The guppy (Poecilia reticulata) is one of the most widespread and extensively studied freshwater species, originating from South America. Its use as a model organism in evolutionary biology and behavioral ecology renders it scientifically significant. Morphological Characteristics Guppies exhibit sexual dimorphism【1】. Males are typically 2–3 cm in length and display vibrant colors and elongated caudal fins. Females are larger (4–6 cm) and have duller coloration. The male’s anal fin is modified i

Loss of Biodiversity refers to the decline or complete disappearance of the genetic, species, and ecosystem-level diversity of living organisms on Earth. Biological diversity is a composite of genetic diversity, which encompasses genetic variation; species diversity, which includes all organisms in a given area; and habitat diversity, which arises from varied environmental conditions. Today, this diversity has increased to hundreds of times the natural extinction rate predicted by geological rec

Mavigöl is a natural lake system located within the boundaries of the Dereli district in Giresun province, in Türkiye’s Black Sea Region. It is distinguished by its saline composition and turquoise coloration. The waterfall is situated on the Göksu Stream, and the area is home to the Black Sea’s only saline stream. Mavigöl consists of four distinct lakes and is surrounded by rocky terrain, with the local geology enabling the formation of travertine deposits. Formation and Natural Structure The M

World Elephant Day is an international observance held annually on August 12. Initiated in 2012, this day aims to raise awareness of the threats facing African and Asian elephants and to support conservation efforts. Elephants play a vital role in maintaining ecosystem balance but face human-induced threats such as illegal poaching, habitat loss and exploitation in the tourism industry.

Coypu (Myocastor coypus) is a mammalian species belonging to the order Rodentia and the family Myocastoridae, adapted to a semi-aquatic lifestyle. Native to South America, this species has been introduced to various continents due to human-driven translocations primarily for fur and meat production, and has been classified as an invasive species in several regions. Due to its distinctive morphological structure and environmental impacts, this animal occurs in limited populations in wetland areas
