True bugs living on ant-defended acacias: evasion strategies and ant species preferences, in Costa Rica and Panama
(Universidad de Costa Rica, 2020)
Occurrence of Alkaloids in Grass Seeds Symbiotic With Vertically-Transmitted Epichloë Fungal Endophytes and Its Relationship With Antioxidants
(Frontiers Media SA, 2018-12)
Host organisms can acquire new functional traits through symbiosis. Seed-transmitted Epichloë fungal endophytes are known to protect host plants against herbivores and increase tolerance to abiotic stresses by alkaloids ...
Ontogenetic and trans-generational dynamics of a vertically transmitted fungal symbiont in an annual host plant in ozone-polluted settings
(Wiley Blackwell Publishing, Inc, 2020-10)
Tropospheric ozone is an abiotic stress of increasing importance in the context of global climate change. This greenhouse gas is a potent phytotoxic molecule with demonstrated negative effects on crop yield and natural ...
An ecological framework for understanding the roles of Epichloë endophytes on plant defenses against fungal diseases
(Elsevier, 2020-11)
Plants harbor a wide diversity of microorganisms in their tissues. Some of them have a long co-evolutionary history with their hosts, likely playing a pivotal role in regulating the plant interaction with other microbes ...
Epichloid endophytes confer resistance to the smut Ustilago bullata in the wild grass Bromus auleticus (Trin.)
(Academic Press Inc Elsevier Science, 2013-06-19)
In this work it was studied for the first time whether asexual Epichloë (Neotyphodium) endophytes of Bromus auleticus, protect their host plants against the pathogenic fungus Ustilago bullata.Seeds of two different ecotypes ...
Frenemy at the gate: Invasion by Pheidole megacephala facilitates a competitively subordinate plant ant in Kenya
(Ecological Society of America, 2020-10-24)
Biological invasions can lead to the reassembly of communities and understanding and predicting the impacts of exotic species on community structure and functioning are a key challenge in ecology. We investigated the impact ...
Sugary secretions of wasp galls: a want-to-be extrafloral nectar?
(Oxford University Press, 2017-06)
Background and Aims: The most widespread form of protective mutualisms is represented by plants bearing extrafloral nectaries (EFNs) that attract ants and other arthropods for indirect defence. Another, but less common, ...
Simulated folivory increases vertical transmission of fungal endophytes that deter herbivores and alter tolerance to herbivory in Poa autumnalis
(Oxford University Press, 2020-05)
• Background and Aims: The processes that maintain variation in the prevalence of symbioses within host populations are not well understood. While the fitness benefits of symbiosis have clearly been shown to drive changes ...
