The levels of activities of amylase, lipase and trypsin in both the pancreatic tissue and serum of 18 species of vertebrate animals were measured and enzymologically compared with each other. 1) The value of amylase in the pancreas of experimental mammalia has been found decreasing in the order pig, rat, dog, cat, rabbit and cow; that of pancreatic lipase has been found decreasing in the order of pig, dog, cat, rat, rabbit and cow; and that of trypsin has been found decreasing in the order of pig, cow, dog, rat, rabbit. Thus the value of all the above three kinds of enzymes were observed highest in pig, but in cow amylase and lipase were observed lowest while trypsin were observed considerably high. 2) In view of diets, the comparatively high values of pancreatic enzyme were observed in the ommivorous animals such as pig, rat, dog, while the values observed low in the herbivorous animals, such as cow and rabbit. 3) In the bovine, the values were observed moderately high except lipase which were found comparatively low. 4) In the Reptilia and Amphibia such a mud turttle and frog, the values were shown in similar measure with each other, that is, the pancreatic amylase and trypsin were observed considerably high while the lipase was found low. 5) In the species of Reptilia such as a viper and snake, the activities of pancreatic enzymes were not detected. But in the tissue of liver, stomach, activities of the enzymes were found considerably high. Lacertilia animals such as lizard the values of pancreatic enzymes were little observed. 6) In the fish in which the pancreatic tissue is scattered in the liver, the pancreatic enzymes were found in the liver tissue considerably higher than in the other tissues but lower than in the warm-blooded animals, especially the lipase was lower. 7) In generally the values of serum amylase and lipase were observed higher than those of man; and even in the cold-blooded animals in which the values of pancreatic enzymes were shown low or none, the values were also observed high. 8) The above three kinds of pancreatic enzyme values of those experimental animals have shown a tendency of higher degree in higher taxa than in lower taxa according to taxonomical order. 9) In view of tissue, the pancreatic cell was observed large in the mammalian animals such as rat and pig and cytoplasm was also abundantly contained in the acinous cell; and the bovine and the snake haave the pancreatic cells of the similar rosette form the comparatively large acinous cells of long rhombic form in the comparatively large acinous cells of long rhombic form in which the spindle shaped neucleus and the abundant cytoplasm were contained. In the fish the pancreatic cell were found scattered in the liver in which the very large pancreatic islet were found.

본 연구에서는 멸종위기 야생생물 II급이자 천연기념물(453호)인 한국산 남생이 Mauremys reevesii가 집단으로 발견된 경북 경주시 내 저수지의 특성을 파악하였다. 또한 서식지 내에서 남생이의 생존에 직 간접으로 위협이 되는 생물 및 비생물적 요인들을 조사하였다. 남생이가 집단으로 발견된 지역은 농업용으로 관리 중인 저수지이다. 서식지 주변에는 수몰나무 지대, 석축, 산림, 갈대밭, 농경지(논)가 형성되어 있었다. 저수지 내 모든 남생이들은 저수지 북면에 형성되어 있는 수몰나무지에서만 발견되었다. 2018년 5월 10일과 8월 9일에 걸친 현지 조사에서 발견된 남생이의 수는 각각 28 개체와 21 개체였다. 남생이에게 위협이 되는 붉은귀거북과 황소개구리가 서식지 주변에서 다수 발견되었다. 문화재 발굴 작업, 화학 비료 그리고 생활 쓰레기가 저수지 곳곳에서 발견되었으며, 이는 남생이에게 큰 위협요인이 될 것으로 추정된다. 당해 연도 태어난 개체들은 확인되지 않았지만 아성체들이 다수 발견된 것을 고려하면 자연 번식이 충분히 이루어지고 있는 것으로 추정된다. 하지만 경쟁종인 붉은귀거북의 아성체 역시 발견되었기 때문에 남생이에게는 지속적인 문제가 될 수 있다. 연구의 결과를 종합하면, 국내 최대 규모의 남생이 개체군을 보호하기 위한 방법으로는 서식지 내 보전 방법이 적극적으로 고려되어야 할 것으로 판단된다.

