A long-term study of size variation in Northern Goshawk Accipiter gentilis across Scandinavia, with a focus on Norway
<p><span>Changing climate and growing human impacts are resulting in globally rising temperatures and the widespread loss of habitats. How species will adapt to these changes is not well understood. The Northern Goshawk (<em>Accipiter</em> <em>gentilis</em>) can be found across the Holarctic but is coming under more intense pressure in many places. Studies of recent populations in Finland and Denmark have shown a marked decline in body size of Northern Goshawks over the past century. Here we investigate long-term changes to Norwegian populations of Northern Goshawk by including material from the Middle Ages. We measured 240 skeletons of modern Northern Goshawks from Norway, Sweden, Denmark and Finland, and 89 Medieval Goshawk bones. Our results show that Norwegian and Swedish female Goshawks have decreased in size over the past century, whilst males showed little decline. Medieval female Goshawks were larger than contemporary females. A decline in forest habitats and a concomitant shift towards smaller prey likely drove a shift to smaller body size in Northern Goshawks. Our study shows that significant body size changes in birds can occur over relatively short time spans in response to environmental factors, and that these effects can sometimes differ between sexes. </span></p>

Data for: Predation and biophysical context control long-term carcass nutrient inputs in an Andean ecosystem
<p>Animal carcass decomposition is an often-overlooked component of nutrient cycles. The importance of carcass decomposition for increasing nutrient availability has been demonstrated in several ecosystems, but impacts in arid lands are poorly understood. In a protected high desert landscape in Argentina, puma predation of vicuñas is a main driver of carcass distribution. Here, we sampled puma kill sites across three habitats (plains, canyons, and meadows) to evaluate the impacts of vicuña carcass and stomach decomposition on soil and plant nutrients up to 5 years after carcass deposition. Soil beneath both carcasses and stomachs had significantly higher soil nutrient content than adjacent reference sites in arid, nutrient-poor plains and canyons, but not in moist, nutrient-rich meadows. Stomachs had greater effects on soil nutrients than carcasses. However, we did detect higher plant N concentrations at kill sites. The biogeochemical effects of puma kills persisted for several years and increased over time, indicating that kills do not create ephemeral nutrient pulses, but can have lasting effects on the distribution of soil nutrients. Comparison to broader spatial patterns of predation risk reveals that puma predation of vicuñas is more likely in nutrient-rich sites, but carcasses have the greatest effects on soil nutrients in nutrient-poor environments, such that carcasses increase localized heterogeneity by generating nutrient hotspots in less productive environments. Predation and carcass decomposition may thus be important overlooked factors influencing ecosystem functioning in arid environments.</p>
Prevalence and characteristics of long COVID-19 in Jordan: A cross sectional survey
<p>Early in the pandemic, the spread of the emerging virus SARS-CoV-2 was causing mild illness lasting less than two weeks for most people, with a small proportion of people developing serious illness or death. However, as the pandemic progressed, many people reported suffering from symptoms for weeks or months after their initial infection. Persistence of COVID-19 symptoms beyond one month, or what is known as long COVID-19, is recognized as a risk of acute infection. Up to date, information on long COVID-19 among Jordanian patients has not been reported. Therefore, we sought to conduct this cross-sectional study utilizing a self-administered survey. The survey asks a series of questions regarding participant demographics, long COVID-19 symptoms, information about pre-existing medical history, supplements, vaccination history, and symptoms recorded after vaccination. Chi square analysis was conducted on 990 responders, and the results showed a significant correlation (P<0.05) between long COVID-19 syndrome and age, obesity, chronic illness, vitamin D intake, number of times infected by COVID-19, number of COVID-19 symptoms and whether the infection was pre or post vaccination. The long-term symptoms most enriched in those with long COVID-19 were tinnitus (73.4%), concentration problems (68.6%) and muscle and joint ache (68.3%). A binomial logistic regression analysis was done to explore the predictors of long COVID-19 and found that age 18-45, marital status, vitamin D, number of COVID-19 symptoms and signs after vaccination are positive predictors of long COVID-19, while zinc intake is a negative predictor. Although further studies on long-term persistence of symptoms are needed, the present study provides a baseline that allows us to understand the frequency and nature of long COVID-19 among Jordanians.</p>
Dynamics of leaching of POPs and additives from plastic in a Procellariiform gastric model: Diet and polymer dependent effects and implications for long-term exposure
<p>Procellariiform seabirds are known to have high rates of plastic ingestion. We investigated the bioaccessibility of plastic-associated chemicals [plastic additives and sorbed persistent organic pollutants (POPs)] leached from plastic over time using an in vitro Procellariiform gastric model. High-density polyethylene (HDPE) and polyvinyl chloride (PVC), commonly ingested by Procellariiform seabirds, were manufactured with one additive [decabrominated diphenyl ether (PBDE-209) or bisphenol S (BPS)]. HDPE and PVC added with PBDE-209 were additionally incubated in salt water with 2,4,4'-trichloro-1,1'-biphenyl (PCB-28) and 2,2',3,4,4',5'-hexachlorobiphenyl (PCB-138) to simulate sorption of POPs on plastic in the marine environment. Our results indicate that the type of plastic (nature of polymer and additive), presence of food (i.e., lipids and proteins) and gastric secretions (i.e., pepsin) influence the leaching of chemicals in a seabird. In addition, 100% of the sorbed POPs were leached from the plastic within 100 hours, while only 2-5% of the additives were leached from the matrix within 100 hours, suggesting that the remaining 95% of the additives could continue to be leached. Overall, our study illustrates how plastic type, diet and plastic retention time can influence a Procellariform's exposure risk to plastic-associated chemicals.</p>
Inside Long House, Mesa Verde National Park
Long House was made by a pre-Pueblo culture "Long House was built c. 1200; it was occupied until 1280. The cliff dwelling features 150 rooms, a kiva, a tower, and a central plaza.[157] Its rooms are not clustered like typical cliff dwellings. Two overhead ledges contain storage space for grain. One ledge seems to include an overlook with small holes in the wall to see the rest of the village below. A spring is accessible within several hundred feet, and seeps are located in the rear of the village." https://en.wikipedia.org/wiki/Mesa_Verde_National_Park#Long_House https://www.nps.gov/meve/learn/historyculture/cd_long_house.htm Created in RealityCapture from 1350 images in 18h:25m:32s.

