Journal of Marine Science and Technology–Taiwan

Three newly recorded gobiid genera of coral-reef gobies have been collected and examined by scuba diving in the Dongsha Atoll, also known as the Pratas Islands, South China Sea. They are Feia Smith, 1959; Sueviota Winterbottom and Hoese, 1988; and Trimmatom Winterbottom and Emery, 1981. These three genera were formerly unrecorded in the Dongsha Atoll and all Taiwanese waters before this paper. One representing species was found for each gobiid genus. The diagnosis for these three newly recorded species and genera will be provided in this paper.

Changes in the distribution and abundance of invasive species can have far-reaching ecological consequences. Programs to control invaders are common but gauging the effectiveness of such programs using carefully controlled, large-scale field experiments is rare, especially at higher trophic levels. Experimental manipulations coupled with long-term demographic monitoring can reveal the mechanistic underpinnings of interspecific competition among apex predators and suggest mitigation options for invasive species. We used a large-scale before-after control-impact removal experiment to investigate the effects of an invasive competitor, the barred owl (Strix varia), on the population dynamics of an iconic old-forest native species, the northern spotted owl …

Craniometric Analysis Of European Rabbit (Oryctolagus Cuniculus) Breeds To Trace Out Intraspecific And Inter Gender Morphometric Variations, Muhammad Rizwan, Rana Manzoor Ahmad, Abdul Majid Khan, Misbah Khalid, Muhammad Wajid

Journal of Bioresource Management

The family Liproidae expresses the significant variation of morphometric features at species level. In already available literature on the European rabbit (Oryctolagus cuniculus) the idea is proposed that there can be variation in the morphometric character of different breeds of Oryctolagus cuniculus but there are negligible scientific research base evidences for it. So in this study interbreed craniometric comparison of the European rabbit is carried out to trace out their intergender and intraspecific morphometric variations. The study material consists of 32 sexually mature rabbits belong to two breeds of European rabbit that are New Zealand rabbit (eight males and …

Classifying Ingestive Behavior Of Dairy Cows Via Automatic Sound Recognition, Guoming Li, Yijie Xiong, Qian Du, Zhengxiang Shi, Richard S. Gates

Department of Animal Science: Faculty Publications

Determining ingestive behaviors of dairy cows is critical to evaluate their productivity and health status. The objectives of this research were to (1) develop the relationship between forage species/heights and sound characteristics of three different ingestive behaviors (bites, chews, and chew-bites); (2) comparatively evaluate three deep learning models and optimization strategies for classifying the three behaviors; and (3) examine the ability of deep learning modeling for classifying the three ingestive behaviors under various forage characteristics. The results show that the amplitude and duration of the bite, chew, and chew-bite sounds were mostly larger for tall forages (tall fescue and alfalfa) …

Pilot-Scale H2S And Swine Odor Removal System Using Commercially Available Biochar, Kyoung S. Ro, Brian Woodbury, Mindy Spiehs, Ariel A. Szogi, Philip J. Silva, Okhwa Hwang, Sungback Cho

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Although biochars made in laboratory seem to remove H2S and odorous compounds effectively, very few studies are available for commercial biochars. This study evaluated the efficacy of a commercial biochar (CBC) for removing H2S and odorous volatile organic compounds (VOCs). We found that the well-known Ergun equation may not be adequate in predicting pressure drop for properly sizing a ventilation system. The H2S breakthrough adsorption capacity of the CBC was 2.51 mg/g under humid conditions, which was much higher than that for dry conditions. The breakthrough capacity increased with the influent concentration of H2S. The efficacy of a pilot-scale biochar …

Roman L. Hruska U.S. Meat Animal Research Center: Reports

The continuous development and application of technology for genetic improvement is a key element for advancing sheep production in the United States. The US sheep industry has contracted over time but appears to be at a juncture where a greater utilization of technology can facilitate industry expansion to new markets and address inefficiencies in traditional production practices. Significant transformations include the increased value of lamb in relation to wool, and a downtrend in large-scale operations but a simultaneous rise in small flocks. Additionally, popularity of hair breeds not requiring shearing has surged, particularly in semi-arid and subtropical US environments. A …

Influence Of Estradiol On Bovine Trophectoderm And Uterine Gene Transcripts Around Maternal Recognition Of Pregnancy, Emmalee J. Northrop-Albrecht, Jerica J.J. Rich, Robert A. Cushman, Runan Yao, Xijin Ge, George A. Perry

