When it rains, sometimes it's better to just get wet—especially when staying dry could mean being digested alive. That's the hard lesson for insects hiding from showers underneath the lid of the slender pitcher plant (Nepenthes gracilis). During a downpour, the carnivorous plants, native to the Sunda region of Southeast Asia, rely on heavy raindrops crashing on top of their lids to help catapult shelter-seeking insects into their tube-shaped, fluid-filled leaves, researchers report online today in PLoS ONE. Like a diver jumping on a swimming pool springboard, the pounding raindrops create vibrations throughout the lid that launch insects off its underside and directly into an awaiting acid bath. Previously, scientists thought the lid simply prevented rainwater from diluting the leaf's digestive pool. But upon further investigation, researchers realized the structure's prey-capturing function. The underside of the lid has evolved to be covered with wax crystals which interfere with the adhesive pads found on an insect's feet.

- Ants in my plants! Nepenthes Ventrata has suddenly become the center of attention for a colony of small Ants. They are sucking up the sugar exuded by the nectar glands strategically placed on various parts of the plant. The ridged rim/lip of the pitcher is called the peristome and this too secretes a sugar nectar. Several times today I watched the ants working on the plant and I would say that 80% of the ants that explored the peristome eventually fell into the pitcher! One of these pitchers had at least fifty ants in it by 7PM this evening. Yikes!

- Spirostomum caudatum S. Caudatum (syn. Enchelis caudata OF Muller, 1786) has an ovoid macronucleus, similar to that of S. Teres, and a peristome roughly 1/4 (or slightly less) of body length. The species is easily distinguished by its extremely long, thin "tail."
- Vorticellid with microconjugant Sessile peritrichs conjugate in an unusual way. First, a "stalked" adult divides asymmetrically, producing a small, specialized cell called a microconjugant. This miniature *** fiend forms on one side of the "parent's" body, then swims away to find a mating partner. When it locates a suitable candidate -- a sessile adult, or "trophont," no different in appearance from others, but ready and willing to conjugate -- it attaches itself to the side of its larger lover and begins merging with it. In the course of a day, or so, the smaller cell disappears into the larger one, and the genetic material of the two organisms is combined, in the usual way of ciliates (micronuclei divide, haploid pronuclei merge, the old macronucleus is destroyed and a new one is formed) . The merged cell then goes on to divide by ordinary symmetrical fission, as peritrichs are commonly seen to do. (see Finley, 1943) This video shows a species of Vorticellid (either Vorticella or Pseudovorticella: I couldn't see the pellicle at high magnification, so can't be sure which), with a microconjugant attached to its side. I don't know enough about the morphology of the mating form to determine whether this video shows the unequal fission of one zooid or a conjugation between two specimens. I am inclined to think it is the latter, because, during the time I observed it (forty minutes or so), the area of contact between the two zooids appeared to increase, and the microconjugant seemed to be sinking into the ...

- Nepenthes, Tropical Pitcher Plant care, Carnivorous Plants Nepenthes are found in Southeast Asia, their largest distribution being the island of Borneo. Nepenthes are tropical pitcher plants which grow as scrambling or climbing vines. Their pitchers form at the end of a tendril which extends from each leaf. Not every leaf will produce a pitcher. At the opening around the pitcher there is a slippery liplike peristome. Around the peristome large amounts of nectar are produced to attract insects . The nectar has an intoxicating affect on many insects. They then fall into the pitcher were the fluid at the bottom of the pitcher is usually fairly neutral in pH. When an insect starts to struggle to get out, it signals the pitcher to secrete acids and enzymes in large amounts. The pH in the pitcher drops quickly and in a few day the insect is dissolved. The plant then reabsorbs the nutrient rich fluid.
- Pseudovorticella elongata (Fromentel, 1876) Pseudovorticella is very similar to Vorticella, but members of the genus have a reticulate (netlike) silverline system in the pellicle of the cell. In some species, this is quite conspicuous. Pseudovorticella monilata, for instance, looks as if were covered in little beads. In some species, however, the reticulate patterns in the pellicle are difficult to see. In Pseudovorticella elongata, the silverline system is very delicate and finely meshed, and should be visible only in DIC microscopy (Leitner & Foissner, 1997). However, while looking at this specimen in oil immersion at 1000X, I found it was possible to just barely make out the patterns in the pellicle that mark this as a Pseudovorticella. At 1:36, I've inserted a still photo with enhanced contrast to show this pattern, which somewhat resembles a faint honeycomb, or a wavy brick wall. Unfortunately, in the transition from my computer to YouTube the (already mediocre) video quality deteriorated further, and it is difficult to see the details. Pseudovorticella elongata (Fromentel, 1876) was known, for more than a century, as Vorticella elongata. Its most prominent feature is the long, cylindrical shape of the zooid, as illustrated by both Fromentel and Kahl. However, according to Leitner and Foissner, who redescribed the species in 1997, and moved it to the genus Pseudovorticella, this shape is a symptom of distress. Apparently, the slightest pressure from the coverslip causes the cell to assume this cylindrical form ...
- Stentor pyriformis The name means "pear-shaped Stentor," and the description is apt. The dozen or so individuals I watched were all free-swimming, sluggishly contractile and packed with zoochlorellae. Macronucleus consists of two or more isolated spheres. I could not see pigment granules, so I ruled out S. amethystinus. Nonetheless, some specimens are extremely dark (almost black, under normal brightfield illumination) From Mer Bleu bog, in mid September. 200X & 400X objectives
- Pseudoblepharisma tenue var. viride A long ciliate which resembles Spirostomum, but is smaller, less contractile, and has a relatively short peristome (1/4 to 1/6 of body length). This sub-variety of the species harbours symbiotic green algae (zoochorellae), which enable it to live in very anoxic conditions. These were found in the lowest stratum of a tall jar filled with water from the Mer Bleue sphagnum bog. Body length ~250-325 µm Collected in late October, 2012.

