David Civitello co-authors a paper studying the effect of potassium enrichment on the growth and reproduction rate of a clone of Daphnia dentifera
Nutrient limitation commonly constrains organism growth and reproduction in natural ecosystems. Typically, ecologists focus on limitation introduced to systems by nitrogen and phosphorus. In a recent study, authors David Civitello, (USF Integrative Biology), Jessica Hite, (Indiana Univ., Bloomington, IN) Spencer Hall, (Indiana Univ., Bloomington, IN) focused on the limitations introduced by potassium on invertebrate consumers (Daphnia dentifera) and phytoplankton in freshwater lakes. All organisms require K for several metabolic processes. In a previous study linking K to disease, the authors found that K enrichment of water from one low-K lake stimulated the growth and reproduction of Daphnia. For their current study, they tested whether K could limit the production of Daphnia and phytoplankton across lakes and years and repeated a life table experiment using water collected from a low-K lake during a different year. K again stimulated Daphnia reproduction. They also enriched water from 12 lakes with K or P and measured short-term growth of Daphnia and the resident algal community. Read about their study here.
Leah Johnson co-authors paper on malaria control and the importance that senescence in the mosquito population plays in accounting for disease control
Malaria transmission studies widely use the assumption that mosquito mortality remains constant with age in making assessments of transmission risk, predictions of public health consequences, and the development of vector control strategies. Laboratory studies, on the other hand, provide clear evidence of mosquito senescence and decreased physiological function and increased vector mortality rate with age. Observation of these conditions in the wild have not proven practical. Authors Sadie Ryan, (Univ. of Florida, Gainesville, FL.), Tal Ben-Horin, (Univ. of Kwa-Zulu Natal, Durban, ZA) and Leah Johnson developed methods to integrate available field data to understand mortality in wild Anopheles gambiae, the most important vector of malaria in sub-Saharan Africa. They found evidence for an increase in rates of mortality with age. The authors also found that overall mortality is far greater in wild cohorts than commonly observed under protected laboratory conditions. Read more about their study here.
Rachel Taylor and Leah Johnson co-author study on the dynamics of crop-raiding baboons in a managed landscape
Protected parks have become an important tool in wildlife conservation, but these areas also provide for frequent occurrences of human-wildlife conflict at the edges of the parks as wildlife intrude on cultivated land at the park boundaries. Baboons take regular excursions outside parks to raid crop lands for food, causing conflict with human populations. Authors Rachel Taylor, (USF Integrative Biology), Sadie Ryan, (Univ. of Florida, Gainesville, FL.), Justin Brashares, (UC Berkeley, Berkeley, CA.) and Leah Johnson model the interactions of mesopredators (baboons), apex predators and shared prey in Greater Addo Elephant National Park in South Africa to analyze how four components affect the proportion of time that mesopredators choose to crop-raid.

Brad Gemmell co-authors paper on the development of multi-jet propulsion system in a colonial siphonophore
Physonect siphonophores are colonial cnidarians that are pervasive predators in many marine ecosystems. Physonects employ multiple, clonal medusan individuals, termed nectophores, to propel an aggregate colony. Authors John Costello, (Providence College, Providence, RI), Sean Colin, (Roger Williams Univ. Bristol, RI), Brad Gemmell, (USF Integrative Biology), John Dabiri, (Stanford Univ., Stanford, CA) and Kelly Sutherland (Univ. of Oregon, Eugene, OR) document that developmental differences between clonal nectophores of the physonect Nanomia bijuga produce a division of labor in thrust and torque production that controls direction and magnitude of the whole colony swimming, with smaller, less powerful young nectophores near the apex of the nectosome dominating torque production for turning, and older, larger, more powerful individuals near the base of the nectosome contributing predominantly to forward thrust production. Read about their interesting findings here.
Philipp Boersch-Supan co-authored paper on midwater shrimps of the South West Indian Ridge and a seamount off the Madagascar Ridge
Philipp Boersch-Supan, (USF Integrative Biology) co-authored a paper on midwater shrimps of the Indian Ridge with Tom Letessier, (Univ. of St. Andrew, Fife, UK), Sammy De Grave, (Oxford Natural History Museum, Oxford, UK), Kirsty Kemp, (Zoological Society of London, London, UK), Andrew Brierley, (Univ. of St. Andrew, Fife, UK) and Alex Rogers, (Univ. of Oxford, Oxford, UK) exploring factors inﬂuencing the distribution of epi- and meso-pelagic (0–1000 m) micronektonic crustaceans (>15 mm; order Lophogastridea, family Gnathophausiidea; and order Decapoda) on and off seamounts along the South West Indian Ridge (SWIR, 27° to 42°S) and on a seamount off the Madagascar Ridge (31.6°S, 42.8°E). Thirty-one species were found along the South West Indian Ridge but there was no latitude-related pattern in species richness. Instead enhanced biomass and species richness were found near seamounts which provide habitat for both mid-water and seabed-associated crustaceans. Read about their study here.
Elizabeth Roznik coauthors paper on how a natural disturbance in the environment reduced the risk of disease in an endangered rainforest frog population
Natural disturbances can drive disease dynamics in animal populations by altering the microclimate experienced by host and pathogen in a geographic area. Many pathogens are temperature and humidity sensitive, and small changes in either can increase or decrease their infectivity. Authors Elizabeth Roznik, (USF Integrative Biology), Sarah Sapsford, (Murdoch Univ., Murdoch, Western Australia), David Pike, Lin Schwarzkopf and Ross Alford (James Cook Univ., Townsville, Queensland, AU) published a paper showing that a reduction of rainforest canopy cover caused by a severe tropical cyclone in 2011 decreased the risk of endangered rainforest frogs (Litoria rheocola) becoming infected by the fungal pathogen (Batrachochytrium dendrobatidis).

