MANTER: Journal of Parasite Biodiversity
Anthropocommensal rodents live in close proximity to humans in many habitats around the world. They are a threat to public health because of the pathogens they carry. Recent studies in Mérida, Yucatán, México, have shown that commensal rodents harbor potential zoonotic pathogens such as bacteria, helminths, and viruses. In this study, we describe reproductive and demographic parameters of house mice and black rats present in households from Mérida, Yucatán, México, a municipality located in a tropical region in southern México. Rodents were trapped in 142 households within the municipality of Mérida from 2011 to 2014. A total of 832 rodents …
Elevational Variation In Body-Temperature Response To Immune Challenge In A Lizard, Francisco Javier Zamora-Camacho, Senda Reguera, Gregorio Moreno-Rueda
Elevational Variation In Body-Temperature Response To Immune Challenge In A Lizard, Francisco Javier Zamora-Camacho, Senda Reguera, Gregorio Moreno-Rueda

Immunocompetence benefits animal fitness by combating pathogens, but also entails some costs. One of its main components is fever, which in ectotherms involves two main types of costs: energy expenditure and predation risk. Whenever those costs of fever outweigh its benefits, ectotherms are expected not to develop fever, or even to show hypothermia, reducing costs of thermoregulation and diverting the energy saved to other components of the immune system. Environmental thermal quality, and therefore the thermoregulation cost/benefit balance, varies geographically. Hence, we hypothesize that, in alpine habitats, immune-challenged ectotherms should show no thermal response, given that (1) hypothermia would be …
Ecology Of Two Reintroduced Black Bear Populations In The Central Appalachians, Sean Mccarthy Murphy
Ecology Of Two Reintroduced Black Bear Populations In The Central Appalachians, Sean Mccarthy Murphy
Theses and Dissertations--Animal and Food Sciences
Reintroduced populations are vulnerable to demographic and environmental stochasticity, deleterious genetic effects, and reduced population fitness, all of which can increase extinction probability. Population viability is principle to determining the status of reintroduced populations and for guiding management decisions. To attempt to reestablish black bear (Ursus americanus) populations in the central Appalachians, two reintroductions using small founder groups occurred during the 1990s in the Big South Fork area along the Kentucky-Tennessee border (BSF) and in the Jefferson National Forest along the Kentucky-Virginia border (KVP). My objectives were to estimate demographic and genetic parameters, and to evaluate long-term viability …
Seasonal Habitat Selection Of The North American Porcupine (Erethizon Dorsatum) In A Coastal Dune Forest, Cara L. Appel
Seasonal Habitat Selection Of The North American Porcupine (Erethizon Dorsatum) In A Coastal Dune Forest, Cara L. Appel
Cal Poly Humboldt theses and projects
Wildlife-habitat relationship studies are important for understanding the factors that determine where species occur in space and time. Habitat selection by generalist species should be studied on fine spatial and temporal scales to avoid masking important differences between seasons, localities, or orders of selection. I conducted the first study of habitat use and general ecology of North American porcupines (Erethizon dorsatum) in a coastal dune environment. Specifically, I assessed changes in body mass, home range size, and habitat selection in relation to the potential for seasonal nutritional and survival bottlenecks as reported elsewhere. Although they are considered generalists, …
Faunistic And Zoogeographical Composition And Preliminary Evaluations Of Some Ecological Features Of The Subfamily Staphylininae (Coleoptera: Staphylinidae) Ofthe Central Anatolian Region Of Turkey, Senem Firat, Osman Sert
Faunistic And Zoogeographical Composition And Preliminary Evaluations Of Some Ecological Features Of The Subfamily Staphylininae (Coleoptera: Staphylinidae) Ofthe Central Anatolian Region Of Turkey, Senem Firat, Osman Sert
Turkish Journal of Zoology
The focus of this study is to provide the faunistic, ecological, and zoogeographical status of Staphylininae (Coleoptera: Staphylinidae) fauna of the Central Anatolian Region of Turkey. The study material comprises specimens collected from field studies between 2009 and 2012 and also specimens that were previously collected by other researchers. In total, 90 taxa of 26 genera belonging to 3 tribes of Staphylininae were recorded. Number of specimens, collection habitats and methods, months, and altitudes are given in a table and figures for collected species. Distributions of species in other regions of Turkey and zoogeographical regions are also given in the …
