Foraging Modes of Carnivorous Plants Aaron M
Israel Journal of Ecology & Evolution, 2020 http://dx.doi.org/10.1163/22244662-20191066 Foraging modes of carnivorous plants Aaron M. Ellison* Harvard Forest, Harvard University, 324 North Main Street, Petersham, Massachusetts, 01366, USA Abstract Carnivorous plants are pure sit-and-wait predators: they remain rooted to a single location and depend on the abundance and movement of their prey to obtain nutrients required for growth and reproduction. Yet carnivorous plants exhibit phenotypically plastic responses to prey availability that parallel those of non-carnivorous plants to changes in light levels or soil-nutrient concentrations. The latter have been considered to be foraging behaviors, but the former have not. Here, I review aspects of foraging theory that can be profitably applied to carnivorous plants considered as sit-and-wait predators. A discussion of different strategies by which carnivorous plants attract, capture, kill, and digest prey, and subsequently acquire nutrients from them suggests that optimal foraging theory can be applied to carnivorous plants as easily as it has been applied to animals. Carnivorous plants can vary their production, placement, and types of traps; switch between capturing nutrients from leaf-derived traps and roots; temporarily activate traps in response to external cues; or cease trap production altogether. Future research on foraging strategies by carnivorous plants will yield new insights into the physiology and ecology of what Darwin called “the most wonderful plants in the world”. At the same time, inclusion of carnivorous plants into models of animal foraging behavior could lead to the development of a more general and taxonomically inclusive foraging theory. -

Introduction There are approximately 700 identified species of carnivorous plants placed in 15 genera of nine families of dicotyledonous plants (Albert et al. 1992; Ellison & Gotellli 2001; Fleischmann 2012; Rice 2006) (Table 1). In India, a total of five genera of carnivorous plants are reported with 44 species; viz. Utricularia (38 species), Drosera (3), Nepenthes (1), Pinguicula (1), and Aldrovanda (1) (Santapau & Henry 1976; Anonymous 1988; Singh & Sanjappa 2011; Zaman et al. 2011; Kamble et al. 2012). Inter- estingly, northeastern India is the home of all five insectivorous genera, namely Nepenthes (com- monly known as tropical pitcher plant), Drosera (sundew), Utricularia (bladderwort), Aldrovanda (waterwheel plant), and Pinguicula (butterwort) with a total of 21 species. The area also hosts the “ancestral false carnivorous” plant Plumbago zelayanica, often known as murderous plant. Climate Lowland to mid-altitude areas are characterized by subtropical climate (Table 2) with maximum temperatures and maximum precipitation (monsoon) in summer, i.e., May to September (in some places the highest temperatures are reached already in April), and average temperatures usually not dropping below 0°C in winter. -

Deletion of Cephalotus Follicularis from Appendix II
Prop. 11.6 CONVENTION ON INTERNATIONAL TRADE IN ENDANGERED SPECIES OF WILD FAUNA AND FLORA A. PROPOSAL Deletion of Cephalotus follicularis from Appendix II. B. PROPONENT Commonwealth of Australia (Environment Australia) C. SUPPORTING STATEMENT The monotypic genus Cephalotus is an insectivorous plant endemic to south western Australia. It occurs on wetland margins throughout the southwest corner of Western Australia. This portion of Western Australia has a high rainfall and as a result there are extensive areas of suitable habitat, especially on the south coastal plain. Within its range are large areas of government owned forests, National Parks and other reserves where the species is common and is likely to occur in vast numbers. The species is easily propagated from small segments of rhizomes and, as a result, it is commonly traded and is widely cultivated. Morphological variation in wild populations is not evident. As the species is easily propagated, it is unlikely that cultivated stocks are derived from wild collections. Cephalotus follicularis has been identified by the CITES Plants Committee under the Ten Year Review as a candidate for deletion from Appendix II as there has been no recorded trade in wild taken specimens since the species was listed. The proposal received full endorsement of the 5th meeting of the CITES Plants Committee in Mexico, May 1994. 1. Taxonomy 1.1. Class Magnoliatae 1.2. Order Rosales 1.3. Family Cephalotaceae 1.4.