Long Case Grandfather Clock with Moon Dial
The Long Case or Floor Clock was invented in the mid-17th century with pendulums calibrated to swing once a second. Thereafter these became items of high-end decoration as well as reliable time pieces. In the early 18th century, the moon or lunar dial was added. Around 1876 Long Case Clocks became better known as 'grandfather clocks' due to a popular song retelling the story of the song-writers putative grandfather's clock. This model would stand 1.95 metres tall, which is a typical size. Source: Objaverse 1.0 / Sketchfab

Long-term oriented culture, performance pressure and corporate innovation evidence from China
<p>This paper extracts cultural elements of long-term orientation from Chinese listed firms' annual reports, then argues and testifies whether long-term orientation can help firms to hang onto risky decisions especially as innovation, when firms are under performance pressure. There are three main conclusions. First, we report that the higher the degree of long-term oriented culture a firm has, the stronger innovation capability the firm shows. Second, we find that long-term oriented culture can improve employee's educational qualifications to promote corporate innovation, as well as improve the corporate internal control to promote innovation. Third, when firms are subjected to internal or external performance pressure in their business process, higher long-term oriented culture will make firms more innovative.</p>

Long-distance electron transfer along redox gradients in the subsurface
<p>Electron transfer (ET) is the fundamental process of life and element cycling. In the subsurface, the distance of ET determines its influencing area, normally as short as nanometers or micrometers. Here we provide direct evidence from column experiments that ET can last over 10 cm along the redox gradient in sediment columns, through a long-distance ET chain constituted by a series of short-distance electron hopping reactions involving with microbes and redox-active species like iron ions (and/or minerals) and natural organic matters. Microbial processes contribute largely under biologically active conditions, while chemical processes are important under extremely acidic/alkaline and cold conditions. Microbial and chemical processes synergistically mediate the long-distance ET process, with an estimated electron flux of 6.73 μmol e<sup>-</sup>/cm<sup>2</sup> per day. This long-distance ET represents an overlooked but important background process influencing subsurface biogeochemical processes and remediation activities.</p>
Coral community metabolism during year-long exposure to experimental elevated CO2 conditions
<p>The implications of ocean acidification are acute for calcifying organisms, notably tropical reef corals, for which accretion generally is depressed and dissolution enhanced at reduced seawater pH. We describe year-long experiments in which back reef and fore reef (17-m depth) communities from Moorea, French Polynesia, were incubated outdoors under pCO<sub>2</sub> regimes reflecting endpoints of representative concentration pathways (RCPs) expected by the end the century. Incubations were completed in 3–4 flumes (5.0 × 0.3 m, 500 L) in which seawater was refreshed and circulated at 0.1 m s<sup>-1</sup>, and the response of the communities was evaluated monthly by measurements of net community calcification (NCC) and net community photosynthesis (NCP). For both communities, NCC (but not NCP) was affected by treatments and time, with NCC declining with increasing pCO<sub>2</sub>, and for the fore reef, becoming negative (i.e., dissolution was occurring) at the highest pCO<sub>2</sub> (1067–1433 µatm, RCP8.5). There was scant evidence of community adjustment to reduce the negative effects of ocean acidification, and inhibition of NCC intensified in the back reef as the abundance of massive <em>Porites</em> spp. declined. These results highlight the risks of dissolution under ocean acidification for coral reefs and suggest these effects will be most acute in fore reef habitats. Without signs of amelioration of the negative effects of ocean acidification during year-long experiments, it is reasonable to expect that the future of coral reefs in acidic seas can be predicted from their current known susceptibility to ocean acidification.</p>
