The impact of within-host coinfection interactions on between-host parasite transmission dynamics varies with spatial scale
<p>Within-host interactions among coinfecting parasites can have major consequences for individual infection risk and disease severity. However, the impact of these within-host interactions on between-host parasite transmission, and the spatial scales over which they occur, remain unknown. We developed and applied a novel spatially explicit analysis to parasite infection data from a wild wood mouse (<em>Apodemus sylvaticus</em>) population. We previously demonstrated a strong within-host negative interaction between two wood mouse gastrointestinal parasites, the nematode <em>Heligmosomoides polygyrus,</em> and the coccidian <em>Eimeria hungaryensis</em>, using drug-treatment experiments. Here, we show this negative within-host interaction can significantly alter the between-host transmission dynamics of <em>E. hungaryensis</em>, but only within spatially-restricted neighbourhoods around each host. However, for the closely related species <em>E. apionodes</em>, which experiments show does not interact strongly with <em>H. polygyrus</em>, we did not find any effect on transmission over any spatial scale. Our results demonstrate that the effects of within-host coinfection interactions can ripple out beyond each host to alter the transmission dynamics of the parasites, but only over local scales that likely reflect the spatial dimension of transmission. Hence there may be knock-on consequences of drug treatments impacting the transmission of non-target parasites, altering infection risks even for non-treated individuals in the wider neighbourhood.</p>
External Stakeholders Survey Results - The Future of Aquaculture The impact of 4.0 technologies worldwide
<p>Aquaculture 4.0 technologies have landed and are very likely to stay, aiming to play a major role within the implementation of new Circular Bioeconomy approaches. In this context, European aquaculture has been recently applying innovative and disruptive technologies to transform fishery management strategies. The so-called “4th industrial revolution” is projected to allow a 15-20% increase in the sector by the year 2030. In addition to the growth the revolution can provide, the benefits of Industry 4.0 include improved productivity, efficiency and reduced costs. Companies will be able to produce more, in less time, while allocating resources more effectively, due to a smooth adoption of interconnectivity through the Internet of Things (IoT), access to real-time data, and the introduction of cyber-physical systems. According to FAO data, the estimated production volume of fish from European aquaculture in 2028 will increase to approximately 1.4 million tons, needing more circular, digitized solutions to cover end user demand.</p> <p>This data was collected from a survey investigating the Future of Aquaculture The impact of 4.0 technologies worldwide. The results of this survey were used to understand the main challenges faced within the Aquaculture 4.0 market concerning usage experience and level of awareness, in order to identify barriers for implementation and key drivers to encourage adoption of innovative technologies within their businesses. The insights gathered will help us to improve our concept and ultimately the whole value chain of the Aquaculture 4.0 market.</p>

Train and Evaluation Code, Road Classification Models and Test set of the paper "Impact of Image Resolution and Image Overlap on the Prediction Performance of Convolutional Neural Networks Trained for Road Classification"
<p>This repository contains the Python scripts built for training and evaluation of the implementation, together with the test data and the resulting road classification models corresponding to the paper "Impact of Image Resolution and Image Overlap on the Prediction Performance of Convolutional Neural Networks Trained for Road Classification". The scripts make use of the Tensorflow with Keras framework and the additional required dependencies.</p> <p>The training and validation set is based on the binary SROADEX dataset (https://zenodo.org/records/6482346) that was re-split into tiles that feature the image resolutions (256 x 256, 512 x 512, and 1024 x 1024 pixels) and image overlaps (0% and 12.5%) considered in this study. The data have been generated using scripts developed in Python using Open Source libraries (GDAL/OGR and MapScript) for rasterization of vector cartography that represents the axes of the different types of roads (urban, interurban and rural). This binary road data contains information from 16 full orthoimages (28.5 km * 18.5 km) with spatial resolution of 0.5 m/pixel from the insular and peninsular Spanish territory. Due to the size on disk of approximately 546 gigabytes, this training and validation data is only available upon request from the corresponding author. The test set has been generated from a novel area of 28.5 km * 18.5 km and features binary road labels. The test sets are provided in the repository for each resolution (with no overlap), so that additional DL models can be evaluated on the same data and compared with the results achieved in this study.</p> <p>The structure of the information shared in this repository is as follows:<br>The scripts have been grouped by tile resolution (256, 512 and 1024). First, the test set and the evaluation script can be found. For each tile resolution, there are two subfolders (corresponding to the "no overlap" and "12.5% overlap"). In each case, the Python scripts for training the models in the three repetitions are shared, and the trained models (H5 format) are shared in compressed form. Finally, for each resolution we also share the testing dataset which consists of two folders.</p> <p>The material is distributed under a CC-BY 4.0 license.</p>

