Background: This article examines the intersection of two global trends, super-diversity and globalized aging, in the context of urban communities. Super-diversity refers to the impact of changing immigration patterns on social, health, and economic systems. Interdisciplinary by definition, gerontological social work practice bridges macro, mezzo, and micro modalities, as well as professional and disciplinary false divides.Objective: The authors aim to highlight how urban gerontology practice can benefit from reaching across borders and boundaries. Goals include identifying best practices of care that can serve as models in a range of environments.Methods: The authors used a qualitative case study approach. Data collection consisted of individual interviews and focus groups.Findings: Findings suggest the ongoing relevance of ecological theory in the context of identifying best practices in social work gerontology.Discussion: Through the lens of super-diversity and globalized aging, the authors examine processes and impacts at the intersection of migration, advanced age, and care systems in the urban context. Findings indicate the need to further de-colonize aging care.

This thought-provoking book explores the influences of market competition and diverse behaviours of economic agents on economic performance, particularly dynamic economic performance. -- Clem Tisdell illustrates – within evolutionary, dynamic and static contexts – how diversity can improve or impede economic performance. He addresses the fact the role of diversity in improving economic performance has been neglected by economic theorists by making economic diversity a focal point of economic analysis. In particular, special attention is given to the value of economic diversity and economic imperfections in improving the performance of economic processes in particular identified situations. Limitations of using market-like mechanisms for managing public bodies and business firms are discussed and the value of business cooperation (economic mutualism) as a means for improving economic performance is examined. It is also observed that as economies develop, different forms of economic competition and business cooperation evolve. -- Challenging yet accessible, this book will prove a stimulating read for academics and students in the fields of economics, industrial organization and business and management.

"Bringing together the viewpoints of leading ecologists concerned with the processes that generate patterns of diversity, and evolutionary biologists who focus on mechanisms of speciation, this book opens up discussion in order to broaden understanding of how speciation affects patterns of biological diversity, especially the uneven distribution of diversity across time, space and taxa studied by macroecologists. Written for graduate students and academic researchers, the book promotes a more complete understanding of the interaction between mechanisms and rates of speciation and these patterns in biological diversity."--Jacket

This article adapts the model of ecological consultation to promote diversity and inclusion in higher education. Practical applications of ecological consultation aligned with systems theory will be shared to assist an organization in systems change. The ecological branch of consultation provides guidelines that can be utilized by change agents to lead the charge for a more inclusive environment. Examples steeped in both theory and practical applications will provide guidance for others thinking of leading this process at their institutions.

The most frequently overlooked aspect of conservation of natural resources and economic development is human cultural diversity. However, conservation and development of natural resources are basically human-oriented endeavors and all conservation and developmental efforts ought to start with a clear understanding of the varied needs of the people. In addition, cultural diversity is a natural resource that ought to be protected along with all the more commonly recognized resources of the ecosystems of which humans form an integral part. Cultural diversity in a large measure is an ecological phenomenon because such diversity includes variations in the ways different peoples perceive and utilize the environments in which they live. Thus, cultural diversity, in large measure, equates with ecological diversity. It has been well established that a high degree of ecological diversity (including taxonomic, niche, biogeochemical and other measures of diversity) is a necessary attribute of humid tropical ecosystems if such ecosystems are to remain viable over long periods of time. The current land-use trends in Central America and Panama are leading toward ever larger areas being devoted to monocultural use with sharply reduced ecological diversity that poses great dangers for the near and long terms. In addition, the resultant removal of people from rural areas results in growing social, economic and political problems, that are not being successfully met by developing nations. Not only is there a growing wastage of human resources, a weakening of the social structures, and an increasing and dangerous dependence upon monocultures oriented toward export markets, but the ecological diversity of the previous existing land-use systems are being lost. This kind of diversity is probably no less valuable to the ecological health of a nation's agriculture, forestry , and general resource utilization than is the genetic diversity of "primitive" crop plant varieties which biologists now recognize and increasingly seek to preserve ...

AbstractFreshwater ecosystems are intricately linked to the diversity and abundance of zooplankton assemblages, which serve as vital indicators of environmental conditions. The aim of the present study was to investigate the habitat ecology in relation to zooplankton abundance of the Ravi River. Sampling was conducted at selected sampling sites along the Ravi River basin, encompassing various habitat types and environmental gradients. A total of 13 species of zooplankton were observed during the study in which Copepoda was most dominant followed by Cladocera. Cyclops sp. (152 ind/L) and Bosmina sp. (145 ind/L) were the dominant genera throughout the study. Asplanchana sp. (44 ind/L) was observed as a rare species during the study. Some habitat ecological parameters like water temperature, dissolved oxygen, and total dissolved solids show a declining trend in Zone 3. Turbidity was highest in Zone 3 and lowest in Zone 1, and almost all zooplankton genera showed a declining trend in Zone 3. Dissolved oxygen shows a significant positive correlation and directly influences the distribution of zooplankton assemblage structure. This study concludes that certain anthropogenic activities like municipal dumping, sand mining, and altered water flow have negatively impacted water quality and zooplankton diversity in the Ravi River. So, these types of activities should be monitored regularly and controlled immediately.

This study investigates the influence of habitat structure on the species diversity of anurans of Rivers State, Nigeria. This research was conducted between 2015 and 2019. The survey covered seven Local Government Areas (LGAs) and three ecological zones (lowland forest, freshwater swamp and short mangrove). The habitats included farmlands, fallow areas, swamps, streams and inundated areas, bush paths, human settlements and forested areas. Visual encounter and acoustic survey methods were used and species identification was aided by appropriate taxonomical keys. Diversity indices were computed using Past-exe statistical software. Nineteen amphibian species were encountered including members of the Arthroleptidae, Bufonidae, Dicroglossidae, Ranidae, Hyperoliidae, Ptychadenidae and Pipidae. Freshwater swamps and short mangrove ecological zones (characterized by human settlements and farmlands) had the lowest diversity of two and five amphibian species, respectively. The highest diversity comprised of eighteen amphibian species was recorded in forested habitats of the lowland forest/freshwater swamp ecological zone. 569 individuals were encountered at lowland forest/freshwater swamp ecological zone; 215 at lowland forest; 60 at short mangrove; and 28 at freshwater swamp ecological zone. Shannon diversity was highest in the lowland/freshwater swamp ecological zone (H=2.12) and lowest in the freshwater swamp zone (H=0.52). The results show that forested habitats comprised of the combination of lowland forest and freshwater swamp ecosystems host a greater diversity of amphibian species. We therefore recommend that lowland and freshwater swamp ecosystems in the State should be protected to support greater diversity of amphibians.