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Embryo survival and pregnancy success is increased among animals that exhibit estrus prior to fixed time-artificial insemination, but there are no differences in conceptus survival to d16. The objective of this study was to determine effects of preovulatory estradiol on uterine transcriptomes, select trophectoderm (TE) transcripts, and uterine luminal fluid proteins. Beef cows/heifers were synchronized, artificially inseminated (d0), and grouped into either high (highE2) or low (lowE2) preovulatory estradiol. Uteri were flushed (d16); conceptuses and endometrial biopsies (n = 29) were collected. RNA sequencing was performed on endometrium. Real-time polymerase chain reaction (RT-PCR) was performed on TE (n = 21) …

Imputation Of Missing Count Data Of Recreational Boat Retrievals From Remote Camera Surveys In The Perth Metropolitan Region, Western Australia, E. Afrifa-Yamoah, S.M Taylor, Cameron J. Desfosses, U. A. Mueller

Fisheries Research Reports

In Western Australia (WA), remote cameras have been used to monitor boating activity at boat ramps since 2006 to assist in ongoing recreational fishing surveys. These monitoring schemes are useful tools to validate boating activity (defined here as the number of retrievals) and to corroborate estimates of recreational fishing effort obtained from other surveys. This is because remote cameras (also referred to as digital cameras) can provide complete coverage (i.e. 24 hours, 365 days) of boating activities.

Breed And Heterotic Effects For Mature Weight In Beef Cattle, Madeline J. Zimmermann, Larry A. Kuehn, Matthew L. Spangler, R. M. Thallman, Warren M. Snelling, Ronald M. Lewis

Department of Animal Science: Faculty Publications

Cow mature weight (MWT) is heritable and affects the costs and efficiency of a breeding operation. Cow weight is also influenced by the environment, and the relationship between the size and profitability of a cow varies depending on production system. Producers, therefore, need tools to incorporate MWT in their selection of cattle breeds and herd replacements. The objective of this study was to estimate breed and heterotic effects for MWT using weight-age data on crossbred cows. Cow's MWT at 6 yr was predicted from the estimated parameter values-asymptotic weight and maturation constant (k)-from the fit of the Brody function to …

Plumage Characteristics Of The Long-Eared Owl (Asio Otus) In The Visible And Ultraviolet Spectra Of Light, Emily Griffith

All NMU Master's Theses

The study of plumage is a foundational aspect of ornithology, and the features of even a single feather can provide valuable information on an individual’s health, sex, or age. Recent discoveries on the abilities of birds to see in the ultraviolet (UV) spectrum has led to study of the UV-reactive characteristics of bird plumage and the biological significance of such plumage. Long-eared owls (Asio otus) possess a demonstrative capability to see UV light, and their plumage contains deposits of UV-sensitive pigments that fluoresce bright red when exposed to UV light. Little is understood about the origin and function of these …

Nicarbazin As An Oral Contraceptive In Eared Doves, Lourdes Olivera, Silvia Pereyra, Georgget Banchero, Guillermo Tellechea, Jorge Sawchik, Michael L. Avery, Ethel Rodríguez

United States Department of Agriculture Wildlife Services: Staff Publications

Eared doves (Zenaida auriculata) are responsible for substantial losses in cereal and oil crops as well as in dairy and feedlot production in the southern cone of South America. Various strategies have been shown to be effective in reducing damage at the farm scale, but in some scenarios, it is necessary to also incorporate population control methods due to excessive bird population size. An alternative approach to reduce pest bird populations is the use of contraceptive methods, minimizing the impact on the environment and non-target populations. Nicarbazin is registered in the United States as a contraceptive for Branta …

Effects Of Early Corticosterone Treatment On Vocal Babbling In Wild Green-Rumped Parrotlets (Forpus Passerinus), Celia Rose Mclean

Theses and Dissertations

The stress axis of the endocrine system allows for animals to respond to environmental stressors in contextually appropriate ways. Elevated levels of the stress hormone corticosterone (CORT) in male songbirds can result in compromised song learning ability. Parrots form a sister group to songbirds, but it is unknown whether CORT affects vocal development in parrots. The goal of this study was to assess the effects of CORT supplements in green-rumped parrotlets (Forpus passerinus), a free-ranging parrot species in Venezuela. Bouts of vocal babbling were extracted from nest box videos and analyzed. CORT supplementation resulted in differences in babbling …

Avian Influenza A Virus Susceptibility, Infection, Transmission, And Antibody Kinetics In European Starlings, Jeremy W. Ellis, J. Jeffrey Root, Loredana M. Mccurdy, Kevin T. Bentler, Nicole L. Barrett, Kaci K. Vandalen, Katherine L. Dirsmith, Susan A. Shriner

