Direct Effects of an Invasive European Buckthorn Metabolite on Embryo Survival and Development in Xenopus laevis and Pseudacris triseriata

  title={Direct Effects of an Invasive European Buckthorn Metabolite on Embryo Survival and Development in Xenopus laevis and Pseudacris triseriata},
  author={Allison B. Sacerdote and Richard B. King},
Abstract We demonstrate novel direct effects of an invasive plant metabolite on embryo development in the native Western Chorus Frog (Pseudacris triseriata) and a model organism, African Clawed Frog (Xenopus laevis). European buckthorn (Rhamnus cathartica) exhibits aggressive growth in amphibian breeding sites and releases the secondary metabolite, emodin, into soil and water. Emodin is known to have several deleterious, bioactive properties in mammals and birds, but its effects on amphibians… 

Invasive earthworms interact with abiotic conditions to influence the invasion of common buckthorn (Rhamnus cathartica)

The results suggest that the action of earthworms may provide a pathway through which buckthorn invades forests of the Upper Midwest United States, and researchers and managers should consider co-invasion of plants and earthworms when investigating invasibility and creating preemptive or post-inv invasion management plans.

Increased Temperature Influenced Growth and Development of Lithobates pipiens Tadpoles Exposed to Leachates of the Invasive Plant European Buckthorn (Rhamnus cathartica) and a Triclopyr Herbicide

The results encourage further examination of potential effects of global climate changes in combination with other environmental factors that may impact amphibian populations.

Effects of chemical management for invasive plants on the performance of Lithobates pipiens tadpoles

Results from the present study highlight the importance of considering both individual and combined effects of invasive plants and herbicides because they may have different outcomes for tadpole growth and development.

Interaction between invasive plant leaf litter and NaCl on two model amphibians

It is demonstrated that the presence of a pollutant may augment the effect of invasive leaf litter on amphibians, highlighting the need to consider concurrent stressors in invasive species management.

Effects of transgenic American chestnut leaf litter on growth and survival of wood frog larvae

Preliminary evidence is provided that American chestnuts may have formerly been an important source of food for forest‐dwelling amphibians and transgenic American chestnut litter generated as part of chestnut restoration efforts is unlikely to present direct novel risks to developing amphibian larvae in the forest environment.

Invasion Complexities: The Diverse Impacts of Nonnative Species on Amphibians

The dimensions of invasions are explored in the context of evolutionary history, anthropogenic disturbance, and climate change to determine the direct and indirect effects of nonnative species on amphibian health, genotypes, and native ecosystem structure.

Native anurans threatened by the alien tree Ligustrum lucidum in a seasonal subtropical forest

This study supports that woody alien invasion results in a reduction of native anuran richness and the dominance of a generalist anuran species in a seasonal semiarid subtropical forest.

The effects of novel leaf litter deposition on competitive, predator–prey and host–parasite interactions of American toad larvae

Wetland plant communities are changing rapidly due to a wide range of human activities. The deposition of leaf litter from novel plant communities can alter both the chemical and physical habitat of

Apparent widespread decline of the Boreal Chorus Frog ( Pseudacris maculata ) in eastern Ottawa

The reduced wetland cover in eastern Ottawa may be accompanied by reduced wetlands connectivity, making recolonization of wetlands difficult or impossible, and whether wetland connectivity has been reduced, is not shown.



Extracts of the invasive shrub Lonicera maackii increase mortality and alter behavior of amphibian larvae

An exploration of invasive plant extract effects on larvae of four amphibian species with behavioral observations designed to determine whether behavior can ameliorate the negative effects of exposure to invasive plant extracts highlights both a direct and indirect pathway by which invasive plant extracting may alter the ecological dynamics of native fauna.

Can secondary compounds of an invasive plant affect larval amphibians

This study implicates secondary plant compounds as a mechanism underlying the impact of an invasive plant on some but not all native fauna, hypothesizing that obligate gill breathers such as B. americanus tadpoles are highly sensitive to gill damage caused by high concentrations of phenolics.

Effects of an Invasive Plant, Chinese Tallow (Triadica sebifera), on Development and Survival of Anuran Larvae

It is suggested that breeding season may determine how each species survives and develops in an environment with T. sebifera leaf litter; therefore, negative effects may be short lived but pose a greater threat to species that breed soon after leaffall.

Ecology and ecosystem impacts of common buckthorn (Rhamnus cathartica): a review

Physiological studies have uncovered traits including shade tolerance, rapid growth, high photosynthetic rates, a wide tolerance of moisture and drought, and an unusual phenology that may give R. cathartica an advantage in the environments it invades.

Above‐ and Belowground Impacts of European Buckthorn (Rhamnus cathartica) on Four Native Forbs

Buckthorn's impacts on native plants exceed effects attributable to light levels and soil fertility, suggesting allelopathy, and additional research is needed to learn how best to control buckthorns' impacts onnative plant communities.

Evolutionary biology of plant defenses against herbivory and their predictive implications for endocrine disruptor susceptibility in vertebrates.

Diverse evidence of the influence of plant secondary compounds on vertebrate reproduction, including human reproduction is reviewed, suggesting that carnivores will be more susceptible than herbivores to endocrine-disrupting compounds of anthropogenic origin entering their bodies, and diverse herbivore lineages will be variably susceptible to any given natural or synthetic contaminant.

Traits, not origin, explain impacts of plants on larval amphibians.

It is suggested that to improve habitats for native fauna, managers should focus on assembling a plant community with desirable traits rather than focusing only on plant origin.

Rearing Xenopus laevis Life History Stages

These methods were developed to support laboratory exercises in an advanced animal developmental biology course and to provide new breeding stock for the department's colony and have proven to be reliable, cost-effective, and yielded consistent numbers of every life-cycle stage in an abridged life cycle time line.
