Ecological Correlates of Large-Scale Turnover in the Dominant Members of Pseudacris crucifer Skin Bacterial Communities
Animals host a wide diversity of symbiotic microorganisms that contribute important functions to host health, and our knowledge of what drives variation in the composition of these complex communities continue...

Comparative Analysis of Anuran Amphibian Skin Microbiomes Across Inland and Coastal Wetlands
Amphibians host a community of microbes on their skin that helps resist infectious disease via the dual influence of anti-pathogenic microbial species and emergent community dynamics. Many frogs rely on freshw...

Community richness of amphibian skin bacteria correlates with bioclimate at the global scale
Animal-associated microbiomes are integral to host health, yet key biotic and abiotic factors that shape host-associated microbial communities at the global scale remain poorly understood. We investigated glob...

Handling times and saturating transmission functions in a snail–worm symbiosis
All dynamic species interaction models contain an assumption that describes how contact rates scale with population density. Choosing an appropriate contact–density function is important, because different fun...

Open AccessResident Microbiome Disruption with Antibiotics Enhances Virulence of a Colonizing Pathogen
There is growing evidence that symbiotic microbes play key roles in host defense, but less is known about how symbiotic microbes mediate pathogen-induced damage to hosts. Here, we use a natural wildlife diseas...

Variation in Metabolite Profiles of Amphibian Skin Bacterial Communities Across Elevations in the Neotropics
Both the structure and function of host-associated microbial communities are potentially impacted by environmental conditions, just as the outcomes of many free-living species interactions are context-dependen...

Dispersal of a defensive symbiont depends on contact between hosts, host health, and host size
Symbiont dispersal is necessary for the maintenance of defense mutualisms in space and time, and the distribution of symbionts among hosts should be intricately tied to symbiont dispersal behaviors. However, w...

Variable infection of stream salamanders in the southern Appalachians by the trematode Metagonimoides oregonensis (family: Heterophyidae)
Many factors contribute to parasites varying in host specificity and distribution among potential hosts. Metagonimoides oregonensis is a digenetic trematode that uses stream-dwelling plethodontid salamanders as s...

Echinostoma trivolvis (Digenea: Echinostomatidae) second intermediate host preference matches host suitability
Many trematodes infect a single mollusk species as their first intermediate host, and then infect a variety of second intermediate host species. Determining the factors that shape host specificity is an import...

Species loss in the brown world: are heterotrophic systems inherently stable?
Determining the effects of species loss on ecosystems has received considerable attention given the current threats many ecosystems are facing. A significant body of research has yielded many insights to this ...

The combined influence of trematode parasites and predatory salamanders on wood frog (Rana sylvatica) tadpoles
Predators can have important impacts on host–parasite dynamics. For many directly transmitted parasites, predators can reduce transmission by removing the most heavily infected individuals from the population....

Impacts of biodiversity on the emergence and transmission of infectious diseases
Changes in biodiversity have the potential to either increase or reduce the incidence of infectious disease in plants and animals — including humans — because they involve interactions among species. At a mini...

Experimental examination of the effects of ultraviolet-B radiation in combination with other stressors on frog larvae
Ultraviolet-B radiation (UVB) is a ubiquitous stressor with negative effects on many aquatic organisms. In amphibians, ambient levels of UVB can result in impaired growth, slowed development, malformations, al...

Hatching of Echinostoma trivolvis miracidia in response to snail host and non-host chemical cues
Environmental cues are used by many organisms to time life history transitions and can be important for trematode host location. However, while much is understood about how larval trematodes locate hosts, much...

Effects of Atrazine and Metolachlor on the Survivorship and Infectivity of Echinostoma trivolvis Trematode Cercariae
Parasites play important roles in ecosystems and can be impacted by chemical inputs. In a series of experiments, we examined the impact of two common herbicides, metolachlor and atrazine, on a host–parasite sy...

Exposure of red-legged frog embryos to ambient UV-B radiation in the field negatively affects larval growth and development
Exposure to ultraviolet-B radiation (UV-B; 280–320 nm) has a wide array of effects on aquatic organisms, including amphibians, and has been implicated as a possible factor contributing to global declines and r...
