cell type–specific manner. Comparison of the human and mouse cortices showed conservation in the laminar organization of cells and divergence in somatic interactions across species. Our data revealed human-specific cell-cell proximity patterns and a marked increase in interaction enrichment between neurons and non-neuronal cells in the human cortex.</p>

Declining freshwater mussel diversity in the middle and lower reaches of the Xin River Basin: Threat and Conservation
<p>Freshwater mussels provide important functions and services for aquatic ecosystems, but populations of many species have been extirpated. Information on biodiversity plays an important role in the conservation and management of freshwater mussels. The Xin River Basin is a biodiversity hotspot for freshwater mussels in China, with more than 43 species known, but populations of which are decreasing. Here, we quantify the diversity of freshwater mussels in the middle and lower reaches of the Xin River Basin and study the correlation of habitat characteristics and freshwater mussel diversity. Compared to the historical period, the number of species, density and biomass of freshwater mussels decreased 33%, 83% and 82% in the current period, respectively. 52% of recorded species were empty shells, and 14 native freshwater mussels were not found in the study area. Four species are currently listed as vulnerable species using IUCN criteria and their global status. The assemblage structure of freshwater mussels exhibits significant spatial differences, and there was a correlation with substrate and physicochemical parameters. The main tributary of the Xin River with higher freshwater mussel diversity should be established as one large protected area because the nestedness component was the main pattern of beta diversity. These results indicated freshwater mussel diversity was declining rapidly, which can help focus conservation effort for freshwater mussel biodiversity.</p>
Museomics contributes to the spatiotemporal assessment of genetic diversity and structure in wild and ex situ conservation organisms: a case study of three endangered coastal plants in Japan
<p><span>Understanding </span><span>the extent to which </span><span>genetic diversity of wild populations in ex</span> <span>situ</span><span> conservation can be retained is </span><span>crucial</span><span> for the management of </span><span>such</span><span> populations. Wild individuals collected in the target area in the past </span><span>and</span><span> present can be used to estimate the number of alleles lost over time in wild populations and</span><span> thereby</span><span> the number of alleles whose loss could be </span><span>prevented</span><span> by ex</span> <span>situ</span><span> conservation. </span><span>Here</span><span>, we assessed the genetic diversity of wild and ex</span> <span>situ</span><span> conservation populations of three endangered coastal herb species</span><span>,</span><span> <em>Cirsium maritimum</em> Makino (Asteraceae), <em>Linaria japonica</em> Miq. (Plantaginaceae</span><span>) and</span><span> <em>Suaeda glauca</em></span><span><em> </em>(Bunge) Bunge (Amaranthaceae), which are endangered </span><span>species on</span><span> Awaji Island, Hyogo Prefecture, Japan, via multiplexed inter-simple sequence repeat genotyping by sequencing (MIG-seq). We </span><span>incorporated</span><span> the museomics approach, which </span><span>involves conducting</span><span> genetic analyses of museum specimens collected from the targeted wild populations in the past to estimate the temporal transition of genetic diversity in wild populations and the number of alleles maintai</span><span>ned in <em>ex situ</em></span><span> conservation. </span><span>Our </span><span>results </span><span>reveal</span><span> a declining trend in genetic diversity in the wild populations of all </span><span>investigated</span><span> species, although </span><span>this trend is </span><span>not significant. In all the species, </span><span>numerous</span><span> alleles were already lost in current wild populations, </span><span>whereas they</span><span> were </span><span>present</span><span> in the past wild and ex</span> <span>situ</span><span> conservation populations. Our study </span><span>indicates</span><span> that extinct alleles in current wild populations have been maintained in ex</span> <span>situ</span><span> conservation</span><span> by museomics approach. These </span><span>appro</span><span>aches </span><span>were effective in verifying</span><span> the genetic diversity retention effects of <em>ex</em></span><em> <span>situ</span></em><span> conservation populations.</span></p>

Figure 5. A representation of the difference in morphology between male Litoria genimaculata and Litoria myola sp. nov. The box plots compare morphology of L. genimaculata from across the Wet Tropics, L. genimaculata from the Kuranda area, and L. myola sp. nov. PC1 accounts for 87.8% of the variation in morphology (SVL, TL, HW, and weight) across L. genimaculata and L. myola sp. nov. PC1 is loaded equally and positively by all four characters (approximately 0.94 for each) and therefore represents body size. The box plots show the median, 25th and 75th quartiles, and minimum and maximum data of PC1.

Figure 4. A representation of the difference in call between Litoria genimaculata and Litoria myola sp. nov. The box plots compare calls of L. genimaculata from across the Wet Tropics, L. genimaculata from the Kuranda area, and L. myola sp. nov. PC1 accounts for 67.2% of the variation in call (duration, dominant frequency and note rate) across L. genimaculata and L. myola sp. nov. PC1 is loaded heavily by inverse call duration (0.95) and note rate (0.93), and moderately by dominant frequency (0.51). The box plots show the median, 25th and 75th quartiles, and minimum and maximum data of PC1.

Figure 6. The distribution of Litoria myola sp. nov. and Litoria genimaculata in the Kuranda area. The pie charts show the proportion of L. myola sp. nov. (black) and L. genimaculata (grey) individuals on five streams. Nearby sites on the streams are grouped together to provide a consistent scale. Sample size for the pie charts averages 20 individuals. The squares show additional sites where L. myola sp. nov. (black squares) and L. genimaculata (grey squares) have been recorded but relative proportions of each have not been determined. All L. genimaculata are northern lineage individuals. Major stream catchments flowing into the Barron River are marked. The sections of stream without records of either species are either unsuitable habitat or have not yet been surveyed. Sites surrounding this area are occupied by northern lineage L. genimaculata or are unsuitable habitat (Fig. 1).
