Vascular Flora Surveys of Permanent Plots at the Harvard Farm at Harvard Forest since 2015

The objectives of this study were to: (1) Determine the species richness and cover of vascular flora in 27 permanent plots at the Harvard Farm (established in HF236). (2) Track any changes in species richness and species dominance in the plant communities at each plot over time. (3) Observe any changes in invasive species richness and cover over time. (4) Identify differences between plant community composition of plots in constant grazing, rotational grazing, and mowing areas. These data were collected by Harvard Forest interns and may include some misidentifications, but they should be considered accurate for larger scale analyses of changes in the density of growth forms and invasive species. For more accurate species-level information, please see data collected every five years by Glenn Motzkin (HF236 with data from 2014 and 2019).

Vascular Territory template and atlases in MNI space

<p><strong>Data</strong></p> <p>Sixteen subjects (mean age (sd): 69.6 (8.2); 37.5% female) were recruited to generate a high-resolution template. The cohort consists of twelve stroke-free, non-demented patients with the sporadic form of cerebral amyloid angiopathy (CAA), and similarly-aged healthy controls (n=4). Each participant underwent high-resolution MRI&nbsp;with a Siemens Magnetom Prisma 3T scanner (using a 32-channel head coil) as part of a separate study. The standardized protocol included a Multiecho T1-weighted (voxel size: 1x1x1 mm<sup>3</sup>; Repetition Time [TR]: 2510 ms), a 3D-FLAIR (voxel size: 0.9x0.9x0.9 mm<sup>3</sup>; TR: 5000 ms; TE: 356 ms), and a T2-weighted Turbo Spin Echo (voxel size: 0.5x0.5x2.0 mm<sup>3</sup>; TR: 7500 ms; TE: 84 ms) sequence. Scans were manually assessed to ensure no gross pathology was present, such as hemorrhage or silent brain infarcts.</p> <p><strong>Template and territorial map creation</strong></p> <p>We employed Advanced Normalization Tools (ANTs) for image processing (Avants et al., 2010, 2011) for creating a brain template based on multimodal information using T1, T2 and 3D-FLAIR sequences. After template creation, we smoothed the resulting templates (FSL; Gaussian smoothing, sigma = 1) and registered the resulting templates into MNI space, again using ANTs (Avants et al., 2011).</p> <p>Vascular territories were outlined on the right hemisphere in the T1-weighted atlas image and contain anatomically validated ACA, MCA, and PCA territories supratentorially. The right hemispheric map was then mirrored onto the left hemisphere to create a full-brain vascular territory map, which was manually assessed and corrected where necessary.</p> <p>&nbsp;</p> <p>For more details, please see the original publication that utilized the template.

Species richness of vascular plants and bryophytes in nine grassland sites (Europe and California collected in 2013-2016)

We sampled vascular plants (VP) and bryophytes (non-vascular plant; NVP) 1×1 m experimental plots in nine sites belonging to the Nutrient Network. Three sites were in California, two in Finland and UK and one in Germany and Switzerland. The data were collected to compare the responses of NVPs and VPs to nutrient addition and grazing exclusion treatments. The NVP and VP cover sampling was conducted in March-August 2016, except for heron.uk and rook.uk, which had been sampled for VPs in 2013. NVPs were mostly identified to species, but in absence of necessary diagnostic characters (capsules, other reproductive organs, distinctive gametophytic features), some specimens were identified at morphospecies group, subgenus, or genus level. We calculated three plant diversity indices for NVPs, VPs and total (NVPs and VPs combined) in each plot. First, species richness (S) is the number of species per 1 m2 for NVPs and VPs. For plots having no NVPs, NVP richness is zero. Second, for plots having at least one NVP, we calculated Inverse Simpson’s index of diversity (referred to as species diversity), which is equivalent to the Probability of Interspecific Encounter or Effective Number of Species (ENSPIE). Third, we calculated Simpson’s evenness (E = ENSPIE/S; referred to as evenness), which was expected to reflect changes in species’ dominance. We also sampled aboveground plant biomass at peak biomass of vascular plants (in May- August, depending on local site level characteristics) by clipping at ground level and removing all aboveground vegetation (live and dead) from two 0.1 × 1 m strips, sorting the current year’s VP and NVP biomass from the previous year’s biomass (dead litter), drying the biomass to a constant mass at 60 °C, and weighing it to the nearest 0.01 g. Except for two sites (heron.uk and rook.uk), we also measured photosynthetically active radiation (PAR) at the ground surface and above grassland canopy at time of peak biomass and calculated the proportion of tra

