Dr. Estelle Crochelet’s research focuses on marine ecology, biodiversity conservation, and sustainable management of tropical and island ecosystems in the Western Indian Ocean. As a Marine Ecologist at the Biodiversity Research Agency of Réunion Island (ARBRE), she integrates field ecology, molecular analysis, and spatial modeling to study coral reef systems, mesophotic ecosystems, and species connectivity. Her pioneering application of environmental DNA (eDNA) techniques has transformed biodiversity monitoring by enabling the detection of rare and cryptic species such as sharks and rays, advancing ecosystem-based management and conservation planning. Through leadership roles in major initiatives including the IRRAE, MAEO, and CONCILIER programs, Dr. Crochelet has contributed to integrated coral reef management, linking ecological research with territorial planning and policy implementation. Her interdisciplinary work, combining marine biology, remote sensing, and ecological modeling, has generated valuable insights into habitat connectivity, reef resilience, and marine spatial planning. Collaborating with organizations such as IUCN, IRD, and the French Biodiversity Office, she has played a vital role in shaping regional conservation strategies and advancing scientific understanding of marine ecosystems. Widely published in prestigious journals such as Nature, Science, Environmental DNA, and Deep Sea Research, Dr. Crochelet’s work has global relevance, addressing the challenges of biodiversity loss and climate impacts on marine environments. Alongside her scientific achievements, she mentors emerging researchers, leads citizen science initiatives, and promotes public awareness of ocean conservation. A certified professional diver, rebreather user, and drone pilot, she combines technical field expertise with innovative research approaches, making significant contributions to sustainable marine governance and biodiversity preservation in the Southwestern Indian Ocean.

Education

Dr. Yang pursued his academic journey through a series of progressive and specialized degrees in geographical and environmental sciences. He earned his Ph.D. in Geography from Lanzhou University, where he laid the foundation for his research in ecosystem services and socio-ecological systems. Prior to this, he completed his Master’s degree in Physical Geography at Ningxia University, focusing on land use, soil properties, and regional environmental changes. His undergraduate studies in Geographical Science at Weinan Normal University provided him with a strong grounding in environmental analysis and spatial modeling.

Experience

Dr. Yang’s academic career advanced swiftly through rigorous postdoctoral research and faculty appointments. He served as a Cuiying Postdoctoral Fellow at Lanzhou University, engaging in high-impact studies on ecosystem services in fragile mountainous regions. He was appointed as Associate Professor in the same institution, where he continues to contribute to both teaching and research. Over the past five years, he has led or participated in numerous national and provincial projects, including a National Natural Science Foundation grant investigating spatiotemporal evolution of water supply services and socio-ecological value mechanisms in the Qilian Mountains, and a prestigious China Postdoctoral Fellowship on the coupling effects of climate and land use change.

Research Focus

Dr. Yang’s research focuses on the assessment, valuation, and modeling of ecosystem services in ecologically sensitive areas, particularly in the Qilian Mountains and the broader Yellow River Basin. His work incorporates spatial analysis, socio-ecological modeling, and sustainability science to explore themes such as spillover effects of ecosystem services, cost-benefit sharing, horizontal ecological compensation, and human well-being. He has also investigated land use impacts, biodiversity-climate interactions, and resource efficiency in agricultural and pastoral systems. Through these research areas, he aims to offer scientific support for environmental planning, ecological restoration, and regional sustainable development strategies in China’s western regions.

Title: Assessing Pollinator Abundance and Services in the Qilian Mountains: A Spatial and Temporal Analysis from 1990 to 2020 for Enhanced Agricultural Sustainability and Crop Yield Optimization
Authors: Yang, H.; Gou, X.; Niu, Y.; Shi, W.; Wang, X.; Wei, Y.; Maraseni, T.
Journal: SSRN
Summary: This study investigates changes in pollinator abundance and ecosystem services in the Qilian Mountains from 1990 to 2020. It highlights spatial and temporal patterns and links pollinator dynamics to agricultural sustainability and crop yield improvements.

Title: Increasing Deep Soil Water Uptake During Drought Does Not Indicate Higher Drought Resistance
Authors: Yin, D.; Gou, X.; Liu, J.; Zhang, D.; Wang, K.; Yang, H.
Journal: Journal of Hydrology 
Summary: This research challenges the assumption that deep soil water uptake enhances drought resistance in plants. Using tree-ring and isotopic data, the study reveals that although trees may access deep water during drought, this does not guarantee improved growth or resilience, emphasizing the need to rethink forest management strategies under climate change.

Title: Response of Tree Growth to Drought Variability in Arid Areas: Local Hydroclimate and Large-Scale Precipitation
