Physiological And Behavioural Responses To Noxious Stimuli In The Atlantic Cod (Gadus Morhua), Jared R. Eckroth, Øyvind Aas-Hansen, Lynne U. Sneddon, Helena Bichão, Kjell B. Døving

Animal Sentience, Intelligence, and Behavior

In the present study, our aim was to compare physiological and behavioural responses to different noxious stimuli to those of a standardized innocuous stimulus, to possibly identify aversive responses indicative of injury detection in a commercially important marine teleost fish, the Atlantic cod. Individual fish were administered with a noxious stimulus to the lip under short-term general anaesthesia (MS-222). The noxious treatments included injection of 0.1% or 2% acetic acid, 0.005% or 0.1% capsaicin, or piercing the lip with a commercial fishing hook. Counts of opercular beat rate (OBR) at 10, 30, 60, 90 and 120 min ...

Reproductive Timing Of Erimystax Insignis (Blotched Chub) In The Flint River Of North Alabama, Bruce Stallsmith, Josh Mann, Candice Allen

Southeastern Fishes Council Proceedings

Important details of the reproductive ecology of many freshwater fishes of the species-rich southeastern United States are still poorly known. One such species is Erimystax insignis (Blotched Chub), whose range includes the Tennessee River drainage in northern Alabama, USA. To determine timing and patterns of reproductive effort, collections were made monthly of as many as 30 individuals from August 2011 through July 2012 from a 14 km stretch of the Flint River in Madison County, Alabama. Female and male gonadosomatic index (GSI) and ovarian development data indicate that reproductive activity for the species peaks from March through May. Ripe and ...

Assessing Feeding Preferences And Spatial Patterns Of Lagodon Rhomboides Linnaeus, Alexandria v. Lamle 2015 Kennesaw State University

Assessing Feeding Preferences And Spatial Patterns Of Lagodon Rhomboides Linnaeus, Alexandria V. Lamle

Master of Science in Integrative Biology Theses

Mesograzers have the ability to greatly mitigate the effects of eutrophication in seagrass systems. In this study we look at pinfish (Lagodon rhomboides Linnaeus) as a potential epiphytic grazer and assess feeding preferences during a transitional stage in the ontogenetic diet shift exhibited by these fish. Since pinfish are abundant in seagrass meadows in the northern Gulf of Mexico, their dietary preferences have the potential to greatly impact seagrasses in this system. Twenty-four hour feeding trials were conducted to determine pinfish preference between seagrass (Thalassia testudinum) and algal epiphytes. St. Joseph Bay, FL was also surveyed to determine areas within ...

Soil Organic Carbon And Nitrogen Storage In Two Southern California Salt Marshes: The Role Of Pre-Restoration Vegetation, Jason Keller, Tyler Anthony, Dustin Clark, Kristin Gabriel, Dewmini Gamalath, Ryan Kabala, Julie King, Ladyssara Medina, Monica Nguyen 2015 Chapman University

Soil Organic Carbon And Nitrogen Storage In Two Southern California Salt Marshes: The Role Of Pre-Restoration Vegetation, Jason Keller, Tyler Anthony, Dustin Clark, Kristin Gabriel, Dewmini Gamalath, Ryan Kabala, Julie King, Ladyssara Medina, Monica Nguyen

Bulletin of the Southern California Academy of Sciences

Soil organic carbon and nitrogen storage represent important ecosystem services provided by salt marshes. To test the importance of vegetation on soil properties, we measured organic carbon, total nitrogen, and belowground biomass in two southern California salt marshes. In both marshes, cores were collected from areas which differed in dominant vegetation cover prior to the restoration of tidal influence. There were no differences in organic carbon or total nitrogen density between vegetation classes at either site; however, a relationship between belowground biomass and soil organic carbon suggests that vegetation may influence soil properties.

Carbon Storage Potential Of Windbreaks On Agricultural Lands Of The Continental United States, William Ballesteros Possu 2015 William University of Nebraska-Lincoln

Carbon Storage Potential Of Windbreaks On Agricultural Lands Of The Continental United States, William Ballesteros Possu

Dissertations & Theses in Natural Resources

Agricultural production systems face major challenges under climate change scenarios in terms of expected negative impacts on productivity and persistence of the crops. Greenhouse gases from agriculture continue to rise although not as fast as from other fossil fuel-based human activities. Windbreaks perform several ecosystems functions that improve the local and regional capacity of crop systems to increase yields and offer environmental services by minimizing the negative effects of extreme weather events. Windbreaks also represent an important means of mitigating greenhouse gas emissions. This is predominantly accomplished by the windbreak trees storing carbon (C) in their above and belowground woody ...

