Out to Lunch: Saks & koehler Reply to Rudin & Imman\u27s Commentary
No full textAt several points in their comment on our article in Science (1), Rudin & Inman (2, 3) asserted or clearly implied that we had been dishonest in our presentation. In each of those instances Rudin & Inman\u27s charges are groundless, as we demonstrate below.
Had Rudin & Inman examined the actual source [see Fig. 1, right], they would have discovered that the words were indeed those of Moenssens, that they were consistent with the context in which they appeared, that Moenssens was not quoting Zain or anyone else, and that Saks & Koehler had accurately attributed the statement to its author, Andre Moenssens
Amphipholis bananensis Koehler 1911

Amphiopholis clypeata: Koehler 1914: 19; A. M. Clark 1955: 38; Longhurst 1958: 100. Material examined. St. BE 17: grab sampling, 17 ° 18.946´S, 11 ° 43.389´E; 15 specimens, 2–5 mm. Depth: 26 m. This species only occurred at this station. Diagnosis. The oral papillae are arranged in a continuous series with the distal one being at least twice as broad as the other ones. A few specimens bear an extra oral papilla in some jaw angles, distally to the broad papilla at the adoral plate. Oral shields are distinctly longer than broad. Disc scales are fine and primary plates are evident. There are two scales at each tentacle pore. Distribution. Northern West Africa: Ivory Coast and southwards, southern West Africa: Angola (17 °S, previously known only as far south as 8 °S) and northwards, at littoral depths.Published as part of Glück, Franziska U., Stöhr, Sabine, Bochert, Ralf & Zettler, Michael L., 2012, Brittle stars (Echinodermata: Ophiuroidea) from the continental shelf off Angola and Namibia, pp. 1-20 in Zootaxa 3475 on page 7, DOI: 10.5281/zenodo.28223
Ophiopsila guineensis Koehler 1914

Clark 1955: 50; Longhurst 1958: 99; Buchanan 1958: 30; Tommasi 1967: 548; Madsen 1970: 223. Material examined. St. 66: dredge sampling, 9 ° 33.702´S, 13 °06.018´E; 1 specimen, 8 mm. Depth: 20 m. This species appeared just once. Diagnosis. Unfortunately the disc of this specimen is only partly complete, but as the typical leopard-like pattern is clearly visible, it can be easily identified. Moreover two enlarged inner tentacle scales crossing each other on the midline of each arm joint are characteristic of this species. There is an apical vertical cluster of spines (or tooth papillae) at the apex of the jaw accompanied by a continuous series of small lateral oral papillae. Distribution. This species is certainly recorded from the Mediterranean (Stöhr, personal observation) and as far south as Annobón Island in tropical West Africa. It is the first time that this species is recorded as far south off West Africa in general and off Angola in particular. Ophiopsila guineensis occurs at depths from 18 to 175 m.Published as part of Glück, Franziska U., Stöhr, Sabine, Bochert, Ralf & Zettler, Michael L., 2012, Brittle stars (Echinodermata: Ophiuroidea) from the continental shelf off Angola and Namibia, pp. 1-20 in Zootaxa 3475 on page 12, DOI: 10.5281/zenodo.28223

Clark 1955: 48; Longhurst 1958: 99; Cherbonnier 1962: 15; 1963: 186; Madsen 1970: 217; Alva & Vadon 1989: 833. Material examined. St. 66: dredge sampling, 9 ° 33.702´S, 13 °06.018´E; 1 specimen, 6.5 mm. Depth: 20 m. This species appeared just once. Diagnosis. Unfortunately half of the disc has been damaged and arms are broken. But it is clearly visible that disc scales as well as the radials are densely covered with uniform spinelets, which also extend to the ventral side. Arms carry erect and free arm spines that are quite long, glassy and thorny. There is a cluster of spines at the apex of the jaw but no lateral oral papillae. Distribution. Northern West Africa: Guinea and southwards, southern West Africa: just to the south of Luanda, Angola (9 °S) and northwards. It occurs from the intertidal zone to 65 m.Published as part of Glück, Franziska U., Stöhr, Sabine, Bochert, Ralf & Zettler, Michael L., 2012, Brittle stars (Echinodermata: Ophiuroidea) from the continental shelf off Angola and Namibia, pp. 1-20 in Zootaxa 3475 on page 14, DOI: 10.5281/zenodo.28223
Ophiopteron atlanticum Koehler 1914

Clark 1955: 49; Cherbonnier 1957: 163; Longhurst 1958: 99; Tommasi 1967: 541; Madsen 1970: 218; Alva & Vadon 1989: 833. Material examined. St. 66: dredge sampling, 9 ° 33.702´S, 13 °06.018´E; 2 specimens, 3–3.5 mm. Depth: 20 m. Diagnosis. The presence of long and erect arms spines connected by a thin skin is a striking and reliable identifying character of the genus Ophiopteron. The disc of Ophiopteron atlanticum is armed with bayonet-like spinelets, spines or thorns, but armature is absent on the radial shields and the centrodorsal plate or only sparsely covering these. The jaw bears a compact cluster of small apical spines but no lateral oral papillae. Distribution. Northern West Africa: Senegal and southwards, southern West Africa: just to the south of Luanda, Angola (9 °S) and northwards. It is the first time that this species was found as far south off Angola as described here. The previous southernmost boundary was Musserra (7 °S). Ophiopteron atlanticum has a depth range of 11 to 120 m.Published as part of Glück, Franziska U., Stöhr, Sabine, Bochert, Ralf & Zettler, Michael L., 2012, Brittle stars (Echinodermata: Ophiuroidea) from the continental shelf off Angola and Namibia, pp. 1-20 in Zootaxa 3475 on page 14, DOI: 10.5281/zenodo.28223

Cadenat (1938) identified numerous animals from an area that the author referred as Cape Blanc and Cape Verde as <i>Ophiacantha</i> sp., though none of the specimens came from the later archipelago but from Dakar. Regardless Cadenat remarked that these brittle stars were quite close to what Koehler described as <i>Ophiacantha brevispina</i>. Later, Bartsch (1987) recorded <i>O</i>. <i>brevispina</i> from the same region as the previous author. Bartsch erroneously listed the Azores under geographical range of this species (citing Cadenat 1938), mistaking the Cape Verde Islands with the Azores.</p>Published as part of <i>Madeira, Patrícia, Kroh, Andreas, Cordeiro, Ricardo, De, António M., Martins, Frias & Ávila, Sérgio P., 2019, The Echinoderm Fauna of the Azores (NE Atlantic Ocean), pp. 1-231 in Zootaxa 4639 (1)</i> on page 163, DOI: 10.11646/zootaxa.4639.1, <a href="http://zenodo.org/record/3342161">http://zenodo.org/record/3342161</a>
Political militaries in popular uprisings: A comparative perspective on the Arab Spring
No full text© 2016, © The Author(s) 2016. What determines whether militaries will defect from authoritarian incumbents during regime crises? Variance in military behavior in the Arab Spring has given rise to a debate around this issue. This article highlights weaknesses of the dominant explanation and develops an alternative account of military behavior in ‘endgame scenarios’. If militaries are politicized institutions that play a major role in regulating access to power under authoritarianism, they are more likely to intervene during normal times, but less likely to defect during mass uprisings. I quantitatively test this argument against data on military coups between 1975 and 2000 drawing on a new variable that allows me to explicitly model the impact of major regime crises. I illustrate the emergence of different forms of political–military relations and their consequences in the Arab Spring by drawing on evidence from Syria, Egypt, and Tunisia
