Reassignment Of Some Caryospora Species (Apicomplexa: Eimeriidae) To Eumonospora (Apicomplexa: Sarcocystidae) And A Summary, Donald W. Duszynski

MANTER: Journal of Parasite Biodiversity

This review was crafted to clear up some of the current confusion regarding the correct taxonomic placement of those apicomplexan coccidians that produce unique monosporocystic octosporozoic (1 sporocyst with 8 sporozoites) oocysts during the sexual phase of their life history in vertebrate hosts. Currently, such oocysts have been placed in 1 of 4 genera, Avispora, Caryospora, Karyospora, or Eumonospora, 2 of which are no longer accepted or useful (Avispora and Karyospora). My review suggests that to present (2023) there are 62 valid Caryospora and 26 valid Eumonospora species. Caryospora species are recorded from a bird …

An Examination Of The Eastern Nebraska And Western Iowa Flash Flood Event Of 6-7 August 1999, Catherine M. Zapotocny

NOAA Technical Reports and Related Materials

Flash flooding occurs each summer in eastern Nebraska and western Iowa. While 10-inch rains are extraordinary, it is not uncommon to have at least one excessive rain event during the annual convective season. A significant flash flood occurred in east central Nebraska and western Iowa the night of August 6, 1999 into the morning of August 7, 1999. Antecedent hydrologic conditions limited the loss of life, however considerable property damage resulted as the heavy rain fell over the urbanized areas in eastern Nebraska and western Iowa.

Several flash flood ingredients came together over the area. These meteorological factors are typical …

A Dietary Variety: Analyzing The Impacts Of Diverse Vs Worm-Exclusive Diets On The Blanding’S Turtle (Emydoidea Blandingii), Caitlin F. Copenhaver

Honors Theses

The endangered Blanding’s turtle (Emydoidea blandingii) is a species with a generally diverse diet in their freshwater wetland habitats; they consume prey such as crayfish and snails. In captivity, these options often become more limited due to logistical reasons. As ex situ conservation efforts such as captive rearing and head-starting are becoming more popular for this species, it will be important to gain more insight on how these more limited diets might affect these turtles. This study describes a comparison between diets in six captive Blanding’s turtles from September to November of 2023, with three turtles receiving only …

Resolution Of The Tetrabothrius Jagerskioeldi Cryptic Species Complex Among Holarctic Alcidae (Charadriiformes): Cestodes Among Fraterculinae—Exploring Marine Diversity, Host Range, And Dynamic Oceanography In The Greater North Pacific, Eric P. Hoberg, Kaylen Marie Soudachanh, Svetlana K. Bondarenko

MANTER: Journal of Parasite Biodiversity

In the biosphere, limits for diversity among species, communities, and biomes are revealed through intensive and extensive field-based inventory and assembly of voucher specimens and associated informatics examined in a phylogenetic, historical, ecological, and biogeographic arena. Archival resources for specimens and information contribute to a cumulative view of faunal structure and assembly under a comparative umbrella. Ultimately, species definitions, and inclusive partitions among populations and lineages, are fundamental in articulating hypotheses that examine interactions about evolution, the nature of organisms, and the condition of environments across space and time. We conclude our proposals establishing species limits for tapeworms of the …

D-Shaped Nematode Eggs In The Feces Of Rangifer Tarandus: A Story In Pictures, Olga A. Loginova

MANTER: Journal of Parasite Biodiversity

D-shaped nematode eggs in the feces of Rangifer tarandus are expected to be oxyurid nematodes (Nemata: Oxyurida) of the genus Skrjabinema. The species S. tarandi is considered species-specific for this host. There is no consensus regarding the cross-infection of reindeer and sheep with S. ovis and S. tarandi. The drawings proposed by descriptors complicate differential diagnostics. Micrographs of S. tarandi eggs obtained via light microscopy and scanning electron microscopy as well as photographs of S. ovis eggs and drawings made on their basis are proposed to confidently distinguish between representatives of these two species, taking into account morphometric data. Thus, …

