Figure 15 in Systematics and zoogeography of the deep-sea hyperbenthic family Arietellidae (Copepoda: Calanoida) collected from the Sulu Sea

Figure 15. Cladogram depicting main habitats and colonization routes for arietellid genera and their presumed ancestors. D, deep-water hyperbenthic; S, shallow-water hyperbenthic (including cavernicolous and epipelagic); P, deep-water planktonic. In the Metacalanus–Metacalanalis–Pilarella-clade there are two possibilities for colonization routes (right: habitat transition from deep-sea to shallow-water hyperbenthos occurred in this clade with re-invasion of Metacalanalis to deep-water hyperbenthos; left: habitat shift from deep-sea to shallow-water hyperbenthos occurred independently in Metacalanus and Pilarella. (O) Habitat shift from deep-sea hyperbenthic to shallow-sea hyperbenthos; (.) habitat shift from shallow-water hyperbenthos to deep-sea hyperbenthos (see text and Figure 14).

Figure 1 in Contributions of Walter G. Ridewood to systematic comparative anatomy, especially of the osteology of ''lower'' vertebrates

Figure 1. Photograph to show how Ridewood disarticulated a fish skull in order to preserve the maximum amount of original articulation as well as to reveal the greater part of the internal skeleton. This is a skull of Scleropages leichardti (Günther 1864). Top: braincase and the right palate, hyomandibular, preopercle and lower jaw shown in medial view. Middle: left palate, hyomandibular and opercular bones in lateral view. Bottom: the ventral gill arches seen in dorsal view. This specimen (The Natural History Museum registration number BMNH 1905.3.20.6) was prepared and used by Ridewood (1905a) in his description of osteoglossid fishes.

Figure 2 in Systematics, variation, and developmental instability: analysis of spine patterns in ancestrulae of a common bryozoan

Figure 2. Some common spine pattern formulae and views of the frontal membrane of ancestralae of Bugula stolonifera. All spine patterns are recorded from the viewpoint of the ancestrula right:left:proximal. (A) Diagram of an ancestrula with the typical 3:3:1 spine pattern cited in the text; (B) 3:3:0 variant spine pattern resulting from a loss of the proximal spine: this spine pattern was the most abundant variant spine pattern accounting for 54% of the variant spine patterns; (C) 3:2:1 variant spine pattern resulting from a loss on the left distal margin; (D) 4:3:1 variant spine pattern resulting from a spine gain on the right distal margin.

(open) data literacy as barrier and enabler of open government data enhancement. A systematic review of the literature.

<p>This systematic review of the literatu was conducted with the PRISMA method, to explore the contexts in which the use of open government data germinates, identifying barriers to its use and identifying, the role of data literacy among those barriers to use; and the role of open data in promoting informal learning that supports the development of critical data literacy.&nbsp;This file includes a codebook of the main characteristics that were studied in a systematic literature review, where data from 66 articles related to Open Data Usage were identified and coded. Also, the file includes an analysis of Cohen&#39;s Kappa, a concordance statistic used to measure the level of agreement among researchers in classifying articles on the characteristics defined in the Codebook. Finally, it includes main tables of the results&#39; analysis.</p>
