Impact of intraspecific variation in insect microbiomes on host phenotype and evolution

The ISME Journal, Journal Year: 2023, Volume and Issue: 17(11), P. 1798 - 1807

Published: Sept. 2, 2023

Abstract Microbes can be an important source of phenotypic plasticity in insects. Insect physiology, behaviour, and ecology are influenced by individual variation the microbial communities held within insect gut, reproductive organs, bacteriome, other tissues. It is becoming increasingly clear how microbiome for fitness, expansion into novel ecological niches, environments. These investigations have garnered heightened interest recently, yet a comprehensive understanding intraspecific assembly function these insect-associated shape insects still lacking. Most research focuses on core associated with species ignores variation. We argue that among driver evolution, we provide examples showing such influence fitness health insects, invasions, their persistence new environments, responses to global environmental changes.

Beaks promote rapid morphological diversification along distinct evolutionary trajectories in labrid fishes (Eupercaria: Labridae)

Evolution, Journal Year: 2023, Volume and Issue: 77(9), P. 2000 - 2014

Published: June 21, 2023

Abstract The upper and lower jaws of some wrasses (Eupercaria: Labridae) possess teeth that have been coalesced into a strong durable beak they use to graze on hard coral skeletons, hard-shelled prey, algae, allowing many these species function as important ecosystem engineers in their respective marine habitats. While the ecological impact is well understood, questions remain about its evolutionary history effects this innovation downstream patterns morphological evolution. Here we analyze 3D cranial shape data phylogenetic comparative framework paleoclimate modeling reconstruct evolution labrid across 205 species. We find evolved beaks three times independently, once within odacines twice parrotfishes Pacific Atlantic Oceans. an increase rate Scarus+Chlorurus+Hipposcarus (SCH) clade likely driven by intramandibular joint. Paleoclimate shows SCH rapidly morphologically diversified during middle Miocene. hypothesize possession coupled with favorable environmental conditions allowed diversify.

Foliar herbivory modifies arbuscular mycorrhizal fungal colonization likely through altering root flavonoids

Functional Ecology, Journal Year: 2023, Volume and Issue: 38(1), P. 259 - 271

Published: Oct. 25, 2023

Abstract Insect herbivory may influence arbuscular mycorrhizal (AM) fungal colonisation by changing plant chemistry, and these effects can vary from negative to positive. Yet the underlying mechanisms are unclear. We investigated AM colonization of Chinese tallow tree ( Triadica sebifera ) after exposing its seedlings four different foliar‐feeding insects at two levels herbivory. then examined potential role induced carbon allocation secondary metabolites, particularly flavonoids, in colonization. Light (ca. 10% leaf area removed) promoted early fungi whereas heavy 60% decreased it. Root flavonoids were increased (in short‐term) under light but Further, herbivore‐induced changes root positively correlated with those colonisation. Moreover, quercitrin, one root‐secreted could mediate responses. Surprisingly, however, was not roots or exudates. show that responses insect least partially flavonoid‐based depend on intensity. Our work highlights importance metabolites rather than interactions between above‐ground below‐ground mycorrhiza. Read free Plain Language Summary for this article Journal blog.

The Abrolhos Nominally Herbivorous Coral Reef Fish Acanthurus chirurgus, Kyphosus sp., Scarus trispinosus, and Sparisoma axillare Have Similarities in Feeding But Species-Specific Microbiomes

Abstract Coral reefs rely heavily on reef fish for their health, yet overfishing has resulted in decline, leading to an increase fast-growing algae and changes ecosystems, a phenomenon described as the phase-shift. A clearer understanding of intricate interplay between herbivorous, food, gut microbiomes could enhance health. This study examines microbiome isotopic markers (δ 13 C δ 15 N) four key nominally herbivorous species ( Acanthurus chirurgus , Kyphosus sp., Scarus trispinosus Sparisoma axillare ) Southwestern Atlantic’s Abrolhos Reef systems. Approximately 16.8 million 16S rRNA sequences were produced species, with average 317,047 ± 57,007 per species. Bacteria such Proteobacteria, Firmicutes, Cyanobacteria prevalent microbiomes. These show unique that result from co-diversification, diet, restricted movement. Coral-associated bacteria Endozoicomonas Rhizobia Ruegeria found abundance contents parrotfish Sc.

Microbiome transfer from native to invasive species may increase invasion risk

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2024, Volume and Issue: 291(2034)

Published: Nov. 1, 2024

In a fast-changing world, understanding how organisms adapt to their environment is pressing necessity. Research has focused on genetic adaptation, while our of non-genetic modes still in its infancy. The host-associated microbiome can be considered mode which strongly influence an organism’s ability cope with environment. However, the role host ecological dynamics largely unexplored, particularly animal communities. Here, we discuss following hypothesis: invasive species may rapidly local conditions by adopting beneficial microbes from similar co-occurring native species. This occurs when invader’s fitness influenced adaptation that facilitated acquired microbiomes. We present minimal mathematical model explore this hypothesis and show delayed acquisition explain occurrence invasion lag. Overall, results contribute broadening conceptualization rapid via transfer offer insights towards designing early intervention strategies for management.
