论《孽海花》中晚清士人的“卖直”

“卖直”由古代谏官制度发展变异而来,谏议的场所由朝堂之上转换到朝堂之外的士人之间,并且在儒家传统经世致用观念与晚清科举制度影响下,在西方列强入侵的刺激下兴盛起来,成为一种奇特的政治话语表达方式。《孽海花》一方面注意到“卖直”可以启发民众思想、开启民智,还能够展现出晚清士人关注时政的热情和对民族未来发展的关切;另一方面,也对一些士人的荒诞行径给予谴责。     

Living planktonic foraminifera from the northwestern Pacific Ocean:SSU rDNA sequences and their paleoceanographic significance

Living planktonic foraminifera(PF)samples from the Okinawa Trough of the northwestern Pacific Ocean were taken for DNA analysis.The SSU rDNA sequences of two PF species,Globigerina sp.and Pulleniatina obliquiloculata collected at Station WP01,were obtained and compared with those from the southwestern Pacific Ocean.Only small differences(<0.7%—1.2% for P. obliquiloculata,and 0.3% for Globigerina sp.)were found between samples from the north-and south-western Pacific Ocean areas and this molecular evidence supported that these micropaleontological species are the same species,which implies that the West Pacific Ocean circulation system influences the planktonic foraminiferal gene communication.     

Relating abundance of purpleback flying squid Sthenoteuthis oualaniensis (Cephalopoda: Ommastrephidae) to environmental parameters using GIS and GAM in south-eastern Arabian Sea

The distribution pattern of purpleback flying squid and the relationship between its abundance and environmental variables in the south-eastern Arabian Sea were analysed using a geographical information system (GIS) and a generalised additive model (GAM). Highest abundances were observed during December and January within 10 and 13°N and 71 and 72°E around the Lakshadweep Islands. The mean abundance in the area was 4.21 tonnes/km² and the maximum sustainable yield (MSY) was estimated as 0.63 million tonnes. GAM indicated that very high squid abundance was associated with low values of dissolved oxygen (6.01–6.27 mg/L), sea surface temperature (28.03–28.62°C), pH (7.75–8.56), salinity (30.42–34.48 psu), chlorophyll-a (0.4–0.6 mg/m³), zooplankton biomass (0.23–0.64 mL/m³), and shallow 20°C isotherm (101.2–134.7 m) and mixed layer depth (17.8–29.8 m). As a carnivore from paralarval stages, S. oualaniensis depends on secondary and tertiary production to sustain its population for which primary production is used up. In the tropical Arabian Sea where temperature differences are not so pronounced, S. oualaniensis distribution was found to be related to a low but very narrow sea surface temperature (SST) band. There is sufficient fishable biomass in the area to possibly launch a new targeted oceanic squid fishery from the western seaboard of India.

Biogeography of spiders (Araneae: Arachnida) on the islands of the Southern Ocean

The araneofauna of the extreme Southern Hemisphere is highly impoverished and disharmonic. Four dead anthropogenic immigrant spiders have been collected from Antarctica while only 115 verified species from 26 families are reported on the islands of the Southern Ocean. Cluster analysis of the verified Southern Ocean species distribution data identifies a weak, but distinct, Neotropical/South Atlantic association together with robust South Indian and South Pacific biogeographic clusters. These groupings, largely attributed to vicariance and/or endemism, contain little evidence of post-Pleistocene dispersal. Indeed the 14 records of anthropogenic origin suggest that the pace of recent human-mediated introduction has been at least 30 times more rapid than that of Holocene natural dispersal.     

On the South American species of the genus Meridiosignum (Crustacea: Isopoda: Asellota: Paramunnidae)

Meridiosignum undulatum n. sp. and M. disparitergum n. sp. are described from off the Río de la Plata estuary. These two new species are easily distinguished from other members of the genus Meridiosignum in having the lateral margins of pereonites 2 and 3 bilobed (the concavity is much more pronounced in M. disparitergum), and those of pereonite 4 produced into a single process. The terminal male instar of Meridiosignum menziesi (Winkler, 1994 Winkler, H. 1994. Paramunnidae (Crustacea: Isopoda: Asellota) from the Magellan Strait.. Zool J Linn Soc., 110: 243–296. [Crossref] , [Google Scholar]) is described, and this species is herein reported from the Beagle Channel and Puerto Deseado. All the species currently placed in Meridiosignum were found in shallow waters in the southern hemisphere, M. undulatum n. sp. and M. disparitergum n. sp. being the species recorded at the greatest depth (129 m).     

