The biomass distribution on Earth

Proceedings of the National Academy of Sciences, Journal Year: 2018, Volume and Issue: 115(25), P. 6506 - 6511

Published: May 21, 2018

Significance The composition of the biosphere is a fundamental question in biology, yet global quantitative account biomass each taxon still lacking. We assemble census all kingdoms life. This analysis provides holistic view and allows us to observe broad patterns over taxonomic categories, geographic locations, trophic modes.

Merging paleobiology with conservation biology to guide the future of terrestrial ecosystems

Science, Journal Year: 2017, Volume and Issue: 355(6325)

Published: Feb. 10, 2017

Looking back to move forward The current impacts of humanity on nature are rapid and destructive, but species turnover change have occurred throughout the history life. Although there is much debate about best approaches take in conservation, ultimately, we need permit or enhance resilience natural systems so that they can continue adapt function into future. In a Review, Barnosky et al. argue way do this look at paleontological as understand how ecological maintained, even face change. Science , issue p. eaah4787

Diversity begets stability: Sublinear growth and competitive coexistence across ecosystems

Science, Journal Year: 2024, Volume and Issue: 383(6688)

Published: March 14, 2024

The worldwide loss of species diversity brings urgency to understanding how diverse ecosystems maintain stability. Whereas early ecological ideas and classic observations suggested that stability increases with diversity, theory makes the opposite prediction, leading long-standing "diversity-stability debate." Here, we show this puzzle can be resolved if growth scales as a sublinear power law biomass (exponent <1), exhibiting form population self-regulation analogous models individual ontogeny. We competitive interactions among populations do not lead exclusion, occurs logistic growth, but instead promote at higher diversity. Our model realigns predicts large-scale macroecological patterns. However, it an unsettling prediction: Biodiversity may accelerate destabilization ecosystems.

Ecological-network models link diversity, structure and function in the plankton food-web

Scientific Reports, Journal Year: 2016, Volume and Issue: 6(1)

Published: Feb. 17, 2016

Abstract A planktonic food-web model including sixty-three functional nodes (representing auto- mixo- and heterotrophs) was developed to integrate most trophic diversity present in the plankton. The implemented two variants - which we named ‘green’ ‘blue’ characterized by opposite amounts of phytoplankton biomass representing, respectively, bloom non-bloom states system. Taxonomically disaggregated food-webs described herein allowed shed light on how components plankton community changed their behavior different conditions modified overall functioning food web. green blue showed distinct organizations terms roles carbon fluxes between them. Such re-organization stemmed from switches selective grazing both metazoan protozoan consumers. Switches structure resulted relatively small differences efficiency material transfer towards higher levels. For instance, states, a seven-fold decrease translated into only two-fold potential planktivorous fish biomass. By linking diversity, function food-web, discuss role internal mechanisms, relying species-specific functionalities, driving ‘adaptive’ responses communities perturbations.

Linking scaling laws across eukaryotes

Proceedings of the National Academy of Sciences, Journal Year: 2019, Volume and Issue: 116(43), P. 21616 - 21622

Published: Oct. 7, 2019

Significance Metabolic scaling theory has had a profound influence on ecology, but the core links between species characteristics have not been formally tested across full domain to which claims apply. We compiled datasets spanning all eukaryotes for foremost body mass laws: metabolism, abundance, growth, and mortality. show that metabolism abundance only follow canonical ±3/4 slopes within some taxonomic groups, reveal reciprocal near ±1 slopes, broadly supporting “energetic equivalence rule.” In contrast growth follows consistent ∼3/4 many groups eukaryotes. Our findings are incompatible with metabolic basis instead point dynamics as foundational biological scaling.

Global signal of top-down control of terrestrial plant communities by herbivores

Proceedings of the National Academy of Sciences, Journal Year: 2018, Volume and Issue: 115(24), P. 6237 - 6242

Published: May 30, 2018

The theory of "top-down" ecological regulation predicts that herbivory suppresses plant abundance, biomass, and survival but increases diversity through the disproportionate consumption dominant species, which inhibits competitive exclusion. To date, these outcomes have been clear in aquatic ecosystems not on land. We explicate this discrepancy using a meta-analysis experimental results from 123 native animal exclusions natural terrestrial (623 pairwise comparisons). Consistent with top-down predictions, we found herbivores significantly reduced survival, reproduction (all P < 0.01) increased species evenness richness (P = 0.06 0.59, respectively). However, when examining patterns strength effects, few exceptions, were unable to detect different effect sizes among biomes, based local site characteristics (climate or productivity) study (study duration exclosure size). positive effects only significant studies excluding large animals located temperate grasslands. demonstrate by is pervasive process shaping communities at global scale, its highly specific predicted basic conditions. suggest including herbivore densities as covariate future will facilitate discovery unresolved macroecology trends herbivore-plant interactions.
