The feeding ecology of marine pelagic copepods has been intensively studied since the 1910's. Recently, many new techniques, such as high-speed cinematography, deep-sea ROV, and SCUBA, have been introduced for direct observatios of their feeding behavior. These have clearly revealed that particle-feeders employ suspension feeding but not filter-feeding and that appendicularian houses are important food items for some pelagic calanoid, harpacticoid, and poecilostomatoid copepods. Particle-feeders commonly utilize microzooplankton such as ciliates and copepod nauplii and fecal pellets. Detritivory, strict selective predation, and gorging have been found exclusively in oceanic copepods. Five calanoid families Diaixidae, Parkiidae, Phaennidae, Scolecitrichidae, and Tharybidae with special sensory setae on the mouthparts and the poecilostomatoid Oncaea are considered to be adapted for feeding on detrital matter such as appendicularian houses. Some heterorhabdids probably inject a venom or anesthetic into prey animals to capture them. In the laboratory, predation on fish eggs and larvae by copepods, rejection of some dinoflagellates by calanoids, developmental inhibition of copepod eggs by feeding on some diatoms, and copepods' reactions to fecal pellets were demonstrated. Pelagic copepods constitute an assemblage of evolutionarily different groups. Among the 10 orders, calanoids supposedly first colonized the marine pelagic realm, and, at present, are most successfully adapted of any order to this environment by a wide variety of feeding mechanisms. They have developed a wide variety of feeding mechanisms. On the other hand, poecilostomatoids have secondarily become adapted to pelagic environments and are loosely associated with fish larvae and pelagic invertebrates, such as salps and appendicularians, for feeding. The calanoid family Heterorhabdidae consists of 2 particle-feeding, 3 carnivorous, and 2 intermediate genera. A phylogenetic analysis showed that the carnivores could have originated from the particle-feeders through the intermediate conditions, and that the mouthpart elements of the carnivores could be derived from those of the particle-feeders with modifications of the original elements and no addition of novel structures. Recent studies demonstrate that some copepods such as scolecitrichids and Oncaea can efficiently feed on nanoplankton trapped in appendicularian houses, and also suggest that suspension-feeders may transport diatom resting spores into the sea-bottom in the epipelagic zone and metals in the deep-sea bottoms through their feeding behavior, and that epipelagic carnivores may compete with fish larvae for copepod nauplii and dinoflagellates.

The Sata-dao group of graves with burial mound, where the excavations were carried out, is located in the urban area on the east side of Shōbara city in the northern part of Hiroshima Prefecture. The group was built between the end of the last third of the Middle Yayoi period (1st century BC) and the first third of the Late Yayoi period (1st century AD).A series of excavations yielded the following results: Sata-dao No. 1 and 2 are square-shaped ditch-enclosed slightly elevated burial precincts (hōkei shūkō bo); No. 3 is a grave with rectangular burial mound and four corner projections (yosumi tosshutsugata funkyū bo); No. 4 is also a grave with rectangular burial mound and four corner projections, but has subsequently been modified and altered into a square-shaped burial mound; No. 5 is a square-shaped ditch-enclosed slightly elevated burial precinct (hōkei shūkō bo), where on the inside of the ditch-enclosed space a grave pit was confirmed.Towards the end of the last third of the Middle Yayoi period after repeated burials of several individuals, the burial mound of the Sata-dao No. 3 grave was completed. At grave No. 4, which is from the same phase, in the lower strata of the burial mound the surface of the excavation of a grave pit could be confirmed. In other words, it became clear, that at the graves No. 3 and 4 with rectangular burial mound and four corner projections, grave pits were first excavated before the burial mound was finally taking shape. Then the deceased persons were buried within and thereafter the grave pits were backfilled with the soil of the pit excavation. The so repeated iterations of grave pit excavation, burial and backfilling gradually produced the mound. However, on the other hand at Sata-dao grave No.1 and 2 the burials took place after the earthworks of the mound were nearly completed.According to the results of the surveys, within the same group of graves one could confirm that the construction methods of the burial mounds changed: from the type, where the mound and the burial facilities are simultaneously constructed [co-occurrent progression type] of the end of the last third of the Middle Yayoi period to the type, where burial mound construction proceeds first ["mound first" type] of the first third of the Late Yayoi period. It became clear that is a rather rare group of graves with burial mound. This group is not only constructed during a relatively early stage of Yayoi period graves with burial mound, but also it became obvious that this is a very important site, if one is taking into consideration the development of construction methods of burial mounds of Yayoi period graves. Hereafter, for an understanding of the development of construction methods of burial mounds of Yayoi period graves the site is offering important insights.その他のタイトル:庄原市教育委員会発掘調査報告書第28冊本報告は広島大学大学院文学研究科考古学研究室と庄原市教育委員会が提携して推進している共同研究『佐田谷・佐田峠墳墓群の発掘調査』(研究代表者:古瀬清秀)および、『四隅突出型墳丘墓の発達に関する考古学的研究』と題する科学研究費補助金(基盤研究(C)、課題番号23520922〈研究代表者:野島 永〉)による調査研究の成果を掲載した。
