No full textHeptranchias perlo (Bonnaterre, 1788) Sharpnose Sevengill Shark Squalus perlo Bonnaterre, 1788: 10. Holotype: unknown. Type locality: “La Méditerranée” [Mediterranean Sea]. Local synonymy: Heptranchias cinereus: Duméril, 1865: 437, pl. 4.? Heptranchis pectorosus: Barnard, 1925: 21, fig. 1, pl. 1 (in part, teeth appear to be H. perlo).

South Africa voucher material: SAIAB 6064, SAIAB 6246 [former ORI 453], SAIAB 6255, SAIAB 189030, SAIAB 193573, SAIAB 201757. Ebert (1990) examined numerous South African specimens, many of which are now in the fish collection (uncatalogued) at SAM. South Africa distribution: Cape Agulhas (WC) to the KZN border with Mozambique. Remarks: The species is most common off KZN, but individuals have been taken during survey cruises at least as far west as Cape Agulhas (WC). Early records of this species may have been misidentified with its larger congener (N. cepedianus), which mostly occurs in Cape waters. Barnard (1925: fig. 1, pl. 1) illustrates a sevengill shark that appears to be Notorynchus cepedianus, but the associated teeth are more consistent with those of H. perlo. Conservation status: NT (2020). Genus Hexanchus Rafinesque, 1810a Sixgill Sharks Hexanchus Rafinesque, 1810a: 14. Type species: “ Squalus griseus Lacépède ”, by original designation, a junior synonym of Squalus griseus Bonnaterre, 1788.Published as part of Ebert, David A., Wintner, Sabine P. & Kyne, Peter M., 2021, An annotated checklist of the chondrichthyans of South Africa, pp. 1-127 in Zootaxa 4947 (1) on page 18, DOI: 10.11646/zootaxa.4947.1.1, http://zenodo.org/record/461456
Determining military expenditures: arms races and spill-over effects in cross-section and panel data
No full textThis paper considers the determinants of military spending, building on an emerging literature that estimates military expenditure demand functions in cross-section and panel data, incorporating ‘arms-race’ type effects. It updates Dunne and Perlo-Freeman (2003b) using the SIPRI military expenditure database for the period 1988-2003, finding broadly similar results. It also shows differences in results across panel methods, particularly the within and between estimates and illustrates the importance of recognising and modelling dynamic processes within panel data. Heterogeneity is also found to be an important issue and when countries are broken up into groups on the basis of per capita income there is no obvious systematic pattern in the results. This is seen to imply that the demand for military spending, even between two mutually hostile powers, may depend on the whole nature of the relationship between them (and other countries and events in the region), and not simply Richardsonian action-reaction patterns

Hepranchias perlo
No full text<i>Hepranchias perlo</i> <p> TL ranged between 27 and 117 cm for males and between 20 and 124 cm for females. Common TL ranged from 60 to 100 cm for males and from 55 to 100 cm for females. <i>H. perlo</i> was presented in all months through year except February. Percentage of females catches was 53.2%. There was a significant difference between caught seasons (X 2 = 16.400, P = 0.001), peak of season landing was in spring (Fig. 2b) with a high percentage of juveniles (Fig. 3b). [17] reported that males and females of <i>H. perlo</i> maturing at 81 cm TL and 97 cm TL, respectively in Syrian marine waters. Therefore, about 50% of males and 74% of females were immature of catches (Fig. 4b).</p>Published as part of <i>Alkusairy, Hasan & Saad, Adib, 2018, Species Composition, Diversity and Length Frequency of By-Catch Sharks from the Syrian Coast, pp. 11-21 in International Journal of Research Studies in Zoology 4 (1)</i> on page 15, DOI: 10.20431/2454-941X.0401003, <a href="http://zenodo.org/record/10830731">http://zenodo.org/record/10830731</a>

Heptranchias perlo Bonnaterre 1788
No full textHeptranchias perlo (Bonnaterre, 1788) Type locality: France, northwestern Mediterranean Sea. The three Taiwanese samples included in this analysis formed a single cluster with another sample (GN 978) also from Taiwan (Supplementary Material 1). They represent a very small component of the circumglobal distribution of this species (Supplementary Material 1).Published as part of Straube, Nicolas, White, William T., Ho, Hsuan-Ching, Rochel, Elisabeth, Corrigan, Shannon, Li, Chenhong & Naylor, Gavin J.
