Paleontology has provided invaluable basic knowledge on the history of life Earth. The discipline can also provide substantial to societal challenges such as climate change. long-term perspective change impacts natural systems is both a unique selling point and major obstacle becoming more pertinent for policy-relevant bodies like Intergovernmental Panel Climate Change (IPCC). Repeated experiments without anthropogenic disturbance facilitate extraction triggers in biodiversity changes. At...
Conservation paleobiology has coalesced over the last two decades since its formal coining, united by goal of applying geohistorical records to inform conservation, management, and restoration biodiversity ecosystem services. Yet, field is still attempting form an identity distinct from academic roots. Here, we ask a deceptively simple question: What conservation paleobiology? To track development as field, synthesize complementary perspectives survey scientific community that familiar with...
Abstract Motivation We have little understanding of how communities respond to varying magnitudes and rates environmental perturbations across temporal scales. BioDeepTime harmonizes assemblage time series presence abundance data help facilitate investigations community dynamics timescales the response natural anthropogenic stressors. includes terrestrial aquatic assemblages spatial grain extent from present‐day millions years ago.

AMBI and M-AMBI are widely used biotic indices for assessing the ecological quality status of benthic macroinvertebrate communities in estuarine coastal soft-bottom habitats. Identifying species needed estimating these indices, however, is both expensive time-consuming, requires a high degree taxonomic expertise. The use proxy taxa as means subsampling target community may save time, resources, breadth expertise needed. Our study survey data from Atlantic Coast United States to test fidelity...

ABSTRACT Background Human pressures are driving the emergence of unprecedented, ‘novel’, ecological and environmental systems. The concept novel (eco)systems is well accepted by scientific community, but use measurement novelty has outgrown initial definitions critiques. There still unresolved methodological conceptual differences in quantifying that prevent a unified research approach. Framework Here we present framework guidelines to unify past future novelty. Under this framework,...
Abstract In the last 50 years, field of paleobiology has undergone a computational revolution that opened multiple new avenues for recording, storing, and analyzing vital data on history life Earth. With these advances, amount available research grown, but so too our responsibility to ensure tools infrastructures continue innovate in order best serve diverse community. This review focuses equity paleobiology, an aspirational goal, wherein all forms are collected, stored, shared analyzed...
Water management that alters riverine ecosystem processes has strongly influenced deltas and the people who depend on them, but a full accounting of trade-offs is still emerging. Using palaeoecological data, we document surprising biogeochemical consequence water in Colorado River basin. Complete allocation consumptive use river's flow altered downstream estuarine ecosystem, including abundance composition mollusc community, an important component carbon cycling. In particular, population...
AMBI and Bentix are widely used benthic indices for guiding remediation decisions under two major pieces of environmental legislation in Europe — the Water Framework Directive (WFD) Marine Strategy (MSFD). These usually incorporate all marine invertebrates a sample. Some recent studies, however, have applied these to only mollusk species due ease identifying one taxonomic group level because death assemblages (accumulated dead shells sediments) may be valuable sources data assessing baseline...
Abstract Aim Throughout the Colorado River basin, numerous dams have captured and diverted entirety of basin's c. 1.85 × 10 m 3 year −1 water, altering downstream delta ecosystem. In absence pre‐dam studies, geohistorical data can play a critical role in reconstructing ecological aspects past Here, we use to test hypothesis that shell‐drilling naticid gastropod predator, Notocochlis chemnitzii , has recently undergone human‐induced range expansion ( CRD ). Based on uncertainty literature...
Abstract As the climate changes and ecosystems shift toward novel combinations of species, methods metrics conservation science are becoming less species-centric. To meet this growing need, marine paleobiologists stand to benefit from addition new, taxon-free benthic indices live–dead analysis tool kit. These indices, which were developed provide actionable, policy-specific data, can be applied readily preservable component communities (e.g., mollusks) assess ecological quality status entire...
Abstract Data compilations expand the scope of research; however, data citation practice lags behind advances in use. It remains uncommon for users to credit producers professionally meaningful ways. In paleontology, databases like Paleobiology Database (PBDB) enable assessment patterns and processes spanning millions years, up global scale. The status quo creates an imbalance wherein publications drawing from PBDB receive significantly more citations (median: 4.3 ± 3.5 citations/year) than...
River systems worldwide have been modified for human use and the downstream ecological consequences are often poorly understood. In Colorado estuary, where upstream water diversions limited freshwater input during last century, mollusc remains from several hundred years suggest widespread change. The once abundant clam Mulinia modesta has undergone population declines of approximately 94% populations predators relying on this species as a food source probably declined, switched to...

Abstract The effects of overdispersion and zero inflation (e.g., poor model fits) can result in misinterpretation studies using count data. These have not been evaluated paleoecological predation are further complicated by preservational bias time averaging. We develop a hierarchical Bayesian framework to account for uncertainty from estimates specimen trace counts. demonstrate its application published data on drilling predators their prey time-averaged death assemblages the Great Barrier...

Fish mortality through floodplain pumping stations is a recognised global issue, but few studies have quantified the degree of that occurs during pumping. We investigated potential passive acoustic monitoring (PAM) as tool to record sounds made by fish and their likely they passed pumps downstream migration. The properties freshly killed eels were fed an existing pump station compared those goldfish (Carassius auratus). Processing analysis data enabled development ‘eel-specific’ algorithm...
Climate and ecosystems exhibit dynamic behavior across various timescales, but existing studies often focus on singular timescales when examining ecosystem responses to climate. Here we develop a conceptual analytical framework using spectral analysis that examines continuum of from hundreds thousands years. By comparing power spectra vegetation turnover climate in the last 1.1 million years, observe is step with at intermediate frequencies (10-2 10-3 years-1) decoupled high (> 10-2...
