Additional Records of Folliculinids (Protozoa) m Hawaiil
نویسنده
چکیده
THUS FAR, only three species of folliculinids have been recorded for Hawaii: Andrews ( 1944) assigned folliculinids from Kaena Point to Parafolliculina annulata [reassigned by Hadzi (1951) to Halofolliculina annulata (Andrews)]; and Matthews (1953) assigned folliculinids from Waimanalo Creek to Metafolliculina andrewsi Hadzi and those from the Hawaii Marine Laboratory to Lagotia simplex Dons. This paper records two additional species taken on glass-plate panels (vid. Moebius, 1887). Each panel (Fig. 1) resembled a large open slide box and contained six 8 cm X 10 cm unetched glass plates. These panels, with floats and anchors adjusted, were placed in the dock lagoon, Hawaii Marine Laboratory, where they floated freely approximately a meter above the sand and coral bottom. The first plate was removed and examined May 16, having been submerged 1 week; the second plate was examined May 23, having been submerged 2 weeks, and so on, until all plates had been removed. The cycle was then repeated. Although pelogloea formation (Fox et aI., 1952: 30) and sequential fouling were beyond the scope of this study, both were noted. Whereas some sedentary polychaetes and folliculinids attached to the plates' upper surface, most fouling organisms adhered to the under surface. Noteworthy, too, is the fact that, although Metafolliculina andrewsi was present on all plates, Lagotia simplex and Halofolliculina annulata were present on none. During May, June, and July, attached, fully extended folliculinids were abundant, and from this material all measurements were made. Of these, lorica (test) measurements were usually easy; body measurements rarely so. This was primarily because of body contractility which, while it seldom affected the size and shape of the

Efficacy of Mimosa Tenuiflora extract on growth of Leishmania protozoa in vitro
Background and aim: Leishmaniasis is a zoonotic disease with wide clinical diversity caused by protozoan parasite belonging to the genus of Leishmania. Treatment of human leishmaniases are still based on pentavalent antimonials but their toxicity and emerging resistance are problematic. This study was performed to assess the effect of Mimosa tenuiflora extract on L. tropica promastigotes ...
متن کاملM M m K Queue With Additional Servers and Discouragement (RESEARCH NOTE)
Waiting in long queue is undesirable due to which in some practical situations customers become impatient and leave the system. In such cases providing additional servers can reduce long queue. This investigation deals with multi-server queueing system with additional servers and discouragement. The customers arrive in poisson fashion and are served exponentially by a pool of permanent and addi...

متن کاملM m m Queue with Balking, Reneging and Additional Servers
In this paper, we consider a multi-server queuing system in which additional servers are allowed for a longer queue to reduce the customer’s balking and reneging behavior. The customers are assumed to arrive in Poisson fashion and their service- times follow exponential distribution. The number of servers in long run depends on the queue-length. We obtain equilibrium queue size distribution. Th...
متن کاملInvestigation on bioavailability of rumen bacterial and protozoal phosphorus using a chick-model
Ruminal bacteria and protozoa provide excellent organic phosphorus (P) sources for the host animal. This experiment was conducted to compare the bioavailability of bacterial and protozoal P in comparison with that of dicalcium phosphate (DCP) as a reference phosphorus source. Bacteria and protozoa were isolated from the rumen contents of dairy cows and the chick-model was used to determine the ...
