African elephant

아프리카코끼리(Loxodonta africana)는 지구상에서 가장 큰 육상 동물로, 최대 7,000 kg에 달하며 사하라 이남 아프리카의 사바나, 삼림, 습지에 서식한다. 뛰어난 지능을 가지며, 모계를 중심으로 한 복잡한 사회 구조를 이루고 초저주파음, 울음소리, 촉각을 통해 의사소통한다. 나무를 쓰러뜨리고 물웅덩이를 파며 씨앗을 산포하는 생태계 엔지니어로, 현재 취약(VU) 종으로 분류되며 상아 밀렵과 서식지 손실로 인해 개체수가 감소하고 있다.

Chrysolykos calceatus is a freshwater chrysophyte microalga in the genus Chrysolykos, class Chrysophyceae, order Chromulinales. The genus Chrysolykos belongs to the loricate chrysophytes, a group of golden algae enclosed within a rigid or semi-rigid outer case through which flagella emerge. The specific epithet calceatus — meaning shoed or boot-shaped — describes the characteristic shape of the lorica in this species, which resembles a shoe or boot in lateral profile, a morphology distinctive enough to separate it from the angular profile of C. angulatus and the flattened form of C. complanatus. C. calceatus has been recorded from Norwegian freshwater environments, part of the documentation of chrysophyte diversity in cold Scandinavian lake systems. Scandinavian oligotrophic lakes are important habitats for loricate chrysophytes, which thrive in their clear, low-nutrient waters during stratified warm seasons when competition from larger algae is reduced. The species is a nanoplankton organism engaged in photosynthesis using the chrysophyte pigment complement, and may additionally practice phagotrophy on bacteria and small organic particles. Stomatocyst formation — the production of siliceous resting cysts — is a feature shared across many chrysophytes and may occur in C. calceatus, providing resistance to unfavorable seasonal conditions such as winter ice cover or summer thermal stratification. C. calceatus has not been formally assessed under IUCN criteria and is classified as Not Evaluated. Documentation of this species contributes to knowledge of freshwater microalgal biodiversity in boreal and subarctic ecosystems.
