Range Expansion Of Tick Disease Vectors In North America: Implications For Spread Of Tick-Borne Disease, Daniel E. Sonenshine Jan 2018

Range Expansion Of Tick Disease Vectors In North America: Implications For Spread Of Tick-Borne Disease, Daniel E. Sonenshine

Biological Sciences Faculty Publications

Ticks are the major vectors of most disease-causing agents to humans, companion animals and wildlife. Moreover, ticks transmit a greater variety of pathogenic agents than any other blood-feeding arthropod. Ticks have been expanding their geographic ranges in recent decades largely due to climate change. Furthermore, tick populations in many areas of their past and even newly established localities have increased in abundance. These dynamic changes present new and increasing severe public health threats to humans, livestock and companion animals in areas where they were previously unknown or were considered to be of minor importance. Here in this review, the geographic …

Assessment Of The Carbonate Chemistry Seasonal Cycles In The Southern Ocean From Persistent Observational Platforms, N. L. Williams, L. W. Juranek, R. A. Feely, J. L. Russell, K. S. Johnson, B. Hales Jan 2018

Assessment Of The Carbonate Chemistry Seasonal Cycles In The Southern Ocean From Persistent Observational Platforms, N. L. Williams, L. W. Juranek, R. A. Feely, J. L. Russell, K. S. Johnson, B. Hales

Marine Science Faculty Publications

Observations from Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) biogeochemical profiling Argo floats are used to characterize the climatological seasonal cycles and drivers of dissolved inorganic carbon, total alkalinity, pH, the partial pressure of carbon dioxide (CO2), and the saturation state of aragonite at the surface and at 200 m across five Southern Ocean frontal regimes, including under sea ice. The Southern Ocean ranges from a temperature-dominated system in the northernmost Subtropical Zone to a biologically dominated system in the most poleward Seasonal Sea Ice Zone. In all zones, the ingassing or outgassing of CO2 …

Rapid Coastal Forest Decline In Florida's Big Bend, Matthew J. Mccarthy, Benjamin Dimmitt, Frank E. Muller-Karger Jan 2018

Rapid Coastal Forest Decline In Florida's Big Bend, Matthew J. Mccarthy, Benjamin Dimmitt, Frank E. Muller-Karger

Marine Science Faculty Publications

Coastal ecosystems throughout the world are increasingly vulnerable to degradation as a result of accelerating sea-level rise and saltwater intrusion, more frequent and powerful extreme weather events, and anthropogenic impacts. Hardwood swamp forests in the Big Bend region of Florida’s Gulf of Mexico coast (USA) are largely devoid of the latter, but have degraded rapidly since the turn of the 21st Century. Photographs of the forest, collected on the ground since 2009, were used to guide an analysis of a 60 km2 study area using satellite images. The images confirm that the coastal forest area declined 0.60% from 1982 …
