Acquisition Of New Function Through Gene Duplication In The Metallocarboxypeptidase Family, Daniel Fajardo, Ritchie Saint Jean, Peter J. Lyons
Acquisition Of New Function Through Gene Duplication In The Metallocarboxypeptidase Family, Daniel Fajardo, Ritchie Saint Jean, Peter J. Lyons
Faculty Publications
Gene duplication is a key frst step in the process of expanding the functionality of a multigene family. In order to better understand the process of gene duplication and its role in the formation of new enzymes, we investigated recent duplication events in the M14 family of proteolytic enzymes. Within vertebrates, four of 23 M14 genes were frequently found in duplicate form. While AEBP1, CPXM1, and CPZ genes were duplicated once through a large-scale, likely whole-genome duplication event, the CPO gene underwent many duplication events within fsh and Xenopus lineages. Bioinformatic analyses of enzyme specifcity and conservation suggested a greater …

Manatees are aquatic mammals that live in a variety of environments. Many of those shallow water environments have murky water, making detection using traditional visual surveys very challenging. Side-scan sonar was first proposed as a tool to detect and study manatees in these complicated habitats in 2005. Here, we summarize the use of this tool from 2005 to 2022 by searching the available literature. Our literature search revealed that this tool is being widely used in more than 20 locations and over 15 countries. All three manatee species are being studied with side-scan sonar. It is most useful in murky …

Assessing the body condition of wild animals is necessary to monitor the health of the population and is critical to defining a framework for conservation actions. Body condition indices (BCIs) are a non-invasive and relatively simple means to assess the health of individual animals, useful for addressing a wide variety of ecological, behavioral, and management questions. The Antillean manatee (Trichechus manatus manatus) is an endangered subspecies of the West Indian manatee, facing a wide variety of threats from mostly human-related origins. Our objective was to define specific BCIs for the subspecies that, coupled with additional health, genetic and …

Biochemical And Genetic Analysis Of Ecm14, A Conserved Fungal Pseudopeptidase, R. Christian Mcdonald, Matthew James Schott, Temitope A. Idowu, Peter J. Lyons
Faculty Publications
© 2020, The Author(s). Background: Like most major enzyme families, the M14 family of metallocarboxypeptidases (MCPs) contains a number of pseudoenzymes predicted to lack enzyme activity and with poorly characterized molecular function. The genome of the yeast Saccharomyces cerevisiae encodes one member of the M14 MCP family, a pseudoenzyme named Ecm14 proposed to function in the extracellular matrix. In order to better understand the function of such pseudoenzymes, we studied the structure and function of Ecm14 in S. cerevisiae. Results: A phylogenetic analysis of Ecm14 in fungi found it to be conserved throughout the ascomycete phylum, with a group of …

Nocturnal Copulation In Glaucous-Winged Gulls Larus Glaucescens, Floyd E. Hayes, James L. Hayward
Faculty Publications
Gulls (Laridae) are primarily diurnal, although many species forage opportunistically at night, and several species copulate at night. We used trail cameras to study time-of-day variation in the rate of copulation by Glaucous-winged Gulls Larus glaucescens in a breeding colony (1500+ pairs) at Protection Island, Washington, USA, from 31 May to 07 June 2018. Copulations (n = 353) occurred at a significantly higher rate during the day (0.82/camera-h) than at night (0.51/camera-h), with 76.3 % of copulations during the day and 23.7 % at night (daylight comprised 66.1 % and darkness comprised 33.9 % of the study period). The …

© 2020, AIDIC Servizi S.r.l. The study on the lignocellulosic material conversion into bio-based platform chemicals, such as levulinic acid (LA), is one of the most promising routes to promote the development of advanced biorefineries. In this work, a dynamic mechanistic model is developed to simulate the LA production from lignocellulosic material. A wide operating range is used to estimate the parameters of the reaction kinetics. Because multi-parameter estimation problem is complex, a genetic algorithm-based optimization procedure is used to determine the optimum parameters values. Measurements are obtained for various reaction times (0 - 45 min) temperatures (150 - 200 …

Visualizing Nutrient Effects On Root Pattern Formation, Robert E. Zdor
Faculty Publications
This lab gives students hands-on experience with visualizing the root architecture of plants exposed to varying concentrations of the vital nutrient phosphorus. By maintaining Brassica sp. seedlings in the presence of different quantities of phosphate, students can quantify changes in the number of lateral roots as an example of how the environment influences plant pattern formation. Additional variables in the experimental design, such as the use of plant mutants altered in plant regulator action or the presence of plant regulators in the plant growth medium, allow for exploration of how plant growth regulators are involved in root development. The quantitative …

© 2018 by the authors. Meat analogs are processed foods designed to mimic meat products. Their popularity is increasing among people seeking foods that are healthy and sustainable. Animal-sourced protein products differ in both their environmental impact and nutritional composition. The protein sources to produce meat analogs come from different plants. There is a lack of published research data assessing differences in these two aspects of meat analogs according to the plant protein source. This study compared the greenhouse gas (GHG) emissions of different types of meat analogs according to their main source of protein (wheat, soy, wheat and soy, …