Seasonal Dynamics And Micro-Climatic Preference Of Two Alpine Endemic Hypogean Beetles, Stefano Mammola, Elena Piano, Pier Mauro Giachino, Marco Isaia 2015 University of Turin, Torino

Seasonal Dynamics And Micro-Climatic Preference Of Two Alpine Endemic Hypogean Beetles, Stefano Mammola, Elena Piano, Pier Mauro Giachino, Marco Isaia

International Journal of Speleology

Hypogean beetles generally live in stable environments, characterized by constant temperature and high relative humidity. Changes in the underground microclimatic conditions generally induce local migrations of the beetles through the hypogean environment in search of suitable microhabitats. We studied the seasonal dynamics and the micro-climatic preference of two Alpine endemic hypogean beetles - Sphodropsis ghilianii (Coleoptera, Carabidae) and Dellabeffaella roccae (Coleoptera, Cholevidae) - in the hypogean complex of Pugnetto (Graian Alps, Italy). We surveyed the two species for one year, using baited pitfall traps and measuring temperature and humidity along the two main caves. We used logistic regression mixed models (GLMMs) to ...


Matching Watershed And Otolith Chemistry To Establish Natal Origin Of An Endangered Desert Lake Sucker, Deanna Strohm 2015 Utah State University

Matching Watershed And Otolith Chemistry To Establish Natal Origin Of An Endangered Desert Lake Sucker, Deanna Strohm

All Graduate Theses and Dissertations

Like many native endemic desert freshwater fish species, the June Sucker (Chasmistes liorus) is currently listed as endangered. Managers have increasingly turned to habitat restoration as a key component to recovery plans. For endangered species, one of the primary outcomes of habitat restoration is that it should result in successful reproduction and recruitment of individuals into the adult population. Confirmation of natural recruitment as a function of habitat restoration can only be achieved by establishing natal origins.

Recent research has proven the validity of otolith microchemistry, a technique that analyzes small quantities of elements, to trace potamodromous fish to their ...

Changing Climates, Fading Cultures: A Study Of Place Annihilation As A Result Of Climate Change, Brooks A. Bolsinger 2015 Seattle Pacific University

Changing Climates, Fading Cultures: A Study Of Place Annihilation As A Result Of Climate Change, Brooks A. Bolsinger

Honors Projects

Abstract

Research has established the phenomenon of cultural annihilation: the notion that the members of cultures can perceive a sense of loss when the geography upon which their culture is built undergoes a dramatic destructive change. This review examines prevailing literature to uncover existing and expected ways that climate change will impact cultures, specifically damaging the shared history that is infused into the geographic traits that make up a culture’s homeland. It examines three case studies - Native American tribes in Alaska, the island nation of the Maldives, and the country of the Netherlands – to highlight vulnerabilities that these three ...


Tolerance Of The Invasive New Zealand Mud Snail To Various Decontamination Procedures, Christopher N. Acy 2015 Lawrence University

Tolerance Of The Invasive New Zealand Mud Snail To Various Decontamination Procedures, Christopher N. Acy

Lawrence University Honors Projects

In an attempt to stop the spread of invasive species, state governments have established decontamination procedures for use on contaminated equipment. However, different species can tolerate various procedures depending on their morphology and physiology. The New Zealand mud snail (Potamopyrgus antipodarum) is invasive to the United States and may alter the food web of streams due to the snail’s high reproductive ability, causing potential problems for native trout populations and local economies. We collected mud snails from the recently invaded Black Earth Creek, WI and tested their tolerance to decontamination protocols being considered by the Wisconsin Department of Natural ...


Diel Vertical Migration Of An Invasive Calanoid Copepod, Eurytemora Affinis, In Little Sturgeon Bay, Wisconsin, Alexandra N. Poli 2015 Lawrence University

Diel Vertical Migration Of An Invasive Calanoid Copepod, Eurytemora Affinis, In Little Sturgeon Bay, Wisconsin, Alexandra N. Poli

Lawrence University Honors Projects

Eurytemora affinis, a calanoid copepod, is known to be a versatile, prolific invader of freshwater ecosystems across the globe. It has recently been documented in the Laurentian Great Lakes, including in Little Sturgeon Bay, an embayment of Lake Michigan. One survival mechanism that could make E. affinis a successful invader is diel vertical migration (DVM), a behavior in which animals move to different lakes depths at different times of day in order to avoid predation. Much is known about DVM of E. affinis, but primarily from studies in marine and brackish systems. Our goal was to investigate how E. affinis ...