Giant Cephalotus of Unknown Origins
Giant Cephalotus of unknown origins Dick Chan • P.O. Box 2252 • Pasadena • California 91102 • USA • [email protected] Introduction I have been growing Cephalotus follicularis for over 20 years. Initially, I was obsessed with grow- ing specimen-type Cephalotus of different clones and to prove once-and-for-all that this was not a difficult plant to grow. Countless plants have met their demise as I experimented with various meth- ods of cultivation. For those that have survived and flourished, I noticed one plant in particular that grew larger, more vigorous, and had a different pitcher/leaf morphology than Cephalotus ‘Hummer’s Giant’ and the typical Cephalotus. However, I do not believe this plant to be just a better-grown speci- men of ‘Hummer’s Giant’. Through the years, I have given and sold this plant to individuals calling it the “Bubble Giant”, however, I have not received nor heard any feedback as to the well-being of those plants. So, for those reading this article and have received this plant from me, I would appreciate seeing some photos. For the remainder of this article, this plant will be referred to as the “unknown”. Origins During my initial spark-of-entry into the hobby, I started collecting Cephalotus cuttings, plants, stems, and leaves from anyone who had the plant and was willing to give or sell a piece to me. Be- cause of that activity, this plant is of an unknown origin because of the feverish pace by which I went about amassing what I had hoped would become a genetically diverse collection of plants. -
Towards Resolving Lamiales Relationships
Schäferhoff et al. BMC Evolutionary Biology 2010, 10:352 http://www.biomedcentral.com/1471-2148/10/352 RESEARCH ARTICLE Open Access Towards resolving Lamiales relationships: insights from rapidly evolving chloroplast sequences Bastian Schäferhoff1*, Andreas Fleischmann2, Eberhard Fischer3, Dirk C Albach4, Thomas Borsch5, Günther Heubl2, Kai F Müller1 Abstract Background: In the large angiosperm order Lamiales, a diverse array of highly specialized life strategies such as carnivory, parasitism, epiphytism, and desiccation tolerance occur, and some lineages possess drastically accelerated DNA substitutional rates or miniaturized genomes. However, understanding the evolution of these phenomena in the order, and clarifying borders of and relationships among lamialean families, has been hindered by largely unresolved trees in the past. Results: Our analysis of the rapidly evolving trnK/matK, trnL-F and rps16 chloroplast regions enabled us to infer more precise phylogenetic hypotheses for the Lamiales. Relationships among the nine first-branching families in the Lamiales tree are now resolved with very strong support. Subsequent to Plocospermataceae, a clade consisting of Carlemanniaceae plus Oleaceae branches, followed by Tetrachondraceae and a newly inferred clade composed of Gesneriaceae plus Calceolariaceae, which is also supported by morphological characters. Plantaginaceae (incl. Gratioleae) and Scrophulariaceae are well separated in the backbone grade; Lamiaceae and Verbenaceae appear in distant clades, while the recently described Linderniaceae are confirmed to be monophyletic and in an isolated position. Conclusions: Confidence about deep nodes of the Lamiales tree is an important step towards understanding the evolutionary diversification of a major clade of flowering plants. The degree of resolution obtained here now provides a first opportunity to discuss the evolution of morphological and biochemical traits in Lamiales. -

Technical Refereed Contribution Several pygmy Sundew species possess catapult-flypaper traps with repetitive function, indicating a possible evolutionary change into aquatic snap traps similar to Aldrovanda Siegfried R. H. Hartmeyer and Irmgard Hartmeyer • Weil am Rhein • Germany • s.hartmeyer@ t-online.de • www.hartmeyer.de Keywords: Drosera, pygmy Sundew, Aldrovanda, Dionaea, Droseraceae, Collembola, carnivorous plant, catapult-flypaper trap, snap trap, snap-tentacle, functional morphology, phylogeny. Abstract: Approximately 50 species of pygmy Sundews (genus Drosera, section Bryastrum) occur in the South of Australia and one each in New Zealand (D. pygmaea) and Venezuela (D. meristo- caulis). They grow mainly as small stemless rosettes possessing minute trapping leaves of 1-2 mm diameter with prominent marginal tentacles, or have elongated erect stems. The caulescent species possess only mucus-producing tentacles that are most effective in capturing small flying insects. The acaulescent species in contrast are specialized on crawling prey (Verbeek & Boasson 1993) and have developed mucus-free snap-tentacles (Fig. 1), able to bend surprisingly rapidly towards the leaf center. They lift prey like, e.g. springtails (Collembola) from the ground and carry it with a 180°-movement from the periphery of the plant onto the sticky leaf. Our examinations brought to light that several small species of section Bryastrum are able to catapult small animals even within fractions of a second. If the whole leaf is touched, several or even all marginal tentacles perform such bending movements simultaneously. We documented this behavior on video, featured on our film “Catapults in Pygmyland” on YouTube (www.youtube.com/watch?v=5k7GYGibdjM). Our results prove that more than only one species in the genus Drosera possess rapidly moving catapult-flypaper traps and that the examined pygmy catapults show a further specialization and function repeatedly (in contrast to the one-shot snap tentacles of D. -

Byblis in cultivation in the tropics and in temperate climates Gregory Allan • Birmingham • United Kingdom • [email protected] Cindy Chiang • Singapore • [email protected] This article has been written based mostly on the authors’ experiences in growing Byblis in the UK and in Singapore. It is hoped that growers in regions with different climates will be able to extrapo- late from the information provided here, adjusting the methods described below to suit their own growing conditions. Hopefully much of the information provided here is universal in its application. Introduction If any genus of carnivorous plants deserves to be better known, both by horticulturalists and botanists, it is Byblis. The common name (ironically rarely used by enthusiasts) for the genus is “rainbow plants”, on account of the prismatic effect that can be produced when the sun shines on their copiously-produced sticky glands. All species follow a basic morphological plan: they have a central stem from which radiate numerous filiform leaves and scapes with showy flowers that typi- cally have purple petals (although white forms of most species are known) and vivid yellow anthers. Virtually all parts of the plants are covered in mucilage-tipped stalked glands (colloquially referred to as “tentacles”), which efficiently capture small insects, as well as microscopic sessile digestive glands. Another interesting characteristic of the genus is the presence of pulvini in most, if not all, species. Pulvini are swellings at the base of pedicels which, usually after successful pollination, uti- lize hydraulics to bend the pedicel, and consequently the developing fruit, downwards towards the ground. This phenomenon was discovered by Brian Barnes in the early 21st century.
