Impacts of elk management and riparian condition on songbirds in Rocky Mountain National Park
… elaphus). In 2008, RMNP began installing elk exclosures to protect and restore willow communities and the diverse taxa that depend on riparian ecosystems from heavy browsing. Using point counts, I evaluated the effect of elk exclosures and riparian shrub condition on songbird density and …

THE RELATIONSHIP BETWEEN WOODLAND CARIBOU, SOIL CARBON CYCLING AND SOIL FERTILITY ON THE SLATE ISLANDS ARCHIPELAGO IN ONTARIO, CANADA
… and snowshoe hare (<em>Lepus americanus</em>) exclosures on the islands in 2006, and have routinely monitored the vegetation to study the effects of limiting herbivory.</p> <p>This study explores the implications of limiting herbivory on soil fertility, carbon and nitrogen stocks, and …

Indirect effects between deer, mice, and the gypsy moth in a forest community
… on pupae inside, and outside, of long-term deer exclosures. Overall, I did not find evidence for indirect effects of deer on the gypsy moth. There was little effect of the exclosures on mouse abundance, predation rates, and habitat measures. High mouse abundances, which likely resulted from a …

Piping plover breeding biology and reproductive success on Assateague Island
… Recent experiments have indicated that predator exclosures constructed around individual nests can be used to reduce nest predation. These exclosures should be tested on Assateague. Future research efforts should focus on the role of foraging habitat in breeding site selection and the …

Predation/disturbance effects of greater flamingos (Phoenicopterus ruber) on the benthic communities of two Southern African lagoons
… approximately three times inside subtidal exclosures, and one and a half times intertidally, but diversity indices were similar between treatments. There was some evidence that amensalistic interactions developed between macrofauna within exclosures. Intertidally at Walvis Bay rneiofauna …

Evaluation of Barriers to Black-Tailed Prairie Dog (Cynomys ludovicianus) Colony Expansion, Bad River Ranches, South Dakota
… with chicken wire, American bison (Bison bison) exclosures, and straw bales. Barriers were 100 meters (328 ft) in length and located within 1 hectare monitoring plots (2.47 ac). Grazing and mechanical mowing were allowed on both sides of barriers. A prairie dog free zone was established on …

The Effects of Mammalian Herbivores on Successional Grasslands in Central Illinois
… forbs. Grasses palatable to voles increased in exclosures during mid- and late succession. Rodent exclusion also significantly increased abundance of the legume Medicago sativa, which had highly palatable shoots and seeds. Cirsium arvense, a palatable forb, increased substantially with the …

Diversity Relationships in Native, Warm-Season Plant Communities used for Agriculture
… biomass in both grazed areas and biomass crop exclosures. Analysis of forage nutritive value did not show many differences among mixtures, although the monoculture tended to have higher crude protein and lower fiber concentrations than the polycultures. Management method affected community …

Aiding conservation of the federally threatened Scutellaria montana (Lamiaceae, large-flowered skullcap) through abundance monitoring and transplantation studies
… best suited for transplantation when herbivory exclosures are absent. Controlling herbivory to maximize transplantation success is recommended.

Red fox ecology and interactions with piping plovers on Fire Island, New York
… although fox penetration of and digging at exclosures was an issue in 2015 at Smith Point County Park. Items from Orders Rodentia (rodents, 43% of scats), Coleoptera (beetles, 38%), and Decapoda (crabs and other crustaceans, 29%) were most frequently found in 293 red fox scats examined. …

Wildlife Decomposition in West Central Montana: A Preliminary Study Conducted to Provide Field Investigation Material and Training for Wildlife Officers
… total of 15 carcasses were placed in electrified exclosures during various times of the year which provided seasonal variation and include: a pair of gray wolves (8 total) placed on the same day for each of the four seasons; a black bear placed early fall, and another middle fall; three mountain …

Piping plover breeding biology, foraging ecology and behavior on Assateague Island National Seashore, Maryland
… by red foxes (Vulpes vulpes) was high. Predator exclosures constructed around individual nests did not increase nest survival. Chick survival was higher in bay beach and island interior brood-rearing habitats than on the ocean beach. Our evidence supports the hypothesis that the availability of …

Piping plover population dynamics and effects of beach management practices on piping plovers at West Hampton Dunes and Westhampton Beach, New York
… success and chick survival (R2 = 0.79). Predator exclosures at nests reduced nest loss (WHD = 34% exclosed nests lost vs. 43% of unexclosed nests lost, though in one year, one or more foxes learned to exploit plovers in exclosures (22% of all exclosed nests were predated by foxes in 1995). This …

Demography, Nest Site Selection, and Physiological and Behavioral Responses to Overflights and other Human Activities, of Wilson's Plover (Charadrius wilsonia) at Cape Lookout National Seashore, North Carolina

Management and Livestock Performance of Alfalfa-Tall Fescue Mixed Stands
… Management treatments conducted within wire exclosures included defoliation height, rest period, exclosure movement, and month and were evaluated using detailed botanical composition and persistence measurements. Defoliation height, rest period, and month all affected alfalfa-tall fescue …
