  • 거문도 연안해역에서 채집된 말쥐치(Thamnaconus modestus) 172개체의 식성을 분석하였다. 말쥐치의 표준체장 (SL)은 16~39 cm 범위였다. 말쥐치의 위내용물을 분석한 결과 곤봉바다맨드라미류 (Neptheidae), 해조류 (Algae), 만각류 (Thoracica), 복족류 (Gastropoda)와 같은 저서생물 (benthos)을 주로 섭식하는 잡식성(Omnivore)어류였으며, 그 외에 해면류 (Desm ospongia), 단각류 (Amphipoda) 등도 섭식하였지만 그 양은 많지 않았다. 말쥐치는 섭식형태와 특성을 분석한 결과, 다양한 먹이생물을 섭식하는 섭식일반종 (generalist)이었다. 체장 33 cm 이상의 체장군을 제외한 전 체장군에서는 곤봉바다맨드라미류와 해조류의 섭식율이 높았다. 체장 33 cm 이상의 체장군에서는 만각류의 섭식율은 증가 하였으나, 곤봉바다맨드라미류의 섭식율은 감소하였다. 체장 33 cm 이상의 개체군에서는 0.34의 값을 보여 낮은 중복도를 나타냈으며, 그 외의 체장군에서는 0.6 이상의 값을 보여, 비교적 높은 중복도를 보였다.

  • Background: Stingless bee propolis is a popular traditional folk medicine and has been employed since ancient times. This study aimed to evaluate the antinociceptive activities of the chemical constituents of aqueous propolis extract (APE) collected by Trigona thoracica in a nociceptive model in mice. Methods: The identification of chemical constituents of APE was performed using high-performance liquid chromatography (HPLC). Ninety-six male Swiss mice were administered APE (400 mg/kg, 1,000 mg/kg, and 2,000 mg/kg) before developing nociceptive pain models. Then, the antinociceptive properties of each APE dose were evaluated in acetic acid-induced abdominal constriction, hot plate test, and formalin-induced paw licking test. Administration of normal saline, acetylsalicylic acid (ASA, 100 mg/kg, orally), and morphine (5 mg/kg, intraperitoneally) were used for the experiments. Results: HPLC revealed that the APE from Trigona thoracica contained p-coumaric acid (R2 = 0.999) and caffeic acid (R2 = 0.998). Although all APE dosages showed inhibition of acetic acid-induced abdominal constriction, only 2,000 mg/kg was comparable to the result of ASA (68.7% vs. 73.3%, respectively). In the hot plate test, only 2,000 mg/kg of APE increased the latency time significantly compared to the control. In the formalin test, the durations of paw licking were significantly reduced at early and late phases in all APE groups with a decrease from 45.1% to 53.3%. Conclusions: APE from Trigona thoracica, containing p-coumaric acid and caffeic acid, exhibited antinociceptive effects, which supports its potential use in targeting the prevention or reversal of central and peripheral sensitization that may produce clinical pain conditions.

  • The whole mitochondrial genome (14,915 nt) of Pollicipes mitella (Crustacea, Maxillopoda, Cirripedia, Thoracica) was sequenced and characterized. It is the shortest of the 31 completely sequenced crustacean mitochondrial genomes, with the exception of a copepod Tigriopus japonicus (14,628 nt). It consists of the usual 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 1 relatively short non-coding region (294 nt). The thoracican cirripeds apart from Megabalanus volcano have the same arrangement of protein-coding genes as Limulus polypemus, but there are frequent tRNA gene translocations (at least 8). Some interesting translocation features that may be specific to the thoracican cirriped lineage are as follows: 1) trnK-trnQ lies between the control region and trnI, 2) trnA-trnE lies between trnN and trnS1, 3) trnP lies between ND4L and trnT, and 4) trnY-trnC lies between trnS2 and ND1. In P. mitella there are two trnL genes (L1 and L2) in the typical crustacean positions (ND1-L1-LrRNA and CO1-L2-CO2). The present result is compared and discussed with the other three cirriped mitochondrial genomes from one pedunculate (Pollicipes polymerus) and two sessiles (Tetraclita japonica and M. volcano) published so far. Mitochondrial protein phylogenies reconstructed by the BI and ML algorithms show that the thoracican Cirripedia is monophyletic (BPP 100/BP 100) and associated with Remipedia (BPP 98/BP 35). In addition, Oligostraca, including Ostracoda, Branchiura, and Pentastomida, is a monophyletic group (BPP 99/BP 68), and is basal to all the other examined arthropods. Remipedia + Cirripedia appears as an independent lineage within Arthropoda, apart from Thoracopoda (Malacostraca, Branchiopda, and Cephalocarida). The Thoracopoda is paraphyletic to Hexapoda. The present result suggests that the monophylies of Crustacea and Maxillopoda should be reconsidered.

  • Community structures and species composition in benthic crustacean around Oryukdo of Busan was investigated using a SCUBA diving in 2011. A total 115 species, 51 families, and 4 taxa were collected during the sampling periods. Species were included 52 species in amphipoda, 49 in decapoda, 8 in isopoda and 6 in thoracica. On cluster analysis, the benthic crustacea community was classified into three groups based on the species composition: group A occurred in spring, group B in autumn and winter and group C in summer. Species composition in benthic crustacean corresponded with the water temperature.

  • Sessile barnacle, Balanus trigonus Darwin, was collected from the intertidal rocks and the external shells of bivalve Mylius coruscus. The nauplius and cyprid larvae were cultured in a constant temperature cabinet at a temperature of $20^{\circ}C$ and a light regime of 14 h light and 10 h darkness. Larval development includes the six nauplius stages and a cyprid stage prior to settlement and metamorphosis to the young adult. Morphological characteristics including antennules, antennae and mandibles are described and illustrated. All nauplius larvae have trilobed labra typical in balanoides. The developmental time taken from newly hatched nauplius I to cyprid was $9\~13$ days and averaged 11 days.

  • Nauplii and cyprid la%ae were cultured in the laboratory at a temperature of 25'c of 33 parts per thousand. La%al development includes the six nauplius and a cyprn'dstages. Morphological characteristics such as antennules, antennae and mandibles as well as the general pattern of the thoracican Cirripedia are described and illustrated. All the nauplius larvae have trilobed labra which are typical in balanoides, with numerous slender hairs. It is possible to compare the setation of larva of Balanus kondakoui with those of B. albicostatus, B. amphitrr'te, 9. trigonus, B. uariegatus, and Chthamafus rhallengerl' by plotting of numerical setation of the antennae against the mandibles.
