Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Terrestrial animals must support their bodies against gravity, while aquatic animals are effectively weightless because of buoyant support from water. Given this evolutionary history of minimal gravitational loading of fishes in water, it has been hypothesized that weight-responsive musculoskeletal systems evolved during the tetrapod invasion of land and are thus absent in fishes. Amphibious fishes, however, experience increased effective weight when out of water – are these fishes responsive to gravitational loading? Contrary to the tetrapod-origin hypothesis, we found that terrestrial acclimation reversibly increased gill arch stiffness (∼60% increase) in the amphibious fish Kryptolebias marmoratus when loaded normally by gravity, …

What Would The Babel Fish Say?, Monica Gagliano Jan 2016

What Would The Babel Fish Say?, Monica Gagliano

Animal Sentience

Starting with its title, Key’s (2016) target article advocates the view that fish do not feel pain. The author describes the neuroanatomical, physiological and behavioural conditions involved in the experience of pain in humans and rodents and confidently applies analogical arguments as though they were established facts in support of the negative conclusion about the inability of fish to feel pain. The logical reasoning, unfortunately, becomes somewhat incoherent, with the arbitrary application of the designated human criteria for an analogical argument to one animal species (e.g., rodents) but not another (fish). Research findings are reported selectively, and questionable interpretations are …


A Missing Link In The Ionoregulatory Strategy Of Larval Sea Lamprey (Petromyzon Marinus) And African Lungfish (Protopterus Annectens): A Closer Look Into The Role Of The Non-Gastric H+/K+-Atpase, Justine E. Doherty Jan 2016

A Missing Link In The Ionoregulatory Strategy Of Larval Sea Lamprey (Petromyzon Marinus) And African Lungfish (Protopterus Annectens): A Closer Look Into The Role Of The Non-Gastric H+/K+-Atpase, Justine E. Doherty

Theses and Dissertations (Comprehensive)

Fishes living in freshwater need to actively compensate for the diffusive loss of ions and osmotic gain of water. The gill is the primary organ of ion regulation and contains an array of ion transport proteins to help maintain homeostasis. Two of the more well studied ion pumps are the Na+/K+-ATPase (NKA) and vacuolar type proton ATPase (V-ATPase). This thesis focuses on another ion pump known as the non-gastric H+/K+-ATPase (ngHKA). The ngHKA (gene: atp12a) has not been found in any of the teleost fishes, indicating loss from that lineage. In …

Effects Of Pre-Release Physical Stressors On Post-Release Success Of Hatchery-Reared Spotted Seatrout, Taylor Westbrook Guest May 2015

Effects Of Pre-Release Physical Stressors On Post-Release Success Of Hatchery-Reared Spotted Seatrout, Taylor Westbrook Guest

Master's Theses

Alteration of habitat associated with coastal development and increased demand for food and recreation can result in the depletion of fisheries resources such as the Spotted Seatrout (Cynoscion nebulosus), the Gulf of Mexico’s most popular recreational fish. Stock enhancement, or the release of cultured fish to supplement wild populations, is one potential tool for managing important fisheries resources. Although much effort has gone into marine stock enhancement, the effectiveness of stocking is not well established, and techniques for ensuring success have not been developed. Although the basic biology of the Spotted Seatrout is well known, comparatively little is known about …


Fauna Census Of Intertidal Cliffs, Mangapwani, Zanzibar, Emily Jankowski Apr 2015

Fauna Census Of Intertidal Cliffs, Mangapwani, Zanzibar, Emily Jankowski

Independent Study Project (ISP) Collection

Due to their extreme variations in condition over the course of a day, intertidal zones are challenging environments. Organisms that live there must be prepared to cope with both exposure and submersion, not to mention the temperature variations that accompany these conditions. The differing tolerances and adaptations of various organisms to these conditions generally cause patterns of vertical zonation to occur in the intertidal zone, especially when the shore is steep and rocky. Understanding the ecology of shore environments is important to future conservation and management efforts. This study was conducted on a beach in Mangapwani, Zanzibar at at 6˚ …

Fish Use Of Largely Unexplored Sub-Tidal Habitats In The Hinchinbrook Channel Estuary, Queensland, Alexandra Parisien Apr 2015

Fish Use Of Largely Unexplored Sub-Tidal Habitats In The Hinchinbrook Channel Estuary, Queensland, Alexandra Parisien

Independent Study Project (ISP) Collection

This study examines the use of sub-tidal open-bottom, rocky, and seagreass habitats by the Siganus genus (herbivores), Gerres genus (benthivores), and planktivores in the Hinchinbrook Channel Estuary in Queensland, Australia. The Hinchinbrook Channel Estuary, a tropical estuary cutting between Hinchinbrook Island and the Australian mainland, is surrounded primarily by mangroves. Its sub-tidal habitats are largely unexplored due to factors such as low visibility and the presence of estuarine crocodiles. In this study, I reviewed 699 underwater videos collected by James Cook University PhD candidate Michael Bradley in order to analyze feeding and movement behavior of pre-identified fish.

