NASA Sun Photometry Data at the Sevilleta National Wildlife Refuge, New Mexico (1994-present)
A sun photometer was installed at the Sevilleta Field Station in 1994.It is part of a network of such instruments deployed around the world within a program called AERONET (AErosol RObotic NETwork http://aeronet.gsfc.nasa.gov/new_web/system_descriptions.html) established by NASA to obtain a measure of atmospheric aerosols around the globe.  Individual photometer units are designed to view the sun and sky at preprogrammed intervals throughout the day for the measurement of aerosol optical thickness, water vapor amounts, ozone levels, particle size distribution, aerosol scattering, phase function, and single scattering albedo.  These measurements can also be used to radiometrically correct satellite imagery.  The unit consists of A) the photometer, B) a robot for directing the photometer at the sun, C) a CIMEL datalogger which directs the data collection and storage, D) a DCP (Data Collection Platform) which controls hourly data transmission to the GOES satellite and E) an antenna for facilitating this DCP to satellite link.  Solar measurements are made at 1021, 871, 669, 498, 437, 379, and 339 nm.  The Sevilleta LTER is responsible for maintenance of the unit on site while NASA takes care of data processing and and storage and annual re-calibration of the unit.  Data can be obtained from NASA via:http://aeronet.gsfc.nasa.gov/cgi-bin/type_piece_of_map_opera_v2_new.
Bird Species Present at Barro Colorado Island, Panama
Patterns of biodiversity, such as the increase toward the tropics and the peaked curve during ecological succession, are fundamental phenomena for ecology. Such patterns have multiple, interacting causes, but temperature emerges as a dominant factor across organisms from microbes to trees and mammals, and across terrestrial, marine, and freshwater environments. However, there is little consensus on the underlying mechanisms, even as global temperatures increase and the need to predict their effects becomes more pressing. The purpose of this project is to generate and test theory for how temperature impacts biodiversity through its effect on biochemical processes and metabolic rate. A combination of standardized surveys in the field and controlled experiments in the field and laboratory measure diversity of three taxa -- trees, invertebrates, and microbes -- and key biogeochemical processes of decomposition in seven forests distributed along a geographic gradient of increasing temperature from cold temperate to warm tropical. This list of bird species at Barro Colorado Island, Panama, was retrieved from http://biogeodb.stri.si.edu/biodiversity/bci/ on 10/17/2013 as part of a macrosystems biodiversity and latitude project supported by the National Science Foundation under Cooperative Agreement DEB#1065836.
Past Causalities and Event Categories for Connecting Similar Past and Present Causalities
<p>This dataset includes past causalities and their categories to connect similar past and present causalities. We report how to use this dataset in the following papers.</p> <p><em>Ryohei Ikejiri, Yasunobu Sumikawa: "Developing world history lessons to foster authentic social participation by searching for historical causation in relation to current issues dominating the news".

We first collect past causalities by referencing the textbooks. We then select the causalities if they can be useful for considering solutions for present social issues. To enhance the analogy, we describe each causality in three kinds of texts: background including problems, solution ways, and their results. From the selected causalities and an Encyclopedia of Historiography, we define categories for them. Finally, the created dataset contains 138 past causalities and 13 categories. Each past causality has more than one categories.</p> <p>To help training machine learning models, this dataset additionally provides 900 past event data in past_events_wikipedia.tsv. The event data were collected from Wikipedia, and then were assigned one or more categories from the above 13 ones.

Data from: Ten-year survival trends of neovascular age-related macular degeneration at first presentation
<p><b>Background:</b> To describe 10-year trends in visual outcomes, anatomical outcomes, and treatment burden of patients receiving anti-vascular endothelial growth factor (VEGF) therapy for neovascular age-related macular degeneration (nAMD).</p> <p><b>Methods: </b>Retrospective cohort study of treatment-naïve, first-affected eyes with nAMD started on ranibizumab before January 1, 2009. The primary outcome was time to best-corrected visual acuity (BCVA) falling ≤ 35 Early Treatment Diabetic Retinopathy Study (ETDRS) letters after initiating anti-VEGF therapy. Secondary outcomes included time to BCVA reaching ≥ 70 letters; proportion of eyes with BCVA ≥ 70 and ≤ 35 letters at 10 years; mean trend of BCVA and central retinal thickness (CRT) over 10 years; and mean number of injections.</p> <p><b>Results: </b>For our cohort of 103 patients, Kaplan-Meier analyses demonstrated median time to BCVA reaching ≤35 and ≥70 letters were 37.8 (95% CI 22.2-65.1) and 8.3 (95% CI 4.8-20.9) months after commencing anti-VEGF therapy, respectively. At the final follow-up, BCVA was ≤35 letters and ≥70 letters in 41.1% and 21%, respectively, in first-affected eyes, whilst this was the case for 5.4% and 48.2%, respectively, in a patient's better-seeing eye. Mean injection number was 37.0 ± 24.2 per eye and 53.6 ± 30.1 at patient-level (63.1% of patients required injections in both eyes). </p> <p><b>Conclusions: </b>The chronicity of nAMD disease and its management highlights the importance of long-term visual prognosis. Our analyses suggest that one in five patients will retain good vision (BCVA ≥70 ETDRS letters) in the first-affected eye at 10 years after starting anti-VEGF treatment; yet one in two patients will have good vision in their better-seeing eye. Moreover, our data suggest that early treatment of nAMD is associated with better visual outcomes.</p>
Flexible habitat choice by aphids exposed to multiple cues reflecting present and future benefits
Mothers choose suitable habitats for laying offspring to maximize fitness. Since habitat quality varies in space and time, mothers gather information to choose among available habitats through multiple cues reflecting different aspects of habitat quality at present and in the future. However, it is unclear how females assess and integrate different cues associated with current rewards and future safety to optimize oviposition/larviposition decisions, especially across small spatial scales. Here we tested the individual and interactive effects of leaf surface, leaf orientation and leaf bending direction on larviposition site choice and fitness benefits of wheat aphids (<i>Metopolophium dirhodum</i>) within individual leaves. We found that females preferred upper over lower surfaces for gaining current food-related rewards, downward- over upward-facing surfaces for avoiding potential abiotic risks, and sunken over protruding surfaces for avoiding potential biotic risks. When facing conflicting cues during larviposition, females preferred downward-facing/sunken surfaces over upper surfaces, suggesting that females prioritize potential safety at the cost of current rewards during decision making. Most importantly, our combined-cue experiments showed females still assessed secondary cues (i.e. the upper surface) when first-ranked cues (i.e. the downward-facing/sunken surface) are available, even though females only gained relatively small fitness rewards through secondary cues, and females can integrate different cues associated with current rewards and potential safety in a multiplicative way to make flexible and complex larviposition decisions. Overall, our findings provide new insights into how animals collect and process multi-cue information associated with current rewards and potential safety to maximize fitness at small spatial scales.

FIGURE 5. Cainozoic species diversity of Cantharidinae and Trochinae (red bars) compared with the stable isotope record (δ18O) of Zachos et al. (2001), which can roughly be read as climate record. Important geodynamic and climatic events are given in yellow (MMCO = Middle Miocene Climate Optimum, MSC = Messinian Salinity Crisis). No clear relation between global climate, geodynamic events and trochid evolution can be deduced form the data. Note that the endemic Sarmatian radiation is not shown in the figure.
