Microbiomes in Birds: A Review of Links to Health and Reproduction.

Microbiomes have emerged as a key component essential for maintaining the health of an organism. Additionally, the roles of microbiomes are multifaceted, some unique to specific body areas and organs while others, particularly the gut microbiome, having broader effects on the entire organism. Comparative literature is emerging that compares microbiomes across mammals and birds.

Global challenges in aging: insights from comparative biology and one health.

The well-being of wildlife populations, ecosystem health, and human health are interlinked, and preserving wildlife is crucial for sustaining healthy ecosystems. Wildlife numbers, and in particular avian populations, have steeply declined over the past century, associated with anthropogenic factors originating from industry, urbanization, changing land use, habitat loss, pollution, emerging diseases, and climate change. All these factors combine to exert increasing stress and impair health for both humans and wildlife, with diminished metabolic, immune, and reproductive function, deteriorating overall health, and reduced longevity.

Comparative biology and non-traditional approaches for basic aging research for facilitating translational studies.

As humans, we aspire to healthy aging and ideally reaching our maximal lifespan. That, however, requires optimizing resilience to stressors and minimizing exposure to factors that accelerate aging. Understanding the complexities of aging processes involves characterizing the causal bases of physical, physiological, and cognitive deficits that accumulate over time, eventually culminating in reduced functionality and decreased resistance to disease and environmental stressors.

The Importance of Fostering and Funding Scientific Research, and its Relevance to Environmental Toxicology and Chemistry.

What do environmental contaminants and climate change have in common with the virus SARS-CoV-2 and the disease COVID-19? We argue that one common element is the wealth of basic and applied scientific research that provides the knowledge and tools essential in developing effective programs for addressing threats to humans and social-ecological systems. Research on various chemicals, including dichlorodiphenyltrichloroethane and per- and polyfluoroalkyl substances, resulted in regulatory action to protect environmental and human health. Moreover, decades of research on coronaviruses, mRNA, and recently SARS-CoV-2 enabled the rapid development of vaccines to fight the COVID-19 pandemic.