The results of …


Examining Predation As A Possible Means Of Controlling Crown-Of- Thorns Starfish (Acanthaster Planci) Outbreaks On Reefs Around Lizard Island, Australia, Amanda Chan Dec 2014

Examining Predation As A Possible Means Of Controlling Crown-Of- Thorns Starfish (Acanthaster Planci) Outbreaks On Reefs Around Lizard Island, Australia, Amanda Chan

Independent Study Project (ISP) Collection

Since the world’s coral reefs are currently threatened by a variety of different natural and anthropogenic factors, research on protecting coral reefs is pivotal to protect these diverse ecosystems. However, only Indo-Pacific reefs such as the Great Barrier Reef are dying due to a corallivorous echinoderm threat known as the Crown-of-Thorns Starfish (Acanthaster planci). A. planci is a starfish which feeds on coral tissue and can quickly reduce coral cover on a reef during an outbreak. Although scientists are still unsure as to what causes these outbreaks, one suggestion is the predator-removal theory. The predator removal-theory states that major predators …


Freeing Nemo, Stephanie K. Adamczak Nov 2014

Freeing Nemo, Stephanie K. Adamczak

SURGE

Floating on the surface of the water, I observe the life teeming below me. The waves were carrying my body further and further into the beautiful reef; but all I was conscious of was the cleaner wrasse below bouncing from fish to fish, the parrotfish scraping algae from the coral, and the anemone protecting the ornate clownfish living within.

Coral-Fish Dynamics And Interactions: A Case Study Of Grand Cayman, Eileen Shea Davis Jun 2014

Coral-Fish Dynamics And Interactions: A Case Study Of Grand Cayman, Eileen Shea Davis

Lawrence University Honors Projects

To better understand the ecological interactions of coral reefs, it is important to understand the mechanisms that control the distribution and abundance of reef-building corals as well as the mechanisms that control the diversity and abundance of the fish community that inhabits these reef habitats. The purpose of this study was to identify specific coral-fish interactions among the reefs of Grand Cayman in order to gain insight into the biological effects of fish on the assemblage of hard corals. Using data collected by the Lawrence University Marine Program (LUMP), a number of exploratory statistical analyses were run in order to …

All HMC Faculty Publications and Research

The family Xeniidae (Octocorallia) constitutes an abundant benthic component on many Indo-West Pacific coral reefs and is ecologically important in the Red Sea. The genus Ovabunda Alderslade, 2001 was recently established to accommodate previous Xenia species with sclerites comprised of a mass of minute corpuscle-shaped microscleres. The aim of the present study was to examine type material of Xenia species in order to verify their generic affiliation. We present here a comprehensive account of the genus Ovabunda, using scanning electron microscopy to depict sclerite microstructure. We assign three Xenia species to the genus: O. ainex comb. n., O. …

Reported Incidences Of Parasitic Infections In Marine Mammals From 1892 To 1978, John R. Felix

Zea E-Books Collection

The role of parasites in the lives and deaths of marine mammals has been scrutinized by biologists for decades, but the scientific literature prior to 1978 has been difficult to acquire and time-consuming to search. Now this new and extensive bibliography gives researchers a convenient resource for reviewing the classical literature on parasites of marine mammals so that historical infection prevalence and geographical distribution can be easily and properly assessed. This book contains detailed information about accepted (or suspected) taxonomic synonyms and geographical information about the host and/or parasite, covering the parasite groups Acanthocephala, Acarina, Anoplura, Cestoda, Nematoda, and Trematoda, …


Big Babies, Big Mammas?: Relationship Of Leatherback Hatchling Size And Mother Size, Shane Morales, Violet Campbell, Kelly Stewart Aug 2013

Big Babies, Big Mammas?: Relationship Of Leatherback Hatchling Size And Mother Size, Shane Morales, Violet Campbell, Kelly Stewart

STAR Program Research Presentations

Individual leatherback hatchlings vary in size when compared to individuals from other nests, as well as individuals from the same nest. It is thought that many factors affect hatchling size but that one of the most influential factors is maternal size. Of all the aspects of a mother which could affect hatchling size, evidence for question concerning influence of mother size is determinable within the field using minimal tools and basic statistical analysis. If a direct correlation exists between mother size and hatchling size then the claim can be made that larger mothers produce larger offspring while smaller mothers produce …


Behavioral Variation Between Two Clades Of Leptasterias Spp., Ashley N. Contreras Aug 2013

Behavioral Variation Between Two Clades Of Leptasterias Spp., Ashley N. Contreras

STAR Program Research Presentations

Leptasterias spp. are six-rayed sea stars found along the rocky intertidal of the northeast Pacific Alaska to Santa Catalina Island, southern California. In central California, three clades of Leptasterias are found in separate or mixed populations, in diverse habitats that range from shallow pools of seagrass and algae to bare rock exposed to crashing waves. Initial field observations of two clades from different locations suggested that behavioral variation may relate to habitat differences among clades. To measure differences in activity, the righting response was timed at both field sites. As a result of behavioral variation observed in the field, more …


