Nocturnal refers to organisms that are primarily active during the night and rest during the daytime. This behavioral adaptation is observed across numerous animal taxa and represents an evolutionary response to ecological pressures such as predation, temperature extremes, and competition for resources. In biological terms, nocturnality is governed by internal timekeeping systems known as circadian […]
Elatostema is a large genus of flowering plants in the family Urticaceae (the nettle family). The genus contains more than 350 species, many of which are native to tropical and subtropical regions of Asia, Africa, and Oceania. Members of Elatostema are often found in moist, shaded forest environments, thriving on the forest floor, riverbanks, and
Pando, also known as the Trembling Giant, is a massive clonal colony of a single male Quaking Aspen (Populus tremuloides) located in the Fishlake National Forest of Utah, United States. 🇺🇸 While it looks like a massive forest of individual trees, Pando is actually a single living organism connected by an expansive underground root system.
Kadimakara australiensis is an extinct species of marine reptile belonging to the clade Ichthyosauria, a group of dolphin-shaped reptiles that inhabited the world’s oceans during the Mesozoic Era. The species is known from fossil material discovered in South Australia and dates to the Early Jurassic period, approximately 190–180 million years ago. Originally assigned to the

Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. They are famous for their four-stage life cycle, large, often brightly colored wings, and conspicuous, fluttering flight. 🌸 As of 2026, butterflies remain vital bioindicators of ecosystem health, with scientists closely monitoring their migration and population patterns to study
Scoloposcelis is a genus of small predatory true bugs within the family Anthocoridae, commonly known as minute pirate bugs. Members of this genus are hemipteran insects characterized by piercing–sucking mouthparts and predatory feeding behavior. Though less widely recognized than some other anthocorid genera, Scoloposcelis species play a meaningful ecological role in regulating populations of small
Ecology is the scientific study of interactions among organisms and their physical environment. It examines the distribution, abundance, and relationships of living organisms, as well as the processes that govern ecosystems. The discipline bridges biology, environmental science, and earth systems, aiming to understand how life functions, persists, and responds to both natural and anthropogenic changes.
A species is the fundamental unit of biological classification, representing a group of organisms that share common characteristics and, under natural conditions, are capable of interbreeding to produce fertile offspring. The concept of species lies at the core of taxonomy, evolutionary biology, ecology, and conservation science. Although the term appears straightforward, defining what constitutes a
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus “habitat” is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which
