An integrated dataset for stakeholder perceptions of environmental change and instrumented measures of change

open access: yesData in Brief, 2018
An integrated dataset was developed that combined stakeholder perceptions of environmental change (precipitation, air temperature, water temperature, fish abundance, fish size, residential development) and comparable instrumented measures of ...

Environmental effects related to the local absence of exotic fish [PDF]

open access: yes, 2009
Given the extent of biological invasions in industrialized countries, our understanding of the determinants of overall patterns of biological invasions could gain most from consideration of why exotic species are absent from some areas, rather than from ...

Empirical evaluation of the effectiveness of South Africa's marine protected area network in representing fish communities [PDF]

open access: yes, 2011
In this study, fish community structure as sampled by shore angling, trawling, boat-based line-fishing and seine netting was compared across the EEZ of South Africa, including sites in designated MPAs.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Food Web Structure and Trophic Dynamics of a Fish Community in an Ephemeral Floodplain Lake

open access: yesFrontiers in Environmental Science, 2019
In Africa, wetlands, such as shallow, ephemeral lakes provide ecosystem services, such as water purification, food supply, and flood control but are subject to dynamic flooding/drying cycles which vary in duration from years to decades.

Proper environmental DNA metabarcoding data transformation reveals temporal stability of fish communities in a dendritic river system

open access: yesEnvironmental DNA, 2021
Protecting freshwater biodiversity is considered an ultimate challenge but depends on reliable surveys of species distribution and abundance which eDNA metabarcoding (environmental DNA metabarcoding) may offer.

Microbial communities on fish eggs from Acanthopagrus schlegelii and Halichoeres nigrescens at the XuWen coral reef in the Gulf of Tonkin [PDF]

open access: yesPeerJ, 2020
Coral reefs are an important part of the ocean ecosystem and are a vital spawning ground for marine fish. Microorganisms are abundant in this environment and play a key role in the growth and development of host species.

Structural and biochemical analysis of a B12 superbinder

open access: yesFEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.
