At the start of the 21st century modern zoos and aquariums are expected to contribute to the survival of the species they display, to educate the public, and to maintain the physical and psychological well‐being of the animals in their care. For the future, however, zoos and aquariums will have to be extraordinary in both quality and accomplishments. In this article the characteristics of a world‐class zoo or aquarium are described, ranging from organizational structure and philosophy, and staff recruitment and training, to animal care and husbandry, research, conservation, education and exhibit design. The importance of inter‐institutional co‐operation, technology, government affairs, marketing and development, and public relations are also discussed. In the future managers will have to take a more holistic approach to all these characteristics in order to achieve their core mission without losing sight of the primary objectives of the zoo or aquarium.
Regional collection planning and implementation are essential if professional zoological parks and aquariums are to achieve their collective conservation and animal management goals. Several regional associations currently have taxon advisory groups (TAGs) in place whose primary role is to develop taxon-specific collection plans. During their planning process, TAGs review all known taxa of interest and evaluate them based on relevant criteria. TAGs also evaluate the total amount of captive space available to determine the number of priority taxa that can be maintained. In addition, some TAGs heighten their impact on conservation by producing an action plan of select conservation and research projects to be supported by participating institutions. Although current guidelines for regional collection plan (RCP) development are extremely useful for some TAGs, such as those for most mammalian taxa, they do not address the needs of other more speciose TAGs, such as those for fish, invertebrates, and amphibians. These TAGs, characterized by their numerous taxa and more flexible space requirements, still need to develop plans for the species they manage. We recommend that highly speciose TAGs make development of an action plan their highest priority and use it to direct the RCP process. This will limit the number of taxa they need to consider, while ensuring that their RCPs are directly relevant to conservation. Once their action plans have been developed, speciose TAGs can then determine which species are most important to zoological collections and at what level they should be managed. This strategy represents a departure from the current processes used to develop RCPs for many mammalian and avian species and, as such, has not yet been addressed. An action plan-driven approach will result in more practical and relevant planning for speciose TAGs.
ImportanceAt least 500 000 people in the US experience homelessness nightly. More than 30% of people experiencing homelessness also have a substance use disorder. Involuntary displacement is a common practice in responding to unsheltered people experiencing homelessness. Understanding the health implications of displacement (eg, “sweeps,” “clearings,” “cleanups”) is important, especially as they relate to key substance use disorder outcomes.ObjectiveTo estimate the long-term health effects of involuntary displacement of people experiencing homelessness who inject drugs in 23 US cities.Design, Setting, and ParticipantsA closed cohort microsimulation model that simulates the natural history of injection drug use and health outcomes among people experiencing homelessness who inject drugs in 23 US cities. The model was populated with city-level data from the Centers for Disease Control and Prevention’s National HIV Behavioral Surveillance system and published data to make representative cohorts of people experiencing homelessness who inject drugs in those cities.Main Outcomes and MeasuresProjected outcomes included overdose mortality, serious injection–related infections and mortality related to serious injection–related infections, hospitalizations, initiations of medications for opioid use disorder, and life-years lived over a 10-year period for 2 scenarios: “no displacement” and “continual involuntary displacement.” The population-attributable fraction of continual displacement to mortality was estimated among this population.ResultsModels estimated between 974 and 2175 additional overdose deaths per 10 000 people experiencing homelessness at 10 years in scenarios in which people experiencing homelessness who inject drugs were continually involuntarily displaced compared with no displacement. Between 611 and 1360 additional people experiencing homelessness who inject drugs per 10 000 people were estimated to be hospitalized with continual involuntary displacement, and there will be an estimated 3140 to 8812 fewer initiations of medications for opioid use disorder per 10 000 people. Continual involuntary displacement may contribute to between 15.6% and 24.4% of additional deaths among unsheltered people experiencing homelessness who inject drugs over a 10-year period.Conclusion and RelevanceInvoluntary displacement of people experiencing homelessness may substantially increase drug-related morbidity and mortality. These findings have implications for the practice of involuntary displacement, as well as policies such as access to housing and supportive services, that could mitigate these harms.
