Abstract

Air pollution in urban areas triggered by vehicle emissions and industrial activities requires biological monitoring methods capable of demonstrating the cumulative impact of pollutants. Orthetrum sabina is a dragonfly species characterized by high mobility yet territorial behavior, making it highly effective as a bioindicator of air quality within specific areas. The biomonitoring focus on this species lies in its ability to absorb and store heavy metal residues and atmospheric particulates in its wing and thorax tissues during the adult phase. The complex nature of its cuticle allows for the clear recording of air pollutant deposits, providing data that is more representative than fluctuating physical air measurements. This species is known for its resilience, long-term exposure to high atmospheric pollutants can affect its wing morphology and flight patterns. O. sabina is not merely an inhabitant of the ecosystem but a reliable "natural sensor" for assessing air health quality. The utilization of this species as a biomonitoring model is expected to facilitate the mapping of air pollution zones in urban areas more efficiently and economically.

Abstract

Nepenthes ampullaria is a unique species of pitcher plant due to its detritivorous nature and tendency to grow in clusters on the forest floor. This study aims to examine the reproductive biology of N. ampullaria, including flower morphology, flowering phenology, and pollination systems. The research was conducted using descriptive observational methods in its natural habitat. The results showed that N. ampullaria is dioecious, where male and female flowers are found on different individuals. The flowering process begins with the emergence of inflorescence buds that develop into flower clusters. Pollinator activity, dominated by nocturnal and diurnal insects, plays a crucial role in the success of fertilization. In addition to sexual reproduction through seeds, this species also demonstrates strong vegetative reproduction capabilities through basal shoots. Understanding this reproductive biology is essential as a basis for ex-situ conservation efforts and the cultivation development of this carnivorous plant.
