John David N. Dionisio
GRNsight is a web application and service for visualizing models of gene regulatory networks (GRNs). A gene regulatory network (GRN) consists of genes, transcription factors, and the regulatory connections between them which govern the level of expression of mRNA and protein from genes. The original motivation came from our efforts to perform parameter estimation and forward simulation of the dynamics of a differential equations model of a small GRN with 21 nodes and 31 edges. We wanted a quick and easy way to visualize the weight parameters from the model which represent the direction and magnitude of the influence of …

Histology And Ultrastructure Of Montastraea Cavernosa And Porites Astreiodes During Regeneration And Recruitment: Anthropogenic Stressors And Transplant Success, Dorothy-Ellen A. Renegar
Histology And Ultrastructure Of Montastraea Cavernosa And Porites Astreiodes During Regeneration And Recruitment: Anthropogenic Stressors And Transplant Success, Dorothy-Ellen A. Renegar
D. Abigail Renegar
Corals combine photosynthesis and calcification in an intricate and delicately balanced relationship to form large biomineralized structures that are dominant features of tropical coastlines worldwide. Coral reefs have great scientific and economic importance but have recently experienced widespread decline attributed to increasing anthropogenic pressure on reef systems. Physical damage events, such as ship groundings, when coupled with existing nutrient stress and changing global climate present a poor outlook for successful natural recovery of reef communities. The main goal of the proposed research is to better understand how environmental factors, both local and global, affect the coral holobiont and influence overall …
Reproductive Parameters Of Coastal Pelagic Fishes, Sonia Ahrabi-Nejad, David W. Kerstetter, Patricia Blackwelder, Dorothy-Ellen A. Renegar
Reproductive Parameters Of Coastal Pelagic Fishes, Sonia Ahrabi-Nejad, David W. Kerstetter, Patricia Blackwelder, Dorothy-Ellen A. Renegar
D. Abigail Renegar
The ability to manage a fish stock relies on an understanding of life history characteristics and basic biology of the species. Numerous age-growth studies are facilitated by the relative ease of ageing fishes through hard-part analyses. Determining reproductive parameters for fish populations is just as important for stock assessments and management, and histological examination of gonads provides the most accurate determination of fecundity and spawning periods. However, research in this area is limited. Coastal pelagic fishes are often targeted commercially and recreationally due to their easy access by private vessels. The objective of this study is to provide baseline data …
Ultrastructural And Histological Analysis Of Dark Spot Syndrome In Siderastrea Siderea And Agaricia Agaricites, Dorothy-Ellen A. Renegar, Patricia Blackwelder, J. D. Miller, D. J. Gochfeld, Alison L. Moulding
Ultrastructural And Histological Analysis Of Dark Spot Syndrome In Siderastrea Siderea And Agaricia Agaricites, Dorothy-Ellen A. Renegar, Patricia Blackwelder, J. D. Miller, D. J. Gochfeld, Alison L. Moulding
D. Abigail Renegar
Dark Spot Syndrome (DSS) typically manifests in scleractinian corals as lesions of varying color, size, shape and location that can result in skeletal changes and tissue death. A causative agent for DSS has not yet been identified. The objective of this study was histological and ultrastructural comparison of the cellular and skeletal characteristics of DSS-affected and healthy Siderastrea siderea and Agaricia agaricites. The greater resolution possible with transmission electron microscopy (TEM) revealed microbial activity and tissue changes not resolvable utilizing histology. DSS-affected tissue had less integrity, with increasing cellular degradation and vacuolization. A high concentration of electron dense inclusions, …
Effect Of Nutrient Enrichment And Elevated Co2 Partial Pressure On Growth Rate Of The Zooxanthellate Coral Acropora Cervicornis., Dorothy-Ellen A. Renegar
Effect Of Nutrient Enrichment And Elevated Co2 Partial Pressure On Growth Rate Of The Zooxanthellate Coral Acropora Cervicornis., Dorothy-Ellen A. Renegar
D. Abigail Renegar
Trends of increasing coastal eutrophication and atmospheric pCO2 require investigation to predict the combined effects on coral and reef condition and growth. Increases in nutrient concentrations have been observed over the past several decades in a number of reef systems, and it has been predicted that this will adversely affect coral growth rates. The species targeted by this research, Acropora cervicornis, is among the most important reef-builders in the Caribbean and has suffered widespread mortality in southern Florida. Approximately 192 branch tips were harvested from two local populations of A. cervicornis and maintained in the laboratory, where the growth rate …