Cover and frequency of biological soil crust community types, moss species, vascular plants, and abiotic land surface features, on gypsum & non-gypsum soils from the Chihuahuan and Mojave Deserts in 2023

This dataset contains raw and calculated percent cover and frequency data for biological soil crust (hereafter biocrust) functional groups, vascular plant functional groups, and abiotic land surface features on and off gypsum soils in the northern Chihuahuan and eastern Mojave Deserts. Abundance data were obtained from 20 study sites total, 10 located on soils derived from gypsum parent material and 10 located on soils derived from non-gypsum parent materials. Sites were grouped into 10 pairs, in which every gypsum site was partnered with a non-gypsum site located in the same region. Apart from soil type, partnered-site characteristics (topography, climate, elevation, slope, aspect, and presence of biocrusts) were held relatively constant. At each site, cover and frequency assessments were made using the line-point intercept method (LPI) and frequency quadrats (1.0 m^2), respectively. Biocrust functional groups included the following crusts: lichen, moss, incipient algal, light algal, dark algal, unknown photosynthetic crust, and vagrant cyanobacteria. Vascular plant categories included: perennial forbs, perennial graminoids, annual forbs, annual graminoids, subshrub, shrub, Yucca, and cacti. Abiotic land surface features included: woody litter, herbaceous litter, bare soil, rock, bedrock, and animal feces. Moss crusts identified within cover and frequency analyses were sampled, and classified to species level via microscopy. The resulting percent cover and frequency data was used to understand differences in biocrust and moss species abundance and diversity on and off gypsum soils; furthermore, how biocrust and moss species abundance was associated with the measured environmental variables. Soil physical and chemical data from this study can be accessed at knb-lter-jrn.210616002. This study and dataset are complete.

Histological Dataset for Microvascular Segmentation of Tissue-Engineered Vascular Grafts

