Abnormal weather drives disease outbreaks in wild and agricultural plants

The paper shows how abnormal weather influences disease outbreaks in both wild and agricultural plants, finding that historical climate affects wild plants while warming increases agricultural disease risks.

Global change drivers and the risk of infectious disease

This study identifies global change drivers most associated with increases in infectious diseases across human and non-human systems.

Functional similarity, not phylogenetic relatedness, predicts the relative strength of competition

This study shows that functional similarity, not phylogenetic relatedness, predicts the strength of interspecific competition across ecological contexts.

Do host-consumed resources increase endoparasitic but decrease ectoparasitic infections?

The paper tests how food availability affects infection levels of two amphibian pathogens, finding that increased food reduces fungal infections but increases viral infections.

Environmental persistence but not per capita transmission rates of a chytrid fungus determines infection prevalence

The paper investigates how environmental factors affect the infection prevalence of the chytrid fungus Bd, finding that zoospore mortality, not transmission rates, drives variation in infection levels.

Identifying low risk insecticides to address both food shortages and the biocontrol of human schistosomiasis

The paper assesses the toxicity of insecticides to Macrobrachium prawns, finding pyrethroids more toxic and harmful to biocontrol agents in schistosomiasis-endemic areas.

Reducing disease and producing food: Effects of 13 agrochemicals on snail biomass and human schistosomes

This study evaluates the effects of 13 agrochemicals on snail biomass and human schistosomiasis risk, finding that fertilizers and insecticides increase snail biomass more than herbicides.

Reservoir host community and vector density predict human tick-borne diseases across the United States

This study links tick and reservoir host densities and diversity to human tick-borne disease prevalence across the U.S., showing varying relationships for different diseases.

Transmission of West Nile and other temperate mosquito-borne viruses peaks at intermediate environmental temperatures

The paper models temperature-dependent transmission of mosquito-borne viruses and finds optimal transmission at intermediate temperatures, with implications for climate change impacts.

Biodiversity loss underlies the dilution effect of biodiversity

The paper reanalyzes meta-analyses to show that biodiversity loss strengthens the dilution effect, particularly in disturbed ecosystems, resolving debates about its generality.

The application of community ecology theory to co-infections in wildlife hosts

This study applies priority effect theory to co-infections in frogs, showing that time lags between parasite exposures influence parasite loads and host outcomes.

A meta-analysis reveals temperature, dose, life stage, and taxonomy influence host susceptibility to a fungal parasite

This study meta-analyzes 58 amphibian-Bd infection experiments to show temperature, dose, life stage, and taxonomy influence host mortality.

Shifts in temperature influence how Batrachochytrium dendrobatidis infects amphibian larvae

This study shows that temperature shifts before Bd exposure affect Bd infection levels in amphibian larvae, with higher infection intensities after warming from 15°C to 20°C compared to cooling from 20°C to 15°C.

Effect of agrochemical exposure on Schistosoma mansoni cercariae survival and activity

This study examines how four insecticides affect the survival and activity of Schistosoma mansoni cercariae, finding that methamidophos increases survival but causes paralysis, potentially impacting disease transmission.

Evaluating Improvements to Exposure Estimates from Fate and Transport Models by Incorporating Environmental Sampling Effort and Landscape-level Contaminant Use

Spatial scale moderates the shape of the biodiversity-disease relationship

This study analyzes 231 biodiversity-disease relationships across 77 parasite species, finding non-linear, scale-dependent patterns where biodiversity generally inhibits disease at local scales but may increase disease at larger scales.

A Global Framework for Estimating Acclimation and Thermal Breadth Predicts Risk from Climate Change

The paper develops a global framework to estimate thermal acclimation and breadth, finding that body size and seasonality influence acclimation capacity and predicting extinction risk for amphibians.

Effects of agrochemicals on disease severity of Acanthostomum burminis infections (Digenea: Trematoda) in the Asian common toad, Duttaphrynus melanostictus

This study examines the effects of agrochemicals on the severity of Acanthostomum burminis infections in toad tadpoles and metamorphs, finding mixed additive and non-additive effects on survival and malformations.

Are the adverse effects of stressors on amphibians mediated by their effects on stress hormones?

This study investigates whether stressors like atrazine and Bd affect amphibians through corticosterone, finding that growth and infection tolerance are not primarily mediated by corticosterone.

A global synthesis of phenological responses to climate change

This study synthesizes global animal phenology data to show that temperature and precipitation drive phenological shifts in different latitudes, and body size influences the strength of these shifts.

A pesticide paradox: Fungicides indirectly increase fungal infections

This study shows that fungicides can increase fungal infections in amphibians by reducing their resistance, despite direct toxicity to the pathogen.

Detecting the impact of temperature on transmission of Zika, dengue and chikungunya using mechanistic models

This paper uses mechanistic models to show temperature-dependent transmission of Zika, dengue, and chikungunya, finding peak transmission between 26-29°C and seasonal limitations in temperate regions.
