Influence of Environmental Variables in Micropterus salmoides
Biological invasions in fresh waters cause biodiversity loss and impairment of ecosystem functioning. Many freshwater invasive species are fish, including the largemouth bass Micropterus salmoides, which is considered one of the 100 worst invasive species in the world. Fast individual growth rates, high dispersal ability, ecological tolerance, and trophic plasticity are among the characteristics contributing to its success. The negative impact of M. salmoides on littoral fish communities is believed to be mitigated by habitat structural complexity resulting from aquatic vegetation and coarse woody debris, while the main limits on its spread seem to be strong water flows and high turbidity, which impairs visual predation. Together with the human overexploitation of its potential fish antagonists, habitat alteration could result in M. salmoides having seriously detrimental effects on native biodiversity.

Climate Change and Salmonid Distribution
Salmonids are a cold-water species. Global warming will generally have a major impact on their success. Historically, climatic variability has affected the patterns of abundance in Atlantic salmon and Pacific salmon populations. Climate change will continue to affect not only smolting and migration but also instream habitats across all seasons.

One Health Observatories—The Example of Southeast Asia
One Health Observatories operationalize the One Health approach. The One Health Joint Plan of Action drafted by the Quadripartite (WHO, FAO, WOAH, and UNEP) insists on the need to strengthen scientific evidence-based knowledge and its translation into data for evidence, technical tools, protocols, guidelines, and information and surveillance systems for the effective implementation of One Health at all levels. One Health Observatories are crucial for this task. Drawing from the experience of the existing One Health Observatory in Thailand—a unique, on-the-ground initiative—we outline the key features of this model for potential replication in other regions or countries. Such observatories play a critical role in advancing ecosystem-based innovations and locally adapted solutions, which are necessary to improve the prevention of disease transmission at the interface between human, animal, and ecosystem health.
