Multi-Omics Reveals Largely Distinct Transcript- And Protein-Level Responses To The Environment In An Intertidal Mussel, Lani U. Gleason, Florian J. Fekete, Richelle L. Tanner, W. Wesley Dowd
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Organismal responses to stressful environments are influenced by numerous transcript- and protein-level mechanisms, and the relationships between expression changes at these levels are not always straightforward. Here, we used paired transcriptomic and proteomic datasets from two previous studies from gill of the California mussel, Mytilus californianus, to explore how simultaneous transcript and protein abundance patterns may diverge under different environmental scenarios. Field-acclimatized mussels were sampled from two disparate intertidal sites; individuals from one site were subjected to three further treatments (common garden, low-intertidal or high-intertidal outplant) that vary in temperature and feeding time. Assessing 1519 genes shared between …

Reef Fish Wariness Behavior: Fish Flight Initiation Distance Mediated By Territoriality And Body Size In Three Reef Sites Off The Western Coast Of Isla Colón, Bocas Del Toro, Panamá, Alina G. Irvine
Independent Study Project (ISP) Collection
Coral reefs are highly productive and diverse underwater ecosystems, providing a variety of environmental services including sand generation, nutrient processing, fish supply, and tourism. However, coral reefs have been increasingly impacted by natural and anthropogenic disturbances, which has negatively affected fish security within their environment. A significant observation is the reduction in evasive behaviors among reef fish in marine reserves compared to those exposed to anthropogenic threats. The present research aims to investigate the factors mediating fish wariness behavior through an exploration of the roles of territoriality and body size on fish flight initiation distance (FID). FID is the distance …
On The Rocks, Below The Rocks: A Study Of Intertidal Life In The Low, Middle And High Zones Of The Puerto Cabuyal – Punta San Clemente Marine Reserve During An El Niño Event, Juliana M. Ferrer
Independent Study Project (ISP) Collection
The rocky intertidal zone is one of the most difficult environments for organisms to survive in due to its harsh biotic and abiotic conditions. As such, it is also one of the best indicators of climate change and an important barrier to beach erosion. This study looked at the rocky intertidal zone of the Puerto Cabuyal-Punta San Clemente Marine Reserve in the Manabí province of Ecuador, with a focus on observing and identifying the organisms found in the area. Data was collected along 30 m transects at varying elevations along the shore using quadrants of two sizes: 50x50 cm for …

The Uses And Limitations Of Citizen Science For Monitoring The Australian Grey Nurse Shark (Carcharias Taurus) Population, Leah Corckran
Independent Study Project (ISP) Collection
iNaturalist is a citizen science photographic database, which is an underutilized resource in photographic identification research studies. Grey nurse sharks are critically endangered and there is a lack of knowledge regarding the estimated population size, longevity, and interactions with fisheries of this species off the coasts of Australia. To determine how photos submitted to iNaturalist can be used in Carcharias taurus conservation, the photographs were evaluated on a number of criteria including: location, date, visibility of spot patterns, visible sex characteristics, and visible injuries. In total, 814 photographs of grey nurse sharks were obtained from the iNaturalist database. Only 23.2% …

Organism Communities On Giant Clam Shells As Compared To The Surrounding Substrate In Reefs Around Lizard Island, Queensland, Gayatri Singla
Independent Study Project (ISP) Collection
Coral reef ecosystems are facing destruction at the hands of anthropogenic climate change. Therefore, it is essential that we move to better understand the ecosystem functions of the organisms present in reefs. One such family whose ecosystem function we are unfamiliar with are the giant clams (family Cardiidae). As unique and abundant macrofauna, they have the potential to play an important role in their environment. The goal of our study was to determine how giant clams function as settlement substrata. We conducted 151 observational surveys of epibionts residing on living giant clam shells and of the organism communities in the …

