Rebman, was quoted as saying, ³Vermin. Rats with horns. Evil,² as he hiked across a rugged volcanic island about 150 miles west of Mexico¹s Baja California peninsula, adding, ³I could keep going. They¹ve really eaten nearly everything.² Rebman, curator of botany at the San Diego Natural History Museum, is, this story explained, referring to the some 10,000 goats that have transformed the lush forest of Guadalupe Island into a barren field since they were introduced by sailors some 150 years ago. Now he and his colleagues are, this story says, searching for the few remaining endemic plants that may have escaped the marauding herd. This story explained that along with Thomas Oberbauer, a botanist from the San Diego Planning Department, and José Delgadillo of Universidad Autónoma de Baja California in Ensenada, Rebman digs plants out of crevasses and scales cliffs to snip out-of-reach shrubs. They find, this story says, one honeysuckle plant that may never have been seen before on the island, but that¹s about it. Guadalupe Island once was, according to this story, home to more unique plants than any other island on North America¹s Pacific Coast: 34, a count that rivaled the biological diversity of the Galápagos Islands. But since the goats arrived, 26 of the island¹s 156 native plants have, this story explained, gone extinct, including six found nowhere else in the world. Half of the island¹s pine trees have, this story explained, disappeared since the late 1960s, unable to reproduce because goats eat the seedlings. This story continued to explain the devastation that has resulted from the introduction of non-native species and some thoughts about how to salvage what is left before it is too late. LETTER TO THE EDITOR; SMART MICE August 2000 Scientific American Elliot Noma, Metuchen, N.J., wrote in this letter to the editor: In ³Building a Brainier Mouse,² Joe Z. Tsien notes that mouse intelligence is limited by NMDA receptor properties but that these properties can be modified to increase memory, apparently without undesirable side effects. Although he was cited as explaining why the ability to memorize decreases for older mice, Tsien does not address why natural selection has not further increased the time that the receptor is open (thus enhancing memory formation) for both juveniles and adults. Could, this letter asks, such an enhancement lead to physiological side effects, or might the resulting higher intelligence lead to nonadaptive behavioral strategies? Such drawbacks would have, according to this letter, fascinating implications for the development and administration of memory-boosting drugs. Tsien replies: Levels of learning and memory are, according to this reply, not solely determined by the opening duration of the NMDA receptors. It is highly likely that other molecules and different levels in complexity of neural network and circuits in the brain play a significant role in determining these mental capacities. The influx of calcium through the NMDA receptor is, this story explained, critical, but too much of it may cause brain cells to die. Evolution may, this story says, have already selected for the receptors to stay open longer but only up to the point at which the organism becomes sexually mature and reproduces. ABOLITION OF MINK HUNTS WILL HURT RIVERSIDE July 11, 2000 The Electronic Telegraph Duke of Wellington, Stratfield Saye, Hants, wrote in this letter to the editor: Amid all the present hoo-ha about the proposed abolition of foxhunting, I wonder whether such bodies as the RSPB and the National Trust have given any thought to the effect on riverside populations of wildlife should a prohibition on ³hunting with dogs² also apply to mink hounds. This letter explained that the mink, an introduced species, is an inveterate and indiscriminate killer of all forms of fauna found near rivers. Water voles, baby otters, waterfowl of all sorts, frogs, ground-nesting birds and even fish all succumb to the voracious appetite of the mink. (The author speaks from a considerable personal knowledge of controlling mink, going back nearly 40 years.) In the Sixties, a mink farm near a river the author knows well in Scotland closed down and some animals escaped or were released into the wild. Within a year or two there was, according to this letter, a large feral population on the river and, within a very short time, the otter population disappeared and there was a noticeable decrease in ducks, waterails, oystercatchers and other riverside birds. A concentrated campaign of trapping and shooting dealt with the problem and now we see otters again and the bird population has, according to this letter, recovered. However, this letter explained, in much of England, especially the southern counties, such measures are not effective because withy and reed beds and side streams disperse the water over a much larger area, and trapping and shooting are ineffective. A few years ago, the author saw a mink