Abstract

Birds, or avians, are living organisms classified in the animal kingdom and share characteristic features such as a body covering of feathers that enables them to fly. Birds are also a biodiversity asset that needs to be conserved and preserved due to their significance and roles in human life. Samudra University, with its expansive grounds adorned with various trees, provides a potential habitat for birds. This research, conducted in October-November 2023, aims to explore the diversity of bird species within the Samudra University area. The study employs a quantitative descriptive method, covering four locations, Location I in the Faculty of Agriculture, Location II by the sea, Location III in the Student Building, and Location IV in the Faculty of Primary School Teacher Education. The findings reveal four avian species from four families in the Samudra University area: Passer montanus, Ardea alba, Geopelia striata, and Todirhampus chloris. The avian diversity index in that area is considered moderate.

Abstract

Stomata, which are specialized cells on the surface of leaves, undergo modification to form structures containing two guard cells. These cells play a crucial role in facilitating the exchange of water vapor and gases between the plant's internal environment and the surrounding atmosphere. Typically located on plant parts exposed to air, such as leaves, stems, and rhizomes, stomata distribution varies among different species. While some plants exhibit stomata on both upper and lower leaf surfaces, others, like water lilies, exclusively feature stomata on the upper side.The objective of the current investigation was to analyze the stomatal anatomy of various plant species within the Euphorbiaceae family. Employing a qualitative descriptive approach, the study aimed to characterize and interpret the stomatal types present on the leaves of Euphorbiaceae plants in the Langsa City region. The findings revealed the presence of five Euphorbiaceae species in Langsa City, including Euphorbia mili (jade fern), Jatropha curcas (Jatropha curcas), Codiaeum variegatum 'Norma' (norma puring), Codiaeum variegatum Bi (jet puring), and Codiaeum finger (finger puring), all of which exhibited parasitic stomatal types.