Data from: Do the health benefits of boiling drinking water outweigh the negative impacts of increased indoor air pollution exposure?
<p><strong>Background: </strong>Billions of the world's poorest households are faced with the lack of access to both safe drinking water and clean cooking. One solution to microbiologically contaminated water is boiling, often promoted without acknowledging the additional risks incurred from indoor air degradation from using solid fuels.</p> <p><strong>Objectives: </strong>This modeling study explores the tradeoff of increased air pollution from boiling drinking water under multiple contamination and fuel use scenarios typical of low-income settings.</p> <p><strong>Methods: </strong>We calculated the total change in disability-adjusted life years (DALYs) from indoor air pollution (IAP) and diarrhea from fecal contamination of drinking water for scenarios of different source water quality, boiling effectiveness, and stove type. We used Uganda and Vietnam, two countries with a high prevalence of water boiling and solid fuel use, as case studies. </p> <p><strong>Results: </strong>Boiling drinking water reduced the diarrhea disease burden by a mean of 1110 DALYs and 368 DALYs per 10,000 people for adults and children <5 years in Uganda, respectively, for high-risk water quality and the most efficient (lab-level) boiling scenario, with smaller reductions for less contaminated water and ineffective boiling. Similar results were found in Vietnam, apart from fewer avoided DALYs in children due to different demographics. In both countries, for households with high baseline IAP from existing solid fuel use, adding water boiling to cooking on a given stove was associated with a limited increase in IAP DALYs due to the log-linear dose-response curves. Boiling, even at low effectiveness, was associated with <em>net </em>DALY reductions for medium- and high-risk water, even if using unclean stoves/fuels. Replacing traditional stoves with improved stoves coupled with effective boiling practices significantly reduced total DALYs. </p> <p><strong>Discussion: </strong>Boiling water generally resulted in a net decrease in DALYs. Future efforts should empirically measure health outcomes from IAP vs. diarrhea associated with boiling drinking water using field studies with different boiling methods and stove types.</p>
Dataset: Impact of early Danian environmental perturbations on mid-latitude planktic foraminiferal assemblages from the ODP Site 1262 (South Atlantic Ocean)
<div> <div> <div> <p><span>After the mass extinction at the Cretaceous/Paleogene (K/Pg) boundary (~66 Ma), life forms quickly radiated to occupy ecological niches in the world’s oceans. Nevertheless, the aftermath of the Chicxulub impact, the massive volcanism of the Deccan Traps and climatic perturbations endured during the early Danian. The impact of consequent carbon cycle perturbations on nascent plankton communities, such as the Dan-C2 event (~65.80 to ~65.71 Ma), is still poorly known. In this work, we present a detailed study of planktic foraminiferal assemblages from Ocean Drilling Program (ODP) Site 1262 (Walvis Ridge, South Atlantic Ocean), spanning the first ~400 kyr of the Danian. No relevant perturbations in planktic foraminiferal assemblages and carbonate preservation indices have been identified at Site 1262 during the Dan-C2 event. Approximately 50 kyr before the beginning of the Dan-C2 event, a Hg-rich interval, potentially linked to the emplacement of the Ambenali Formation of the Deccan Traps massive volcanism, is recorded between ~65.95 and 65.82 Ma. It coincides with an increase in aberrant planktic foraminifera (~65.93 to ~65.82 Ma), allowing to establish a cause-effect relationship. Additionally, a bloom of triserial guembelitriids was recognized between ~65.87 and ~65.78 Ma, also preceding the Dan-C2 event but lagging the Hg-rich interval and the bloom of aberrant planktic foraminifera. The lag time between the first volcanic episode and ecosystem response may be due to factors such as an inefficient biological pump and increases in temperature, microbial activity and food supply at the ocean surface. A second Hg-rich interval identified between ~65.70 and ~65.65 Ma has been tentatively tied to the Mahabaleswar Formation of the Deccan Traps. Neither the second volcanic episode nor the Dan-C2 event resulted in relevant environmental perturbations at Site 1262. This suggests that, although volcanism may have had an impact on early plankton communities in the early Danian through metal contamination, marine ecosystems likely became progressively more stable and resistant to changes in volcanic emissions and the carbon cycle. </span></p> </div> </div> </div>
Data from: Quantifying the impact of internal variability on the CESM2 control algorithm for stratospheric aerosol injection dataset
<p>Earth system models are a powerful tool to simulate the response to hypothetical climate intervention strategies, such as stratospheric aerosol injection (SAI). Recent simulations of SAI implement tools from control theory, called "controllers", to determine the quantity of aerosol to inject into the stratosphere to reach or maintain specified global temperature targets, such as limiting global warming to 1.5C above pre-industrial temperatures. This work explores how internal (unforced) climate variability can impact controller-determined injection amounts using the Assessing Responses and Impacts of Solar climate intervention on the Earth system with Stratospheric Aerosol Injection (ARISE-SAI) simulations. Since the ARISE-SAI controller determines injection amounts by comparing global annual-mean surface temperature to predetermined temperature targets, internal variability that impacts temperature can impact the total injection amount as well. Using an offline version of the ARISE-SAI controller and data from CESM2 earth system model simulations, we quantify how internal climate variability and volcanic eruptions impact injection amounts. While idealized, this approach allows for the investigation of a large variety of climate states without additional simulations and can be used to attribute controller sensitivities to specific modes of internal variability.</p>