<p><strong>Objectives: </strong>The pursuit of understanding vascular tissue regeneration within tissue-engineered vascular grafts (TEVGs) is of paramount importance due to the critical role these grafts play in replacing damaged or diseased blood vessels. TEVGs offer a promising alternative to traditional grafts, with the potential to integrate into the host's tissue and support the natural regenerative processes. However, challenges such as thrombosis, inflammation, and the need for grafts that can adapt to the dynamic biological environment remain. By studying the regenerative processes in TEVGs, researchers can gain insights into the mechanisms that underpin successful graft integration and function, which is essential for improving patient outcomes in vascular surgeries. This dataset, with its detailed annotations of histological features, provides a valuable resource for developing and refining machine-learning models that can analyze and predict patterns of vascular tissue regeneration. The ability to accurately segment and quantify microvessels and immune cells in regenerated arteries is a significant step forward in distinguishing between physiological and pathological regeneration, ultimately contributing to the design of more effective and reliable TEVGs for clinical use.</p> <p><strong>Ethical Approval: </strong>Experimental strategy of the study is described in detail in <a href="https://www.mdpi.com/2073-4360/14/23/5149" target="_blank" rel="noopener">[1]</a> and <a href="https://www.mdpi.com/1422-0067/24/10/8540" target="_blank" rel="noopener">[2]</a>. The study was conducted according to the guidelines of the Declaration of Helsinki, and was approved by the Local Ethical Committee of the Research Institute for Complex Issues of Cardiovascular Diseases (Kemerovo, Russia, protocol code 2020/06, date of approval: 19 February 2020). Animal experiments were performed in accordance with the European Convention for the Protection of Vertebrate Animals (Strasbourg, 1986) and Directive 2010/63/EU of the European Parliament on the protection of animals used for scientific purposes. For the implantation, we used female Edilbay sheep of 42&ndash;45 kg body weight which were received from the Animal Core Facility of the Research Institute for Complex Issues of Cardiovascular Diseases (Kemerovo, Russia) and selected for the surgery by Doppler ultrasonography to identify those having carotid artery diameter of 4.0 &plusmn; 0.2 mm.</p> <p><strong>Description: </strong>The dataset comprises a collection of Whole Slide Images (WSIs) obtained from biodegradable TEVGs implanted into the carotid arteries of 20 sheep. A total of 104 WSIs were acquired, each measuring an average size of 135,000 x 123,000 pixels. These WSIs were stained using Hematoxylin and Eosin (H&amp;E), a common practice for highlighting the structure of tissue sections, which facilitates the detailed examination of histological features. These WSIs were automatically sliced into 99,831 patches of 3,000 x 3,000 pixels and subsequently filtered, resulting in 1,401 selected patches for manual annotation.</p> <p><strong>Annotation Method:</strong> Two pathologists independently selected and meticulously annotated the 1401 patches, identifying nine distinct histological features associated with vascular tissue regeneration. These features include <em>arteriole lumen (AL)</em>, <em>arteriole media (AM)</em>, <em>arteriole adventitia (AA)</em>, <em>venule lumen (VL)</em>, <em>venule wall (VW)</em>, <em>capillary lumen (CL)</em>, <em>capillary wall (CW)</em>, <em>immune cells (IC)</em>, and <em>nerve trunks (NT)</em>. The annotations were performed using binary masks, delineating each feature within the patches. Subsequently, a senior pathologist conducted a triple verification process, reviewing and refining the annotations to ensure accuracy and consistency. The annotations are provided in the form of binary masks, meticulously defined for each feature within the patches.</p> <p><strong>Dataset Split:</strong> Given the limited number of subjects studied, comprising 20 sheep, we employed a 5-fold cross-validation technique to split our dataset. This method was chosen because it allows for the efficient use of limited data, ensuring that each observation has the opportunity to be used in both the training and testing sets, thus reducing bias and providing a more accurate estimate of the model's performance. In this approach, each fold involved 16 sheep for training and the remaining 4 for testing (see <em>Table 1</em> and <em>Figure 3</em>). This partitioning scheme was consistently applied to maintain the integrity of subject groups within each subset and to prevent data leakage. The 5-fold cross-validation is particularly beneficial for our study's objectives as it maximizes the training data available for developing robust machine learning models while also ensuring that the models are tested on unseen data, thereby enhancing the generalizability of our findings.