Population Status of the Eastern Hellbender (Cryptobranchus alleganiensis alleganiensis) in Indiana
TLDR
This study documents the continued decline of the Eastern Hellbender over the past 25 years in the last known remaining population in southern Indiana, which consists almost exclusively of large, older-age class individuals that show limited signs of reproduction. Expand
Population Genetics of the Eastern Hellbender (Cryptobranchus alleganiensis alleganiensis) across Multiple Spatial Scales
TLDR
Understanding levels of genetic variation and differentiation at multiple spatial and biological scales will enable natural resource managers to make more informed decisions and plan effective conservation strategies for cryptic, lotic species. Expand
HEALTH AND HABITAT QUALITY ASSESSMENT FOR THE EASTERN HELLBENDER (CRYPTOBRANCHUS ALLEGANIENSIS ALLEGANIENSIS) IN INDIANA, USA
TLDR
A baseline for hematology and water-quality parameters is established that can be used as a model for evaluating population health throughout the hellbender range. Expand
A Comparison of Sperm Health in Declining and Stable Populations of Hellbenders (Cryptobranchus alleganiensis alleganiensis and C.a. bishopi)
TLDR
This method for assessing male reproductive health provides the first baseline comparative study among populations of this cryptic species in decline and has broad implications for use in monitoring male health across the distribution of the eastern hellbender. Expand
Learning to Avoid Dangerous Habitat Types by Aquatic Salamanders, Eurycea tynerensis
TLDR
Salamanders showed significant avoidance of the habitat where they had previously encountered chemical cues from sculpin in comparison to the non-predatory controls, and learning to avoid dangerous habitats may be particularly important for prey whose predators are visually cryptic ambush foragers, such as scul pin. Expand
iNaturalist as an engaging tool for identifying organisms in outdoor activities
We evaluated an emerging smartphone application, iNaturalist, to increase taxonomic identification and engage first-year undergraduate biology majors in outdoor laboratories of aquatic ecosystems (...
Student Attitudes Towards Online Education during the COVID-19 Viral Outbreak of 2020: Distance Learning in a Time of Social Distance
In this paper, undergraduate student attitudes towards rapidly shifting to an entirely online learning environment were assessed due to COVID-19. In addition, surveys on perceptions aboutExpand
Isolation and development of 12 polymorphic tetranucleotide microsatellite markers for the eastern hellbender (Cryptobranchus alleganiensis alleganiensis)
TLDR
12 polymorphic microsatellite loci were developed for the eastern hellbender and will be used to examine population genetic structure across the geographic range of this declining species. Expand
Projected population persistence of eastern hellbenders (Cryptobranchus alleganiensis alleganiensis) using a stage-structured life-history model and population viability analysis
TLDR
A stage-structured, life-history model was developed to examine the effects of varying levels of egg, juvenile, and adult survivorship on abundance, recruitment, and long-term population projections and revealed that survival of adult and egg/larvae life- history stages are the most important for focused management efforts.