Decades-Long Social Memory In Bottlenose Dolphins, Jason N. Bruck Jul 2013

Decades-Long Social Memory In Bottlenose Dolphins, Jason N. Bruck

Faculty Publications

Long-term social memory is important, because it is an ecologically relevant test of cognitive capacity, it helps us understand which social relationships are remembered and it relates two seemingly disparate disciplines: cognition and sociality. For dolphins, long-term memory for conspecifics could help assess social threats as well as potential social or hunting alliances in a very fluid and complex fission-fusion social system, yet we have no idea how long dolphins can remember each other. Through a playback study conducted within a multi-institution dolphin breeding consortium (where animals are moved between different facilities), recognition of unfamiliar versus familiar signature whistles of …

Spatial And Oceanographic Factors Affecting Black-Legged Kittiwake And Thick-Billed Murre Distributions In The Southeastern Bering Sea, Brian Hoover Oct 2012

Spatial And Oceanographic Factors Affecting Black-Legged Kittiwake And Thick-Billed Murre Distributions In The Southeastern Bering Sea, Brian Hoover

Capstone Projects and Master's Theses

The distribution patterns of Thick-billed Murres (Uria lomvia) and Black-legged Kittiwakes (Rissa tridactyla) in the southeastern Bering Sea were documented at sea during vessel-based surveys in July-August of 2008 and 2009. The relationships of murre and kittiwake densities with environmental variables were investigated using binomial generalized additive models (GAMs) to model the presence or absence of birds, and Gamma-error distribution GAMs to model the positive densities of birds. Environmental variables included oceanographic factors (Chlorophyll, Chlorophyll anomalies, Daily SST, Monthly SST), spatial factors (Distance to nearest colony, Distance to 300m shelf break, Depth), and a temporal factor (Year). Nocturnal surveys were …

Nutritional Content of Rhinoceros Auklet Bill Loads

Dustin E Taylor

Abstract

An adult Rhinoceros Auklet (Cerorhinca monocerata) can only catch and carry a limited amount of prey to their nestlings after a foraging trip. The auklets therefore must maximize their efficiency by bringing back the most proportionally nutritious prey items to their nestlings. The prey carried back to the nesting sites (known as a ‘bill load’) can contain whole fish, as well as parts, most commonly fish heads. This study is aimed to determine whether returning with just heads to the nestlings was proportionally more nutritious than bringing …

A Fish Out Of Water: Gill And Skin Remodeling Promotes Osmo- And Ionoregulation In The Mangrove Killifish Kryptolebias Marmoratus, Danielle M. Leblanc, Chris M. Wood, Douglas S. Fudge, Patricia A. Wright Oct 2010

A Fish Out Of Water: Gill And Skin Remodeling Promotes Osmo- And Ionoregulation In The Mangrove Killifish Kryptolebias Marmoratus, Danielle M. Leblanc, Chris M. Wood, Douglas S. Fudge, Patricia A. Wright

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The euryhaline, amphibious mangrove killifish Kryptolebias marmoratus is known to survive weeks out of water in moist environments. We tested the hypothesis that the skin is a site of osmo- and ionoregulation in K. marmoratus. We predicted that under terrestrial conditions, gill and skin remodeling would result in an enhanced role for skin and a diminished role for the gills in osmo- and ionoregulation. Fish were exposed to water—either freshwater (FW, 1‰) or hypersaline water (saltwater [SW], 45‰)—or air over a moist surface of FW or SW for 9 d and then recovered in water. When fish were emersed …


Interspecific Variation In Palatability Suggests Cospecialization Of Antipredator Defenses In Sea Hares, Kimberly K. Takagi, Nadia N. Ono, William G. Wright Jan 2010

Interspecific Variation In Palatability Suggests Cospecialization Of Antipredator Defenses In Sea Hares, Kimberly K. Takagi, Nadia N. Ono, William G. Wright

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Prey species often deploy different kinds of antipredator defenses, which can interact with each other in ways that are not yet completely understood. Much research into these interactions has utilized gastropod mollusks, usually focusing (in part) on the protective utility of the gastropod shell. This makes the evolutionary reduction of the shell in the opisthobranch gastropods (marine slugs) particularly interesting. This loss of protective function of the shell is associated with the evolution of alternative defenses. Particularly well studied are chemical defenses, especially those using secondary metabolites derived from food resources. As a first step toward understanding interspecific variation in …


Morphological Differences Among Eyeless Amphipods In The Genus Stygobromus Dwelling In Different Subterranean Habitats, David C. Culver, John R. Holsinger, Mary C. Christman, Tanja Pipan Jan 2010

Morphological Differences Among Eyeless Amphipods In The Genus Stygobromus Dwelling In Different Subterranean Habitats, David C. Culver, John R. Holsinger, Mary C. Christman, Tanja Pipan

Biological Sciences Faculty Publications

The amphipod genus Stygobromus occurs in a variety of subterranean habitats in North America, including caves, phreatic (groundwater) lakes, and superficial subterranean habitats (seeps and epikarst). The habitats share the absence of light but differ in other features, such as pore size of the habitat, available food, and degree of seasonality. Measurements of body size, antennal size, and antennal segment number of type specimens were compared for 56 species occurring in the eastern United States. Except for differences in body size, differences among species in the four different habitats were not significant. Body size was related to relative pore size …
