Brown Rat

집쥐(Rattus norvegicus)는 IUCN 적색목록에서 관심대상(LC)으로 분류됩니다. 분포 범위 전반에 걸쳐 널리 서식하며 개체 수가 안정적으로 유지되고 있어 즉각적인 보전 우려가 없습니다.

<em>Comatricha nigra</em> is among the more widely distributed species in the genus <em>Comatricha</em>, with documented records from Asia, Europe, North America, and South America. It belongs to the class Myxomycetes, order Stemonitidales, and is recognized by its dark, stalked sporangia with a distinctive capillitium. The species grows on decaying wood, bark, and moist plant debris in forest habitats across its broad geographic range. As with all plasmodial slime molds, <em>C. nigra</em> undergoes a life cycle that includes a motile plasmodial feeding stage and a reproductive sporangial stage. The feeding plasmodium consumes bacteria, fungal spores, and organic particles, playing a role in nutrient cycling and decomposition. The global distribution of <em>C. nigra</em> reflects the capacity of slime mold spores to disperse over long distances via wind currents. No quantitative biological metrics are recorded, and the species has not been assessed by the IUCN.
