Ardilla Gris Oriental

동부회색다람쥐(Sciurus carolinensis)는 북아메리카 동부가 원산지이나 유럽을 비롯한 여러 지역에 성공적으로 도입된 중형 수목성 설치류로, 몸무게는 최대 600g에 달합니다. 매 가을 수천 개의 견과류와 씨앗을 땅에 묻어 저장하며, 잊어버린 저장소에서 의도치 않게 나무를 발아시키는 역할을 합니다. 영국에서는 먹이 경쟁에서 우위를 점해 토착종인 붉은다람쥐를 대부분 대체했습니다.

Chrysococcus punctiformis is a unicellular freshwater chrysophyte microalga in the genus Chrysococcus, class Chrysophyceae. The specific epithet punctiformis — meaning point-shaped or dot-like — likely references the diminutive size of this species relative to other Chrysococcus species, or alternatively describes a distinctive punctate surface pattern on the lorica visible under microscopy. In Chrysococcus, the lorica is the primary taxonomic structure, and its form, texture, and any ornamentation distinguish species from one another. C. punctiformis has been recorded from Norwegian and Swedish freshwater environments, extending also to Brazilian localities. This broad distribution spanning subarctic Scandinavian lakes and tropical or subtropical South American water bodies suggests either genuine cosmopolitan dispersal of this species through passive mechanisms, or convergent morphological evolution that has been misidentified as the same taxon in different regions. Molecular phylogenetic data would help resolve this question. The species inhabits the limnetic zone of freshwater systems, where it functions as a primary producer and component of the nanoplankton community. Chrysococcus species are characteristic members of oligotrophic lake phytoplankton in Scandinavia, often co-occurring with other chrysophytes, diatoms, and chlorophytes. C. punctiformis uses chlorophylls a and c along with fucoxanthin for photosynthesis and may practice mixotrophic nutrition. It has not been assessed under IUCN criteria and is listed as Not Evaluated.