Coral Ultrastructural Response To Elevated Pco2 And Nutrients During Tissue Repair And Regeneration, Dorothy-Ellen A. Renegar, Patricia Blackwelder, Alison L. Moulding
Coral Ultrastructural Response To Elevated Pco2 And Nutrients During Tissue Repair And Regeneration, Dorothy-Ellen A. Renegar, Patricia Blackwelder, Alison L. Moulding
D. Abigail Renegar
Corals and coral reefs have recently experienced widespread decline attributed to anthropogenic pressure on reef systems. Studies have demonstrated that nutrient and pCO2 stress effect coral growth and calcification, but study of specific effects on coral tissue is lacking. The objective of this research was to examine wound healing in corals and how it is affected by exposure to elevated nutrients and pCO2. Coral tissue repair and regeneration during wound healing in Montastraea cavernosa and Porites astreoides were assessed histologically and ultrastructurally by examining colony fragments exposed to elevated nitrate, phosphate, and pCO2. In M. cavernosa, tissue repair was facilitated …
Acute And Sub-Acute Toxicity Of The Polycyclic Aromatic Hydrocarbon 1-Methylnaphthalene To The Shallow-Water Coral Porites Divaricata: Application Of A Novel Exposure Protocol, Dorothy-Ellen A. Renegar, Nick Turner, Bernhard Riegl, Richard E. Dodge, Anthony H. Knap, Paul Schuler
Acute And Sub-Acute Toxicity Of The Polycyclic Aromatic Hydrocarbon 1-Methylnaphthalene To The Shallow-Water Coral Porites Divaricata: Application Of A Novel Exposure Protocol, Dorothy-Ellen A. Renegar, Nick Turner, Bernhard Riegl, Richard E. Dodge, Anthony H. Knap, Paul Schuler
D. Abigail Renegar
Previous research evaluating hydrocarbon toxicity to corals and coral reefs has generally focused on community-level effects, and results often are not comparable between studies because of variability in hydrocarbon exposure characterization and evaluation of coral health and mortality during exposure. Toxicity of the polycyclic aromatic hydrocarbon 1-methylnaphthalene to the coral Porites divaricata was assessed in a constant exposure toxicity test utilizing a novel toxicity testing protocol uniquely applicable to shallow-water corals, which considered multiple assessment metrics and evaluated the potential for post-exposure mortality and/or recovery. Acute and subacute effects (gross morphological changes, photosynthetic efficiency, mortality, and histologic cellular changes) were …
Pharmacological Validation Of An Inward-Rectifier Potassium (Kir) Channel As An Insecticide Target In The Yellow Fever Mosquito Aedes Aegypti, Matthew F. Rouhier, Rene Raphemot, Jerod S. Denton, Peter M. Piermarini
Pharmacological Validation Of An Inward-Rectifier Potassium (Kir) Channel As An Insecticide Target In The Yellow Fever Mosquito Aedes Aegypti, Matthew F. Rouhier, Rene Raphemot, Jerod S. Denton, Peter M. Piermarini
Matthew F Rouhier
Mosquitoes are important disease vectors that transmit a wide variety of pathogens to humans, including those that cause malaria and dengue fever. Insecticides have traditionally been deployed to control populations of disease-causing mosquitoes, but the emergence of insecticide resistance has severely limited the number of active compounds that are used against mosquitoes. Thus, to improve the control of resistant mosquitoes there is a need to identify new insecticide targets and active compounds for insecticide development. Recently we demonstrated that inward rectifier potassium (Kir) channels and small molecule inhibitors of Kir channels offer promising new molecular targets and active compounds, respectively, …

Matthew F Rouhier
Vector-borne diseases such as dengue fever and malaria, which are transmitted by infected female mosquitoes, affect nearly half of the world's population. The emergence of insecticide-resistant mosquito populations is reducing the effectiveness of conventional insecticides and threatening current vector control strategies, which has created an urgent need to identify new molecular targets against which novel classes of insecticides can be developed. We previously demonstrated that small molecule inhibitors of mammalian Kir channels represent promising chemicals for new mosquitocide development. In this study, high-throughput screening of approximately 30,000 chemically diverse small-molecules was employed to discover potent and selective inhibitors of Aedes …
Eliciting Renal Failure In Mosquitoes With A Small-Molecule Inhibitor Of Inward-Rectifying Potassium Channels, Matthew F. Rouhier, Rene Raphemot, Corey R. Hopkins, Rocco D. Gogliotti, Kimberly M.