Leah Johnson and Jason Rohr are awarded National Science Foundation (NSF) Ecology and Evolution of Infectious Diseases (EEID) grants
Emerging pandemic disease outbreaks such as Ebola increasingly threaten global health and world economies in today’s mobile society. Scientists expect five such new diseases to emerge and spread each year. A joint program between the National Science Foundation (NSF), National Institutes of Health (NIH) and the U.S. Department of Agriculture (USDA) is seeking answers to these outbreaks through the Ecology and Evolution of Infectious Diseases (EEID) program. Leah Johnson and Jason Rohr (USF Integrative Biology) were among the small group of recipients of awards this year. Leah is working on a US-UK collaborative research project titled “Vector Behavior in Transmission Ecology (VectorBiTE)", a study to “facilitate investigation into the role of vector behavior and life history in disease transmission dynamics". Jason is studying schistosomiasis, a neglected tropical disease (NTD) caused by a snail-transmitted trematode (flatworm), affects >240 million people worldwide, is devastating to children, and its effects are poverty reinforcing. He will study the effects of agrochemicals and mass drug administration campaigns on the disease. Read about their studies here.
Valerie (Jody) Harwood joins international team of scientists in study of the potential for infectious disease transmission from beach sand
Much attention is given to bacterial counts in water at bathing beaches, but recent studies suggest that beach sand can also serve as a vehicle for exposure of humans to pathogens at beaches. Valerie (Jody) Harwood joined a team of 28 other scientists in reviewing the literature on the subject of pathogen levels in beach sand and their potential for affecting human health. In their study, they outline published guidelines for beach monitoring programs, provide a background for spatial distribution of microbes and their temporal distribution in sand and make recommendations for a tiered approach monitoring.

Edward Haller co-authors paper on the development of somites in amphioxus and the implications of amphioxus somite development on the evolutionary theory of vertebrate somite development
Vertebrate somites are subdivided into lineage compartments, each with distinct cell fates and histories of origen. Insights into somite development can come from studying amphioxus, a primitive chordate. Amphioxus somites have myotome and non-myotome compartments, but their development and fates have not been completely described. During development, epithelial to mesenchymal transition is important for most vertebrate somitic lineages. Amphioxus somites have been thought to remain entirely epithelial. Authors Jennifer Mansfield, (Barnard College, Columbia University, New York, NY), Edward Haller, (USF Integrative Biology), Nicholas Holland, (Scripps Institution of Oceanography, University of California, San Diego, La Jolla, CA) and Ava Brent (Barnard College, Columbia University, New York, NY) examined amphioxus somites and derivatives, as well as extracellular matrix of the axial support system, in a series of developmental stages by transmission electron microscopy (TEM) and in situ hybridization for collagen expression. The use of extensive ultrastructural studies of various stages of development of amphioxus allow the authors to observe the fate of both somite cells and connective tissue during development with new clarity, allowing the authors to provide a revised model of development of the amphioxus sclerotome and fin boxes, and to confirm previous reports of development of the myotome and lateral somite.

