FIVE RED TIDE SPECIES IN GENUS PROROCENTRUM INCLUDING THE DESCRIPTION OF PROROCENTRUM DONGHAIENSE LU SP. NOV. FROM THE EAST CHINA SEA 总被引：22，自引：0，他引：22
A new planktonic dinoflagellate, Prorocentrum donghaiense I_a sp. nov., is described in the present paper. The water sample was collected from the Changjiang Estuary, the East China Sea. The species identification is based on shape, size, surface micro-morphology, ornamentation of thecal plates and the architecture of the pel‘iflagellar area and the intercalary bands as seen by fight and scanning electron microscope. Prorocentrum donghaiense Lu sp. nov. is compared with other prorocentrum species with respect to morphological characteristics and bloom behavior. It is not known whether Prorocentrum donghaiense Lu sp. nov produces phycotoxins like some other Prorocentrum species. Four other red tide species in the family Prorocentraceae (Dinophyceae), namely P. balticum, P. minimum, P.micans, P. triestinum, were examined and identified by light and scanning electron microscope. They have been recorded as bloom-forming species. Some aggregates of Prorocentrum are observed at the end of blooms. An event of strong discoloration caused by P. donghaiense could be detected by satellite sensor in the East China Sea in the late spring, of 1995. 相似文献

A new muricid gastropod species,L ataxiena lutescena sp. nov.,is described and illustrated. The new species was recognized during reidentification of the Muricidae collection in the Marine Biological Museum,Chinese Academy of Sciences,Qingdao. The specimens of the new species were collected from the East and South China Seas off Fujian,Guangdong,and Hainan Provinces. Lataxiena lutescena sp. nov. is similar to Lataxiena blosvillei(Deshayes,1832) in general shape,but can be distinguished from the latter by the shell sculpture and radular characteristics. Lataxiena lutescena sp. nov. also resembles Lataxiena bombayana(Melvill,1893),but differs from that species in the shell shape and anal notches and in lacking short spines on the shell. 相似文献

A new species of bubblegum coral,Paragorgia papillata sp.nov.,discovered from a seamount located on the Caroline Ridge at the water depth of 858 m,is studied using morphological and molecular approaches.The new gorgonian is white-colored,uniplanar with prominent autozooids,and measures about670-mm high and 690-mm wide.The genetic distance and phylogenetic analysis showed that P.papillata sp.nov.was closely related to P.coralloides Bayer,1993,but the former differs morphologically from the latter by its prominent calyces(diameter 2.0-4.0 mm and height 1.5-3.0 mm vs.both diameter and height about 1 mm),white cortex(vs.pink),regular 8-radiates in surface cortex(vs.mostly 8-radiate derived globular radiates) and highly ornate medullar spindles(length 185-400 μm vs.no more than 150 μm).P.papillata sp.nov.is the third known white-colored species of the genus,and the fifth species found in the tropical Western Pacific. 相似文献

It is over 110 years since the term Mass Elevation Effect(MEE) was proposed by A. D. Quervain in 1904. The quantitative study of MEE has been explored in the Tibetan Plateau in recent years; however, the spatial distribution of MEE and its impact on the ecological pattern of the plateau are seldom known. In this study, we used a new method to estimate MEE in different regions of the plateau, and, then analyzed the distribution pattern of MEE, and the relationships among MEE, climate, and the altitudinal distribution of timberlines and snowlines in the Plateau. The main results are as follows:(1) The spatial distribution of MEE in the Tibetan Plateau roughly takes on an eccentric ellipse in northwestsoutheast trend. The Chang Tang Plateau and the middle part of the Kunlun Mountains are the core area of MEE, where occurs the highest MEE of above 11℃; and MEE tends to decreases from this core area northwestward, northeastward and southward;(2) The distance away from the core zone of the plateau is also a very important factor for MEE magnitude, because MEE is obviously higher in the interior than in the exterior of the plateau even with similar mountain base elevation(MBE).(3) The impacts of MEE on the altitudinal distribution of timberlines and snowlines are similar, i.e., the higher the MEE, the higher timberlines and snowlines. The highest timberline(4600–4800 m) appears in the lakes and basins north of the Himalayas and in the upper and middle reach valleys of the Yarlung Zangbo River, where the estimated MEE is 10.2822℃–10.6904℃. The highest snowline(6000–6200 m) occurs in the southwest of the Chang Tang Plateau, where the estimated MEE is 11.2059°C–11.5488℃. 相似文献

A new species of ciliatesHemiophrys polymicronuclei sp. nov. from Donghu Lake is described. It is characterized by its colorless to yellowish, soft, flat and spindle-shaped
body with four micronuclei. The right side of the body is a little more convex than the left side, and more transparent at
both anterior and posterior ends. Its slit-like cytostome accounts for 1/4 of the body length on the left side without any
trichocyst. There are two rows of trichites near the right anterior end, 6–8 straight bristles on the pellicle opposite the
cytostome, 23–25 rows of kinetides on the right side of the body, two ellipsoid macronuclei and many contractile vacuoles
in the cytoplasm. 相似文献
