Abstract This study presents a thorough examination of the chemical properties inherent to soil, with a focus on the unique context of Bangladesh. Soil functions are intricately linked to its chemical composition, which plays a vital role in determining agricultural productivity and ecological vitality. The soil within Bangladesh's geographical boundaries is characterized by its richness and fertility, contributing significantly to its agricultural output and overall ecosystem health. By delving into the chemical properties of Bangladeshi soil, this review aims to enhance our understanding of this dynamic ecosystem. Insights gained from this exploration can shed light on factors influencing soil fertility, nutrient availability, and overall ecosystem health, thereby informing strategies for sustainable land management and agricultural practices in Bangladesh and beyond.

Abstract Acanthodactylus savignyi is one of Algeria's endemic and rare reptile species. A population of this species has been identified in a new locality within the Sidi Bel Abbes region in the Northwest of Algeria. This study provides a brief description of the species in this explored area, highlighting its ecological significance and potential conservation needs.

Abstract A 41% of arthropod species are declining, and one-third of all species are threatened by extinction. Changes in land use are recognized as the primary cause of this decline. The scarcity of data for the Southern Hemisphere is partly due to limited funding but particularly due to the hyperdiversity of tropical regions. The objective of this study was to investigate the presence of this issue in scientific articles and the contribution of insects to the total number of threatened species in Argentina. Globally, the percentage of articles related to insect extinctions in Google Scholar has grown exponentially over the past twenty years, from 0.42% in 2000 to 6% in 2021. However, no significant growth was found in the number of articles on this topic in Argentina during the study period. Currently, only 23 insect species are recognized as at risk out of a total of 572 threatened species according to the "IUCN Red List of Threatened Species" for Argentina. These species belong to the orders Odonata (8), Coleoptera (1), Lepidoptera (2), Hymenoptera (11), and Orthoptera (1 species), representing only 4% of the total threatened species. In comparison, it is estimated that 26% and 27% of threatened species in the much less diverse faunas of Germany and the United Kingdom, respectively, are insects. These results suggest that the percentage of endangered insects in Argentina is being underestimated due to taxonomic and population knowledge gaps, consistent with reports by other authors. In hyperdiverse countries like ours, only molecular techniques can process large samples quickly enough to obtain estimates of insect diversity before they disappear.

Abstract Calotropis procera (Aiton) R. Br. is an important flowering desert plant species. C . procera   is a broad-leaf, evergreen, soft wooded, perennial shrub of the family Apocynaceae and subfamily Asclepiadaceae (the milk weed family). C. procera is playing a positive economic and ecological role in the harsh climatic conditions of the arid and semi-arid regions. The different parts (leaves, fruits, flowers, bark, stem, whole part) of C. procera have been used traditionally in medicine, agriculture, and industry for since long period of human beings. The germination and growth ability of C. procera attributed to the well adaptation in variant environmental and dry climatic conditions. C. procera utilized successfully differently, such as in traditional medicine, fodder, and fuel purposes, phytoremediation, petro plant (biogas), biofuel, source of hydro carbon and synthesis of nanoparticles. The utilization of C. procera as a source of bioenergy also assisting in the uplift the economy of some poor countries. The traditional used for the treatment of asthma, cough, diarrhea, malaria, cancer, dysentery jaundice, rheumatism, fever, dysentery, diabetes, and many skin disease problems in human beings. The published research article data was searched from different electronic engines, including English databases, Google, Google Scholar, NIH (National Library of Medicine), Conbio (Society for Conservation of Biology), PubMed and Science direct. The goal of this review was to search and analyze the research articles available covering the period 1981–2024 on the ethnobotanical properties on C. procera.   The C. procera is playing a helping role in balancing the desert ecosystem due to its better adaptation potential to such diverse climatic conditions. Many researchers have reported that the change of climatic conditions, scarcity of water, indiscriminate discharge of various types of toxic pollutants, overgrazing, and some natural activities have been the main reasons of decline of this plant species since last couple of decade very rapidly. The present review findings would be helpful for conservation groups, ecologist, nongovernmental organizations, and governmental sectors, researchers, land manager, environmental manager and field management, industrial sectors and pharmaceutical sectors are working on this aspect at regional and international levels.

Abstract Albizia lebbeck (L. ) Benth. is an economically  important multipurpose flowering woody tree species and helps in environmental management. The different parts (leaves, fruits, flowers, bark, stems, whole parts) of A. lebbeck used in medicine, agriculture, and industry traditionally for a long period of human civilization. A. lebbeck traditionally utilized in medicine, fodder, and phytoremediation. The traditional medicine is used for the treatment of asthma, cough, diarrhea, malaria, cancer, dysentery, jaundice, rheumatism, fever, dysentery, diabetes, and many skin disease problems in human beings.   A few investigations have studied the phytochemicals of A. lebbeck plant material and its biological activity and active constituents and revealed the presence of protein, carbohydrates, minerals, and fatty acids, along with the prevalence of minerals and vitamins. The germination and growth abilities of A. lebbeck respond differently to the immediate environmental conditions.  A. lebbeck is playing a helping role in balancing the desert ecosystem due to its better adaptation potential to such diverse climatic conditions. Many researchers have reported that the change in climatic conditions, scarcity of water, indiscriminate discharge of various types of toxic pollutants, overgrazing, and some natural activities have been the main reasons of decline of this plant species since the last couple of decades. The goal of this review was to search and analyze the scattered research articles information available on the ecological properties of A. lebbeck In this regard, the  published research article data was searched from different electronic engines, English as Google, Google Scholar, NIH (National Library of Medicine), Conbio (Society for Conservation of Biology), PubMed and science direct covering the period 1965–2024. The present review findings would be helpful for conservation groups, ecologists, nongovernmental organizations, governmental sectors, researchers, land managers, environmental managers, field managers, industrial sectors, and pharmaceutical sectors that are working on this aspect at regional and international levels.