Matthew F Rouhier
Mosquito-borne diseases such as malaria and dengue fever take a large toll on global health. The primary chemical agents used for controlling mosquitoes are insecticides that target the nervous system. However, the emergence of resistance in mosquito populations is reducing the efficacy of available insecticides. The development of new insecticides is therefore urgent. Here we show that VU573, a small-molecule inhibitor of mammalian inward-rectifying potassium (Kir) channels, inhibits a Kir channel cloned from the renal (Malpighian) tubules of Aedes aegypti (AeKir1). Injection of VU573 into the hemolymph of adult female mosquitoes (Ae. aegypti) disrupts the production and excretion of urine …
Non-Human Primates In Neuroscience Research: The Case Against Its Scientific Necessity, Jarrod Bailey, Katy Taylor
Non-Human Primates In Neuroscience Research: The Case Against Its Scientific Necessity, Jarrod Bailey, Katy Taylor
Jarrod Bailey, PhD
Public opposition to non-human primate (NHP) experiments is significant, yet those who defend them cite minimal harm to NHPs and substantial human benefit. Here we review these claims of benefit, specifically in neuroscience, and show that: a) there is a default assumption of their human relevance and benefit, rather than robust evidence; b) their human relevance and essential contribution and necessity are wholly overstated; c) the contribution and capacity of non-animal investigative methods are greatly understated; and d) confounding issues, such as species differences and the effects of stress and anaesthesia, are usually overlooked. This is the case in NHP …
An Assessment Of The Role Of Chimpanzees In Aids Vaccine Research, Jarrod Bailey
An Assessment Of The Role Of Chimpanzees In Aids Vaccine Research, Jarrod Bailey
Jarrod Bailey, PhD
Prior to Simian Immunodeficiency Virus (SIV)-infected macaques becoming the ‘model of choice’ in the 1990s, chimpanzees were widely used in AIDS vaccine research and testing. Faced with the continued failure to develop an effective human vaccine, some scientists are calling for a return to their widespread use. To assess the past and potential future contribution of chimpanzees to AIDS vaccine development, databases and published literature were systematically searched to compare the results of AIDS vaccine trials in chimpanzees with those of human clinical trials, and to determine whether the chimpanzee trials were predictive of the human response. Protective and/or therapeutic …
The Other Side Of Silence: Rachel Carson’S Views Of Animals, Marc Bekoff, Jan Nystrom
The Other Side Of Silence: Rachel Carson’S Views Of Animals, Marc Bekoff, Jan Nystrom
Marc Bekoff, PhD
The publication of Rachel Carson’s Silent Spring in 1962 is widely regarded as one of the major events that launched the modern environmental movement. Silent Spring is a compelling blend of stories, natural history, human values, and biological facts. In this essay we consider Carson’s attitude toward animals in Silent Spring and in other texts. Despite the facts that she was raised to love Nature and animals, little direct attention has been given to Carson’s views about our moral responsibilities to, and the moral standing of animals. Carson favored responsible stewardship, was more of an animal welfarist and environmentalist/conservation biologist …
Compassion As A Practical And Evolved Ethic For Conservation, David Ramp, Marc Bekoff
Compassion As A Practical And Evolved Ethic For Conservation, David Ramp, Marc Bekoff
Marc Bekoff, PhD
The ethical position underpinning decisionmaking is an important concern for conservation biologists when setting priorities for interventions. The recent debate on how best to protect nature has centered on contrasting intrinsic and aesthetic values against utilitarian and economic values, driven by an inevitable global rise in conservation conflicts. These discussions have primarily been targeted at species and ecosystems for success, without explicitly expressing concern for the intrinsic value and welfare of individual animals. In part, this is because animal welfare has historically been thought of as an impediment to conservation. However, practical implementations of conservation that provide good welfare outcomes …
Rapid Recovery Of A Coral Reef At Darwin Island, Galapagos Island, Peter W. Glynn, Bernhard Riegl, Adrienne M. S. Correa, Iliana B. Baums
