전 세계적으로 생물다양성을 보호하기 위한 방법으로 보호지역을 지정하고 있지만, 보호지역에 대한 관리 부족으로 효과성을 평가하기 어렵다. 보호지역 효과성 평가를 위해 다양한 지표들을 이용하여 평가하고 있다. 그 중 토지피복 변화 분석은 경제적이고 장기적인 변화 파악이 가능하며, 공간적 제한이 상대적으로 적어 다양한 대상지에서 활용할 수 있다는 장점이 있다. 본 연구에서는 토지피복 변화를 이용하여 야생생물 보호구역의 효과성 평가를 목적으로 한다. 보호지역 내부와 외부, 타 보호지역과의 중복지정 여부, 지정 시기에 따라 과거 자연지역이 농업지역 또는 시가화건조지 역으로 변화한 비율을 분석하였다. 연구 결과로 첫째, 보호지역 내부에서는 보호 효과가 있지만, 외부에서는 개발압력이 있음을 알 수 있다. 둘째, 타 보호지역과 중복된 보호지역일수록 효과가 있음을 알 수 있다. 셋째, 지정 시기가 오래된 보호지역일수록 시간이 지남에 따라 토지피복 변화가 줄어들어 지속적인 효과가 있음을 알 수 있다. 본 연구는 경제적이 고 장기적 변화 파악이 가능한 토지피복을 이용하여 보호지역의 효과성을 정량적으로 평가했다는 점에 의의가 있다. 토지피복은 끊임없이 변화할 것이며, 드론과 같은 첨단장비를 이용하여 실시간 모니터링을 한다면 보호지역의 효과와 압력을 더욱 신속하고 정밀하게 평가할 수 있을 것이다.

Road infrastructure development and biodiversity conservation are essential for sustainable development. However, many developing countries struggle to balance them. This study examines the impact of road construction in 24 African countries and evaluates strategies for achieving sustainability. Using a case study approach, road construction variables from individual country reports (2024) were quantitatively analyzed alongside Red List Index (RLI) scores from the Yale University's 2024 Environmental Performance Index Report. Descriptive statistics and regression analyses were applied to assess the relationship between road development and biodiversity conservation to provide insights into effective mitigation strategies. Results indicate that in 2024, the average RLI score for the 24 African countries was 64.74, with a 10-year mean decline of -2.85. On average, 17,162.21 ha of biodiversity habitats were cleared for road construction, emphasizing the vulnerability of biodiversity. Burkina Faso (95.4), Mali (92.9), and Botswana (92.2) exhibited strong biodiversity health, whereas Kenya (24.9), South Africa (24.4), Uganda (15.7), and Tanzania (0) faced critical challenges. Wildlife crossing was the most significant predictor in lower-income economies (R² = 0.49, p < 0.0001), traffic volume in lower-middle income economies (R² = 0.35, p = 0.0007), and road width in upper-middle income economies (R² = 0.83, p = 0.0054). Habitat clearance exhibited a weak correlation. These findings highlight the crucial role of road construction variables—particularly wildlife crossings, road width, and traffic volume—in biodiversity conservation across income groups. Targeted road planning is required to mitigate biodiversity loss. These findings contribute to the emerging literature on the impact of infrastructure on conservation, policy guidance, and mitigation efforts in developing countries.

자연환경은 인간의 삶과 밀접하게 연결되어 있으며, 다양한 형태로 혜택을 제공한다. 인간은 생태계로부터 직·간접적 인 혜택을 받는데, 이를 정량적으로 평가한 개념을 생태계서비스라고 한다. 본 연구는 산림유전자원보호구역, 습지보호 지역과 독특한 미기후현상으로 인해 북방계 및 고산식물이 잔존하여 보호 가치가 높은 풍혈지까지 3가지 유형을 대상으 로 생태계서비스를 평가하였다. 서식지질(Habitat Quality) 및 탄소저장량(Carbon)을 InVEST 모델을 활용하여 정량적 으로 분석하였으며, 연구 대상지는 산림유전자원보호구역(가지산, 불모산, 가덕도), 습지보호지역(사자평, 신불산, 화엄 늪), 풍혈지(밀양 얼음골, 의성 빙계계곡, 함화산) 총 9개 지역으로 선정하였다. 서식지질 분석 결과, 전체 평균은 0.83으로 나타났으며, 보호지역 내부의 서식지질이 외부보다 전반적으로 높았지만, 사자평 고산습지의 경우 억새군락지 로 인해 인공초지가 포함되어 내부가 서식지질이 더 낮게 나타났다. 또한, 서식지질이 높을수록 대상지 면적이 증가하 며, 위협 수준이 감소하는 경향이 나타났다. 이는 인위적 간섭과 개발이 위협요인과 직결되며, 서식지질 저하와 대상지 의 면적이 밀접한 연관이 있음을 확인하였다. 탄소저장량 분석에서는 김해 불모산이 가장 높은 값을 보였으며, 의성 빙계계곡이 가장 낮은 값을 기록하였다. 대상지 면적이 클수록 탄소저장량이 높은 경향을 보였으며, 탄소저장량 구성 비율에서는 지상부 바이오매스가 가장 큰 비중을 차지하였다. 탄소저장량 변화를 살펴보았을 때, 사자평 고산습지가 가장 크게 감소하였는데, 인간의 간섭과 개발이 토지유형 변화에 영향을 미친 것으로 판단된다. 본 연구는 산림생물다양 성 특정지역의 중요성을 정량적으로 평가함으로써 보호전략 수립에 필요한 과학적 근거를 제공하는 데 기여할 수 있다. 특히, 보호지역 후보지인 풍혈지에 대해 생태계서비스를 평가하여 향후 OECM 지정 가능성을 검토하는 기초 자료로 활용될 수 있으며, 보호지역의 다양성과 특수성을 고려한 맞춤형 보전 정책 수립에도 유용한 정보를 제공할 것으로 기대된다.

