  • Fungi commonly encountered on monocotyledonous substrates were evaluated for their in vitro ability to produce enzymes involved in lignocellulose breakdown. Most were capable of structural polysac-charide utilization, but few produced enzymes associated with lignin breakdown. None of the mono-cotyledon-inhabiting fungi produced reactions as strongly as wood decay fungi.

  • The present note provides an overview of the three succeeding scientific papers, which gives an insight about the multidisciplinary studies and opinion on Biodiversity. These three papers are based on the seminar series of biodiversity organized by the department of life science, Hanyang University during 2011~2013.

  • Over five thousand higher fungal specimens were collected from 32 forest areas of Chungcheong and Gyeongsang province from 2012 to 2013. We obtained 513 strains and 3,120 ITS sequences. Mushrooms were first identified with macro- and micro-scopic characters, and their identification was confirmed on the basis of ITS sequences. Voucher specimens were designated for each species found in Korea. Construction of DNA barcoding Database is currently underway with sequences of 409 species. During the development of the database, some new species were recognized, along with several Korean new records. When the system has been completed, it will provide essential molecular information for metagenomic and phylogenetic researches for higher fungi.

  • An anisogammarid amphipod, Eogammarus possjeticus (Tzvetkova, 1967), is newly recorded from Jindo Island, Korea, with a detailed description and illustrations. The species belonging to the genus Eogammarus are sharing several plesiomorphic characteristics, so they are similar to each other. However, Eogammarus possjeticus can be discriminated from congeners by the following characters combined: appendages are not fossorial, setations of antennae are weak, and the number and position of robust setae on pleonal epimera, urosomes, and telson are different from its congeners. This is the first record of the genus Eogammarus Birstein, 1933 from Korean waters.

  • Calamus andamanicus Kurz is one of the commercially important solitary rattans endemic to Andaman and Nicobar islands. The habitat suitability modeling program, MaxEnt, was used to predict the potential ecological niches of this species, based on bioclimatic variables. The study revealed high potential distribution of C. andamanicus across both Andaman and Nicobar islands. Of the 33 spatially unique points, 21 points were recorded from South and North Andamans and 12 from Great Nicobar Islands. The islands like Little Andaman, North Sentinel, Little Nicobar, Tllangchong, Teressa were also predicted positive even though this rattan is not recorded from these islands. Mean diurnal range, higher precipitation in the wettest month of the year, annual precipitation and precipitation in the driest month are the main predictors of this species distribution.

  • We report the first occurrence of a tailless Girella leonina, collected from Jeju Island, Korea, in July 2016. This specimen has 10 scales below the median spinous portion of the dorsal fin, a black posterior margin of the operculum, and no pale vertical band on the body, and is therefore similar to the normal species, except that it has no caudal peduncle or caudal fin. The posterior parts of the dorsal and anal fins are gathered vertically at the posterior end of the body. A radiograph indicates that this abnormal specimen is lacking the vertebrae after vertebra 20.
