On the Polymorphism of Cyanogenesis in Lotus Corniculatus L
Heredity (1983) 51 (3), 537—547 1983. The Genetical Society of Great Britain ONTHE POLYMORPHISM OF CYANOGENESIS IN LOTUS CORNICULATUS L. IX. SELECTIVE HERBIVORY IN NATURAL POPULATIONS AT PORTHDAFARCH, ANGLESEY S. G. COMPTON, S. G. BEESLEY AND DAVID A. JONES Unit of Genetics, University of Hull, Hull HU6 lAX Received1O.iii.83 SUMMARY The L. corniculatus populations at Porthdafarch are polymorphic for the charac- ters of leaf cyanogenesis, petal cyanogenesis and keel petal colour. Plants with cyanogenic leaves and petals occur less frequently on the sea cliffs than inland and previous studies have obtained circumstantial evidence of a link between the dine in leaf cyanogenesis and the distribution of selectively grazing molluscs. Counts of leaf and petal damage have confirmed that plants on the cliffs are grazed less heavily than those growing inland and have demonstrated that individuals with acyanogenic leaves or petals are liable to be chewed more heavily than their cyanogenic neighbours. Most of the damage was attributable to feeding by molluscs and it is concluded that herbivorous insects have only a minor role in the maintenance of the dines. 1. INTRODUCTION The population of Lotus corniculatus L. on the cliff along the S. W. facing coast of Porthdafarch, Holy Island, Anglesey contains a lower proportion of plants with cyanogenic leaves than two nearby populations less than 200 metres inland (Jones, 1962). Because this dine appeared to have been stable for several years and the two inland sites had essentially the same proportions of cyanogenic plants, in spite of being topographically very different, Ellis et a!., (1977) sought those environmental factors common to the inland sites by which they differed from the cliff site. -

ABSTRACT : Lotus corniculatus L. (Fabaceae), commonly known as bird's foot trefoil, is a forage plant. It possesses cytotoxic, anti-inammatory, antibacterial and antifungal activity. The plant contains benzoic acid, transilin, isosalicin, soyasaponin I, dehydrosoyasaponin I, medicarpin-3-O-β-D-glucopyranoside, pharbitoside A and p-coumaric acid. This review article provides information on the pharmacological activities of Lotus corniculatus L. KEYWORDS : Lotus corniculatus L, Bird's-foot, cytotoxic. INTRODUCTION Lotus corniculatus L. is a perennial legume, popular in temperate leaets obovate–elliptic, usually blunt. Stipules vestigial. climates for pasture, hay and silage production[1]. All the parts of the plant contain cyanogenic glycosides(hydrogen cyanide)[2]. In Fruit:Straight,narrow,round,brown,opening,spreadingpod small quantities, hydrogen cyanide has been shown to stimulate (legume). respiration and improve digestion, it is also claimed to be of benet in the treatment of cancer. In excess, however, it can cause respiratory failure and even death. The owers of some forms of the plant contain traces of prussic acid and so the plants can become mildly toxic when owering[3]. Bird's-foot-trefoil grows to between 5 and 35 cm (2 and 13.5 inches) high, and from June to September produces bright yolk-yellow pea- like blooms that are often patterned with streaks of red (hence the “bacon and eggs” reference in one of its many common names). The “birds-foot” in the plant's most common name refers to the claw- like arrangement of its black seed pods, while trefoil comes from the leaves, which at rst glance appear to consist of three separate Figure 1: Lotus corniculatusL. -

Insects and Plants in the Pollination Ecology of the Boreal Zone
Ecological Research (1993) 8, 247-267 REVIEW Insects and plants in the pollination ecology of the boreal zone P. G. KEVAN,1 E. A. TIKHMENEV2 AND M. Usux1 1 Department of Env, ronmental Biology, University of Guelph, Guelph, Ontario, N1G 2W1, Canada and 2 Institute for Biological Problems of the North, Academy of Sciences, K. Marx Pr. 24, Magadan, 685000 Russia Pollination systems in the boreal zone range from generalist to specialist, both entomologically and botanically. The relative importance of wind pollination, insect pollination, sexual separation between and within plants, and between flowers, hermaphroditism of flowers, and various breeding systems are related to plant growth form and habitat. The diversity and specializations of anthophilous insects parallel those in other bioge0graphic zones, but seem less developed. We suggest that this reflects the combined effects of evolutionary youth, severity of climate, restriction of symbiont ranges within those of their hosts, and the naturally frequent perturbations by fire or insect outbreaks in the zone, requiring faunal and floral vagility and constraining specialization in mutualism. Modern perturbations by logging and pesticides seem to be well buffered because of the relative openness of the ecosystem (compared to others), although damage has been documented. Insect pollination is as much a keystone process in the boreal forest as elsewhere, despite the immediate counter-impression given by the dominance ofwind-pollinated conifers. Nevertheless, there are few studies, botanical or entomological in situ. The boreal system offers important opportunities in general and applied research in pollination ecology and synecology generally. Key words: anthecology; boreal; floral biology; pollinators; taiga.

The ranks are scaled from 0 to 100, with 0 representing a plant that poses no threat to native ecosystems and 100 representing a plant that poses a major threat to native ecosystems.

Stems are erect to trailing, branched, introduced legume. Yellow sweetclover can be glabrous to sparsely hairy, and 10 to 80 cm long. Leaves distinguished from birdsfoot trefoil by the presence of are alternate and pinnately compound with five leaflets trifoliate leaves, flowers that are arranged in many- each, resembling the foot of a bird. Leaf axes are 2 to 5 flowered terminal and axillary racemes, and corollas that mm long. Leaflets are asymmetrical, elliptic to obovate, are 4 to 7 mm long (DiTomaso and Healy 2007, 5 to 20 mm long, and 4 to 10 mm wide with pointed tips Klinkenberg 2010). and minutely toothed margins. The lowest pair of leaflets are basal and somewhat reduced in size. The three terminal leaflets arise from the tip of the main axis. Flowers are arranged in axillary umbels in groups of two to eight. -