United States Department of Agriculture Wildlife Services: Staff Publications

Avian influenza A viruses (IAVs) pose risks to public, agricultural, and wildlife health. Bridge hosts are spillover hosts that share habitat with both maintenance hosts (e.g., mallards) and target hosts (e.g., poultry). We conducted a comprehensive assessment of European starlings (Sturnus vulgaris), a common visitor to both urban and agricultural environments, to assess whether this species might act as a potential maintenance or bridge host for IAVs. First, we experimentally inoculated starlings with a wild bird IAV to investigate susceptibility and replication kinetics. Next, we evaluated whether IAV might spill over to starlings from sharing resources with a …

Mesopredator Frugivory Has No Effect On Seed Viability And Emergence Under Experimental Conditions, John P. Draper, Trisha B. Atwood, Noelle G. Beckman, Karin M. Kettenring, Julie K. Young

United States Department of Agriculture Wildlife Services: Staff Publications

Members of the order Carnivora are a unique and important seed disperser who consume and deposit undamaged seeds while providing regular long-distance seed dispersal opportunities. Some members of Carnivora, such as coyotes (Canis latrans), are undergoing range expansions which may help the plant species they consume colonize new locations or replace dispersal services provided by recently extirpated species. In this study, we evaluated aspects of the seed dispersal effectiveness of coyotes and gut passage time to determine the potential dispersal distances for three commonly consumed and commonly occurring plant species (Amelanchier alnifolia, Celtis ehrenbergiana, and Juniperus osteosperma). We also investigated …

Ecological Correlates Of Alligator Snapping Turtle Bite Performance, Ashley Herrin Gagnon

Graduate Theses/Dissertations

The Alligator Snapping Turtle (Macrochelys temminckii) is one of many turtle species facing conservation challenges. Nearly extirpated in the 1980s, it is currently the subject of a head-start initiative, of which, any lasting behavioral or physiological effects were—until now—unknown! To evaluate the ability of captive-reared individuals to excel in natural habitats, and to foresee any future research or conservation challenges regarding this animal, I explored a suite of variables that influence bite performance and behaviors including captive or free-ranging status, and environmental conditions including body temperature and season. My results indicated that free-ranging M. temminckii outperform those residing …

All Theses And Dissertations

Recirculating Aquaculture Systems (RAS) is an emerging technology that is capturing the attention of many in aquaculture due to its ability to produce high-quality seafood using sustainable models. This study explored the waste management of RAS, specifically further treatment technologies, and the potential value-added products from the RAS waste stream that can be reused. Advanced, tertiary, or down-stream treatment technologies available for RAS were investigated through a literature review. Utilizing the constant comparative method and semistructured interviews with stakeholders in RAS, opinions and attitudes were collected about advanced treatment of RAS waste and reuse opportunities presented from value-added products generated …

Estimation Of Breed Effects And Genetic Parameters For Age At Slaughter And Days To Finish In A Multibreed Beef Cattle Population, Lindsay Rae Upperman

Department of Animal Science: Dissertations, Theses, and Student Research

Cattle efficiency during the finishing phase is a crucial factor in determining profit in the beef cattle industry. Economically relevant traits associated with efficient production include age at slaughter (AAS) and days to finish (DtF). Selection to reduce the number of days an animal takes to reach a finish endpoint would ultimately reduce production costs, increase net profits, and result in a more sustainable production system. However, most harvested animals are from commercial herds, necessitating the use of indicator traits from seedstock animals for selection. Potential indicator traits include ultrasound measurements that could be genetically correlated to DtF traits. The …

Farmer Perceptions And Willingness To Pay For Novel Livestock Pest Control Technologies: A Case Of Tsetse Repellent Collar In Kwale County In Kenya, Beatrice W. Muriithi, Nancy G. Gathogo, Gracious M. Diiro, Michael M. Kidoido, Michael Nyangánga Okal, Daniel K. Masiga

All Peer-Reviewed Publications

Tsetse-transmitted Animal African Trypanosomosis (AAT) is one of the most important constraints to livestock development in Africa. Use of trypanocides has been the most widespread approach for the management of AAT, despite the associated drug resistance and health con-cerns associated with drug metabolites in animal products. Alternative control measures that target tsetse fly vectors of AAT, though effective, have been hard to sustain in part because these are public goods applied area-wide. The International Centre of Insect Physiology and Ecology (icipe) and partners have developed and implemented a novel tsetse repellent collar (TRC) applied on animals to limit contact of …

Generation Of Sheep Models Of Cystic Fibrosis By Gene Editing And Cloning, Iuri Viótti Périssé

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cystic Fibrosis (CF) is a genetic disease that affects over 80,000 people worldwide and is caused by mutations that disrupt the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene. This gene encodes a channel protein that regulates ion transport in cells. The most common mutation in the human CFTR gene is F508del, which is characterized by the deletion of a phenylalanine amino acid in the CFTR protein. The second most common mutation is G542X, a protein synthesis “stop” mutation that prevents the production of the CFTR channel protein. An impediment that prevents the further understanding CF is the limited …