1. Bald eagle (Haliaeetus leucocephalus) populations in North America rebounded in the latter part of the twentieth century, the result of tightened protection and outlawing of pesticides such as DDT. An unintended consequence of recovery may be a negative impact on seabirds. During the 1980s, few bald eagles disturbed a large glaucous‐winged gull (Larus glaucescens) colony on Protection Island, Washington, USA, in the Salish Sea. Breeding gull numbers in this colony rose nearly 50% during the 1980s and early 1990s. Beginning in the 1990s, a dramatic increase in bald eagle activity ensued within the colony, after which began a significant …

Understanding foraging ecology is an important element of effective conservation strategies. While West Indian manatees (Trichechus manatus) have been documented to consume a wide variety of vascular plants and algae, little is known about the diet of the Endangered Antillean subspecies (T. m. manatus) at freshwater sites such as the wetlands of Tabasco, the largest manatee habitat in Mexico. Here we present the results of a study of wild manatee diet in a freshwater site in Mexico. Controlled food choice experiments were conducted on a wild adult manatee during the dry seasons of 2011 and 2012. …

Carboxypeptidase O Is A Lipid Droplet-Associated Enzyme Able To Cleave Both Acidic And Polar C-Terminal Amino Acids, Linnea C. Burke, Hazel O. Ezeribe, Anna Y. Kwon, Donnell Dockery, Peter J. Lyons
Faculty Publications
Carboxypeptidase O (CPO) is a member of the M14 family of metallocarboxypeptidases with a preference for the cleavage of C-terminal acidic amino acids. CPO is largely expressed in the small intestine, although it has been detected in other tissues such as the brain and ovaries. CPO does not contain a prodomain, nor is it strongly regulated by pH, and hence appears to exist as a constitutively active enzyme. The goal of this study was to investigate the intracellular distribution and activity of CPO in order to predict physiological substrates and function. The distribution of CPO, when expressed in MDCK cells, …

Pathogens inflict a wide variety of disease manifestations on their hosts, yet the impacts of disease on the behaviour of infected hosts are rarely studied empirically and are seldom accounted for in mathematical models of transmission dynamics. We explored the potential impacts of one of the most common disease manifestations, fever, on a key determinant of pathogen transmission, host mobility, in residents of the Amazonian city of Iquitos, Peru. We did so by comparing two groups of febrile individuals (dengue-positive and dengue-negative) with an afebrile control group. A …

© 2016 Public Library of Science. All Rights Reserved. Background: Nearly half of the world’s population is at risk for dengue, yet no licensed vaccine or anti-viral drug is currently available. Dengue is caused by any of four dengue virus serotypes (DENV-1 through DENV-4), and infection by a DENV serotype is assumed to provide life-long protection against re-infection by that serotype. We investigated the validity of this fundamental assumption during a large dengue epidemic caused by DENV-2 in Iquitos, Peru, in 2010–2011, 15 years after the first outbreak of DENV-2 in the region. Methodology/Principal Findings: We estimated the age-dependent prevalence …

In 2010, an outbreak of febrile illness with arthralgic manifestations was detected at La Estación village, Portuguesa State, Venezuela. The etiologic agent was determined to be Mayaro virus (MAYV), a reemerging South American alphavirus. A total of 77 cases was reported and 19 were confirmed as seropositive. MAYV was isolated from acute-phase serum samples from 6 symptomatic patients. We sequenced 27 complete genomes representing the full spectrum of MAYV genetic diversity, which facilitated detection of a new genotype, designated N. Phylogenetic analysis of genomic sequences indicated that etiologic strains from Venezuela belong to genotype D. Results indicate that MAYV is …

It is currently unknown how important the Central American countries south of Belize are as a link between manatee populations in the north (Belize and Mexico) and populations in South America. Therefore, apart from knowing where manatees are found, it is important to understand how manatees are using these habitats and if they are moving between countries or distinct population centers. Here we report the results of a multi-national and multiinstitutional collaboration resulting in the first successful capture and satellite tracking of a West Indian manatee in southern Central America.

Egg Cannibalism In A Gull Colony Increases With Sea Surface Temperature, Lynelle M. Weldon, Shandelle M. Henson, James Hayward, Brianna G. Payne, Libby C. Megna, Andre E. Moncrieff
Faculty Publications
Cannibalism occurs regularly across a broad range of taxa with a variety of ecological and evolutionary consequences. Rises in sea surface temperature (SST) have been linked to increased cannibalism in some species, including polar bears (Ursus maritimus), Peruvian anchovy (Engraulis ringens), and Peruvian hake (Merluccius gayi peruanus), and might be expected in birds that depend on marine food webs for sustenance. Increased SSTs are associated with lowered ocean thermoclines and weakened upwellings. These changes, in turn, lead to decreased productivity in surface water and movement of surviving forage fish to deeper water, thereby food-stressing surface feeders such as gulls, diminishing …
