Linkages between flow regime, biota, and ecosystem processes: Implications for river restoration

open access: yesScience, 2019
River restoration guided by research Human activities have altered the flow regimes of many of Earth's rivers, with negative impacts on biodiversity, water quality, and ecological processes.

Distribution and Persistence of Diflubenzuron and Teflubenzuron in the Marine Environment Around Salmonid Aquaculture Facilities

open access: yesFrontiers in Marine Science, 2021
To achieve a sustainable salmonid aquaculture industry, the environmental impacts of chemicals used to treat sea lice (Caligidae) infestations need to be considered.

Tip dating supports novel resolutions of controversial relationships among early mammals [PDF]

open access: yes, 2020
The estimation of the timing of major divergences in early mammal evolution is challenging due to conflicting interpretations of key fossil taxa. One contentious group is Haramiyida, the earliest members of which are from the Late Triassic.

Nearshore Pelagic Influence at the SW Margin of the Paratethys Sea—Examples from the Miocene of Croatia

open access: yesGeosciences, 2022
(1) The ancient Paratethys Sea was a spacious inland salt-water basin, extending from the Alps, over Central Europe, to Central Asia. The southwestern part of its central area, the Croatian part of the Pannonian Basin System (CPBS), is generally known ...

The mid-Miocene Zhangpu biota reveals an outstandingly rich rainforest biome in East Asia

open access: yesScience Advances, 2021
The Zhangpu biota provides a new insight into biodiversity redistribution during the Mid-Miocene Climatic Optimum. During the Mid-Miocene Climatic Optimum [MMCO, ~14 to 17 million years (Ma) ago], global temperatures were similar to predicted ...

Robust monomer-distribution biosignatures in evolving digital biota [PDF]

open access: yes, 2011
Because organisms synthesize component molecules at rates that reflect those molecules' adaptive utility, we expect a population of biota to leave a distinctive chemical signature on their environment that is anomalous given the local (abiotic) chemistry.

Evolution of the Distribution and Dynamic of Microplastic in Water and Biota: A Study Case From the Gulf of Gabes (Southern Mediterranean Sea)

open access: yesFrontiers in Marine Science, 2022
Marine plastic pollution represents a major problem owing to its increasing presence in the environment, persistence and ability to spread in every compartment in the form of small plastic particles, namely microplastics (MPs).

DNA barcode reference libraries for the monitoring of aquatic biota in Europe: Gap-analysis and recommendations for future work

open access: yesbioRxiv, 2019
Effective identification of species using short DNA fragments (DNA barcoding and DNA metabarcoding) requires reliable sequence reference libraries of known taxa.
