Carnivorous Plants Tropical Pitcher Plant Carnivorous Plants Most plants gather nutrients directly from the soil, but some plants can survive in low-nutrient habitats. Carnivorous plants live in areas with abundant sun and water, but with low levels of vital nitrogen in the soil. They have an incredible adaptation: the ability to trap and digest insects and small animals. Their leaves attract insects with bright colors and sweet nectar, once the insects arrive, the plants trap them in several ways: Pitfall traps, such as Adhesive traps, such as pitcher plants, trap sundews, have leaves with things in deep slippery glands on the ends of pools filled with stalks that have a sticky digestive enzymes. substance to grab small Photo: Damon Collingsworth Damon Photo: Photo: Damon Collingsworth Damon Photo: insects.

If you look closely, you’ll be able to see several examples of aerial roots inside this building. On woody trees and vines, such as the one pictured to the right, they can function as supports, helping to anchor the plant. Other aerial roots can help absorb moisture and nutrients. This allows plants, such as orchids, to live off of the forest floor on other plants and away from the fierce competition for space and sunlight. Some plants that live in wet marshes and bogs have underground roots but they need aerial roots to help with air exchange.

LOESCHEN,* CRAIG E. MARTIN,' * MARIAN SMITH,t AND SUZANNE L. EDERf •Department of Botany, University of Kansas, Lawrence, Kansas 66045-2106; and t Department of Biological Sciences, Southern Illinois University, Edwardsville, Illinois 62026-1651 The relationship between leaf anatomy, specifically the percent of leaf volume occupied by water- storage parenchyma (hydrenchyma), and the contribution of respiratory C02 during Crassulacean acid metabolism (CAM) was investigated in 12 epiphytic species of Tillandsia. It has been postulated that the hydrenchyma, which contributes to C02 exchange through respiration only, may be causally related to the recently observed phenomenon of C02 recycling during CAM. Among the 12 species of Tillandsia, leaves of T. usneoides and T. bergeri exhibited 0% hydrenchyma, while the hydrenchyma in the other species ranged from 2.9% to 53% of leaf cross-sectional area. Diurnal malate fluctuation and nighttime atmospheric C02 uptake were measured in at least four individuals of each species. A significant excess of diurnal malate fluctuation as compared with atmospheric C02 absorbed overnight was observed only in T. schiedeana. This species had an intermediate proportion (30%) of hydrenchyma in its leaves. Results of this study do not support the hypothesis that C02 recycling during CAM may reflect respiratory contributions of C02 from the tissue hydrenchyma.

  • 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.

    New Cultivars Keywords: Pinguicula ‘Riva’, Drosera binata ‘Ghost’, Nepenthes ampullaria ‘Black Widow’, Nepenthes ampullaria ‘Caramel Candy Stripe’, Nepenthes ampullaria ‘Lime Delight’, Nepenthes ampullaria ‘Chocolate Delight’, Nepenthes ampullaria ‘Cherry Delight’, Nepenthes ampullaria ‘Bronze Delight’. Pinguicula ‘Riva’ Submitted: 22 February 2018 The parents of Pinguicula ‘Riva’ (Fig. 1) are P. agnata (with scented flowers) × P. gigantea (to the best of my knowledge; the second parent may have been a P. gigantea × P. emarginata). This cross was done and the resulting seed germinated in late 2013 by me in San Francisco, California. This particular plant made its specialness apparent after about 2 years of growth under lights when it began flowering. The flower is approximately 2 cm wide by 2.5 cm long and is white with a bright yellow center which is surrounded by a flaring purple ring. The petals are 1 cm long, 7-9 mm wide, slightly ruffled, and the top 2 petals have irregular slightly serrated upper margins. The spur is 12 mm long, green and straight. The flower stalk is 18-20 cm long. And, the flower is scented, quite heavily in warmer conditions. The flower does not produce pollen or seed so it is sterile. The leaves of the plant are nice as well, ranging from 4-5.5 cm long and about 3 cm wide. The leaf shape is oblong egg-shaped with the rounded end distal from the central growth point. The color of the leaves ranges from pale green with burgundy tinting and margins to muted burgundy with green undertones. The margins of the leaf are slightly upturned.

    Technical Refereed Contribution Soil pH values at sites of terrestrial carnivorous plants in south-west Europe Lubomír Adamec • Institute of Botany of the Czech Academy of Sciences • Dukelská 135 • CZ-379 82 Trˇebonˇ • Czech Republic • [email protected] Keywords: Soil water pH, neutral soils, Pinguicula spp., Drosera intermedia, Drosophyllum lusitanicum. Abstract: Although the majority of terrestrial carnivorous plants grow in acidic soils at a pH of 3.5-5.5, there are many dozens of carnivorous species, mostly mountainous or rocky Pinguicula species, which grow preferen- tially or strictly in neutral or slightly alkaline soils at pHs between 7-8. Knowledge of an optimum soil pH value and an amplitude of this factor may be important not only for understanding the ecology of various species and their conservation, but also for successfully growing them. I report soil pH values at microsites of 15 terrestrial carnivorous plant species or subspecies in SW Europe. Introduction The majority of terrestrial carnivorous plants grow in wetlands such as peat bogs, fens, wet meadows, or wet clayish sands. The soils have usually low available mineral nutrient content (N, P, K, Ca, Mg), are hypoxic or anoxic and usually acidic (Juniper et al. 1989; Adamec 1997; Rice 2006). Unlike mineral nutritional character- istics of these soils, which have commonly been studied and related to carnivorous plant growth in the field or greenhouse experiments and which have also been published (for the review see Adamec 1997), relatively very little is known about the relationship between soil pH and growth of terrestrial carnivorous plants. Although some limited knowledge of soil pH at habitats of carnivorous plants or in typical substrates exist among botanists and growers (e.g., Roberts & Oosting 1958; Aldenius et al.

Mihail Sadoveanu, nr. 3, 700490–Iaşi, Romania Corresponding author: [email protected] This second part of the paper about the vascular flora of Rarău Massif listed approximately half of the whole number of the species registered by the authors in their field trips or already included in literature on the same area. Other taxa have been added to the initial list of plants, so that, the total number of taxa registered by the authors in Rarău Massif amount to 1443 taxa (1133 species and 310 subspecies, varieties and forms). There was signaled out the alien taxa on the surveyed area (18 species) and those dubious presence of some taxa for the same area (17 species). Also, there were listed all the vascular plants, protected by various laws or regulations, both internal or international, existing in Rarău (i.e. 189 taxa). Finally, there has been assessed the degree of wild flora conservation, using several indicators introduced in literature by Nowak, as they are: conservation indicator (C), threat conservation indicator) (CK), sozophytisation indicator (W), and conservation effectiveness indicator (E). Key words: Vascular flora, Rarău Massif, Romania, conservation indicators. 1. INTRODUCTION A comprehensive analysis of Rarău flora, in terms of plant diversity, taxonomic structure, biological, ecological and phytogeographic characteristics, as well as in terms of the richness in endemics, relict or threatened plant species was published in our previous note (see Oprea & Sîrbu 2012).