A preliminary account of the shallow-water echinoderms of Rodrigues,Mauritius, western Indian Ocean

Collections of echinoderms were made from the intertidal, lagoon and reef slopes of Rodrigues over a period of 3 weeks in September to October, 2001. A total of 74 species are reported here, including three species of Crinoidea, 10 species of Asteroidea, 17 species of Ophiuroidea, 15 species of Echinoidea and 29 species of Holothurioidea. These findings include 10 new records for the Mascarene Islands (Réunion, Mauritius and Rodrigues), four species (two in the asteroid genus ‘Asterina’, one in the ophiuroid genus Amphioplus and one species in the holothurioid genus Actinopyga) that remain unnamed due to the need to clarify unresolved taxonomic issues, and one species of crinoid which could not be identified because only the distal parts of four arms were collected. In the dendrochirotid holothurioid family Psolidae, the little-known species Psolus appendiculatus (de Blainville) 1821 Blainville, H. M. de. 1821. Holothuries. Dictionaire des Sciences Naturelles, 21: 310–319.  [Google Scholar], P. boholensis Semper, 1868 and P. complanatus Semper, 1868 are referred to the genus Psolidium Ludwig, 1887. Despite its seniority, P. appendiculatus is treated as a (senior) synonym of the better known and described species Psolidium ornatum (Perrier, 1893). In the dendrochirotid holothurioid family Phyllophoridae, Thyonidiella cherbonnieri nom. nov. is proposed for misidentified specimens of Semperiella tenera (Ludwig, 1875) in the western Indian Ocean, and Semperiella Heding and Panning, 1954 Heding, S. G and Panning, A. 1954. Phyllophoridae. Eine bearbeitung der polytentaculaten dendrochiroten Holothurien des zoologischen Museums in Kopenhagen. Spolia Zoologica Musei Hauniensis, 13: 7–209, 102 figures [Google Scholar] is reduced to the synonymy of Thyonidiella Heding and Panning, 1954 Heding, S. G and Panning, A. 1954. Phyllophoridae. Eine bearbeitung der polytentaculaten dendrochiroten Holothurien des zoologischen Museums in Kopenhagen. Spolia Zoologica Musei Hauniensis, 13: 7–209, 102 figures [Google Scholar]. In the apodid holothurioid family Chiridotidae the species Chiridota eximia Haacke, 1880 Haacke W 1880 Holothurien in K. A. Möbius and F. Richter (eds) Beitrage zur Meeresfauna der Insel Mauritius und des Seychelles (Berlin: Gustav Fischer), pp.?46–48  [Google Scholar] is reduced to the synonymy of C. rigida Semper, 1868.

Given the small size of the area of shallow water around Rodrigues that has been sampled, the relatively small range of marine habitats present and the geographic isolation, this is an impressive diversity. The biogeography of the 69 identified species of Rodrigues is discussed.     

Why are there so few “far southern” myriapods?

There are no extant Antarctic myriapods. The “far southern” islands south of latitude 45° S together with the isolated (south Atlantic) Tristan da Cunha, Gough, (south Indian) St Paul, Amsterdam and (south Pacific) Chatham islands (at 37 to 44° S), harbour only 33 native, introduced and partly identified taxa, including 17 Chilopoda, 11 Diplopoda, two Pauropoda and four Symphyla. The myriapods confined to the extreme edge of the Southern Ocean are entirely derived from pre-glacial Tertiary relicts or post-glacial anthropogenic introductions and show no evidence of co-occurring sibling taxa. This unusual distribution pattern provides a useful “no dispersal/no speciation” benchmark that can be applied to other far-southern non-marine invertebrates where the distinction between pre-glacial and post-glacial endemic taxa is not so clearly defined.
