Pathogens can have strong negative effects on individual fitness that scale up to influence population dynamics. Because of this, understanding the ecological contexts that shape pathogen transmission and prevalence is critical for understanding community dynamics and ecosystem function. Puccinia mo

The scale of influence of hydrological and thermal conditions on disease remains uncertain for most wild plant pathosystems, thus restricting our ability to predict the impacts of climate change. Analysis of the spatiotemporal spread of a fungal rust pathogen throughout four naturally occurring flax

Climate change and shifting environmental conditions can allow pathogens to spread into previously unburdened areas. For plant pathogens, this dynamic has the potential to disrupt natural ecosystem equilibria and human agriculture, making predicting plant pathogen range shifts increasingly important

In this study, we performed several transect surveys over the course of the 2021 summer field season to assess potential ecogeographical range determinants for Lewis flax ( Linum lewisii ) and its pathogen, flax rust ( Melamspora lini ), in the area surrounding the Rocky Mountain Biological Laborato

Activation of the complement system is mediated by the interaction between pathogens and pattern recognition molecules (PRMs); mannose-binding lectin (MBL), ficolins, and collectin-10/-11 from the lectin pathway and C1q from the classical pathway.

Simultaneous or sequential attack by herbivores and microbes is common in plants. Many seed plants exhibit a defence trade-off against chewing herbivorous insects and leaf-colonizing ( phyllosphere ) bacteria, which arises from cross-talk between the phytohormones jasmonic acid (JA, induced by many

Many biotic interactions influence community structure, yet most distribution models for plants have focused on plant competition or used only abiotic variables to predict plant abundance. Furthermore, biotic interactions are commonly context-dependent across abiotic gradients. For example, plant-pl

Climate change in Colorado has already increased temperatures by 2 ℉ and is predicted to continue to rise. Precipitation during winter months is predicted to increase, while projected precipitation for the spring, summer and fall is still uncertain. It is important to understand how saxicolous liche

Rising global temperatures are predicted to alter community dynamics by shifting species ranges and altering biotic interactions. Herbivory is expected to increase with prolonged growing seasons and heightened animal metabolic rates; pathogen damage may increase as well. Thus, we investigated whethe

AbstractSimultaneous or sequential attack by herbivores and microbes is common in plants. Many seed plants exhibit a defence trade‐off against chewing herbivorous insects and leaf‐colonizing (‘phyllosphere’) bacteria, which arises from cross‐talk between the phytohormones jasmonic acid (JA, induced

Host plant genotypes often interact with the genotypes of pathogenic bacteria in order to affect the susceptibility phenotype with regards to herbivory. Often specialist herbivores illicit host plant production of jasmonic acid while biotrophic pathhogens induce a response of Salicylic acid, both of

Understanding the processes and mechanisms that underlie patterns of species diversity and distribution is a fundamental goal of community ecology. Elevational gradients enable ecologists to tease apart ecological drivers and mechanisms as reflected by distribution patterns. In spite of the consider

Black sage aphids, Obtusicauda frigidae, are infected by the bacterial endosymbiont Hamiltonella defensa. The bacteria confers a resistance to parasitism by the solitary endoparastic wasp Aphidius ervi. The bacteria also confers a number of other advantages to the aphids. Despite the number of advan

Parasites have the potential to alter population dynamics by decreasing fitness and increasing mortality of their hosts. Changes in ecosystems may also create scenarios that are more conducive to higher infection or parasitism. This survey examined parasitism of Bombus by Crithidia bombi, Nosema bom
