Fig. 2 in PHYLOGENETIC SYSTEMATICS OF DART-POISON FROGS AND THEIR RELATIVES (AMPHIBIA: ATHESPHATANURA: DENDROBATIDAE)
Fig. 2. Hypothesized phylogeny of dendrobatids, redrawn from Myers et al. (1991: 29, fig. 20). All evidence is shown on the cladogram. In this scenario, Aromobates nocturnus is postulated to be the sister species of all other dendrobatids. All of the unquestioned synapomorphies listed for Dendrobatidae apply only to A. nocturnus and are unknown in any other dendrobatid.
Fig. 8 in PHYLOGENETIC SYSTEMATICS OF DART-POISON FROGS AND THEIR RELATIVES (AMPHIBIA: ATHESPHATANURA: DENDROBATIDAE)
Fig. 8. Hypothesized phylogeny of dendrobatids, redrawn from Widmer et al. (2000: 561, fig. 2), based on parsimony analysis of cytochrome b sequences aligned with Clustal W (Thompson et al., 1994) (parameters not specified). Numbers are parsimony/maximum likelihood/neighbor-joining bootstrap frequencies.

Fig. 4. Hypothesized phylogeny of dendrobatids, redrawn from Kaplan (1997: 373, fig. 3). Numbered synapomorphies are: (1) tympanum posterodorsally tilted under anterior edge of massive superficial slip of m. depressor mandibulae, (2) mercaptanlike defensive odor, (3) diurnal activity, (4) riparian–terrestrial habitat preference, (5) smaller size (,50 mm SVL), (6) m. adductor mandibulae externus superficialis absent (''s'' pattern), (7) neopalatines absent, (8) finger three of males swollen, and (9) lipophilic alkaloids present.

Fig. 12. Hypothesized phylogeny of Dendrobates, redrawn from Symula et al. (2003: 459, fig. 3), based on maximum likelihood (under the GTR + C model) analysis of cytochrome b and cytochrome oxidase I DNA sequences aligned with ClustalX (Thompson et al., 1997) (parameters not specified).

Fig. 4. Forest Islands 1, 2 in The Blue Dyeing Poison-Dart Frog, Dendrobates tinctorius (Dendrobates azureus, Hoogmoed 1969): extant in Suriname based on a rapid survey
Fig. 4. Forest Islands 1, 2, and 4, extant vegetation comparison between Google Earth images for 2004 (A) and 1969 (B). Red outlines delineating the three forest islands were juxtaposed from the 2004 image onto the 1969 image.
Fig. 1 in The Blue Dyeing Poison-Dart Frog, Dendrobates tinctorius (Dendrobates azureus, Hoogmoed 1969): extant in Suriname based on a rapid survey
Fig. 1. Map of Suriname, South America (upper left inset) with approximate location of Sipaliwini savannah indicated by the black box. Forest Islands are outlined in red and identified by numbers corresponding to those of Hoogmoed (1969, 2019). Arrows indicate locations of the 50 x 50 m plots surveyed in Forest Islands 1, 2, and 4 during 16–18 June 2015. Forest Island 3 was not surveyed. In this 2004 Google image, savanna vegetation surrounding the forest islands had been recently burned by indigenous hunters.
FIG, 1. John William Daly (1933–2008) on the upper Río San Juan. This paper is dedicated to John Daly, our late friend and colleague, who helped collect three of the new species here described. In addition to his globally acclaimed discoveries in chemistry and pharmacology, John was an accomplished field herpetologist who contributed importantly to the systematics and natural history of dendrobatoid frogs (see Grant et al., 2006; Myers, 2009). This photograph shows John at age 37, with the upper Río San Juan behind him and branches overhead of a madroño tree (probably Garcinia magnifolia, syn. Rheedia chocoensis, Clusiaceae). When in South America, John was never far from a dendrobatid frog—this time, in the tree above his head, a tiny, undescribed semiarboreal species (also collected and later named "Dendrobates fuguritus" by our colleague Philip Silverstone). Other dendrobatids found nearby included Phyllobates aurotaenia (Boulenger, 1913), which was then being used for poisoning blowgun darts, and also the nontoxic species that we name Silverstoneia dalyi herein.

Myers, 2 km above Playa de Oro, Chocó, February 16, 1971.) in Review of the Frog Genus Silverstoneia, with Descriptions of Five New Species from the Colombian Chocó (Dendrobatidae: Colostethinae)

WACCMX DART Ionosphere Data Assimilation Observing System Simulation Experiment
This dataset contains output from the data assimilation version of the Whole Atmosphere Community Climate Model with thermosphere-ionosphere eXtension (WACCMX DART). The dataset includes model output fields of electron column density, temperature, and zonal wind as well as DART observation space diagnostics. The results are based on a series of Observing System Simulation Experiments that are aimed at evaluating the assimilation of ionospheric observations in WACCMX DART. Included are files from the OSSE truth simulation, as well as from three experiments: Experiment 1: No ionosphere data assimilation. Experiment 2: Ionosphere data assimilation without thermosphere constraint. Experiment 3: Ionosphere data assimilation with thermosphere constraint. The dataset is in support of the publication "Assimilation of Ionosphere Observations in the Whole Atmosphere Community Climate Model with thermosphere-ionosphere eXtension (WACCMX)".
Movies associated with "Direct N-body simulations of satellite formation around small asteroids: insights from DART's encounter with the Didymos system"
<pre>All movies are titled based on the figure in the paper they correspond to and the ID number of the simulation. All movies, except for movie_fig1_fig2_spinup.mp4 are rendered in a rotating, primary-centered frame with a period of 10 hours. This is done to make it easier to watch the satellite accumulate. movie_fig1_fig2_spinup.mp4 is rendered in an inertial frame. The movies are quite long, so we recommend fast-forwarding some of the boring parts :)</pre>