David Civitello co-authors study on the dilution effect hypothesis for disease outbreaks
Authors Alexander Strauss, (Indiana University, Bloomington, IN), David Civitello, (USF Integrative Biology), Carla Cáceres, (University of Illinois at Urbana-Champaign, Urbana, IL) and Spencer Hall, (Indiana University, Bloomington, IN) point out that it remains challenging to predict variation in the magnitude of disease outbreaks. The dilution effect seeks to explain this variation by linking multiple host species to disease transmission. It predicts that disease risk increases for a focal host when host species diversity declines. However, when an increase in species diversity does not reduce disease, researchers are often unable to diagnose why. In their study, the authors investigate and describe the dilution effect with a general trait-based model of disease transmission in multi-host communities, using a multi-generational case study of a planktonic disease.

Jason Rohr co-authors study on restoring contaminated ecosystems
Chemical contamination has, and continues to, impair ecosystems, reducing biodiversity and the availability of natural resources. The abuse of resources has spurred a movement to restore contaminated ecosystems and develop and implement national and international regulations that require resource restoration. Restoration remains a young discipline that is still undergoing development. In a recently published paper, authors Jason Rohr, (USF Integrative Biology), Aïda Farag, (U. S. Geological Survey, Jackson, WY), Marc Cadotte, (Univ. of Toronto-Scarborough, Scarborough, ON), William Clements, (Colorado State Univ., Fort Collins, CO), James Smith, (Indiana Dept. Environmental Management, Indianapolis, IN), Cheryl Ulrich, (Dewberry, Inc., Jacksonville, FL), and Richard Woods, (ExxonMobil Biomedical Sciences, Inc., Annadale, NJ) provide guidance to scientists and practitioners on when, where, and how to restore contaminated ecosystems.

Christy Foust, Aaron Schrey and Christina Richards co-author chapter on epigenetics in book on plant nuclear biology
Population genetics examines the extent of genetic variation and changes to genetic variation, in response to evolutionary processes that may cause changes in populations. The Modern Synthesis (MS), states that evolutionary change is often equated with genetic divergence, and phenotypic variation is solely dependent on the emergence of random sequence mutations in the germ line. Epigenetic inheritance is a form of variation not addressed by the Modern Synthesis. In their chapter in the book Nuclear Functions in Plant Transcription, Signaling and Development, authors Christy Foust, Aaron Schrey and Christina Richards discuss population epigenetics and the importance of epigenetics research and theory in understanding inheritance and variation.

Stephanie Gervasi, David Civitello, Holly Kilvitis and Lynn (Marty) Martin publish paper on role of plasticity in host-parasite dynamics in infection
Predicting the disease risk to humans, domestic animals and wildlife has become more crucial as the frequency and severity of emergent events continues to increase. Host abundance strongly influences whether a parasite will establish in an area. Host competence, the proficiency with which a host transmits a parasite to another host or vector is also becoming an apparent important factor in the equation of infection dynamics. Competence is governed not only by genetic variation of hosts, parasites, or vectors but also by the environment in which such genetic variants occur. Authors Stephanie Gervasi, David Civitello, Holly Kilvitis, and Lynn (Marty) Martin, (USF Integrative Biology) focused on phenotypic plasticity as a mediator of variation in host competence and environmentally dependent disease risk. The authors argue that variation in phenotypic plasticity among and within species strongly contributes to epidemiological dynamics when parasites are shared among multiple hosts, which is often the case.

Valerie (Jody) Harwood and Bina Nayak co-author paper on novel microarray for pathogen detection and fecal source identification in environmental systems
It is difficult to detect and identify pathogens and fecal contamination in environmental waters. Pathogen diversity and presence of fecal indicator bacteria in the natural environment complicate the assessment of risk and hamper remediation efforts. Authors Xiang Li, (West Virginia Univ., Morgantown, WV), Valerie (Jody) Harwood, (USF Integrative Biology), Bina Nayak, (USF Integrative Biology), Christopher Staley, (Univ. of Minnesota, St. Paul, MN), Michael Sadowsky, (Univ. of Minnesota, St. Paul, MN) and Jennifer Weidhaas, (West Virginia Univ., Morgantown, WV) tested a custom microarray targeting pathogens (viruses, bacteria, protozoa), microbial source tracking (MST) markers, and antibiotic resistance genes against DNA obtained from whole genome amplification (WGA) of RNA and DNA from sewage and animal (avian, cattle, poultry and swine) feces. The purpose of their study was to design and validate an MST microarray for detecting fecal contamination and pathogens in environmental samples, while simultaneously indicating the source of fecal contamination. Further studies were conducted to evaluate the correlation between the microarray fluorescence and more established methods (qPCR and culture based methods). Finally, next generation sequencing was conducted by the authors to determine the relative coverage of the fecal microbiome represented by the microarray-based probes.

