Promiscuous Mating In Feral Pigs (Sus Scrofa) From Texas, Usa, Johanna Delgado-Acevedo, Angeline Zamorano, Randy W. Deyoung, Tyler A. Campbell, David G. Hewitt, David B. Long

USDA Wildlife Services: Staff Publications

Context. Feral pigs represent a significant threat to agriculture and ecosystems and are disease reservoirs for pathogens affecting humans, livestock and other wildlife. Information on the behavioural ecology of feral pigs might increase the efficiency and effectiveness of management strategies.

Aims. We assessed the frequency of promiscuous mating in relation to oestrous synchrony in feral pigs from southern Texas, USA, an agroecosystem with a widespread and well established population of feral pigs. An association between multiple paternity of single litters and synchrony of oestrous may indicate alternative mating strategies, such as mateguarding.

Methods. We collected gravid sows at …

Chlorophacinone Baiting For Belding’S Ground Squirrels, Craig A. Ramey, George H. Matschke, Richard M. Engeman

USDA Wildlife Services: Staff Publications

The efficacy of using 0.01% chlorophacinone on steam-rolled oat (SRO) groats applied in CA alfalfa by spot-baiting/hand baiting around burrow entrances (~11.5 g) to control free-ranging Belding's ground squirrels (Spermophilus beldingi) were compared in 6 randomly assigned square treatment units (TUs). Four TUs were given the rodenticide and 2 treated with placebo bait. Each TU was a 0.4 ha square surrounded by a similarly treated 5.5 ha square buffer zone. Baits were applied on May 13 and re-applied, on May 20 and May 22, after 7 days of un-forecasted cool wet weather greatly reduced their above ground activity. Pesticide (EPA …

Enterobius Vermicularis: Ancient Dna From North And South American Human Coprolites, Alena M. Iñiguez, Karl J. Reinhard, Adauto Araújo, Luiz F. Ferreira, Ana Carolina P. Vicente

School of Natural Resources: Faculty Publications

A molecular paleoparasitological diagnostic approach was developed for Enterobius vermicularis. Ancient DNA was extracted from 27 coprolites from archaeological sites in Chile and USA. Enzymatic amplification of human mtDNA sequences confirmed the human origin. We designed primers specific to the E. vermicularis 5S ribosomal RNA spacer region and they allowed reproducible polymerase chain reaction identification of ancient material. We suggested that the paleoparasitological microscopic identification could accompany molecular diagnosis, which also opens the possibility of sequence analysis to understand parasite-host evolution.

Escherichia Coli O157:H7 In Free-Ranging Deer In Nebraska, David G. Renter, Jan M. Sargeant, Scott E. Hygnstrom, Jeff D. Hoffmann, Jerry R. Gillespie

School of Natural Resources: Faculty Publications

In order to determine the prevalence and distribution of the human pathogen, Escherichia coli O157:H7, in free-ranging deer, hunters were asked to collect and submit fecal samples from deer harvested during a regular firearm season (14–22 November 1998). Prior to the season, 47% of the hunters with permits in the southeastern Nebraska (USA) study area indicated a willingness to participate in the study. Approximately 25% of successful hunters in the area submitted deer fecal samples. Escherichia coli O157:H7 was cultured from four (0.25%) of 1,608 total samples submitted. All of the fecal samples that were properly identified (1,426) and all …

El Papel De Las Mujeres En La Conservación De Los Bosques Del Nepal, Augusta Molnar

Poverty, Gender, and Youth

Este número de SEEDS pone de relieve las formas en que se ha hecho participar a las mujeres en un programa gubernamental de conservación y restauración de bosques en Nepal. Como en muchos proyectos de gran escala e impacto generalizado, las mujeres no tenían un papel específico en el diseño original del proyecto. Pero una vez que comenzaron las actividades, tanto el personal nepales como sus colegas extranjeros tuvieron que reconocer que para que la estrategía participative pudiera funcionar, era esencial contar con las mujeres. De ahí que durante los primeros cinco anos del proyecto (1980–85) se probaron varias maneras …

La Conservation Des Forêts Au Népal: Encourager La Participation Des Femmes, Augusta Molnar

Poverty, Gender, and Youth

Ce numéro de SEEDS porte sur les moyens mis en oeuvre pour faire participer les femmes à un programme gouvernemental visant à preserver et à restituer la forêt au Népal. Comme il arrive fréquemment lors de la mise en place de projets aussi vastes ayant une portée generale, les femmes n'étaient pas un centre d'intérêt spécifique au moment de la conception du projet. Cependant, lorsque les activités ont demarré, les responsables népalais du projet et leurs collègues de l'étranger se sont tres vite rendus compte que le succès du programme dépendait de la participation directe des femmes aux activités du …

Forest Conservation In Nepal: Encouraging Women's Participation, Augusta Molnar

Poverty, Gender, and Youth

This issue of SEEDS focuses on ways in which women have been involved in a government forest conservation and restoration program in Nepal. As is common with many large-scale projects with a general impact, women were not a direct focus of the project's original design. As activities got underway, however, both the Nepali staff and their expatriate colleagues quickly realized that the direct involvement of women was crucial to the success of the project's participatory strategy. Over the initial five years, 1980 to 1985, a number of approaches to addressing women's needs and generating their active participation were tried. The …
