Title Valsequillo biostratigraphy. III: Equid ecospecies in Paleoindian sites Type Journal Article
Year 2000 Publication Anthropologischer Anzeiger; Bericht Uber die Biologisch-Anthropologische Literatur Abbreviated Journal Anthropol Anz
Volume 58 Issue 3 Pages 275-298
Keywords Animals; *Ecology; Horses/*classification; Mexico; *Paleodontology; Species Specificity
Abstract Greater precision in North American Pleistocene equid taxonomy makes it now possible to exploit the ubiquitous horse remains in Paleoindian sites as ecological index-fossils. The horses of Central Mexico and the Southern Plains can be sorted by tooth size alone, except for two rare large horses of the Southern Plains. The species endemic to these grasslands and south to Central Mexico are Equus pacificus (large), E. conversidens (small), E. francisci (smallest). The Southern Plains were also occupied by a specialized grazer E. excelsus (Burnet and Sandia caves) and E. occidentalis (Dry and Sandia caves). West of the Rocky Mountains E. occidentalis was dominant. East of the Mississippi River two woodland species are found: E. fraternus and E. littoralis.

Title Feeding patterns of Triatoma vitticeps in the State of Rio de Janeiro, Brazil Type Journal Article
Year 2000 Publication Revista de Saude Publica Abbreviated Journal Rev Saude Publica
Volume 34 Issue 4 Pages 348-352
Keywords Animals; Brazil; Cattle; Chagas Disease/transmission; Dogs; Ecology; Feeding Behavior/physiology; Female; Food Habits/physiology; Humans; Insect Vectors/*physiology; Male; Triatoma/*physiology; *Trypanosoma cruzi/isolation & purification
Abstract OBJECTIVE: Feeding patterns of triatomines have contributed to elucidate its biology. Triatoma vitticeps, naturally infected with T. cruzi, has been found in domiciles. Its behavior and epidemiological patterns were investigated. METHODS: One-hundred and twenty two specimens of T. vitticeps were captured from February 1989 to April 1993 in two areas of Triunfo municipality, a subdistrict of Santa Maria Madalena municipal district, State of Rio de Janeiro, Brazil. The insects were dissected and their intestinal contents were removed and tested. It was used antisera from: man, cow, horse, dog, pig, armadillo, opossum, rodent, and bird. RESULTS: From the total analyzed, 79 were positive and 43 were negative to the nine antisera tested: armadillo (30.3%) > human and pig (13.1%) > bird and dog (11.5%) > horse (5.7%) > opossum (4.9%) > rodent (4. 1%) > cow (3.3%). Blood meals ranged from 0 to 4 and 6 in the following distribution: 0 = 25.41%; 1 = 45.08%; 2 = 10.66%; 3 = 6. 56%; 4 = 1.64%, and 6 = 0.82%. Nine of the 122 insects captured were not examined, 74 (65.54%) were positive for T. cruzi infection and 39 (34.51%) were negative. CONCLUSIONS: These results identified the T. vitticeps as being a sylvatic species and trypanosomiasis as being an enzootic disease. Epidemiological vigilance will be important to provide more information regarding the behavior of the species

Title A wavelet-based metric for visual texture discrimination with applications in evolutionary ecology Type Journal Article
Year 1995 Publication Mathematical Biosciences Abbreviated Journal Math Biosci
Volume 126 Issue 1 Pages 21-39
Keywords Animals; Carnivora; *Ecology; Equidae; *Evolution; Humans; Mathematics; Models, Biological; Moths; *Pattern Recognition, Visual; Pigmentation
Abstract Much work on natural and sexual selection is concerned with the conspicuousness of visual patterns (textures) on animal and plant surfaces. Previous attempts by evolutionary biologists to quantify apparency of such textures have involved subjective estimates of conspicuousness or statistical analyses based on transect samples. We present a method based on wavelet analysis that avoids subjectivity and that uses more of the information in image textures than transects do. Like the human visual system for texture discrimination, and probably like that of other vertebrates, this method is based on localized analysis of orientation and frequency components of the patterns composing visual textures. As examples of the metric's utility, we present analyses of crypsis for tigers, zebras, and peppered moth morphs.

