  • A pond-side water sample taken on 02/24/2024 using a small sample bottled attached to an extension pole Air temp 42F (no ice at the shore).

Unexpected movement inside the shell of a specimen of Arcella spectabilis (IDd by Bruce Taylor) revealed a highly metabolic, flagellated euglenoid. The Arcella shell appears intact, so the euglenoid must have entered through the shell's aperture... we just don't know why! Bruce Taylor suspects this is a species of the Astasia. For a long video of dubious quality, see https://youtu.be/_srdcoOyTaE.

Paramecium bursaria Ehrenberg from the acidic freshwater kettle pond Chatfield's Hole. Imaged in Nomarski DIC on Olympus BH2S using SPlan 100 1.25 oil immersion and Splanapo 40 0.95 objectives plus variable phone camera cropping on Samsung Galaxy S9+. The cells measure 120-146 um in length. This population is rather starved and most individuals have digested most of their Zoochlorella symbionts. I imaged one rotating well-fed free-swimming individual full of symbiont algae where we can see the three-dimensional relationship between macronucleus and micronucleus. I was able to closely image the contractile vacuoles which had collecting canals and 3 excretory pores. This is important to distinguish P. bursaria from a close congener, Paramecium (Viridoparamecium nov. subgen.) chlorelligerum Kahl 1935. Kreutz et al (2012) compared the two and found "Morphologically, P. chlorelligerum differs from P. (C.) bursaria, the second green species in the genus, by having a special swimming shape, the length of the caudal cilia, the size of the micronucleus, the size of the symbiotic algae, the contractile vacuoles (with collecting vesicles vs. collecting canals), and the number of excretory pores/contractile vacuole (1 vs. 2–3)" (1) .

PARAMECIUM BURSARIA Ehrenberg Length 90-150µm; foot-shaped, more or less flattened; uniform ciliation except for a group of long caudal cilia; green with symbiotic zoochlorellae; a long broad oral groove (vestibule) leads to the buccal cavity, the buccal ciliary apparatus is characterized by 2 " peniculi "; 1 macronucleus, 1 compact micro-nucleus; 2 contractile vacuoles; numerous prominent pellicular trichocysts. Diet-Food Bacteria (sometimes purple-coloured sulfur bacteria), flagellates; starving individuals digest their symbionts. Occurrence and ecology Cosmopolitan in distribution, e.g., Europe, North America, India, in still waters rich in higher plants and algae, such as ponds or littoral zones of lakes, forest pools rich in decaying leaves, oxidation ponds, polluted streams. Under laboratory conditions this ciliate occurs in cultures rich in peptone, under which conditions it can withstand high ammonium and low oxygen levels.

Paramecium bursaria is a mixotrophic ciliate species, which is common in stagnant and slow-flowing, nutrient-rich waters. It is usually found living in symbiosis with zoochlorellae (green algae) of the genera Chlorella or Micractinium. "Paramecium bursaria is one of only two species in the genus Paramecium that harbor algal endosymbionts. Based on a phylogenetic tree constructed from Paramecium 18S rRNA sequences with T. thermophila as outgroup, P. bursaria is the most diverged species since the most common Paramecium ancestor, which may explain why P. bursaria cell physiology is so distinct from other Paramecium species. In the wild, most P. bursaria cells stably harbor several hundred algal cells in the cytoplasm. Each algal cell is engulfed by a host-derived perialgal vacuole (PV) membrane that becomes attached to the host plasma membrane. Different species of algal endosymbionts have been identified in different strains of P. bursaria, suggesting that these strains may have evolved a preference for or compatibility with specific green algae" (2).

Trachelius ovum EHRENBERG, 1831 EHRENBERG, 1838 from the acidic freshwater kettle pond Chatfield's Hole. Imaged in Nomarski DIC on Olympus BH2S using SPlanapo 20 0.75 and Splanapo 40 0.95 objectives plus variable phone camera cropping on Samsung Galaxy S9+. The cells measure 240 um in length. The following discussions and several figures are adapted from Foissner et al (1995) (1).

According to EHRENBERG (1838), FOISSNER & FOISSNER (1988b) and KAHL (1931a), Trachelius ovum has several safe synonyms, which do not appear in the saprobiological literature: T. cicer SCHRANK- this older synonym was never used and should therefore be suppressed forever for reasons of stability, T. vorax EHRENBERG, Amphileptus rotundus MASKELL, Trachelius Leidyi FOULKE. The exact organization of this common ciliate was previously insufficiently known, although it was reported several times and has been processed using modern methods (DRAGESCO & DRAGESCO-KERNEIS 1986, FRYD VERSAVEL et al. 1975, SONG & WILBERT 1989). The representations are too schematized and incorrect in detail. We have therefore reworked T. ovum for the “Atlas”. This showed that the somatic and oral ciliation is very similar to that of Dileptus. Nevertheless, Trachelius is clearly demarcated from Dileptus namely by the ventro-lateral fossa, where the ciliation is slightly modified and the club-shaped mouth funnel, which consists of a thick layer of the finest fibrils.

Congener comparison: Trachelius subtilis PENARD, which has not yet been sufficiently confirmed, has only 12 contractile vacuoles and no suction cup. Dileptus species usually have a clearly pointed rear end and are always much slimmer. Paradileptus elephantinus lives predominantly in the pelagic of stagnant waters and has a rosary-shaped (moniliform) macronucleus. The characteristics are particularly important for identification are 2, 3, 4 .

Differential diagnosis
1) Size in vivo 200-600 x 75-350 um, usually 250-350 um long.
2) Shape sac-shaped to almost spherical, starving specimens clearly flattened on one side. Proboscis often only about 1/4-, rarely up to 1/2-length, usually curved dorsally. In well fed specimens it becomes a short, stalk-shaped extension. Ventro-laterally a small, difficult to recognize pit that serves as a suction cup.
3) Macronucleus dumbbell-shaped, often disintegrates into a few spherical parts in postconjugates. Several micronuclei.
4) Many small contractile vacuoles scattered throughout the cell. Plasma very strongly vacuolated, the strands form a coarse network.
5) Short, rod-shaped extrusomes in the proboscis along the ridge of the mouth. Cortex thick, with many ellipsoid granules.
6) About 80-120 longitudinal rows of cilia, some of which extend into the ventro-lateral fossa, where there are several specializations, which are explained in the figure legends. Brush 3-4 rows, on the dorsal side of the trunk, a row extending almost to the end of the body; only clearly visible after silver impregnation and in the scanning electron microscope.
7) Mouth entrance at the base of the proboscis, surrounded by many very delicate bars that form a club-shaped, thick-walled funnel. To the right of the circumoral row of eyelashes there is a longitudinal row of cilia, on the left there are many short oblique rows of perioral cilia; more precise structure of the oral cilia can only be recognized after silver impregnation.
