Modern venomics—Current insights, novel methods, and future perspectives in biological and applied animal venom research

GigaScience, Год журнала: 2022, Номер 11

Опубликована: Янв. 1, 2022

Abstract Venoms have evolved >100 times in all major animal groups, and their components, known as toxins, been fine-tuned over millions of years into highly effective biochemical weapons. There are many outstanding questions on the evolution toxin arsenals, such how venom genes originate, contributes to fitness venomous species, which modifications at genomic, transcriptomic, protein level drive evolution. These received particularly little attention outside snakes, cone snails, spiders, scorpions. Venom compounds further become a source inspiration for translational research using diverse bioactivities various applications. We highlight here recent advances new strategies modern venomics discuss technological innovations multi-omic methods dramatically improve animals. The study genomes through CRISPR knockdown technologies will increase our understanding toxins evolve functions they different ontogenetic stages during development Mass spectrometry imaging combined with spatial transcriptomics, situ hybridization techniques, computer tomography gives us insights distribution system function apparatus. All these evolutionary biological contribute more efficiently identify compounds, can then be synthesized or produced adapted expression systems test bioactivity. Finally, we critically agrochemical, pharmaceutical, therapeutic, diagnostic (so-called translational) aspects venoms from humans benefit.

Lessons From the Western Atlantic Lionfish Invasion to Inform Management in the Mediterranean

Frontiers in Marine Science, Год журнала: 2022, Номер 9

Опубликована: Апрель 20, 2022

Major invasions of Indo-Pacific lionfish ( Pterois volitans and P. miles ) are underway in the Western Atlantic Ocean Mediterranean Sea. While establishment is perhaps most well-studied marine fish invasion to date, rapidly expanding more recent has received less attention. Here we review synthesize successes failures from two decades management give policy recommendations for their Mediterranean. Two failed approaches that were attempted multiple times advise against (1) feeding native promote predation (2) implementing bounty programs incentivize harvest. Broadly, important lessons recommend include conducting routine removals by spearfishing with scuba, which can effectively suppress local abundances lionfish; encouraging development recreational commercial fisheries, long-term, sustainable population control; and, (3) engaging communities resource users (e.g., removal tournaments), concurrently achieve objectives promoting removals, market-development, research, public education. Managers often needed adapt current conservation policies enable areas where scuba was otherwise prohibited purposes. The risk abusing these mitigated through use gear restrictions, diver trainings, participatory integrated divers stakeholder organizations research management. Our practices Sea found many our recommended not being done indicate potential opportunities implement these. We expect fully work continues towards multinational cooperation facilitate regional coordination control, efforts respect invasion. As other major biological invasions, unconstrained political borders control will require rapid strategic broad among between governments stakeholders.

Lionfish on the loose: Pterois invade shallow habitats in the tropical southwestern Atlantic

Frontiers in Marine Science, Год журнала: 2022, Номер 9

Опубликована: Авг. 1, 2022

Lionfish ( Pterois spp.) evolved in the Indo-Pacific with predators and prey invaded regions (e.g., Caribbean Sea Mediterranean) where no such balance yet exists. In 2020, four lionfish were recorded on mesophotic reefs of Amazon offshore Coast Fernando de Noronha Archipelago. However, until now, there records invasive Brazilian nearshore waters or even a high number individuals. this article, we report continuing invasion process along Province by multiple sightings (72) from March to May 2022 estuaries, seagrass beds, artificial natural across 240 km coast. These are first coastal northeast Brazil shallowest (1–16 m) South Atlantic tropical waters. The largest simultaneous breakwaters, fishing weirs, marambaias (artificial used as grounds) Northeastern coast indicate that these man-made structures suitable habitats for species. Most (58%) weirs. Moreover, detection invasions marginal reefs, two marine protected areas characterized moderately turbid water sedimentation rates highlights adaptability lionfish, making it extremely difficult divers fishers capture them. We call an urgent management plan considering region hosts level endemism, rare and/or cryptic taxa, which increases risk impacts since primary prey.

Trait-based indicators of resource selection by albacore tuna in the California Current Large Marine Ecosystem

Ecological Indicators, Год журнала: 2024, Номер 158, С. 111473 - 111473

Опубликована: Янв. 1, 2024

As global climate change reorganizes marine ecosystems, understanding how predators will respond to variable prey resources is critical forecasting future community dynamics. Prey traits that affect the foraging process and recur across unrelated taxa offer a means better anticipate predator resource use by simplifying complex Here we compare taxonomic trait-based indicators of selection for albacore tuna (Thunnus alalunga), commercially valuable pelagic undergoing climate-driven range shifts. We synthesized datasets from 2005 2019 evaluate diets in relation availability estimates shipboard surveys California Current Large Marine Ecosystem. Analyses with these data reveal trawl sample different aspects system, consuming subset identified within trawls. Albacore consistently selected coastal are schooling, undefended, silvered countershaded, have high energy density — suggesting ecological mechanisms driving outcomes may be conserved time space. Ecological mediating predator-prey interactions distinguished assemblages sampled trawls years regions. demonstrate traits-based approach simplifies taxonomically diverse tool facilitate predictions changing environments.

Submersibles Greatly Enhance Research on the Diversity of Deep-Reef Fishes in the Greater Caribbean

Frontiers in Marine Science, Год журнала: 2022, Номер 8

Опубликована: Янв. 31, 2022

Understanding the diversity and ecology of deep-reef fishes is challenging. Due to intensive widely dispersed sampling, Greater Caribbean (GC) fauna species found on shallow reefs much better characterized than restricted mesophotic (40–130 m) rariphotic (130–300 depths. Our knowledge about based ship-board sampling recent use rebreather diving, remotely operated vehicles (ROVs), baited remote underwater videos, crewed submersibles. Submersible research GC began in 1960s has flourished over last decade through by Smithsonian Institution’s Deep Reef Observation Project (DROP). Here we quantify contribution submersible research, particularly surge DROP, our understanding fish GC. We compared shallow- faunas three sites subjected DROP without such research. increased size deep at islands ∼9-fold, they have ∼2–4 times those other sites. Those high proportions small cryptobenthic fishes, which also represent a major component faunas. That rate discovery (collection) new ∼6-fold accounts for 31% first discovered within Substantial numbers each were not two. This indicates that parts likely harbor many undetected significantly underestimated. These results show submersibles are versatile, highly productive tools studies. They allow long-duration dives any depth, while offering unparalleled views their surroundings study (e.g., DROP’s definition assemblage from depth distributions). Submersibles can efficiently collect reef broad range taxa, ecotypes sizes, leading more comprehensive regional fauna.