</p> <p><strong>Access to the Study:</strong> Further information about this study, including curated source code, dataset details, and trained models, can be accessed through the following repositories:</p> <ul> <li><strong>Source code:</strong>&nbsp;<a href="https://github.com/ViacheslavDanilov/histology_segmentation" target="_blank" rel="noopener">https://github.com/ViacheslavDanilov/histology_segmentation</a></li> <li><strong>Dataset:</strong>&nbsp;<a href="https://doi.org/10.5281/zenodo.10838384" target="_blank" rel="noopener">https://doi.org/10.5281/zenodo.10838384</a></li> <li><strong>Models:</strong>&nbsp;<a href="https://doi.org/10.5281/zenodo.10838431" target="_blank" rel="noopener">https://doi.org/10.5281/zenodo.10838431</a></li> </ul> <div>&nbsp;</div> <div><em><strong>Table 1.</strong> Patch and feature distributions across folds and subsets</em> <table> <tbody> <tr> <td> <p><strong>Fold</strong></p> </td> <td> <p><strong>Subset</strong></p> </td> <td> <p><strong>Patches</strong></p> </td> <td> <p><strong>AL</strong></p> </td> <td> <p><strong>AM</strong></p> </td> <td> <p><strong>AA</strong></p> </td> <td> <p><strong>VL</strong></p> </td> <td> <p><strong>VW</strong></p> </td> <td> <p><strong>CL</strong></p> </td> <td> <p><strong>CW</strong></p> </td> <td> <p><strong>IC</strong></p> </td> <td> <p><strong>NT</strong></p> </td> <td> <p><strong>Total </strong></p> </td> </tr> <tr> <td> <p>1</p> </td> <td> <p>Train</p> </td> <td> <p>1168</p> </td> <td> <p>510</p> </td> <td> <p>512</p> </td> <td> <p>220</p> </td> <td> <p>675</p> </td> <td> <p>648</p> </td> <td> <p>770</p> </td> <td> <p>765</p> </td> <td> <p>409</p> </td> <td> <p>448</p> </td> <td> <p>4957</p> </td> </tr> <tr> <td>1</td> <td> <p>Test</p> </td> <td> <p>233</p> </td> <td> <p>81</p> </td> <td> <p>84</p> </td> <td> <p>36</p> </td> <td> <p>186</p> </td> <td> <p>169</p> </td> <td> <p>178</p> </td> <td> <p>182</p> </td> <td> <p>91</p> </td> <td> <p>25</p> </td> <td> <p>1032</p> </td> </tr> <tr> <td> <p>2</p> </td> <td> <p>Train</p> </td> <td> <p>1053</p> </td> <td> <p>406</p> </td> <td> <p>411</p> </td> <td> <p>179</p> </td> <td> <p>678</p> </td> <td> <p>638</p> </td> <td> <p>743</p> </td> <td> <p>746</p> </td> <td> <p>423</p> </td> <td> <p>315</p> </td> <td> <p>4539</p> </td> </tr> <tr> <td>2</td> <td> <p>Test</p> </td> <td> <p>348</p> </td> <td> <p>185</p> </td> <td> <p>185</p> </td> <td> <p>77</p> </td> <td> <p>183</p> </td> <td> <p>179</p> </td> <td> <p>205</p> </td> <td> <p>201</p> </td> <td> <p>77</p> </td> <td> <p>158</p> </td> <td> <p>1450</p> </td> </tr> <tr> <td> <p>3</p> </td> <td> <p>Train</p> </td> <td> <p>1127</p> </td> <td> <p>507</p> </td> <td> <p>511</p> </td> <td> <p>222</p> </td> <td> <p>743</p> </td> <td> <p>702</p> </td> <td> <p>759</p> </td> <td> <p>760</p> </td> <td> <p>299</p> </td> <td> <p>423</p> </td> <td> <p>4926</p> </td> </tr> <tr> <td>3</td> <td> <p>Test</p> </td> <td> <p>274</p> </td> <td> <p>84</p> </td> <td> <p>85</p> </td> <td> <p>34</p> </td> <td> <p>118</p> </td> <td> <p>115</p> </td> <td> <p>189</p> </td> <td> <p>187</p> </td> <td> <p>201</p> </td> <td> <p>50</p> </td> <td> <p>1063</p> </td> </tr> <tr> <td> <p>4</p> </td> <td> <p>Train</p> </td> <td> <p>1064</p> </td> <td> <p>466</p> </td> <td> <p>472</p> </td> <td> <p>199</p> </td> <td> <p>611</p> </td> <td> <p>566</p> </td> <td> <p>759</p> </td> <td> <p>758</p> </td> <td> <p>423</p> </td> <td> <p>291</p> </td> <td> <p>4545</p> </td> </tr> <tr> <td>4</td> <td> <p>Test</p> </td> <td> <p>337</p> </td> <td> <p>125</p> </td> <td> <p>124</p> </td> <td> <p>57</p> </td> <td> <p>250</p> </td> <td> <p>251</p> </td> <td> <p>189</p> </td> <td> <p>189</p> </td> <td> <p>77</p> </td> <td> <p>182</p> </td> <td> <p>1444</p> </td> </tr> <tr> <td> <p>5</p> </td> <td> <p>Train</p> </td> <td> <p>1192</p> </td> <td> <p>475</p> </td> <td> <p>478</p> </td> <td> <p>204</p> </td> <td> <p>737</p> </td> <td> <p>714</p> </td> <td> <p>761</p> </td> <td> <p>759</p> </td> <td> <p>446</p> </td> <td> <p>415</p> </td> <td> <p>4989</p> </td> </tr> <tr> <td>5</td> <td> <p>Test</p> </td> <td> <p>209</p> </td> <td> <p>116</p> </td> <td> <p>118</p> </td> <td> <p>52</p> </td> <td> <p>124</p> </td> <td> <p>103</p> </td> <td> <p>187</p> </td> <td> <p>188</p> </td> <td> <p>54</p> </td> <td> <p>58</p> </td> <td> <p>1000</p> </td> </tr> </tbody> </table> </div> <p>&nbsp;</p>

