Dr. Amarachi Paschaline Onyena | Biodiversity And Conservation | Best Researcher Award

Lecturer | Nigeria Maritime University | Nigeria

Dr. Amarachi Paschaline Onyena’s research spans marine biology and aquatic environmental science, with a core focus on water sediment quality assessment, benthic macroinvertebrate ecology, ecotoxicology, molecular characterization, and environmental risk evaluation. Her work examines how pollutants such as heavy metals, hydrocarbons, and microplastics influence aquatic ecosystems, using integrated approaches that combine biomonitoring tools, molecular techniques, and analytical assessments to understand contamination pathways, ecological stress responses, and indicators of ecosystem degradation. She contributes extensive research on mangrove ecosystem dynamics, sediment biogeochemistry, and the role of macrobenthic communities as sensitive bioindicators of environmental change. Through field investigations, experimental analyses, and systematic reviews across diverse Nigerian aquatic environments, she provides evidence-based insights for pollution mitigation, microplastic monitoring, and sustainable aquatic resource governance. Her involvement in environmental risk assessments, consultancy-based evaluations, and collaborative marine studies supports policy development for coastal sustainability and blue-economy advancement. Contributions to global platforms, including work for the United Nations World Ocean Assessment, reflect her commitment to translating scientific findings into practical frameworks for ocean governance. With 590 citations, 29 indexed documents, and an h-index of 12, her growing research impact highlights her role in advancing marine pollution science, improving environmental monitoring frameworks, and promoting evidence-based strategies for resilient coastal and marine ecosystems.

Education

Marília Marques da Silva holds a Bachelor’s degree in Biology from the Universidade Federal da Bahia (UFBA). She earned her Master’s degree in Ecology and Biodiversity Conservation from the Universidade Estadual de Santa Cruz (UESC), where she is currently pursuing her PhD in the same field. Her academic journey includes enriching international experiences through research internships at the Universidad de Málaga (Spain) during her undergraduate studies and at CIBIO – Universidade do Porto (Portugal) during her Master’s. Additionally, she has obtained an MBA in Project Management, demonstrating a strong interdisciplinary background that bridges science and strategic planning.

Experience

Marília has developed extensive field and analytical experience through her work on in situ and ex situ conservation projects, particularly focused on Neotropical mammals. Her Master’s research analyzed how environmental and anthropogenic variables influence mesocarnivore occupancy in the Atlantic Forest, while her PhD expands on this by examining coexistence mechanisms in forested landscapes. She has also participated in consultancy projects, including wildlife monitoring and rescue operations, in collaboration with environmental firms. These diverse roles have strengthened her expertise in fieldwork coordination, species monitoring, and ecological data analysis.

Award and Honor

While formal awards are not listed yet, Marília’s contributions have been recognized through research publications, including a peer-reviewed article in Perspectives in Ecology and Conservation (Elsevier/Scopus). She has published a book chapter based on her ecological fieldwork and is actively engaged in international collaborations with institutions in Europe and Brazil, including IPE, CENAP, and Pro-Carnívoros. Her growing academic visibility and research outputs highlight her as a promising early-career scientist in the field of tropical mammal conservation.

Research Focus

Marília’s research centers on the ecology and conservation of Neotropical meso- and large mammals, particularly in human-modified landscapes. Her work investigates the impacts of anthropogenic disturbances on mammalian distribution and behavior, using occupancy models, camera trap data, and ecological theory to inform conservation efforts. By exploring species interactions, resource use, and habitat partitioning, she aims to propose effective strategies that reconcile biodiversity preservation with sustainable development in threatened ecosystems like the Atlantic Forest.

Research Skill

Marília combines technical and soft skills that enhance her contribution to ecological research and conservation. Her competencies include field survey design, camera trapping, biodiversity monitoring, occupancy modeling, and spatial ecology. She is skilled in data analysis using statistical software and in managing collaborative research projects. Her academic foundation is supported by project management skills gained through her MBA. She also communicates effectively in multilingual environments, and her ability to work across international teams further enriches her professional profile.
