Wild Pig Habitat Use, Substrate Disturbance, And Understory Vegetation At Congaree National Park, Scott Zengel
Wild Pig Habitat Use, Substrate Disturbance, And Understory Vegetation At Congaree National Park, Scott Zengel
All Dissertations
Substrate disturbance by wild pigs ( Sus scrofa L.), mainly wild pig rooting, was evaluated bi&ndashmonthly over three years in fixed 1,000 m2 plots at Congaree National Park, South Carolina, USA. The study compared hog substrate disturbance among four habitats: three mature wetland floodplain forest types (mixed bottomland hardwoods, cypress&ndashtupelo swamp, seepage floodplain forest), and successional upland pine flatwoods adjacent to the floodplain (including former pine plantation). New disturbance included fresh signs of hog substrate disturbance. Total disturbance included both new and older hog disturbance still visible on the landscape (equivalent to all disturbance that would be recorded under less …
Parent-Offspring Resource Allocation In Domestic Pigs, Anna Drake, David Fraser, Daniel M. Weary
Parent-Offspring Resource Allocation In Domestic Pigs, Anna Drake, David Fraser, Daniel M. Weary
Feeding Behavior Collection
Behavioural research on domestic pigs has included parent-offspring conflict, sibling competition, and the use of signals which influence resource allocation. In this paper, we review key sow-piglet behavioural studies and discuss their relevance to resource allocation theory. Sibling competition begins in the uterus and continues after birth, as piglets compete directly for access to the sow's teats. This competition is made more severe by a unique dentition, which newborn piglets use to lacerate the faces of siblings during teat disputes. Competition often leads to the death of some littermates, especially those of low birth weight. Piglets also compete indirectly for …
Mammalian Visitation To Candidate Feral Swine Attractants, Tyler A. Campbell, David B. Long
Mammalian Visitation To Candidate Feral Swine Attractants, Tyler A. Campbell, David B. Long
USDA Wildlife Services: Staff Publications
Few data exist regarding suitable feral swine (Sus scrofa) attractants in the United States. We compared species-specific visitation and contact rates of mammals to 11 candidate feral swine attractants at scent stations using motion-sensing digital photography to identify promising attractants. We found feral swine had greater visitation rates to apple and strawberry stations than to control stations. We recommend managers consider using strawberry attractants for feral swine-specific applications. If, however, a general feral swine attractant is needed, then apple, berry, or caramel attractants may perform well.
