Earthworm, Microbial Biomass, And Leaf Litter Decay Responses After Invasive Honeysuckle Shrub Removal From Urban Woodlands., Robert Preston Pipal
Earthworm, Microbial Biomass, And Leaf Litter Decay Responses After Invasive Honeysuckle Shrub Removal From Urban Woodlands., Robert Preston Pipal
Electronic Theses and Dissertations
Invasive species are one of the leading causes of biodiversity loss and their presence can significantly impact the structure and function of native ecosystems. In this dissertation, the impacts of the invasive honeysuckle shrub, Lonicera maackii, on exotic earthworm populations, leaf litter decay responses, and inorganic and organic nutrient pools in an urban woodland park are assessed. Chapter 1 provides a brief review of honeysuckle's effects on forest ecosystems. Chapter 2 describes honeysuckle’s effects on exotic earthworm populations and the seasonal importance of macroinvertebrates to leaf litter decomposition in urban woodlands. This study revealed that L. maackii promoted higher exotic …
Determinants Of Bite Force In Four Species Of Sharks From The Gulf Of Mexico With An Emphasis On The Atlantic Sharpnose Shark, Rhizoprionodon Terraenovae, Kyle Walter Rice
Determinants Of Bite Force In Four Species Of Sharks From The Gulf Of Mexico With An Emphasis On The Atlantic Sharpnose Shark, Rhizoprionodon Terraenovae, Kyle Walter Rice
Electronic Theses and Dissertations
Bite force can provide valuable information regarding the physiological ecology of an organism. However, there have been few studies wherein bite force in sharks has been considered. Herein I report on a study of the bite force of four species of sharks with particular emphasis on that of the atlantic sharpnose shark, rhizoprionodon terraenovae. Among the four species examined, blacktip shark, carcharhinus limbatus bite force was significantly higher than that of sharpnose, rhizoprionodon terraenovae. There was no significant difference between the bite force of those species compared with the same for finetooth shark, c. Isodon and spinner shark, c. Brevipinna. …