Rapid Recovery Of A Coral Reef At Darwin Island, Galapagos Island, Peter W. Glynn, Bernhard Riegl, Adrienne M. S. Correa, Iliana B. Baums
Bernhard Riegl
Surveys at Darwin Island in 2006 and 2007 have demonstrated that this northernmost Galapagos Islands coral reef has recovered significantly since the 1982-3 El Nino event. When first surveyed in 1975, this structural reef exhibited actively accreting frameworks of pocilloporid and poritid corals. The coral suffered severe mortality in 1983, resulting in the near total loss of pocilloporids and extensive partial mortality of poritid corals. Large sections of the reef had not recovered by 1992 and dead frameworks were subject to bio-erosion, although small numbers of sexual recruits of pocilloporid corals and numerous recruits plus regenerating patches of Porites lobata …
Environmental Impacts Of Dredging And Other Sediment Disturbances On Corals: A Review, Paul. L. A. Erftemeijer, Bernhard Riegl, Bert W. Hoeksema, Peter A. Todd
Environmental Impacts Of Dredging And Other Sediment Disturbances On Corals: A Review, Paul. L. A. Erftemeijer, Bernhard Riegl, Bert W. Hoeksema, Peter A. Todd
Bernhard Riegl
A review of published literature on the sensitivity of corals to turbidity and sedimentation is presented, with an emphasis on the effects of dredging. The risks and severity of impact from dredging (and other sediment disturbances) on corals are primarily related to the intensity, duration and frequency of exposure to increased turbidity and sedimentation. The sensitivity of a coral reef to dredging impacts and its ability to recover depend on the antecedent ecological conditions of the reef, its resilience and the ambient conditions normally experienced. Effects of sediment stress have so far been investigated in 89 coral species (∼10% of …
Prototype For Monitoring And Forecasting Fall Foliage Coloration In Real Time From Satellite Data, Xiaoyang Zhang, Mitchell D. Goldberg, Yunyue Yu
Prototype For Monitoring And Forecasting Fall Foliage Coloration In Real Time From Satellite Data, Xiaoyang Zhang, Mitchell D. Goldberg, Yunyue Yu
Xiaoyang Zhang
While determining vegetation phenology from the time series of historical satellite data has been widely investigated throughout the last decade, little effort has been devoted to real-time monitoring and short-term forecasting. The latter is more important for numerical weather modeling, ecosystem forecasting, forest and crop management, and health risk warning. In this study we developed a prototype approach for the real-time monitoring and short-term forecasting of fall foliage status (including low coloration, moderate coloration, near-peak coloration, peak coloration, and post-peak coloration) using temporal satellite observations. The algorithm combined the climatology of vegetation phenology and temporally available satellite observations to establish …
Estimation Of Crop Gross Primary Production (Gpp): Ii. Do Scaled Modis Vegetation Indices Improve Performance?, Qingyuan Zhang, Yen-Ben Cheng, Alexei I. Lyapustin, Yujie Wang, Xiaoyang Zhang, Andrew Suyker, Shashi Verma, Yanmin Shuai, Elizabeth M. Middleton
Estimation Of Crop Gross Primary Production (Gpp): Ii. Do Scaled Modis Vegetation Indices Improve Performance?, Qingyuan Zhang, Yen-Ben Cheng, Alexei I. Lyapustin, Yujie Wang, Xiaoyang Zhang, Andrew Suyker, Shashi Verma, Yanmin Shuai, Elizabeth M. Middleton
Xiaoyang Zhang
Satellite remote sensing estimates of gross primary production (GPP) have routinely been made using spectral vegetation indices (VIs) over the past two decades. The Normalized Difference Vegetation Index (NDVI), the Enhanced Vegetation Index (EVI), the green band Wide Dynamic Range Vegetation Index (WDRVIgreen), and the green band Chlorophyll Index (CIgreen) have been employed to estimate GPP under the assumption that GPP is proportional to the product of VI and photosynthetically active radiation (PAR) (where VI is one of four VIs: NDVI, EVI, WDRVIgreen, or CIgreen). However, the empirical regressions between VI*PAR and …
Ignoring Nature: Why We Do It, The Dire Consequences, And The Need For A Paradigm Shift To Save Animals, Habitats, And Ourselves, Marc Bekoff, Sarah Bexell

Marc Bekoff, PhD
The article discusses the importance of biodiversity and on how people protect animals and habitats. It describes the conservation psychology and conservation social work. It suggests that there will be fewer people who will actually be able to make a positive difference in the relationships with animals and ecosystems.
