The Occurrence of Microorganisms in Grassland Soils
Soil microorganisms are responsible for the mineralization of organic compounds and the course of various biogeochemical cycles. They have an influence on the biodiversity of entire ecosystems, including the plant cover. They are responsible for the productivity of soil and its structure, and they also affect the circulation of elements in nature. The count and species composition of soil microorganisms depend mainly on the physicochemical properties of the pedon, the amount of nutrients, the type of soil, and the species composition of the plant community. Plants significantly influence the species composition of soil microbial communities through the release or loss of compounds from plant roots to the surrounding soil environment and decomposition of litter and roots.

The Physical Setting of Amazonian Floodplains
Amazonian floodplain forests along large rivers consist of two distinct floras that are traced to their differentiated sediment- and nutrient-rich (várzea) or sediment- and nutrient-poor (igapó) environments.

The Plastisphere Micro-Niche and Biodegradation
The particular characteristics of the plastic matrix, such as its floating ability and hydrophobicity, have created a new unique substratum for microbial colonization. The new micro-niche thus created becomes occupied by a specific biofilm called the plastisphere.

The Potential of Home Hydroponics
The global food system is facing significant challenges that make it unsustainable and environmentally harmful. These challenges not only threaten food security but also have severe negative impacts on the environment. In this context, hydroponics emerges as a sustainable, plant-based food production technique that can be employed as a solution in urban areas. It can be implemented in domestic microproduction systems, serving as a complementary alternative to conventional food production methods.

The Production of Rare Earth Elements
Rare earth elements (REE) are less than 20% of all elements naturally occurring in the environment. They are defined as a group of 17 elements comprising scandium (Sc), yttrium (Y), and lanthanum (La) elements of group 3B of Periodic Table, and the 14 elements of the lanthanides series, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu.

The Relevance of Perception in Landscape Framework
The relationship with bicycle infrastructure is lacking in current empirical research on user perceptions, which, on the contrary, studies emphasize aesthetic quality or visual surveys.  As the cycling infrastructure is a key area for commuting, shopping, entertainment, and recreation in urban communities, a thorough understanding of users’ perceptions of the environment is needed. Landscape and bicycle infrastructure cause a different perception as psychological factors interact based on the function of use. Bicycle spaces are small, enclosed, and lack contact with nature because they are often designed with inappropriate criteria. The bicycle infrastructure is seen in full harmony and potential with the landscape if there is contact with nature. These physical elements affect the sorts of landscape- or user-oriented policies and procedures that attempt to increase user satisfaction levels for the former and landscape promotion for the latter, in addition to cultural and psychological considerations.

The Role of Urban Green Infrastructure
The urban green infrastructure (UGI) is “an interconnected network of urban green spaces, including multiple types of natural or man-made systems, ranging from large-scale water or terrestrial ecosystems to small-scale pocket parks or green components, such as green walls in cities”. It provides ecosystems services that are highly important for human well-being in cities.

The Skeptical Environmentalist
The Skeptical Environmentalist: Measuring the Real State of the World (Danish: Verdens sande tilstand, literal translation: The True State of the World) is a book by Danish environmentalist author Bjørn Lomborg, controversial for its claims that overpopulation, declining energy resources, deforestation, species loss, water shortages, certain aspects of global warming, and an assortment of other global environmental issues are unsupported by statistical analysis of the relevant data. It was first published in Danish in 1998, while the English edition was published as a work in environmental economics by Cambridge University Press in 2001. Due to the scope of the project, comprising the range of topics addressed, the diversity of data and sources employed, and the many types of conclusions and comments advanced, The Skeptical Environmentalist does not fit easily into a particular scientific discipline or methodology. Although published by the social sciences division of Cambridge University Press, the findings and conclusions were widely challenged on the basis of natural science. This interpretation of The Skeptical Environmentalist as a work of environmental science generated much of the controversy and debate that surrounded the book.
