Wetland Habitats

Many long-legged wading birds such as little blue herons (Egretta caerulea), great blue herons (Ardea herodius), and great egrets (Ardea albus) nest together in large aggregations called breeding colonies. Although different species vary in their habitat preferences, wading birds have several common requirements for nesting. Colony sites must provide protection from predators, nesting materials, and nearby foraging areas (Hafner 2000). In the past, wading birds nested in natural wetland habitats that are becoming increasingly scarce as wetland habitats are continually altered or degraded to accommodate human needs. The future success of wading bird populations may be determined by how well they cope with manipulated foraging and nesting habitats. In this document, we make recommendations on the creation of nesting islands for long-legged wading birds.  This document is CIR1473, one of a series of the Wildlife Ecology and Conservation Department, UF/IFAS Extension.

Wetland Habitats

The American alligator once occupied all wetland habitats in south Florida, from sinkholes and ponds in pinelands to freshwater sloughs to mangrove estuaries. Nearly all aquatic life in the Everglades is affected by alligators (Beard, 1938). As a top predator in their ecosystem, they undergo an extraordinary change in body size and consume different prey items as they grow. As ecosystem engineers, the trails and holes that alligators build provide refuge for wading birds and fish during the dry season, and their nests provide elevated areas for nests of other reptiles and germination of plants less tolerant of flooding. This document is Cir 1478, one of a series of the Wildlife Ecology and Conservation Department, University of Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences.

Florida's geological history has been principally affected by changing sea levels, which influenced the formation of bedrock, the resulting soils, and surface topography. These geological factors influence Florida's plant communities, which support animal communities. Geological history, therefore, has influenced Florida's  environment and ecology in the past, during the present, and will continue to have effects in the future. This document is Fact Sheet WEC 189, one of a series of the Department of Wildlife Ecology and Conservation, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

AbstractEffective treatment of frequent oil spills and endless discharged oily wastewater is crucial for the ecosystem and human health. In the past two decades, the collection of oil from water surface has been widely studied through the simple fabrication of superhydrophobic meshes with various coating materials, but little attention is paid to the design aspects of the meshes based oil-collecting device and practical oil collection. Here, 3D-printing devices with different configurations of (super)hydrophobic meshes, circular truncated cone (CTC), cylinder and inverted CTC, and the same inverted cone-shaped structure (below the meshes for temporary oil storage) are investigated. Results demonstrate that the CTC meshes based device especially for an oblate one not only shows higher stability and discharge of the collected oils than previous reports, but also allows floating oils to enter the (super)hydrophobic mesh faster. We anticipate that future success in developing high-performance (super)hydrophobic meshes and the further optimization of the CTC mesh-based device parameters will make our proposed device more practical for the treatment of real-life oil spills.

Ferroelectric Perovskite

Taking a historical perspective, we provide a brief overview of the first-principles modeling of ferroelectric perovskite oxides over the past 30 years. We emphasize how the work done by a relatively small community on the fundamental understanding of ferroelectricity and related phenomena has been at the origin of consecutive theoretical breakthroughs, with an impact going often well beyond the limit of the ferroelectric community. In this context, we first review key theoretical advances such as the modern theory of polarization, the computation of functional properties as energy derivatives, the explicit treatment of finite fields, or the advent of second-principles methods to extend the length and timescale of the simulations. We then discuss how these have revolutionized our understanding of ferroelectricity and related phenomena in this technologically important class of compounds.

Experience Of Time

Young psychoactive substance users in social precarity are vulnerable to a range of health and social issues. Time perspective is one aspect to consider in supporting change. This study draws on the views expressed by young adults to portray their subjective experience of time, how this perception evolves and its implications for their substance use and socio-occupational integration trajectories. The sample includes 23 young psychoactive substance users ( M = 24.65 years old; 83% male) in social precarity frequenting a community-based harm reduction centre. Thematic analysis of the interviews reveals the past to be synonymous with disappointment and disillusionment, but also a constructive force. Participants expressed their present-day material and human needs as well as their need for recognition and a sense of control over their own destiny. Their limited ability to project into the future was also discussed. Avenues on how support to this population might be adapted are suggested.

Consequences Of Violence

The mid-1990s through the first decade of the new millennium marked an increase in publications pertaining to war and violence in the ancient past. This review considers how scholars of the past decade have responded to that work. The emerging consensus is that war and violence were endemic to all societies studied by archaeologists, and yet the frequency, intensity, causes, and consequences of violence were highly variable for reasons that defy simplistic explanation. The general trend has been toward archaeologies of war and violence that focus on understanding the nuances of particular places and historical moments. Nevertheless, archaeologists continue to grapple with grand narratives of war, such as the proposition that violence has decreased from ancient to modern times and the role of war and violence in state formation and collapse. Recent research also draws attention to a more expansive definition of violence. Expected final online publication date for the Annual Review of Anthropology, Volume 50 is October 2021.

Physical Principles

A surge in research focused on understanding the physical principles governing the formation, properties, and function of membraneless compartments has occurred over the past decade. Compartments such as the nucleolus, stress granules, and nuclear speckles have been designated as biomolecular condensates to describe their shared property of spatially concentrating biomolecules. Although this research has historically been carried out in animal and fungal systems, recent work has begun to explore whether these same principles are relevant in plants. Effectively understanding and studying biomolecular condensates require interdisciplinary expertise that spans cell biology, biochemistry, and condensed matter physics and biophysics. As such, some involved concepts may be unfamiliar to any given individual. This review focuses on introducing concepts essential to the study of biomolecular condensates and phase separation for biologists seeking to carry out research in this area and further examines aspects of biomolecular condensates that are relevant to plant systems. Expected final online publication date for the Annual Review of Plant Biology, Volume 72 is May 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Our global population is growing at a pace to exceed 10 billion people by the year 2050. This growth will place pressure on the agricultural production of food to feed the hungry masses. One category that will be strained is protein. Per capita protein consumption is rising in virtually every country for both nutritional reasons and consumption enjoyment. The United Nations estimates protein demand will double by 2050, and this will result in a critical overall protein shortage if drastic changes are not made in the years preceding these changes. Therefore, the world is in the midst of identifying technological breakthroughs to make protein more readily available and sustainable for future generations. One protein sourcing category that has grown in the past decade is plant-based proteins, which seem to fit criteria established by discerning consumers, including healthy, sustainable, ethical, and relatively inexpensive. Although demand for plant-based protein continues to increase, these proteins are challenging to utilize in novel food formulations.