2023 Coordinated Spring Survey Of Mid-Continent Sandhill Cranes, Terry Liddick

United States Fish and Wildlife: Staff Publications

The aerial transect portion of the coordinated spring survey of mid-continent Sandhill cranes was conducted on March 22, 2023 in Nebraska’s Central Platte and North Platte River valleys (United States). The 2023 photo-corrected aerial estimate is 1,259,000 birds. Outside the traditional aerial transect portion, observers conducted ground surveys during the period March 20–22. From these regions, observers in the Official Survey Area (OSA) of Nebraska, Kansas, Texas, Oklahoma, and Wyoming reported an additional 25,363 cranes. The 2023 total estimate (1,284,500) increased 43.1% from 2022. The current three-year average (2021–2023 with no photo correction in 2021), based on photo corrected estimates …

Preliminary Evidence Of Anticoagulant Rodenticide Exposure In American Kestrels (Falco Sparverius) In The Western United States, Evan R. Buechley, Dave Oleyar, Jesse L. Watson, Jennifer Bridgeman, Steven Volker, David A. Goldade, Catherine E. Swift, Barnett A. Rattner

United States Geological Survey: Staff Publications

Although there is extensive evidence of declines in the American Kestrel (Falco sparverius) population across North America, the cause of such declines remains a mystery. One hypothesized driver of decline is anticoagulant rodenticide (AR) exposure, which could potentially cause mortality or reduced fitness. We investigated AR exposure in wild American Kestrels in Utah, USA. We collected and tested for AR residues in liver samples (n = 8) from kestrels opportunistically encountered dead and in blood samples (n = 71) from live wild kestrels, both nestlings and adults. We found high detection rates in both tissues. Adult …

Helminth Parasites Of The Giant Toad, Rhinella Horribilis (Wiegmann, 1833) (Anura: Bufonidae) From Central Mexico, Jorge Falcón-Ordaz, Cristian Raúl Olvera-Olvera, Marisol Moreno-Chávez, Griselda Pulido-Flores, Scott Monks, Luis García-Prieto

MANTER: Journal of Parasite Biodiversity

As part of an ongoing project to inventory the helminth parasites of amphibians from the state of Hidalgo, Central Mexico, specimens of Rhinella horribilis were collected from three municipalities: Eloxochitlán, Huehuetla, and San Felipe Orizatlán. A total of eight taxa of helminths were found: three digeneans (Haematoloechus sp., Langeronia macrocirra, and Mesocoelium danforthi) and five nematodes (Cosmocerca sp., Cruzia morleyi, Ochoterenella chiapensis, Oswaldocruzia subauricularis, and Rhabdias sp.). The highest species richness was recorded in Huehuetla. All reports of these species of helminths represent new locality records for Mexico.

A Diverse Flea (Siphonaptera) Assemblage From The Small Mammals Of Central New Mexico, Dianne E. Peterson, Jonathan L. Dunnum, Schuyler W. Liphart, Karen A. Boegler, Ralph P. Eckerlin, Eric P. Hoberg, Martha O. Perez-Arriaga, Katrina Derieg, David Garnand, Mariel L. Campbell, Joseph A. Cook

MANTER: Journal of Parasite Biodiversity

The geographical ranges of many mammals and their associated parasites are dynamic. Comprehensive documentation of these communities over time provides a foundation for interpreting how changing environmental conditions, driven by accelerating climate change, other anthropogenic disturbances, and natural events, may influence host-parasite interactions. Fleas (Order Siphonaptera) are obligate, hematophagous parasites of birds and mammals with medical interest because of their role in transmitting pathogens. From 2016 to 2019, we sampled the small mammal and associated flea communities in El Malpais National Conservation Area (El Malpais) in Cibola County, New Mexico. Among 898 mammalian specimens, 925 fleas representing 29 species were …

Prairie Dogs, Gary Witmer, Jon Grant, Kendra Cross

Wildlife Damage Management Technical Series

Prairie dogs (Cynomys spp.) occur throughout the prairie states of middle North America from Mexico northward into Canada. They occupy a variety of habitats from prairies to high mountain valleys and sage brush-dominated deserts. The most common species is the black-tailed prairie dog (Cynomys ludovicianus; Figure 1). Prairie dogs are considered a “keystone species.” They provide habitat for many other native, grassland species. Prairie dogs live in colonies or “towns” that can span hundreds to thousands of acres. Depending on the species, their presence is evident by their burrow system. Despite the many ecosystem benefits prairie dogs provide by modifying …

