Evidence for Widespread Associations between Neotropical Hymenopteran Insects and Actinobacteria
(2017)
The evolutionary success of hymenopteran insects has been associated with complex physiological and behavioral defense mechanisms against pathogens and parasites. Among these strategies are symbiotic associations between ...
Papel de la bacteria endosimbionte Wolbachia en el control de enfermedades vectoriales: dengue, zika y chikunkunya
(2017)
Wolbachia es un género de bacterias perteneciente al orden Rickettsiales, que participa en diversas relaciones simbióticas con varios organismos, principalmente artrópodos y nematodos. Debido a su capacidad para inducir ...
Characterization of Batrachochytrium dendrobatidis Inhibiting Bacteria from Amphibian Populations in Costa Rica
(2017)
Global amphibian declines and extinction events are occurring at an unprecedented rate. While several factors are responsible for declines and extinction, the fungal pathogen Batrachochytrium dendrobatidis (Bd) has been ...
Characterization of the Skin Microbiota of the Cane Toad Rhinella cf. marina in Puerto Rico and Costa Rica
(2017)
Rhinella marina is a toad native to South America that has been introduced in the Antilles, likely carrying high loads of microorganisms, potentially impacting local community diversity. The amphibian skin is involved in ...
Bacteria contribute to plant secondary compound degradation in a generalist herbivore system.
(2020)
Herbivores must overcome a variety of plant defenses, including coping
with plant secondary compounds (PSCs). To help detoxify these defensive chemicals,
several insect herbivores are known to harbor gut microbiota with ...
Burkholderia from fungus gardens of fungus-growing ants produce antifungals that inhibit the specialized parasite Escovopsis.
(2021-06)
Within animal-associated microbiomes, the functional roles of specific microbial taxa are often uncharacterized. Here, we use the fungus-growing ant system, a model for microbial symbiosis, to determine the potential ...
Ultrastructural and microbial analyses of cellulose degradation in leaf-cutter ant colonies
(2017)
Leaf-cutter ants (Atta and Acromyrmex) use fresh leaves to cultivate a mutualistic fungus (Leucoagaricus gongylophorus) for food in underground gardens. A new ant queen propagates the cultivar by taking a small fragment ...
Soybean protease inhibitors increase Bacillus thuringiensis subs. israelensis toxicity against Hypothenemus hampei
(2020)
The coffee berry borer (Hypothenemus hampei Ferrari, CBB) is one of the most devastating pests on coffee plantations around the world. Although CBB is susceptible to the effect of δ–endotoxins ...
Low diversity and host specificity in the gut microbiome community in species of Eciton army ants (Formicidae: Dorylinae) in a Costa Rican rainforest
(2022-12)
Neotropical army ants of the genus Eciton are top arthropod predators in tropical rainforests. Microbial symbionts, including Unclassified Firmicutes (UF) and Unclassified Entomoplasmatales (UE), are associated with this ...
The genomic basis of army ant chemosensory adaptations
(2021-09)
The evolution of mass raiding has allowed army ants to become dominant arthropod predators in the tropics. Although a century of research has led to many discoveries about behavioural, morphological and physiological ...