Recent years, nationwide projects for ecological restoration are implemented with emerging issues on the stream ecosystem. In order to enhance effectiveness of the ecosystem restoration and reduce negative impact, the appraisal of effectiveness through the follow-up monitoring and the adaptive management process are executed in consecutive phase. In this study, planning phase, monitoring and adaptive management in Hakui stream which is part of An Yang stream restoration project is introduced as representative ongoing case of effective adaptive management. The aim of this study is to verify the adaptive management process and suggest direction of effective restoration. Restoration project of Hakui stream resulted in increasing number and diversity of species (vegetation, fish, bird, invertbrates, amphibian and reptilia) according to monitoring from 2004 to 2013, and enhancing natural river landscape by evaluation of river naturalness among 2001(before restoration), 2007 (after), 2015 (recent). However, excessive vegetation expansion or sediment deposition on channel over time caused unexpected results such as terrestrialization or degradation of habitats. Adaptive management action such as removing disturbance species (Humulus japonicus)(2007), coppicing willow (2007), release of march snail (2007), creation of wetland (2014) were implemented based on monitoring results. And then appraisal of management action was discussed.

In this study, we have evaluated the physical characteristics of neonate, female, and male Mongolian racerunners (Eremias argus) and determined the age structure of a population of the species in a field located in Taean-gun, Chungnam, South Korea. The physical parameters of females and males, including snout-vent length (SVL), head length, head width, and body mass were found to be significantly interrelated. Male Mongolian racerunners exhibited significantly longer heads than the females, but other physical parameters, such as SVL, head width, and body mass did not differ between the female and male specimens. In the study population, the females ranged in age from two to eleven years old and the males ranged between two to eight years of age. The number of females and males, when separated into different age classes, did not differ within each age class. Male Mongolian racerunners evidenced greater SVL growth coefficients than the females, but asymptotic SVL did not differ between the females and males.

In Korea ,little attention was paid to chiggers until 1950 so only to reports on four species of chiggers were pulished before Korean War. Since 1950 (beginning of Korean War), a marked progress in the study of chiggers has been made in connection with investigations of Epidemic hemorrhagic fever occurring among the United Nations troops which was suspected as a chigger-borne infectious disease and the first report of tsutsugamushi disease in Korea called natives attention to chiggers as the vector mites of this newly known disease in Korea. This paper is mostly based on specimens of author's collections from 3269 Rodentia Insectivora, 9 Chiroptera, 24 Aves , 35 Amphibia and 3 Reptilia during the time from December 1955 to December 1956 but four species were introduced here from works of others . There are reported here five species of chiggers previously known only out of Korea and a new species also. This new species was collected by author but Lipovsky informed his colleague had collected the same one in Korea and they would publish it as new one in near future. This is the reason of describing the new species without specific name . Of course, this paper is incomplete in view of the geographic distribution, seosonal change and host relation etc, but will serve as a brief summary of the chiggers fauna of Korea up to the present. This species described here are as follows : Gahrliepia brennani var. ventralis Neoschongastia posekanyi Euschongastia kigtajimai Euschongastia miyagawai Euschongastia koreaensis Trombicula nagayoi Trombicula japonica Trombicula pomeranzevi Trombicula mitamurai Trombicula tamiyai Trombicula palpalis Trombicula orientalis Trombicula pallida Trombicula scutellaris Trobmicula miotis Trombicula hiranumai Trombicula sp. Trombicula hiranumai Trombicula sp. Trombicula subintermedius Shunsennia tarsalis . Euschongastia ikaoensis . Trombicula koomori Trombicul subakanushi

This study was conducted to investigate the movement and home range of the red-tongued viper snake (Gloydius ussuriensis) from June 2006 to June 2009. This snake species inhabits an islet on Jeju Island, Gapado. A total of 132 individual snakes were marked during the study. Among the marked individuals, the number of snakes recaptured more than once was 22 (16.8 %) and the number of individuals recaptured more than twice was eight (6.1 %), indicating a relatively low recapture rate. The durations from capture to recapture varied from 1 to 710 days. However, the capture points were not much different, indicating that the moved distance of snakes and the interval between capture-recapture were not correlated. The home ranges of the Red-tongued viper snakes calculated from data of the snakes which were captured more than three times using the MCP(minimum convex polygon) method were $8{\sim}167m^2(64.0{\pm}57.0m^2)$, suggesting that this snake is relatively sedentary. Home range size differences between female ($Mean=62.0m^2$) and male ($Mean=66.0m^2$) snakes were not significant. In the red-tongued viper population of Gapado, there was no statistically significant relationship between body size and home range size although it was positively correlated (r=0.675). Our results provide valuable data to understand life patterns of the red-tongued viper snakes and will be useful when conducting further ecological studies on other snake species.