Each ear is set at an angle relative to the midline of the fish., The otolith organs,, the semicircular canals (enlarged areas are the ampullae regions that contain the sensory cells);, the dense calcarious otolith lying in close proximity to the sensory epithelium ().

FIGURE 5 in An overview of fish bioacoustics and the impacts of anthropogenic sounds on fishes
FIGURE 5 The sensory epithelia of the end organs of the inner ear have numerous mechanoreceptive sensory hair cells. The apical ends of these cells, directed into the lumen of the epithelia, have ciliary bundles (inserts in the figure) consisting of a single kinocilium (longest of the cilia) and graded stereocilia. Bending of the ciliary bundle during sound stimulation results in neurotransmitter release to stimulate the 8th cranial nerve. The sensory cells on the otolith maculae are organized into orientation groups, with all of the cells in each group having their kinocilia in the same general direction. In this typical saccular epithelium (anterior to the left, dorsal to the top), the cilia on the rostral end are oriented rostrally or caudally, while the cells on the caudal end are oriented dorsally and ventrally., The approximate dividing lines between orientation groups)

FIGURE 1 in An overview of fish bioacoustics and the impacts of anthropogenic sounds on fishes
FIGURE 1 Fish hearing sensitivity (thresholds) obtained under open sea, free-field, conditions in response to pure tone stimuli at different frequencies. The lower the thresholds (y-axis), the more sensitive the fish is to a sound. Thus, Clupea harengus has best hearing of all of these species over a wider range of frequencies. Note that the thresholds in Gadus morhua and C. harengus obtained under quiet conditions may be below natural ambient noise levels, especially at their most sensitive frequencies. In the presence of higher levels of noise, the thresholds would be raised, a phenomenon referred to as masking. Gadus morhua and C. harengus are sensitive to both sound pressure and particle motion, whereas Limanda limanda and Salmo salar are only sensitive to particle motion. The reference level for the particle velocity is based on the level that exists in a free sound field for the given sound pressure level. n.b., For the particle velocity levels in this figure to match the sound pressure levels in a free sound field it is necessary to calculate an appropriate particle velocity reference level. If the standard reference levels are used, then the curves will not match one another and so they are not included here to keep the figure relatively simple. Fig. © 2018 Anthony D.
