Abstract. The youngest fossil record is a crucial source of data documenting the recent history marine ecosystems and their long-term alteration by humans. However, human activities that reshape communities habitats also alter sedimentary biological processes control formation archives recording those impacts. These diverse physical, geochemical, disturbances include changes in sediment fluxes due to alluvial coastal landscapes, seabed disturbance bottom trawling ship traffic, ocean acidification deoxygenation, removal native species, introduction invasive ecosystem engineers. novel modify sedimentation rates, depth intensity mixing, pore-water saturation state, preservation potential skeletal remains – parameters controlling completeness spatiotemporal resolution record. We argue humans have become major force transforming nature ways can both impede improve our ability reconstruct past ecological climate dynamics. A better understanding feedback between impacts on offers new research opportunities tools for interpreting geohistorical ongoing anthropogenic transformation ocean.

Abstract Conservation paleobiology, an expanding field, employs taphonomy tools to investigate past environmental conditions and organisms before human impacts, thereby addressing key conservation issues. This review examines the concepts, approaches events in emphasizing aquatic coastal often-overlooked contributions from Brazil South America. America, with its vulnerable biodiversity, unique geology rich fossil diversity, is a natural laboratory for understanding ecosystems—a considerable potential as center leading paleobiology research. However, America underrepresented, contributing only 5% of total publications (67% it Brazil). Most American authors are geoscientists publishing mainly on mollusks, also they produced fewer studies than those more developed countries. Noteworthy, Brazilian National Council Scientific Technological Development ranks third globally funding articles. Clearly, still predominantly practiced nations geoscience fields. Other challenges include underutilization geohistorical data gap between theory practice. To address these issues, future should integrate conservationist perspectives align them societal needs. Hence, anticipated growth could bolster promote sustainability generations.

Abstract The Mediterranean Sea is recognized as a hotspot of marine biodiversity. Analysing its past biodiversity can help in understanding species' response to climate change.

Long-term baseline data that allow tracking how predator–prey interactions have responded to intensifying human impacts are often lacking. Here, we assess temporal changes in benthic community composition and between drilling predatory gastropods their molluscan prey using the Holocene fossil record of shallow northern Adriatic Sea, which is characterized by a long history transformation. Molluscan assemblages differ Isonzo Po prodelta, but both show consistent trends abundance dominant species. Samples mollusc collected at high stratigraphic resolution indicate frequencies drastically declined prodelta since mid-twentieth century, while weaker trend more condensed sediments not statistically significant. The decrease predation intensity turnover linked loss increased relative less-preferred during most recent decades.

Mollusk death assemblages are formed by shell remnants deposited in the surficial mixed layer of seabed. Diversity patterns tropical marine habitats still understudied; therefore, we aimed to investigate taxonomic, phylogenetic, and functional diversity mollusk at regional local scales coral reef sands seagrass meadows. We collected sediment samples 11 sites within two shallow gulfs Northwestern Caribbean Sea Southeastern Gulf Mexico. All shells were counted identified species level classified into biological traits. 7113 individuals belonging 393 (290 gastropods, 94 bivalves, nine scaphopods). assemblage structure showed many similarities between given their geological biogeographical commonalities. Reef had higher richness than seagrasses likely because a more favorable balance productivity-disturbance. dominated epifaunal herbivores feeding on microphytobenthos bysally attached bivalves adapted intense hydrodynamic regime. In meadows, suspension feeders exposed chemosynthetic infaunal where oxygen replenishment was limited. Time averaging order 100 years, with stronger effects compared Our research provides evidence high coastal sediments as result influence scale-related processes habitat type. study highlights convenience including phylogenetic traits, well dead shells, for complete assessment biodiversity.

Abstract Humans have dramatically transformed ecosystems over the previous millennia and are potentially causing a mass extinction event comparable to others that shaped history of life. However, only fraction these impacts has been directly recorded, limiting conservation actions. Conservation paleobiology leverages geohistorical records offer long-term perspective on biodiversity change in face anthropogenic stressors. Nevertheless, field's on-the-ground contributions outcomes still developing. Here, we present an overview directions which paleobiological research could progress aid coming decades using elasmobranchs (sharks, rays, skates)—a highly threatened group with rich fossil record—as model. These guided by areas overlap between expert-led list current elasmobranch priorities available historical records. Four topics emerged for address open questions science conservation: (1) baselines, (2) ecological roles, (3) threats, (4) priorities. Increasingly datasets novel analytical frameworks exciting opportunities apply record practice. A similar approach be extended other clades. Given synthetic nature topics, encourage collaboration across timescales practitioners safeguard future our planet's rapidly disappearing species.
