Effects Of Varying Heat Indexes On Habitat Utilization And Behavior On Captive Red-Ruffed Lemurs (Varecia Rubra), Jeffrey Gammon
Effects Of Varying Heat Indexes On Habitat Utilization And Behavior On Captive Red-Ruffed Lemurs (Varecia Rubra), Jeffrey Gammon
The Pegasus Review: UCF Undergraduate Research Journal
The two captive red-ruffed lemurs (Varecia rubra) at the Central Florida Zoo experienced a more temperate climate and utilized a differing habitat than they would in their native range, Madagascar. Proper management of the species in captivity is crucial for its long-term survival as they are critically endangered. Over a four month period, heat index temperature, lemur behavior, and habitat utilization data were collected via an instantaneous scan sample. Variables were analyzed to characterize how variations in heat index alter habitat utilization and behavior of the captive lemurs. As the heat index increased, habitat use became more restricted …
Defense Trade-Offs In The Evolution Of The Fruits And Flowers Of Genus Cornus, Danielle R. De La Pascua
Defense Trade-Offs In The Evolution Of The Fruits And Flowers Of Genus Cornus, Danielle R. De La Pascua
Honors Undergraduate Theses
The optimal defense hypothesis predicts that the allocation of plant defenses across plant organs is proportional to the importance of a given organ to plant fitness. Despite this, much less work has been devoted to the study of reproductive defenses in plants relative to vegetative structures like leaves. This study examines the apparancy hypothesis and the resource availability hypothesis using a phylogenetic comparative approach within the genus Cornus . During the 2016 growing season, plants of 25 species of Cornus were tracked for flower and fruit phenology as well as sampled for floral and fruit tissue in a common garden …
Effects Of Mechanical Habitat Disturbance On The Diversity And Network Structure Of Plant-Bee Interaction Networks In Central Florida, Karlie Carman
Effects Of Mechanical Habitat Disturbance On The Diversity And Network Structure Of Plant-Bee Interaction Networks In Central Florida, Karlie Carman
Electronic Theses and Dissertations
Ecological interactions within a community shape the structure of ecosystems and influence ecosystem function. Plant-pollinator interactions exist as mutualistic exchange networks that may collapse as habitat loss occurs, thereby threatening the overall health of an ecosystem. Understanding the impacts of human-mediated habitat disturbance on ecological interactions is therefore crucial for conservation efforts. Archbold Biological Station (ABS) in Venus, Florida contains over 2000 hectares of protected Florida scrub habitat nested within a human-dominated environment that is threatened by anthropogenic habitat disturbance. In past studies, over 113 bee species and 157 associated host plants, many endemic to the Lake Wales Ridge, have …
Evaluation Of The Three-Dimensional Patterns And Ecological Impacts Of The Invasive Old World Climbing Fern (Lygodium Microphyllum), Alexis Maldonado
Evaluation Of The Three-Dimensional Patterns And Ecological Impacts Of The Invasive Old World Climbing Fern (Lygodium Microphyllum), Alexis Maldonado
Electronic Theses and Dissertations
Invasion by non-native species has had significant ecological and economic impacts on a global scale. In the state of Florida, Old World climbing fern (Lygodium microphyllum) is an invasive plant listed by FLEPPC as a category one invader with significant ecological impacts that threaten native plant diversity. This species relies on existing vegetative structures for support to climb into the forest canopy and forms dense mats that cover tree crowns. This subsequently affects the resources available to other species present. Quantifying the structural changes due to the presence of this species has proved logistically difficult, especially on a large spatial …
