Observations On Regeneration Of The Pedipalp And Legs Of Scorpions, 2022 Marshall University
Observations On Regeneration Of The Pedipalp And Legs Of Scorpions, Martin Watz, Jason A. Dunlop
An Opisthacanthus asper (Peters, 1861) (Hormuridae) shows a relatively rare example of pedipalp regeneration in which the lost tibia and tarsus was replaced by a smaller, curved element of uncertain homology to either the fixed or free finger. A comparable abnormal palp described in the literature hints that pedipalps can only regenerate a structure of this form, regardless of the site of amputation. An Olivierus caucasicus (Nordmann, 1840) (Buthidae) is described in which claws (pretarsus) of leg III regenerated directly at the distal end of the tibia, while in leg IV the claws regenerated at the end of a truncated ...

The objective of this case-control study was to determine if feeding behavior data collected from an automated milk feeder (AMF) could be used to predict neonatal calf diarrhea (NCD) in the days surrounding diagnosis in pre-weaned group housed dairy calves. Data were collected from two research farms in Ontario between 2017 and 2020 where calves fed using an AMF were health scored daily and feeding behavior data (milk intake (mL/d), drinking speed (mL/min), number of rewarded or unrewarded visits) was collected. Calves with NCD were pair matched to healthy controls (31 pairs) by farm, gender, and age at ...

Kinorhynch Diversity In The Southern Gulf Of Mexico And A Description Of Dracoderes Chaac Sp. Nov., Stephen C. Landers, Kellan Hoffman, Nuria Sanchez, Martin Sorensen
Gulf and Caribbean Research
Sediment collections from the southern Gulf of Mexico between the Texas—Mexico border and the Yucatán Peninsula have resulted in many new kinorhynch species distribution records and the finding and taxonomic description of a new species, Dracoderes chaac sp. nov. This study focused on the non—echinoderid members of the Phylum Kinorhyncha, many of which are rare or restricted to only a few locations. A total of 136 specimens were identified from 24 sediment stations, distributed among the following species: Antygomonas gwenae, Campyloderes vanhoeffeni, Centroderes readae, Condyloderes flosfimbriatus, Co. rohalorum, Cristaphyes panamensis, Dracoderes chaac sp. nov., Leiocanthus corrugatus, L. langi ...
Evaluating Common Raven Take For Greater Sage-Grouse In Oregon’S Baker County Priority Conservation Area And Great Basin Region, 2022 U.S. Fish and Wildlife Service
Evaluating Common Raven Take For Greater Sage-Grouse In Oregon’S Baker County Priority Conservation Area And Great Basin Region, Frank F. Rivera-Milán, Peter S. Coates, Jacqueline B. Cupples, Michael Green, Patrick K. Devers
The common raven (Corvus corax; raven) is a nest predator of species of conservation concern, such as the greater sage-grouse (Centrocercus urophasianus). Reducing raven abundance by take requires authorization under the Migratory Bird Treaty Act. To support U.S. Fish and Wildlife Service’s take decisions (e.g., those that authorize killing a specified proportion or number of individuals annually in a defined area), including the most recent one for Oregon’s Baker County Priority Area for Conservation (PAC), we modeled raven population dynamics under hypothetical scenarios with take rates ranging from below to above the maximum sustained yield (MSY ...

Movement Probabilities Of Bigheaded Carps (Hypophthalmichthys Spp.) In The Illinois River Estimated From Markov Chain Monte Carlo Methods, A. A. Coulter, M. K. Brey, M. Lubjeko, J. L. Kalis, D. P. Coulter, D. C. Glover, G. W. Whitledge, J. E. Garvey
NRM Departmental Data Sets
Previously published work used program MARK to estimate parameters for multistate models for Bighead Carp (Hypophthalmichthys nobilis) and Silver Carp (H. molitrix) (Coulter et al. 2018) movements in the Illinois River. Multistate models estimate transition probability (psi), survival probability (S), and detection probability (p) and models with those parameters varying by state and time (state*time), just state (state), just time (time), and neither (.) were evaluated for each species (Coulter et al. 2018). Using the format of the top model for each species identified in Coulter et al. (2018), Markov Chain Monte Carlo (MCMC) methods were used to provide a ...
Effect Of Nest Box Temperature Mitigation Treatments On Nest Success And Nestling Condition In A Southeastern Population Of Eastern Bluebirds (Sialia Sialis), 2022 Georgia College & State University
Effect Of Nest Box Temperature Mitigation Treatments On Nest Success And Nestling Condition In A Southeastern Population Of Eastern Bluebirds (Sialia Sialis), Christopher G. Horacek, Katie Stumpf, Wayne Powell
Graduate Research Posters
Understanding behavioral responses of wildlife to climate change will be important as global temperatures continue to rise. Effects of rising temperatures may impact many species, including those that breed in seemingly protected nests, such as cavity nesting birds. Variations in nest cavity microclimate during the early development of secondary cavity nesting passerines may affect the growth of offspring and impact nesting success and survival. We examined the effect of two heat mitigation treatments (white exterior, n=11, and an internal foil heat shield, n=16) and nest box opening orientation (north, south, east, west) on internal nest box temperatures and ...

