as a Source of Natural Pesticides
The extensive use of pesticides may negatively affect human health. Additionally, it is one of the main reasons for the decline of pollinators and is thus a hazard for most crops and biodiversity as a whole. Good candidates for the replacement of pesticides with ones less toxic to humans and pollinators are natural products (bioactive compounds extracted from plants), even though it should be kept in mind that some of them can be toxic too. Ailanthus altissima (Mill.), swingle, known also as tree of heaven, (Simaroubaceae) is one of the most aggressive alien invasive plants. It demonstrates a high tolerance to various habitat conditions and a potent propagation ability. This plant has a prominent ability to suppress the seed development of local vegetation.

B. bagarius (Hamilton, 1822) is a fish species that has huge potential as food and game fish in Bangladesh, Bhutan, India, and Nepal, but is encountering the threat of extinction in Bangladesh and throughout the world, which can be inferred from its alarming conservation status in Bangladesh as well as throughout the world. It is known as “Baghair” or “Bagh mach” in Bangladesh. In Bangla, the term “Bagh” refers to a tiger.

Agriculture and Pollinator Biodiversity
Pollinator biodiversity is greatly affected by industrialized agriculture practices. Agroecological alternatives for food production must be implemented.

Agroecology-The Case of Cereals
Transformative agroecology has been recognized as a stepping stone to achieving several Sustainable Development Goals (SDGs), due to its great potential to build climate change-resilient farming systems while enhancing ecosystem services and reducing biodiversity loss. Understanding the agroecological elements that underlie the sustainability of an agroecosystem is an urgent matter, serving as the foundation for designing a truly transformative agroecosystem.

Alien Insect Species for Food and Feed
While the use of alien insect species for food and feed can help to alleviate protein shortage and provide for a more sustainable feed production, their invasive potential should be considered.

Antimicrobial Mediterranean Wild Edible Plants
Mediterranean wild edible plants (MWEPs) and their antimicrobial properties have been known from ancient times, and nowadays, a growing number of people have rediscovered them as natural remedies for common infections. One of the problems concerning their use is the heterogeneity of the protocols used to extract and analyze the properties of their active principles; such heterogeneity still marks the overall set of scientific studies on MWEPs, not to mention the enormous heterogeneity that characterizes the properties of plants at the outset. We reviewed the current literature on medicinal value of Mediterranean native edible plants trying to emphasize both the weaknesses and the opportunities of these plants. The majority of the reviewed MWEPs can inhibit both Gram-negative and Gram-positive bacteria, and fungi.

Beavers, Bugs and Chemistry
The North American beaver (Castor canadensis Kuhl) and cottonwoods (Populus spp.) are foundation species, the interactions of which define a much larger community and affect a threatened riparian habitat type.

Biology Conservation of Olive Ridley Marine Turtles
Marine turtles are considered to be necessary for a healthy ocean, as they have a direct impact on other species. The olive ridley (Lepidochelys olivacea) is the most abundant of all seven sea turtles, found across the tropical regions of the Atlantic, Pacific, and Indian Oceans in over 80 different countries all around the globe.

Biomarker Studies in Stress Biology
Endpoints assessed at the population or community level are most often the result of the sum of effects on individuals, arising from the effects at the cellular and molecular levels. Within this framework, these lower biological level endpoints are more responsive at an early stage of exposure, making them potential toolboxes to be used as early-warning markers to address stress. Given this, by linking responses and understanding organisms’ metabolism and physiology, the possibilities for the use of biomarkers in stress biology are vast.

Butterfly Community Diversity in the Qinling Mountains
The Qinling Mountains are one of the oldest mountain ranges in China and a global biodiversity research and conservation hotspot. However, there is a lack of systematic research and survey of butterfly diversity in this region. Based on the butterfly taxa, combined with the changes in natural climate, altitude gradient and season in the Qinling Mountains, the butterfly diversity and community structure changes in 12 counties in the middle Qinling Mountains were analyzed by transect surveys and platform data analyses. A total of 9626 butterflies were observed, belonging to 427 species across 175 genera and 5 families. The species richness on the southern slope of the Qinling Mountains is higher than that on the northern slope.