Marta Robertson and Christina Richards write mini-review on the importance of plant studies in evolutionary theory of non-genetic inheritance
In the Modern Synthesis (MS), evolutionary change is often equated with genetic divergence, and phenotypic variation is solely dependent on the emergence of random sequence mutations in the germ line. Current research, however, shows that this simplistic view does not incorporate roles that are played by interaction of individuals with their environment, and the effect of disease and need of adaptation with time. Epigenetic phenomenon, therefore, come into play. Authors Marta Robertson and Christina Richards, (USF Integrative Biology), wrote a mini-review on epigenetics, presenting evidence for a role of epigenetic mechanisms in the evolutionary process and discuss common objections to incorporating epigenetics into evolutionary theory. This review is not exhaustive, but is meant to demonstrate that epigenetic inheritance can be incorporated into current evolutionary theory without overhauling its foundations.

David Civitello co-authors a paper combining mesocosm and field experiments to predict invasive plant performance
Invasive plant fecundity is at the heart of propagule pressure and ultimately determines range expansion. Predicting plant fecundity across large spatial scales, regions and landscapes, is critical in weed management. In order to accurately predict fecundity, improved models that scale individual plant performance across various environments need to be developed. Authors Chris Wilson, (Univ. of Florida, Gainesville, FL), T. Trevor Caughlin, (Univ. of Florida, Gainesville, FL), David Civitello, (USF Integrative Biology), and S. Luke Flory, (Univ. of Florida, Gainesville, FL) combined two experimental data sets to predict fecundity of a widespread and problematic invasive grass, Japanese stiltgrass, (Microstegium vimineum), over large spatial scales. The authors analyzed seed production as a function of plant biomass while while manipulating light levels in a field experiment, then conducted controlled field introduction experiments in various plots differing in available light and other factors.

Neal Halstead, David Civitello and Jason Rohr co-author paper comparing toxicity of organophosphate and pyrethroid insecticides on aquatic macroarthropods
Agricultural expansion and intensification has brought with it increased use of insecticides globally. Insecticide runoff poses a particular threat to aquatic macroarthropods such as the crayﬁsh, Procambarus alleni and the water bug, Belostoma ﬂumineum. Authors Neal Halstead, David Civitello and Jason Rohr, (USF Integrative Biology) exposed these two common macroarthropod predators to three insecticides in each of two insecticide classes (three organophosphates and three pyrethroids) to assess their toxicities. They generated 150 simulated environmental exposures and monitored animal response. Read about the findings of their study here.

Bina Nayak and Valerie (Jody) Harwood co-author paper on correlation of LA35 poultry fecal marker persistence with that of indicators and pathogens in environmental waters
Bina Nayak, (USF Integrative Biology), Jennifer Weidhaas, (West Virginia Univ., Morgantown, WV), and Valerie (Jody) Harwood, (USF Integrative Biology) conducted a microbial source tracking (MST) study comparing the persistence of the Brevibacterium sp. LA35 16S rRNA gene (marker) for poultry litter with that of pathogens and FIB under outdoor, environmentally relevant conditions in fresh and marine water and sediments over seven days. Disposal of fecal-contaminated poultry litter by applying the litter to soil can result in pathogens and fecal indicator bacteria flushing into receiving waters via runoff. The authors monitored LA35, pathogens and FIB in water samples and sediment during the seven day time period. LA35 levels correlated well with other bacteria in the water column, but not in sediments. Read more about their research here.

Amber Ferguson, Marc Lajeunesse and Philip Motta publish study on feeding performance of king mackerel
Feeding performance is the ability of a predator to capture and handle prey. Although bite force is a commonly used metric for measuring feeding performance, other factors such as bite pressure and strike speed affect the ability to capture prey. Authors Amber Ferguson, (USF IB graduate, MS, 2014), Daniel Huber, (Univ. of Tampa, Tampa, FL), Marc Lajeunesse, (USF Integrative Biology), and Philip Motta, (USF Integrative Biology) conducted a study to investigate static bite force, dynamic speeds, and predator and prey forces resulting from ram strikes, as well as bite pressure of the king mackerel, Scomberomorus cavalla, in order to examine their relative contributions to overall feeding performance. Their study suggests that king mackerel rely on high velocity chases and high bite pressure generated via sharp, laterally compressed teeth to maximize feeding performance.