Neurotranscriptomic Changes Associated With Chick-Directed Parental Care In Adult Non-Reproductive Japanese Quail, Patricia C. Lopes, Robert De Brujin

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

For many species, parental care critically affects offspring survival. But what drives animals to display parental behaviours towards young? In mammals, pregnancy-induced physiological transformations seem key in preparing the neural circuits that lead towards attraction (and reduced-aggression) to young. Beyond mammalian maternal behaviour, knowledge of the neural mechanisms that underlie young-directed parental care is severely lacking. We took advantage of a domesticated bird species, the Japanese quail, for which parental behaviour towards chicks can be induced in virgin non-reproductive adults through a sensitization procedure, a process that is not effective in all animals. We used the variation in parental responses …

Fisheries Research Articles

Marine fisheries in coastal ecosystems in many areas of the world have historically removed large-bodied individuals, potentially impairing ecosystem functioning and the long-term sustainability of fish populations. Reporting on size-based indicators that link to food-web structure can contribute to ecosystem-based management, but the application of these indicators over large (cross-ecosystem) geographical scales has been limited to either fisheries-dependent catch data or diver-based methods restricted to shallow waters (<20 m) that can misrepresent the abundance of large-bodied fished species. We obtained data on the body-size structure of 82 recreationally or commercially targeted marine demersal teleosts from 2904 deployments of baited remote underwater stereo-video (stereo-BRUV). Sampling was at up to 50 m depth and covered approximately 10,000 km of the continental shelf of Australia. Seascape relief, water depth, and human gravity (i.e., a proxy of human impacts) were the strongest predictors of the probability of occurrence of large fishes and the abundance of fishes above the minimum legal size of capture. No-take marine reserves had a positive effect on the abundance of fishes above legal size, although the effect varied across species groups. In contrast, sublegal fishes were best predicted by gradients in sea surface temperature (mean and variance). In areas of low human impact, large fishes were about three times more likely to be encountered and fishes of legal size were approximately five times more abundant. For conspicuous species groups with contrasting habitat, environmental, and biogeographic affinities, abundance of legal-size fishes typically declined as human impact increased. Our large-scale quantitative analyses highlight the combined importance of seascape complexity, regions with low human footprint, and no-take marine reserves in protecting large-bodied fishes across a broad range of species and ecosystem configurations.

Intensive Hunting Pressure Changes Local Distribution Of Wild Boar, Jakub Drimaj, Jiří Kamler, Radim Plhal, Přemysl Janata, Zdeněk Adamec, Miloslav Homolka

Human–Wildlife Interactions

Wild boar (Sus scrofa) is now an important species of wild ungulates in Central Europe. Next to conflicts of wild boar with agriculture, the main threat of wild boar presence lies in the expansion of African swine fever across Europe. The regulation of the wild boar population is complicated by the high reproduction rate and intelligent behavior of the species, which limits hunting effectiveness. We analyzed the spatial behavior of wild boar in an environment with a lack of natural food resources. The study area consisted of a forest complex (1,283 ha) with 2 areas. In the “risk” …

Effect Of Biochanin A On The Rumen Microbial Community Of Holstein Steers Consuming A High Fiber Diet And Subjected To A Subacute Acidosis Challenge, Brittany E. Harlow, Michael D. Flythe, James L. Klotz, David L. Harmon, Glen E. Aiken

Animal and Food Sciences Faculty Publications

Subacute rumen acidosis (SARA) occurs when highly fermentable carbohydrates are introduced into the diet, decreasing pH and disturbing the microbial ecology of the rumen. Rumen amylolytic bacteria rapidly catabolize starch, fermentation acids accumulate in the rumen and reduce environmental pH. Historically, antibiotics (e.g., monensin, MON) have been used in the prevention and treatment of SARA. Biochanin A (BCA), an isoflavone produced by red clover (Trifolium pratense), mitigates changes associated with starch fermentation ex vivo. The objective of the study was to determine the effect of BCA on amylolytic bacteria and rumen pH during …

Recognizing the imperative to evaluate species recovery and conservation impact, in 2012 the International Union for Conservation of Nature (IUCN) called for development of a “Green List of Species” (now the IUCN Green Status of Species). A draft Green Status framework for assessing species’ progress toward recovery, published in 2018, proposed 2 separate but interlinked components: a standardized method (i.e., measurement against benchmarks of species’ viability, functionality, and preimpact distribution) to determine current species recovery status (herein species recovery score) and application of that method to estimate past and potential future impacts of conservation based on 4 metrics ( …