Mapping Temperate Vegetation Climate Adaptation Variability Using Normalized Land Surface Phenology, Liang Liang, Mark D. Schwartz, Xiaoyang Zhang
Mapping Temperate Vegetation Climate Adaptation Variability Using Normalized Land Surface Phenology, Liang Liang, Mark D. Schwartz, Xiaoyang Zhang
Xiaoyang Zhang
Climate influences geographic differences of vegetation phenology through both contemporary and historical variability. The latter effect is embodied in vegetation heterogeneity underlain by spatially varied genotype and species compositions tied to climatic adaptation. Such long-term climatic effects are difficult to map and therefore often neglected in evaluating spatially explicit phenological responses to climate change. In this study we demonstrate a way to indirectly infer the portion of land surface phenology variation that is potentially contributed by underlying genotypic differences across space. The method undertaken normalized remotely sensed vegetation start-of-season (or greenup onset) with a cloned plants-based phenological model. As the …

Probing The Past 30-Year Phenology Trend Of Us Deciduous Forests, X. Yue, N. Unger, Xiaoyang Zhang, C.S. Vogel
Xiaoyang Zhang
Phenology is experiencing dramatic changes over deciduous forests in the USA. Estimates of trends in phenology on the continental scale are uncertain, however, with studies failing to agree on both the magnitude and spatial distribution of trends in spring and autumn. This is due to the sparsity of in situ records, uncertainties associated with remote sensing data, and the regional focus of many studies. It has been suggested that reported trends are a result of recent temperature changes, though multiple processes are thought to be involved and the nature of the temperature forcing remains unknown. To date, no study has …

Characterization Of Ceriporiopsis Subvermispora Bicupin Oxalate Oxidase Expressed In Pichia Pastoris, Patricia Moussatche, Alexander Angerhofer, Witcha Imaram, Eric Hoffer, Kelsey Uberto, Christopher Brooks, Crystal Bruce, Daniel Sledge, Nigel G. J. Richards, Ellen W. Moomaw
Ellen Moomaw
Oxalate oxidase (E.C. 1.2.3.4) catalyzes the oxygen-dependent oxidation of oxalate to carbon dioxide in a reaction that is coupled with the formation of hydrogen peroxide. Although there is currently no structural information available for oxalate oxidase fromCeriporiopsis subvermispora (CsOxOx), sequence data and homology modeling indicate that it is the first manganese-containing bicupin enzyme identified that catalyzes this reaction. Interestingly, CsOxOx shares greatest sequence homology with bicupin microbial oxalate decarboxylases (OxDC). We show that CsOxOx activity directly correlates with Mn content and other metals do not appear to be able to support catalysis. EPR spectra indicate that the Mn is present …
Institutional Animal Care And Use Committees: A Flawed Paradigm Or Work In Progress?, John P. Gluck, F. Barbara Orlans
Institutional Animal Care And Use Committees: A Flawed Paradigm Or Work In Progress?, John P. Gluck, F. Barbara Orlans
John P. Gluck, PhD
In his challenging article, Steneck (1997) criticized the creation of the Institutional Animal Care and Use Committee (IACUC) system established by the 1985 amendments to the Animal Welfare Act. He saw the IACUC review and approval of biomedical and behavioral research with animals as an unnecessary "reassignment" of duties from existing animal care programs to IACUC committees. He argued that the committees are unable to do the work expected of them for basically three reasons: (a) the membership lacks the expertise in matters relevant to animal research and care, (b) there exists an inherent and disabling conflict of interest, and …

Fallout Pu In Annual Bands From The Coral Montastrea Annularis, St. Croix, Usvi, Larry K. Benninger, Richard E. Dodge
Richard Dodge
Coralline aragonite is known to incorporate certain minor or trace constituents from seawater (U, Sr, Ra, 210Pb) with essentially constant discrimination relative to Ca. Noshkin and others [Limnol. Oceanogr. 20(1975)729] reported that Pu was also incorporated with constant discrimination and suggested the use of annual bands in corals as a recording indicator of ambient seawater Pu. We report preliminary results of a study of fallout Pu in annual bands of Montastrea annularis from St. Croix, U.S.V.I. Along with fallout Pu we have determined: U, 232Th, 228Ra (as 228Th) and 210Pb (as 210Po). These determinations are used to test for constancy …