South Coast Offshore Crustacean Resource Of Western Australia Harvest Strategy, Department Of Primary Industries And Regional Development, Western Australia
Fisheries management papers
Harvest strategies for aquatic resources in Western Australia (WA) that are managed by the Department of Primary Industries and Regional Development (DPIRD, the Department) are formal documents that ensures decision-making processes are consistent with the principles of Ecologically Sustainable Development (ESD; Fletcher 2002) and Ecosystem Based Fisheries Management (EBFM; Fletcher et al. 2012). The objectives of ESD are reflected in the objects of the Fish Resources Management Act 1994 (FRMA) and the Aquatic Resources Management Act 2016 (ARMA), which is anticipated replace the FRMA once enacted. At this point, the Fish Resources Management Regulations 1995 (FRMR) is also anticipated to …
Utility Of Body And Otolith Morphometry To Discriminate Cryptic Juveniles Of Two Sympatric Red Snappers (Perciformes: Lutjanidae), Miwa Takahashi, Corey B. Wakefield, Stephen J. Newman, Kyle B. Hillcoat, Benjamin J. Saunders, Euan S. Harvey
Utility Of Body And Otolith Morphometry To Discriminate Cryptic Juveniles Of Two Sympatric Red Snappers (Perciformes: Lutjanidae), Miwa Takahashi, Corey B. Wakefield, Stephen J. Newman, Kyle B. Hillcoat, Benjamin J. Saunders, Euan S. Harvey
Fisheries Research Articles
The sympatric red snappers, Lutjanus erythropterus and Lutjanus malabaricus, are highly valued by commercial and recreational fishers along the tropical northern coasts of Australia and throughout their distribution. Studies on the life history and ecology of these congeners are confounded by difficulties in distinguishing the cryptic juveniles of each species (i.e., < 200 mm total length). This study aimed to validate a robust and cost-effective method to discriminate these juveniles using body and/or otolith morphometric data in a multivariate analysis. Juvenile samples were collected from the northwest (n = 71) and northeast (n = 19) coasts of Australia, and species identification was confirmed using DNA barcoding. The most parsimonious multivariate models achieved accurate species prediction rates of 98.8%, which consisted of just three body variables (dorsal fin length, the distance from the snout to the anterior edge of the eye, and either jaw length or distance from the snout to the preoperculum). The high level of discrimination for these cryptic juveniles highlights the robustness of this morphometric approach. The slightly lower rate of discrimination using otolith morphology (84.9%) was associated with greater regional variation in L. malabaricus between the northwest and northeast coasts. Slight variations in otolith shape are typically used to determine stock structure, which highlights the potential need to collect samples over a broader area of a species geographic range when using an otolith morphometric discrimination model. The method outlined in this study could be applied to distinguish other cryptic congeneric fish species, including from archived otolith collections. Moreover, this method has the potential to be utilized in assessing species compositions using body measurements from in situ stereo-video.

Engineering Faculty Articles and Research
Armor is a multipurpose set of structures that has evolved independently at least 30 times in fishes. In addition to providing protection, armor can manipulate flow, increase camouflage, and be sexually dimorphic. There are potential tradeoffs in armor function: increased impact resistance may come at the cost of maneuvering ability; and ornate armor may offer visual or protective advantages, but could incur excess drag. Pacific spiny lumpsuckers (Eumicrotremus orbis) are covered in rows of odontic, cone-shaped armor whorls, protecting the fish from wave driven impacts and the threat of predation. We are interested in measuring the effects of …
Expression Of The Rag-1 Gene In Larval Yellowtail Kingfish, Gabriella Peluso
Expression Of The Rag-1 Gene In Larval Yellowtail Kingfish, Gabriella Peluso
Honors College
Aquaculture has taken over from capture fisheries as a primary global provider of seafood products. Seriola lalandi, or Yellowtail kingfish, has become a species of interest, as it is a fish notable for its marketability and culinary desirability. With the expansion of aquaculture and the increased amount of high-level operating facilities comes an increased risk of disease outbreaks. There are methods commonly used within these facilities for disease control, including incorporating nutritional feeds into the fishes’ diets, safe husbandry practices, and vaccinations. While these methods can be effective, they have caveats that must be considered. Adequate diets and improved …
I Ain't Afraid Of No Crab: Intertidal Gastropod Littorina Littorea Behavioral Response To Predation Risk By Carcinus Maenas, Isabelle Erin Smy
I Ain't Afraid Of No Crab: Intertidal Gastropod Littorina Littorea Behavioral Response To Predation Risk By Carcinus Maenas, Isabelle Erin Smy
Honors College
Littorina littorea is an intertidal, invasive gastropod species common in the Gulf of Maine. In this paper, I studied the avoidance and risk-reducing behavioral responses of L. littorea to predation risk by invasive crustacean species Carcinus maenas. Avoidance and risk-reducing behavior in this study are defined by the tendency to move towards the edge and out of a simulated tide pool and the tendency to reduce feeding. The goal of this study was to determine whether the exposure to chemical cues of predators resulted in an increase in avoidance behavior, risk-reducing behavior, and a reduction in the time before the …
Rocky Intertidal Community Structure Along An Upwelling Gradient Between Playa Venao And Nueva Gorgona On Panama’S Pacific Coast, Claire Brady
Independent Study Project (ISP) Collection
Ecological research on rocky intertidal ecosystems has increasingly focused on the regional oceanographic processes that shape community structure over functional group interactions. Intertidal communities’ dependence on onshore and offshore transport of intertidal species larvae, dissolved inorganic nutrients, and phytoplankton signal that upwelling and nearshore currents can have an influential role in determining the growth and composition of intertidal systems. The community structure of rocky intertidal areas was compared between two locations along an upwelling gradient in the Gulf of Panama: Nueva Gorgona, with intermittent seasonal upwelling, and Playa Venao, with fringe seasonal upwelling. The surface cover of algae, barnacles, and …
