Accepted 9 June, 2011 This study deals with the valorization of medicinal and aromatic plants of the Tunisian flora, in order to find new bioactive natural products. The essential oil constituents from the fruits of Ammi visnaga , collected from two Tunisian localities, Ichkeul and Djebba the North of Tunisia, were extracted by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS). Forty-one compounds were identified. Both samples showed similar chemical composition, the major components were linalool, isoamyl 2-methyl butyrate and isopentyl isovalerate.

Abstract Available plastomes of the Lauraceae show similar structure and varied size, but there has been no systematic comparison across the family. In order to understand the variation in plastome size and structure in the Lauraceae and related families of magnoliids, we here compare 47 plastomes, 15 newly sequenced, from 27 representative genera. We reveal that the two shortest plastomes are in the parasitic Lauraceae genus Cassytha, with lengths of 114,623 (C. filiformis) and 114,963 bp (C. capillaris), and that they have lost NADH dehydrogenase (ndh) genes in the large single-copy region and one entire copy of the inverted repeat (IR) region. The plastomes of the core Lauraceae group, with lengths from 150,749 bp (Nectandra angustifolia) to 152,739 bp (Actinodaphne trichocarpa), have lost trnI-CAU, rpl23, rpl2,afragmentofycf2, and their intergenic regions in IRb region, whereas the plastomes of the basal Lauraceae group, with lengths from 157,577 bp (Eusideroxylon zwageri) to 158,530 bp (Beilschmiedia tungfangen- sis), have lost rpl2 in IRa region. -
Biol B242 - Coevolution
BIOL B242 - COEVOLUTION http://www.ucl.ac.uk/~ucbhdjm/courses/b242/Coevol/Coevol.html BIOL B242 - COEVOLUTION So far ... In this course we have mainly discussed evolution within species, and evolution leading to speciation. Evolution by natural selection is caused by the interaction of populations/species with their environments. Today ... However, the environment of a species is always partly biotic. This brings up the possiblity that the "environment" itself may be evolving. Two or more species may in fact coevolve. And coevolution gives rise to some of the most interesting phenomena in nature. What is coevolution? At its most basic, coevolution is defined as evolution in two or more evolutionary entities brought about by reciprocal selective effects between the entities. The term was invented by Paul Ehrlich and Peter Raven in 1964 in a famous article: "Butterflies and plants: a study in coevolution", in which they showed how genera and families of butterflies depended for food on particular phylogenetic groupings of plants. We have already discussed some coevolutionary phenomena: For example, sex and recombination may have evolved because of a coevolutionary arms race between organisms and their parasites; the rate of evolution, and the likelihood of producing resistance to infection (in the hosts) and virulence (in the parasites) is enhanced by sex. We have also discussed sexual selection as a coevolutionary phenomenon between female choice and male secondary sexual traits. In this case, the coevolution is within a single species, but it is a kind of coevolution nonetheless. One of our problem sets involved frequency dependent selection between two types of players in an evolutionary "game". -

Husbandry Guidelines Broad-Headed Snake Hoplocephalus bungaroides Compiler – Charles Morris Western Sydney Institute of TAFE, Richmond Captive Animals Certificate III RUV3020R Lecturers: Graeme Phipps, Jacki Salkeld & Brad Walker 2009 1 Occupational Health and Safety WARNING This Snake is DANGEROUSLY VENOMOUS CAPABLE OF INFLICTING A POTENTIALLY FATAL BITE ALWAYS HAVE A COMPRESSION BANDAGE WITHIN REACH SNAKE BITE TREATMENT: Do NOT wash the wound. Do NOT cut the wound, apply substances to the wound or use a tourniquet. Do NOT remove jeans or shirt as any movement will assist the venom to enter the blood stream. KEEP THE VICTIM STILL. 1. Apply a broad pressure bandage over the bite site as soon as possible. 2. Keep the limb still. The bandage should be as tight as you would bind a sprained ankle. 3. Extend the bandage down to the fingers or toes then up the leg as high as possible. (For a bite on the hand or forearm bind up to the elbow). 4. Apply a splint if possible, to immobilise the limb. 5. Bind it firmly to as much of the limb as possible. (Use a sling for an arm injury). Bring transport to the victim where possible or carry them to transportation. Transport the victim to the nearest hospital. Please Print this page off and put it up on the wall in your snake room. 2 There is some serious occupational health risks involved in keeping venomous snakes. All risk can be eliminated if kept clean and in the correct lockable enclosures with only the risk of handling left in play. -

Living with Animals Conference Co-Organized by Robert W. Mitchell, Radhika N
Living with Animals Conference Co-organized by Robert W. Mitchell, Radhika N. Makecha, & Michał Piotr Pręgowski Eastern Kentucky University, 19-21 March 2015 Cover design: Kasey L. Morris Conference overview Each day begins with a keynote speaker, and follows with two tracks (in separate locations) that will run concurrently. Breakfast foods and coffee/tea/water will be available prior to the morning keynotes. Coffee breaks (i.e., snacks and coffee/tea/water) are scheduled between sequential groups of talks. Thus, for example, if one session is from 9:05-10:15, and the next session is 10:40-11:40, there is a coffee break from 10:15-10:40. Drinks and edibles should be visible at or near the entry to the rooms where talks are held. Book display: Throughout the conference in Library Room 201, there is a book display. Several university presses have generously provided books for your perusal (as well as order sheets), and some conference participants will be displaying their books as well. Thursday features the “Living with Horses” sessions, as well as concurrent sessions, and has an optional (pre-paid) trip to Berea for shopping and dinner at the Historic Boone Tavern Restaurant. Friday features the “Teaching with Animals” sessions throughout the morning and early afternoon (which includes a boxed lunch during panel discussions and a movie showing and discussion); “Living with Animals” sessions continuing in the late afternoon, and a Conference Dinner at Masala Indian restaurant. Saturday includes “Living with Animals” sessions throughout the day and Poster Presentations during a buffet lunch. In addition, there is the optional trip to the White Hall State Historic Site (you pay when you arrive at the site). -

Using diversity indices (Shannon-Wiener), plant knowledge is compared among communities (urban- rural population), and between sex (male-female) and age (older or younger than 40 years) categories within each community. Among our informants, we found quantitative differences concerning the knowledge of medicinal plants between sex and age categories. Some individuals play a key role relating to medicinal plant knowledge, and steps should be taken in order to include them in management and conservation plans. Key words: ethnobotany, diversity indices, plant knowledge and use, Rio Negro, Brazilian Amazon.