- Campanella anatomy, part 2 (annotated details) I few days ago I posted a video highlighting a few features of Campanella umbellaria. Here is another, showing the myoneme fibres, and the ciliate's unusual adoral membranes, which spiral around the peristome multiple times before plunging into the long, ciliated tube of its cytopharynx. The myonemes -- the longititudinal fibres that enable Campanella to contract its body -- are difficult to see in vivo. Here we see only the more prominent myonemes around the lip of the peristome. In addition to these, Campanella has a system of longer, more delicate fibres extending along the entire body, from mouth to stalk. (See Shi et al (2004), Infraciliature and Myoneme System of Campanella umbellaria.) Finally, at the end of the video there's a brief look at the aboral ciliary wreathe (aka trochal band, or locomotor fringe). The fringe on this specimen is almost fully developed, so it is possible that this one was apprehended in the process of transforming into a teletroch (its cylindrical swarming form of the ciliate). It did break away from its stalk a few minutes after I started recording it. Not all free-swimming Campanella are telotrochs, however; stalkless bodies can also swim, using their oral cilia for movement, rather than their posterior wreathe. From Mer Bleue bog, Ottawa. Collected in late October, 2012.

- Spirostomum; Amazing Microscopic Creature! HD 1080p! Spirostomum is a genus of free-living ciliate protists, belonging to the class Heterotrichea. Species of Spirostomum are found in both salt and fresh water. All are elongated, flexible and highly contractile. Although unicellular, members of some species can grow as long as 4 mm (0.16 in). The body of the cell is long and worm-like. In cross section it is mainly cylindrical, but may be flattened at the tail end. The posterior excretory vacuole is large, and may fill the whole "tail." Cilia on the cell body are short and arranged in longitudinal rows. The length of the peristome varies between species, from about 1/4 to as much as two 2/3 the length of the cell. The peristome is fringed with membranelles, which are used to channel particles of food into the creature's oral cavity. The macronucleus may be moniliform (like a string of beads) or compact and oval, depending on the species. Spirostomum reproduces by binary fission. Reproduction may be purely a***ual, or it may follow conjugation, during which compatible mating individuals come together and transfer genetic material across a cytoplasmic link. Members of the genus are extremely contractile. When startled, Spirostomum ambiguum can contract to less than half its extended length within 1/200 of a second (a contraction speed similar to that of the ciliate Vorticella). As it contracts, the cortex of the cell twists and widens, and its spiral structure becomes visible. The mechanism of Spirostomum's contractility was ...

- Spirostomum minus Spirostomum minus Roux 1901 is smaller and more slender than S. ambiguum, and has a shorter peristome. Ciliation runs spirally around the cell body. The macronucleus is moniliform (like a string of beads), and there is a large contractile vacuole in the tail. It is sometimes synonymised with S. intermedium. The peristome in S. minus is normally 1/3 to 1/2 the length of the body. This one seems exceptionally short.
- Insect adhesion: ant-eating plants Under the rim of a carnivorous pitcher plant such as this, nectar lures ants to visit for a tasty treat. When the rim is dry: the ants can climb on and around the plant with no problem. When the rim is wet: unluckily for the ants, the rim has a special microstructured hydrophilic surface; air humidity or rain can easily form a very thin water layer. Most ants aquaplane to their doom, where they are destined to stew in the plant's digestive juices. Video courtesy of Dr Holger Bohn at the University of Freiburg, Germany.
