Mark Roth
Primary Responsibilities/Activities:
As a member of the Amphibian and Reptile Team I provide assistance in the study of amphibian population statuses and threats to their persistence in the Midwest Region. My primary responsibilities are in support of the Amphibian Research and Monitoring Initiative (ARMI) and include operations in the field, laboratory, and office.
Research Interests
- Amphibian and reptile conservation
- Threatened, and endangered species
- Survey/monitoring design
- Life history and habitat characteristics of amphibians/reptiles
- Wildlife ecology
- Acoustics

1998 B.S., Wildlife Management, Biology, Resources Management, University of Wisconsin – Stevens Point
Science and Products
Carp Media Player
This product is a media player application and user guide. The application generates set-interval and random-interval media play schedules. When the application is used to execute the play schedule, it creates its own metadata documentation. The Carp Media Player documents the intended play schedule, generates a real-time log of the media played, and documents if there were any interruptions. This

Batrachochytrium salamandrivorans (Bsal) not detected in an intensive survey of wild North American amphibians
The salamander chytrid fungus (Batrachochytrium salamandrivorans [Bsal]) is causing massive mortality of salamanders in Europe. The potential for spread via international trade into North America and the high diversity of salamanders has catalyzed concern about Bsal in the U.S. Surveillance programs for invading pathogens must initially meet challenges that include low rates of occurrence on the l
Quantifying climate sensitivity and climate-driven change in North American amphibian communities
Changing climate will impact species’ ranges only when environmental variability directly impacts the demography of local populations. However, measurement of demographic responses to climate change has largely been limited to single species and locations. Here we show that amphibian communities are responsive to climatic variability, using >500,000 time-series observations for 81 species across 8

Multi-year data from satellite- and ground-based sensors show details and scale matter in assessing climate’s effects on wetland surface water, amphibians, and landscape conditions
Long-term, interdisciplinary studies of relations between climate and ecological conditions on wetland-upland landscapes have been lacking, especially studies integrated across scales meaningful for adaptive resource management. We collected data in situ at individual wetlands, and via satellite for surrounding 4-km2 landscape blocks, to assess relations between annual weather dynamics, snow durat
Challenges in complementing data from ground-based sensors with satellite-derived products to measure ecological changes in relation to climate – lessons from temperate wetland-upland landscapes
Assessing climate-related ecological changes across spatiotemporal scales meaningful to resource managers is challenging because no one method reliably produces essential data at both fine and broad scales. We recently confronted such challenges while integrating data from ground- and satellite-based sensors for an assessment of four wetland-rich study areas in the U.S. Midwest. We examined relati
Indicators of the statuses of amphibian populations and their potential for exposure to atrazine in four midwestern U.S. conservation areas
Extensive corn production in the midwestern United States has physically eliminated or fragmented vast areas of historical amphibian habitat. Midwestern corn farmers also apply large quantities of fertilizers and herbicides, which can cause direct and indirect effects on amphibians. Limited field research regarding the statuses of midwestern amphibian populations near areas of corn production has
Detecting emergence, growth, and senescence of wetland vegetation with polarimetric synthetic aperture radar (SAR) data
Wetlands provide ecosystem goods and services vitally important to humans. Land managers and policymakers working to conserve wetlands require regularly updated information on the statuses of wetlands across the landscape. However, wetlands are challenging to map remotely with high accuracy and consistency. We investigated the use of multitemporal polarimetric synthetic aperture radar (SAR) data a
Changes in historical Iowa land cover as context for assessing the environmental benefits of current and future conservation efforts on agricultural lands
Conservationists and agriculturists face unprecedented challenges trying to minimize tradeoffs between increasing demands for food, fiber, feed, and biofuels and the resulting loss or reduced values of other ecosystem services, such as those derived from wetlands and biodiversity (Millennium Ecosystem Assessment 2005a, 2005c; Maresch et al. 2008).