here on the Loddon. The author had no idea we had any, but it accounted for the fact that our water vole population, once abundant, is virtually non-existent now. The author immediately contacted the mink hounds and they got two mink. Since then, they have visited us at least once a year and always kill one or two. The author is convinced that the abolition of mink-hunting packs of hounds would lead to widespread depredation of ground-nesting birds and fauna in southern English rivers. Otters are, according to this letter, making a comeback in many areas but mink could be a serious deterrent to successful re-establishment, as mink kill young otters. POLICE PROBE CAT KILLINGS IN HAWTHORNE July 11, 2000 The Los Angeles Times Jessica Garrison http://www.latimes.com/print/metro/20000711/t000065070.html This story explained that when her granddaughter¹s cat Oreo turned up dead in her neighbor¹s Hawthorne frontyard, Patricia Cheatham assumed it had fallen victim to the dreaded neighborhood pit bull. Rick Villafana thought his mother¹s cat, Pretty Boy, missing for two weeks, had, this story says, found better digs. Roger Martinez was cited as figuring the dead cat on his lawn had been hit by a car. But a grimmer picture has, according to this story, emerged in their quiet neighborhood of neat lawns and well-tended flowers. Police were cited as reporting that at least three and perhaps as many as 25 intentionally killed‹and sometimes dismembered and decapitated‹cats have been left on lawns in the last few weeks, most within a half-mile-square area between 130th and 135th streets around Hawthorne Boulevard. Police were cited as deducing that the cats were being killed elsewhere with a sharp implement, either a surgical tool or a knife, and placed in the yards in the early morning. As news of the killings spread through the neighborhood, the Police Department was flooded with calls from more than 20 people who were cited as saying that they, too, had found dead and, in most cases, dismembered cats on their front lawns but had discarded them without reporting them to police. Police are, according to this story, following up on several tips received over the last week. Many neighbors, meanwhile, have been cited as saying that they are keeping their cats indoors. KIDS CAN¹T GET ALL THEIR CALCIUM NEEDS FROM VEGGIES July 11, 2000 The Toronto Star Zannat Reza, MHSc, RD, Registered Dietitian and Nutrition Educator, Dairy Farmers of Ontario, Mississauga, wrote in this letter to the editor re: The Natural Path column (June 30) about children not needing to drink milk. As a registered dietitian, it concerns Reza when nutrition advice not based on scientific evidence is given to members of the public. Reza would like to address some incorrect statements about milk that were featured in that column. The coulmn was cited as claiming that 70 per cent of the world¹s population doesn¹t drink milk. However, it fails, according to this letter, to mention that many cultures drink the milk of other animals including camels, goats, buffaloes and yaks. Also, milk is, this letter explained, used to prepare various foods such as kefir (Balkans), kheer (India), laban (Middle East) and cheeses in numerous countries. Contrary to what the column was cited as saying, milk is not the leading cause of ear infections or allergies. Infants are, according to this letter, just as likely to be allergic to soy, peanuts and eggs. This letter further explained that milk allergies affect only 2 to 3 per cent of infants, 80 per cent of whom outgrow the allergy by the time they are 3 years old. The column also was cited as refering to the Nurses Health Study conducted by researchers at Harvard stating that there was no benefit to drinking milk for osteoporosis and that drinking milk increased hip fractures. It is, this letter explained, important to note that the Nurses Health Study is observational in nature and does not establish cause and effect. Also, the researchers themselves were cited as stating that, ³We have no reason to believe that dairy calcium itself was responsible for the observed increase in risk of hip fracture; rather, some other characteristic of women who consume dairy foods or some other nutrients or non-nutrient compound of dairy foods might have contributed to the elevated risk.² In a follow-up article the researchers were cited as focusing on the vitamin D gene, thus suggesting a different factor in the relationship. As for children getting their calcium from vegetables, this is, according to this letter, simply not practical. While green leafy vegetables are nutritious foods they are, this letter notes, not the best source of calcium. For example, a child would have to eat four cups of broccoli to get the same amount of calcium in one cup of milk. Milk also has, according to this letter, other bone-building nutrients such as vitamin D, protein, magnesium, phosphorus and vitamin A that work with calcium to build bones.

