Introduction
Watching birds has widely altered my thoughts, career, and life. Led by birds, I got interested in ecology, introduced into population genetics, joined molecular ecology lab in Ewha, South Korea, and finally joined avian ecotoxicology lab in McGill, Canada. Currently, I am investigating the impact of environmental chemicals on avian gene expression.

The increasing application of RNA-seq to study non-model organisms demands easy-to-use and efficient bioinformatics tools to help researchers quickly uncover biological and functional insights from large datasets. Here, we present a unified software suite for processing, analyzing, and interpreting RNA-seq data from any eukaryotic species. This sui...

Anthropogenic habitat alteration can rapidly disturb native fish species by hybridization with introduced species. In Korea, the construction of water conduits has unilaterally introduced the allopatrically separated fish species Cobitis tetralineata from the Seomjin River to the Dongjin River where its sister species C. nalbanti inhabits. To asses...
Article
Chemical risk assessment for avian species typically depends on information from toxicity tests performed in adult birds. Early‐life stage (ELS) toxicity tests have been proposed as an alternative, but incorporation of these data into existing frameworks will require knowledge about the similarities/differences between ELS and adult responses. The...
Article
Early-life stage (ELS) avian toxicity tests have been proposed as a more ethical alternative to traditional standardized tests with adult birds. At the same time, 'omics approaches are gaining traction in the field of avian toxicology, but little has been done to characterize the metabolome and transcriptome at different life stages. The present st...
Article
Full-text available
The morphologically similar populations of the Korean freshwater spined loach recently described as a new species Cobitis nalbanti (Actinopterygii: Cypriniformes: Cobitidae) inhabit the rivers and streams on the Korean Peninsula that flow into the Yellow Sea and the Korea Strait. These shallow sea areas have experienced recurrent sea-level rises an...

The use of toxicogenomic endpoints and increased reliance on early-life stage (ELS) animal exposures are two strategies that have been proposed to improve toxicity testing for regulatory risk assessment. However, it is unknown whether transcriptomic measures in ELS organisms are predictive of those measured in their adult counterparts. The present...

Full-text available
Incorporation of toxicogenomics into ecological risk assessment requires a good understanding of the genes/pathways that are commonly affected by exposure to toxic chemicals. Studies comparing transcriptomic responses across environmental chemicals are available for fish but less research has been done for birds. The present study aims to reveal un...
Article
Full-text available
Genomic introgression through interspecific hybridization has been observed in some species of the freshwater fish family Cobitidae. Within this family, a Cobitis hankugensis–Iksookimia longicorpa diploid–triploid hybrid species complex on the Korean peninsula is unique in displaying hybridogenesis, a unisexual reproduction mode that allows hybrids...

Birds are sensitive indicators of ecosystem health, but avian toxicity data for many chemicals of environmental relevance are limited. The overall goal of our research project is to develop early-life stage (ELS) avian toxicity tests for rapidly screening chemicals of ecological and regulatory concern. Here, we use our recently developed standardiz...

Full-text available
We investigated whether tetraploidy in Iksookimia yongdokensis adds more species specific variation in its early life history characteristics. To this end, morphological and temporal characteristics were analysed using artificial fertilisation and laboratory culture, and the results were compared to seventeen other species of the family Cobitidae....
Article
The habitat, age and spawning characteristics of the Korean eastern spined loach, Iksookimia yongdokensis, were investigated to obtain baseline data for its ecological characteristics in the Chuksancheon (stream), Yeongdeok-gun, Gyeongsangbuk-do, Korea. The difference between the habitats of juveniles (0 +) and 1~4 year old loaches was that juvenil...

The sexually reproducing fish, Poeciliopsis monacha (Actinopterygii, Cyprinodontiformes, Poeciliidae), is the maternal ancestor of six hybrid biotypes that reproduce clonally. The gene content and order of its 16,818 bp mitochondrial genome is virtually identical with that of other sexually reproducing poeciliid fishes, providing no evidence for a...

Korea severely suffers from plastic-induced ocean pollution, but only few studies predicted the trajectory of marine plastic debris and provided their collection method. This study used Ocean Surface CURrent Simulator (OSCURS) of National Oceanic and Atmospheric Administration (NOAA) in order to predict the trajectories of marine plastic debris flo...
Article
The differentiation of sex is important for species preservation. However, Fairy Pitta is sexually monomorphic and sex of an individual is indistinguishable with its external characteristics. We determined the sex of Fairy Pitta through DNA analysis and investigated the causes and time of injury and mortality and the size based on sex. We collected...
Article
A Fairy Pitta is a bird known to breed only in mainland China, Taiwan, Japan and Korea and is listed as Vulnerable in the IUCN Red List. We carried out a DNA analysis to contribute to conserve the genetic diversity of Fairy Pitta. 32 samples were collected at Jeju Island, the Korean Peninsula and Taiwan from 2004 to 2013 and DNA was extracted from...