A study of intertidal habitats on Jejudo Island, Korea led to the identification of two new species, Desmoscolex (Desmoscolex) jejuensis sp. nov. and Desmoscolex (Desmoscolex) longispiculatus sp. nov., belonging to the subgenus Desmoscolex. Desmoscolex (D.) jejuensis sp. nov. is distinguished by the presence of 18 main rings, with males missing the 8th, 10th, and 14th subventral setae with the 2nd and 15th setae shifted laterally. In females, the 6th, 8th, 10th, and 14th subventral setae are absent. Conversely, D. (D.) longispiculatus sp. nov. exhibits 17 main rings with a typical somatic setae arrangement along with notably elongated spicules and the 14th and 15th subventral setae shifted laterally or slightly subdorsally. Both species are characterized by relatively long and slender cephalic setae. Detailed illustrations and high-magnification micrographs were produced using differential interference contrast (DIC) microscopy and scanning electron microscopy (SEM) to facilitate morphological comparisons between these new species and related taxa. Furthermore, a comparative trait table and a pictorial key are provided to clearly differentiate these new species from morphologically similar taxa. These findings contribute to the understanding of nematode biodiversity and contribute to the broader knowledge of Desmoscolex diversity in Korean coastal ecosystems.

Biodiversity encompasses species diversity, which includes species richness and species evenness. High species diversity is known to contribute to community stability and the potential for maintaining healthy ecosystem functioning. However, the most commonly used species diversity indices have some limitations, as they require species-specific abundance data for each community. In contrast, phylogenetic diversity measures the evolutionary distances between species within a community, reflecting ecological and/or evolutionary divergences and niche differences, without requiring abundance data. This study assessed biodiversity by calculating phylogenetic diversity indices for freshwater fishes (19 species) and aquatic insects (49 species) at three sites within Seoraksan and Odaesan National Parks. The aquatic insects studied belong to the EPT group (Ephemeroptera, Plecoptera, and Trichoptera), which are widely used as bioindicators of aquatic ecosystems. Two mitochondrial DNA genes were used as molecular markers: COI and cyt b for fish, and COI and 16S rRNA for the EPT - group. Overall, Odaesan National Park exhibited higher phylogenetic diversity in both fishes and aquatic insects compared to Seoraksan National Park, although this difference was not statistically significant. The highest phylogenetic and species diversity were observed for fish at the OD2 site (Woljeong District) and for the EPT group at the OD1 (Gyebangsan) and SA2 (Jangsudae) sites. Correlation analysis revealed that phylogenetic diversity indices were more positively associated with species richness than species diversity indices. This study serves as a pilot project for establishing standardized methods for assessing biodiversity in national park habitats using phylogenetic diversity. It also aims to inform various policies, such as the development of biodiversity assessment systems and the prioritization of protected areas within national parks.

This study reassessed two KBA sites in the Republic of Korea following the KBA guidelines. Both sites met the sub-criteria A1a, A1b, and D1a, confirming their status as KBA. These assessments provide a scientific foundation for discussions on designating new protected areas or expanding existing ones. Through this study, we confirmed that continuous biodiversity conservation is essential for Geum-gang river and estuary and Yubu-do to maintain their KBA status. This KBA reassessment provides an important scientific foundation for discussions on the designation of new protected areas or the expansion of existing ones. Furthermore, this study was based on a previously evaluated taxonomic group, birds, highlighting the need for future assessments to include other biological taxa and evaluation criteria, such as Criteria B or E, for a more comprehensive analysis.

