Data from: An expedition to Narcondam: observations of marine and terrestrial fauna including the island-endemic hornbill
<p>Oceanic islands, known for their ecologically sensitive ecosystems and endemic species, are of high conservation significance. The volcanic island of Narcondam in the Andaman and Nicobar Islands, Indian Ocean, is a prime example and the only home of the endemic and globally endangered Narcondam Hornbill. Despite its ecological and evolutionary significance, there has been limited biological exploration and research on the island over the last century. Here, we report on a 2010 expedition to Narcondam, presenting results of our rapid survey of island invertebrates, herpetofauna, mammals and birds (especially the endemic hornbill), and marine life in adjoining waters. The survey recorded dense coral growth in the surrounding waters, and identified 17 fish, 2 sea cucumber, 8 reptile, 28 bird, and 2 mammal species and 13 spider and 8 butterfly taxa. Of these, 4 spiders, 3 butterflies and 6 birds identified to species are new records for the island. The Narcondam Hornbill was frequently encountered and we report trail-based estimates of encounter rate and density, which can serve as a baseline for future monitoring. Both despite its isolation and because of it, Narcondam has faced a number of recent and serious conservation threats, including feral goats, poaching, habitat degradation around the police camp, and proposed installations. While efforts have been made by the Government authorities to stave-off various threats, we highlight the need for further scientific research and monitoring, while according primacy to strict protection and conservation.</p>
Supporting Information for "First Observations of Large Scale Traveling Ionospheric Disturbances Using Automated Amateur Radio Receiving Networks"
<p><strong>Introduction</strong></p> <p>The supporting information for this paper consists of a movie version of Figure 2 in the main paper, comparing the high frequency (HF) amateur radio observations to differential Global Navigation Satellite System (GNSS) Total Electron Content (TEC) measurements. In this revised version of the repository, the TEC data has been reprocessed such that all GNSS data with elevation angles down to 10 degrees were kept when applying the Savitzky–Golay (SG) filter. After the SG filter was applied, data with elevation angles below 30 degrees were discarded. This was done to remove artifacts observed in the original movies.</p> <p> </p> <p><strong>Movie S1 (20171103 Ham and TEC LSTID.mp4)</strong></p> <p>(Top Panel) Time series showing the TX-RX distance for 14 MHz amateur radio spots in 2 min by 25 km bins from 1200 UT 3 Nov 2017 - 0000 UT 4 Nov 2017.

Multi-center observational study on occurrence and related clinical factors of neurogenic heterotopic ossification in patients with disorders of consciousness
<p><strong>Aims</strong>: to assess occurrence and clinical correlates of neurogenic heterotopic ossifications (NHO) in patients with prolonged disorder of consciousness (DoC).<strong>Design</strong>: multi-center cross-sectional observational study.<strong>Setting</strong>: 23 intensive neurorehabilitation units.<strong>Subjects</strong>: 287 patients with prolonged disorder of consciousness (DoC; 150 in vegetative state, VS, and 128 in minimally conscious state, MCS) of different etiology (vascular = 125, traumatic = 83, anoxic = 56, others = 14).<strong>Main Measures</strong>: clinical evidence of NHO confirmed by standard radiological and/or sonographic evaluation; Coma Recovery Scale-Revised; Disability Rating Scale (DRS); Early Rehabilitation Barthel Index; presence of ventilator support, spasticity, bone fractures and paroxysmal sympathetic hyperactivity.<strong>Results</strong>: 31 patients (11.2%) presented NHO. Univariate analyses showed that NHO was associated with VS diagnosis, traumatic etiology, high DRS category and total score, and high occurrence of limb spasticity and bone fractures. A cluster-corrected binary logistic regression model (excluding spasticity available in a subset of patients) showed that only lower DRS total score and presence of bone fractures were independently associated with NHO.<strong>Conclusions</strong>: NHO are relatively frequent in patients with DoC, and are independently associated with functional disability, bone fractures and spasticity. These findings contribute to identifying patients with DoC prone to develop NHO and requiring special interventions to improve functional recovery.</p>

Observational evidence of herbivore-specific associational effects between neighboring conspecifics in natural, dimorphic populations of Datura wrightii
Associational effects – in which the vulnerability of a plant to herbivores is influenced by its neighbors – have been widely implicated in mediating plant-herbivore interactions. Studies of associational effects typically focus on interspecific interactions or pest-crop dynamics. However, associational effects may also be important for species with intraspecific variation in defensive traits. In this study, we observed hundreds of Datura wrightii – which exhibits dimorphism in its trichome phenotype – from over 30 dimorphic populations across California. Our aim was to determine whether a relationship existed between the trichome phenotype of neighboring conspecifics and the likelihood of being damaged by four species of herbivorous insects. We visited plants at three timepoints to assess how these effects vary both within and between growing seasons. We hypothesized that the pattern of associational effects would provide rare-morphs (i.e. focal plants that are a different morph than their neighbors) with an advantage in the form of reduced herbivory, thereby contributing to the negative frequency-dependent selection previously documented in this system. We found the best predictor of herbivory/herbivore presence on focal plants was the phenotype of the focal plant. However, we also found some important neighborhood effects. The total number of plants near a focal individual predicted the likelihood and/or magnitude of herbivory by Tupiochoris notatus, Lema daturaphila, and Manduca sexta. We also found that velvety focal plants with primarily sticky neighbors are more susceptible to infestation by Tupiochoris notatus and Lema daturaphila. This does not align with the hypothesis that associational effects at the near-neighbor scale contribute to a rare-morph advantage in this system. Overall the results of our study show that the number and trichome-morph composition of neighboring conspecifics impact interactions between D. wrightii and insect herbivores.
Impacts of using different standard populations in calculating age-standardized death rates when age-specific death rates in the populations being compared do not have a consistent relationship: A cross-sectional population-based observational study on US state HIV death rates
<p><strong>Objective</strong>: To examine if the rankings of state HIV age-standardized death rates (ASDRs) changed if different standard population (SP) was used.</p> <p><strong>Design</strong>:<strong> </strong>A cross-sectional population-based observational study. Setting 36 states in the United States.</p> <p><strong>Participants</strong>: People died from 2015 to 2019.</p> <p><strong>Main outcome measures</strong>: State HIV ASDR using 4 SPs, namely WHO2000, US2000, US2mor020, and Eur2011–2030.</p> <p><strong>Results</strong>: The rankings of 19 states did not change when ASDRs were calculated using US2000 and US2020. Of the 17 states whose rankings changed, the rankings of 9 states calculated using US2000 were higher than those calculated using US2020; in 8 states, the rankings were lower. The states with the greatest changes in rankings between US2000 and US2020 were Kentucky (12th and 9th, respectively) and Massachusetts (8th and 11th, respectively).</p> <p><strong>Conclusions</strong>: State ASDRs calculated using the current official SP (US2000) weigh middle-age HIV death rates more heavily than older-age HIV death rates, resulting in lower ASDRs among states with higher older-age HIV death rates.</p>
