Compact Grimmia

<em>Schistidium confertum</em>, commonly known as compact grimmia, is a small cushion-forming moss in the family Grimmiaceae. It belongs to a genus of rock-dwelling mosses widely distributed across cool temperate and boreal regions of the Northern Hemisphere. This species has been recorded from Luxembourg, Norway, Sweden, and the United States, typically colonising exposed siliceous and calcareous rock surfaces in open or lightly shaded environments. Compact grimmia typically forms dense, compact tufts or cushions closely adhering to rock faces, providing stability and retaining moisture in harsh, exposed habitats. Like other Schistidium mosses, it is adapted to periodic desiccation, able to survive extended dry periods and rehydrate rapidly when moisture returns. The species contributes to the ecological community of rock surface microhabitats, creating substrate for other microorganisms and serving as a component of biological soil and rock crusts. It is classified as Vulnerable by the IUCN in parts of its range, reflecting sensitivity to air pollution, acid deposition, and habitat disturbance, particularly in northwestern Europe where many moss species have declined. Biological traits including specific growth rates, reproductive biology, and detailed ecological requirements remain poorly documented compared to more widely studied bryophyte species. Conservation of compact grimmia depends on maintaining clean air quality and protecting undisturbed rock habitats from quarrying and recreational disturbance.

Scarlet Macaw

아메리카 대륙에서 가장 화려한 색을 자랑하는 새 중 하나인 붉은 마코앵무(Ara macao)는 선명한 빨강, 노랑, 파랑 깃털과 최대 1미터에 이르는 날개 폭을 지닙니다. 멕시코에서 볼리비아에 이르는 습윤한 저지대 숲에 서식하며, 지능이 높고 최대 75년을 살 수 있는 장수 동물로 평생 짝을 이루어 생활합니다. 씨앗의 독소를 제거하기 위해 미네랄이 풍부한 흙을 섭취하는 클레이 릭까지 장거리를 이동합니다. 최소관심 종으로 분류되지만 서식지 파괴와 애완동물 거래로 인해 지역적으로 위협을 받고 있습니다.
