Predicting Combined Effects Of Land Use And Climate Change On River And Stream Salinity, John Olson Dec 2018

Predicting Combined Effects Of Land Use And Climate Change On River And Stream Salinity, John Olson

John Olson

Agricultural, industrial and urban development have all contributed to increased salinity in streams and rivers, but the likely effects of future development and climate change are unknown. I developed two empirical models
to estimate how these combined effects might affect salinity by the end of this century (measured as electrical conductivity, EC). The first model predicts natural background from static (e.g. geology and soils) and dynamic
(i.e. climate and vegetation) environmental factors and explained 78% of the variation in EC. I then compared the estimated background EC with current measurements at 2001 sites chosen probabilistically from all conterminous USA streams. …

Cephalopods Are Best Candidates For Invertebrate Consciousness, Jennifer A. Mather, Claudio Carere Jun 2018

Cephalopods Are Best Candidates For Invertebrate Consciousness, Jennifer A. Mather, Claudio Carere

Jennifer Mather, PhD

Insects might have been the first invertebrates to evolve sentience, but cephalopods were the first invertebrates to gain scientific recognition for it.

An Invertebrate Perspective On Pain, Jennifer A. Mather Jun 2018

An Invertebrate Perspective On Pain, Jennifer A. Mather

Jennifer Mather, PhD

Although Key (2016) argues that mammals feel pain and fish do not, from an invertebrate perspective, it is obvious that the pain experience is shared by animals from a number of different animal groups.

Lethal And Sublethal Effects Of Novel Terrestrial Subsidies From An Invasive Shrub (Lonicera Maackii) On Stream Macroinvertebrates, Ryan W. Mcewan, Kevin W. Custer, Eric B. Borth, Sean D. Mahoney Jan 2018

Lethal And Sublethal Effects Of Novel Terrestrial Subsidies From An Invasive Shrub (Lonicera Maackii) On Stream Macroinvertebrates, Ryan W. Mcewan, Kevin W. Custer, Eric B. Borth, Sean D. Mahoney

Ryan McEwan

The biology of headwater streams is intimately linked to that of the surrounding terrestrial environment through organic matter subsidies. Lonicera maackii, an invasive shrub that is becoming abundant in headwater stream riparian areas, deposits substantial quantities of organic matter into the aquatic system. This organic material has allelopathic effects on terrestrial plants and insects, and a growing body of work suggests strong connections between L. maackii invasion and aquatic biota. Lonicera maackii deposits fruit and flowers in quantities and timings that are unique, and we tested the hypothesis that these subsidies would negatively affect survival and growth of laboratory-cultured …
