Data from: Transgenerational effects of doxycycline and anhydrotetracycline on the microbiome of the Australian sheep blowfly, Lucilia cuprina
<p>Tetracyclines are a family of broad-spectrum antibiotics commonly used in agriculture, medicine, and research. However, exposure to tetracyclines is associated with a wide range of negative health outcomes. In some cases, these negative effects are transgenerational: when individuals are treated with tetracyclines, their untreated offspring exhibit phenotypic abnormalities. The causes of such transgenerational effects are not well-understood, but disruption of the microbiome and/or mitochondria may play an important role. Transgenerational effects from tetracyclines may threaten the success of an environmentally-friendly form of pest control, the release of transgenic males carrying a tetracycline-repressible female lethal gene. In this study, we investigated the direct and transgenerational effects of two tetracycline-class antibiotics, doxycycline (DOX) and anhydrotetracycline (ATC), on the blowfly<em> Lucilia cuprina</em>, a facultative parasite of sheep. To simulate the rearing conditions used in a male-only release program, blowflies were reared on diet alone, or diet plus DOX or ATC, for three generations, then reared for an additional fourth generation off tetracyclines. We used 16S amplicon sequencing and qPCR to examine whole-body microbiome composition and bacterial and mitochondrial DNA abundance in third and fourth generation flies. The microbiomes of third generation flies reared on DOX or ATC were similar in composition and diversity to the microbiomes of flies reared exclusively on the control diet. However, we found that the untreated fourth generation offspring of DOX- or ATC-treated flies displayed major shifts in microbiome composition relative to both their treated parents and untreated control groups. Our study supports a growing body of evidence that tetracyclines exert both direct and transgenerational effects on arthropods, and highlights the need to address these impacts in the context of insect pest management.</p>
Open access data for 2-year percutaneous osseointegrated implants - A sheep model
<p>Percutaneous osseointegrated <strong>(OI)</strong> devices for amputees are metallic endoprostheses, surgically implanted into the residual bone that protrude through the skin, allowing attachment of an exoprosthetic. In contrast to standard socket-type systems, these percutaneous OI devices can provide an improved prosthetics attachment platform. However, bone adaptations, which include atrophy and/or hypertrophy along the extent of the host bone-endoprosthetic interface, are known clinical outcomes and are dependent upon the load transfer region of the device to the host bone. The goal of this study was to determine if a percutaneous OI device, designed with a porous coated distal region and a collar, could promote and maintain stable bone attachment. A total of eight, 18 to 24-month old, mixed-breed sheep were surgically implanted with a percutaneous OI device. For 24-months, animals were allowed to bear weight as tolerated and monitored for signs of bone remodelling. At necropsy, the endoprosthesis and the surrounding tissues were harvested, radiographically imaged, and histomorphometrically analyzed to determine the periprosthetic bone adaptation in five animals. Bone growth into the porous coating was achieved in all five animals. Serial radiographic data showed stress-shielding related bone adaptation based on the placement of the endoprosthetic stem. When collar placement achieved end-bearing against the transected bone, distal bone conservation/hypertrophy was observed. The results supported the use of distally porous coated percutaneous OI devices for distal load-transfer and host bone maintenance.</p>

Denmark's Not-So-Oldest Sheep: An Update on Domestic Animals from the Femern Project
<p>Sheep and goats are often considered to be the oldest livestock animals in Denmark. In this contribution, we present the results of ZooMS measurements from seven ovicaprid bones from the Femern project, an excavation in the area of the former Syltholm Fjord (Lolland, Denmark). The bones were morphologically identified as sheep or goats and represented the oldest dated remains of both species in Denmark. However, the ZooMS analysis showed that more than half of the morphological identifications were incorrect. For the other samples, we refined the identifications. Hence, our study confirms that indications of sheep and goat husbandry based on bone morphology alone should be treated with caution. The probability of misidentification in our case was high, even in the case of well-preserved bones.</p>
Spatial distribution of cattle, sheep and goat density, and grazed areas for the European Union and the United Kingdom
<p>To improve the sustainability of the European livestock sector we need improved knowledge on livestock density, and also on the grazing patterns. Here we provide spatially explicit data on the distribution of cattle, sheep and goats, developed by combining agricultural and veterinary statistics, in-situ data, expert surveys and machine learning. The data allow for the differentiation between livestock that are grazing on semi-natural areas and managed grasslands, versus those that do not graze and are kept indoors. </p> <p>This dataset covers all European Union Member States and the United Kingdom, and presents the spatial distribution of cattle, sheep and goat density for approximately the year 2020. Livestock density was allocated on the Corine Land Cover data, resulting in a data-set with a 100 m resolution (EPSG: 3035 - ETRS89-extended / LAEA Europe).</p> <p>Together with the livestock density maps, we also provide spatial data on the probability for grazing, and allocated grazed and non grazed areas.</p> <p><strong>File description:</strong></p> <p>The data-set consists of the following files:</p> <p> </p> <ul> <li><strong>clc_forage_mask.tif</strong> , forage areas mask for EU, based on selected Corine Land Cover classes (not including seminatural land cover areas such as natural grasslands...).