This study aimed to collect foundational data essential for devising a natural environment conservation plan and implementing relevant policies. It underscores the significance of understanding the current state of the natural environment. Our research concentrated on surveying the biodiversity and distribution of key natural habitats within Busan Metropolitan City, with the goal of gathering crucial data to guide the development of conservation and management strategies. The focus of our investigation was on the insect populations in Ilgwang, covering two primary habitats: mountains and wetlands. The survey, conducted from July to September 2023, utilized various collection methods, including pitfall traps, fly traps, sweeping nets, and aspirators. Our findings documented the presence of 109 species across 88 genera, 50 families, and 9 orders. Specifically, the study identified two species from the order Odonata, two from Blattodea, one from Mantodea, six from Orthoptera, eleven from Hemiptera, twenty-nine from Coleoptera, twelve from Diptera, ten from Lepidoptera, and thirty-five from Hymenoptera. Through community analysis, biodiversity indices were calculated, revealing a Shannon-Wiener index (H') of 4.07 for mountain habitats and 3.92 for wetlands. The Margalef richness index (R) displayed values of 13.92 for mountains and 14.78 for wetlands, while the Pielou evenness index indicated values of 0.96 and 0.91, respectively. Among the identified species, one was classified as endangered, and thirteen were designated as of Least Concern, according to legal protection statuses.

Spiders play an important role in regulating insect pests in the agricultural ecosystem. The community structure and biodiversity of rice field spiders were surveyed in 5 areas (Anseong, Nonsan, Imsil, Namwon, and Gurye) from 20 May to 30 September, 2021. A total of 5,525 spiders collected were identified as 64 species of 17 families. Species richness and abundance were high in Lycosidae, Tetragnathidae and Linyphiidae. The similarity of rice field spider communities among regions was about 72% and was divided into three groups: the middle inland area, the southern mountainous area, and the southern inland area. Species diversity averaged as 2.55±0.06. On the seasonaliy of The boidiversity tended to increase toward the latter half of cultivation.

The study of blowfly (Diptera, Calliphoridae) biodiversity and distribution is crucial for forensic investigations involving cadavers. Abiotic and biotic factors, such as seasonality and habitat type, have significant impacts on blowfly populations. However, few forensic entomology studies have been conducted in South Korea, particularly the Gyeongsangnam-do region. To address this, in this study, an extensive year-long survey was conducted to analyze the compositions, habitat preferences, distribution, and seasonal abundance of forensically relevant blowflies in urban and forested habitats in Gyeongsangnam-do, utilizing mouse carcass-baited traps set for 48 h each month. A total of 3,478 adult blowflies were recorded, encompassing six genera and 14 species, with a noted absence of specimens during the winter months. The predominant species was Lucilia porphyrina, accounting for 37.1% of the total sample, followed by Chrysomya pinguis (27.5%), Lucilia sericata (7.6%), and Lucilia illustris (7.1%). The species composition was consistent across all surveyed regions; however, seasonal variation in species diversity was evident, with a peak in spring and decline in summer. Notably, certain species exhibited clear preferences for either urban (Calliphora calliphoroides and L. sericata) or forested habitats (L. porphyrina and Ch. pinguis). This pioneering study elucidates the diverse blowfly communities in Gyeongsangnam-do, highlighting significant seasonal and habitat-dependent variations.

Ecosystems provide various ecosystem services based on biodiversity. However, biodiversity is facing crises due to anthropogenic factors such as pollution, land use change, and climate change. Threats to biodiversity can significantly impact the provision and stability of ecosystem services, extending beyond simple species decline. To address threats to biodiversity, it is crucial to evaluate how anthropogenic factors affect not only biodiversity but also ecosystem services. This study aims to investigate the energy flux in a post-mining area based on the biodiversity of soil ecosystems and assess its suitability as an evaluation metric. It was observed that as the concentration of the primary pollutant, arsenic, increased, both the biomass of soil organisms and energy flux decreased. Furthermore, soil ecosystem multifunctionality may be negatively affected by pollution. These findings contribute to understanding the impact of pollution on soil ecosystem biodiversity and energy flux in post-mining areas and provide important information for more effective conservation and management of ecosystem services.

