Despite advances in sequencing, lack of standardization makes comparisons across studies challenging and hampers insights into the structure function microbial communities multiple habitats on a planetary scale. Here we present multi-omics analysis diverse set 880 community samples collected for Earth Microbiome Project. We include amplicon (16S, 18S, ITS) shotgun metagenomic sequence data, untargeted metabolomics data (liquid chromatography-tandem mass spectrometry gas chromatography...
Rhodolitica occulta gen. nov. et sp. (Clavulariidae) is described from Cocos Island National Park, Pacific Ocean, Costa Rica. The species was found at various islets and rocky outcrops around the island, 20−55 m in depth. genus characterised by tubular, single, erect anthosteles interconnected thin basal ribbon-like stolons on surfaces of living rhodoliths. are devoid fused sclerites, which only present stolons. Coenenchymal sclerites mostly spindles shapes, with a characteristic cylindrical...
Abstract Leaf‐cutter ants are a prominent feature in Neotropical ecosystems, but comprehensive assessment of their effects on ecosystem functions is lacking. We reviewed the literature and used our own recent findings to identify knowledge gaps develop framework quantify leaf‐cutter processes. disturb soil structure during nest excavation changing aeration temperature. They mix relatively nutrient‐poor from deeper layers with upper organic‐rich increasing heterogeneity carbon nutrients...
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 Examining the population structure and influence of recombination ecology on microbial populations makes great sense for understanding evolution speciation. Streptomycetes are a diverse group bacteria that widely distributed in nature rich source useful bioactive compounds; however, they rarely subjected to genetic investigations. In this study, we applied five-gene-based multilocus sequence analysis (MLSA) scheme 41 strains Streptomyces albidoflavus derived from sources, mainly...
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 involved pathogen defense and its microbiota relatively well studied, however, research focusing on cane lacking. We hypothesize microbial communities will differ between toads inhabiting different geographical regions Central Caribbean. To test our hypothesis, we compared three...
Amphibian skin is a suitable environment for rich communities of microorganisms, both beneficial and detrimental to the host. The amphibian cutaneous microbiota has been hypothesized play an important role as symbionts, protecting their hosts against disease. Costa Rica one most diverse assemblages amphibians in world we know very little about these tropical animals. For comparison with other studies, explore diversity bacterial employing16S rRNA amplicon sequencing swab samples from twelve...
The evolution of mass raiding has allowed army ants to become dominant arthropod predators in the tropics. Although a century research led many discoveries about behavioural, morphological and physiological adaptations ants, almost nothing is known molecular basis ant biology. Here we report genome iconic New World Eciton burchellii, show that it unusually compact, with reduced gene complement relative other ants. In contrast this overall reduction, particular subfamily (9-exon ORs)...
Heterogorgia abdita sp. nov. is a newly identified mesophotic octocoral species collected at Tigre shoal off Santa Elena Peninsula (Pacific Costa Rica). The new described based on distinctive morphological characters that classify it within the genus Heterogorgia. It characterised by its conspicuous small branching colony with prominent calyces and thin branches. While scleroma aligns genus, presence of club-like spindles notable, as these have previously been observed only in sole Atlantic...
Amphibians have declined around the world in recent years, parallel with emergence of an epidermal disease called chytridiomycosis, caused by chytrid fungus Batrachochytrium dendrobatidis (Bd). This has been associated mass mortality amphibians worldwide, including Costa Rica, and Bd is considered important contributor to disappearance this group vertebrates. While many species are susceptible disease, others show tolerance manage survive infection pathogen. We evaluated pathogen circulating...