Title Preliminary note on the distribution and ecology of Culicoides imicola in Portugal Type Journal Article
Year 1993 Publication Medical and Veterinary Entomology Abbreviated Journal Med Vet Entomol
Volume 7 Issue 1 Pages 23-26
Keywords Animals; *Ceratopogonidae; Ecology; Population Density; Portugal
Abstract Data on Culicoides imicola were obtained during studies carried out during the recent outbreak of African horse sickness in Portugal. The previous most northerly published record of C. imicola in Portugal was 38 degrees 40'N (Pegoes). In the present work the geographical distribution of this species is extended to the parallel of 41 degrees 17'N. We have also confirmed the continuous presence of adult C. imicola in Southern Portugal (Alentejo and Algarve) throughout the year. In the laboratory we obtained this species from a sample of cattle faeces and from another of soil contaminated with animal excreta. In relation to host association 57.37% of C. imicola were trapped in the vicinity of pigsties. Finally, we collected 11,463 Culicoides of which 12.47% were C. imicola.

Title Unravelling the ecology of influenza A virus Type Journal Article
Year 1993 Publication History and Philosophy of the Life Sciences Abbreviated Journal Hist Philos Life Sci
Volume 15 Issue 1 Pages 23-32
Keywords Animals; Bird Diseases/epidemiology/*history/microbiology; Birds; Ecology; History, 20th Century; Horse Diseases/epidemiology/*history/microbiology; Horses; Humans; Influenza A virus/*isolation & purification; Influenza, Human/epidemiology/*history/microbiology/*veterinary; Swine; Swine Diseases/epidemiology/*history/microbiology; Zoonoses/history
Abstract For 20 years after the influenza A virus was discovered in the early 1930s, it was believed to be almost exclusively a human virus. But in the 1950s closely related viruses were discovered in diseases of horses, pigs and birds. Subsequently influenza A viruses were found to occur frequently in many species of birds, particularly ducks, usually without causing disease. Researchers showed that human and animal strains can hybridise thus producing new strains. Such hybrids may be the cause of pandemics in man. Most pandemics have started in China or eastern Russia where many people are in intimate association with animals. This situation provides a breeding ground for new strains of influenza A virus.

Title Effect of indoor residual spraying of DDT and bendiocarb on the feeding patterns of Anopheles pseudopunctipennis in Mexico Type Journal Article
Year 1990 Publication Journal of the American Mosquito Control Association Abbreviated Journal J Am Mosq Control Assoc
Volume 6 Issue 4 Pages 635-640
Keywords Animals; Anopheles/*physiology; *Carbamates; Cattle; *Ddt; Ecology; Enzyme-Linked Immunosorbent Assay; Feeding Behavior/*drug effects; Horses; Humans; Insect Vectors; Insecticide Resistance; *Insecticides; Mexico; *Phenylcarbamates; Seasons
Abstract Intense and persistent use of DDT for malaria control has increased resistance and induced exophilic behavior of Anopheles pseudopunctipennis. An evaluation of bendiocarb and DDT to control this species in Sinaloa, Mexico, showed that, in spite of DDT-resistance, both insecticides produced similar effects. Feeding patterns were analyzed to explain these results. Resting mosquitoes were collected over the dry and wet seasons. Anophelines were tested in an ELISA to determine the source of the meals. The human blood index (HBI) ranged from 3.3 to 6.8% in DDT- and from 12.7 to 26.9% in bendiocarb-sprayed houses. Irritability and repellency in DDT-sprayed houses could explain the reduced HBI. In contrast, bendiocarb produced higher mortality. These effects could have affected different components of the vectorial capacity and similarly reduced malaria.