수서곤충은 일반적으로 하루살이목, 날도래목, 강도래목, 잠자리목, 노린재목, 딱정벌레목, 뱀잠자리목, 파리 목의 8개의 목(Order)에 속하며, 물을 기반으로 서식하는 곤충들을 의미한다. 국내 수서곤충의 연구는 도입기 (40-50년대), 형성기(60년대), 발전기(70-80년대), 도약기(90-2010년대)를 거쳐 왔다. 물을 기반으로 수질을 평가 하기 위해 수서곤충은 생태학적 연구가 먼저 시작되었으며, 이후 분류학적 연구가 시행되고 현재는 유전학적 및 응용학적 연구로 다양성을 증명하고 있다. 하지만, 물을 기반으로 하는 수서곤충의 서식처는 도시화로 인한 다양한 개발과 교란으로 감소하고 사라지고 있다. 서식처뿐만 아니라 수서곤충을 연구하는 학자들과 학생들도 정체기와 쇠퇴기를 거치고 있다. 국내 수서곤충의 다양성 종 목록은 1999년 처음으로 학술논단에서 491종이 정리되었으며, 이후 약 10년 만에 개정목록이 2011년에 988종으로 수정되었다. 이후 지속적인 국가생물다양성 확보 및 보전 전략에 따라 미발굴된 수서 파리류들이 대거 기록되면서 2018년에는 처음 기록보다 3배 이상 증가하 여 1,567종이 보고되었다. 이처럼 표면적으로는 수서곤충의 연구가 활성화되어 다양성은 늘어가고 있는 것처럼 보이지만 다양한 문제점들이 나타나고 있다. 수서곤충은 성충보다는 유충을 주로 연구하는 학문으로 많은 연구 자가 어려움을 겪고 있다. 단기간의 다양성 증진보다는 심도 있는 다양한 주제로 접근하는 방법이 필요할 것으로 보이며, 수서곤충의 다양성과 함께 서식처 회복 및 복원 방안도 함께 마련되어야 할 것으로 판단된다. 본 발표에서 는 국내 수서곤충의 다양한 연구주제와 피해 상황 및 활용방안을 소개하여 미래의 수서곤충의 방향성과 연구 방향을 심도 있게 논의하고자 한다.

This study was conducted to select indicators for assessing national biodiversity. For this purpose, 140 biodiversity-related indicators were identified as a result of inventorying biodiversity-related indicators used in Korea and abroad, and when these indicators were applied to the pressure, status, and response indicator system, it was found that status indicators accounted for the largest number of indicators, with 29 pressure, 59 status, and 44 response. We also categorized the status indicators into genes, species, habitat, function, and quality, and found that species and habitat indicators accounted for the majority. Pressure indicators were categorized into direct exploitation, pollution, alien species, climate change, and habitat change. As a result, it was found that direct exploitation and pollution accounted for most of the pressure indicators. In addition, this study used internationally used indicator selection criteria to establish criteria for selecting domestic biodiversity assessment indicators. Using this list of indicators and indicator selection criteria, we evaluated the prioritization of domestically applicable biodiversity indicators through relevant expert consultations. 1) Vegetation class, 2) Land cover indicators, and 3) Change of protected area ranked highly. In fact, these indicators have been used in many studies due to the availability of assessable data. However, most of the highly scored indicators are based on ecosystem area, and further consideration of ecosystem functions and components (species) is needed.

eDNA (environmental DNA)란 특정 환경에 서식하는 생물로부터 유래한 DNA를 의미한다. 환경 시료로부터 추출한 eDNA를 활용하면 해당 환경에 서식하는 생물들의 효율적이고 정확한 모 니터링을 수행할 수 있다. 해수 시료로부터 얻은 eDNA를 기반으로 해양생물 다양성 연구를 수행할 수 있다. 해수 시료를 채집하고 이로부터 eDNA를 추출한 뒤, metagenome 분석을 통 해 서식하는 해양생물의 종 동정과 다양성 분석이 가능하다. 본 리뷰에서는 이처럼 해수의 eDNA를 활용하여 해양 지역의 생물 다양성 연구를 수행하는 전체적인 과정을 제시하고 있다. 아직 국내에는 해양생물 다양성 연구를 위해 eDNA를 적용하는 방법이 보편화 되어있지 않으 며, 본 리뷰를 기반으로 이와 같은 eDNA 연구 방법을 정립하는데 도움을 줄 수 있을 것이다.

The legal status of Biodiversity Beyond National Jurisdiction (BBNJ) has been regulated through the High Seas Treaty as a common heritage of humankind. However, there still exist problems related to overlapping areas above the Extended Continental Shelf (ECS). In such areas, a significant continental shelf would fall within national jurisdiction, whereas the water column would be under the regime of the high seas, and BBNJ would be the common heritage of humankind. We argue that, in order to address the overlapping of areas within the superjacent waters in the ECS, a given sui generis status is required, so that the coastal state has a sovereign right to conserve the BBNJ in these areas. This study concludes that the sui generis arrangement should be implemented in the context of an overlapping ECS and its water column. The efforts of the Indonesian government to extend the continental shelf beyond 200 nautical miles constitute an important step in preserving natural resources for future generations.
