Sea ice, snow and melt pond example data from MOSAiC transect observations
<p>This data set contains in-situ observation of sea ice, snow and melt pond properties from two days in winter (January 23, 2020) and summer (July 7, 2020) during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. It originates from two sensors:</p> <ol> <li>Broad-band electromagnetic induction sensor (Geophex GEM-2) measuring the combined thickness of the sea ice and snow layers</li> <li>A GPS snow depth probe (Snow-Hydro MagnaProbe) measuring the thickness of the snow layer and melt ponds depth during summer</li> </ol> <p>Both sensors were operated coincidently along transect loops while different loops were used in both days. This data set is a subset of similar weekly activities between October 2019 and September 2020. This publication intends to provide a preview of the data properties and approximate changes between the winter and summer periods. It also has to be noted, that the final data of the EM induction sensor might differ from this release, which is based on a quick-look processing directly after data acquisition.</p> <p><em>GEM-2 data files</em></p> <p>The file format of GEM-2 data is a text file with comma-separated values. Notable parameters are:</p> <ul> <li>‘time’: UTC time</li> <li>‘longitude’: Longitude in degrees east (fill value: 0.0)</li> <li>‘latitude’: Latitude in degrees north (fill value: 0.0)</li> <li>‘`f{frequency}Hz_hcp_{i:Inphase|q:Quadrature}`: total (ice + snow) thickness of the sea ice and snow layers in meter for different channels*</li> </ul> <p>*The channels correspond to the real (Inphase) or imaginary (Quadrature) part of the EM signal at a given frequency. The variable name in the csv file is to be read as `f{frequency}Hz_hcp_{i:Inphase|q:Quadrature}`. It is recommended to use the Inphase component of the 18.325 kHz frequency (variable `f18325Hz_hcp_i`) for analysis.</p> <p><em>MagnaProbe data files</em></p> <p>The file format of MagnaProbe data is a text file with comma-separated values.

Figure 2 in Terrestrial and communal nesting in Eupemphix nattereri (Anura, Leiuperidae): interactions with predators and pond structure
Figure 2. Several aspects of the predation of Eupemphix nattereri by the whistling heron (Syrigna sibilatrix). Above: a couple of herons, each one with an adult E. nattereri in the beak. Middle: a male heron with an amplectant pair of E. nattereri in his beak (the male frog did not release the female and both escaped predation). Below: a female heron washing an adult E. nattereri prior to consumption; note the foam released by the frog while being washed. Note also in the above and middle pictures, the communal foam nests at the pond's margin. More illustrations on several aspects of the natural history of the species are at the Amphibiaweb (http://elib.cs.berkeley.edu).

Figure 1. Above: foam nest anchoring in Eupemphix nattereri. Note that the foam nest (, 40 h old) is on a platform excavated in the soil and far from the water level (thin arrow). There are also platforms (thick arrow) to the left that are unoccupied. Bar,9 cm. Below: a nearly 40-h-old collapsing foam nest. Note the wet mucous string through which the early tadpoles moved towards the water. Scale bar, 6 cm.
Figure 3 in Factors influencing spatial and temporal structure of frog assemblages at ponds in southeastern Brazil
Figure 3. Distribution of nine tadpole species within ponds at Santuário do Caraça, southeastern Brazil, according to variables used to describe microhabitats used by them and period of occurrence, in the first three axes of discriminant space. In the first discriminant axis, smaller values represent larger association to the bottom. In the second axis, the largest values indicate use of deeper microhabitats by tadpoles. In the third axis, larger values indicate species that used both microhabitats with and without aquatic vegetation, and lower values indicate species that used only microhabitats with aquatic vegetation. Centroids for each species are shown on the right.
