For example, there is not necessarily a clear or consistent relationship between productivity and species richness. [25] Similarly, the relationship between resilience and diversity is complex, and ecosystem stability may depend upon one or a few species rather than overall diversity. [26] And some undesirable ecosystems are highly productive ...
Disease ecology is a sub-discipline of ecology concerned with the mechanisms, patterns, and effects of host-pathogen interactions, particularly those of infectious diseases. [1] For example, it examines how parasites spread through and influence wildlife populations and communities.

[1] Furthermore, wildlife disease is a disease when one of the hosts includes a wildlife species. In many cases, wildlife hosts can act as a reservoir of diseases that spillover into domestic ...
Although many of the dramatic effects of ecosystem change, and much of the research, are focused on developing countries, the ecosystem of the artificial environment in urban areas of the developed world is also a significant determinant of human health. Obesity, diabetes, asthma, and heart disease are all directly tied to environmental factors.

Though many infectious diseases are affected by changes in climate, vector-borne diseases, such as malaria, dengue fever and leishmaniasis, present the strongest causal relationship. One reason for that is that temperature and rainfall play a key role in the distribution, magnitude, and viral capacity of mosquitoes, who are primary vectors for ...
Forest pathology is the research of both biotic and abiotic maladies affecting the health of a forest ecosystem, primarily fungal pathogens and their insect vectors. [1] [2] It is a subfield of forestry and plant pathology.