ELK FARMING July 10, 2000 Kitchener-Waterloo Record Jim Romahn This story explained that they look so graceful, deer raising their sleek necks, pointing their regal noses and pricking their curious ears. It¹s no wonder, according to this story, that Dr. John Pollard and his wife, Dr. Marie-Claire Plante, love working with elk and red deer at their 100-acre farm near Ponsonby, which is between Guelph, Elora and Fergus. The elk in this field are, this story explained, unusual. They are, this story says, the first in the world to be born as the result of in vitro fertilization and frozen embryos. It¹s a technological triumph for Pollard and Plante and it is also a practical advance because it means purebred elk breeders can raise several fawns per mature female instead of the normal one per year. Pollard was cited as explaining that elk present one egg per year and they do that in the fall giving them only one chance to mate with a bull. The conception rate is, this story says, 98 to 99 per cent, which is phenomenal. Dairy farmers would, this story explained, be delighted to achieve 80 per cent conception rates on the first try. What Pollard and Plante have done in the private laboratory they have built on their farm is, this story explained, find a way to gather unfertilized eggs from mature elk females and then they add semen that has been gathered from a bull. At the one-week stage, the embryos are hardy enough to withstand freezing and can be saved until precisely the right time to put them into the womb of another animal‹in this case into lower-priced red deer, which are close relatives of elk. Elk breeders have been cited as showing keen interest in this research because a purebred female sells for $6,000 to $10,000 whereas red deer can be had for $1,000. There¹s a good profit to be made in using $1,000 mothers to raise $6,000 fawns. CONCERN FOR SHOT RACEHORSES July 10, 2000 BBC http://news.bbc.co.uk/hi/english/sci/tech/newsid_819000/819015.stm The humane slaughter of animals is, according to this story, a difficult field. Researchers were cited as saying that the UK¹s racing authorities need to review the methods used to put injured racehorses to sleep. At the moment, it is, this story says, mandatory for a silencer to be attached to any gun used to euthanase the animals, preventing racegoers from hearing a distressing bang. But a study completed at De Montfort University, Lincoln, was cited as suggesting the use of such an attachment may make it more difficult for the bullet to damage the part of the brain that will result in the most effective kill possible. The scientists were cited as saying that there is a theoretical risk that some of the horses shot using a silencer could recover a degree of consciousness - although they concede this is highly unlikely. Nevertheless, Daniel Mills, a senior lecturer in animal welfare, was cited as saying that the Jockey Club, racing¹s governing body, should investigate the design of a new, purpose-built weapon that will ensure the animals are destroyed in a way that leaves no room for doubt. Daniel Mills was quoted as telling BBC News Online, ³Some of the weapons used on racecourses are adapted from revolvers where the gases escape from the back of the gun and the silencer makes no difference to the sound whatsoever. It just makes the instrument much more difficult to handle and harder to effect a satisfactory kill. We are not saying hundreds of horses are suffering, we are just saying this is an issue of concern that requires further investigation.² The immediate purpose of shooting a horse is, this story explained, to render the animal unconscious. If the job is done properly, the bullet from the gun will, this story says, damage the brainstem, interfering with the horse¹s respiratory and heart functions and preventing the animal from waking up again. Haemorrhaging in the brain and a build-up of pressure may, this story notes, also have the same, desired outcome. But the positioning of the gun just above the eyes and the angle at which it is held are crucial and if the barrel deviates from the ideal line, the bullet may miss its brainstem target. Daniel Mills, and his colleague Gary Millar, have been cited as conducting research which suggests this happens quite often. In 15 horses killed by an expert knackerman, they were cited as finding that only five of the animals to have suffered clear and extensive brainstem damage. Daniel Mills one of the researchers were cited as saying that the silencers used on racecourses can only make the task of hitting the brainstem more difficult, adding, ³The silencers lengthen the barrel, increase the weight and affect the balance of the weapon.² They was quoted as writing in the Veterinary Record, ³Rather than using adapted weapons, they should manufacture a weapon specifically for the job.² ŒServiceable and effective¹ Dr Peter Webbon, the Jockey Club¹s Chief Veterinary Adviser, was cited as saying that the Lincoln study was an ³excellent piece of research² that had produced a number of surprises from which all veterinarians could learn. But he was further cited as saying that in his view, the use of a silencer could actually improve the accuracy of the shot, adding, ³If you have a silencer fitted to the gun then any hand movement is clearly going to influence the trajectory of the bullet. That¹s basic geometry. But if you are trying to aim in a particular direction, it is actually easier to do it with a slightly longer barrel. It is easier to work the line.² Dr Webbon was cited as saying that a bigger market for humane killers would almost certainly result in a better weapon than the ones currently in use, adding, ³If one accepts that there is a place for the gun in euthanasing horses, then I think the sound-moderated weapon which is generally in use on racecourses today is a very serviceable and effective weapon.² Many veterinarians were cited as thinking that shooting is the most effective way of putting a big animal like a horse to sleep. This story explained that lethal injection is possible but large volumes of chemicals are required to complete the task and administering these to a frightened and excited animal that is also in pain can be extremely difficult. The gun can, this story explained, also be the only means of euthanasia open to hunt kennelmen or knackermen who cannot legally use intravenous techniques and for whom a poisoned carcass has no value. Daniel Mills was quoted as saying, ³The humane slaughter of animals is an extremely difficult field which a lot of people want to deny exists but it is also an area where there is enormous potential to make a difference.² To subscribe to AnimalNet, send mail to: (subscription is free) listserv@listserv.uoguelph.ca leave subject line blank in the body of the message type: subscribe animalnet-L firstname lastname i.e. subscribe animalnet -L Doug Powell To unsubscribe to AnimalNet, send mail to: listserv@listserv.uoguelph.ca leave subject line blank in the body of the message type: signoff animalnet-L For more information about the AnimalNet research program, please contact: Dr. Douglas Powell dept. of plant agriculture University of Guelph Guelph, Ont.