Blanding’S Turtle (Emydoidea Blandingii): Species Conservation Assessment, Melissa J. Panella, Colleen Rothe-Groleau

Nebraska Game and Parks Commission: Publications

The primary goal in development of at-risk species conservation assessments is to compile biological and ecological information that may assist conservation practitioners in making decisions regarding the conservation of species of interest. The Nebraska Natural Legacy Project recognizes the Blanding’s turtle (Emydoidea blandingii) as a Tier 1 at-risk species. Some general management recommendations are made here regarding Blanding’s turtles; however, conservation practitioners will need to use professional judgment to make specific management decisions based on objectives, location, and a multitude of variables. This resource was designed to share available knowledge of this at-risk turtle that will aid in the decision-making …

Let Emerging Plant Diseases Be Predictable, Valeria Trivellone

MANTER: Journal of Parasite Biodiversity

A prevalent concept for colonization and evolution among plant pathogens and their hosts stems from a post-Darwinian paradigm rooted in the formalized assumption of “specialized parasitism.” Seminal studies on rust fungi of socioeconomic importance integrated such an evolutionary perspective driven by the assumption of strict coevolution among pathogens and their plant hosts. Following this fundamentally unfalsifiable assumption, theories regarding host-switching for parasites were dismissed. If colonization occurred, this process would depend upon the origin of specific and novel mutations that allow infections of previously unexploited hosts or host groups, the acquisition of a broader host range. After a specific mutation …

An Emerging Infectious Disease Surveillance Platform For The 21st Century, Eloy Ortiz, Alicia Juarrero

MANTER: Journal of Parasite Biodiversity

Current vector surveillance programs are insufficient for coping with the emerging infectious disease crisis. In particular, current practices do not deploy sufficient information technology (IT) tools to generate actionable insights that can inform interventions and contain and mitigate the spread of vector-borne diseases. VectorAnalytica has developed a highly configurable and adaptable IT platform that imports, harmonizes, and integrates a range of data sources. The state-of-the-art backend development allows users to fully appreciate and understand the complexity of infectious disease dynamics without having to resort to additional statistical and GIS software packages. The platform yields actionable insights into outbreak patterns of …

Taking Action: Turning Evolutionary Theory Into Preventive Policies, Orsolya Molnár, Marina Knickel, Christine Marizzi

MANTER: Journal of Parasite Biodiversity

The emerging infectious disease (EID) crisis has been challenging global health security for decades, dealing substantial damage to all socioeconomic landscapes. Control measures have failed to prevent or even mitigate damages from an accelerating wave of EIDs, leading to the emergence and devastation caused by the COVID-19 pandemic. In the wake of the pandemic, we must critically review our public health policies and approaches. Current health security measures are based on the evolutionary theorem of host-parasite coevolution, which falsely deems EIDs as rare and unpredictable. The DAMA protocol (Document, Assess, Monitor, Act) is nested in a novel evolutionary framework that …

The Stockholm Paradigm Explains The Dynamics Of Darwin’S Entangled Bank, Including Emerging Infectious Disease, Salvatore J. Agosta

MANTER: Journal of Parasite Biodiversity

Pathogens and their hosts are embedded within the larger biosphere, what Darwin called the “entangled bank.” Emerging infectious disease occurs when a parasite “switches” to a new host. Understanding the dynamics of emerging disease requires understanding the dynamics of host-switching, which requires a more general understanding of how the biosphere and its constituent members cope when conditions change. The Stockholm paradigm is an integrative evolutionary framework that describes how living systems cope with change by oscillating between exploiting and exploring the geographical and functional dimensions of their environments. It combines organismal capacity, ecological opportunity, and the repeated external perturbations to …

Knowing The Biosphere: Documentation, Specimens, Archives, And Names Reveal Environmental Change And Emerging Pathogens, Eric P. Hoberg, Valeria Trivellone, Joseph A. Cook, Jonathan L. Dunnum, Walter A. Boeger, Daniel R. Brooks, Salvatore J. Agosta, Jocelyn P. Colella

