Burmese python (Python bivittatus) is an invasive snake that has significantly affected ecosystems in southern Florida, United States. Aside from direct predation and competition, invasive species can also introduce nonnative pathogens that can adversely affect native species. The subfamily Serpentovirinae (order Nidovirales) is composed of positive-sense RNA viruses primarily found in reptiles. Some serpentoviruses, such as shingleback nidovirus, are associated with mortalities in wild populations, while others, including ball python nidovirus and green tree python nidovirus can be a major cause of disease and mortality in captive animals. To determine if serpentoviruses were present in invasive Burmese …


A Review Of The Impacts Of Invasive Wild Pigs On Native Vertebrates, Matthew T. Mcdonough, Stephen S. Ditchkoff, Mark D. Smith, Kurt C. Vercauteren Feb 2022

A Review Of The Impacts Of Invasive Wild Pigs On Native Vertebrates, Matthew T. Mcdonough, Stephen S. Ditchkoff, Mark D. Smith, Kurt C. Vercauteren

The wild pig (Sus scrofa) is a successful invasive species that has become well established outside of its native range in Eurasia. The invasive wild pig is the result of released or escaped domesticated livestock becoming feral, or Eurasian boar introduced for hunting purposes. The global spread of wild pigs has recently been exacerbated in some areas, such as the USA, by anthropogenically assisted dispersal. Once established in novel ecosystems, wild pigs have the potential to have significant negative impacts on the ecosystem, and the scientific literature is replete with examples. It is generally accepted that wild pigs …


Environmental Effects On Biomass Allocation And Small Plot Evaluations Of Aquatic Pesticides For Control Of Nitellopsis Obtusa (Starry Stonewort) Collected From Lake Koronis In Stearns County, Minnesota, Patrick J. Carver Jan 2022

Environmental Effects On Biomass Allocation And Small Plot Evaluations Of Aquatic Pesticides For Control Of Nitellopsis Obtusa (Starry Stonewort) Collected From Lake Koronis In Stearns County, Minnesota, Patrick J. Carver

All Graduate Theses, Dissertations, and Other Capstone Projects

Phenology is the study of critical life stages in plants in relation to shifts in environmental factors during seasonal changes. Starry stonewort is a green macro alga in the family Characeae native to Eurasia. Much of the Midwestern United States has been invaded by this species. Starry stonewort has been seen to have late season growth patterns in its invaded range. This study found that this growth pattern was dependent upon water temperature and light transmittance both of which affect biomass production and senescence. It was hypothesized that peak biomass would occur in the late summer (August), however we observed …


A Review Of The Alien Fishes Of Turkish Inland Waters, Erdoğan Çi̇çek, Soheil Eagderi, Sevi̇l Sungur Jan 2022

A Review Of The Alien Fishes Of Turkish Inland Waters, Erdoğan Çi̇çek, Soheil Eagderi, Sevi̇l Sungur

Turkish Journal of Zoology

Aquaculture, recreational fishing, restocking, biological control, and the ornamental fish trade have increased the number of nonnative fish in Turkish inland waters. This work reviews the history, current state, and tendencies of fish introductions into Turkish freshwaters. To date, it is known that a total of 34 exotic species (except two marine and three misidentified species) have been introduced deliberately or accidentally into Turkish inland waters, of which, only 19 species have been established in wild ecosystems. A total of five acclimatized species, viz. Coregonus lavaretus, C. macrophthalmus, Salmo salar, Salvelinus alpinus, and S. fontinalis and four species, viz. Hypophthalmichthys …
