Fire Induced Reproductive Mechanisms Of A Symphoricarpos (Caprifoliaceae) Shrub After Dormant Season Burning, John Derek Scasta, David M. Engle, Ryan N. Harr, Diane M. Debinski Dec 2014

Fire Induced Reproductive Mechanisms Of A Symphoricarpos (Caprifoliaceae) Shrub After Dormant Season Burning, John Derek Scasta, David M. Engle, Ryan N. Harr, Diane M. Debinski

Ecology, Evolution and Organismal Biology Publications

Background: Symphoricarpos, a genus of the Caprifoliaceae family, consists of about 15 species of clonal deciduous shrubs in North America and 1 species endemic to China. In North American tallgrass prairie, Symphoricarpos orbiculatus (buckbrush) is the dominant shrub often forming large colonies via sexual and asexual reproductive mechanisms. Symphoricarpos shrubs, in particular S. orbiculatus, use a unique sexual reproductive mechanism known as layering where vertical stems droop and the tips root upon contact with the soil. Because of conflicting societal values of S. orbiculatus for conservation and agriculture and the current attempt to restore historical fire regimes, there is a ...


Habitat Use Of The Key Largo Woodrat (Neotoma Floridana Smalli), Lauren J. Barth Nov 2014

Habitat Use Of The Key Largo Woodrat (Neotoma Floridana Smalli), Lauren J. Barth

FIU Electronic Theses and Dissertations

Key Largo woodrats are an endangered subspecies with an extremely limited habitat. This study sought to understand woodrat habitat preferences in order to guide management. Woodrats build stick nests from natural and artificial materials, so nest distribution and nest occupancy were used as indicators of preference. Distribution was determined by nest surveys, and remote cameras were used to assess occupancy. Forest structure, human disturbance, nest, and animal presence metrics were also collected. More nests were found along abandoned roads than along forest transects and more artificial nests were occupied than natural nests. These findings indicate that woodrats prefer areas with ...


Monteverde: Ecology And Conservation Of A Tropical Cloud Forest - 2014 Updated Chapters, Nalini M. Nadkarni, Nathaniel T. Wheelwright Jan 2014

Monteverde: Ecology And Conservation Of A Tropical Cloud Forest - 2014 Updated Chapters, Nalini M. Nadkarni, Nathaniel T. Wheelwright

Bowdoin Scholars' Bookshelf

The Monteverde Cloud Forest Reserve has captured the worldwide attention of biologists, conservationists, and ecologists and has been the setting for extensive investigation over the past 40 years. Roughly 40,000 ecotourists visit the Cloud Forest each year, and it is often considered the archetypal high-altitude rain forest. “Monteverde: Ecology and Conservation of a Tropical Cloud Forest”, edited by Nalini Nadkarni and Nathaniel T. Wheelwright (Oxford University Press, 2000 and Bowdoin’s Scholar’s Bookshelf. Book 1 ), features synthetic chapters and specific accounts written by more than 100 biologist and local residents, presenting in a single volume everything known in ...

Parasites are agents of disease in humans, livestock, crops, and wildlife and are powerful representations of the ecological and historical context of the diseases they cause. Recognizing a nexus of professional opportunities and global public need, we gathered at the Cedar Point Biological Station of the University of Nebraska in September 2012 to formulate a cooperative and broad platform for providing essential information about the evolution, ecology, and epidemiology of parasites across host groups, parasite groups, geographical regions, and ecosystem types. A general protocol, documentation–assessment–monitoring–action (DAMA), suggests an integrated proposal to build a proactive capacity to understand ...


Studies On The Ecology Of The Endangered Camaenid Land Snail Thersites Mitchellae (Cox, 1864), Jonathan Leslie Parkyn Jan 2014

Studies On The Ecology Of The Endangered Camaenid Land Snail Thersites Mitchellae (Cox, 1864), Jonathan Leslie Parkyn

Theses

Many Australian land snail species are assumed to have declined in distribution and abundance, but there are few quantitative data available to assess their conservation status. Thersites mitchellae (Cox, 1864) (Camaenidae) is listed as endangered (category ENC2a) on the IUCN 1997 Red List of Threatened Species. Population parameters such as abundance, probability of survival, and probability of site occupancy were estimated. The methods take detection probability into account and allow for the inclusion of sampling, habitat, and individual animal covariates. These models and techniques offer considerable scope for application to land snail conservation particularly for species at risk of extinction.
