USDA Wildlife Services - Staff Publications

OBJECTIVE To evaluate efficacy of a novel vaccine against rabbit hemorrhagic disease virus 2 (RHDV2) in domestic rabbits.

ANIMALS 40 New Zealand White rabbits obtained from a commercial breeder.

PROCEDURES Rabbits were vaccinated and held at the production facility for the duration of the vaccination phase and transferred to Colorado State University for challenge with RHDV2. Rabbits were challenged with oral suspensions containing infectious virus and monitored for clinical disease for up to 10 days. Rabbits that died or were euthanized following infection were necropsied, and livers were evaluated for viral RNA via RT-PCR.

RESULTS None of the vaccinated animals …

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 …

Searching For The Soldier Pheromone: Behavioral Effects Of Soldiers And Soldier-Produced Chemicals In The Formosan Subterranean Termite, Coptotermes Formosanus (Blattodea: Rhinotermitidae)), Joseph Mccarthy

LSU Master's Theses

The Formosan subterranean termite, Coptotermes formosanus, is a eusocial insect and an invasive urban pest. Colonies function through a division of labor among castes (i.e., queens and kings, workers, and soldiers). Though soldiers are energetically expensive to maintain, C. formosanus has a relatively large soldier caste (~10% of the colony). Soldiers are physically unable to collect food or build tunnels but are regularly found with foraging workers. In some species, soldiers influence the worker foraging behavior. In C. formosanus, aside from defense, the roles soldiers play remains unknown. In this study, we determined if soldiers influence …

Reproductive Traits And Change In Body Shape Of Neonates In The Oak Forest Skink, Plestiodon Lynxe, Manuel Feria-Ortiz, Uri Omar García-Vázquez, Carlos Joaquín Pavón-Vázquez, Adrián Nieto-Montes De Oca

Publications and Research

Reproductive traits are critically important for understanding how organisms adapt to their respective environments. In this study, we provide information on relative litter mass (RLM) and other litter and neonate related characters of nine female Plestiodon lynxe captured in the field. We also recorded seven body dimensions in 16 neonates and 15 two-month juveniles, and on the basis of these dimensions we compared the body shape of these two age classes to detect changes in the proportions of body parts. The average litter size (4.55) is larger than that found in other viviparous species of Plestiodon, but smaller than …

The 3p Framework: A Comprehensive Approach To Coping With The Emerging Infectious Disease Crisis, Orsolya Molnár, Eric Hoberg, Valeria Trivellone, Gábor Földvári, Daniel R. Brooks

MANTER: Journal of Parasite Biodiversity

The COVID-19 pandemic is the latest example of the profound socioeconomic impact of the emerging infectious disease (EID) crisis. Current health security measures are based on a failed evolutionary paradigm that presumes EID is rare and cannot be predicted because emergence requires the prior evolution of novel genetic capacities for colonizing a new host. Consequently, crisis response through preparation for previously emerged diseases and palliation following outbreaks have been the only health security options, which have become unsustainably expensive and unsuccessful. The Stockholm paradigm (SP) is an alternative evolutionary framework that suggests host changes are the result of changing conditions …

Reanalysis Of The Yunnan Population Of Scorpiops Kubani With A Description Of A New Species, Scorpiops Lowei Sp. N. (Scorpiones: Scorpiopidae), Victoria Tang

Euscorpius

The Yunnan population of Scorpiops kubani (Kovařík, 2004) is reassessed based on recently collected specimens from this region. A misidentification of that species is revealed, which leads to a description of a new species, Scorpiops lowei sp. n.

A New Species Of Scorpiops Peters, 1861 From Yunnan Province, China, With A Preliminary Review Of Its Congeners In Yunnan (Scorpiones: Scorpiopidae), Victoria Tang

Euscorpius

A new species of Scorpiops Peters, 1861, Scorpiops tongtongi sp. n., is described from Yingjiang, Yunnan Province, China, based on a single adult female. The morphology of the new species is fairly distinguishable from other congeners in Yunnan even with unaided eye; it is characterized by the following combination of characters in female: a pair of moderately robust pedipalp chelae without proximal lobes, small median ocular tubercle, short superciliary carinae, less granulated tergites, proportionally elongate metasoma and relatively short and bulbous vesicle. The coloration of the new species also differs from other congeners in Yunnan by being brownish in …

Timber Rattlesnake (Crotalus Horridus): A Species Conservation Assessment For The Nebraska Natural Legacy Project, Melissa J. Panella, Dan Fogell, Colleen Rothe-Groleau

Nebraska Game and Parks Commission Publications

The primary goal in the 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 timber rattlesnake (Crotalus horridus) as a Tier 1 at-risk species. Provided here are general management recommendations regarding timber rattlesnakes. Conservation practitioners will need to use their professional judgment for management decisions based on objectives, location, and site-specific conditions. Based on the body of literature and available data, this species conservation assessment provides an overview of our current knowledge of timber …