MANTER: Journal of Parasite Biodiversity

One Health programs and trajectories are now the apparent standard for exploring the occurrence and distribution of emerging pathogens and disease. By definition, One Health has been characterized as a broadly inclusive, collaborative, and transdisciplinary approach with connectivity across local to global scales, which integrates the medical and veterinary community to recognize health outcomes emerging at the environmental nexus for people, animals, plants, and their shared landscapes. One Health has been an incomplete model, conceptually and operationally, focused on reactive and response-based foundations, to limit the impact of emerging pathogens and emerging infectious diseases and, as such, lacks a powerful …

The Evolutionary Dynamics Of Infectious Diseases On An Unstable Planet: Insights From Modeling The Stockholm Paradigm, Angie T.C. Souza, Sabrina B.L. Araujo, Walter A. Boeger

MANTER: Journal of Parasite Biodiversity

Emerging infectious diseases (EIDs) are, besides a question of food safety and public health, an ecological and evolutionary issue. The recognition of this condition combined with the accumulation of evidence that pathogens are not specialists in their original hosts evidences the need for understanding how the dynamics of interaction between pathogens and hosts occurs. The Stockholm Paradigm (SP) provides the theoretical fundaments to understand the dynamics of diseases and design proactive measures to avoid the emergence and reemergence of infectious diseases. In this review, we revisit the models that evaluate several aspects of the proposed dynamics of the SP, including …

A Field Synopsis, Systematic Review, And Meta-Analyses Of Cophylogenetic Studies: What Is Affecting Congruence Between Phylogenies?, Valeria Trivellone, Bernd Panassiti

MANTER: Journal of Parasite Biodiversity

We conducted a field synopsis and systematic meta-analysis of studies that carried out cophylogenetic analyses using algorithms and available software. We evaluated the influence of three factors—namely, cophylogenetic method, association, and ecosystem type—on the outcome of the analyses, that is, the degree of congruence between phylogenies of interacting species.

The published papers were identified using 4 different databases and 13 keywords; we included all studies for which statistical approaches to compare phylogenies (cophylogenetic analyses) of interacting lineages were used. After the initial screening, 296 studies were selected to extract response variable (outcome of the cophylogenetic analyses, i.e., congruent, incongruent, or …

The Stockholm Paradigm: Lessons For The Emerging Infectious Disease Crisis, Daniel R. Brooks, Walter A. Boeger, Eric P. Hoberg

MANTER: Journal of Parasite Biodiversity

The emerging infectious disease (EID) crisis represents an immediate existential threat to modern humanity. Current policies aimed at coping with the EID crisis are ineffective and unsustainably expensive. They have failed because they are based on a scientific paradigm that produced the parasite paradox. The Stockholm paradigm (SP) resolves the paradox by integrating four elements of evolutionary biology: ecological fitting, sloppy fitness space, coevolution, and responses to environmental perturbations. It explains why and how the EID crisis occurs and is expanding and what happens after an EID emerges that sets the stage for future EIDs. The SP provides a number …

The Dama Protocol, An Introduction: Finding Pathogens Before They Find Us, Eric P. Hoberg, Walter A. Boeger, Orsolya Molnár, Gábor Földvári, Scott Gardner, Alicia Juarrero, Vitaliy A. Kharchenko, Eloy Ortiz, Wolfgang Preiser, Valeria Trivellone, Daniel R. Brooks

MANTER: Journal of Parasite Biodiversity

Globally, humanity is coming to recognize the magnitude of the interactive crisis for emerging infectious disease (EID). Strategies for coping with EID have been largely in the form of reactive measures for crisis response. The DAMA protocol (Document, Assess, Monitor, Act), the operational policy extension of the Stockholm paradigm, constitutes a preventive/proactive dimension to those efforts. DAMA is aimed at focusing and extending human and material resources devoted to coping with the accelerating wave of EID. DAMA is integrative, combining efforts to strategically document the distribution of complex pathogen and host assemblages in the biosphere in the context of dynamic …