Genome-Wide Analysis Of Acute Low Salinity Tolerance In The Eastern Oyster Crassostrea Virginica And Potential Of Genomic Selection For Trait Improvement, 2022 Virginia Institute of Marine Science
Genome-Wide Analysis Of Acute Low Salinity Tolerance In The Eastern Oyster Crassostrea Virginica And Potential Of Genomic Selection For Trait Improvement, Alexandra J. Mccarty, Standish K. Allen Jr., Louis V. Plough
As the global demand for seafood increases, research into the genetic basis of traits that can increase aquaculture production is critical. The eastern oyster (Crassostrea virginica) is an important aquaculture species along the Atlantic and Gulf Coasts of the United States, but increases in heavy rainfall events expose oysters to acute low salinity conditions, which negatively impact production. Low salinity survival is known to be a moderately heritable trait, but the genetic architecture underlying this trait is still poorly understood. In this study, we used ddRAD sequencing to generate genome-wide single-nucleotide polymorphism (SNP) data for four F2 families to ...

Impacts Of Plastic Pollution On A Pelagic Marine Mammal, The Northern Elephant Seal, 2022 University of the Pacific
Impacts Of Plastic Pollution On A Pelagic Marine Mammal, The Northern Elephant Seal, Lauren M. Kashiwabara
University of the Pacific Theses and Dissertations
As plastic pollution increases, top marine predators such as marine mammals are becoming increasingly susceptible to plastic particles and their additives. Plastic particles have been found in gastrointestinal tracts and scat of many marine mammals, and quantifying plastic pollution in those that are pelagic can provide insight into plastic pollution in mesopelagic ecosystems that are just beginning to be analyzed. Adapting well-developed laboratory techniques for microplastic (MP) isolation (i.e. density separation and chemical digestion), I isolated MPs from the scat of the deepest diving pinniped, the northern elephant seal (NES), and found that100% of scat samples (n=11) contained ...
A Deterministic Model For Understanding Nonlinear Viral Dynamics In Oysters, 2022 Virginia Institute of Marine Science
A Deterministic Model For Understanding Nonlinear Viral Dynamics In Oysters, Qubin Qin, Jian Shen, Kimberly S. Reece
Contamination of oysters with a variety of viruses is one key pathway to trigger outbreaks of massive oyster mortality as well as human illnesses, including gastroenteritis and hepatitis. Much effort has gone into examining the fate of viruses in contaminated oysters, yet the current state of knowledge of nonlinear virus-oyster interactions is not comprehensive because most studies have focused on a limited number of processes under a narrow range of experimental conditions. A framework is needed for describing the complex nonlinear virus-oyster interactions. Here, we introduce a mathematical model that includes key processes for viral dynamics in oysters, such as ...
Discard Mortality Of Sea Scallops Placopecten Magellanicus Following Capture And Handling In The U.S. Dredge Fishery, 2022 Virginia Institute of Marine Science
Discard Mortality Of Sea Scallops Placopecten Magellanicus Following Capture And Handling In The U.S. Dredge Fishery, David Rudders, Hugues P. Benoıt, Ryan J. Knotek, John A. Mandelman, Sally Roman, James A. Sulikowski
Discard mortality can represent a potentially significant source of uncertainty for both stock assessments and fishery management measures. While the family Pectinidae is considered to be robust to the capture and handling process, understanding species-specific discard mortality rates is critical to characterize both population dynamics and to develop regulatory measures to meet management objectives. The discard mortality rate for the U.S. dredge fishery of sea scallop Placopecten magellanicus was estimated empirically via a retention study aboard industry vessels under commercial conditions. Over 16,000 sea scallops were assessed via a composite index of scallop vitality that consisted of semiqualitative ...
Mechanisms Of Programmed Nutrition In Finishing Cattle In Vivo And Ruminal Parameters Of Amaize Supplementation In Vitro, Amanda Pesqueira Schiff
Theses and Dissertations--Animal and Food Sciences
Programmed Nutrition Beef Program (Alltech Inc.) is a dietary supplement that contains Aspergillus oryzae fermentation extract with α-amylase activity that could reduce the use of feed additives such as monensin and tylosin in conventional feedlot diets. This study examines the changes in rumen fermentation resulting from feeding monensin/tylosin and Programmed Nutrition Beef Finisher. The goal was to determine if these shifts in rumen fermentation contribute to the Programmed Nutrition response observed in vivo. This study also analyzes how different levels of α-amylase (Amaize)supplementation impacts feedstuff degradation and utilization in vitro. In vivo experiment used eight steers in a ...
Investigating Public Support For Biosecurity Measures To Mitigate Pathogen Transmission Through The Herpetological Trade, 2022 Old Dominion University
Investigating Public Support For Biosecurity Measures To Mitigate Pathogen Transmission Through The Herpetological Trade, Elizabeth F. Pienaar, Diane J. Episcopio-Sturgeon, Zachary T. Steele
Biological Sciences Faculty Publications
The expanding global trade in herpetofauna has contributed to new infectious disease dynamics and pathways that allow for the rapid spread of pathogens geographically. Improved biosecurity is needed to mitigate adverse biodiversity, economic and human health impacts associated with pathogen transmission through the herpetological trade. However, general lack of knowledge of the pathogen transmission risks associated with the global trade in herpetofauna and public opposition to biosecurity measures are critical obstacles to successfully preventing pathogen transmission. In 2019 we administered a survey to 2,007 members of the public in the United States of America to ascertain their support for ...

