Host-associated microbiomes contribute in many ways to the homeostasis of metaorganism. The microbiome's contributions range from helping provide nutrition and aiding growth, development, behavior protecting against pathogens toxic compounds. Here we summarize current knowledge diversity importance microbiome animals, using representative examples wild domesticated species. We demonstrate how beneficial ecological roles animal-associated can be generally grouped into well-defined main categories microbe-based alternative treatments applied mitigate problems for both economic conservation purposes crucial about host-microbiota symbiotic interactions. suggest a Customized Combination Microbial-Based Therapies promote animal health practice sustainable husbandry. also discuss connections threats associated with biodiversity loss, microorganism extinction, emerging diseases, such as COVID-19 pandemic.

The early Aurignacian dispersal of modern humans into westernmost Eurasia

Proceedings of the National Academy of Sciences, Journal Year: 2020, Volume and Issue: 117(41), P. 25414 - 25422

Published: Sept. 28, 2020

Significance We report the remarkable discovery of an early Aurignacian occupation, ∼5,000 years older than any Upper Paleolithic site in westernmost Eurasia. The archaeological and radiocarbon data provide definitive evidence that modern humans were western Iberia at a time when, if present all, Neanderthal populations would have been extremely sparse. This has important ramifications for our understanding process human dispersal replacement populations. results support very rapid, unimpeded across Eurasia notion climate environmental change played significant role this process.

A Neandertal dietary conundrum: Insights provided by tooth enamel Zn isotopes from Gabasa, Spain

Proceedings of the National Academy of Sciences, Journal Year: 2022, Volume and Issue: 119(43)

Published: Oct. 17, 2022

The characterization of Neandertals’ diets has mostly relied on nitrogen isotope analyses bone and tooth collagen. However, few data have been recovered from bones or teeth Iberia due to poor collagen preservation at Paleolithic sites in the region. Zinc isotopes shown be a reliable method for reconstructing trophic levels absence organic matter preservation. Here, we present results zinc (Zn), strontium (Sr), carbon (C), oxygen (O) trace element ratio analysis measured dental enamel Pleistocene food web Gabasa, Spain, characterize diet ecology Middle Neandertal individual.

Further work could help identify if such isotopic peculiarities (lowest highest web) are metabolic and/or dietary specificity Neandertals.

Chronological constraint of Neanderthal cultural and environmental changes in southwestern Europe: MIS 5–MIS 3 dating of the Axlor site (Biscay, Spain)

Journal of Quaternary Science, Journal Year: 2023, Volume and Issue: 38(6), P. 891 - 920

Published: May 8, 2023

ABSTRACT The cave site of Axlor (Biscay, Spain) preserves one the most informative Middle Palaeolithic (MP) records for North Atlantic Iberian region, though its age remains poorly known. Here we use single‐grain optically stimulated luminescence (OSL) and thermally transferred OSL (TT‐OSL) dating sediments to improve constraint Axlor's MP succession (levels N–B). Our new ages are consistent with previously published terminus ante quem 14 C (>42.9 cal ka bp ), suggest sequence accumulated during a period ~50 kyr. levels N–F were deposited ~100–80 ka, probably marine isotope stage (MIS) 5d–a, while D B ~70 respectively, MIS 4 mid‐MIS 3. results indicate that major faunal technological turnovers occurred towards end 5, potentially coinciding broader environmental climatic changes. Quina record, dated here onset 4, is oldest in Europe. Comparisons neighbouring sites point complex regional chronologies development this particular behaviour, detailed correlations other sequences remain difficult due their poor chronological attributes. present study highlights important role optical can play elucidating evolution across southwestern

Ocean Optimism: Moving Beyond the Obituaries in Marine Conservation

Annual Review of Marine Science, Journal Year: 2020, Volume and Issue: 13(1), P. 479 - 499

Published: June 6, 2020

While the ocean has suffered many losses, there is increasing evidence that important progress being made in marine conservation. Examples include striking recoveries of once-threatened species, rates protection habitats, more sustainably managed fisheries and aquaculture, reductions some forms pollution, accelerating restoration degraded use its habitats to sequester carbon provide clean energy. Many these achievements have multiple benefits, including improved human well-being. Moreover, better understanding how implement conservation strategies effectively, new technologies databases, increased integration natural social sciences, indigenous knowledge promise continued progress. Enormous challenges remain, no single solution; successful efforts typically are neither quick nor cheap require trust collaboration. Nevertheless, a greater focus on solutions successes will help them become norm rather than exception.

The late persistence of the Middle Palaeolithic and Neandertals in Iberia: A review of the evidence for and against the “Ebro Frontier” model

Quaternary Science Reviews, Journal Year: 2021, Volume and Issue: 270, P. 107098 - 107098

Published: Sept. 21, 2021

In the Franco-Cantabrian region and Catalonia, Upper Palaeolithic begins with three assemblage-types found in stratigraphic order through interval between 45,000 37,000 years ago: Châtelperronian, Protoaurignacian, Early Aurignacian. A stone tool, Châtelperron point, a bone split-based are index fossils of first last, respectively, but neither was ever elsewhere Iberia. This observation triggered proposition that, regions situated to south River Ebro drainage, Middle persisted until time when Aurignacian gave way Evolved Aurignacian, which is documented across all Iberia by assemblages containing its fossil, Roc-de-Combe bladelet. Put forth thirty ago, this Frontier model support little radiometric evidence then available. Since, it has been shown that most apparently late occurrences were an artefact dating error, caused incomplete decontamination radiocarbon samples, while claims have surfaced for be more widespread than hitherto thought. While validity Frontier's premises thereby called into question, continued provided excavation new sites, re-excavation old ones, application luminescence techniques, robustly pre-treated samples.