The red-tongue viper(Gloydius ussuriensis) is one of only three species of the genus Gloydius found in South Korea. Gloydius ussuriensis has a narrow activity radius and is distributed nationwide, and this species was reported to have the largest population among the Korean species in genus Gloydius. Preliminary results of a phylogenetic analysis using part of the mitochondrial DNA indicated that domestic G. ussuriensis is not comprised of monophyletic groups, and morphological analysis showed differences between domestic populations. In this study, we developed 17 microsatellites for the analysis of G. ussuriensis genetic diversity based on these characteristics. These microsatellites were developed using six multiplex panels, which could be employed to validate 80 G. ussuriensis specimens from different geographical regions in South Korea. The average number of alleles per locus was 12.2 and ranged from 4 to 25 alleles; the observed heterozygosity ranged from 0.238 to 0.950 and the expected heterozygosity ranged from 0.213 to 0.933. As a result of assessing four inland populations, a high level of genetic diversity was confirmed. These newly developed markers will be useful for further studies on the population structure and evolutionary history of the G. ussuriensis.

생물다양성은 생존하는 유기체들의 변이성으로 정의하며 지구상의 생물의 다양성과 생태계를 구성하는 복잡한 상호작용을 일컫는다. 본 연구는 합천군 덕진천에 서식하는 동물의 종조성과 다양성을 공간적 시간적 양상으로 실시하였다. 2016년 시즌에 동정된 포유류, 연골어류, 경골어류, 조류, 양서류, 파충류, 어류 종의 수는 55분류군이었다. 포유류의 Berger-Parker's index (BPI)는 0.233(지점 A)에서 0.333(지점 D)로 나타났다. 포유류와 조류에 대한 Shannon-Weaver index (H')와 두 다른 다양성 척도(N1과 N2)는 상류지역이 하류 지역보다 높았다. 동물 분류군에 대한 ${\beta}$-다양성은 어류 0.229에서 무척추동물 0.339까지 나타났다. 동물종에 대한 풍부도 지수는 지점과 시기에 따라 변화가 있었다. 지점 A는 포유류, 조류, 양서/파충류에서 높은 풍부도를 나타내었다. 비록 다섯 동물 강에 대한 풍부도 지수(R1, R2)가 시즌 별로 다르지만 유의성을 나타내지는 않았다. 균등도 지수(E1-E5) 역시 시즌 별로 다르지만 유의성을 나타내지는 않았다.

이 연구에서는 중학생(N=300)을 대상으로 질문지와 면담을 통해 주요 동물의 분류에 관한 오류와 그 이유가 되는 사고 내용을 조사하였다. 연구결과, 척추동물과 무척추동물로 분류하는데 있어서 뱀(31.7%), 새우(28.3%), 거북이(25.6%), 개구리(24.7%), 불가사리(10.7%) 등의 순서로 오류의 빈도가 높았다. 이러한 오류의 이유는 각 동물의 운동 특성과 외형적 특성에 따른 직관적 사고, 다른 동물의 특성에 비유하여 잘못된 유추를 하는 것, 각 동물의 척추 관찰 부족 때문인 것으로 나타났다. 또한 척추동물의 하위분류군을 구분함에 있어서 '도롱뇽은 파충류(45.3%), 거북이는 양서류(40.3%)'로 대안개념을 갖는 오류가 높게 나타났다. 그 이유는 분류 용어의 모호함으로 인한 혼동과 각 동물의 생리 생태적 특성을 분류 기준의 특성에 연계시키지 못하는 것에 있었다. 박쥐, 고래, 펭귄의 분류에서는 사회 문화적 요인이 오류의 빈도에 영향을 주었다. 동물 분류의 교수 학습이 암기 위주의 주입식보다는 관찰을 통한 분류 기준의 특성을 탐색하는 활동의 지도가 필요하다.