Marine species and ecosystems are widely affected by anthropogenic stressors, ranging from pollution and fishing to climate change. Comprehensive assessments of how species and ecosystems are impacted by anthropogenic stressors are critical for guiding conservation and management investments. Previous global risk or vulnerability assessments have focused on marine habitats, or on limited taxa or specific regions. However, information about the susceptibility of marine species across a range of taxa to different stressors everywhere is required to predict how marine biodiversity will respond to human pressures. We present a novel framework that uses life-history traits to assess species’ vulnerability to a ...

Monitoring Extinction Risk And Threats Of The World's Fishes Based On The Sampled Red List Index, Rafael Miranda, Imanol Miqueleiz, William Darwall, Catherine Sayer, Nicholas K. Dulvy, Kent E. Carpenter, Beth Polidoro, Nadia Dewhurst-Richman, Caroline Pollock, Craig Hilton-Taylor, Robin Freeman, Ben Collen, Monika Böhm
Biological Sciences Faculty Publications
Global biodiversitytargets require us to identify species at risk of extinction and quantify status and trends of biodiversity. The Red List Index (RLI) tracks trends in the conservation status of entire species groups over time by monitoring changes in categories assigned to species. Here, we calculate this index for the world’s fishes in 2010, using a sampled approach to the RLI based on a randomly selected sample of 1,500 species, and also present RLI splits for freshwater and marine systems separately. We further compare specific traits of a worldwide fish list to our sample to assess its representativeness ...
Development Of An Individual-Based Tag Recapture Model To Benchmark Biomass And Harvest Rates In An Iconic Lobster Fishery, 2022 Virginia Institute of Marine Science
Development Of An Individual-Based Tag Recapture Model To Benchmark Biomass And Harvest Rates In An Iconic Lobster Fishery, Simon De Lestang, John Hoenig, Jason How
The West Coast Rock Lobster Managed Fishery (WCRLMF) moved from input to output controls in 2010. This change affected the relativity of fishery-based data sources (e.g., catch rates and landed size composition), making the assessment of the fishery problematic. A novel examination of the stock dynamics was required to ensure the robustness of the stock assessment and associated management arrangements. This study derived estimates of current biomass levels and harvest rates from the release of over 60,000 tagged western rock lobsters (Panulirus cygnus). A Brownie tag-recapture (BTR) model was initially implemented to provide an assessment on a fishery-wide ...