Title Ecology of a semi-isolated population of adult Anopheles freeborni: abundance, trophic status, parity, survivorship, gonotrophic cycle length, and host selection Type Journal Article
Year 1989 Publication The American Journal of Tropical Medicine and Hygiene Abbreviated Journal Am J Trop Med Hyg
Volume 41 Issue 2 Pages 169-176
Keywords Aging/physiology; Animals; Anopheles/*physiology; Breeding; California; Cattle/parasitology; Dogs/parasitology; Ecology; Feeding Behavior/physiology; Female; Horses/parasitology; Host-Parasite Relations; Male; Parity; Population Density; Rabbits/parasitology
Abstract A population of adult Anopheles freeborni near Sheridan, CA was sampled daily during 13 August-7 September 1984. Data on abundance, trophic status, and gonotrophic age were recorded. Abundance and gonotrophic age data were analyzed to estimate daily survivorship and gonotrophic cycle length. Daily survivorship for unfed mosquitoes was estimated to be 0.72 with a gonotrophic cycle of 6 days duration. Daily survivorship for bloodfed mosquitoes was estimated to be 0.74 with a gonotrophic cycle of 4 days. The 2 day difference in gonotrophic cycles between unfed and bloodfed mosquitoes was the result of the period required for maturation and mating of teneral females. In 1986, an incage release of field-collected females estimated survivorship at 0.75 per day. Precipitin tests of 1,338 blood-engorged mosquito abdomens indicated that bovids, horses, rabbits, and canids comprised 92% of bloodmeals; no bloodmeals of human origin were detected.

Title Physiology of Sporolactobacillus strains isolated from different habitats and the indication of in vitro antagonism against Bacillus species Type Journal Article
Year 1988 Publication International Journal of Food Microbiology Abbreviated Journal Int J Food Microbiol
Volume 7 Issue 2 Pages 161-168
Keywords Animals; Bacillaceae/isolation & purification/*physiology; Bacillus/*physiology; Cattle; *Ecology; Feces/*microbiology; Food Microbiology; Horses; Sewage; Sheep; Water Microbiology
Abstract In an ecological study only low numbers of Sporolactobacillus were found in habitats such as the faeces of herbivores, the rumen of cattle and the final waste water of an abattoir. Their presence in the final waste water of an abattoir indicates their possible association with food, and, more specifically, with meat. Differences were found in some physiological characteristics. One isolate (L2404) differed from the authentic Sporolactobacillus ATCC 15538 by its inability to ferment inulin, its growth in presence of 6.5% NaCl and in 0.2% tellurite, by the isomer(s) of lactic acid produced and the mol% G + G in the DNA. One Sporolactobacillus isolate (L2407) showed antagonism against Bacillus cereus, Bacillus cereus var, mycoides, Bacillus megaterium and Bacillus subtilis.

Title Strongylid parasites of horses: experimental ecology of the free-living stages on the Canadian prairie Type Journal Article
Year 1986 Publication American Journal of Veterinary Research Abbreviated Journal Am J Vet Res
Volume 47 Issue 8 Pages 1686-1693
Keywords Animals; Canada; Ecology; Feces; Female; Horse Diseases/*epidemiology/parasitology; Horses; Larva; Ovum/cytology; Seasons; Strongyloides/isolation & purification; Strongyloidiasis/epidemiology/*veterinary
Abstract Each month for a 1-year period (October through September), equine fecal masses containing eggs of strongylid nematodes were placed outdoors on small grass plots in Saskatchewan, Canada. Thereafter, feces and grass from the plots were sampled after intervals of 1 week or longer, and the strongylid eggs and larvae recovered were counted. These observations were made over a 2-year period. Development of eggs to infective larvae occurred in all experiments, except those established in October, December, and January. Infective larvae from experiments set up in April through September survived that winter. During the summer, there was a gradual build up of infective larvae in the fecal masses, which reached a peak in August and September and then decreased into the winter. These results are discussed in the context of the control of strongylid parasites of horses on the Canadian prairie and in other areas of the world with a similar climate and similar horse management practices.
