The evolutionary success of hymenopteran insects has been associated with complex physiological and behavioral defense mechanisms against pathogens parasites. Among these strategies are symbiotic associations between Hymenoptera antibiotic-producing Actinobacteria, which provide protection to insect hosts. Herein, we examine culturable Actinobacteria 29 species tropical that span five families, including Apidae (bees), Vespidae (wasps), Formicidae (ants). In total, 197 isolates were obtained...
Many insects have been associated with actinobacteria in protective symbiosis where antimicrobial metabolites inhibit host pathogens. However, the microbiota of neotropical such as stingless-bee Tetragonisca angustula is poorly explored. T. a meliponid bee widely distributed Latin America, its honey traditionally exploited because ethno-pharmacological properties and activity has demonstrated. Also, well-structured nest this species allows exploration different components. Even though...
Abstract Global atmospheric methane growth rates have wildly fluctuated over the past three decades, which may be driven by proportion of tropical land surface saturated water. The El Niño/Southern Oscillation Event (ENSO) cycle drives large‐scale climatic trends globally, with Niño events typically bringing drier weather than La Niña. In a lowland wet forest in Costa Rica, we measured flux bimonthly from March 2016 to June 2017 and using an automated chamber system. We observed strong...
Deciphering the ecological roles of plant secondary metabolites requires integrative studies that assess both allocation patterns compounds and their bioactivity in interactions. Secondary have been primarily studied leaves, but many are unique to fruits can numerous potential interactions with mutualists (seed dispersers) antagonists (pathogens predators). We described 10 alkenylphenol from species Piper sancti-felicis (Piperaceae), quantified intraplant across tissues fruit development,...
Symbioses with microbes play a pivotal role in the evolutionary success of insects, and can lead to intimate host-symbiont associations. However, how host maintains stable symbiosis its beneficial partners while keeping antagonistic check remains incompletely understood. Here, we uncover mechanism by which protects symbiont from host's own broad-range antimicrobial defense during transmission. Beewolves, group solitary digger wasps (Hymenoptera: Crabronidae), provide their brood cells...
