The fact that the names of biotic and abiotic entities in ecology are also the subject of onomastic studies demonstrates an overlap between two scholarly fields. This study addresses the intersections between ecology and onomastics. It shows that the main branches of onomastics and the subbranches of geoonomastics are quite closely related to the subbranches of ecology. An ecologically centered approach is presented instead of the anthropocentric approach of traditional onomastics studies. In this context, ecological onomastics is proposed as a conceptual framework for onomastics in order to evaluate the names given to other living subjects, in parallel with the names given to individuals, groups, societies, or human communities. As subjects of ecological onomastics, in addition to some topics of general onomastics, names used for ecological units such as ecosystems, habitats, niches, biotopes, and biomes, such as forests, pastures, meadows, highlands, rivers, and lakes, are considered as subject headings. It is argued that ecological onomastics differs from general onomastics in terms of subject matter, approach, and evaluation. This differentiation stems from the fact that ecological onomastics is essentially ecologically centered. Thus, ecological onomastics focuses on tracing the past, present, and changing state of naming culture in addressing ecological problems at various scales, such as contemporary environmental issues, ecological imbalance, and climate change.