Report Of Thanatosis In The Central American Scorpions Tityus Ocelote And Ananteris Platnicki (Scorpiones: Buthidae), Felipe Triana, Fabián Bonilla, Adriana Alfaro-Chinchilla, Carlos Víquez, Cecilia Díaz, Mahmood Sasa

Euscorpius

Thanatosis, or tonic immobility, is a behavior where animals adopt a motionless posture after a physical contact or very close proximity of a predator. This behavior has been described in a wide range of taxa, from invertebrates to vertebrates. For scorpions, tonic immobility has been reported in two buthids, Tityus pusillus and Tityus cerroazul, one hormurid, Liocheles australasiae, and one scorpiopsid, Scorpiops jendeki. Here we report other cases of this thanatosis for two buthid scorpions from lower Central America: Tityus ocelote and Ananteris platnicki. Thanatosis in these species were observed in wild, but was better documented …

Seasonal Habitat Selection By American White Pelicans, Frederick L. Cunningham, Guiming Wang, D. Tommy King

USDA Wildlife Services - Staff Publications

Resource utilization strategies of avian migrants are a major concern for conservation and management. Understanding seasonal habitat selection by migratory birds helps us explain the ongoing continental declines of migratory bird populations. Our objective was to compare the secondorder and third-order habitat selection by the American White Pelican (Pelecanus erythrorhynchos; hereafter pelican) between the breeding and non-breeding grounds. We tested the Lack hypothesis that habitat selection by migratory birds is stronger on the breeding grounds than on the nonbreeding grounds. We used random-effect Dirichlet-multinomial models to estimate the second-order habitat selection between the seasons with the GPS locations …

Effects Of Early‑Life Experience On Innovation And Problem‑Solving In Captive Coyotes, Andrew C. Garcia, Mitchell A. Parsons, Julie K. Young

USDA Wildlife Services - Staff Publications

Early-life experience often shapes behaviors like innovation and exploration. These behaviors are important to animals encountering novel food resources in diverse habitats, such as mesocarnivores in urban areas. To understand if early-life experiences impact later-life behavior, we examined how coyotes (Canis latrans) responded to a multi-access puzzle box at two life stages: pup (~ 7 weeks) and dispersal (~ 10 months). We first exposed pups, still living with their parents and littermates, to a baited puzzle box. At dispersal age, we again tested both these pups and an age-matched control group that was not exposed to the puzzle …

Status Of Barking Owl Ninox Connivens In South-West Australia, Robert A. Davis, Leo Joseph, Ronald E. Johnstone

Research outputs 2022 to 2026

Barking Owl Ninox connivens has two recognised subspecies in Australia: N. c. connivens and N. c. peninsularis. N. c. connivens currently includes the isolated south-west Australian population, which is separated from eastern populations by the Nullarbor Plain and from N. c. peninsularis to the north. N. c. connivens in south-west Australia occurs from near Perth in the north, east to Northam and south-east to Katanning and Bremer Bay; it has been treated subspecifically as N. c. addendaMathews, 1912, but this name is not currently in use. Given concern over the apparent rarity of the south-west Australian population, we sought to …

Summer Field Report, June-July 2022, W. Ross Silcock

Nebraska Bird Review

As always, the summer season produces surprises, and this year was no exception. Surprises fall into different categories, though: genuine statewide rarities, within-state distributional rarities, and, of course in summer, nesting records at new locations, population notes, late and early dates and high numbers, increased knowledge about subspecies in the state, and miscellaneous things of interest. These categories are covered separately below after some housekeeping comments.

“Genuine statewide rarities” were led by the first state record Limpkin found by Karen Kader and seen by many in Sarpy Co. Potential 2nd or so state records were a Mexican Duck in Scotts …

Divergent Neural And Endocrine Responses In Wild-Caught And Laboratory-Bred Rattus Norvegicus, Joanna Jacob, Sally Watanabe, Jonathan Richardson, Nick Gonzales, Emily Ploppert, Garet Lahvis, Aaron Shiels, Sadie Wenger, Kelly Saverino, Janhavi Bhalerao, Brendan Crockett, Erin Burns, Olivia Harding, Krista Fischer-Stenger, Kelly Lambert

USDA Wildlife Services - Staff Publications

Although rodents have represented the most intensely studied animals in neurobiological investigations for more than a century, few studies have systematically compared neural and endocrine differences between wild rodents in their natural habitats and laboratory strains raised in traditional laboratory environments. In the current study, male and female Rattus norvegicus rats were trapped in an urban setting and compared to weight-and sex-matched conspecifics living in standard laboratory housing conditions. Brains were extracted for neural assessments and fecal boli were collected for endocrine [corticosterone and dehydroepiandrosterone (DHEA)] assays. Additionally, given their role in immune and stress functions, spleen and adrenal weights …