Summary statistics accompanying the article "Genome-wide association study of the human brain functional connectome reveals strong vascular component underlying global network efficiency" in Scientific Reports (2022)

<p>Summary statistics for genome-wide association studies reported in:</p> <p>Bell, S., Tozer, D.J., &amp; Markus H.S. (2022). Genome-wide association study of the human brain functional connectome reveals strong vascular component underlying global network efficiency. <em>Scientific Reports</em>, DOI: <a href="https://dx.doi.org/10.1038/s41598-022-19106-7">10.1038/s41598-022-19106-7</a>.&nbsp;</p> <p><strong>Abstract</strong></p> <p>Complex brain networks play a central role in integrating activity across the human brain, and such networks can be identified in the absence of any external stimulus. We performed 10 genome-wide association studies of resting state network measures of intrinsic brain activity in up to 36,150 participants of European ancestry in the UK Biobank. We found that the heritability of global network efficiency was largely explained by blood oxygen level-dependent (BOLD) resting state fluctuation amplitudes (RSFA), which are thought to reflect the vascular component of the BOLD signal. RSFA itself had a significant genetic component and we identified 24 genomic loci associated with RSFA, 157 genes whose predicted expression correlated with it, and 3 proteins in the dorsolateral prefrontal cortex and 4 in plasma. We observed correlations with cardiovascular traits, and single-cell RNA specificity analyses revealed enrichment of vascular related cells. Our analyses also revealed a potential role of lipid transport, store-operated calcium channel activity, and inositol 1,4,5-trisphosphate binding in resting-state BOLD fluctuations. We conclude that that the heritability of global network efficiency is largely explained by the vascular component of the BOLD response as ascertained by RSFA, which itself has a significant genetic component.</p> <p>&nbsp;</p> <p>Further information on the files uploaded here can be found in the README.

Deep and complex vascular anatomy in the rat brain described with Ultrasound Localization Microscopy in 3D

<p><strong>Abstract:</strong></p><p>Ultrasound Localization Microscopy (<strong>ULM</strong>) enables imaging microvessels in the brain with a resolution of a few tens of micrometers <i>in vivo</i>. The planar architecture of arterioles and venules was revealed with a 2D ultrasound scanner in the cortex of the rat brain. However, deeper in the brain, where the vascularization becomes tri-dimensional, 2D imaging remains limited by the elevation projection. In this study, volumetric ultrasound imaging was performed in the craniotomized rat brain to yield 3D ULM<i> in vivo</i> within 7.5 min of acquisition with a commercial system. For instance, it highlighted the thalamus or the circle of Willis with small vessels down to 21 µm. Microbubbles tracking also gave access to the 3D velocity vector of blood flow allowing to distinguish flow directions. Volumetric ULM resolved deep complex tri-dimensional vascular structures&nbsp;and was compared to 2D ULM. It is a safe, simple and repeatable system to image wide field of view in the brain.</p><p><strong>Data Description:</strong></p><p>Microbubbles have been detected, localized, and tracking with 3D ultrasound imaging <i>in vivo</i> in a rat brain with skull removal.</p><p>Individual microbubble trajectories are described in 4 columns vectores: <strong>[z, x, y, time]</strong> for each position of the path. Space positions are given in [mm], and times are given in [ms]. Trajectories data are stored in .mat files (<strong>tracks_0xx.mat </strong>and zipped inside <strong>tracks.zip</strong>) as cell arrays.</p><p>Tracks can be binned inside a volumetric grid with the sample code (<strong>ULM_rendering.m</strong>).</p><p><strong>Reference to be cited: </strong>Chavignon, Heiles, Hingot, Orset, Vivien and Couture.</p><p><i>Deep and complex vascular anatomy in the rat brain described with Ultrasound Localization Microscopy in 3D.</i><br>&nbsp;</p>

Alaskan Peatland Experiment: Community structure and productivity data for 2007-2010 IV - Understory Vascular ANPP

This dataset contains net primary productivity (NPP, g/m2/yr) measurements for understory vascular components of the plant community collected at peak biomass in the summer of 2009 at the Alaskan peatland experiment. Two peatland types are included, a bog site and a fen site. Within the fen site a water table manipulation has been ongiong since 2005, with control, lowered and raised water table treatment plots. Samples at the bog were collected in a plot established within the lowland black spruce permafrost plateau (permafrost), and two plots established within collapse scars embedded within the plateau. One collapse scar formed ~ 45 years ago (old collapse) and the other formed ~ 25 years ago based upon aerial photography provided by the BCEF LTER. The data provided in this data set can be sorted by site and plot.
